The Effect of Instructional Model using Project-Based Learning with Graphic Organizers to Enhance for Secondary Students’ Computational Thinking

Abstract

The objectives of this research were to: 1) compare the computational thinking skills of the sample groups between pre-learning and post-learning through the instructional model using project-based learning with graphic organizers to enhance computational thinking skills for secondary school students; 2) observe students' participation behavior; 3) evaluate students' project performance; 4) evaluate the quality of students' projects; 5) evaluate self-assessment of their computational thinking skills; and 6) study students’ satisfaction and teachers' opinions regarding the developed instructional model. The study employed a research-and-development model. The research employs a simple random sampling method. The tools used in the research include: 1) the instructional package according to the developed instructional model; 2) a computational thinking skills assessment form; 3) a participation behavior observation form; 4) a project performance evaluation form; 5) a project quality assessment form; 6) a self-assessment form for computational thinking skills; 7) a student satisfaction questionnaire; and 8) a relevant instructor interview form. Statistics used in data analysis were mean, standard deviation (SD), mean percentage (%), and t-test.

It was found that 1) the computational thinking skills of students learning with the instructional model after learning were higher than before learning; it was statistically significant at the.05 level; and 2) participation behavior in student project development, it was at a very good level; 3) students' project performance was at a good level very good; 4) the assessment of the quality of students' projects were at a very good level; 5) students self-assessed their computational thinking skills at a good and excellent level in all four components, more than 80 percent; 6) the results from a questionnaire revealed that the students were satisfied at the highest level with instructional model; and 7) opinions of related teachers, it can be concluded that the instructional model using project-based learning with graphic organizer to enhance computational thinking skills for secondary school students.
