AN INSTRUCTIONAL MODEL USING ONLINE SIMULATION TOOL FOR EMBEDDED SYSTEM TO ENHANCE COMPUTATIONAL THINKING OF SECONDARY SCHOOL STUDENTS

Abstract

This research objectives aimed to 1) develop an instructional model using online simulation tool for embedded system to enhance computational thinking of secondary school students, 2) compare the impact of implementing the developed instructional model on computational thinking skills among secondary school students, and 3) assess the level of progress of students’ computational thinking after learning though the developed online simulation tool in instructional model using problem-solving methods combined with team, pair, and individual techniques . Sixteen eighth-grade students participated in this study. The research employed various tools, including 1) a semi-structured interview form for experts, 2) an instructional model using online simulation tool for embedded system to enhance computational thinking of secondary school students 3) lesson plans according to the instructional model 4) computational thinking assessment 5) observation form. Quantitative data was analyzed using descriptive statistics and Wilcoxon Signed Ranks Test. Qualitative data was analyzed using content analysis.

The research findings revealed that 1) the instructional model consisted of 4 components: (1) principles of instructional model, (2) learning objectives, (3) instructional procedures and (4) evaluation and assessment. The quality validation results showed that the teaching style met the specified criteria at a very good level (M = 4.49, SD = 0.52), indicating that the developed model was appropriate and suitable for testing, 2) students participated in this instructional model achieved a significantly higher overall scores compared to their scores before the study, at the .05 significance level, and 3) students’ computational thinking of relative change scores were 9.00, indicating development at the initial level.
