The concept of hypertext was introduced by Ted Nelson in 1965, but only recently has the widely available technology caught up with the idea. The new generation of microcomputers featuring large internal memories, graphic interfaces, and large data storage capacities have made the commercial development of hypertext/hypermedia software possible. A…

This paper reviews empirical studies of the efficacy of the use of computer assisted instruction (CAI) in various settings, with particular attention to the use of CAI to teach mathematics skills and concepts. Studies using students at various ages and various subjects are considered, as are applications in which CAI was used as the primary…

Computer based instruction (CBI) is composed of individual frames viewed one at a time. Compared to a typical textbook, CBI restricts the adult learner's capacity to access information from different parts of the lesson and to view complex presentations. Designers of CBI must compensate for these limitations by making a concerted effort to…

Testing and evaluation are important components of effective instructional software development. Many evaluation approaches today are multifaceted, employing a combination of methodologies and multiple data collection techniques. In this paper, several approaches to evaluation are discussed. Computerized tracking systems, videotape recording…

This paper summarizes research in modern cognitive theory that relates to the role of computer drill and practice programs in learning and describes a prototype program that exemplifies recommended characteristics. Focus is on four major issues that are relevant to the design and optimization of computer drills: interference, spaced practice,…

This paper describes the creation and evaluation of a World Wide Web-based courseware module, using conceptual models based on constructivism, that teaches novices how to use the Internet for searching. Questionnaires and interviews were used to understand the difficulties of a group of novices. The conceptual model of the experts for the task was…

This paper speaks to the challenges, risks, and rewards of teaching about linear functions in a technology-rich environment from a constructivist perspective by describing a Foundations of Algebra class, which was designed and taught to junior high school students in such an environment in the summer of 1991. The design and implementation of the…

This paper demonstrates that the axis between cognition and multimedia language teaching is very short by introducing three fundamental concepts: (1) mediatizing, i.e., the direct use of any medium as a way of expressing oneself; (2) multimediatizing, i.e., the choice of a multimedia support to express a didactized informational content; and (3)…

This paper presents a method to help high school students with learning disabilities increase their vocabulary in preparation for college, including preparation for college entrance examinations such as the Scholastic Assessment Tests (SATs). The approach focuses on the use of elaborative techniques in which students actively generate meanings and…

Open-ended learning environments (OELEs) like microworlds have been touted as one approach for blending learning theory and emerging technology to support the building of student-centered understanding. The learning process involves developing a theory-in-action--an intuitive theory that is generated and changed by learners as they reflect upon…

This paper discusses four areas in the psychology literature that have important implications for the instructional design of microcomputer-based simulations. The first one examined is cognitive structures, and the following suggestions for instructional design are offered: simulations should be appropriate for students' level of understanding;…

This document contains the following full and short papers on cognition and conceptual change from ICCE/ICCAI 2000 (International Conference on Computers in Education/International Conference on Computer-Assisted Instruction): (1) "A Method of Creating Counterexamples by Using Error-Based Simulation" (Tomoya Horiguchi and Tsukasa…

High and low level questions as determined by a panel of evaluators were combined with corrective feedback and attribute isolation feedback to form four versions of a computer-based science lesson. The sample consisted of 154 high school chemistry students in a suburban high school. The primary hypothesis was that students who received high level…

This study investigated the relationships between hypermedia users' information processing styles and navigational patterns. Three aspects of navigational patterns were investigated: navigational depth patterns that reveal how comprehensively users access; navigational path patterns that display what sequences users follow; and navigational method…

The purpose of this study was to examine the effects of replacing multiple-choice and short-answer questions in programmed tutorial courseware practice interactions with learner-generated summaries on three types of verbal information learning outcomes. The study was designed to empirically investigate the claim that the level of mental processing…
