class structure

The purpose of this study was to predict the students' boredom in social studies based on the variables of classroom structure, teaching quality and support Affective of the teacher. The statistical population of this study was all 9th grade high school students in Shiraz, in the academic year 1395-96. A sample of 379 people was selected by random cluster sampling. To collect the required data, the questionnaire was used for the study of academic boredom (Pekrun et al., 2002 and 2005), the quality of teaching by Cyriakides et al. (2000), Affective support of teacher Sakiz (2007) and the classroom structure of Eliot and Charch (2001). Data analysis was performed using appropriate statistical tests at descriptive and inferential levels. The results showed that the dimensions of class structure (task, Authority and Harsh in Evaluation) were able to predict academic boredom, and there was a negative and significant relationship between these dimensions and academic boredom of students in social studies lessons. On the other hand, the dimension focus evaluation ability to predict students' boredom was not a social studies lesson. Other findings indicated that there is a negative and significant relationship between the quality of teaching and affective support of the teacher to the students' academic boredom in the social studies lesson and the ability to predict academic boredom.

The aim of this study was to analyze multilevel of student, classroom, and school factors on students' critical thinking. 974 students of high school of Tehran participated in research. The variables selected from three levels of students (basic psychological needs and the need for cognition) of the class (support for autonomy, perceived structure) and school (school culture). A hierarchical linear model was used to analyses data. The results showed that there was a significant relationship at the student level, the variables required for autonomy, need for competence, need for communication and the need for cognition and At the level of the class, perceived structure and support for perceived autonomy had a significant relationship with the components of analysis, curiosity and truth-seeking, tend to be critical thinking. At the school level, teacher-student relationships had a significant relationship with the analytic, curiosity and student relationships with each other and normative expectations. In sum, the findings emphasized the role of student-level factors (basic psychological needs and the need for cognition), the level of class (support for autonomy, perceived structure) and the level of school (school culture) in influencing critical thinking of students.

The present study investigated the mediating role of academic burnout in the relationship between class structure and students’ adjustment to university. Participants were 320 university students (161 women, 159 men) from Shiraz University who were selected by random multistage cluster sampling method. To study the research variables, each participant completed the Class Structure Questionnaire (Elliot & Church, 2001), Adjustment Questionnaire (Baker & Siryak, 1984) and Academic Burnout Scale (Schaufeli, et al., 2002). Reliability of research instruments were determined by Cronbach's alpha coefficient and validity were determined by internal consistency. To analysis data, were used structural equation modeling by AMOS. The result showed that the relationship of class structure with adjustment and academic burnout is significant. Also the academic burnout played a mediating role in the relationship between some aspects of class structure and adjustment.
