The development of scientific reasoning skills among matthayomsuksa 1 student’s using a problem-based learning model pertaining to the topic of atmosphere

Abstract

Research objectives for the development of scientific reasoning skills using a problem-based learning model pertaining to the topic of atmosphere among matthayomsuksa 1 students. The research participants consisted of 26 matthayomsuksa 1 students, whom were selected by a purposive sampling method. The sampling was based on three criteria’s, which were as follows. 1) These students were registered for a basic science course within the 2nd semester, of the year 2019 2) The researcher was a classroom teacher 3) The students were volunteering and participating in the research project continually. Research data was collected for the 2nd semester via a science reasoning test, a student learning summary, an observation form for teaching and learning by using problem-based learning, an evaluation form for the learning plan of the problem-based learning model and a reflection on the teaching practices of teachers. Content analysis was used as the main method and statistical analysis was used as a supporting data analysis.

Research results presented from using the problem-based learning model were as follows. There were 26 students that developed the ability to use scientific reasoning and abductive reasoning in the highest level. There were 18 students that developed the ability to use retroductive reasoning in the highest level. There were 19 students that developed the ability to use deductive reasoning in the highest level, and there were 20 students that developed the ability to use inductive reasoning in the highest level.
