Learning communities and fair trade in doctorates and development: report of a collaborative project
Janinka Greenwood Safayet Alam Abu Nayeem Mohammad Salahuddin Mollah Mohammed Haroon-Ar Rasheed 《Globalisation, Societies & Education》2016,14(1):49-67
This article reports the second stage of a study examining an academic partnership in which Bangladeshi doctoral students in a western university focus their research in the grounded context of Bangladesh and investigate the processes for change. After briefly outlining the previous published stage which examined the academic trade in higher education with developing countries, the article builds on the concept of fair academic trade to critically reflect on the development of a doctoral learning community, a publication project and three specific doctoral studies. The methodological approach is one of participatory action research, with focus on critical reflection on practice. 相似文献

When deciding whether to explore, agents must consider both their need for information and its cost. Do children recognize that exploration reflects a trade-off between action costs and expected information gain, inferring epistemic states accordingly? In two experiments, 4- and 5-year-olds (N = 144; of diverse race and ethnicity) judge that an agent who refuses to obtain low-cost information must have already known it, and an agent who incurs a greater cost to gain information must have a greater epistemic desire. Two control studies suggest that these findings cannot be explained by low-level associations between competence and knowledge. Our results suggest that preschoolers’ theory of mind includes expectations about how costs interact with epistemic desires and states to produce exploratory action. 相似文献

With the implementation of P.L. 99-457, early intervention programs are becoming more widespread; they are also being pressed to become more accountable. Persons evaluating early intervention programs have typically adopted outcome-oriented approaches focusing exclusively on measuring the dependent program variable (i.e., changes in student measures). This article highlights some of the problems inherent in these traditional approaches to program evaluation. A number of recommendations are offered for assessing the independent variable with the same methodological rigor that is typically reserved for measuring student outcomes in program evaluation studies. The implications of this shift in methodological approach are discussed in terms of improving the ability to replicate successful programs, design new ones with increased efficiency, and provide long-lasting support for early intervention. 相似文献

Case-based reasoning and instructional design: Using stories to support problem solving 总被引:2,自引:0,他引:2
David H. Jonassen Julian Hernandez-Serrano 《Educational technology research and development : ETR & D》2002,50(2):65-77
With an increased emphasis on problem solving and problem-based learning in the instructional design field, new methods for
task analysis and models for designing instruction are needed. An important methodology for both entails the elicitation,
analysis, and inclusion of stories as a primary form of instructional support while learning to solve problems. Stories are
the most natural and powerful formalism for storing and describing experiential knowledge that is essential to problem solving.
The rationale and means for analyzing, organizing, and presenting stories to support problem solving are defined by case-based
reasoning. Problems are solved by retrieving similar past experiences in the form of stories and applying the lessons learned
from those stories to the new problems. In this paper, after justifying the use of stories as instructional supports, we describe
methods for eliciting, indexing, and making stories available as instructional support for learning to solve problems. 相似文献

The aim of this study was to examine both positive and negative aspects of relationship quality in relation to condom use. Sexually active young women aged 14–18 years (n = 111; 34% non-white) were recruited from community clinics and schools in the Midwest USA and provided data via an online survey. The number of unprotected sex acts in the past month with the most recent male partner was regressed on relationship quality with that partner, adjusting for demographics and other characteristics. Negative relationship quality was associated with a greater number of unprotected sex acts among women reporting a low level of positive relationship quality and among women taking hormonal/IUD contraception. Positive relationship quality was associated with unprotected sex among women who reported multiple partners in the past month. Both positive and negative aspects of relationship quality may confer risk for unprotected sex. This risk appears to be modified by patterns of contraceptive use and other sexual behaviours. Health professionals and sexual health educators may be more effective in promoting condom use if they ask questions about both positive and negative aspects of young people’s relationship quality and tailor their conversations based on the responses received. 相似文献

This study investigated potential differences in inductive behavioural and verbal strategy-use between children (aged 6–8 years) from indigenous and non-indigenous backgrounds. This was effected by the use of an electronic device that could present a series of tasks, offer scaffolded assistance and record children’s responses. Children from non-indigenous ethnic backgrounds, starting at a lower level, profited as much from dynamic testing as did indigenous children but were unable to progress to the standard of this latter group. Irrespective of ethnic group, dynamic testing resulted in greater accuracy, fewer corrections, and reduced trial-and-error behaviour than repeated practice. Improvements in strategy-use were noted at both the group and individual level. After dynamic training, children from both ethnic groups showed a superior capacity for inductive reasoning although indigenous children subsequently used more inductive strategies. The study revealed individual differences between and within different ethnic groups and variability in the sorts of help required and subsequent strategy progression paths. 相似文献

Although instructional explanations are commonly used to introduce learners to new learning content, previous studies have often shown that their effects on learning outcomes are minimal. This failure might partly be due to mental passivity of the learners while processing introductory explanations and to a lack of opportunity to revise potential misunderstandings after working on introductory explanations. Against this background, we provided learners with two instructional support measures to optimise the introduction of new principles and concepts by providing instructional explanations in the domain of management theory: (a) prompts designed to induce inferences that are focused on the central content of the explanations, and (b) remedial explanations that are adapted to the learners’ knowledge gaps. We tested their effects in a 2 × 2 factorial experimental design with the following factors: (a) prompts designed to induce focused processing (with vs. without), and (b) remedial explanations (adapted vs. random). The participants consisted of 80 psychology students. We found that the prompts fostered both the share of deep-oriented processing and the acquisition of conceptual knowledge. The beneficial effect of prompts on conceptual knowledge was mediated by the number of inferences that learners generated in response to the prompts. In addition, we found that prompts also fostered the instructional efficiency of providing instructional explanations. The provision of adapted remedial explanations, however, fostered neither deep-oriented processing nor the acquisition of conceptual knowledge. We conclude that prompts designed to induce focused processing can foster deep-oriented processing as well as both the effectiveness and efficiency of learning from instructional explanations. 相似文献
