Heuristic task analysis on e-learning course development: a formative research study     

Ji-Yeon Lee  Charles M. Reigeluth 《Asia Pacific Education Review》2009,10(2):169-181

Utilizing heuristic task analysis (HTA), a method developed for eliciting, analyzing, and representing expertise in complex cognitive tasks, a formative research study was conducted on the task of e-learning course development to further improve the HTA process. Three instructional designers from three different post-secondary institutions in the U.S. were selected for interviews. The interviews focused on three e-learning course development cases (one from each institution), and the participants were asked to articulate their underlying thoughts and principles for designing e-learning courses. Overall, the HTA process worked well in the sense that the study could elicit procedural steps and sub-steps involved in e-learning course development and heuristic knowledge with which the instructional designers performed each step. On the surface, the e-learning course development processes that the instructional designers used looked more alike than different, entailing major steps such as meeting with faculty, developing content, monitoring courses in progress, and debriefing the instructor and students. The underlying principles and knowledge that guided each instructional designer through the processes, however, were unique in that each instructional designer constructed her own heuristics to accommodate the myriad contextual factors that arose in her work setting. The study also discussed the challenge of identifying the simplest yet most representative e-learning course development case with multiple experts and suggestions for further improving the HTA process were also presented.

Results and interpretations are categorized as follows: a professional profile of respondents; member observations about ATTW and its activities (member participation, appraisal of benefits, and preferred topics for TCQ); and current issues and views of the field's future.  相似文献   

Children and mothers in war: an outcome study of a psychosocial intervention program     

Dybdahl R 《Child development》2001,72(4):1214-1230

The present study was designed to evaluate the effects on children (age: M = 5.5 years) in war-torn Bosnia and Herzegovina of a psychosocial intervention program consisting of weekly group meetings for mothers for 5 months. An additional aim was to investigate the children's psychosocial functioning and the mental health of their mothers. Internally displaced mother-child dyads were randomly assigned to an intervention group receiving psychosocial support and basic medical care (n = 42) or to a control group receiving medical care only (n = 45). Participants took part in interviews and tests to provide information about war exposure, mental health, psychosocial functioning, intellectual abilities, and physical health. Results showed that although all participants were exposed to severe trauma, their manifestations of distress varied considerably. The intervention program had a positive effect on mothers' mental health, children's weight gain, and several measures of children's psychosocial functioning and mental health, whereas there was no difference between the two groups on other measures. The findings have implications for policy.  相似文献   

Teaching Text Design     

Robert Kramer  Stephen A. Bernhardt 《Technical Communication Quarterly》1996,5(1):35-60

A growing body of literature defines a rhetoric of visible text based on page layout, typography, and the various design features afforded by page composition tools buitt into word processors and page design programs. Little has been written, however, about what a wriier needs to know about design and in what order. This article describes and demonstrates a scope and sequence of learning that encourages writers to develop their skills as text designers. It introduces relevant liierature that is helpful for such learning and it does so in an evolving format that displays visually what the essay discusses verbally.  相似文献   

Educational quality in economic development: Ten propositions and an application to the South Pacific     

Ken Gannicott  C. David Throsby 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1992,38(3):223-239

Over the last two decades, research into the role of education in economic development has begun to pay attention to educational quality and its effect on learning outcomes. In this paper recent research on educational quality is reviewed and its application to the island economies of the South Pacific is assessed. While there is considerable variation among the countries, the paper demonstrates the pervasive nature of school quality problems in the region. Those factors which have the greatest bearing on school quality in the region are isolated. These factors are: the quality of teachers; the availability of learning materials; initial instruction in the mother tongue; the quality of educational management; and curriculum reform. The paper concludes by arguing that strategies to improve quality will fail unless they recognise important complementarities between the factors determining quality.

Zusammenfassung In den letzten zwei Jahrzehnten hat man begonnen, die Forschung über die Rolle des Bildungswesens in der wirtschaftlichen Entwicklung eines Landes auf Bildungsqualität und ihren Einfluß auf die Lernergebnisse auszudehnen. In diesem Artikel werden die neuesten Forschungen über die Qualität der Bildung aufgegriffen und eine mögliche Anwendung für die Inselwirtschaften im Südpazifik diskutiert. Dieser Artikel weist auf die überall gegenwärtige Problematik der Schulqualität in dieser Region trotz erheblicher Unterschiede zwischen den Ländern hin. Man fand folgende dafür verantwortliche Gründe heraus: Lehrerqualität, Erhältlichkeit von Lernmaterialien, Erziehung in der Muttersprache, Qualität der Schulleitung und Reform der Curricula. Der Artikel schließt mit dem Argument, daß Strategien zur Verbesserung der Qualität keinen Erfolg haben werden, solange wesentliche Zusammenhänge zwischen den qualitätsbestimmenden Faktoren nicht erkannt werden.

Résumé Au cours des vingt dernières années, la recherche sur le rôle de l'éducation dans le développement économique a commencé à prêter attention à la qualité de l'éducation et à ses effets sur les rendements de l'apprentissage. Dans le présent article, on procède à l'examen de la recherche entreprise récemment dans ce domaine et à l'évaluation de son application aux économies des îles du Pacifique sud. Tandis qu'on note une variation considérable entre les pays, on démontre la nature diffuse des problèmes relatifs à la qualité des écoles dans cette région. Les facteurs qui ont la plus grande influence sur la qualité de l'école dans la région sont isolés: qualité des enseignants, existence de matériels d'apprentissage, enseignement initial dans la langue maternelle, qualité de la gestion de l'éducation, réforme du curriculum. Cet article conclut en arguant que les stratégies devant améliorer la qualité dans ce domaine échoueront à moins qu'elles reconnaissent les complémentarités importantes entre les facteurs qui déterminent la qualité.

Integrating Cognitive and Psychometric Models to Measure Document Literacy     

Kathleen Sheehan  Robert J. Mislevy 《Journal of Educational Measurement》1990,27(3):255-272

The Survey of Young Adult Literacy conducted in 1985 by the National Assessment of Educational Progress included 63 items that elicited skills in acquiring and using information from written documents. These items were analyzed using two different models: (1) a qualitative cognitive model, which characterized items in terms of the processing tasks they required, and (2) an item response theory (IRT) model, which characterized items difficulties and respondents' proficiencies simply by tendencies toward correct response. This paper demonstrates how a generalization of Fischer and Seheibleehner's Linear Logistic Test Model can be used to integrate information from the cognitive analysis into the IRT analysis, providing a foundation for subsequent item construction, test development, and diagnosis of individuals skill deficiencies.  相似文献
