Development of an assessment tool for positive experiences about science (PES)

This research aimed to develop an assessment tool for students' Positive Experiences about Science (PES). A preliminary version of PSE was developed through literature review, consisting of academic emotion, self-concept, learning motivation, career aspiration, and attitude in science. A pilot test was conducted with 198 students and a main test was then conducted with 1,841 students. The PES test found to have good validity and reliability. There were significant (p<.05) differences by students' grade, gender, and participation in science activities.
