The Development of Electronic Book in Integer to Enhancing Mathematic Achievement for mathayomsuksa 1 Students at Hinlubsilamongkol School

Abstract

The purposes of this research were to 1) construct and find the effectiveness of mathematic electronic books in integer for mathayomsuksa 1 Students to be effective, as of the standardized criterion 80/80 2) compare the effectiveness of mathematic achievement in Integer for mathayomsuksa 1 Students after using electronic books towards the normal learning. The population used in this research was mathayomsuksa 1 Students at Hinlubsilamongkol School, Nongbualamphu,  semester 1, Academic Year 2023. The subjects were 10 people, selected by purposive sampling. The instruments were 1) the mathematic electronic books in integer 2) lesson plan of using mathematic electronic books in integer and 3) mathematic achievement in integer test with reliability of the test at 0.83. The data were analyzed by means, percentage, standard deviation, and t-test for dependent sample. The research findings revealed that 1) the efficiency of the mathematic electronic books in integer for mathayomsuksa 1 Students was 81.13/81.25 which was higher than the criterion of 80/80 and 2) The achievement posttest scores on the decimal topic were higher than the pretest scores with a statistically significant at the .05
