One of the important issues in a learning management system is the assessment of the learner’s knowledge level. In basic methods of assessment, questions are simply ticked by the learners, and then automatically scored by machine. In this sort of examinations, two problems may be raised. Firstly, the learner may answer and mark the questions accidentally by guessing the answer without having enough knowledge about the related subject. Secondly, he/she may slip in answering the questions due to his/her inattention, although he/she has enough knowledge about the related subject. In this work, an improved method for knowledge level assessment is presented. In the proposed method learning concepts are modeled based on the hierarchical construct of learning objectives, and the learner’s knowledge model is used to estimate his/her knowledge level. This model is established on the basis of Bayesian networks, and considering the hierarchical construct of learning objectives. To evaluate the proposed method, a set of questions by considering the learning objectives was designed and ordered into different levels of complications. Then these questions were used for assessments. In this work also a new algorithm for updating the nodes in a Bayesian network is introduced. By means of this algorithm the effect of guessing and slipping answers in an assessment is undoubtedly reduced. Finally, by presenting a model for knowledge and use of the hierarchical construct of learning objectives, an effective solution for three above mentioned problems of guessing answers, slipping answers, and the origin of wrong answers have been established.

Traditional approaches and assumptions about the transition of knowledge from teacher to students have been overshadowed by new approaches like "Constructivism". In most Iranian schools, however, the presentation of content is still based on simple transition of concepts from teacher to students. The content of Iranian schools' curriculum is remarkably similar to that of other countries, but Iranian students have a relatively poor performance in comparison with their counterparts in other countries. Thus, paying more attention to new methodologies serves as the best sort of investment in the Ministry of Education. "Conceptual Map" is a new approach to effective teaching-learning based on Constructivism and Ausubel's Meaningful Learning Theory. Conceptual Map can be described as a drawing tool that organizes a set of concepts and meanings in a specific framework based on logical relations. It leads to deep and meaningful learning which is in contrast with rote learning. Conceptual map based curriculum on have many advantages. The present article intends to not only introduce conceptual maps but also elaborate on their application as a teaching-learning strategy, which is in turn an essential stage in course planning, in improving the instruction quality of the chemistry course in Iranian high schools.

: Numerical methods, especially the Finite Element method, are increasingly being used for solving different problems. Due to fact that these methods are approximate, having a good understanding and judgment about the errors and their distribution is very important. Hence education of users of engineering analysis and design software is necessary and inattention to it may result in catastrophe. As regards this issue, the problem of determining the stress intensity factor in a cracked plate under tensile stresses, by using the finite element method together with error estimation and adaptivity, is the subject of this article. For this purpose, an academic FORTRAN code has been developed which is able to estimate the finite element solution error by using the superconvergent patch stress recovery method. In addition, an adaptive solution with remeshings in each step is carried out to improve the quality of the employed finite element mesh. Comparing the obtained results with the analytical solution, as well as the ANSYS commercial software, it is observed that the employed algorithm for error estimation has a better performance and can be used for determination of the stress intensity factor in complex structures with arbitrary cracks.

The aim of this study was to evaluate student’s knowledge on solid waste management in Amirkabir University of Technology (AUT).A questionnaire was designed and 200 undergraduate students of 6 specified Faculties were asked to fill it. The SPSS software was applied for analyzing the collected data of filled questionnaire. The results showed that highest (5.53out of 10)and the lowest(3.66 out of 10)average of knowledge belong to the students of Faculty of Civil and Environmental Engineering and Faculty of Industrial Engineering ,respectively. With reference to the results obtained and in order to improve level of public knowledge of undergraduate students of universities on solid waste management as well as environmental issues, a course of “environmental Science and technology” as a part of every academic curriculum is suggested to be set.

: The lateral load bearing systems of structures are divided to four major groups, which are: moment frames, shear walls, bracings, and combined systems that contain a combination of the previous ones. Nowadays, the combined systems of moment frames and shear walls are utilized in high-rise reinforced concrete structures frequently; therefore, the method of educating these systems is quite significant for postgraduate students and professional engineers. It is worth noting that according to the Iranian code of practice for seismic resistant design and also the Iranian concrete building code, the analysis and design of these combined structures have been complicated because the moment of inertia of cracked sections should be used. In this paper, the different methods of educating the combined shear wall – moment frame structural systems, which are conventional, computerized and a combination of these two methods, have been investigated. The results of statistical studies show that the combination of conventional and computational methods was more successful than the other ones. The only negative point of this method was that the time taken for teaching was improved about two times. Obviously, using the prepared handouts containing some necessary information and examples, decreased this period, and it became about 1.5 times of the other methods.

This paper argues for a more responsive architectural pedagogy that enables future architects to create human environments and that emerges from and responds to societal, cultural, and environmental needs. Human environments are those that enhance, celebrate, and support human activities, those that reflect behavioral and cultural norms defined by society, those that ultimately integrate economy, ecology, and society into systems or are simply those everyday environments. A critical analysis of a number of thematic issues is provided to delineate the gaps between skill-based and knowledge-based pedagogies in the educational process of architecture. The paper provides a number of scenarios that help bridge these gaps while integrating knowledge contents necessary for creating human environments. This mandates a comprehensive understanding of two different but related types of pedagogies in architecture: skill-based and knowledge-based.

Collaborative architecture is considered as a strategic and contentious subject in the success of today’s architecture. As we know, a group does not only act as a set of people, but also goes beyond the sum of people’s abilities in some way. In such design, the building is the gradual expansion in design being beyond a single building, and it contains the social communications and the group of people who deal with design process. The purpose of this article is moving in the course of basic principles of thought in collaborative design. On the basis of such approach, this paper, studies the concept of group and team work in architecture so that recognizing collaborative design steps, we accompanied with a group of students in a student team design and defined their weak and strong points of movement in different steps. According to the importance of participatory architecture in the current age, the impacts of trainings for applying this activity are studied in the students. In order to study the training effects in increasing teamwork quality among the students, Isfahan art university students have been tested. This test has been done as two-hour sketches in groups of five people. This test had been in the research method in Univariant Hypothesis Test and according to the independency of the groups and equivalence of their variance in the society as students’t test (single variable test) for independent groups. These tests included a pre test done in ignorance. The students became familiar with teamwork and then a post test has been taken by the given students after their training course and explaining team work for them, the test results have been studied in this article.
