The differential effects of prior knowledge on learning: A study of two consecutive courses in earth sciences     

Ron Hoz  Dan Bowman  Ely Kozminsky 《Instructional Science》2001,29(3):187-211

We studied the occurrence and nature of learningin a university first year Introduction toGeomorphology course, and its relations with priorknowledge taught in a prerequisite course, and withthe prior knowledge in the to be learned subjects. Tendimensions of knowledge were tapped before and afterthe course by conventional and cognitive structuremeasures that were derived by the concept mappingmethodology. The fine-grain analysis of learningoutcomes yielded the following results: (a) studentsacquired only a small portion of the content in thecourse Introduction to Geomorphology, (b) the priorgeological and geomorphological knowledge did notaffect the learning of the new geomorphologicalcontents, (c) the minor effects appeared within ratherthan across knowledge dimensions, and they affectedmainly the learning of smaller knowledge units, and(d) concept definition cannot be considereda valid probe of knowledge. The differential effects of prior knowledge question thecentral, global and undifferentiated role that schematheories ascribe to prior knowledge in futurelearning. They call for greater reference to theexposed dimensions of knowledge by suggestingadditional factors to be considered in the sequencingof courses, as well as to the acquisition of complexknowledge with partial meaning of the basic knowledgeunits, and the use of new cognitive structure probesof knowledge.  相似文献

关系网络与创业机会识别:创业学习的多重中介效应          下载免费PDF全文

陈文沛 《科学学研究》2016,34(9):1391-1396

基于178家企业的样本数据,研究关系网络影响创业机会识别的内在机制。结构方程建模分析结果表明:关系网络不仅可以直接预测创业机会识别,还可以通过认知和经验学习以及实践学习间接预测创业机会识别。此外认知和经验学习对创业机会识别的预测作用相同,认知学习相比于经验学习对实践学习的预测作用则更强。  相似文献   

创业直觉研究述评及展望     

张慧玉  李华晶  胡望斌 《科学学与科学技术管理》2016,(8):20-33

直觉在创业者决策实践中至关重要,但理论界对此却关注不足,国内相关研究尤为匮乏。从直觉与创业关系出发,提炼创业直觉概念内涵,剖析影响创业直觉的内外部因素及其作用过程,挖掘创业直觉对创业者、创业行为和新企业的作用机制,据此构建了创业直觉研究的理论框架。框架关注创业直觉的驱动机制、本质特征和效应机制三个环节,兼顾中间机制和边界条件,明晰了相关理论基础、研究视角、分析方法和研究内容,对开展实证研究和情境化检验具有参考意义。  相似文献   

Component skills of text comprehension in less competent Chinese comprehenders   总被引：1，自引：0，他引：1  

Leong CK  Hau KT  Tse SK  Loh KY 《Annals of dyslexia》2007,57(1):75-97

The present study examined the role of verbal working memory (memory span and tongue-twister), two-character Chinese pseudoword reading (two tasks), rapid automatized naming (RAN) (letters and numbers), and phonological segmentation (deletion of rimes and onsets) in inferential text comprehension in Chinese in 31 less competent comprehenders compared with 37 reading comprehension control students and 23 chronological age controls. It was hypothesized that the target students would perform poorly on these cognitive and linguistic tasks as compared with their controls. Furthermore, verbal working memory and pseudoword reading would explain a considerable amount of individual variation in Chinese text comprehension. RAN would have a nonsignificant role in text comprehension. Structural equation analyses and hierarchical multiple regression analyses generally upheld these hypotheses. Our findings support current literature of the role of verbal working memory in reading comprehension found in English. The results, however, suggest differential role of the constructs and the tasks in reading comprehension and provide some answers for comprehension impairment in Chinese students.  相似文献   

现代日语量词“本”的认知考察     

吕春燕 《黑龙江教育学院学报》2007,26(12):152-156

现代日语量词"本"的原型用法是表示细长物体的量,其扩张用法是表示运动时有轨迹的物体的量,边缘用法则是表示没有具体形状、但是内容上连贯,或时间上先后发生的、属于一个完整事件——比如人类的语言活动"记事"、"连载"、"讲演"等较新事物的量。另外日语中量词的使用,因不同事物,以及同一事物不同状态而不同。  相似文献   

“V＋个＋VP”构式研究     

邓媛媛  廖巧云 《四川师范学院学报》2011,(2):67-72

本文拟从认知构式语法角度探讨＂V＋个＋VP＂这个汉语中常见结构在形式、功能上的独特性。我们认为＂V＋个＋VP＂是不可替代有着独特构式义的构式,具有以下两个主要语用特征：表达＂随意,彻底＂等特殊情感;＂个＂突出焦点的作用。在现实需求的基础上,由同一层面的五个图式构式经过传承压制而成,而具体构式又是图式构式的例示,双方互为理据性。形成了由处在两端的原型子构式（动宾构式和动补构式）及介于两者之间的连续体构成。  相似文献   

二语语法显性与隐性学习的认知研究     

岑海兵 《安庆师范学院学报(社会科学版)》2011,30(4):32-36

二语习得研究中对显性与隐性学习的关系存在着不同的认识,但从基于认知心理学对二语语法学习所作的研究来看,显性和隐性学习是两个相互独立又相互依存的学习机制。因此,在二语语法教学中,应把显性和隐性学习有机结合起来,采用动态平衡的语法教学模式,使两种学习机制的效用相互转化,相互作用,共同提高语法教学的效率。  相似文献   

亲师互动现状调查分析     

郝翌钧  郝若平 《教育理论与实践》2011,(30)

通过对家长和教师亲师互动的现状进行调查,结果表明:(1)家长亲师互动整体水平最好的是策略互动,其次为认知互动,最后为情感互动。而教师亲师互动中最好的是情感互动,其次为认知互动,最后为策略互动。(2)家长亲师互动在性别上只有认知维度存在显著差异,女性更好;在文化程度上除策略维度没有差异外,认知维度和情感维度均存在显著差异。  相似文献
