The present study, which was conducted in Timss 2007 framework, aims to examine the effectiveness of teaching critical thinking on students’ academic achievement in mathematics and science. Research design was Semi-experimental. Research sample (With available sampling method) included two classes of third grade students in Eghbal middle school in Baharestan, Tehran, Iran in 2014-15 which were randomly assigned to experimental and control groups. Afterwards, the experimental group received critical thinking teaching for 12 sessions, while the control group received no training during this period. The data were gathered using parallel forms of Timss 2007 study, which were implemented in three periods. The data were analyzed through Analysis of Covariance (ANCOVA), and t-test. Results showed that critical thinking teaching could considerably improve students’ performance in mathematics and science in domains of reasoning and applying; however, no significant relationship was revealed between critical thinking teaching and students’ performance in the domain of knowing. Findings of the follow up test, in addition, indicated a significant decrease in applicants’ scores of experimental group. It can be concluded that critical thinking teaching should be brought into sharper focus in syllabuses of middle schools as its principles could not only resolve students’ problems in academic issues but they also would result in improving performance of students in the domains of mathematics and science.

The purpose of the present study was to apply the Multilevel Structural Equations Modeling (MSEM) in order to investigate the effect of teachers’ and student’ goal-orientation as well as help-seeking on the 7th grade students’ math performance. For this purpose, 550 seventh grade learners selected by two-stage cluster-sampling method completed Megli et al.’s (2000) Goal-orientation Questionnaire, as well as Rian and Pontrich's (1997) help-seeking Questionnaire. Also, teachers responded to Butler’s (2007) questions about goal-orientation. Data were analyzed using Multilevel Structural Equations Modeling. The results showed that goal-orientation had a significant direct effect on academic performance of individuals and the whole class, and the effect of help-seeking on their academic performance was significant as well. Findings also showed a positive and significant relationship between Mastery Goals and Mathematical Performance, and a negative and significant relationship between the Goals of Tendency toward Performance and Avoidance of Performance with students' Mathematical Performance. Also, considering the teacher's orientation, it was disclosed that there is a direct positive relationship between the Mastery Goal and the Functionalism with the Educational Mastery Functions, and between the Function Escaping Goal and Work Avoidance with Functional Teaching Methods. Moreover, teachers with Mastering Goals had positive perceptions of helping out when needed, and teachers who had Functional Goals concerned with the rote learning of assignments The fit for Multilevel Structural Equations Model evaluated as fair enough and students' Goal-orientation explained 22% of Performance Variance while this amount was 28 % for Teachers’ Goal-orientation.

  The purpose of this study was to investigate the mediation role of study habits in the relationship between progressive motivation and self-regulated learning in first-grade students. The research method was descriptive and correlational. The statistical population of this study included all the high school students in the second district of Kerman consisting of 3900 students in the academic year of 2018. According to the Morgan table, 350 students selected through stratified random sampling methods were selected as the sample. To collect the data, Buffard et al. (1994) self-regulation questionnaire, as well as Kazemi's Educational Achievement Motivation (2007) and Pulessani and Sharma (1989) study habit questionnaires were used. According to the results of the study, there is a significant relationship between progressive motivation and self-regulation (p <0.05); a significant relationship between the developmental motivation and the study habits (p <0.05); and between the study habits and the self- regulation (p <0.05). Also, it was found that study habits have a mediator role in the relationship between progress and self-regulation (p <0.05).
