Development of Digital Learning Resources to Improve Geometric Shapes Test Scores of Primary 3 (Grade 3) Students

Abstract

Background and Aims: Currently, third-grade students often face difficulties in understanding geometric shapes, resulting in unsatisfactory test scores. Developing digital learning resources offers a way to enhance learning effectiveness by utilizing interactive media and educational games to stimulate interest and systematically improve understanding. This approach enables students to develop mathematical skills and achieve better academic outcomes effectively. This study aimed to: 1) develop digital learning resources to improve geometric shapes test scores of Primary 3 (Grade 3) students, 2) investigate the students’ achievement after using the digital learning resources to improve geometric shapes test scores of Primary 3 (Grade 3), and 3) study the learning effectiveness index of the digital learning resources to improve geometric shapes test scores of Primary 3 (Grade 3).

Methodology: This research is experimental in nature. The population in the study was Primary 3 (Grade 3) students from 10 schools in the Buengsumphan School group studying in the second semester of the academic year 2023. The sample group was purposively selected from two schools that had the lowest academic test results, including 33 students. The tools included 1) the digital learning resources to improve geometric shapes test scores of Primary 3 (Grade 3) and 2) pre- and post-training tests that consisted of 20 items that had passed the quality test.

Results: The results showed that: 1) the quality of the digital learning resources to improve geometric shapes test scores of Primary 3 (Grade 3) students, as a whole, was at a good level (x ̅ = 4.00, S.D. = 0.59). 2) The comparison of students’ test scores before and after training indicated that the students’ t distribution = 4.78, which was higher than the t-distribution table. 3) The learning effectiveness index was at 0.21—in other words, the sample's knowledge increased by 21.48%. Thus it can be concluded that the digital learning resources could improve the students’ geometric shapes test scores on solving the volume and capacity of rectangular problems at a statistically significant level of .05.

Conclusion: The effective development of digital learning resources significantly enhances students’ learning outcomes, particularly in subjects requiring concrete understanding like geometry. The study found that digital media can significantly increase learning achievement, and the effectiveness index indicates that students have clearly gained more knowledge. Using technology such as educational games and interactive activities helps stimulate interest and makes learning more effective. Therefore, designing digital media tailored to target groups is crucial for enhancing the quality of education in the digital era.
