The Results of Learning Management Using the CIPPA Model with Decimal Skill Exercises to Promote Mathematical Problem-Solving and Analytical Thinking Skills of Grade 5 Students at Anubanmaechai School

Abstract

This research article aimed to: 1) develop a learning management plan using the CIPPA Model combined with decimal skill exercises to enhance mathematical problem-solving and analytical thinking skills of Grade 5 students at Anubanmaechai School; 2) compare students’ mathematical problem-solving skills before and after learning with the CIPPA Model; and 3) examine students’ satisfaction toward the CIPPA-based learning. The research employed a quantitative approach, using the CIPPA Model framework by (Tithsana Khammani, 2012). The target group consisted of 13 Grade 5 students from Anubanmaechai School selected by purposive sampling. The research instruments consists of 1) eleven CIPPA-based lesson plans 2) decimal skill exercises 3) a 20-item pre- and post-test on decimals and 4) a 20-item student satisfaction questionnaire. The data were analyzed using Relative Gain Score to compare pre-test and post-test scores, and the mean was used to assess the overall performance. The findings revealed that: 1) students demonstrated high-level development in mathematical problem-solving skills after learning through the CIPPA Model; 2) post-test scores were significantly higher than pre-test scores; and 3) students’ satisfaction toward the CIPPA-based instruction was at the highest level (mean = 4.88) across all items.
