The result of unplugged coding learning management in the learning unit Simple Programming and Design on computational thinking skills of Grade 6 students

Abstract

The objectives of this research were: 1) to develop an unplugged learning management plan for the learning unit “Designing and Simple Programming” for Grade 6 students with an efficiency criterion of 75/75. 2) to compare the computational thinking skills of Grade 6 students before and after learning through the unplugged learning management approach against the criterion of 75 percent. 3) to compare the learning achievement in the learning unit “Designing and Simple Programming” with the criterion of 75 percent. The sample group consisted of 21 Grade 6 students enrolled in the first semester of the 2025 academic year at Phonthong Pittaya School, selected through cluster random sampling, using the school as the sampling unit. The research instruments were as follows: 1) Unplugged learning management plans (6 lesson plans) with mean scores ranging from 4.37–4.53 and standard deviations between 0.10–0.11. 2) A computational thinking skill test, consisting of 3 situations with 4 items per situation, totaling 12 items, with a difficulty index (P) ranging from 0.57–0.75, a discrimination index (r) between 0.20–0.33, and a reliability coefficient of 0.93.  3) A learning achievement test for the learning unit “Designing and Simple Programming”, consisting of 30 items, with a difficulty index (P) ranging from 0.57–0.75, a discrimination index (r) between 0.20–0.77, and a reliability coefficient of 0.95. The statistics used for data analysis included percentage, mean, standard deviation (S.D.), and one-sample t-test.
