The Influence of Code.org on Computational Thinking and Learning Attitude in Block-Based Programming Education

In recent years, the elementary schools in Macao have increasingly offered programming curriculum. Programming curriculum emphasizes computational thinking, which is the capacity to analyze, design algorithms, and find solutions to programming problems. However, it is not easy to develop students' computational thinking abilities. In addition, students' poor learning attitudes are connected to difficulties in learning programming. Therefore, it is crucial for educators to investigate how to improve students' computational thinking and learning attitudes. This study applied a quasi-experimental research method to a single group and used a pretest-posttest method to measure the influence of using Code.org on computational thinking and learning attitudes. The participants were 20 third-grade students in an elementary school in Macao. The teaching duration is carried out for three weeks, six lessons per week, a total of eighteen lessons, and 40 minutes per lesson. The Programming Computational Thinking Scale (PCTS) and the Attitude Scale of Computer Programming Learning (ASCOPL) were used to evaluate the implementation's effect. After analyzing the questionnaire scores and students' achievements on the Code.org website, it was found that after receiving the Code.org instruction, students were able to complete most of the stage of the Course B curriculum in Code.org, and their computational thinking and learning attitudes have improved significantly.
