“…Appendix A shows the questions used in the analysis, with their associated variables (factors) and values. These questions targeted factors shown in prior research to be predictive of achievement in undergraduate CS programs, such as math background (Cafolla, 1987;Clement et al, 1986;Jagacinski et al, 1988;Lai & Repman, 1996), prior computing experience (Byrne & Lyons, 2001;Taylor & Mounfield, 1989), home and school access to computers (Jones, 1987, cited in Bunderson & Christensen, 1995Foorman et al, 1985, cited in Bunderson & Christensen, 1995, motivation (Charlton & Birkett, 1999), confidence in one's computer ability and the perception that one's confidence is backed by good performance (Charlton & Birkett, 1999;Jagacinski et al, 1988;Volet & Styles, 1992), and encouragement from mentors and role models (Falk et al, 2000). The background survey also included questions aimed at exploring the influence of parental encouragement on achievement and persistence.…”
