The purpose of this paper is to investigate whether the experiential learning of electronics subject matter is effective in the middle school open learning of robotics. Electronics is often ignored in robotics courses. Since robotics courses are typically comprised of computer-related subjects, and mechanical and electrical engineering, these three areas should be emphasized equally. Many studies reveal impressive learning of computer science and mechanical engineering, but clear evidence of the effectiveness of electronics learning in the higher order thinking skills of middle school students is still lacking. We designed three different robotics courses with electronics subject matter introduced through experiential learning. A parallel group design was used, where three different open learning courses were implemented for middle school students. Based on results of the first and second implementations, we improved students’ learning of relevant content for each successive step of the experiment. In total, 381 middle school students participated in all experiments and were surveyed using pre- and post-tests. The collected data were analyzed using a quantitative research methodology. The findings revealed that the teaching approach was effective. During the learning process, student interest in robotics increased, and overall achievement improved with a medium effect size (η2 = 0.13). The best results for the learning of electronics subject matter were found in the learning process (η2 = 0.44), where experimental sharing of electronics parts was the most evident approach used by the students. Examination of learning material structure in light of the shared electronics subject matter is analyzed and discussed and possible directions for future research are presented.  相似文献

This article determines whether transaction cost theory can be used as a framework for analysing industrial district relationships, using the Gnosjö/Anderstorp industrial district in Sweden as a case example. Interviews with six firm owner/managers, representatives from the trade union and the local industrial development centre were conducted. Data was analysed using pattern matching in accordance to the theoretical framework. The findings indicate that interfirm relationships in the industrial district are motivated by the desire to reduce transaction costs. The article offers an alternative perspective in analysing industrial districts as current studies use network theory in explaining the industrial district phenomena.  相似文献

This study uses a structural equation modeling technique to predict the internationalization of small and medium‐sized enterprises (SMEs) from the entrepreneur's human capital (dimensions: international business skills, international orientation, environmental perception, and management know‐how). While international orientation and environmental risk perception predicted internationalization, international business skills and management know‐how did not. The implications of these findings for research and practice are discussed. Copyright © 2007 ASAC. Published by John Wiley & Sons, Ltd.  相似文献

This article questions whether the unemployment invariance hypothesis of Layard et al. (2005), which states that movements in labour force do not significantly affect unemployment rates, holds true for Romania. Using quarterly labour force data for the 1996–2012 period, we explore the time-series properties of the two variables. We find that unemployment rates and participation rates have unit roots, and that they are not cointegrated, meaning that no significant long-term relationship exists between them. The analysis carried out on the first differences of unemployment rates and participation rates shows discouraged and added worker effects for Romania’s female labour force. This conclusion diverges from findings that point out to a stable, long-term relationship between unemployment and participation in several developed countries (Japan, Sweden, USA) and shows that Romanian labour market is highly adaptive, where changes in labour force participation do not lead to increases in unemployment. This finding can help model the influence of adverse developments such as ageing and emigration, and show their true impact beyond demographic doom scenarios. It also points out the role played by labour demand in shaping the evolution of the Romanian labour market.  相似文献
