The aim of the present study was identifying cognitive subgroups of mathematical disability using model- based clustering in a clinical sample. Participants were 41 mathematical disabled students studying in third, fourth, and fifth grades with mean age of 9.93 years and age standard deviation of 1.11 years (13.33 months) that received special education as learning disables in the centers of learning disabilities treatment of education organization. Utilizing a battery of paper and pencil and computerized tests and tasks, the researchers assessed participants individually during two sessions. Model- based data clustering revealed four distinct clusters of students that their statistical and empirical validity was confirmed: symbolic processing deficit (31.1 percent), visuo-spatial deficit (26.8 percent), executive functions and processing speed deficit (26.8 percent), non-symbolic processing deficit (12.2 percent). These results have implications for presenting positive definitions of mathematical learning disability and are able to motivate future researches for preparing interventions appropriate to each subgroups.

The purpose of this study is to design a multimedia instruction based on the Sweller's Cognitive Load Theory and its impact on the engagement, and transfer of learning Math subject in the 3rd grade students of elementary school. The quasi pre-, post-test, with control group were used in this research. The statistical population were all of 3rd grade students of elementary school in Chaipareh (502 students) in 1396-1397 school year. According to the cluster sampling method two classes from two schools and 15 students from each class were selected randomly. These two groups, in its own, were also randomly assigned to experimental and control groups. The data were collected using of the academicl engagement questionnaire of Shufley & Becker (2006), and the test of transfer of learning in case of the Math (designed by the researcher). Analyzing hypotheses with MANCOVA and t test indicated that the teaching basis of a multimedia instruction based on the Cognitive Load Theory on the students has also a positive effect on the academic engagement including skills, commitment and absorbtion components and transfer of learning of math lesson. according to the findings of this research, it can be concluded that a multimedia instruction based on the Sweller's Cognitive Load Theory is possible to be regarded as one of the efficient ways for expand the level of learners' engagement in classroom learning process and transfers it to a newer and higher educational situations.

The aim of present research has been designing and Validation of appropriate pattern of curriculum of SAMPAD junior schools.This research is combinational design of sequential exploratory in type of toolmaking (instrument- making), which in the quality part was used of multiple case study and histological analytical approach , and in the quantity part was used of descriptive method of scrolling. in the quality part, authorities and specialists were interviewed deeply and half structurally, by guided sampeling approach and benchmark sampling method, and for tool validation and present patern, in the quality part, 106 preforming and educational agents of SAMPAd junior schools of fars were chosen by stratified random sampeling and the assured questionnaire consists of 127 items wascompleted. For analyzing the quality data, the thematic analysis was usedand in the quantity part, confirmatory factor analysis was used. the results of analysis of elements showed that the items of materials and educational sources, teaching and learning strategies, learner activity and grouping of learner are the most .

The present research was conducted with the general purpose of designing an educational brand promotion model at Payame Noor University. The Delphi method and exploratory analysis were selected as the research method. The population and the statistical sample were 32 faculty members of Payame Noor University. The research instrument consisted of earn comments of faculty member's questionnaire, which was developed in three different stages according to the nature of the Delphi method. Bartlett, Friedman, and KMO tests were used to investigate the identified factors in the literature of the research. After applying the above tests and rotating matrix among 79 factors, only 50 factors were classified into six categories  including physical space, field of study, teaching methods, curriculum planning, faculty members, educational content, and as Educational brand promotion model was presented at Payam Noor University. Finally, applied suggestions were presented in order to operationalize the resulting model.

The aim of this study to investigate the relationship between approaches to learning (surface and deep approaches) and educational-personal experiences. Population of the study included students majoring at human sciences and analytical sciences at university of Isfahan, from among which 320 senior students were selected through cluster sampling. Instruments in this study were two questionnaires, i.e., The Revised Two Factor Study Process Questionnaire (R-SPQ-2F), which was used to measure approaches to learning among participants, and Personal and Educational Development Inventory (PEDI) which measured course experiences. A multi-group structural equation model (SEM) examining approaches to learning effects on educational-personal experiences by university majoring. The results indicated there was a significant positive relationship between deep approaches to learning (deep strategies and motivation) and student’s course experience among students majoring at human sciences and analytical sciences (P<0/01); thus, it was concluded that approaches to learning affected educational-personal experiences. One other finding in this study revealed there was a significant negative relationship between surface approaches to learning (surface strategies and motivation) and student’s educational-personal experiences among students majoring at analytical sciences (P<0/01). While, in students majoring at human sciences, there was a significant negative relationship between surface motivation to learning and student’s cognitive development ( ) and surface strategy and cognitive development ( ), but there was not significant relationships among the other aspect of surface approaches to learning and educational-personal experiences.

The aim of this study assesses training needs based on DACUM method and educational standard of ISO 10015. The study population that consist of all engineers of Petrochemical Industries Design and Engineering Company project were studied on 103 persons by Census and purposeful way. The research tools consisted of two questionnaires. The first questionnaire based on the standard requirements of  ISO 10015 and the second questionnaire based on DACUM method and opinion of project expert engineers, qualifications and competencies in three dimensions like knowledge, attitude and skills are developed and collected after the validity and reliability. This study as functional goal and combined method include both section,qualitative and quantitative. The results show that between current and desirable situation of training needs assessment that it based on ISO 10015 from the perspective of project engineers there is a significant difference and documenting and determining the required standards to identify required competencies for each job has the highest priority. Also the results show that by Dacum method, engineers of design and petrochemical engineering company project have six main task and thirty sub-task. Review the training needs of engineers in three dimensions as knowledge, skills and attitude, according to DACUM method shows that there are significant differences between the current and desired situation and also the findings showed that in the knowledge dimention, understanding and knowledge management component and in the skills dimention, mastering principles and techniques of negotiation component, in the attitude dimention, flexibility component has the highest priority, which will be considered as the most important educational needs of project’s engineers.
