THE DEVELOPMENT OF CONTEXT-BASED LEARNING ACTIVITIES INTEGRATED WITH GEOGEBRA TO ENHANCE MATHEMATICAL CONNECTION ABILITY FOR GRADE 8 STUDENTS

Abstract

The purposes of this research are 1) to create and explore the effectiveness of learning activities using context-based learning integrated with GeoGebra to promote mathematical connection ability for Mathayomsuksa 2 students according to the 75/75 criteria, 2) to compare students’ mathematical connection ability before and after learning, 3) to compare students’ mathematical connection ability after learning with the 75 percent criterion, and 4) to examine students’ learning outcomes and learning behaviors, and     5) to examine students’ satisfaction toward the learning activities. The sample group was Mathayomsuksa 2 students at Ban Wang Kwan School, Phitsanulok Province, in semester 2 of the academic year 2025. The participants consisted of ten students selected by purposive sampling. The instruments used in this research were learning activities and manuals for context-based learning integrated with GeoGebra, a mathematical connection ability test, and a satisfaction questionnaire. Statistics used in data analysis were percentage, mean, standard deviation, one-sample t-test, dependent t-test, and content analysis.

          The results of this research were as follows: 1) the learning activities had an efficiency value of 78.06/77.78, which met the specified criteria of 75/75.     2) students’ mathematical connection ability after learning was higher than before learning at the .05 level of significance. 3) students’ mathematical connection ability after learning was higher than the 75 percent criterion at the .05 level of significance. 4) students demonstrated all three aspects of mathematical connection ability. 5) students’ satisfaction toward the learning activities was at the highest level.
