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

Children use the presence of familiar objects with known names to identify the correct referents of novel words. In natural environments, objects vary widely in salience. The presence of familiar objects may sometimes hinder rather than help word learning. To test this hypothesis, 3-year-olds (N = 36) were shown novel objects paired with familiar objects that varied in their visual salience. When the novel objects were labeled, children were slower and less accurate at fixating them in the presence of highly salient familiar objects than in the presence of less salient familiar objects. They were also less successful in retaining these word-referent pairings. While familiar objects may facilitate novel word learning in ambiguous situations, the properties of familiar objects matter. 相似文献

The recommended treatment for alcoholism in the past typically has been participation in Alcoholics Anonymous (AA). However, the use of AA on college campuses has not been proven effective. With a new generation comes the opportunity to rethink this approach to the problem of alcohol abuse on campuses and to incorporate new methods in counseling practice with young adults. 相似文献

In this paper, the focus is on one particular research project, conducted in the UK, which studied the role of parent groups and organizations in relation to the mainstream education system. The authors seek to analyze and evaluate access to the different "structures of feeling" inhabited by the various respondents involved in the project. Using the project as a lens, a critical case, the relationships between respondents and researchers are problematized, highlighting a number of issues with broad applicability. These include negotiating access, securing informed consent, the debates around symmetry and asymmetry between researcher and respondent, the processes of interviewing, data analysis and dissemination. The authors also comment on the formation and development of relationships with respondents, trying to tease out the differences and similarities of age, race, social class, language, and gender, and to suggest how these disjunctions and connections affected the process of datacollection and analysis. Finally, the article concludes with a brief consideration of the implications for future research design and conduct of the arguments put forward. 相似文献

This article explores heterogeneity as fundamental to learning. Inspired by Bakhtin's notion of heteroglossia, a design team consisting of an experienced classroom teacher and 2 researchers investigated how a class of 3rd and 4th graders came to understand disciplinary points of view on heat, heat transfer, and the particulate nature of matter. Through a series of planned and unplanned encounters, official versions of the Second Law of Thermodynamics and the particulate view of matter were juxtaposed with varied domains of experience of heat transfer and phase change in water. We analyze the children's discourse to examine how they populated these phenomena with meaning and what they learned in the process. We conclude by describing key principles and a conundrum that emerged from this research. 相似文献
