DEVELOPMENT OF LEARNING MANAGEMENT BASED ON INDUCTIVE METHOD TO ENHANCE MATHEMATICAL REASONING ABILITY ON EXPONENT OF MATHAYOMSUKSA 5 STUDENTS

Abstract

The purposes of the research were 1) to develop the inductive lesson plan which encourage the mathematical reasoning based on 70/70 criteria, 2) to compare mathematics learning achievement after learning management based on inductive method with 70 percent criteria, 3) to compare the mathematical reasoning ability after learning management based on inductive method with 70 percent criteria. The samples used in the study were 37 Mathayomsuksa 5 students studied in semester 2, academic year 2020, at Triam Udomsuksa Pattanakan Roiet school, obtained using the Cluster Random Sampling technique.
The research instruments consisted of lesson plans, achievement test, mathematics reasoning test. The statistics used to analyze the data were percentage, mean, standard deviation and
t – test for one sample. The results of the study indicated that: 1) the inductive lesson plan found that its efficiency were 84.21/74.32. It was in the setting criteria 70/70, 2)the mathematics learning achievement after learning management based on inductive method was statistically higher than 70 percent criterion at .05 level, and also 3) the mathematical reasoning ability after learning management based on inductive method was statistically higher than 70 percent criterion at .05 level.
