Realistic Mathematics Education (RME) focuses on guided reinvention through which students explore experientially realistic context problems to develop informal problem solving strategies and solutions. This research applied this philosophy of RME to design a differential equation course at a university level. In particular, the course encouraged the students of the course to use numerical methods to solve differential equations. In this context, the purpose of this research was to describe the developmental process in which the students constructed and reinvented Euler algorithm in the class. For the purpose, this paper will present the didactical principle of RME and describe the process of developmental research to investigate the inferential process of students in solving the first order differential equation numerically. Finally, the qualitative analysis of the students' reasoning and use of symbols reveals how the students reinvent Euler algorithm under the didactical principle of guided reinvention. In this research, it has been found that the students developed deep understanding of Euler algorithm in the class. Moreover, it has been shown that the experience of doing mathematics in the course had a positive impact on students' mathematical belief and attitude. These findings imply that the didactical principle of RME can be applied to design university mathematical courses and in general, provide a perspective on how to reform mathematics curriculum at a university level.

BACKGROUND/OBJECTIVE: Competent renal dietitians are crucial for better patient compliance and clinical outcomes, specifically in critical settings. The aim of this study was to develop and evaluate an evidence-based course in renal dietetics for dietitians working in health care systems where dietetic specialization is absent. SUBJECTS/METHODS: Fifteen licensed dietitians working with hemodialysis patients in Lebanon were randomly recruited to participate in the course. The latter was developed by the study's primary investigator, according to evidence-based practice guidelines, and focused on all aspects of renal nutrition. Total course duration was 28 hours spread over a 2 month period. Dietitians' knowledge in renal nutrition was tested pre- and post-training through a 23-item questionnaire; the total score was expressed in percentage (< 60% score indicated insufficient knowledge). Paired-samples t test was used for statistical analysis. RESULTS: Overall knowledge of the dietitians significantly improved post-training and reached satisfactory levels (pre: $38.75{\pm}17.20%$, post: $62.08{\pm}21.85%$). Sub-analysis of the change in the knowledge showed significant and satisfactory improvement only in 3 topics: 1) correct body weight use in calculations, 2) energy estimation method and 3) phosphorus management. Knowledge in the fluid management significantly improved but did not achieve a satisfactory level. CONCLUSION: The course significantly improved dietitians' knowledge in renal nutrition. If adopted as part of the continuing education of dietitians in countries that lack dietetic specializations, it may serve the first step towards improving health care practice.

This study aims to investigate effects of scaffolding on writing apprehension and media literacy in engineering freshmen's synchronous online writing course, and the relationships between the two variables. 'Scaffolding' is in-time support provided by a teacher/tutor or competent peer that enables students to meaningfully gain skills at problem solving process. Also, it is one of the most frequently mentioned concepts in education as well as one of the more necessary teaching strategies in an online writing course. In this study, provided treatments for the experiment were supportive scaffolding for domain-specific knowledge and reflective scaffolding for meta-cognitive knowledge. Participants were 102 engineering undergraduate students, who were assigned to two experimental groups by scaffolding types. A process-based writing course in online learning environment was conducted for 8 weeks. The writing tasks were given according to writing process. The findings were that, firstly, there were statistically significant writing apprehension's reduction and self-expression's improvement through the scaffolding provided in writing class. Secondly, writing apprehension's reduction and self-expression's improvement were significant in supportive scaffolding group. Thirdly, media literacy predicted writing apprehension. The practical implications of these findings are discussed herein, with particular attention on ways for writing apprehension's reduction as well as media literacy's enhancement.

The purpose of this study was to investigate inservice elementary teachers' view and the change of preservice elementary teachers' view on the nature of science by the science education course. The subjects were 386 junior preservice teachers in a National University of Education and 257 inservice teachers working in a metropolitan city. An instrument consisting of fifty eight items were developed on the bases of previous studies. Before entering the course, preservice teachers view was compared by gender with T-test and no significant differences were found except the category 'role of a scientist'. Preservice teachers view was also compared by major with ANOVA and significant differences were found on the categories 'scientific method' and 'scientific law'. After the course, on comparing their view by gender, significant differences were found on the categories 'scientific theory', 'scientific knowledge', and 'scientific law'. The result of ANOVA by major, significant differences were found except the category 'role of a scientist'. Inservice teachers view was compared by gender and major and the differences were no significant, the significant differences, however, were founded in comparing by career and ability.

This paper is concerned with the development case of CEA(Course-Embedded Assessment) design tool for engineering education accreditation operations department for CEA system implemented. Each university or programs are already devoting efforts to build research and CEA system for CEA applied to. In order to effectively apply the CEA studies for each program it is required and particularly, the preferred way to build an operating system is considered a difficult situation of the course unit. Therefore, this case study and to propose a method and procedures required to assessment the design basis for curriculum and program assessment unit in terms of the applicability of CEA, proposes a virtual application results. The information proposed in this case study is determined that could be used in the design for the outcomes and assessment of a variety of programs as one of the steps to build the CEA systems.

This study investigated the effect of the 'Chemistry in everyday life' course for 234 pre-service elementary teachers on their beliefs regarding science teaching efficacy and the nature of science. This study also examined the effect of this particular course by their field (natural science, humanities & social science, and fine arts). The results show that after the semester the pre-service teachers' science teaching efficacy beliefs were enhanced. In particular, their personal science teaching efficacy beliefs were improved across all fields. However, their beliefs regarding the nature of science remained largely unchanged. This study discussed the implications surrounding science courses for pre-service teachers.

Delay, cost overrun and inferior quality in public works are common in Nepal and Cambodia. Almost 90 percent of the civil construction engineers working in the industry were one-degree graduates without appropriate training. The civil engineering education had provided elemental engineering knowledge to the graduates however integrated engineering and management knowledge and skill are essential for efficient infrastructure development. ODA in developing countries had been concentrated in hard infrastructure development without improving the quality of higher education. Integrating ODA to engineering education system would help develop qualified technical manpower and appropriate technology domestically, and improve the efficiency in infrastructure development in developing countries.

This study aims at seeking the effective career guidance and operational plan. We collected data from questionaries to 305 students of vocational school, and 135 students on vocational course for the recognition of and request for vocational home economics curriculum. Collected data were analysed by frequency, percentage, and X(sup)2, and SPSS/PC(sup)+ program are used for the statistical analysis. 1. The main considerations of students in their decision of course were the accessibility of getting a job, or a higher education aptitude, interest, and so on. They made their own decision in choosing their course, relatively were satisfied with their choices. As for the course after graduation they hoped to come by a job related to their major in order to have3 an opportunity for further education, and teachers stood up for the large extent to which their students are satisfied with vocational training by answering that there would be higher possibility of using their major. 2 The results of the investigation into the desirable home economics vocational training in future showed that students of vocational schools desired for the scientific teaching and learning method. Students on vocational curse requested that the educational system should be supported. And new curricula were those for gerontology. interior design, and cookery and bakery.
