The effect of comic-based realistic mathematics approach on students’ learning motivation and conceptual understanding

Comics are reading material that is generally more desirable than textbooks by children, especially teenagers. Based on its characteristics, comics contain stories in the form of pictures and text which is contained in the balloons of text and presented in the panels. If the comic is presented in line with the application of a realistic mathematical approach, especially in learning mathematics, it hopes to create an interesting learning atmosphere for students. However, in this case, the contents of the comic story presented are in the form of learning about integers that are connected with a realistic mathematical approach. Therefore, this study aims to determine the effect of learning with comic-based realistic mathematical approaches on learning motivation and students’ understanding of mathematical concepts. This research is a quasi-experimental study. The population in this study was all the students of class VII of Junior High School of RK Serdang Murni Lubuk Pakam in the Academic Year of 2019/2020. While the sample was the class VII-1 as a control class of 31 students and class VII-2 as an experimental class of 32 students. The instruments in this study were two tests of the ability to understand the mathematical concepts and a learning motivation questionnaire. The normality test uses Liliefors test and the homogeneity test uses the Levene’s test with significance. The data were analyzed using the Manova test. Based on the data analysis, the results show that there was a significant effect of comic-based realistic mathematical approaches on students’ learning motivation and conceptual understanding of integer’s material.

Design research on calculus: Students’ journey in learning definition of definite integral

Some researchers report that students find difficulties in learning definition of definite integration. Therefore, classroom activities designed with design research method to help university students gain better understanding on this topic. In order to support students, realistic mathematics approach was chosen. Series of instructional activities had been designed to reach mathematical goal. Thirty of first year university students in Universitas Negeri Padang were chosen to implement the classroom activities that have been designed. This paper will report students’ journey in learning definition of definite integral in our local instructional theory (LIT). The research shows that students understanding about area, function, inscribed/circumscribed polygon, limit play important role to understand the definition of definite integral. Students need to see those concepts as a unit which cannot be separated to understand the definition of definite integral in a designed classroom activity.
