Abstract

This research aimed to study the development of mathematical concepts on two-dimensional and three-dimensional geometry for 7th grade students by learning activities based on Concrete-Pictorial-Abstract (C-P-A) approach. The participants in this study were thirty-six 7th grade students in an extended opportunity school in Phitsanulok province. The research was conducted in the second semester of the academic year 2018. A mixed methodology that included both qualitative and quantitative methods was used in this research by applying one group posttest only design. The qualitative data was obtained from the assignment during the learning activity and the pictorial style interview form. With this data, the content analysis to classify the understanding levels was employed. Further, the quantitative data was obtained from the mathematical concepts test which was in the multiple choices style. Researchers analyzed the post-test scores by finding the mean, standard deviation, and testing them with statistic test (t-test one sample) to compare test score with criteria score of 70 percent. The results in this study show that most students’ understanding level was in the Complete Understanding group. Thus, teaching by using activities based on Concrete-Pictorial-Abstract (C-P-A) approach can develop 7th grade students’ mathematical concepts on two-dimensional and three-dimensional geometry. Further, the average posttest score were 22.08 with the standard deviation of 3.54, which were equivalent to 73.61 percent and higher than the criteria of 70 percent with statistical significance at the level of .05.
