Current theories and models of education often argue that instruction is best administered when knowledge is situated within a context. Problem-based learning (PBL) provides an approach to education that has particularly powerful affordances for learning disciplinary content and practices by solving authentic problems within a discipline. However,…

Our study focuses on the correlation of concept map (CMap) structures and learning success tested with short answer tests, taking into particular account the complexity of the subject matter. Novice sixth grade students created CMaps about two subject matters of varying difficulty. The correlation of the complexity of CMaps with the post-test was…

Our research aims to identify domain-specific similarities and differences of externalized cognitive structures. Cognitive structure, also known as knowledge structure or structural knowledge, is conceived as the manner in which an individual organizes the relationships of concepts in memory. By diagnosing these structures precisely, even…

Essays are an important measure of complex learning, but pronouns can confound an author's intended meaning for both readers and text analysis software. This descriptive investigation considers the effect of pronouns on a computer-based text analysis approach, "ALA-Reader," which uses students' essays as the data source for deriving individual and…

Examines the place of mental models in the process of knowledge construction, particularly by the relationship between mental models and computer models in that process. Analyzes and discusses children's use of spreadsheets to build their own computer models. Suggests that the process of building models on a computer may provide direct support to…

This paper provides practical advice for making online discussions educationally durable. This advice focuses on all stages of online discussions from designing the assignment guidelines through summative evaluation. While this practical advice is grounded in the author's experience, it is more substantively grounded in a framework defining…

As teachers begin to implement mathematics curricula that capitalize fully on computing technology and that are focused on concepts and applications instead of on execution of by-hand symbolic manipulation routines, their well-established routines of thinking about mathematics and its teaching no longer apply in seamless fashion. This case study,…

The Educational Technology Center (ETC) Complex Systems Project was initiated to explore ways of using computers to help students understand systems which have often proven too complex for most high school students to understand. Preliminary work concentrated on the cognitive processes involved in modeling simple systems. This paper describes an…

Explores what kinds of calculus-related insights seem to typify calculus-related reasoning. Introduces "qualitative calculus" in which learning is focused on synthesis. Discusses the resemblance and difference between traditional calculus and qualitative calculus, advantages of learning qualitative calculus, and how understanding qualitative…

The reviews of articles contained in this issue have been grouped into those dealing with research related to cognitive development and to instruction. In addition, seven science education researchers have provided responses to critiques of their published research. Included are: (1) an analysis of an article designed to persuade researchers to…

The mathematical experiences of elementary students often focus on memorizing facts and rules as opposed to making sense of the subject and developing problem solving skills. Students spend large amounts of time processing, memorizing and sorting collections of data which are tasks well performed by computer technology. To correct this situation,…

At Canada's University of New Brunswick (UNB), adult educators and computer experts jointly identified criteria for designing UNB's new Internet-based distance education delivery system called PSyCo (Presentation System for Courses). The 10 criteria that became the PSyCo blueprint were based on principles from three areas: architecture and design,…

Computer-mediated communication (CMC) technologies are becoming increasingly important components of online educational environments (Romiszowski & Mason, 2004). The online discussion forum that is a significant component of many web-based courses is one type of CMC. Instructors and students rely on these asynchronous forums to engage one another…

One of the most common misconceptions about probability is the belief that successive outcomes of a random process are not independent. This belief has been dubbed the "gambler's fallacy". The belief that non-normative expectations such as the gambler's fallacy are widely held has inspired probability and statistics instruction that attempts to…

New electronic technologies provide powerful tools for managing and processing the rapidly increasing amounts of information available for learning; teachers, however, have often been slow in integrating computers into the curriculum. This study addresses the question of how prospective teachers construct affective and cognitive models about…
