The ‘Green Classroom’ in the Botanical Garden of Ulm is an experiential learning forum outside school. Its educational concept
is based on experimental learning and is geared towards expanding biological knowledge and developing positive attitudes towards
small animals such as invertebrates and insects. The attitudes of 68 school students towards small animals, before and after
they visited the ‘Green Classroom’, were assessed and the answers they gave in their questionnaires were compared with those
of 60 students froma control group that was not yet exposed to this learning environment. Although the students spent only
one morning in the ‘Green Classroom’, some of their attitudes towards small animals improved after their visit. These studies
underscore the necessity for direct observation and familiarization of the environment including small animals such as invertebrates
and insects for appreciating issues related to biodiversity and conservation. 相似文献

This article presents findings from a German–Swiss video-based classroom study. The research examines how three basic dimensions of instructional quality impact the development of students' understanding of the Pythagorean Theorem. The study sample comprised 19 German and 19 Swiss mathematics classes. A three-lesson introductory unit on the Pythagorean Theorem was videotaped in all classes. Multilevel analyses revealed both classroom management and cognitive activation to have positive effects on mathematics achievement. The results also provide empirical evidence that cognitive activation and a supportive climate moderate the relationship between mathematics-related interest and mathematics achievement. 相似文献

An implication of the current research on self-regulation is to implement the promotion of self-regulated learning in schools.
Teachers can promote self-regulated learning either directly by teaching learning strategies or indirectly by arranging a
learning environment that enables students to practise self-regulation. This study investigates teachers’ direct and indirect
promotion of self-regulated learning and its relation to the development of students’ performance. Twenty German mathematics
teachers with their overall 538 students (grade 9) were videotaped for a three-lesson unit on the Pythagorean Theorem. Students’
mathematics performance was tested several times before and after the observed lessons. A low-inferent coding system was applied
to assess the teachers’ implicit or explicit instruction of cognitive strategies (e.g., organisation), metacognitive strategies
(e.g., planning), and motivational strategies (e.g., resource management). High-inferent ratings were used to assess features
of the learning environment that foster self-regulation. Results reveal that a great amount of strategy teaching takes place
in an implicit way, whereas explicit strategy teaching and supportive learning environment are rare. The instruction of organisation
strategies and some features of the learning environment (constructivism, transfer) relate positively to students’ performance
development. In contrast to implicit strategy instruction, explicit strategy instruction was associated with a gain in performance.
These results reveal a discrepancy between the usefulness of explicit strategy instruction and its rare occurrence in classrooms. 相似文献

Adult Education has many values, including experiences and co-operation among people, and the fact that adult education is full of stories from adult educators, which can help to understand trends in the past and developments in the present. Established in 1991 as part of a more general regional cooperation among five Nordic and three Baltic countries (NB8), Nordic-Baltic cooperation in adult education has been mutually enriching and has resulted in the growth of a professional network. The cooperation has led participants through a time of new sources of values, knowledge and contacts, socialisation and transformation, inspiration and challenges, which has influenced their experiences and professional identities. This paper is based on the results of a study entitled “Nordic-Baltic cooperation in adult education: Experience and stories” and focuses on the experiences and professional identities of two generations of Estonian adult educators. The empirical data for the study were collected using narrative-biographical interviews. The paper discusses two research questions: (1) What is the perception and influence of experiences for adult educators? and (2) How have their experiences influenced the professional identity of adult educators? 相似文献

For more than a decade, competence development has been a key concept of modern management in both the private and the public
sector, but to some extent its meaning and practice have been different in the two sectors. In the public sector in particular,
competence development has been closely related to a number of other buzzwords characterizing dominant Neo-Liberal political
conceptions, such as Lifelong Learning, New Public Management, Market Orientation and Decentralization. From an idealistic
point of view, competence development is intended to promote professionalism, understood as knowledge creation, self-management
and the ethical commitment of civil servants. However, the development has increasingly involved elements of supervision,
declining flexibility and time consuming evaluation, which may have contributed to the de-qualification and de-motivation
of civil servants. It is therefore a basic question as to whether the learning activities normally labelled as competence
development are part of a developing or a dismantling process in relation to professionalism in the public sector. This paper
seeks to deal with this question in so far as it relates to the case of Denmark, which is usually regarded as a significant
example of the so-called Nordic Welfare State Model, implying the strong, democratic and service-minded role of the public
sector. 相似文献

Shareholder value, short-term strategies, quarterly financial reports, and performance-based remuneration are strong indicators of a financial market-oriented company. It is questionable whether innovativeness and sustainable innovation capabilities can be maintained in times of financialization focused on short-term efficiency instead of free space for creativity and learning. Using the example of established German industrial companies, I examined the extent to which financialization and financial market actors steer innovation strategies and practices. In-depth interviews with companies, cluster managers and banks and reviews of financing data do not reveal a direct influence of financial investors on innovation activities. On the contrary, companies’ managements still have the power to decide how much financial control and standardization they allow for their companies’ innovation practices. The pressure on these German companies to innovate comes from their strong market orientation rather than from financialization. 相似文献

The increasing commercialization of university discoveries has initiated a controversy on the impact for scientific research. It has been argued that an increasing orientation towards commercialization may have a negative impact on more fundamental research efforts in science. Several scholars have therefore analyzed the relationship between publication and patenting activity of university researchers, and most articles report positive correlations between patenting and publishing activities of scientists. However, previous studies do not account for heterogeneity of patenting activities. This paper explores the incidence of patenting and publishing of scientists distinguishing between corporate patents and patents assigned to non-profit organizations for a large sample of professors active in Germany. While patents assigned to non-profit organizations (incl. individual ownership of the professors themselves) complement publication quantity and quality, patents assigned to corporations are negatively related to quantity and quality of publication output. 相似文献

ABSTRACTThis article develops and troubles existing approaches to visual self-representation in social media, questioning the naturalized roles of faces and bodies in mediated self-representation. We argue that self-representation in digital communication should not be treated as synonymous with selfies, and that selfies themselves should not be reductively equated with performances of embodiment. We do this through discussing “not-selfies”: visual self-representation consisting of images that do not feature the likenesses of the people who share them, but instead show objects, animals, fictional characters, or other things, as in the practices of #EDC (“everyday carry”) and #GPOY (“gratuitous picture of yourself”) on platforms such as Tumblr, Facebook, Instagram, and reddit. We present an account of self-representation as an emergent, recognizable, intertextual genre, and show that #EDC and #GPOY practices are best conceptualized as instances of self-representation. 相似文献

This paper analyses whether strategic motives for patenting influence the characteristics of companies’ patent portfolios. We use the number of citations and oppositions to represent these characteristics. The analysis is based on survey data from German companies, which are combined with EPO data covering applications from 1991 to 2000. We find clear evidence that the companies’ patenting strategies are related to the characteristics of their patent portfolios. First, companies using patents in the traditional way to protect their technological knowledge base receive a higher number of forward citations for their patents. Second, the motive of offensive - but not of defensive - blocking is related to a higher incidence of oppositions, whereas companies using patents as bartering chips in collaborations receive fewer citations and fewer oppositions to their patents. 相似文献
