Two studies were carried out during university workshops, and analyzed the effects of resource interdependence on student‐student interactions, and the impact of these interactions on performance. Students worked cooperatively, either on complementary information (positive resource interdependence) or on identical information (resource independence). In Study 1, analysis of videotaped interactions revealed that working on complementary information produced more positive interactions; however this was not sufficient to prevent students who had no direct access to the information from being disadvantaged, because of informational dependence. In Study 2, with simpler texts allowing better information transmission, performance was favored when students worked on complementary information. Moreover, working on identical information not only enhanced confrontations of point of views, it also elicited competence threat. Further analysis revealed that competence threat mediated resource interdependence effect on performance. Discussion provides insights into the conditions in which different cooperative methods can benefit learning. 相似文献
In the problem-based curriculum of the faculty of Law, students of the first year are guided by staff tutors or undergraduate student tutors in small tutorial groups. In this study, academic achievement of staff tutor-guided groups are compared with student tutor-guided groups. After an eight-week course students' level of academic achievement was tested by essay questions. Two methods of assessing students' performance are used: expert judgements and propositional analysis. Results of both methods used indicate that no differences in academic achievement occur. Students guided by student tutors perform as well as students guided by staff tutors. Several explanations are proposed to account for these results. 相似文献
This paper deals with the design process of a remote laboratory for labwork in chemistry. In particular, it focuses on the mutual dependency of theoretical conjectures about learning in the experimental sciences and technological opportunities in creating learning environments. The design process involves a detailed analysis of the expert task and knowledge, e.g., spectrophotometry as a method for the determination of the concentration of a compound in a solution. In so doing, modifications in transposing tasks and knowledge to the learning situation can be monitored. The remote laboratory is described, as well as the specific features that alter the degree of fidelity of the learning situation in comparison with the expert one. It is conjectured that these alterations might represent actual benefits for learning. 相似文献
Lifelong learning puts learner self-direction centre-stage. However, increased responsibility should not come at the price of over-burdening or abandonment of learners as they progress along their learning journey. This paper introduces an approach to wayfinding support for lifelong learners based on self-organisation theory. It describes an architecture which supports the recording, processing and presentation of collective learner behaviour designed to create a feedback loop informing learners of successful paths towards the attainment of learning goals. The approach is presented as an alternative to methods of achieving adaptation in hypermedia-based learning environments which involve learner modelling. The article concludes with a discussion of the questions being addressed in our ongoing research. 相似文献
There is emerging interest on the interactions between modelling and argumentation in specific contexts, such as genetics learning. It has been suggested that modelling might help students understand and argue on genetics. We propose modelling gene expression as a way to learn molecular genetics and diseases with a genetic component. The study is framed in Tiberghien’s (2000) two worlds of knowledge, the world of “theories & models” and the world of “objects & events”, adding a third component, the world of representations. We seek to examine how modelling and argumentation interact and connect the three worlds of knowledge while modelling gene expression. It is a case study of 10th graders learning about diseases with a genetic component. The research questions are as follows: (1) What argumentative and modelling operations do students enact in the process of modelling gene expression? Specifically, which operations allow connecting the three worlds of knowledge? (2) What are the interactions between modelling and argumentation in modelling gene expression? To what extent do these interactions help students connect the three worlds of knowledge and modelling gene expression? The argumentative operation of using evidence helps students to relate the three worlds of knowledge, enacted in all the connections. It seems to be a relationship among the number of interactions between modelling and argumentation, the connections between world of knowledge and students’ capacity to develop a more sophisticated representation. Despite this is a case study, this approach of analysis reveals potentialities for a deeper understanding of learning genetics though scientific practices. 相似文献
The present study was aimed at investigating whether and how image characteristics influence written naming performance in adults. In three different sessions, participants had to quickly write down the names of pictured objects on a graphic tablet. Across sessions, the picture format was different, but the to-be-named objects were the same: There were black-and-white pictures (Snodgrass & Vanderwart’s [SV] 1980 drawings), grayscale and colored pictures of the SV drawings as provided by Rossion and Pourtois (2004). Linear-mixed models (LMM) were used to analyze written latencies. The main findings were the following: (1) Colorized pictures yielded shorter written naming latencies than line drawings with the grayscale pictures being situated between the two; (2) Both within- and between-picture format LMM revealed reliable effects of name agreement, objective word frequency, frequency trajectory (the effect was marginal in the grayscale condition), and imageability on written latencies. The influence of image agreement was, however, less stable (reliable only in the colorized condition in the within-picture format LMM analysis; significant with both line drawings and their colorized version only in the between-picture format LMM analysis); (3) None of the interactions with picture format reached significance except the interaction of Image agreement with Picture format. In line with Bonin, Roux, Barry, & Canell (2012b), the findings support a limited-cascading account of written word production.
This report presents findings on an independent evaluation of an early intervention program for severely and profoundly deaf children. Located in Vancouver, British Columbia, this comprehensive program served families with children under age 3. The evaluation included comparison with a matched sample of deaf children without intervention. Included were a developmental assessment and videotape of linguistic and social interactions. Results indicated more developmentally mature communication and higher-quality interaction in families who had received intervention. 相似文献
The study analyzes the type and quantity of co-occurrence of social, cognitive, and teaching presence in a Community of Inquiry (CoI). Content analysis of the virtual educational communication shows units of analysis that must be assigned to more than one category. By crossing the categories of the CoI model, we observe that Social Presence is involved in all of the crossings and that graphic, linguistic, and paralinguistic elements change the meaning of the communication in the social, cognitive, and teaching interaction. We demonstrate the communicative richness of the educational encounters in which Social Presence interacts with the other elements and draw conclusions about the importance of support for communication in virtual communication. We stress the need to analyze co-occurrences to achieve a full analysis of computer-mediated communication. 相似文献
