The aim of this study was to understand the components that influence the mental models of preservice elementary teachers on the astronomical phenomena of seasons of the year and lunar phases of the month. For this, participants were selected from a university of education. Data was collected from a paper-pencil test and individual interviews with the participants. The results of this study showed that the preservice teachers had apparent synthetic mental models, and that the 'Distance Theory' and 'Occlusion Theory' had the greatest effect on their mental models. Furthermore, it was found that preservice elementary teachers' initial mental models of 'astronomical phenomenon' had their origin in personal belief sets (specific theory) related to 'astronomical phenomenon'. It was on these belief sets that they interpreted their observations and cultural information with the constraints of a naive framework of physics. The structures and possible sources for overcoming these synthetic mental models were also discussed in this paper. Lastly, implications for preservice elementary teacher education were presented.

The purpose of this study is to explore the possibility of qualitative evaluation and applicable models in the evaluation area of educational program. To this end, the concept and characteristics of qualitative evaluation are examined, and grounded theory is selected as a suitable methodology for evaluation, and its characteristics and procedures are described. Because qualitative evaluation focuses on the spontaneous practice elements of the site, it can supplement the quantitative evaluation of the variables set in advance. The researcher presented the theory of qualification as a methodology for qualitative evaluation, aiming to extract the theory explaining the phenomenon among the qualitative methodologies.

The purpose of this study was to develop and evaluate the Marital Equality Education Program for women farmers and their husband. Based on the empirical research result of 980 women farmers as basic study for developing this program, marital equality theory, system theory, strong family perspective, stress coping theory, anger control theory, modified Couple Communication Program, marriage enrichment methods, 7 session program was developed. The contents of every session were Reviewing Marriage Relationships, Coping Role Stress, Marital Equality, Self Expression & Speaking, Understanding Spouse & Listening, Anger Control& Resolving Conflict, and Enhancing Marital Relations. The effectiveness of this program was evaluated by pretest, post test, and follow-up 1 month later through 35 rural couples(women farmers and their husband) and it was analyzed by paired t-test and qualitative evaluation was also investigated. The major results were as follows : This program was effective in improving their self-esteem, marital satisfaction, coping role stress & conflicts, and husband's egalitarian role attitude & practice. The results suggested the program had also Positive impacts on the marital equality and relationships. Future research and practical implications were added.

The current study reported on the continuing relevance of the schema theory for reading as it relates to the field of teaching and SLA, whilst highlighting the inherent limitations affecting individual learners. A relevant study was conducted for this article focusing on the extent to which university teacher trainees of English Education are exposed to second language readings with an adherence towards utilizing prior knowledge and drawing upon schemata to support their comprehension. Results from quantitative and qualitative data measured and collected from two groups of university students respectively, indicated certain advantages to this strategy use in respect of increased understanding, familiarity, and comfort level in SL reading. However, those same results identified existing limitations associated with cultural bias, stereotyping and a tendency to focus on wrong information when activating said schemata. As such, the purpose of this study is to promote awareness of the schema theory as an effective strategy option whilst reinforcing a need to pay heed to the concerns associated with strict reliance upon such theory to aid reading skills. Further discussion of these issues and pedagogical implications has been provided along with both suggested considerations regarding teaching for EFL teachers and evaluators.

Recent national policies National Competency Standards(NCS) to develop teaching-oriented education in the field of industry and learning is taking place. Plan to take advantage of the Internet and multimedia classes, information and communication technology (ICT) for ways to leverage the integration appearing in various forms. The purpose of this study is causal influence on the ARCS motivation theory can determine the basic psychology of human motivation factors and the desires of a typical human nature theory dealing with the psychological needs of interactivity and immersion is learning achievement and learning transfer and to validate the demonstration. By applying information and communication technology sector in the development of learning in information and communication equipment training program modules from a field study conducted at the NCS with a clear empirical and empirical research through the synchronization to the learner and to explore the possibility of generalization.

The main purpose of this research work is to investigate the free vibration of conical shell structures reinforced by graphene platelets (GPLs) and the elastic properties of the nanocomposite are obtained by employing Halpin-Tsai micromechanics model. To this end, a shell model is developed based on Donnell's theory. To solve the problem, the analytical Galerkin method is employed together with beam mode shapes as weighting functions. Due to importance of boundary conditions upon mechanical behavior of nanostructures, the analysis is carried out for different boundary conditions. The effects of boundary conditions, semi vertex angle, porosity distribution and graphene platelets on the response of conical shell structures are explored. The correctness of the obtained results is checked via comparing with existing data in the literature and good agreement is eventuated. The effectiveness and the accuracy of the present approach have been demonstrated and it is shown that the Donnell's shell theory is efficient, robust and accurate in terms of nanocomposite problems.
