First, the educational robot system is abstracted to a multibody system and a general dynamic model of the educational robot is constructed by the Newton-Euler method. Then the dynamic model is simplified by a combination of components with fixed connections according to the structural characteristics of the educational robot. Secondly, in order to obtain a high efficiency simulation algorithm, based on the sparse matrix technique, the augmentation algorithm and the direct projective constraint stabilization algorithm are improved. Finally, a numerical example is given. The results show that the model and the fast algorithm are valid and effective. This study lays a dynamic foundation for realizing the simulation platform of the educational robot.展开更多

Current research suggests, however, that as students persist in this activity their situational interest decreases as their ability to exercise consistently at moderate intensity levels increases. In this article I will briefly review the literature citing benefits of exergaming and the role of exergaming in contemporary PE curricula before turning to the question of the place of exergaming in a learning- oriented approach to PE. I will suggest that exergaming, when taught within a situated learning framework, can contribute to student under- standing of the effects of exercise on their bodies and may produce meaningful lessons to assist students to create, monitor, and adapt a fitness plan to participate in life long exercise using a variety of physical activities.

Methods： Participants were 9 elementary physical education （PE） teachers and their 4th- and 5th-grade students （n = 2709 3420）. The students＇ skill competency was assessed with 3 manipulative skills using PE metrics assessment rubrics. The PE teachers＇ levels of QPET were assessed by coding 63 videotaped lessons using the assessing quality teaching rubrics （AQTR）, which consisted of 4 essential dimensions including task design, task presentation, class management, and instructional guidance. Codes were confirmed through inter-rater reliability （82.4%, 84.5%, and 94%）. Data were analyzed through descriptive statistics, multiple R2 regression models, and independent sample t tests. Results： This study indicated that the 4 essential dimensions of QPET were all significant contributors to students＇ manipulative skill competency. These predictors were significantly higher for boys than for girls in soccer and striking skills, while they were significantly higher for girls than for boys in throwing skill competency. Of the 4 essential dimensions of QPET, task presentation played the most significant role in contributing to all 3 skill competencies for both boys and girls. Further, students who experienced high QPET were significantly more skillfully competent than those students who did not have this experience. Conclusion： It was concluded that the QPET practices played a significantly critical role in contributing to students＇ manipulative skill competency.展开更多

Author briefly describes the situation of the many universities of the point of view of education, research, orientation, system of financing and management of the universities. The whole article is based on the author＇s practical experiences. The research objective was to determine how the professional community is looking at private universities and state universities. It was based on the opinion of the quality of graduates and the number of academic staff who are working at state universities These academics have mostly negative view of private universities as well as the knowledge of graduates of these private schools. However, the opinion ofstaffin practice, especially managers in manufacturing companies, trading companies, companies selling services, as well as senior officials in government, are not so negative. By contrast in certain areas such as marketing, business, management, Information and Communication Technology etc., was rather neutral or positive. The politicians were interested about these information with regard to educational reform （reform of universities is still not actual--note the author） and the expected necessary cuts of spending to higher education from the state budget. Unfortunately, the research project due to political changes in 2009 was not completed and obtained only partial results. Despite of this fact the author decided to process the article below Opinions on the topic of public vs. private univeristies were mainly obtained informally from experts from academic area （both public and private）, managers, various specialists, but also from the students themselves. In conclusion man can say that the demand for people who are able to quickly demonstrate their knowledge in practice is still stronger. The title becomes second-rate （unfortunately not quite in the public and state administration）. Very strong demand is the active practice of communication in English （it fulfilles especially private universities） Graduates of technical universities in the classical fields are sought less in the labor market. Very high pressure is developed by state universities to private. This implies a lack of professors and associate professors who can work in full time at private universities which are more flexible and better adapt to labor market requirements.

In this sense, it would be a reasonable idea that an individual should benefit from art education in order to have a complete education, since art is not just creating an aesthetic object or being aware of staying against an aesthetic object. Art means that it occurs in every stage, in every action, in all attitudes and behaviors of human being realized in an aesthetic concern without thinking When the individuals having an art education in primary and secondary education start their education in a higher education program in a faculty or department other than art education, art education loses its continuity. However art education should be continuous and it is of importance in terms of its contribution to this continuity since the studies of art education for the adults out of formal education would support it. The purpose of the current study was to determine the needs of adults and also the support that would be obtained from any kind of educational activities for art education, and to propose some recommendations in this sense展开更多
