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) to compare the impact of incorporating the developed instructional model on computational thinking skills among secondary school students, and 3) assess the level of progress of students computational thinking. 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 were examined through descriptive statistics and wilcoxon signed ranks test analysis. Qualitative data underwent content analysis. The research findings revealed that 1) the instructional model consisted of 4 components: principles of instructional model, learning objectives, instructional procedures and evaluation and assessment. The quality inspection results showed that the teaching style meets the specified criteria at a very good level (mean = 4.49, SD = 0.52), indicating that the developed teaching style is 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 3) students computational thinking of relative change scores were 9.00, which indicated few improvements on them.
