The Telemakus System builds on the areas of concept representation, schema theory, and information visualization to enhance knowledge discovery from scientific literature. This article describes the underlying theories and an overview of a working implementation designed to enhance the knowledge discovery process through retrieval, visual and…

Presents the problem of points and the development of the binomial triangle, or Pascal's triangle. Examines various attempts to solve this problem to give students insight into the nature of mathematical discovery. (KHR)

Presents materials and methods that maintain student interest and encourage them to think creatively, develop mathematical reasoning, and look at problems from different perspectives, all within an open-ended approach to problem solving. Includes questions for discussion. (KHR)

Explains the process of focusing on one critical reading strategy--questioning. Notes that the teacher first modeled questioning while reading a book aloud. Concludes that as students become full participants in questioning, they understand new vocabulary, enjoy reading, and solve their problems. (PM)

Examines the use of mathematics in a computer-aided design and manufacturing setting, whether this mathematics is related to school mathematics, how technicians understand this mathematics, and the role of technology in the technicians' mathematics-related problem solving activities. Focuses on technician's calculations of the interval volume of…

Discusses professional development intervention that attempted to start a professional community of secondary mathematics teachers through in-service work on mathematical problem solving and technology. Suggests that use of mathematical content explorations in professional development settings help mathematics teachers build professional…

Describes three inquiry-based activities designed for students to begin to understand complex environmental relationships in their own backyard. Includes investigations of ants, which allow students to establish a baseline survey of ant fauna, test the importance of ants in nutrient cycling and soil structure maintenances, and increase student…

Two experiments examined problem solving in 16-month-olds' adaptive locomotion (crossing bridges of varying width with/without handrail). Findings indicated that toddlers attempted wide bridges more than narrow ones. Attempts on narrow bridges depended on handrail presence. Toddlers had longer latencies, examined bridge/handrail more closely, and…

Discusses teachers' sensitivity in the context of young children's peer conflicts. Explains that young children need to experience their own actions as logical and sound and that they co-construct logic-in-action (procedural knowledge) long before they can verbalize their logic. Maintains that teachers who do not respect children's logic often…

Describes the angles-of-a-star problem designed to find the sums of the measures of the angles at the vertices of a five-pointed star. Shows that a good problem may have many correct solutions. (KHR)

This study documented one child's development of conflict resolution skills when a peer problem-solving model was used in a constructivist-designed classroom. Findings revealed that this child progressed from a power assertion style of conflict resolution to a more sophisticated form of negotiation. The study supports current thinking that young…

Describes the results of a controlled experiment that tested the effectiveness of Lord's teaching model in: (a) helping students achieve better grades on standard midterm exams; (b) developing higher level thinking skills; and (c) modifying attitudes towards biology at a large urban university. (Author/SOE)

Proposes an alternative strategy for teaching basic statistics to prospective and practicing school principals. A basic statistics course should emphasize exploratory data analysis, graphics, and report writing; illustrate statistical concepts using real-world data; stress descriptive statistical methods; and require students to learn all three…

Methods for teaching problem-solving strategies for word problems to students with learning disabilities are described in the context of the 1989 National Council of Teachers of Mathematics Curriculum and Evaluation Standards. Examples are given for using the specific strategies of diagrams, ratio equations, tables, and inverse operation…

A survey of graduate students enrolled in computer-mediated conferencing courses and a follow-up analysis of help seekers who used a dedicated hotline found that many students had encountered computer communication difficulties. Students varied in their ability to solve these problems and in their attitudes toward them. (Author/LRW)
