A DEVELOPMENT OF MATHEMATICAL PROBLEM-SOLVING ABILITY IN THE APPLICATION OF DERIVATIVES USING THE SSCS MODEL COMBINED WITH MATHEMATICAL PROBLEM-SOLVING PROCESSES FOR UNDERGRADUATE STUDENTS AT DHONBURI RAJABHAT UNIVERSITY

Abstract

The research's objectives were threefold: 1) to develop an effective learning management plan for teaching the application of derivatives using the SSCS (Study, Solve, Create, and Share) model combined with the mathematical problem-solving process, aiming to meet the standard criteria of 75/75. 2) To compare students' mathematics learning achievement in the application of derivatives after implementing the SSCS model combined with the mathematical problem-solving process against a benchmark of 75% proficiency. 3) To examine students' confidence in solving mathematical problems related to the application of derivatives when instructed using the SSCS model combined with the mathematical problem-solving process. This research sample consisted of 30 students from the Faculty of Education at Thonburi Rajabhat University, selected through simple random sampling.    

The research instruments included: 1) a learning management plan for the application of derivatives, utilizing the SSCS model combined with the mathematical problem-solving process. 2) A mathematics achievement test focused on the application of derivatives. 3) A questionnaire assessing students’ confidence in solving mathematical problems related to the application of derivatives. The data were analyzed using statistical measures such as percentage, mean, standard deviation, and t-test for one sample.

The research findings are as follows: 1) The efficiency of the learning management plan was 76.67/79.33. 2) The students' mathematics learning achievement on the application of derivatives, after using the SSCS model combined with the mathematical problem-solving process, was statistically significantly higher than the 75% criterion at the 0.05 level. 3) The students demonstrated a high level of confidence in solving mathematical problems related to the application of derivatives using the SSCS model combined with the mathematical problem-solving process.
