This paper reflects on the use of didactic material in mathematics classes. It focuses on the mathematical activities of students and the didactical activities of teachers. Its point of departure is a critique of technical-managerial approaches to teaching, learning, and innovation. Based on this critique, fundamental tensions between the development of new didactic material and the cognitive style and daily routines of practising teachers are identified. In the last part of the paper, the concept of mathematical literacy is introduced in order to set the crucial relationship between didactic material for mathematics instruction and the ways in which it is used in the classroom on new and fertile grounds.  相似文献

Knowledge production and scientific research have become increasingly more collaborative and international, particularly in pharmaceuticals. We analyze this tendency in general and tie formation in international research networks on the country level in particular. Based on a unique dataset of scientific publications related to pharmaceutical research and applying social network analysis, we find that both the number of countries and their connectivity increase in almost all disease group specific networks. The cores of the networks consist of high income OECD countries and remain rather stable over time. Using network regression techniques to analyze the network dynamics our results indicate that accumulative advantages based on connectedness and multi-connectivity are positively related to changes in the countries’ collaboration intensity whereas various indicators on similarity between countries do not allow for unambiguous conclusions.  相似文献

The engineering students of today must be educated and trained in the foundations and methods that are necessary for the efficient use of modern technologies and tools, in teamwork and in the procurement and management of information. These goals can only be achieved in a sophisticated course environment that enables the individual work of each student as well as teamwork with data sharing, release procedures, communication, and coordination and which gives access to exercises and exams. All exercises and exams as well as their approval or rejection are done within this environment. The information that is needed for the task is either supplied in the form of lecture material or standards, or it must be found somewhere else on the Web. Within this environment, methods for the application of modern technology and tools are taught and practiced in a “simulated” product development process. This article describes this environment in the mechanical engineering facult y at the Darmstadt University of Technology (http://www.iim.maschinenbau.tu-darmstadt.de).  相似文献

This qualitative study of the social aspects of mainstreaming from the perspective of deaf college students indicates that for some students, social adjustment to college is complicated by experiences of separation and alienation from both deaf and hearing peers. Data were collected through open-ended interviews with deaf students who had little or no previous experience with or exposure to deaf culture or language before their arrival at a mainstream college environment. Feelings of isolation, loneliness, and resentment were most intense during orientation and first year, when alienation from the deaf student community appeared to be caused by lack of sign language skills, unfamiliarity with norms and values of deaf culture, and perceived hostility from deaf peers. Simultaneous experiences of separation from hearing peers appeared to be caused by physical barriers inherent in the classroom, residence hall, and cafeteria environments, as well as by discrimination from hearing peers, who tended to stereotype deaf students. Findings suggest that those involved in the administration and delivery of postsecondary programs for the deaf should investigate the experiences of students who arrive on campus without knowledge of sign language or familiarity with deaf culture and evaluate currently existing programs and services designed to meet these students' needs.  相似文献

Ever since PISA studies have been constantly present in mainstream media, a close relation between academic achievement and economic outcome has been routinely presumed. This essay takes a closer look at some of the most common lines of argument, then goes on to outline a critique of the assumptions underlying the alleged causal relationship between educational achievement and macro-economic performance, bringing out a lack of complexity in said assumptions, as well as (polemically) showing up their conformist bias.  相似文献
