The Development of Mathematic Learning Activity on Fraction by Using SSCS Model with Bar Model Technique for Achievement in Mathematics and Problem Solving Abilities of Prathomsuksa 6 Students

Abstract

The purposes of this research were 1) to develop learning activities on fraction  by using SSCS model with bar model technique  2) to study and compare the students mathematics achievement before and after being taught  learning activities by using SSCS model with bar model technique. 3) to study mathematics problem solving ability by using SSCS model with bar model technique.The target groups consisted of 24 Prathomsuksa 6 students who were studying Mathematics in semester 2, of the academic year 2024 at Anubannonghanwittayayon School, Nong Han District, Udonthani Province. The instruments used in this study were divided into 3 parts: 1) 12 lesson plans on learning activities; activities on fraction, 2) students behavior observation The interview questions were also operated at the end of the process. The tests were used at the end of the practice cycle as the students' practice reflection, and 3) the test form of students ability on mathematics problem solving and students mathematics achievement. Data analysis used means, finding percentages, standard deviations.

            The results of this study were shown as follows: 1. Development of mathematics learning activities on fraction by using SSCS model with bar model technique of Prathomsuksa 6 students process could develop the ability of math problem solving and mathematics achievement of students which revealed 4 practical steps: Step 1; Search, Step 2; Slove, Step 3; Create, Step 4; Share 2. The students' ability on mathematics achievement after being taught by mathematics learning activities on fraction by using SSCS model with bar model technique. the mean score before learning was at 20.83 or 68.19 percent and after learning mean score was at 26.21 or 87.36 percent respectively.And 3. Students had ability on mathematics problems solving after being taught by mathematics learning activities on fraction by using SSCS model with bar model technique. The mean score after learning was 17.41 or 87.08 percent. Students had an average score after learning more than 75 percent and the average score after learning was higher than before learning.
