Learning Achievement Improvement of 1st Grade Students by Using Problem-Based Learning (PBL) on TPACK MODEL

Abstract

The objectives of the research were: 1) to develop the lesson plans for “Weight and Measurement” of Mathematics by using Problem-Based Learning on TPACK MODEL based on the efficiency of the process and the overall result (E1/E2) at the established criteria of 75/75; 2) to compare the students’ learning achievement in “Weight and Measurement” of the 1st grade students before and after by using Problem-Based Learning on TPACK MODEL; 3) to study the students’ satisfaction with Problem-Based Learning on TPACK MODEL. The research samples were thirty-five 1st grade students of class 1 in the 1st semester of the academic year 2020 at Sanambin School in Khon Kaen Province. They were selected by purposive sampling. The instruments used in this study were lesson plans, an achievement test, and a questionnaire on students’ satisfaction. The statistics used for analyzing the collected data were mean, standard deviation, percentage, and gain score. The research results showed that 1) the average efficiency of the lesson plans for “Weight and Measurement” by using Problem-Based Learning on TPACK MODEL with exercises was 85.54/78.71, which was higher than theestablished criteria. 2) The mean score of the 1st grade students for “Weight and Measurement” of Mathematics after using Problem-Based Learning on TPACK MODEL was significantly higher than that of before using the Problem-Based Learning Model. 3) The overall satisfaction of the students with the Problem-Based Learning on TPACK MODEL for “Weight and Measurement was at a high level.
