This article compares the learning approaches of students on an initial teacher education programme. Using a mixed method approach, the study examines differences between mature learners and direct entry students, across the domains of deep, strategic and surface learning approaches. Following the quantitative phase, group interviews were conducted to gain additional insights into the factors, which impacted learning approach. Significant differences were evident between both cohorts. The key categories that contributed to learning approach included; motivation to learn, collaborative and competitive learning, prior educational experiences and school placement. The findings provide insights into the diversity of student cohorts.  相似文献

通过对企业规模界定、企业进入联盟时间划分和企业进入联盟方式归纳,对企业进入联盟进行定性三维分类,构成的空间结构显示企业进入联盟存在8种类型,企业进入动机根据进入种类的不同存在差异。针对企业在进入联盟时存在信息获取不全面、企业进入和退出联盟机制不完善等阻碍,分别从联盟单位、政府和企业自身3个角度提出相应的完善对策。  相似文献

This study examined the effects of two types of Information communication technology and media (ICT/media) use on college access using ICT/media to obtain college information as a mediator paying focused attention to English language learners. The study analyzed the Educational Longitudinal Study (ELS) from the US Department of Education, employing a survival analysis with structural equation modeling components. The results demonstrated that the frequent use of a computer for independent learning had significantly positive direct, indirect, and total effects on college entry for both English language learners and native English-speaking students. However, the digital gameplay had significantly negative effects. The study discusses the implications of using ICT/media.  相似文献

According to an analysis of Korean student panel survey data, monthly differences in age had a significant influence on academic achievement until middle school (lower secondary education). However, this age effect did not persist when students graduated from high school (upper secondary education). Furthermore, some evidence is found that younger students, upon entering high school, were more likely to concentrate on academic studies, and less likely to experience minor distractions, thereby compensating for their poor academic achievement in middle school.  相似文献

This article considers the Australian entry score system, the Australian Tertiary Admissions Rank (ATAR), and its usage as a selection mechanism for undergraduate places in Australian higher education institutions and asks whether its role as the main selection criterion will continue with the introduction of demand driven funding in 2012. Admission strategies for undergraduate places in Australian universities have remained unchanged for many years. The author concludes that the current entry scheme, the ATAR, will continue as a dominant selection criterion particularly for courses where demand exceeds supply, but ATAR-based selection will be insufficient to meet the participation targets set by the federal government. There is now an opportunity for universities to differentiate themselves by their admission strategies and to improve participation of equity groups through the normalisation of alternative entry mechanisms.  相似文献

基于基波分析法( FHA)对LLC谐振变换器进行建模分析,并以此为依据提出一种简化的参数设计方法。该方法根据谐振电路的二端口模型得到归一化工作频率和电压增益的关系,按照规定输入输出的要求确定电压增益后得到谐振工作频率,进而可以得到谐振电路的特性阻抗和谐振腔元件参数。利用Saber软件仿真和硬件实验验证了该方法的有效性,表明所设计的变换器可实现开关管的零电压开通和整流二极管的零电流关断,能够降低开关损耗,提高装置效率。  相似文献
