The Effect of Learning Management Using SSCS Model Supplemented with LIVEWORKSHEETS on Mathematics Achievement and Mathematics Problem Solving Ability of Mathayom Suksa 3 Students

Abstract

The purposes of this research were to study and compare mathematics learning achievement and ability to solve mathematical problem before and after learning using the SSCS model supplemented with LIVEWORKSHEETS with students learning through normal learning management and compare with 70% criterion using randomized control-group pretest-posttest design. The sample group used in this study were 77 Mathayomsuksa 3 students in the first semester of the academic year 2022. The samples were selected by cluster random sampling. The research instruments were: 1) the SSCS model supplemented with LIVEWORKSHEETS learning management lesson plans; 2) the normal learning management lesson plans; 3) the mathematics learning achievement test with the reliability of 0.92 ; the difficulty level was between 0.44 to 0.72, and the discrimination was between 0.44 to 0.61;and 4) The mathematical problem-solving ability test with the reliability of 0.98, the difficulty level was between 0.73 to 0.75, and the discrimination was between 0.30 to 0.37. The obtained data were analyzed by percentage, means, standard deviation, One-way MANCOVA and One-sample t- test. The results of the research showed that the post-learning scores of the mathematics achievement scores and the mathematical problem-solving ability scores of both the students using the SSCS model supplemented with LIVEWORKSHEETS and those learning with normal learning management were significantly higher. When differences between groups were tested, it was found that using the SSCS model supplemented with LIVEWORKSHEETS, students had higher Mathematics learning achievement and ability to solve mathematical problems than those who received normal learning management and higher than 70% of the criteria.
