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

Abstract

This article considers human embodied relationships with the more-than-human world, in the Swedish forest context, and through a phenomenological approach. The research focuses on lived experiences of being-in-the-forest, starting in the author’s experiences, using walk-and-talk conversations as inquiry process with study participants. Analysis reveals that (a) childhood experiences seem to play a crucial role in adult experiences of forests; (b) place-identity and sense of belonging are significant elements in how the participants define themselves; (c) being-in-the-forest is connected to an active, exploring and moving body and that the connection with the more-than-human world of the case study forest is deeply anchored as part of the human body. This relationship appears to be shaped through a process of constructing and reconstructing memories, practice and selfhood, and can, it seems, last a lifetime. In the long term, such relationships could have a positive impact on human connections to the more-than-human world.  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

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

The work reported here involved a comparative study regarding the understanding that high school students (16–18 years) have of the concept of chemical elements and their periodic classification. More specifically, the level of knowledge on this topic was compared before and after the completion of baccalaureate studies in a sample of Spanish students. In order to achieve this goal, a questionnaire was developed that included 14 items in an open format, through which various aspects of the students’ understanding of the idea of chemical element and their periodic classification were assessed. In addition, the application of this knowledge to interpret and predict the behaviour and properties of elements and to carry out calculations on the atomic composition of the elements was evaluated. Aspects concerning the acquisition of scientific knowledge, the application of knowledge to different contexts and situations, and the use of scientific evidence to draw conclusions and knowledge about the nature and history of science were evaluated. The questionnaire was previously validated with a large group of students. The results of this study show that improvements occur primarily in addressing higher level cognitive questions (analysis, synthesis and evaluation) in comparison to the lower level tasks (capacity for retention, understanding or direct application of learning). In addition, students who start high school have a very limited understanding of the ideas behind the Periodic Table of the chemical elements and that their lack of understanding, to a large extent, remains upon completion of the baccalaureate. These results suggest that there are real difficulties in understanding this topic and show the limited influence of the studies completed in high school.  相似文献

The flipped classroom is becoming more popular as a means to support student learning in higher education by requiring students to prepare before lectures and actively engaging students during lectures. While some research has been conducted into student performance in the flipped classroom, students’ study behaviour throughout a flipped course has not been investigated. This study explored students’ study behaviour throughout a flipped and a regular course by means of bi-weekly diaries. Furthermore, student references to their learning regulation were explored in course evaluations. Results from the diaries showed that students’ study behaviour in the flipped course did not appear to be very different from that of students in a regular course. Furthermore, study behaviour did not appear strongly related to student performance in both the flipped and the regular course. Exploration of student references to their learning regulation in the course evaluations showed that some students experienced the flipped course design as intended to support their learning process. Other students, however, demonstrated resistance to changing their study behaviour even though changing study behaviour is expected in order to benefit from the flipped classroom. Further research on the relationship between students’ learning regulation and actual study behaviour and course results is necessary to understand when and why implementing the flipped classroom is successful. Recommendations that may help more effective flipped classroom implementation include considering the prior history between students and instructor(s), the broader curriculum context, and frequent expectation communication especially with large numbers of students and non-mandatory lecture attendance.  相似文献
