Abstract: | Classroom teaching is a main frontier of the implementation of new curricular ideas in China. The study reported in this article is concerned with the effectiveness of system of classroom teaching (SCT) in chemistry lessons. According to the Systems Science theory, we took a macroscopic view on the SCT, arguing that SCT is a hierarchy of system, which includes class system, plate system, unit system, and primitive system. In this study, we focused on primitive system of classroom teaching (PrS)—the lowest level in a SCT. Using focus group interviews, this study investigated the variables related to the effectiveness of PrS. We found a total of 21 such variables. To identify the main factors underlying the effectiveness of PrS, we further used exploratory factor analysis and confirmatory factor analysis. We found five main factors: rational use of time, quality of teaching behavior chain, match degree, quality of using resource and technology, and rationality of primitive content. Based on these findings, we constructed an evaluation scale for assessing the effectiveness of primitive system of chemistry classroom teaching. |
