The Development of Mathematic Electronic Books in Addition and Subtraction for Prathomsuksa 4th Students, Khehachomchonladkrabang School

Abstract

          The purposes of this research were to (1) construct electronic books and find the efficiency of mathematic electronic books in addition and subtraction for Prathomsuksa 4^th students to be effective, as ofthe standardized criterion 80/80 (2) compare the effectiveness of mathematic achievemnent in addition and subtraction for Prathomsuksa 4^th students after using electronic books and the normal learning. This research is a quasi – experimental research. The sample for research consisted of 70 Prathomsuksa 4^th students at Khehachomchonladkrabang School of 2 classes during semester 1 in the academic year 2022. Selected by sample random sampling from lottery method. Divided into 2 groups, which are the experimental group teaching by using electronic books. Mathematics on addition,subtraction  and the control group teach using normal teaching. Research tools (1) the mathematic electronic books in addition and subtraction (2) lesson plan of using mathematics electronic books in addition and subtraction (3) achievement test The confidence value of the  test was 0.831. The data were analyzed using, Percentage , mean, standard deviation, and t-test independent test samples.
          The research findings revealed that
          1) the efficiency of the mathematics electronic books in addition and subtraction for Prathomsuksa 4^th was 81.60/81.83   which was higher than the criterion of 80/80
          2) the students mathematics achievement in addition and subtraction after using mathematic achievement in addition and subtraction test was significantly higher than the students using the normal learning teaching at the .05 level.
