Abstract

The purposes of this study were: 1) to study Mathayomsuksa III students’ conceptual knowledge on circle after being taught through the conjecturing and proving method with GeoGebra program; and 2) to study Mathayomsuksa III students’ proof abilities on circle after being taught through conjecturing and proving method with GeoGebra program. The sample group was 40 Mathayomsuksa III students of Prasarnmit Demonstration School (Secondary), in the second semester of 2018 academic year. The research instruments of this study were: 1) 6 lesson plans that allowed students to learn the topic via conjecturing and proving method with GeoGebra program; and 2) The conceptual knowledge and proof abilities test on the topic of circle.


The research findings revealed that: 1) after being taught by conjecturing and proving method with GeoGebra program, over 60% of the sample group had conceptual knowledge on circle score that satisfied the criteria at a significant level of .05; and 2) after being taught by conjecturing and proving method with GeoGebra program, over 60% of the sample group had proof abilities on circle score that satisfied the criteria at a significant level of .05.
