In Japan, there has been an increased concern about family and community participation in the childs education. Traditionally, the role of parents and community in Japan has been one of support and less one of active involvement in school learning. Since the government commenced education reforms in the last quarter of the 20th century, a more active role for parents and the community in education has been encouraged. These reforms have been inspired by the need to tackle various problems that had arisen, such as the perceived harmful elements of societys preoccupation with academic achievement and the problematic behavior of young people. In this paper, the following issues are examined: (1) education policy and reform measures with regard to parent and community involvement in the childs education; (2) the state of parent and community involvement at the eve of the 20th century.  相似文献

Russian higher engineering education is undergoing radical reform caused by the new political and economic situation in Russia. The aim of the reform is to develop a flexible system of engineering education under market economy conditions, considering customer interests and international tendencies in engineering education. The major concepts and principles of a complex system for assessing and monitoring the quality of engineering education are outlined.  相似文献

This study analyses a corpus of argumentative compositions in order to isolate the features of organization pertinent to this genre of writing. A further aim is to compare compositions written by “A” level students and English teachers in order to highlight specific shortcomings of the former. Despite using more cohesive devices and an overabundance of lexical repetition, student writing is less coherent. This is largely because of a lack of global links (between paragraphs), and an inability to properly utilize given information in structuring non-narrative writing. Finally, student writing suffers from presentation of content at the expense of discussion of issue and weighing of views.  相似文献

This study explored the role of student (e.g., age, language background, gender), home (e.g., parent/caregiver education), and school (e.g., school type, size) socio-demographic factors in students’ school (e.g., in-school arts tuition, arts engagement), home (e.g., parent/caregiver–child arts interaction), and community (e.g., arts attendance, arts tuition) arts participation. The sample comprised 1172 elementary and secondary school students from 15 schools. Findings revealed that student and home socio-demographic factors were the most salient in predicting arts participation across school, home, and community contexts. Age, gender, and prior achievement were the key student socio-demographic factors, while parent/caregiver education and occupation were also associated with students’ arts participation. Implications for practice and intervention pertinent to young people’s arts participation are discussed.  相似文献

This paper reports research on the effects of variations in injection velocity and permeability on the heat transfer and flow through a highly porous medium between two horizontal parallel plates situated at constant distance with constant suction by the upper plate. Due to this type of variation in injection velocity and in permeability the flow becomes three dimensional. The governing equations are solved by adopting complex variable notations to obtain the expressions for the velocity and temperature field. The skin-friction along the main flow direction and rate of heat transfer are discussed with the help of graphs.  相似文献
