Monitoring collaborative activities in computer supported collaborative learning     

Donatella Persico  Luigi Sarti 《Distance Education》2010,31(1):5-22

Monitoring the learning process in computer supported collaborative learning (CSCL) environments is a key element for supporting the efficacy of tutor actions. This article proposes an approach for analysing learning processes in a CSCL environment to support tutors in their monitoring tasks. The approach entails tracking the interactions within the communication platform to identify cues of the participative, social, cognitive, and teaching dimensions of the learning process. Both quantitative and qualitative indicators are employed to achieve a complete and thorough picture of the learning dynamics. A set of methodological and technological tools based on this approach has been tried out in the context of the online component of a blended course in educational technology addressing trainee teachers. The results of the study support the applicability of the proposed approach to content domains where discussion and reflective practice are the most effective learning strategy.  相似文献

Entrepreneurship: Exploring the knowledge base   总被引：1，自引：0，他引：1  

Hans Landström  Gouya Harirchi 《Research Policy》2012,41(7):1154-1181

Entrepreneurship research has a long tradition and since the 1980s the field has grown significantly. In this study we identify the ‘knowledge producers’ who have shaped the field over time and their core entrepreneurship research works. A unique database consisting of all references in twelve entrepreneurship ‘handbooks’ (or state-of-the-art books) has been developed. The chapters in these handbooks were written by experts within the field, and it can be assumed that the most frequently cited references represent ‘core knowledge’ with relevance to entrepreneurship research.From our analysis, it appears that entrepreneurship is a rather changeable field of research, closely linked to disciplines such as ‘management studies’ and ‘economics’. Over time, the field has become more formalized with its own core knowledge, research specialities and an increasing number of ‘insider works’. However, it is still based on some fairly old theoretical frameworks imported from mainstream disciplines, although during the last decade we have seen the emergence of a number of new field-specific concepts and theories. We argue that to successfully develop entrepreneurship research in the future, we need to relate new research opportunities to earlier knowledge within the field, which calls for a stronger ‘knowledge-based’ focus. We would also like to see greater integration between the fields of entrepreneurship and innovation studies in the future.  相似文献

运动员高原训练返回平原训练血象指标的变化观察     

刘艳 《体育科技》2012,33(3):61-64

探讨运动员高原训练之后返回平原训练的血象指标变化规律。方法:取10名广西自由式摔跤男子运动员高原训练之后返回平原训练的不同时段(第3、14、28、35天),分别测试红细胞计数(RBC)、血红蛋白(HB)、红细胞压积(HCT)、白细胞(WBC)及分类、血小板(PLT)等18项血象指标。结果:RBC、HB、HCT在不同时段出现不同的变化,其中第3天至14天是逐渐下降的过程,14天形成一个低谷,28天回升到高峰,第35天又呈下降趋势,差异有统计学意义(P<0.01)。WBC及分类、血小板等指标也有一定的规律性变化,但无统计学意义。结论:运动员高原训练之后返回平原训练的不同时间血象指标的变化有一定规律性,对评定高原训练的效果及运动员机能状态和体能的恢复情况的准确判断有着重要意义。  相似文献
