In the first part of this article, the principles of functioning of the solid acid catalysts, their nature and preparation
of a few types were described. In this part, some practical examples of such catalysts employed in the synthesis of several
organic compounds are presented, which illustrate the extent to which catalysts help reduce pollution, cut costs of production,
etc., that are important principles of Green Chemistry.

The interest towards research on learning games is continuously growing, however, the integration of games in teaching is still a somewhat unexplored area of study. In this qualitative literature review, we were interested in the pedagogical foundations that underpin empirical studies and especially in the teacher’s role/activities regarding the use of games in education. The data collection method was based on the systematic literature review models. The data consisted of 35 articles that were coded by using interpretive approach. The results indicate that the teacher’s role was pedagogically active in 21 articles. The teacher’s pedagogical activities became evident in various game-based learning processes: in planning, in orientation, during the gaming, and after the game-play sessions. 相似文献

Teachers cross boundaries when they collaborate with out-of-school partners to provide more authentic learning experiences for students. Using the framework of boundary crossing, the study draws on interview data from schools and their out-of-school partners to examine the research question of how the research participants viewed the beginning of their inter-professional pedagogical collaboration. We use this term because in the context of primary and secondary education contexts mere inter-professional collaboration has usually referred to activities aimed, for example, at addressing children’s social exclusion. The starting point for inter-professional pedagogical collaboration can be seen through the identification of boundaries and boundary crossing. Using theory-based analysis to categorise the interview data, inter-professional pedagogical collaboration became evident in terms of (1) shared pedagogical knowledge, (2) finding roles in new situations and contexts, and (3) resources for collaboration. Recognising these can help schools respond to the needs of twenty-first century learning. 相似文献

ABSTRACT This qualitative metasynthesis investigated students’ meaningful learning experiences amid andragogical teacher education programmes. The programmes catered to the specific learning needs of adult students in the context of university-based teacher education. This study aimed to provide a wider picture of the frames of students’ meaningful learning in andragogical teacher education programmes. The findings revealed three major learning worlds of adult students’ meaningful learning, which formed a common system widening from the professional awakening to the transformative community and agency in society. Based on the findings, this study argues that in andragogical teacher education, which emphasises collaboration and networking in accordance with the current trend in higher education, teacher students may become empowered participants and active agents in society. The findings can be used in planning curricula, and developing programmes of higher education in general and teacher education in particular. 相似文献

The present study analyses Finnish higher education steering system, management by results, from the perspective of higher education institutions. We ask what happens inside a higher education institution, called here the “Campus University”, during the actual negotiations related to the national steering system. We analyse not only the management by results as a steering system but pay close attention to the social space created by this managerial fad. The social space of the negotiations is constructed by different kinds of unofficial elements of social interaction; the physical space, the expected behaviour of the negotiators, the seating arrangements, the coffee servings, and the “small talk”. These elements of interaction are part of the polity of the negotiations and they are controlled by the chairperson of the negotiations. They form the modes of the social space of these negotiations. Therefore, the social space of the negotiations not only supports the hierarchical character of the ritual, but also makes it natural for the Rector to use power to allocate resources because s/he represents the institution. The analysis is based on qualitative and ethnographic methods of research. 相似文献
