Development of Dynamic Mathematics Software-Assisted Instructional Media with Inductive Approach Instruction to Enhance Mathematical Reasoning Ability of Grade 8 Students on Exponents

Abstract

The objectives of this research were: 1) to develop Dynamic Mathematics Software-Assisted Instructional Media using Inductive Approach Instruction at a high level; 2) to compare pre-test and post-test scores after using the media; 3) to study the effects of the media on students’ mathematical reasoning abilities; and 4) to investigate student satisfaction toward the media. The sample consisted of 40 Grade 8 students at a high school in Nakhon Nayok Province during the second semester of the 2024 academic year, selected via cluster random sampling. The research instruments included: 1) the Dynamic Mathematics Software-Assisted Instructional Media using Inductive Approach Instruction; 2) inductive instructional plans; 3) an achievement test; 4) a mathematical reasoning ability test; and 5) a satisfaction questionnaire. Data were analyzed using mean, standard deviation, and t-test for dependent.

The research result revealed that

1) The quality of Dynamic Mathematics Software-Assisted Instructional Media with Inductive Instruction was at a high level.

2) students’ post-test achievement scores were significantly higher than their pre-test scores at the .05 level

3) students’ post-learning mathematical reasoning ability scores after learning by using Dynamic Mathematics Software-Assisted Instructional Media with Inductive Instruction were significantly higher than their pre-learning score at the .05 level.

4) the satisfaction of the students towards Dynamic Mathematics Software-Assisted Instructional Media with Inductive Instruction was at a high level.
