The Effects of Using Inquiry Instruction (7E) Together with STAD Technique on Learning Achievement and Scientific Reasoning Ability of Grade 10 Students at Islamic College of Thailand in Bangkok Metro

Abstract

           The purposes of this research were to (1) compare learning achievement of  grade 10 students at Islamic College of Thailand who learned by using inquiry instruction (7E) together with STAD technique with that of the students who learned by using traditional instruction, (2) compare scientific reasoning ability before and after learning of the students learning by using inquiry instruction (7E)  together with STAD technique, and (3) compare scientific reasoning ability of the students who learned by using inquiry instruction (7E) together with STAD technique with that of the students who learned by using traditional instruction.The research sample was 74 grade 10 students in two intact classrooms in the first semester of the academic year 2020 at Islamic College of Thailand in Bangkok Metropolis. The sample was obtained by cluster random sampling and then randomized. One group was an experimental group of 40 students while the other group was a control group of 34 students. Research instruments were (1) the lesson plans of inquiry (7E) together with STAD technique, (2) a learning achievement test, and (3) a scientific reasoning ability test. The statistics used for data analysis were mean, standard deviation and t-test.The research findings showed that (1) learning achievement of the students learning by using inquiry instruction (7E)  together with STAD technique was significantly higher than that of the students learning by using traditional instruction at the .05 level of statistical significance, (2) scientific reasoning ability of the students after learning by using inquiry instruction (7E)  together with STAD of the students was significantly higher than that of their before learning at the .05 level of statistical significance, and (3) scientific reasoning ability of the students learning by using inquiry instruction (7E)  together with STAD technique was significantly higher than that of the students learning by using traditional instruction at the .05 level of statistical significance.
