Objective: This research was carried out with the aim of exploration, description and explication of PhD applicants’ and faculty members’ attitudes on the method of the PhD applicants’ selection (semi-focused and non-focused). Method: To do so, a mixed-methods design was used and the data was collocated in two stages from the academics and also the experts in different fields. In qualitative process about 70 professors and students in different majors were individually interviewed in focus groups; open coding method was used in the process of analyzing the qualitative data, then, the concerns and mental stresses of the beneficiaries in this area were identified. In the quantitative part, 500 academics from the universities in Tehran were asked to answer the researcher-made questionnaires and then the questionnaires were analyzed very carefully. Especially in administrative part, the executive priority was given to the qualitative research and analysis of qualitative findings. Discussion: the discussion was carried out based on the findings of qualitative analysis. In each part, for the purpose of comparing, approving or determining the conflicting cases, the findings of quantitative analysis were presented together with the qualitative findings. Results: the results showed that there was a significant difference between the professors’ and students’ attitudes on the selection of PhD applicants in semi-focused method; namely the professors tended to have more share in the process of selecting PhD applicants, while the applicants were in favor of allocating more share to national organization of educational testing (NOET) in the selection process.

In traditional approaches, single-level statistical models were generally used to analyze IEA data. In hierarchical linear models, each level is, however, introduced by its sub-model, and the variables' interrelations are explained in each specified level. The way the variables affect the existent relations in other levels is also determined. The main purpose of this paper is to compare multi-level modeling and single-level analysis techniques and underline the importance of applying the former in analyzing the data extracted from the TIMSS 2007 questionnaires completed by the eighth graders. Due to their nature, the IEA data were analyzed by HLM software as the students were nested within classes, classes within schools, and schools within countries. In the single-level analysis, there was a significant relationship between self- concept, attitude and evaluation at 0.001 level with mathematics achievement (0.48, 0.296 and 0.134, respectively). Furthermore, the results of two-level analysis by one-way ANOVA with random effects showed that these three variables (self-concept, attitude and evaluation) explained 30.10% and 47% of mathematics achievement variance at student and school levels, respectively. The different results of these two analyses demonstrated the importance of using multi-level analyses for nested data like TIMSS. Regarding the nested nature of TIMSS data and the multi-level method used to extract them, the application of multi-level modeling techniques is recommended to obtain more detailed data on the factors influencing the students' achievement.

Background: E-teaching and e-learning as modern methods has had an evolutionary trend during the recent decades. Since e-learning environments are free from time and space, assessment of students' learning is also a challenging problem in such settings. Objective: The objective of the present study was to examine the impact of e-portfolio on attitude, motivation and academic achievement of Khajeh Nasirddin Toosi University's E- Learning Center Students. Method: The research methods was quasi-experimental and statistics population included all the Khajeh Nasirddin Toosi University's e- Learning Center students who were enrolled in computer engineering course in the second semester of 1389-90 academic year . The sample comprised Two classes of data structure courses that were chosen purposively. The two classes had 50 students that due to lack of cooperation of 10 students, the sample size was 40 individuals who were randomly divided into experimental and control groups. At first, of each group, a pre-test was done in same conditions and then experimental group was exposed to the independent variable. In this way that experimental group trained with e-portfolio and control group trained with conventional method during of 2 months of semester. In order to examine the obtained variations, a post-test of the each group was taken at the end of 2 months. Descriptive and inferential statistics were used to analysis the data. Results: Tthe results showed significantly an increased attitude, motivation and academic achievement toward the examination in the experimental groups compared with the control group. Students, who were trained through e-portfolio, had a high motivation, positive attitude toward the examination and high academic achievement respectively. Conclusion: We can suggest the use of e-portfolio in e-learning as one of the modern methods in assessment.

he present research aims to investigate the role of motivational and attitudinal components on math achievement and compile a structured model for first year high school students in Urumiyeh city. The sample group comprised 300 first year high school students in Orumiyeh city. In order to gather data and determine the level of participants' math achievement, their math scores of the first semester was used. In analyzing data, method of analysis route, using LISREL software, the effects of direct and indirect effects and general self-concept variables, father' education level of mathematics, interest in mathematics, parental support and gender stereotyping were discussed. The results showed that the role of self-concept variables, father' education level, parental support and the importance of mathematical on math achievement was meaningful. Further, the self-concept variables and the education of his father's direct progress with mathematical lesson was significant.The other results in this research for index fit and proper research with data was considerable.
