Development of Skill Mathematics Training Package on Ratio, Proportion and Percentage for Mathayomsuksa 1, Watthamnawa School Ayutthaya

Abstract

This research’s purposes were developing skill mathematics training package on ratio, proportion, and percentage for mathayomsuksa 1, Watthamnawa School Ayutthaya level to reach 75/75 efficiency standard level, and compare learning achievements between before and after using the developed skill mathematics training package on ratio, proportion and percentage for mathayomsuksa 1, Watthamnawa School Ayutthaya. The sample group for this research was 20 class-3 students of mathayomsuksa 1, from Watthamnawa School, which was selected using cluster random samplings. The tools used for this research were (1) mathematics skill mathematics training package, and (2) learning achievement evaluation tests on ratio, proportion and percentage for mathayomsuksa 1. Statistics used to analyze the collected data were mean, standard deviation, and t-test. The results of the research were (1) the developed skill mathematics training package on ratio, proportion, and percentage for mathayomsuksa 1 were efficient at 79.67/85.50 which was higher than the set standard, and (2) the learning achievements before and after using the developed skill mathematics training package on ratio, proportion and percentage were slightly different with a statistical significance level of 0.01 the latter’s average score was higher than the first’s score.
