The Development of Active Learning Activities to Enhance Inductive Reasoning Ability on Surface Area and Volume of Three-Dimentional Geometry for Prathomsuka VI Students

Abstract

This article aimed to (1) develop active learning activities on surface area and volume of three-dimensional geometry that enhance inductive reasoning abilities to be effective according to the 70/70 criteria and (2) study students’ inductive reasoning abilities through active learning activities. The research model was experimental research. The population consisted of Prathomsuka VI students from Silpakorn University Demonstration School, which serves early childhood and primary school levels. The target group consisted of 22 students selected through simple random sampling. The research instruments used for this research consisted of (1) 15 group-based lesson plans on surface area and volume of three-dimensional geometry and (2) three between-studying tests and one posttest. The data were analyzed using E1/E2 efficiency and the binomial test.

The research results were as follows: (1) The developed active learning activities on surface area and volume of three-dimensional geometry with efficiency were equal to 80.24/84.15, which was higher than the criteria, and (2) The Prathomsuka VI students had inductive reasoning ability higher than 70 percent of the full score, with more than 60 percent of the total number of students at the .05 level of significance. The results of this research will be helpful for mathematics teachers in developing active learning activities that will effectively enhance students’ inductive reasoning ability and can be applied to other content areas.
