Presents the application of decision-theoretic technique to a computer-based tutoring system for elementary mechanics. Uses sound probabilistic reasoning and a student model to identify learners' misconceptions. Focuses on the integration of Bayesian belief networks, item response theory, decision analysis, and database management systems in…

The Minneapolis Public School System has been implementing an intervention-based approach to special education placement. This Problem-Solving Model (PSM) was designed to de-emphasize the role of norm-referenced tests and to provide early instructional interventions. The basic outline of the PSM is to define the problem, determine the best…

This paper describes the design of a web-based learning module. The aim in the design was to operationalize the concepts of granularity, reusability, scalability, and interoperability as they relate to learning objects. The prototypical module was designed for contexts where identifying and solving ill-structured problems is relevant. The module…

Launching new or improved products to the market typically involves extensive collaboration within and beyond the enterprise. Succeeding in a customer-driven market economy demands the practice of simultaneous engineering. The standard engineering or engineering technology curricula continue to make efforts in providing students with opportunities…

In this article, the authors would like to look at a range of solutions submitted by Year 4-5 teams in the 2003 "Naturally Mathematical Challenge" to a question that involves no more than the numbers 1 to 6 and possible arrangements of them. In the context of other competition questions and in their elaboration of mathematical process,…

This study investigated how tacit knowledge was used by expert and novice principals during problem-solving situations. Through the use of a phenomenological, qualitative approach, novice principals were compared with expert principals as both went about their daily tasks of school leadership. Results of the study contribute to the research on…

Many researchers have described cognitive differences between gifted and average-performing children. Regarding strategy use, the gifted advantage is often associated with differences such as greater knowledge of strategies, quicker problem solving, and the ability to use strategies more appropriately. The current study used microgenetic methods…

Research in goal theory has often relied on the general linear model, ignoring some central assumptions of the theoretical framework under investigation. The purpose of the two studies reported here was to illustrate how the Rasch model can supplement traditional statistical analyses when evaluating the effects of goal orientations on persistence.…

We present COLLECT-UML, a constraint-based intelligent tutoring system (ITS) that teaches object-oriented analysis and design using Unified Modelling Language (UML). UML is easily the most popular object-oriented modelling technology in current practice. While teaching how to design UML class diagrams, COLLECT-UML also provides feedback on…

Public policy for agriculture and natural resources must change as farming and the use of resources change, but policy also changes to reflect new understandings. The new understandings that will shape future agricultural policy may not come from food producers or agricultural scientists, and may not assume that expanding production is the primary…

This paper presents a practice-based theory of administrative, supervisory, and organizational decision-making, which views the organizational decision-making process as a social enterprise. It also describes how to facilitate organizational change by promoting faculty involvement and shows how to increase the potential success of reform efforts.…

This book presents 20 projects for technology education students. The emphasis is on problem solving and hands-on learning through projects dealing with a wide variety of technologies/industries, including the following: robotics, information storage and retrieval, communications, transportation, electronics, manufacturing, construction, materials…

This book is designed to help students understand the nature of scientific inquiry by involving them in doing science rather than merely reading about it. The content of the text emphasizes science process skills, mathematical skills, and the use of theories and models that are fundamental for learning the various science disciplines. The…

This book shows how to use evaluation to find effective solutions. The first two chapters introduce evaluation as an administrative function at the school level. Chapter 1 draws on two kinds of literature--educational-administration literature (to survey administrative practices) and educational-evaluation literature (evaluation practiced by…

A methodological framework is presented for representing tradeoffs among alternative combinations of training and aiding for personnel in complex situations. In general, more highly trained people need less aid, and those with less training need more aid. Balancing training and aiding to accomplish the objectives of the system in a cost effective…
