Due to the rapid development of information technology, acquiring computer programming knowledge is growing in prominence, and computational thinking has become a fundamental skill for children. Using the Two-Tier Test-Based Programming Training (T3PT) approach, Hwang and Tung developed an online learning system for beginners and conducted a quasi-experiment to examine the effect of the system on secondary school students’ computer programming learning.
The Two-Tier Test-Based Programming Training consists of two tiers of questions: the first to assesses students’ understanding of the programming concept, and the second to investigate the reasons for students’ choice in the first tier test to detect whether students have misconceptions about the programming. The learning system, based on students’ responses, provides timely precise feedback to students to enhance their understanding of the correct concepts of programming logic.
