The effect of the 5e learning model on teaching the concept of proportion of ratio

In this study, the effect of using teaching method based on the 5E learning cycle model on students' academic success in mathematics was investigated. The study was carried out with 55 students studying at S.H Secondary School in the second term of the 2021-2022 academic year. In the research, 7/A and 7/B classes, which are equivalent to each other in terms of success, were determined by drawing lots as the 7/A class as the control group and the 7/B class as the experimental group. While there were 27 students in the control group, the experimental group consisted of 28 students. Lesson were taught to the experimental group with the activities prepared in accordance with the 5E learning model, and to the control group with the activities in the MEB textbook.Experimental model with pretest-posttest control group was used as the model of the research. As a measurement tool, the two-stage ratio-proportion achievement test, which includes open-ended questions and multiple choice questions, was used as a pre-test and post-test. The obtained data were analyzed with SPSS 26.00 statistical program. Mann-Whitney U and Wilcoxon signed-rank tests were used in the analysis of the data. Frequency and percentage distributions of the answers given by the students to each question were determined. When the findings were examined, it was seen that the students' post-test scores were significantly higher than their pre-test scores. According to the results, it was found that the lessons taught with the lesson activities prepared in accordance with the 5E learning cycle model in the teaching of the subject of proportion were significantly more effective than the lessons taught with the activities in the MEB textbook.
