学科知识图谱研究:由知识学习走向思维发展     

范佳荣  钟绍春 《电化教育研究》2022,43(1):32-38

技术的发展加速教育进入智慧学习时代,新时代对人的培养提出了新的要求,对于如何以知识为基础或载体发展、转化、升华成学科思维成为学界关注的焦点。文章通过文献分析,提出了以问题为线索的学科知识图谱,并从心理学和哲学视角找寻理论依据,完成对思维内涵及其形成过程的把握;从知识抽取技术、语义链接技术和可视化技术三方面论证学科知识图谱构建的技术可行性。基于此设计了以问题体系为核心,向下回溯知识体系,向上抽象能力体系的学科知识图谱结构模型,提出了基于学科知识图谱的思维发展机制,在揭示知识建构与思维发展关系的基础上,从问题解决触及思维本质,以期为人的培养从知识习得走向思维发展的教育实践提供指导。  相似文献   

高考英语书面表达评分标准的问题与建议     

李迅辉 《考试研究》2014,(2):64-72

随着新课程改革的不断深入,教学理念逐步更新,学生的英语水平也在逐渐提高,但沿用多年的高考英语书面表达的评分标准并没有与时俱进,已经不能完全适应英语教学改革的要求。笔者认为,与《课程标准》相对照,它存在对学生的书面表达能力要求偏低的问题;与托福等考试的写作评分标准相比较,其整体评分方式不确定度相对较大,分项式描述不尽合理。针对上述问题,本文提出了"改良的整体评分法"的建议。  相似文献   

活性半月板移植     

张弛  陈国庆  王晔平  胡声宇 《武汉体育学院学报》2003,37(1):53-55

本研究采用新鲜半月板，保持其活性进行移植，用于修复损伤退变的半月板。有12例患在术后2年仍可见活性半月板组织。术后用HSS评分来评价，第1年得分高，超过175的占72％，4年后67％的患评分仍然高于175，22％的人评分在100－175之间，11％的人评分低于100。短期的术后随访不足以得出正确结论，但目前尚未发现负面影响，对其能否取得功能上的远期疗效还需进一步探索。  相似文献

Firms’ genetic characteristics and competence-enlarging strategies: A comparison between academic and non-academic high-tech start-ups   总被引：1，自引：0，他引：1  

Massimo G. Colombo Evila Piva 《Research Policy》2012,41(1):79-92

This paper argues that academic high-tech start-ups exhibit peculiar “genetic characteristics” that leave an enduring imprint on firm development. We formulate a series of hypotheses on the effects of such genetic characteristics on the post-entry strategies that academic high-tech start-ups adopt to enlarge their initial competence endowments. In the empirical section, we use matched-pair statistical techniques and run several regressions to test the theoretical hypotheses. Our findings contribute to the literature on the antecedents of the strategies adopted by academic high-tech start-ups. They also allow us to derive implications for academic entrepreneurs, university managers and policy makers.  相似文献

Cultivating Student Global Competence: A Pilot Experimental Study     

Yulong Li 《Decision Sciences Journal of Innovative Education》2013,11(1):125-143

Although student global competence has been recognized as an important learning outcome by more and more colleges and universities, campus internationalization efforts remain fragmented and largely ineffective. We proposed a pedagogical intervention that provided students from China and the U.S. with opportunities to establish virtual contact and to work collaboratively on international business related research papers. Then, we operationalized global competence as a three‐dimensional concept and designed an instrument to measure student global competence. The results provided some initial evidence on American students’ significantly lower performance in global knowledge and attitude, and confirmed the proposed pedagogical intervention as an easy‐to‐use and effective supplement to develop student global competence.  相似文献   

CAMPUS EARLY CHILDHOOD LABORATORY SCHOOLS: PARTNERS IN TEACHER EDUCATION PROGRAMS     

Jaesook L. Gilbert 《Journal of Early Childhood Teacher Education》2013,34(1):67-74

Abstract

Making Theory and Development of Early Childhood Education come alive for elementary master's degree students in two learning sites offers opportunities and challenges. In constructing the class, a primary goal was to expose the students to the context under which early childhood educators developed programs and theories. Also, students were challenged to uncover the relationship that the education of young children had with social change and emerging human rights. Utilizing distance learning, contemporary books such as Who Moved My Cheese (Johnson, 1998) and a field trip to the National Civil Rights Museum and the Rock'n Soul Museum, students developed a sense of the place early childhood education had and continues to have in social change and the advancement of civil rights in this country.  相似文献
