The purpose of this study has been to review the changes in the role of demographic and personality variables of mathematics teachers in predicting the mathematical progress of eighth-grade students in Iran and has analyzed the trend of these variables in four international studies. For this purpose, we examine the data from 21434 eighth graders and 877 math teachers who had participated in four TIMSS studies(2003, 2007, 2011, and 2015). Among the educational variables influencing the educational development of 10 variables including gender, age, history of teaching, the degree, major, teaching hours, job satisfaction, confidence, interaction with other teachers and teaching method using statistical methods of Pearson correlation coefficient and multiple regression analysis were investigated. The findings related to the demographic variables showed that the students ' mathematical performance changes were almost consonant with the changes of age, history of teaching, and teaching hours in both groups of male and female teachers. This coordination was not similar about the major and academic degrees. The results of multivariate regression showed that the students ' mathematical development was explained by a set of demographic and personality variables. Among these variables, teaching history and self - confidence of the teachers played the most important role in explaining the students ' progress, and the variables of the degree of education and gender in this basis did not contribute to the explanation of the students ' math’s progress.

Purpose: This research was done to investigate the effect of life syllabus and web-based language learning on the vocabulary improvement of the participants of the study and to seek the attitudes of the learners on the use of web-based approach in language class based on life syllabus. Methodology: Michigan test (version1997) was presented and students were divided into one experimental group who learned their course vocabularies making use of free vocabulary learning sites of IELTS English language learning site every day for 8 weeks based on life issues and one control group who received ordinary classroom instructions each session. Findings: The result appeared to manifest that learners’ perception improved by incorporating web based instruction in language learning classroom based on life syllabus. The findings indicated a significant difference between the experimental and control groups with regard to their vocabulary knowledge. Web-based language teaching instruction enhanced EFL learners' vocabulary knowledge. As Life Syllabus proved to be useful with Iranian EFL learners, EFL teachers also can adopt the technique in their classes to advance their students' language learning and improve their memory.
