Discusses current views on problem solving in the workplace, and identifies five areas for consideration: (1) knowledge representation; (2) verbally teaching strategy components of the skill--versus the learner acquiring it inductively through practice; (3) the principles of teaching procedures; (4) how to construct simulations; and (5) weighing…

The DNA triplet code also functions as a binary code. Because double-ring compounds cannot bind to double-ring compounds in the DNA code, the sequence of bases classified simply as purines or pyrimidines can encode for smaller groups of possible amino acids. This is an intuitive approach to teaching the DNA code. (Contains 6 figures.)

Instructional resources that employ multiple representations have become commonplace in mathematics classrooms. This study will present computer software, LaborScale which was designed to improve seventh grade students' word problem-solving skills through computer-based multiple representations including graphic, symbolic, and audio…

Proposes to strengthen the theoretical basis supporting hypermedia computer-assisted language-learning (CALL) authoring by initiating a requirements analysis based on contextualized conceptual and mental models, presenting the theoretical dimension of knowledge representations within the authoring process and applying the theoretical approach to…

Research in the area of knowledge-based tutoring systems (KBTS) and intelligent tutoring systems (ITS) has great implications for computer applications in education and training. In a KBTS, course material is represented independently of teacher procedures, so that problems and remedial comments can be generated differently for each student. Such…

Recursion is a central concept in computer science, yet it is difficult for beginners to comprehend. Israeli high-school students learn recursion in the framework of a special modular program in computer science (Gal-Ezer & Harel, 1999). Some of them are introduced to the concept of recursion in two different paradigms: the procedural…

This article describes the PROVE strategy, which provides students with learning disabilities with a procedure for naming a concept, providing evidence (both why and how), and defending it. Research results are presented that indicate students with (n=12) and without (n=26) disabilities benefited from the PROVE strategy. (Contains references.) (CR)

We developed web-based modules addressing fundamental concepts of introductory biology delivered through the LON-CAPA course management system. These modules were designed and used to supplement large, lecture-based introductory biology classes. Incorporating educational principles and the strength of web-based instructional technology, choices…

Provides brief history of Structural Communication (SC) methodology and discusses its use for teaching eighth-grade literature. Examines strengths and weaknesses of SC in print and hypermedia formats, and discusses the computer-based implementation of this participatory method of instruction. (JKP)

The ultimate aim of this research is to specify and implement a general authoring framework for content and knowledge engineering for Intelligent Educational Systems (IES). In this context we attempt to develop an authoring tool supporting this framework that is powerful in its functionality, generic in its support of instructional strategies and…

This study examined the use of concept maps for Web-based applications in higher education. The purpose of the project was to design concept maps that could serve as prototypes for navigating and searching Internet resources. It also explored the value of concept mapping as a method of bibliographic retrieval for the ERIC database. Following an…

This study explored computer-based image processing as a study strategy for middle school students' science concept learning. Specifically, the research examined the effects of computer graphics generation on science concept learning and the impact of using computer graphics to show interrelationships among concepts during study time. The 87…

Praises, defends, and attempts to explain the unique characteristics of the lecture teaching method as practiced by Soviet educators. Firmly committed to the lecture method, Soviet educators refined this technique to the level of dazzling verbal performances complete with syllogisms, elaborately constructed arguments, and a touch of theater. (MJP)

Examines some limitations of online course delivery and management systems in terms of the range of pedagogies they support, and explores the effects of a distance learning pedagogy that emphasizes alternative forms of knowledge representation, authentic forms of assessment, and use of distributed tools on students outcomes and student perceptions…

The rapid growth of multimedia computing and the Internet, and the entrance of the commercial sector into information and the education sector previously dominated by academic interests, have raised the stakes for arts and humanities computing. In addition, ongoing reductions in funding for arts, humanities and educational research have made it…
