In recent years, a number of models concerning problem solving systems have been put forward. However, many of them stress on technology and neglect the research of problem solving itself, especially the learning mechanism related to problem solving. In this paper, we analyze the learning mechanism of problem solving, and propose that when…

Activity theory (AT) is a powerful tool for investigating "artefacts in use", ie, the ways technologies interrelate with their local context. AT reveals the interfaces between e-learning at the macro- (strategy, policy, "campus-wide" solutions) and the micro-organisational levels (everyday working practice, iterative change, individual…

This article describes challenges and benefits of modeling learner variability in Computer-Assisted Language Learning. We discuss the learner model of "E-Tutor," a learner model that addresses learner variability by focusing on certain aspects and/or features of the learner's interlanguage. Moreover, we introduce the concept of phrase descriptors,…

Examines similarities between performance technology and instructional technology, including a systems approach, reliance upon analysis, theoretical antecedents, causes of performance problems, and anticipating obstacles to the introduction of innovation. Goals, target, activities, deliverables, domain, vision, and futures are compared; and the…

A project to determine the level of development complexity necessary to produce cost-effective instruction is described. The project is designed to investigate alternative levels of instructional development complexity, how these different levels affect spending, varying degrees of student achievement associated with each level, and the time…

This paper proposes a context-driven model of instructional design incorporating constructivist-oriented methods and strategies for structuring meaningful, purposeful learning environments into the framework of a traditional systematic approach. An evaluation study is also presented that investigated the effects of implementing the context-driven…

Presented in this report is an extension of the feasibility and follow-up studies on computer-assisted instruction (CAI) in the U.S. Army's Basic Electronic Training Course. The report is oriented toward demonstrating the viability of CAI coping with a large block (102 hours) of material under real-time training conditions. This evaluation is a…

As a first step in a systematic approach to instructional design, an attempt is made to develop public linguistic systems which would permit a designer to communicate with his colleagues. Abstracting general principles of design from fields other than education, an organized body of instructional design concepts emerges. These concepts are then…

This book, which is intended for individuals involved in developing, delivering, and supporting human resource development (HRD) programs, discusses worldwide HRD trends that were identified in a study of the HRD practices in 35 countries. Chapter 1 discusses the importance of the HRD trends identified and explains how they were identified.…
