Development of 3D Media in Unplugged Coding Activities to Enhance Step-by-Step Problem-Solving Skills for Grade 1 Students
Main Article Content
Abstract
This research aims to 1) develop 3D media in unplugged coding activities, 2) compare the results between teaching with 3D media and 2D media, and 3) study the satisfaction of students towards 3D media in unplugged coding activities. The sample group for the experiment consists of Grade 1 students from Kasetsart University Laboratory School, Kamphaeng Saen Campus, Educational Research and Development Center, during the second semester of the 2024 academic year. A simple random sampling method was used to divide the group into two, with 30 students in each group. One group used the unplugged coding activity "Flowchart Symbol Board Game" in 3D format, and the other group used the 2D format. The tools used in the experiment include: 1) the unplugged coding activity set, 2) lesson plans, 3) observation forms, 4) problem-solving ability tests, and 5) a satisfaction questionnaire. The statistics used were mean, standard deviation, t-test, and consistency index. The results showed that: 1) the development of 3D media in unplugged coding activities was highly suitable, with a mean score of 4.43, 2) the comparison of teaching with 3D media had a higher mean score (5.60) and standard deviation (2.06) than the 2D media group (mean 5.50, standard deviation 2.15). The T-test revealed no statistically significant difference at the .05 level (t = 0.26, df = 29, p-value = .80), and 3) the satisfaction study showed a high level of satisfaction with a percentage of 56.67%.
