									     Using biographies of outstanding women
       in computer engineering to dispel false
                 impressions about engineers
                                                                                            Yin Kiong Hoh


    ABSTRACT The author has carried out an activity with 80 teachers to enable them to reconsider
    their perceptions of engineers. This introduced them to 20 outstanding women in computer
    engineering, and raised their awareness of their contributions to engineering and society. The
    results revealed that the activity was effective in countering typical perceptions of engineers. By
    providing detailed information about the personal lives and work experiences, the biographies
    might be useful in countering existing cultural stereotypes of female engineers and initiating
    changes in perceptions needed to narrow the gender gap in engineering.
