This article considers the extent and nature of student participation in a trade bargaining simulation from a community of practice perspective. This third‐year economics module included a blend of online communication (through email, online chats and online discussions) and face‐to‐face meetings, both in smaller bargaining groups and in whole class plenary meetings. Our method of analysis includes the use of Exchange Structure Analysis of text chats and face‐to‐face learning conversations, triangulated by observation, survey and interview data. The focus on community of practice enables us to offer a nuanced interpretation of differences in crude participation data derived from the online chats. Superficially, the data may suggest marginalisation of participants, but Wenger's (1988 ) notion of peripheral participation with a trajectory towards full participation reframes the disparities in terms of an active community of practice. Some members are fully engaged with the practices of trade bargaining from the early stages of the simulation, while others move towards full participation over the duration of the simulation. Our results suggest that the laboratory‐based online text chats did provide opportunities for student participation in the simulation, and that male and female students exhibited different patterns of participation in the chats.  相似文献

Higher education is under increasing pressure to re‐evaluate the place of practice in its programs and there are increasing demands for workplace‐based experiences to be built into undergraduate degrees. The paper reports on an extended responsive case study conducted in the School of Criminology and Criminal Justice at Griffith University between 1994 and 2004. The findings point towards a model that can be used to develop courses based around a set of key challenges that learners need to face, criteria for the university’s construction of worthwhile activities, and principles of procedure that are required in order to implement them. It is suggested that university curriculum planners should concentrate on a process model of teaching, learning and research rather than on the more traditional models that tend to treat knowledge as a commodity and emphasise its production, transmission and delivery.  相似文献

Factor mixture modeling (FMM) has been increasingly used to investigate unobserved population heterogeneity. This study examined the issue of covariate effects with FMM in the context of measurement invariance testing. Specifically, the impact of excluding and misspecifying covariate effects on measurement invariance testing and class enumeration was investigated via Monte Carlo simulations. Data were generated based on FMM models with (1) a zero covariate effect, (2) a covariate effect on the latent class variable, and (3) covariate effects on both the latent class variable and the factor. For each population model, different analysis models that excluded or misspecified covariate effects were fitted. Results highlighted the importance of including proper covariates in measurement invariance testing and evidenced the utility of a model comparison approach in searching for the correct specification of covariate effects and the level of measurement invariance. This approach was demonstrated using an empirical data set. Implications for methodological and applied research are discussed.  相似文献

Environmental education in schools is an important strategy in achieving environmental improvement. However, it needs to be based on children's understandings of environment rather than on assumptions of what children know and believe. This paper reports on a research project where school children's answers to a question 'I think the term/word environment means ' were analysed using the qualitative research method of phenomenography. Six distinct conceptions were isolated, ranging from the least sophisticated--environment as a place--to the most inclusive and expansive--environment and people in a relationship of mutual sustainability. An important qualitative difference was found between conceptions that treat the environment as an object and relational conceptions. The implications of these findings for environmental education are discussed.  相似文献

Revisiting emancipatory teacher research: a psychoanalytic perspective   总被引:1,自引:0,他引:1  
This paper addresses the issue of how human beings construct themselves as subjects and the parameters within which this is achieved. We question models in which idealism shapes the trajectory of identity formation and consider how identity might be seen alternatively as a somewhat awkward amalgam of identifications with diverse discursive domains. The particular focus is on teachers conducting ‘emancipatory’ practitioner research and on how the researcher understands his/her interface with the situation he/she is researching. We survey a range of theoretical models as offered by some leading writers, with particular reference to Jacques Lacan, and consider each in relation to how the teacher researcher might be understood. We provide as an example an account of one teacher researcher examining issues of ethnicity and gender in her secondary school French classes.  相似文献

The introduction of a large (950 students) new first year class was an opportunity to design and implement a programme on student‐centred learning, where lectures, tutorials, and other teaching activities emphasised student participation and were integrated to promote a good learning environment The programme is described here, together with the results of an evaluation by students at the end of the second trimester. Students responses indicate that a well structured course which integrates content and process results in high student participation and satisfaction. The findings also show that Socratic teaching methods are entirely feasible with very large classes, and result in high student participation.  相似文献

The early childhood educational field has garnered attention with initiatives to foster skill acquisition in young children prior to kindergarten entry. These initiatives, in conjunction with the rigorous demands of curricular reform and a burgeoning accountability movement, invoke questions regarding the adequacy of the instruments used to assess young children and the inherent difficulties in conducting such assessments. Because the effectiveness of education relies critically on the sound diagnoses of children's readiness for learning and the measurement of their subsequent progression throughout the schooling process, critical issues in early assessment must be addressed. An examination of past practices was synthesized with recent research to focus awareness on the insufficient content domain, restrictive context, adverse timing and questionable psychometric properties, specifically the inappropriate norms and low predictive validity, of many instruments. Both the implications of and compensatory strategies for each issue are considered. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 737–749, 2004.  相似文献
