Vicarious learning from dialogue and discourse

This study examined learning in the domain of sentence parsing and syntax treediagram construction. The aim of the study was to assess whether subjects could learn vicariously from recordings of interactions between a previous student and a tutor.Four intervention conditions and a control condition were compared. Subjects in a dialogue group (DL) read printed tutorial notes and subsequently vicariously viewed dynamic (animated) recordings of tree diagrams being constructed by a previous student in the presence of a tutor.The discourse (DI) condition was similar except that subjects viewed recordings of tree diagrams being constructed by a tutor who concurrently verbalised instructional discourse.In a third condition (DO), subjects viewed tree-diagram construction animation clips which were not annotated with either dialogue or discourse. In a linear text (LT) condition, subjects were given only printed tutorial notes. A control (CO) condition involved pre and post testing without any intervention.Results indicated that the dialogue condition was as effective as the discourse condition. This provides support for contention that re-usable dialogue is a useful resource for the vicarious learner. Another finding was that un-annotated animated diagrams were surprisingly effective. Several reasons for their effectiveness are suggested from the literature on instructional animations.     

示意图提示条件下小学生数学问题解决的研究

学生对示意图提示条件普遍持肯定态度;学校教学水平影响学生非视觉化题目上的态度反应,而不影响视觉化题目上的态度反应.从整体上看,示意图提示条件能显著地促进学生的解题,但是这种促进作用受题目视觉化程度、学校教学水平的制约.在一定范围里,随着非视觉化题目难度增加示意图提示条件的作用在增强.

Representational Issues in Students Learning About Evaporation

This study draws on recent research on the central role of representation in learning. While there has been considerable research on students’ understanding of evaporation, the representational issues entailed in this understanding have not been investigated in depth. The study explored students’ engagement with evaporation phenomena through various representational modes. The study indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science through an investigation of students’ responses to a structured classroom sequence and subsequent interviews over a year. A case study of one child’s learning demonstrates the way conceptual advances are integrally connected with the development of representational modes. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both (a) richer conceptual understanding by students, and (b) enhanced teacher insights into students’ thinking.

从视觉文化角度对电影的解读

明时代是以字的出现作为标志的。字时代把人类对于事物的直接观察的重要性．让渡给了对于字意义的体会。这种强调对意义把握的明，成为人类进步的骄傲，也成为束缚人自由思考、自由感受的藩篱。以电影为发端的视觉化的出现，首次逆转了明的演进趋向。这种趋向在电视和电脑网络的信息传达中得到进一步强化和深化。
