This study aimed to investigate whether Thai high school students’ perceived teacher support could enhance their reading ability through self-efficacy and sense of school belonging. The theoretical foundation of this study included the theory of social-motivational processes and social cognitive theory. Structural equation modeling was used for analysis and validation. The student questionnaire from the Programme for International Student Assessment (PISA) 2018 survey questions regarding teacher support, sense of school belonging, self-efficacy, and reading ability. The sample consisted of the data collected from the Thai students in the PISA2018 survey, with an effective sample size totaling 7968. The research results of the overall model showed that the perceived teacher support of Thai high school students’ had no direct effect on their reading ability, but their perceived teacher support had an indirect effect on reading ability through their self-efficacy and sense of school belonging. From the results can be seen that high school teachers in Thailand, in supporting and encouraging their students in learning, must simultaneously develop their perceived self-efficacy and sense of school belonging. Only thus can there be obvious help to their students’ reading ability.

There are different strategies to analyze teacher and student performance when they interact with each other in class. The most used strategies are direct observation and verbal reports. Even though what is observed or reported depends on theoretical frameworks regarding didactic interactions, these must be related to teacher functions such as supervision, providing feedback, and evaluation of student performance. In this study, instruments for observational recording and verbal reports were developed and validated considering teacher functions and their student performance counterparts to compare the degree of correspondence or divergence between data gathered from both strategies. 135 students enrolled in a science class and their teachers participated. The class was taught in a public high school located in center/south Mexico. Classes were videotaped and the corresponding observational records were analyzed. Two months later, verbal reports were administered to students and teachers. Coincidences and differences that were found revealed that observer-observe interaction is conditioned by social norms. These results were interpreted considering the notion of silence as a communicative element.
