The purpose of the present study is to develop an engineering self-efficacy scale for students. Based on the result of literature review, I developed 79 test items and was administered preparatory test for 111 engineering major university students located in Busan. As a result of factor analysis, major related knowledge efficacy, career expectations efficacy, team activity related efficacy and creativity related efficacy were yielded and 33 items (9 major related knowledge efficacy items 10, career expectations efficacy items 7, team activity related efficacy items 7, creativity related efficacy items) were selected as final items. I conducted main study with selected items for 501 engineering major university students in Busan. Correlation analysis among the subscores of engineering self-efficacy and general self-efficacy scale were conducted for the concurrent validity. After conducting correlated analysis between general self efficacy scale(차정은, 1997), the value between subordinate factors is .34~.66 and the value between overall factors is 69. Through this study, I can identify that component factors between two measurement are correlated.
To identify the item distinction level of engineering self efficacy and to verify average and standard deviation of each item and to verify the difference in upper/lower 25% group, I conducted t-test. In each item, the average engineering self efficacy of upper group was higher than that of lower group. All 33 items show significant difference between two groups. According to the result of distinction level of subordinate factors, major related efficacy, career expectations efficacy, team activity related efficacy and creativity related efficacy show significant differences between groups. Consequently, the items that compose this scale are reliable in item response distribution or item discrimination.
Internal consistency (Cronbach's α)of engineering self efficacy scale is as follows: major related efficacy ,81, career expectations efficacy related efficacy .78, team activity related efficacy .88. creativity related efficacy .82. Internal consistency (Cronbach's α) of the sacle is very high .94. Overall, this engineering self-efficacy shows satisfactory reliability in measuring engineering self efficacy.
Engineering self efficacy scale was proved that this scale is composed of items which have high reliability and validity in terms of statistics. There, this scale can provide concrete and objective materials in measuring engineering self efficacy.
