Abstract
The purpose of this study was to develop a science self-efficacy inventory (SSEI) for junior high school students’ science learning. The first draft of SSEI was originated from the relevant paper review and expertise judgment. The factor analysis on the daft SSEI was employed to test its validity on 300 junior high school students from the middle part of Taiwan. The results of this study showed that the SSEI had reasonable coefficient of internal consistency reliability. The final version of inventory contains 24 items including three subscales, the 10 items in the “Level” subscale, the 7 items in the “Generality” subscale and the “Strength” subscale, respectively. The cumulative percentage of variance of this inventory is 82.41%. After applying formal testing and analyzing the results, the Cronbach α value, .91, indicated that this inventory owned its excellent reliability and validity.
