An important recent development in the achievement goal literature is to define achievement goals strictly as aims. In this overview, we argue that this restrictive definition of achievement goals paves the way for a systematic consideration of the autonomous and controlled reasons underlying individuals’ achievement goals, a distinction central to self-determination theory. To stimulate work in this area, we formulated five propositions, arguing that consideration of the “why” (i.e., type of reasons) in addition to the “what” (i.e., type of aims) of achievement goals (a) provides an account for the regulatory basis of achievement goals, (b) opens the door for other motivation theories to be linked to the achievement goal literature, (c) matters in terms of predicting outcomes, (d) allows for a richer account of contextual forces influencing motivation, and (e) sets the stage for an enriched hierarchical model of achievement motivation. In closing, we discuss various future research directions.  相似文献

This study characterises the links between research and practice across 12 projects concerned with the collaborative design of lesson plans by teacher communities (TCs). Analyses focused on sources of knowledge used to inform lesson design, participants’ roles and knowledge generated by the teacher community. Three patterns emerged pertaining to the sources of knowledge informing lesson plans: design guided by formal and practical knowledge, by classroom-data and practical knowledge or by a combination of all three. Findings further suggest that the emphasis given to the use of formal knowledge over classroom-data or vice versa restrains the full accomplishment of research and practice links. Across the projects studied, university researchers contributed to linking research and practice by directly or indirectly supporting community activities. Surprisingly, the role of teachers in the generation and dissemination of formal knowledge was limited. Further research should explore the effects of collaboration within TCs on researchers and policy-makers.  相似文献

There does not appear to be consensus on how to optimally match students during the peer feedback process: with same-ability peers (homogeneously) or different-ability peers (heterogeneously). In fact, there appears to be no empirical evidence that either homogeneous or heterogeneous student matching has any direct effect on writing performance. The current study addressed this issue in the context of an academic writing task. Adopting a quasi-experimental design, 94 undergraduate students were matched in 47 homogeneous or heterogeneous reciprocal dyads, and provided anonymous, formative peer feedback on each other’s draft essays. The relations between students’ individual ability or dyad composition, feedback quality and writing performance were investigated. Neither individual ability nor dyad composition directly related to writing performance. Also, feedback quality did not depend on students’ individual ability or dyad composition, although trends in the data suggest that high-ability reviewers provided more content-related feedback. Finally, peer feedback quality was not related to writing performance, and authors of varying ability levels benefited to a similar extent from peer feedback on different aspects of the text. The results are discussed in relation to their implications for the instructional design of academic writing assignments that incorporate peer feedback.  相似文献

Within the higher education context, peer feedback is frequently applied as an instructional method. Research on the learning mechanisms involved in the peer feedback process has covered aspects of both providing and receiving feedback. However, a direct comparison of the impact that providing and receiving peer feedback has on students’ writing performance is still lacking. The current study compared the writing performance of undergraduate students (N = 83) who either provided or received anonymous written peer feedback in the context of an authentic academic writing task. In addition, we investigated whether students’ peer feedback perceptions were related to the nature of the peer feedback they received and to writing performance. Results showed that both providing and receiving feedback led to similar improvements of writing performance. The presence of explanatory comments positively related both to how adequate students perceived the peer feedback to be, as well as to students’ willingness to improve based upon it. However, no direct relation was found between these peer feedback perceptions and students’ writing performance increase.  相似文献

Informal learning in blended and online settings plays an increasingly important role in the continuous professional development of individuals. Yet, how do individuals engage into these types of activities? We argue that social capital theory can provide valuable insights into how people behave and decide to take part in (in)formal learning. Using social network analysis, we provide empirical evidence on an informal learning activity, where participants collaboratively created knowledge on wiki sites on a predefined set of topics. Our results show that there are three types of active participants in these types of informal learning activities, namely leaders, collaborators and lone editors. These findings provide valuable insights for other, similar activities that aim at enhancing the professional development of individuals.  相似文献

In this study, dynamic testing principles were applied to examine progression of analogy problem solving, the roles that cognitive flexibility and metacognition play in children's progression as well as training benefits, and instructional needs of 7‐ to 8‐year‐old gifted and average‐ability children. Utilizing a pretest training posttest control group design, participants were split in four subgroups: gifted dynamic testing (n = 22), gifted unguided practice (n = 23), average‐ability dynamic testing (n = 31), and average‐ability unguided practice (n = 37). Results revealed that dynamic testing led to more advanced progression than unguided practice, and that gifted and average‐ability children showed equivalent progression lines and instructional needs. For children in both ability categories, cognitive flexibility was not found to be related to progression in analogy problem solving or training benefits. In addition, metacognition was revealed to be associated with training benefits. Implications for educational practice were provided in the discussion.  相似文献

Considerable differences exist in the size and direction of the relationship between television viewing and fear of crime found by previous studies. This article argues that different types of fear exist and that fear should not be confused with perception of risk. A distinction was introduced between dispositional fear of crime and situational fear of crime. The relationship between television viewing and the two types of fear was examined and a distinction was made between direct, indirect, and mediated experience with crime. Hawkins and Pingree (1990 Hawkins , R. P. , & Pingree , S. ( 1990 ). Divergent psychological processes in constructing social reality from mass media content . In N. Signorielli & M. Morgan (Eds.), Cultivation analysis: New directions in media effects research (pp. 3550 ). Newbury Park , CA : Sage . [Google Scholar]) hypothesized that direct experience would interact negatively with television viewing, whereas cultivation's resonance hypothesis assumed a positive interaction. Face-to-face interviews were conducted with 1,394 adults in Flanders, Belgium. Television viewing was positively related to dispositional fear of crime, whereas direct experience with crime was not. Direct experience predicted situational fear of crime, whereas television did not. There were no interaction effects. This study suggests that the relationship between television viewing and fear of crime depends upon the operationalization of the concept of fear of crime. More research is needed to establish which types of fear exist and how they are related to television viewing and direct experience with crime.  相似文献

A library service model that provides reference and instructional services by summoning reference librarians from a single service point is described. The system utilizes Libraryh3lp, an open-source, multioperator instant messaging system. The selection and refinement of this solution and technical challenges encountered are explored, as is the design of public services around this technology, usage of the system, and best practices. This service model, while a major cultural and procedural change at first, is now a routine aspect of customer service for this library.  相似文献

The history of science shows a shift from single-investigator ‘little science’ to increasingly large, expensive, multinational, interdisciplinary and interdependent ‘big science’. In physics and allied fields this shift has been well documented, but the rise of collaboration in the life sciences and its effect on scientific work and knowledge has received little attention. Research in biology exhibits different historical trajectories and organisation of collaboration in field and laboratory – differences still visible in contemporary collaborations such as the Census of Marine Life and the Human Genome Project. We employ these case studies as strategic exemplars, supplemented with existing research on collaboration in biology, to expose the different motives, organisational forms and social dynamics underpinning contemporary large-scale collaborations in biology and their relations to historical patterns of collaboration in the life sciences. We find the interaction between research subject, research approach as well as research organisation influencing collaboration patterns and the work of scientists.  相似文献
