A Study of Mathematical Problems Solving Ability on Solving Problems with Single-Variable Linear Equations by The SSCS Learning Model with DAPIC Concept of Matthayomsuksa 1 Students

Abstract

            The purposes of the research were to 1) study mathematical problem-solving ability in Solving problems with single-variable linear equations in Matthayomsuksa 1. 2) compare mathematical problem solving ability in Solving problems with single-variable linear equations with the criteria of 70 % by the SSCS learning model with DAPIC concept in Matthayomsuksa 1. and 3) study of satisfaction in Matthayomsuksa 1 towards the SSCS learning model with DAPIC. The sample group used in the research were 34 students Matthayomsuksa 1 of Khetkarnthangsongkroh 5 (Traikarmsittisil) School. The research instruments used were           1) Mathematics lesson plans on Solving problems with single-variable linear equations by the SSCS learning model with DAPIC concept, 2) a mathematical problem - solving ability test, and 3) a satisfaction questionnaire for students with the SSCS learning model with DAPIC concept. Data were statistically analyze by percentage, mean, standard deviation and t-test for one sample.

            The result revealed as follow: 1) students had the mathematical problem - solving ability in 4 aspects: understanding the problem 82.35%, devising a plan 75.53%, carrying out the plan 76.47%, and looking back 79.41%, 2) students mathematical problem - solving ability in Solving problems with single-variable linear equations by the SSCS learning model with DAPIC concept of Matthayomsuksa 1 was higher than the criteria of 70% with statistically significant at the .05 level. and 3) the satisfaction of Matthayomsuksa 1 students towards the SSCS learning model integrated with the DAPIC concept was at the highest level.
