The Study of the Effect of Unplugged Coding Leaning Activity on Computational Thinking Skill of Grade 3 Students.

Abstract

The purposes of this study were 1) to study the effect of unplugged coding learning activity on computational thinking skill of Grade 3 Students with an efficiency of 70/70, 2) to compare computational thinking skill after participating in learning activity, and 3) to study the students’ satisfaction of the learning activity. The sample group of this research consisted of 43 students in Grade 3/7, Anubanmahasarakham School in the second semester of the 2021 academic year, the sampling used the Simple random method. The research instruments included 1) a lesson plan, which 12 sub-learning plans for 12 hours, 2) 20 items computational thinking skill multiple-choice test, and 3) 10 items of the satisfaction questionnaire. The statistics used for data analysis were percentage, standard deviation (S.D.), the formula E1/E2 (Efficiency) and The Wilcoxon Test.

            The findings revealed that

1. The efficiency of lesson plan with unplugged coding learning activity or coding learning activities without a computer was 75.69/72.91, reaching the established criteria of 70/70.


2. Students who participated in the learning activity has a higher level of computational thinking skill, at .05 of a significantly statistic level.


3. The satisfaction of students who participated in unplugged coding learning activity to enhance computational thinking skill was at the highest level.
