Learning from Comparing Multiple Examples: On the Dilemma of “Similar” or “Different”     

Jian-Peng Guo  Ming Fai Pang  Ling-Yan Yang  Yi Ding 《Educational Psychology Review》2012,24(2):251-269

Although researchers have demonstrated that studying multiple examples is more effective than studying one example to facilitate learning, the principles found in the literature for designing multiple examples remain ambiguous. This paper reviews variation theory research on example design which sheds light on unclear issues regarding the effects of example variability. First, the distinction of surface/structural should be replaced by critical/uncritical in example study. Aspects and features that are critical to students’ understanding should be identified and compared in example design. Second, variation as well as similarity among examples should be taken into consideration in example design. Certain patterns of variation and invariance should be adopted to systematically determine the variability of examples. Third, students with different levels of prior knowledge perceive different aspects of examples that are critical for their learning. Examples should be designed according to aspects that are critical to specific students.  相似文献   

Increasing Access for Economically Disadvantaged Students: The NSF/CSEM & S-STEM Programs at Louisiana State University

Increasing college degree attainment for students from disadvantaged backgrounds is a prominent component of numerous state and federal legislation focused on higher education. In 1999, the National Science Foundation (NSF) instituted the ??Computer Science, Engineering, and Mathematics Scholarships?? (CSEMS) program; this initiative was designed to provide greater access and support to academically talented students from economically disadvantaged backgrounds. Originally intended to provide financial support to lower income students, this NSF program also advocated that additional professional development and advising would be strategies to increase undergraduate persistence to graduation. This innovative program for economically disadvantaged students was extended in 2004 to include students from other disciplines including the physical and life sciences as well as the technology fields, and the new name of the program was Scholarships for Science, Technology, Engineering and Mathematics (S-STEM). The implementation of these two programs in Louisiana State University (LSU) has shown significant and measurable success since 2000, making LSU a Model University in providing support to economically disadvantaged students within the STEM disciplines. The achievement of these programs is evidenced by the graduation rates of its participants. This report provides details on the educational model employed through the CSEMS/S-STEM projects at LSU and provides a path to success for increasing student retention rates in STEM disciplines. While the LSU??s experience is presented as a case study, the potential relevance of this innovative mentoring program in conjunction with the financial support system is discussed in detail.  相似文献

1979-2010年我国图书馆史研究的定量分析     

庞弘燊 《国家图书馆学刊》2011,20(1):86-92

1979-2010年间关于图书馆史的研究可以按年代大致划分为三个时期。定量分析结果表明,三个时期内图书馆史研究的热点有细小变化,高校是主要的研究机构,高产作者发文量并不多,作者合著情况较少。共词聚类分析结果则表明,图书馆史研究主要集中在图书馆事业史、图书馆学史、图书馆发展史三类主题,高产作者的研究主题和研究兴趣较为广泛,并且有一定的重合度。表4。图4。参考文献10。  相似文献
