      WOMEN & COMPUTING

      There is mounting evidence that many women opting for careers in computing
      either drop out of the academic pipeline or choose not to get advanced
      degrees and enter industry instead. Consequently, there are
      disproportionately low numbers of women in academic computer science and the
      computer industry. The situation may be perpetuated for several generations
      since studies show that girls from grade school to high school are losing
      interest in computing.

      Statistics, descriptions offered by women in academic and industrial
      computing, and the research findings reported later in this article indicate
      that much is amiss. But the point of what follows is not to place
      blame--rather it is to foster serious reflection and possibly instigate
      action. It behooves the computer community to consider whether the
      experiences of women in training are unique to computer science. We must ask
      why the computer science laboratory or classroom is "chilly" for women and
      girls. If it is demonstrated that the problems are particular to the field,
      it is crucial to understand their origins. The field is young and flexible
      enough to modify itself. These women are, of course, open to the charge that
      they describe the problems of professional women everywhere. But even if the
      juggling acts of female computer scientists in both academia and industry are
      not particular to computing American society cannot afford to ignore or
      dismiss their experiences; there is an indisputable brain drain from this
      leading-edge discipline.

      A look at statistics reveals a disquieting situation. Accordingly to Betty
      M. Vetter, executive director of the Commission on Professionals in Science
      and technology in Washington, DC, while the number of bachelor's and master's
      degrees in computer science are dropping steadily for both men and women,
      degrees awarded to women are dropping faster, so they are becomming a smaller
      and smaller proportion of the total. Bachelor's degrees peacked at 35.7% in
      1986, masters also peaked that year at 29.9%, and both are expected to
      continue to decline. "We have expected the numbers to drop for both, due to
      demographics such as fewer college students," says Vetter, "but degrees
      awarded women are declining long before reaching parity." (See Table I.)
      Vetter also would have expected computer science to be "a great field for
      women," as undergraduate mathematics has been; female math majors have earned
      45% of bachelor's degrees during the 1980s. On the other hand, math Ph.
      D.'s awarded to women have gone from only 15.5% to 18.1% in this decade,
      which is more in line with computer science Ph.D.'s earned by women. In
      1987, 14.4% of all computer science Ph.D's went to women; this number
      declined to 10.9% the following year. Although the number almost doubled
      between 1988 and 1989 with women receiving 17.5% of Ph.D's, Vetter points out
      that the number remains very small, at 107. Since these figures include
      foreign students who are principally male, women constitute a smaller
      percentage of that total than they do of Ph.D's awarded to Americans. But
      while American women received 21.4% of Ph.D's awarded to Americans, that is
      not encouraging either, says Vetter. Again, the number of American women
      awarded computer science Ph.D.'s was minuscule, at 72. And taking a longer
      view, the awarding of significantly fewer bachelor's and master's degrees to
      women in the late 1980s will be felt in seven to eight years, when they would
      be expected to receive their Ph.D.'s.

      How do these figures compare with those of other sciences and engineering?
      In her 1989 report to the National Science Foundation, "Women and Computer
      Science," Nancy Leveson, associate professor of information and computer
      science at the University of California at Irvine, reports that in 1986,
      women earned only 12% of computer science doctorates compared to 30% of all
      doctorates awarded to women in the sciences. Leveson notes, however, that
      this includes the social sciences and phychology, which have percentages as
      high as 32 to 50. But the breakout for other fields is as follows: physical
      sciences (16.4%), math (16.6%), eletrical engineering (4.9%), and other
      engineering ranges from 0.8% for aeronautical to 13.9% for industrial.

      Those women who do get computer science degrees ae not pursuing careers in
      academic computer scinces. Leveson says women are either not being offered
      or are not accepting faculty positions, or are dropping out of the faculty
      ranks. Looking at data taken from the 1988-89 Taulbee Survey, which appeared
      in Communications in September, Leveson points out that of the 158 computer
      science and computer engineering departments in that survey, 6.5 percent of
      the faculty are female. One third of the departments have no female faculty
      at all. (See Tables III and IV.)

      Regarding women in computing in the labor force, Vetter comments that the
      statistics are very soft. The Bureau of Labor Statistics asks companies for
      information on their workforce, and the NSF asks individuals for their
      professional identification; therefore estimates vary. Table II shows that
      this year, women comprise about 35% of computer scientists in industry. And
      according to a 1988 NSF report on women and minorities, although women
      represents 49% of all professionals, they make up only 30% of employed
      computer scientists. "There is no reason whey women should not make up half
      the labor force in computing," Betty Vetter says, "It's not as if computing
      involves lifting 125 pound weights."

      The sense of isolation and need for a community was so keen among women in
      computing, that in 1987 several specialists in operating systems created
      their own private forum and electronic mailing list called "Systers."
      Founded and operated by Anita Borg, member of the research staff at DEC's
      Western Research Lab, Systers consists of over 350 women representing many
      fields within computing. They represent 43 companies and 55 universities
      primarily in the United States, but with a few in Canada, the United Kingdom,
      and France. Industry members are senior level and come from every major
      research lab. University members range from computer science undergraduates
      to department chairs. Says Borg, "Systers' purpose is to be a forum for
      discussion of both the problems and joys of women in our field and to provide
      a medium for networking and mentoring." The network prevents these women,
      who are few and dispersed, from feeling that they alone experience certain
      problems. Says Borg, "You can spit out what you want with this group and get
      women's perspectives back. You get a sense of community." It is sexist to
      have an all-women's forum? "Absolutely not," says Borg, "It's absolutely
      necessary. We didn't want to include men because there is different way that
      women talk when they're talking with other women, whether it be in person or
      over the net. Knowing that we are all women is very important."

      mailing list may send email to systers-request@decwrl.dec.com)

      The burden from women in computing seems to be very heavy indeed.
      Investigators in gender-related research, and women themselves, say females
      experience cumulative disadvantages from grade school through graduate school
      and beyond. Because statistical studies frequently come under fire and do
      not always explain the entire picture, it is important to listen to how women
      themselves tell their story. In the Sidebar entitled "Graduate School in the
      Early 80s," women describe experiences of invisibility, patronizing behavior,
      doubted qualifications, and so on. Given these experiences, it is not
      surprising that many women find the academic climate inclement. But while
      more women may choose to contribute to research in industry, is the computer
      business really a haven for women, or just the only alternative? In the
      Sidebar entitled "The Workplace in the late '80s," women in industry also
      tell their story and describe dilemmas in a dialogue on academia versus
      industry; this discussion erupted freely last Spring on Systers. In
      addition, findings of scholars conducting gender-related research are
      presented in a report of a workshop on women and computing. Finally,
      Communications presents "Becoming a Computer Scientist: A Report by the ACM
      Committee on the Status of Women in Computer Science." A draft was presented
      at the workshop and the report appears in its entirety in this issue.

      Report on a Meeting

      To probe further into the reasons why girls and women are not pursuing
      computing in the same numbers as boys and men, and to recommend ways to
      reverse this trend, a workshop was held at the National Educational Computing
      Conference last June. This year, this influential and decade-old conference
      drew 2,414 authorities in computing and education and 1,500 people from
      industry. Entitled "In Search of Gender-Free Paradigms for Computer Science
      Education," the workshop was organized and chaired by C. Dianne Martin, an
      assistant professor at George Washington University's Electrical Engineering
      and Computer Science department. It's specific goal was to examine the
      premise that the decline in the number of women selecting computer science
      majors can be attributed to a male-oriented paradigm in the field. Martin
      invited 12 scholars (See Workshop Participants, p.) conducting gender-related
      research in computer science education to present their latest findings and
      to participate in brainstorming sessions that resulted in recommendations.
      Hightlights of the day-long workshop follow.

      In her opening statement, Martin noted that many researchers observe that the
      computer culture is uncomfortable for girls and women. They are ill at ease
      in a field that seems to encourage "highly focused, almost obsessive
      behavior," as the key to success she said, summarizing comments by Eric
      Roberts at a recent Washington student society (Pugwash) meeting. She also
      alluded to perceived sex biases in the profession, citing two recent national
      statistical studies of female engineering students engineering students by
      Eleonor Baum, Dean of the School of Engineering at Cooper Union. Baum's
      investigations showed that 70% of women felt they had to work harder than
      their male counterparts to get comparable pay, 58% felt that harassment of
      some sort was prevalent in the workplace, 50% felt that they viewed ethical
      issues differently than did their male counterparts, 39% felt they would be
      penalized if they took maternity leave, and a whopping 78% felt they received
      comparable pay when they started, but were not promoted as rapidly. A third,
      independent study supported the last belief; while women started out with
      comparable pay, within 10 years they were 25% behind their male counterparts.

      Chaos In Computer

      Classrooms

      Lesley S. Klein, instructor of information systems at Pace University and a
      computer science teacher in middle school and high school, described the
      chaotic state of computer science education throughout pre-college levels.
      Working under the auspices of the Board of Cooperative Educational Services,
      funded by New York State Department of Education, Klein observes upper middle
      income schools of this public school system. Despit its relative wealth,
      there is often a low budget for computer science and no curriculum, she said.
      Computing is taught by teachers' aides or by media center administrators who
      have had in-service training. "Occasionally students are fortunate to have a
      classroom teacher who has an interest in computers as a hobby or has taken
      some computer education courses," Klein reports in her paper, "Female
      Students' Under-achievement in Computer Science and Mathematics: Reasons and
      Recommendations." "Some more adventurous teachers have incorporated LOGO or
      Lego Logo programming into the curriculum, but there is no apparent formal
      plan nor carryover from one grade level to the next," Klwin continues. There
      are neither goals nor minimum standards established for both teacher training
      and the material to be covered. Not until the seventh and eight grades does
      the study of computers, logic, or BASIC programming emerge. PASCAL and C
      programming and introductions to data processing are offered in secondary
      schools, but there is still great variation in instructors' backgrounds and
      levels of competence. Some are math teachers, have master's degrees in
      computer science, or have taken graduate courses, but others are industrial
      arts teachers who have received minimal training. On the other hand,
      sometimes industrial arts teachers are better qualified than math teachers.
      Although high school curricula for computer literacy and computer science
      courses do exists (ACM made several recommendations on curricula five years
      ago and plans to revise them by 1991) there is little support to implement
      them and there is no uniformity from state to state.

      But one would expect this sorry state of affairs to affect boys and girls
      equally. Not so. According to Klein, girls "demonstrate more insecurity and
      lack of self-confidence in math and science during transition periods" like
      entering middle school and entering high school. In middle school, for
      example, boys use pirated software, she says, and the girls follow the school
      rules and are in the boys' way. "The computers are always consumed by the
      boys who rush in, desperate to continue where they left off the day before in
      Oregon Trail, Karateka, or Carmen San Diego. An occasional girl wanders in,
      but would practically need interference from the heavens to gain access to
      these monopolized computers," Klein says. Given these different styles of
      behavior, Klein sees the need for a formal computer science curriculum for
      grades seven through twelve as well as mandatory requirement that every high
      school student take an introduction to computer science. Because many in the
      educational community are unaware that recommended curricula exist, Klein
      stresses the need for support for the distribution and implementation of
      curricula. In addition, there should be more uniform teacher training that
      improves computer skills and lesson presentation while "specifically
      addressing the motivation of female students."

      Women and Girls of Color

      The problems in computer science education for girls in well-to-do schools
      are substantial, but they are mild in comparison to those that girls from
      minority groups face in their schools. Carol E. Edwards, of the Southern
      Coalition for Educational Equity, Atlanta, Georgia, addressed the
      implications of the computer culture for girls and women of color. As the
      director of Project Micro, Edwards runs a program devoted to making personal
      computers available to minority children and to using those computers to
      teach higher-order thinking skills. The educational opportunities for these
      women and girls are so poor, she said, that they amount to racial, ethnic,
      and class discrimination. Both boys and girls of color go to schools with
      low teacher expectations, more substitute teachers, less experienced
      teachers, and frequent relegation to lower educational tracks. In math, for
      example, girls of color are disproportionately represented on slower tracks.

      Tracking itself is part of systemic problems in minority schools; it is an
      example of structural practices that remain instituted even though they have
      been shown to benefit only the top one % of students, Edwards said. Besides
      these educational barriers, both boys and girls of color face cultural
      barriers such as lack of role models and lack of parental encouragement.
      They lack science-related opportunities and often never see computers. But
      if they do use computers, they are not likely to stay after school in the
      computer lab. That is seen as scholarly and boys of color measure
      self-esteem in nonacademic ways, she said. Girls are unlikely to stay after
      school because they are usually responsible for younger siblings at home.
      These barriers lead to disadvantages that are cumulative; the combination of
      being poor, a member of a minority, and female lowers perceptions and
      attitudes toward math and computers proportional to the level of
      disadvantage, she said.

      Sex-Blased Software

      Any computer science curriculum, whether implemented in a wealthy or
      disadvantaged school must involve the selection of software. But studies
      show sex bias in educational software. In an effort to understand why the
      comouter "is more alluring to boys than it is to girls," Charles W. Huff and
      Joel Cooper have found sex biases due to the stereotypes of software
      designers. Huff, who was with Carnegie-Mellon University during this
      research and is now an assistant professor of psychology at St. Olaf College,
      Northfield, MN, briefly presented their findings to the workshop. Because
      their results are far-reaching and possibly related to software use in the
      workplace, Huff's comments as well as those from an interview with Cooper,
      chairman of Princeton University's Department of Psychology, are presented
      here.

      Beginning with sex differences in the impact of television violence on
      children, Cooper is the author of many gender-related studies and has
      collaborated with other researchers (including Joan Hall, Lori Nelson, Diane
      Mackie, all from Princeton, and Gita Wilder of the Educational Testing
      Service). Although the media has reported the general conclusion that
      televised violence makes children act more aggressively, on closer inspection
      of the data Cooper found this "true almost exclusively for boys, not girls."
      Most investigators stopped studying girls because the early data showed no
      effect so as they proceeded with their research they used only males. "It is
      an important observation that boys become more aggressive when they watch
      television, but it should be equally interesting that girls don't, Cooper
      says. He and his collegues wondered whether the difference was due to
      different processes in males and females or to a predominance of male TV
      heroes and villains. They also decided to investigate the impact of
      aggression via other media, particularly video games and middle school
      children. At that time, the early 1980s, graphics were so primitive that
      characters were neither male nor female. This allowed the researchers to
      introduce aggressive and nonaggressive video games without concern for the
      sex of the protagonists and antogonists. In that study, girls who played
      aggressive video games became more aggressive than boys did. Says Cooper,
      "the impact was greater on girls that on boys." But Cooper also observed
      that when they told the children they were going to play a video game like
      Missile Command, the boys got very excited but the girls were unenthusiastic.
      They said either "I don't want to play that," "I can't play that," or "I'm
      not good at that." In fact, the girls were quite good at playing such games.
      "They were just as good at it as the boys were," said Cooper, "But what they
      were telling us was quite significant. They were saying, 'This makes me
      very, very nervous, especially to do it in front of you.'"

      In another classroom in the same school, computerized learning had just begun
      with educational software having a metaphor much like Missile Command. "In
      order to motivate kids, educators were using a metaphor or fantasy that our
      research showed was extremely exciting for boys and anxiety producing for
      girls," Cooper explains. Next, he and Huff "hypothesized that the
      expectations software designers hold about the users of software they design
      are central in determining the way the user and the software interact."

      To test this social psychological model--that expectations of one person
      about another can shape their interaction--Huff and Cooper asked educators
      with programming experience to design software for either boys, girls, or
      students. The programs for both boys and students were the most game-like
      whereas those intended for girls were classifiable as learning tools.
      "Programs written for students are written, it seems, with only boys in
      mind," Huff and Cooper Cooper write in "Sex Bias in Educational software: The
      Effect of Designers' Stereotypes on the Software They Design." "...That is,
      [male and female designers] may have been simply using "male" as the default
      value of "student." Therefore, "It is not the computer, or even the
      software, that is at the root of the sex bias in software, but the
      expectations and stereotypes of the designers of the software," Huff and
      Cooper conclude.

      One obvious implication of this male bias is that educational software may be
      designed to appeal to boys "without consideration of the effect on girls'
      motivation to use them or on girls' educational profit from them. This
      certainly cannot be a good thing." Children using software designed for the
      opposite sex are more anxious after they interact with the program, and that
      anxiety leads to lowered scores in the subject the program was intended to
      teach. "However, this only occurs if the children are using the program in
      public, that is, in a computer lab with other chilren present," say the
      authors." When theprograms are used privately, these differences do not
      emerge." Huff and Cooper conclude that not only is the software
      sex-stereotyped due to designers' expectations, but that the situation in
      which the software is presented is at fault.

      Challenging Dijkstra:

      Software Packages vs.

      Procedural

      Programming?

      One exploratory idea proposed by Danielle Bernstein, associate professor of
      computer science at Kean College, Union, NJ, was a new curriculum paradigm
      for computer science education--using software packages instead of procedural
      programming as an introduction to computer science. She has designed and
      taught an advanced course, "Conceptual Understanding of Software Packages,"
      which requires previous computing knowledge but which illustrates that
      packages "have a place" in computer science education. Her next step is to
      design a course introducing computer science fundamentals with packages.

      According to Bernstein, researchers have shown that previous experience,
      feelings of self-efficacy, and mathematically ability, are major predictors
      of success in computer science courses. Defining self-efficacy as "the
      feeling that one is in control of the machine and can make a difference in
      the operation of the machine," Bernstein said that this factor, which differs
      between men and women, may cause women's lower level of achievement in
      computing. Previous experience often leads to feelings of self-efficacy, she
      said, and much of that experience results from self-initiated investigations
      outside of classes. "However can we offer women the same experience?" she
      asked. Again, citing other researchers, she noted that while men may be
      passionate about computers, women use computers as tools for solving
      problems. When women do not see computers as efficient tools, they lose
      interest, but when both sexes see computers as tools, they perform equally
      well. But given the current computer science curriculum including BASIC,
      Pascal, and the emphasis on step-by-step division of functions, and formal
      planning in formal languages, women lose interest, she said.

      Arguing for her new approach, Bernstein said that software packages are less
      tied to mathematics and allow students to do something functional quickly.
      Because software packages "do real work real soon," she said, "women, who
      perceive computers as tools rather than toys, would see the purpose of
      computer." Initial success and accomplishing work bring immediate
      gratification; exploration is easier and more natural, and mistakes are less
      costly and visible with databases. Group work, which women prefer, occurs
      more spontaneously with packages, Bernstein added.

      But is this computer science? Yes, according to Bernstein. Software
      packages can provide a superior introduction to computer science compared to
      procedural languages. Teaching sophisticated applications can illustrate and
      reinforce computer concepts like files, records, fields, memory, secondary
      storage, Boolean operations, and the format versus content of variables, she
      said. Packages involve data structures, word processing deals with string
      data, and spreadsheets have implied structures. In database management
      systems, the user actually defines the data structure, whereas with Cobal and
      Pascal the data structures are contained in the programs. "These topics
      (files, records, etc.) can be examined without the overhead of extensive
      program planning or syntax problems that can get in the way for a beginner,"
      said Bernstein. "Students may then be able to transfer these concepts to
      procedural programming successfully."

      Referring to a debate on teaching computer science, which appeared in the
      December 1989 issue of this publication, and specifically to Edsger
      Dijkstra's article, "On the Cruelty of Really Teaching Computing Science,"
      Bernstein challenged his proposal to turn an introdutory programming course
      into one on formal mathematics. Such a course would use an unimplemented
      programming language "so that students are protected from the temptation to
      test their programs," she said, quoting Dijkstra. Bernstein disagrees with
      this approach because it would discourage those who wan to "see, tinker,
      experiment, and interact" with computers in order to understand principles.
      And so, she says, Dijkstra's approach would cause computer science majors to
      further dwindle.

      In concluding her paper, Bernstein wrote: "The teaching of software concepts
      has parallel the advances in software development. Each time functional
      software has gotten further away from the details of the hardware, there has
      been a cry that computer science is being watered down. But each step has
      encouraged more diverse people to deal with computers. Serious conceptual
      understanding of application packages will continue this trend." At the
      workshop, she stated, "To me, (Dijkstra's approach) means, 'Computer science
      is getting too easy. Let's keep the riff-raff out.'"

      Academia vs. Industry

      Thos women with an interest in computer science who do begin preparing for
      advanced degrees face enormous barriers, according to Henry Etzkowitz,
      associate professor of sociology at SUNY Purchase and visiting scientist at
      Columbia University's Computer Science Department. Funded by the NSF, his
      study, co-authored by Carol Kemelgor and Michael Neuschatz, is titled "The
      Final Disadvantage: Barriers to Women in Academic Science and Engineering."
      The study encompasses women in computer science, electrical engineering,
      chemistry and physics. At a leading research university 350 students and 76
      dropouts were identified; they and their faculty were inteviewed; and data
      were collected from academic records to determine the receptivity of their
      cultures to women graduate students and faculty. "Our specific aim was to
      determine whether national background of faculty members was associated with
      bias toward women graduate students," said Etzkowitz. He found that while
      fewer women had nonwestern faculty advisors, those who did reported less bias
      toward women as scientists. This was particularly true when the faculty
      advisors were Chinese and Indian. For these faculty, women clearly held
      secondary social status, yet sexual identity was viewed as separate from
      work, Etzkowitz explained. "This separation allowed them to view women as
      scientists without confusion among sexual identity, occupational, and social
      status." Male faculty members from Mediterranean and Middle Eastern
      countries, on the other hand, were most often reported to be prejudiced
      against women. Etzkowitz also found "sexual separation of scientists," that
      is, certain areas of science are labelled as peculiarly male or female, which
      leads both sexes to avoid certain areas. Computer science theory, for
      example, is de facto off limits to women, in much the same way as particle
      physics. But natural language is assumed by some male faculty to be more
      suited to women because it is closer to traditional sex and work roles--like
      women's "traditional expressive role and typing skills in software."

      Etzkowitz found mismatched expectations between make faculty members and
      female graduate students; female students want to be taught the strategies
      needed to compete and bolster self-confidence, which male faculty presume
      means wanting "explicit direction in the conduct of research." These faculty
      thought female students wanted to do it, whereas the students how to do it,
      whereas the students reported that they wanted "guidance on how to succeed in
      the profession."

      Female students in computer science reported both overt and subtle
      discrimination with "acute consequences," said Etzkowitz. Their
      self-confidence, ability to perform, and career advancement suffered. Not
      surprisingly, women seek out female faculty. But unlike men, who sign up
      with a female faculty member only after she has distinguished herself in the
      field, female students sign up because they want a sympathetic mentor. One
      solution found by electrical engineering female graduate students was to
      undertake research in industry, where they were often able to find women
      mentors.

      Another factor pushing women from academia to industry is the "tenure clock
      versus the biological clock." One woman in Etzkowitz's study went to work
      for IBM immediately upon graduating and did not even consider getting a Ph.D.
      until after her chilren were born. For her, as for most women, the academic
      route and tenure were incompatible with having a family. In computer
      science, "pregnancy is discouraged and graduate women who have children are
      encouraged to take leaves of absence that tend to become permanent
      withdrawals." Women expect this and it creates anxiety. Once they have
      their degrees, going into academia part-time is infeasible and leaves of
      absence often result in permanent attrition. According to Etzkovitz, these
      women find they must choose between two approaches: they can either follow
      the "male model" for success in academia, which demands driven, if not
      obsessive devotion before tenure, and the publish-or-perish pressures that
      can lead to exploiting as many students as possible. Or they can go into
      industry, where their jobs are more nine-to-five and it is a little easier to
      balance their career and family needs. Relatively few women adopt the first
      model and more adopt the second, he said.

      Etzkowitz concluded that structural barriers could be reduced with the
      development of a critical mass of women faculty and graduate students in
      computer science departments. He proposed changing the tenure structure to
      allow a more flexible timeclock and involving students and faculty in the
      faculty-recruiting process. He suggested that aggressive intervention was
      needed on the part of funding agencies to ensure these changes.

      Recommendations

      After the presentations, the workshop divided into working groups that
      recommended ways to expose, attract, and retain females in computing.
      Valerie Clarke, a social psychologist at Deakin University, Australia, spoke
      for the exposure group, which focused on precollege computer experiences and
      opportunities. Although this group thought it should address the entire
      curriculum through 12th grade, for practical purposes, it focused on middle
      schools only. This stage is crucial because from ages 11 to 14, "children of
      both sexes tend to turn away from computers," Clarke said. "Most children at
      the primary level have an interest in computers, if given the opportunity,
      but in the middle school peer pressure tends to direct more girls away from
      computers." In addition, at this age girls' preferences for working in
      groups and their needs for demonstrated relevance are especially great.

      The group stressed the need for a more ambitious, comprehensive curriculum
      through twelfth grade bearing in mind resources. "It's fairly useless to
      devise a curriculum that assumes you'll have one computer per two or three
      children when schools have nothing of the sort," said Clarke. Noting
      inadequate educational software and teacher training, Clarke said that as a
      result many teachers may lack confidence and self-esteem. In turn, they fear
      that their students know more than they do. So while it is very important to
      provide teachers with curriculum that is not enough; measures must be taken
      build teachers' confidence so that they use the curriculum and feel
      sufficiently in control.

      Alluding to studies indicating that a girl's potential depends to some extent
      on her mother's level of education, Clarke said we must address the more
      general education of the public through advertising and the media. Good will
      and a first-class curriculum cannot counter mothers who want to withdraw
      their children from classes or even schools if their daughters do poorly in
      computers, said Clarke.

      As presented by Danielle Bernstein, the retention group noted that women and
      disadvantaged groups, find computing courses more time-consuming than other
      courses and feel they do not receive the right number of credits for the
      number of hours worked. "They can get the same three credits for a marketing
      course, where they just read a book and understand it," she explained. And
      chemistry and physics labs do not demand indefinite periods of time for
      problem solving. To motivate these credit- and time-conscious students, the
      group suggested structured labs with exercises that can be finished before
      leaving class. Such labs could also reduce the computer culture brand of
      competitiveness that arises when people brag about the many hours they have
      spent on a system in order to get the best solution.

      Looking at how students are taught to write code, this group suggested
      encouraging students to read programs. To learn most subjects, especially
      foreign languages, students do not just write, they also learn how to read,
      said Bernstein. "Computing seems to be the only subject where we teach
      people how to write without giving them any kind of mental model. A better
      way is [to include] reading programs," Bernstein said.

      This group also addressed computer access. Since students perform better in
      private, the group sought ways to help all students afford their own
      computers for use in dorm rooms. It was suggested that colleges bury the
      price of computers in tuition so they would fall within expenses covered by
      student loans. Computers in dorm rooms would also give each student a sense
      of control; the student alone would know and have access to his or her hard
      disc's contents, for example. "When you control the environment, you have
      more self-confidence. Otherwise it's like cooking in somebody else's
      kitchen; you don't know where anything is," Bernstein said.

      To encourage high school students to pursue computing in college, the group
      recommended that college computer science departments "adopt" high schools.
      Also suggested was cascading pairing; graduate students would pair up with
      college students, college students with high school students, and so on.
      This cascading effect at lower levels would decrease dependence on those
      female computer science professors who are role models, said Bernstein.

      Industry should also provide role models: there should be a large-scale
      program for guest lecturers from industry to speak to high school students.
      In addition, industry should bring in not just college but high school
      students to work on projects. To attract industry employees and prevent them
      from regarding this as mandatory drudge work that siphons time away from
      their jobs, the group recommended that companies be responsible for rewards
      systems, but did not specify what kinds.

      To widen students' perspectives on career choices, the group suggested
      inviting not just alumnae who had been A+ students, but those who got Bs and
      Cs. Through their visits, the current student body would learn that many
      people with less-than-perfect academic records are very successful in the job
      market, Bernstein said. Dianne Martin then commented, "We will know we have
      arrived when it's OK for women to get Cs in science, math, engineering, and
      computer science. Right now, if you're not an A or B student, you don't even
      think of going into those fields." The women currently in the field are the
      high achievers only, she said. "We're not reaching the middle and average
      achievers. Yet there are average-achieving men going into those fields."

      Adding to that group's recommendations, Carol Edwards called for more
      financial aid, particularly in the form of grants. "When Reagan switched
      from grants to loans, it hurt the poorest people. It didn't hurt the people
      that he said were using the money to buy stereos when they go to college,"
      she said. The poorest people--women of color who might have small
      children--just did not see themselves going into that much debt and being
      able in the end to pay it off, she said. Edwards also called for tenure and
      promotion for superior teaching. "Just as we have people who at this point
      get tenure because of their research," she said, "we also have to look at
      superior teaching as a criterion for the tenure track."

      In his summary of the attraction workgroup's recommendations, Robin Kay
      echoed the need for parent education. We see stereotyping in the kinds of
      toys parents encourage their children to play with, and parents often assume
      that little boys should have more access to computers. "Parents are more
      inclined to buy boys computers, and if you have a computer at home when
      you're young, you get used to it." To ensure that girls are not excluded, we
      should encourage the tool approach to computers, he said. The advent of
      microcomputers allows this now because, unlike the late '70s and early '80s
      when you had to know programming in order to use computers, with personal
      computers "we have become more individualistic. You can do lots more
      tool-oriented [tasks] with computers and you don't need to program."

      And finally, regarding sex biases in software, Kay commented that companies
      believe their market is male. Further, they think that if they start
      advertising to females, they may discourage the males, Kay said. He
      suggested trying to convince companies that there is a viable female market
      they are cutting off. "If they accept that, they'll think they can make more
      money. Money does make things happen."

      In closing, Martin commented that the "most astounding two words today were
      'cumulative disadvantage.'" They indicate priorities as to where energy and
      resources should be allocated. "It turns out, that if you're a woman, and
      you're poor, and you're a minority, the disadvantage is cumulative. That's
      where we have to put cumulative resources. The research shows, without a
      doubt, that there is this cumulative effect."

      If the issues discussed here are not addressed, everyone stands to lose. The
      profession could find itself asking uncomfortable questions too late in the
      game. As it is, one wonders how many ideas, that could have been contributed
      by female talent, will never surface to enrich academic computer science.
      More broadly, what are the repercussions to our increasingly
      computer-oriented society, if women--about half the population and
      professional workforce--are not as prepared in this discipline as are men?
      Perhaps we will not have to find out.

      Why did you join CPSR?

      The need for CPSR's activities has never been greater.

       
       

      “Certainly. That seemed to be the purpose, in the London hotel. A person as clever as that must have planned this entire affair and has undoubtedly accomplished his wish and vanished long ago—or else he can never be caught because we have no way to discover him.” But she only answered that that was unlikely and slipped her arm around his neck, as she added that if anything were to happen to him, she would not have one real friend in the world. There was something pathetic in the quiet realization of her loneliness. "You're a liar," said Shorty hotly. "You didn't git out o' the regiment because it stole niggers. That's only a pretend. The rear is full o' fellers like you who pretend to be sore on the nigger question, as an excuse for not going to the front. You sneaked out o' every fight the regiment went into. You got out of the regiment because it was too fond of doin' its duty." His volubility excited that of the "Captain," who related how he had been doing a prosperous business running a bar on a Lower Mississippi River boat, until Abolition fanaticism brought on the war; that he had then started a "grocery" in Jeffersonville, which the Provost-Marshal had wickedly suppressed, and now he was joining with others of his oppressed and patriotic fellow-citizens to stop the cruel and unnatural struggle against their brethren of the South. As he reached the top of the bank a yell and a volley came from the other side of the creek. Shorty joined him at once, bringing the two boys on the engine with him. "I'll look out for that." "That is," Dr. Haenlingen said, "fools like you." Rogier opened his mouth, but the old woman gave him no chance. "People who think psychology is a game, or at any rate a study that applies only to other people, never to them. People who want to subject others to the disciplines of psychology, but not themselves." "There are spots the steel's never covered," he said. "You can tunnel through if you're lucky." A pause.
