The effect of multiple intelligence based instruction on "Acids and bases" on student achievement in primary education 8th grade science lesson

With this study, the effect of Multiple Intelligence Theory-based teaching on student success was aimed at the subject of "Acids and Bases", which is included in the "Matter and Industry" unit in the Science course of 8 th grade primary school students. The study group of the research consisted of 8 th grade students studying at a public school in the Hekimhan District of Malatya in the 2019-2020 academic year. While forming the experimental and control groups, one of the two branches taking the Science course was taken as the experimental group and the other as the control group. The groups consist of 46 students as the experimental group (n:23) and the control group (n:23). Research data were obtained with a quantitative data collection tool. A multiple-choice achievement test consisting of 20 questions was used as a data collection tool and to measure success. This achievement test was applied as a pre-test at the beginning of the study and as a post-test at the end. While the lessons were taught according to the current program with the control group, the experimental group was taught with activities based on Multiple Intelligence Theory. The lessons of both experimental and control groups were conducted by the researcher as 16 lesson hours. At the end of the application, the change in success was examined by applying the post-test. The data obtained at the end of the study were evaluated using the computer Statistical Package for the Social Sciences (SPSS) 21.0 software. Data were analyzed with the independent sample t-Test and the dependent sample t-Test. As a result of the analysis of the data, it was observed that there was a statistically and practically significant difference in success in favor of the experimental group. These statistical findings determined in the study show that the students' general achievement score and the researcher's in-class observations are compatible.
