Development Mathematical Skills On Addition Subtraction Multiplication And Division Of Fractions By E-Learning For Primary 6 Students In Ban Hin Roi Moei School Under Chaiyaphum Primary Educational Service Area Office 2.

Abstract

The objectives of the study were 1. To Develop Mathematical skills on dition, subtraction, multiplication and division of fractions for Primary 6 students. 2 . To compare the learning achievements between before study and after study by E-Learning for the samples, selected from 5 cases of primary 6 students in Ban Hin Roi Moei school of the Academic Year 2020 under Chaiyaphum Primary Educational Service Area Office 2 by using the Purposive Sampling. The instruments used for gathering data were addition, subtraction, multiplication and division of fraction lessons on development Mathematics skills. The statistics were the mean and the standard deviation. The results of the study were as follows 1) Comparison the learning achievements of the primary 6 students in Ban Hin Roi Moei school under Chaiyaphum Primary Educational Service Area Office 2 on the development Mathematics skills by E-Learning between before study and after study, before study has the mean at 53.6 (x􀴤= 53.6) and the standard deviation at 11.17 (S.D. = 11.17) and after study has the mean at 70.8 (x􀴤 = 70.8) and the standard deviation at 13.97 (S.D. = 13.97). The study was found that the after study achievement was higher. 2) The outcomes of the samples, the primary 6 students in Ban Hin Roi Moei school under Chaiyaphum Primary Educational Service Area Office 2, after study was higher than before study.
