Learning Management by Using 5 Steps Learning Process together with Polya’s Problem-Solving Process for Develop the Mathematical Problem-Solving Ability of Lower Secondary Education Level Grade 7 Students

Abstract

             The objectives of this research were to 1) create and evaluate the propriety of learning management plan on linear equation with one variable topic by using 5 steps learning process together with Polya’s problem-solving process, and 2) study the mathematical problem-solving ability on linear equation with one variable topic by using 5 steps learning process together with Polya’s problem-solving process. This research employed an action research design.. The sample was Grad 7 class with 20 students from Watbuakkrognua School, Saraphi District, Chiang Mai Province, during the second semester of the 2023 academic year. The sample was selected using a cluster sampling method. The research instruments were 1) learning management plan on linear equation with one variable topic by using 5 steps learning process together with Polya’s problem-solving process, 2) assessment form of learning management plan, 3) the subjective test of mathematical problem-solving ability on linear equation with one variable topic, and 4) the process-based assessment form of mathematical problem-solving ability on linear equation with one variable topic. The statistics used to analyze the data were mean, standard deviation, mode and t-test.

             The research results showed that 1) 10 Learning management plans on linear equation with one variable topic by using 5 steps learning process together with Polya’s problem-solving process were rated at the highest level 2) Most students had the mathematical problem-solving ability on linear equation with one variable topic at a very good level and The t-test analysis showed that the post-test scores were significantly higher than the pre-test scores at the 0.01 significance level.
