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

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.     

近十年来教育研究的热点领域和前沿主题——基于八种教育学期刊2000-2009年刊载文献关键词共现知识图谱的计量分析

运用文献计量可视化软件CiteSpace绘制八种CSSCI来源教育学期刊2000-2009年刊载文献关键词的知识图谱,探测中国教育研究热点领域可以看到,在教育发展阶段为基础教育(义务教育)和高等教育;在学校、社会和家庭三个传统教育阵地为学校教育;在教育活动层面为教育改革、教育发展、教学研究、教学改革、课程改革、课堂教学、教学方法、教学模式;在教育理念层面为素质教育、创新教育和教育思想;在教育元研究层面为教育学学科建设和教育理论;教师教育和道德教育也是热点领域。在中国教育研究的前沿主题中,趋弱型前沿主要为创新教育、素质教育、教育观念、师范教育;渐增型前沿主要为教育质量、教育公平、教师发展、教师专业发展。

Using a concept mapping strategy to improve the motivation of EFL students in Google Hangouts Peer-Tutoring Sessions with native speakers

This study examines four elements of learner motivation, attention, relevance, confidence, and satisfaction, in an EFL speaking course that uses the computer mediated communication (CMC) tool Google Hangouts. The study found that a preparatory concept mapping task before the CMC sessions improved students’ perceived attention, relevance, confidence, and satisfaction. However, follow-up reflective worksheets had no effect on perceived attention, relevance, confidence, or satisfaction. Instructors should use concept mapping in a pre-task to support learners engaged in CMC-based speaking activities with native and non-native speakers. When the students used concept mapping to prepare for the CMC-based speaking activities, they exhibited higher confidence in their oral practice activities with a native speaker.
