In this study the effects of different learning environments on the promotion of decision-making competence for the socioscientific issue of genetically modified crops is investigated. The comparison focuses on direct vs. indirect instructions. Therefore on the one hand a sophisticated decision-making strategy was presented to the directly instructed experimental group (1) and had to be applied correctly. On the other hand indirectly instructed students had to invent an appropriate strategy by themselves (2) based on the given information and the structure of the problem context. Group discussions are analysed qualitatively in order (1) to outline how the given strategy was understood and its results were reflected on by the students and (2) to explore the characteristics of invented strategies and their degree of complexity. Results indicate that the direct instruction of complex decision-making strategies may lead to a lack of understanding of the decision process when the given strategy is applied and therefore may cause rejection of the final decision. Indirectly instructed students were able to invent sophisticated decision-making strategies containing compensatory trade-offs. It is concluded that when directly instructing complex decision-making strategies, essential parts of reflection have to be integrated in order to gain greater transparency. Accordingly, empirical evidence has been found to consider indirect instruction as a possible way to foster decision-making strategies for complex socioscientific issues even if compensatory procedures are considered to be necessary.  相似文献

This article reports about our efforts to determine engineering students' competence in mathematics. Our research is embedded in a larger project, KoM@ING–Modeling and developing competence: Integrated IRT based and qualitative studies with a focus on mathematics and its usage in engineering studies, within the program Modeling and Measuring Competencies in Higher Education (KoKoHS). KoKoHS provides the umbrella organization of several research projects addressing the modeling and measuring of competences at the college level. KoM@ING aims to model the role of engineering students' mathematical competences for their studies from both a quantitative and a qualitative perspective.

Here, we report the development of a large-scale instrument assessing engineering freshmen's competence in mathematics by applying Rasch analysis to determine measures for item difficulties and student abilities. Several analyses were performed to provide insights into the measures' reliability and validity. In particular, to examine cognitive validity, we scrutinized students' think-aloud protocols when solving the items to investigate their problem solving abilities as a proxy for item difficulty. Overall, we found first evidence that our instrument is suitable to assess engineering freshmen's competence in mathematics. This instrument may be helpful to conduct further research and to inform those concerned with college organization and policy.  相似文献

Gender effects in large-scale assessments have become an increasingly important research area within and across countries. Yet few studies have linked differences in assessment results of male and female students in higher education to construct-relevant features of the target construct. This paper examines gender effects on students’ economic content knowledge with a focus on construct-relevant explanations. Moreover, we compare gender effects cross-nationally between Germany, Japan, and the United States. To assess economic content knowledge of higher education students, we used translated, adapted, and validated versions of the Test of Understanding in College Economics (TUCE, 4th ed.), an instrument that is commonly used internationally. We found gender effects on test scores in all three countries; effects were larger in Germany and the United States than in Japan. Gender effects were generally more pronounced on the numeracy subscale than on the literacy subscale, that is, male students had a greater edge over female students when items required calculations. In our conclusion, we discuss how numeracy and literacy items may tap different abilities.  相似文献

This paper examines and discusses the views on science and society held among PhD students working in two different industrially and environmentally driven research programmes in the broad area of green chemistry. It is based on thirteen in-depth interviews. The analysis shows three main ways of handling the situation as “post-academic” PhD student: (1) the student sees the PhD work mainly as a job and does not reflect about his/her research or the research funding, (2) the student is satisfied with the post-academic situation, accepts the established innovation policy discourse and is sceptical to traditional academic research, and (3) the student sees collaborative research programmes as a way to get funding, which can be used for secretly done basic research. Most PhD students either emphasise usefulness—in line with the dominating research policy discourse—or they adopt the positivistic view of science as objective and independent of the surrounding society. However, there are only a few signs of “double problematisation”, that is a critical view where both disciplinary-oriented and industry-dependent research are problematised.  相似文献

ABSTRACT

Pollinating animals are profoundly affected by the current loss of biodiversity, a problem that is of concern to science, policy-makers and the public. One possibility to raise awareness for pollinator conservation is education. Unfortunately, insects such as bees are often perceived as frightening creatures; a negative emotion that may hinder successful learning processes. Thus, any educational initiative must conquer this obstacle and promote conservational knowledge. Using a quasi-experimental design, we evaluated the effectiveness of an educational programme using two student-centred learning approaches: One by encountering living honeybees (Apis mellifera) at a beehive (N?=?162), the other by using an eLearning tool connected to a remote beehive (N?=?192). We monitored secondary school students’ environmentally relevant knowledge of bees, their environmental attitudes and their perception of bees in regard to conservation and dangerousness. The results indicate that both approaches lead to the acquisition of conservational knowledge in the short and medium term. Direct experiences with nature are regarded as crucial, but using an eLearning tool in environmental education constitutes an outstanding alternative to acquire knowledge. Adolescents with low ‘green’ attitudes responded positively to the online beehive, and the perceived danger of bees played no role in the learning process.  相似文献

This paper analyses and suggests possible technological innovation strategies in higher educational institutions in Africa. The paper describes management issues in the implementation of eLearning with particular reference to its usage in higher education abroad and in Africa, and also suggests appropriate approaches for technological innovation of higher education in Africa. The major findings of the paper, which are based on three case studies, suggest that eLearning needs to be implemented within a strategically developed framework based on a clear and unified vision and a central educational rationale. The findings further highlight the importance of using a combination of strategies – top–down, bottom–up and inside–out – during the diffusion process to attain coherence, collegiality and ownership. The process of technological transformation is not a smooth translation process but one of dislocations, dilemmas and uncertainties and it is an art to effect change and sustainable technological transformation since people are central to this transformation process.

L'innovation technologique et les stratégies de management pour l'enseignement supérieur en Afrique: L'Harmonisation du réalisme et du l'idéalisme

Cet article analyse et suggére des stratégies d'innovation dans des établissements d'enseignement supérieur en Afrique. Il décrit les problèmes de management qui pose l'introduction du e‐Learning avec une référence particulière pour son usage dans l'enseignement supérieur à l'étranger et en Afrique et suggére les approches appropriées pour l'innovation technologique dans l'enseignement supérieur en Afrique. Les résultats principaux exposés dans cet article qui sont fondés sur trois études de cas suggérent que le e‐Learning doit être introduit dans un cadre stratégique fondé sur une vision clariment unifiée et une rationalisation centrale de l'éducation. De plus ces résultats mettent en évidence l'importance de l'utilisation combinée de plusieurs stratégies : stratégies autant en bas, de bas en haut, d'intérieur et d'extérieur pendant le processus de diffusion afin d'aboutir à la cohérence, la collégialité et la possession. Le processus de transformation technologique n'est pas un processus de translation sans à compris mais un de dislocation, de dilemmes, d'incertitudes et c'est un art de procéder au changement et à une transformation technologique soutenue puisque les hommes sont au c?ur de ce processus de transformation.

Technologische Innovations‐ und Umsetzungsstrategien für höhere Bildung in Afrika: Realität und Idealismus aufeinander abstimmen

Dieser Beitrag analysiert technologische Innovationstrategien und stellt Vorschläge für deren Einführung in höhereren Bildungsinstitutionen in Afrika zur Diskussion. Das Papier beschreibt Managementangelegenheiten bei der Umsetzung von eLearning unter besonderer Berücksichtigung seiner Anwendung in der höheren Bildung im Ausland und in Afrika und schlägt auch entsprechende Ansätze für die technologische Innovation im Bereich der höheren Bildung in Afrika vor. Das wesentliche Ergebmiss dieser Arbeit, die auf drei Fallstudien beruht, ist, dass eLearning innerhalb eines strategisch entwickelten Rahmens, basierend auf einer klaren und einheitlichen Sichtweise und einer zentralen bildungslogischen Grundlage eingeführt werden muß. Die Befunde heben weiter die Wichtigkeit hervor, eine Kombination von Strategien zu verwenden: Top‐Down, Bottom‐Up und Inside‐Out Strategien während des Ausbreitungsprozesses, um Kohärenz, Kollegialität und Eigentumsrechte zu erlangen. Der Prozeß technologischer Transformation ist nicht etwa eine sanfte Überleitung, sondern von Verfremdung, Dilemmata und Unsicherheit begleitet. Es ist eine Kunst, Änderung und nachhaltige technologische Transformation zu bewirken, da ja die Menschen das zentrale Element dieses Transformation-sprozesses sind.  相似文献

Despite a wealth of evidence showing the benefits of early childhood education and care (ECEC), in Turkey participation remains low and inequitably distributed, even though access to services is soaring. Drawing from previous findings, this paper will focus on different stakeholders’ views on a more integrated system of ECEC governance in Turkey. The research shows that Turkey, a country at the crossroads of forming the foundations of early childhood services, should consider the adverse effects of the current split system and focus on the integration of services to foster holistic development with the aim of offering quality and equity for all children.  相似文献

This paper deals with the implementation of integrated services providing early support for young children and their families. The integration of services is considered to have highly positive effects on the development of children and on the prevention of child neglect and maltreatment. Therefore, childcare centres have been developed into family centres offering different services in order to foster this integration. The implementation of integrated services requires adequate governance structures on different levels. The external level concerns the framework the state offers for the integration of services. On an intermediate level, the cooperation between different institutions on the local level is to be considered. The internal level is related to questions of management, organisational development and team building. Based on experiences from family centres in the Federal State of North Rhine-Westphalia (Germany), the paper focuses on these different aspects of the governance of integrated services.  相似文献

This paper draws upon empirical research to provide insights into current teacher learning practices under broader neoliberal conditions, and how the latter might be resisted. The paper contrasts neoliberal approaches to teachers’ learning with the Nordic tradition of educational action research and ‘Bildung’ as alternative resources to guide teachers’ and principals’ collective learning practices in schools, and draws upon empirical research to provide evidence of the benefits and challenges of doing so. The paper draws upon research into the learning practices of primary teachers in Australia, early childhood teachers in Sweden, and principals in Finland. The research reveals the influence of more Bildung-informed conceptions of educational action research, even as these are challenged by existing administrative cultures, and neoliberal pressures. The research presents ‘resources for hope’ to promote collective learning based on democratic values, not in an idealized or abstract manner, but in a way which is simultaneously cognizant of empirical realities.  相似文献

Generalizability theory was used to examine both the relative and absolute generalizability of the observed resistance, reactance, and phase angle measurements of total body bioelectrical impedance (Z) for men and women, using the Bioelectrical Impedance Analysis with modified electrode placement sites (Spectrum Lightweight Instrument; RJL Systems, Detroit, MI). Eighty men and 83 women from a military air force base volunteered as participants. RJL's rules for testing whole-body Z were followed with modification of the proximal electrode placement sites to the center of the antecubital space and popliteal fossa. The design was a 4-faceted crossed Person x Day x Occasion x Trial design treating all facets as random. Each participant was tested by 1 experienced tester on 2 days, 2 occasions, and 3 trials. Data were analyzed independently for each Z measurement anal each sex group. Overall, the modified electrode placement sites produced generalizability coefficients that were equal to or lower than the coefficients reported by Turner, Bouffard, and Lukaski (1996) using standard electrode placement sites. It is concluded that the standard method of measuring Z produces higher generalizability coefficients than the modified electrode placement method.  相似文献
