One common theme underlying recent reports on science education is that the content of school science and its related pedagogical approaches are not aligned with the interests and needs of both society and the majority of the students. Most students do not find their science classes interesting and motivating. These claims are especially valid regarding those students who, in the future, will probably not embark on a career in science or engineering but will need science and technology personally and functionally as literate citizens. One key problem seems to be that few science programs around the world teach how science is linked to those issues that are relevant to students’ life, environment, and role as a citizen. As a result, many students are unable to participate in societal discussions about science and its related technological applications. This paper discusses the need to incorporate socioscientific ideas into the science curricula more thoroughly. This recommendation is supported by a theoretical rationale from various sources leading to a reflection about common practices in science education in three countries: Israel, Germany, and the USA. The state-of-the-art, potentials, and barriers of effective implementation are discussed.  相似文献

Teacher nominations are often used in school settings to identify gifted children. However, although high intelligence is part of almost all definitions of giftedness, prior research has consistently shown that not all children nominated as gifted by teachers have high intelligence. In order to further understand the characteristics of these students, we herein explore the role of another cognitive construct, namely working memory (WM). In a sample comprising N = 81 fourth graders, both WM and intelligence showed the same predictive value for characterizing teacher-nominated gifted children, pointing to the importance of the thus-far-unattended WM for characterizing these students.  相似文献

This paper presents a cross-level study of German student teachers’ beliefs about teaching and learning chemistry. It covers different stages of their teacher training program. The study is based upon drawings of teaching situations, which were analyzed using an evaluation pattern developed using grounded theory. The qualitative scales analyze beliefs about classroom organization, teaching objectives, and epistemological beliefs. Data were collected from university freshmen, student teachers midway through their university teacher education program, and recently graduated teachers who had just finished their university program and are gaining experience as full-time teachers. The initial results reveal that the freshmen in our study profess very traditional beliefs about teaching and learning (characterized by teacher-centeredness and an understanding of learning as receptive consumption). The other two groups of trainees hold more modern beliefs about teaching and learning, which are in line with modern educational theory. Comparing the latter two groups shows that the student teachers midway through training appear to have the most modern teaching beliefs. Implications for teacher education will be addressed.  相似文献

ABSTRACT

Previously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO2 was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO2 decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present.  相似文献

Based on newly assembled survey data, we analyze which individual characteristics of IT employees are associated with the willingness to participate voluntarily in Open Source Software (OSS) projects. We find that, contrary to common expectations, formal educational attainment is not positively associated with the probability or level of OSS contributions. The group of university dropouts, however, does show a particularly high probability of working on such projects. Furthermore, we obtain the striking and novel finding that work-related OSS activities play an important role in determining voluntary OSS contributions during leisure time. Although one has to be cautious regarding the direction of causality, we interpret this as evidence of career-oriented motives in voluntary OSS contributors. The finding is also reinforced by our more specific analysis of the importance of such motives in determining the actual effort invested in OSS projects.  相似文献

Funding, resource allocation, and performance in higher education systems   总被引:4,自引:0,他引:4  
This article analyzes forms of resourceallocation in university systems and theireffects on performance in institutions ofhigher education. Internationally, highereducation systems differ substantially withregard to research and education fundingsources and to ways that resources areallocated. European universities receive themajority of their funding from public sources,but private funding plays a more important rolein Anglo-American systems of higher education.Many governments use competitive elements inthe process of allocating public funds toinstitutions of higher education. Examplesinclude the implementation of performancemeasures through formula funding, or resourceallocation on the basis of evaluated projectproposals. Corresponding forms ofperformance-based resource allocation can befound within most higher educationinstitutions. This article analyzes how variousforms of funding and resource allocation affectuniversities at the macro-level and individualbehavior at the micro-level. A theoreticalapproach to this problem suggests thatperformance-based funding tends to bring aboutpositive changes but is also a factor inunintended side effects. Forms of resourceallocation influence the behavior of academicsand managers in higher education, particularlytheir levels of activity as well as the kindsof activities they engage in and their ways ofdealing with risks. Empirical analyses partlyconfirm these hypotheses. It can be shown thatchanges in resource allocation have an impacton the level and type of activity academicsconcentrate on but not on the long-term successof universities.  相似文献

Most investigations into the effects of funding changes on higher education systems have been carried out in developed economies. This article focuses on the Thai higher education system, applying theoretical arguments and empirical analyses to the case of a newly industrialising country. One goal of the Thai higher education funding reform is to cut public spending and to stimulate university–industry cooperation as a means to obtain additional university income. This article presents empirical data based on an investigation into the cooperation activities of five Thai universities. The results show that both individuals and organisations react to changes in university funding: university–industry relations are becoming more frequent and are promoted by university administrations. The financial benefits for the universities as well as the technological benefits for the cooperating companies are, however, both very limited.  相似文献
