Abstract

This research aimed to study the effect of applying SATIT PSU STEM INNOVATION, in which project-based learning which was designed by grade 10th students, it has the effects on the development of an experimental set approach on the problem - solving skills and physics’ learning achievement. Furthermore, the sample was selected from the students of 10th grade at Demonstration School Prince of Songkla University. In the addition, the sample students had been learning for 16 hours. The research instruments consisted of three; the lesson plan which integrated with SATIT PSU STEM INNOVATION as project-based learning; the design of development of experimental set; By the topic “Work and Energy”. And the achievement test of physics subject. Including, problem-solving skills test. The experimental research was conducted by using a single group of students through pretest-posttest design. Thus, the data was analyzed by mean, standard deviation and t-test dependent group. The results had shown as follows: the students who leaned by integrating SATIT PSU STEM INNOVATION project-based learning in the design of the development of an experimental set; By the topic “Work and Energy”, had gained mean score 22.22% of the students who were in primary level, 41.67% of the students who were in the medium level, and 22.22% of the students were in high level and 13.89% of the students were in very high level. Therefore, the students' mean score of the post-test on physics learning achievement and problem- solving skill was higher than the pre-test mean score at the significant level of .01.
