Using digital technologies in mathematics teaching: developing an understanding of the landscape using three “grand challenge” themes     

Marie Joubert 《Educational Studies in Mathematics》2013,82(3):341-359

This paper develops an understanding of the issues, interests and concerns within the mathematics education community related to the use of computers and other digital technologies in the teaching and learning of mathematics. It begins by arguing for the importance of understanding this landscape of interests and concerns, and then turns to the theoretical and methodological choices made in this study, explaining how it has drawn on the approach developed by the STELLAR European Network of Excellence. By analysing the titles and abstracts of a conference chosen to represent the mathematics education community, it maps out the landscape framed by three “Grand Challenges”, finding that an understanding of orchestrating learning is at the heart of the interests of the community, and that the community is interested in exploring new and different contexts for the teaching and learning of mathematics. However, there is currently less interest in investigating and exploiting the increasing connectedness of learners within this community. Further, while the “Grand Challenges” framing is useful in mapping the landscape, it fails to take into account both the personal concerns of teachers and students, such as attitude and confidence, and issues related to doing research and understanding research concerns.  相似文献   

Preservice teachers’ work stress, self-efficacy, and occupational commitment in four countries

In this study, we examine the teaching-related stress, self-efficacy, and occupational commitment of preservice teachers from two culturally western and two culturally eastern countries. The sample included 1,187 participants from Canada (n?=?379), England (n?=?203), Hong Kong (n?=?211), and Thailand (n?=?394). Self-efficacy partially reduced (mediated) the effect of stress from student behavior and from workload on commitment in three of four contexts. Mediation tests with country as moderator revealed significant differences in the strength of the mediating effect across the four contexts. The results suggest that teachers’ self-efficacy changes the way in which work stress influences the commitment to continue teaching, although cultural milieu influences the nature of the relationship according to context.  相似文献   

Lyceum 1511 and Mountain Crest High School: An International Exchange Program Reveals Educational Contrasts     

Marina Parsegova  Galina Eltseva 《Clearing house (Menasha, Wis.)》2013,86(2):74-78

The arrival of underprepared freshmen to a high school presents a host of challenges for all stakeholders. West High School in Bakersfield, California, responded to a problem of academic failure of a significant number of freshmen by developing and implementing a Freshman Academy for underprepared students entering the 9th grade. During two years of this intervention, the school experienced improvement in the matriculation rate, an increase in literacy skills, and a reduction in student suspensions. The Freshman Academy identified students’ academic and nonacademic needs and provided a supportive learning environment to help address these needs in a way that led to successful promotion through high school. Two critical attributes of this approach are teacher efficacy and teacher collaboration.  相似文献   

Fellows' Perceptions of a Mandatory Reflective Electronic Portfolio in a Geriatric Medicine Fellowship Program     

Jorge G. Ruiz  Syeda S. Qadri  Marina Karides  Carmen Castillo  Marcos Milanez  Bernard A. Roos 《Educational gerontology》2013,39(7):634-652

Electronic portfolios (ePortfolios) can be useful for evaluating and documenting mastery of competencies. We investigated geriatric medicine fellows' perceptions of an ePortfolio. We conducted surveys and focus groups followed by quantitative and qualitative data analysis. Our study revealed that fellows considered the ePortfolio acceptable and accessible. Fellows reflected on aspects relevant to postgraduate training and future practice and documented adherence to competencies. However, fellows expressed resentment about the self-reflection component, which interfered with the overall acceptance of the ePortfolio. Although ePortfolios can be powerful and reflective tools for competency assessment, care must be taken in their implementation.  相似文献   

What Did It Take to Scale Up and Sustain Udaan,a School-Based Adolescent Education Program in Jharkhand,India?     

Venkatraman Chandra-Mouli  Marina Plesons  Alka Barua  Aparajita Gogoi  Manju Katoch  Mohammed Ziauddin 《American journal of sexuality education》2018,13(2):147-169

Since 2006, Udaan—a school-based adolescent education program in Jharkhand, India—was the only at-scale state-run program in the country. To determine factors that contributed to Udaan's scale-up and longevity, this study drew information from programmatic reports and interviews with the Centre for Catalyzing Change staff. Key factors for Udaan's success included an enabling policy environment, a willing government that supported and operationalized the program, a knowledgeable and committed NGO partner, sustained funding, and a commitment to constant improvement through evaluation. Udaan provides an example of a well-designed, implemented, and evaluated school-based adolescent health program that has been operating at scale over a sustained period. Other programs in India and elsewhere can benefit from learning from Udaan's experience.  相似文献   

Investigating the effects of foreign direct investment (FDI) on Croatian business     

Yonghee Cho  Tugrul U. Daim  Marina Dabic 《The Journal of High Technology Management Research》2017,28(2):208-220

Technological innovation plays a critical role in economic growth. The most advanced and new technologies are created by leading firms in developed countries. Global expansion, strategic outsourcing or off-shoring in leading companies has been growing to enrich their competitive advantage, while technology transfer of leading firms has been of more interest to emerging or developing countries for catching up and following the trajectory of economic growth proved in developed countries. Among various channels to acquire new technologies from leading firms, foreign direct investments (FDI) is one of the most effective channels through which technology can be transferred to subsidiaries in emerging markets. However, empirical study on the roles of technology transfer and the feedback loop from FDI remains still scarce. Thus, the purpose of this study is to analyze the effects of FDI on businesses in partial or complete foreign ownership, with a special emphasis on technology transfer, and to assess the impact of foreign companies on domestic firm performance through technology transfer from foreign companies. This paper aims at investigating the investment climate for foreign investments and intensifying technology transfers and innovations in the Croatian economy. 145 firms responded to the survey we conducted for foreign investment enterprises in Croatia. Structural equation model is employed to examine the hypotheses with respect to effects of FDI on innovation activities of domestic Croatian firms. This study identified critical factors affecting technology innovation to Croatian firms. The results provide empirical evidence that the innovation activities in subsidiaries have a positive influence toward technology transfer from multinational corporations.  相似文献   

Antecedents of cooperative commercialisation strategies of nanotechnology firms     

Marina Fiedler  Isabell M. Welpe 《Research Policy》2010,39(3):400-410

We examine the antecedents for cooperative behaviour in the commercialisation of nanotechnology for both small/medium and large firms. For small and medium firms (SMEs) our results confirm the influence of complementary assets and transaction costs, but surprisingly do not support any influence of intellectual property rights protection on cooperative behaviour. For large firms the results show a negative relationship for both intellectual property rights protection and ownership of complementary resources with cooperative behaviour. Overall, collaboration-based commercialisation in nanotechnology for both small/medium as well as large firms seems to follow antecedents previously identified in earlier studies. In addition, we find that in the current stage of the nanotechnology commercialisation environment, intellectual property rights protection for small/medium-sized enterprises is associated with the acquisition of other firms.  相似文献
