Developing a Computational Thinking Application for the Computing Science Subject for 10th Grade Students at Rayongwittayakom School

Abstract

       This research aimed (1) to develop a computational thinking application for computing science subject for grade 10^th students, (2) to test efficiency of the computational thinking application for computing science subject in accordance with E1/E2 criteria, (3) to assess students’ computational thinking skills from using the computational thinking application for computing science subject, and (4) to study students’ learning progress through the use of the computational thinking application for computing science subject. The research sample included 40 grade 10^th students from one structured classroom focusing on science-mathematics, Rayongwittayakom School, selected by a cluster sampling method. The research instruments included (1) the computational thinking application for computing science subject for grade 10^th students, (2) computational thinking skill measurement in the form of an objective test with a short answer, and (3) pretest and posttest in the form of an objective test with 4 possible answers. Statistics used for data analysis were percentage, mean, standard deviation, effectiveness index, and one sample t-test dependent.  

       The study results revealed that (1) the quality of the content of the computational thinking application for computing science subject for grade 10^th students was at a very good level (=4.81, S.D.=0.24) and the quality of media was at a very good level (=4.83, S.D.=0.18), (2) the efficiency of the computational thinking application for computing science subject in accordance with the E1/E2 criteria was 84.75/84.83, which was higher than the normal criteria of 80/80, (3) the score of the sample’ computational thinking skills was 77.65% which was higher than the criterion of 70%, with statistical significance level of 0.01, and (4) the sample had increased learning progress with the effectiveness index equal to 0.6884 or 68.84%.
