Abstract
The main purpose of this study is to compile a computational thinking scale that is suitable for students in the country. Based on the literature review, we have constructed a framework for computing thinking: including abstraction, algorithmic thinking, decomposition, pattern recognition, parallelization, and data processing. We have a total of six constructs oriented to test the thinking abilities of secondary school students; and compare different backgrounds (sex differences in the ability of thinking between students of junior high schools, ages, school districts, and family economic conditions. In this study, subjects of domestic middle school students were selected. After a preliminary test of 215 students, it was decided to use project analysis and factor analysis to determine the factors and indicators of the computational thinking scale, and to complete the preparation of the scale, establish the norm, and Validity study. This study uses the domestic country-centered sample as a tool, and conducts formal surveys targeting domestic students and middle school students through a questionnaire survey method. The questionnaire has collected 532 questionnaires, including paper-based questionnaires. On-line questionnaires were constructed using project analysis, exploratory factor analysis, and confirmatory factor analysis to construct the scale of this study.
The results of this study can be divided into the following three parts: (1) The theoretical scale model and observation data of the “operational thinking scale” proposed by this study have a good fit; (2) the “operational thinking” of this research construction The “scale” has a good construct validity; (3) The “operational thinking scale” constructed by this study has a good construction reliability. Finally, based on the results of the study, the author proposes suggestions for the development of the computational thinking scale, assists teachers in understanding the degree of computing thinking ability of the junior high school students, and provides references for future researchers.
