Few girls are enrolling to the courses or fields related to computers; enrolled females are preferring to change their study subject, While the graduates choose to work in jobs outside their fields. This phenomen seems to be internationally similar. Some developed countries had already acted on the issue at policy level to prevent the leak. In Turkey, there is a high need of research and discussions to understand the causes of the phenomenen. In this research, we tried to capture the underlying themes of the tendency of not-prefering. We analyzed the related literatüre; interviewed informally 2nd and 3rd year students from Computers and Instructional Department; held a whole-class discussion. Beside students wrote opinion papers on the issue. We analyzed the transcripts as well as papers. The research is resulted with the following themes on this unequal interest in the computer related field: perception underlying socio-cultural development, family expectations, unequal oportunity in use of computers, identifying the field with men because of streotype effect, selfrestriction because of low percieved self-efficacy belief (despite the equal performance), attraction of other fields because of sterotype effect, job requirement of continuous self-development, not longing to spend long hours at a table, worries about becoming asocial, incompatibilty of women characteristic tendencies with the field requirements or the perception of girls not having the innate abilities (as boys) required for the field, boring courses, incompatiblity between female’s learning strategies and instructional strategies, too many family responsibilities comparing to boys, avoidance from jobs which is populated heavily by man, concerns over not being able to find a job in the field. Findings are similar to the themes from other countries.
