The development of learning achievement in mathematics on addition and subtraction problems of grade 4 students using KWDL with Bar Model Techniques

Abstract

The objectives of this research are to 1) improve the mathematics learning achievement in addition and subtraction problems for Grade 4 students using KWDL with bar model techniques, compared to the 70% criterion, 2) compare the mathematics learning achievement before and after using KWDL with bar model techniques, and 3) assess the students' satisfaction after the learning management. The target group for this research consists of 25 Grade 4 students from the first semester of the 2023 academic year at Chumchonyodkaengsongkhro School, selected through purposive sampling. The instruments include six lesson plans, one achievement test with a difficulty index ranging from 0.36 to 0.71, a discrimination index ranging from 0.29 to 0.86, and a reliability score of 0.83, as well as a satisfaction questionnaire consisting of 10 items with a content validity index of 1.00. The statistical methods used for data analysis include mean, standard deviation, percentage, and t-test.
The research findings are as follows:
1) The students' mathematics learning achievement in addition and subtraction problems for Grade 4 students after receiving the learning management had an average score of 14.72, which is significantly higher than the 70% criterion at the .05 level of significance.
2) The students' mathematics learning achievement after using KWDL with bar model techniques was significantly higher than before at the .05 level of significance.
3) The students' satisfaction with the learning management was at the highest level, with an average score of 4.69 and a standard deviation of 0.42.
