THE DEVELOPMENT OF MATHEMATICS PROBLEM SOLVING ABILITY OF GRADE 11 STUDENTS USING THE SSCS MODEL WITH BRAINSTORMING TECHNIQUE

Abstract

The objectives of this study were 1) to develop grade 11 students’ mathematics problems solving ability through the SSCS learning management with brainstorming technique so that the students made a mean achievement score of 70% of the full marks or better on mathematics problem solving ability, and that at least 70% of the target group passed the criterion, 2) to enhance the students’ mathematics learning achievement through the SSCS learning management with brainstorming technique so that the students made a mean learning achievement score of 70% of the full marks in mathematics and at least 70% of the target group passed the criterion. The target group consisted of 30 grade-11 students in Wiang Wonggot Wittayakom School under the Office of Secondary Education Service Area 25, during the first semester of the 2018 academic year. The study followed Action Research procedures for data collection which comprised 3 action spirals.  Three categories of research tools were used in the study, i.e. 1) action research tool  consisting of 9 lesson plans basing on the SSCS learning management together with brainstorming technique which took 18 instructional periods to complete, 2) reflection tool consisting of teacher’s teaching behavior observation form, the student studying behavior observation form, learning achievement recording form, student opinions recording form and end-of-spiral quizzes, and 3) evaluation tool consisting of a 5-item essay test on mathematics problems solving ability and a 4-choice objective learning achievement test totaling 20 items. The quantity data were analyzed by using basic statistics of arithmetic mean and percentage while the qualitative data were analyzed by testing content validity.

                    The findings show that:

                        1) The students made a mean achievement score of 40.03 (or 80.07% of the full marks) on mathematics problems solving ability, and 25 students (or 83.33% of the target group) passed the criterion which is higher than the prescribed criterion;

            2) The students made a mean learning achievement core of 14.67 (or 73.35% of the full marks) on mathematics problems solving ability, and 23 students (or 76.67% of the target group) passed the criterion which is higher than the prescribed criterion.
