In the first half of 2020, primary and secondary school teaching was transformed into online teaching in China, and the teaching effects have attracted considerable attention. This article collects relevant data on the effects of online learning among primary and middle school students through questionnaire surveys to study the impact of parents and teachers on learning effects, provide an experience for future online education and improve the quality of online education for primary and secondary school students in the future. Through empirical analysis, this article draws three main conclusions. First, parents improve students’ offline social presence, while teachers or classmates improve their online presence. Both changes have a significant positive impact on students’ subjective learning effects. Second, parents are more helpful with regard to the improvement of students’ objective learning effects. Third, in terms of age, parents have a greater influence on younger students. The innovation of this article is that the object of the study is primary and secondary school students. The article considers not only the role of teachers but also the role of parents, thereby filling gaps in the previous literature. JEL codes: I20, I21, I25
