Contradictory evidence has been reported on the effects of discovery learning approach and the role of instructional explanations. By manipulating the presence of instruction (verbal explanation) and transparency of problem structures, we investigated how effects of instructional explanations differed depending on the transparency of problem…

A series of studies conducted to identify the factors that block and unblock problem solving is described. Through the construction of an isomorph of the classic "water jar" problems developed by A. S. Luchins (1942) as a dynamic graphic micro-world, several factors involved in producing blocked states were identified. Subjects included…

Recent research has demonstrated that knowledge about specific instances may be of more relevance to reasoning than has previously been assumed. Students can rely on principles they have learned, or they can recall something similar previously experienced, and base the new prediction on it in an instance-based approach. Instance-based (or…

This study is one of several conducted by the authors in their investigation of the use of "higher order rules" in the solution of problems. The focus of the current experiment was determination of the compatibility of identified rules with the knowledge of average teenagers, and of the extent to which instruction in higher order rules…

This paper describes part of a course for college freshmen entitled "Computation, Reasoning, and Problem Solving," which uses the LOGO programming language to integrate computer programming skills, collaborative problem solving skills, and writing skills. Discussion of the computer programming component includes two of the LOGO problem…

A series of 13 questions is offered for sequencing student writing activities according to a problem solving model of the composing process. The questions are organized in a cyclical framework for approaching any problem solving task that writing students may face. The questions fall into four progressively developed categories, including…

This paper describes an approach to task analysis which seeks to identify potential sources of difficulty in the self-discovery of improved procedures by students who have been taught simpler procedures. The approach considers novices' procedures in terms of the changes needed to produce an expert procedure; the knowledge required to make those…

Discussed in this report is a technique used in cross-cultural research for measuring cognitive processes in children and youth. The research strategy aims at evaluating the subject's performances on problem solving tasks by having subjects become active agents in the discovery process while experimenters remain as passive and neutral as possible.…

A computer language that can be used by people of all ages, Logo allows children the freedom to direct their own learning. Integrating Logo into the curriculum provides students the opportunity to program a computer, to engage in logical, sequential thinking and planning, to solve problems, and to manipulate text, language, graphics, and music…

The Community-Based Report provides students in business communications classes with an authentic context for thinking and writing. Students are required to investigate and produce written and oral solutions to a problem experienced by a local corporation, business, governmental or not-for-profit organization. Students develop their own cases,…

This paper introduces an artistic model of planning and problem solving. The model is based on a case study of processes engaged in by a college art student during the course of producing a senior thesis in batik (a wax-resist fabric dyeing process). Based on the premise that knowledge of the creative process is essential to understanding the…

Secondary school and college students can learn how to shape thought through shaping language by using tagmemic heuristics. To approach writing as a thinking process, students apply three heuristics: one for identifying and stating problems, one for exploring problems, and one for evaluating hypotheses or solutions. Guided by a series of…

Open-ended learning environments (OELEs) provide contexts to support exploration, experimentation, and problem-solving. This paper creates a context for understanding the issues and challenges associated with the design and development of OELEs. Discussion first centers on characteristics of OELEs which differ from traditional learning…

This paper reports on a pilot study of 34 sixth-grade students engaged in mathematical explorations that was carried out in the context of a national Logo project in Costa Rica. Students worked in pairs investigating a mathematical microworld written in Logo. The investigation had three phases: (1) open exploration of the microworld, during which…

The achievement of bilingualism appears to have positive consequences for the bilingual child, enhancing universal aspects of cognitive functioning available to all normal children. However, little is yet known about the interaction between educational treatment and the input factors the bilingual child brings to the situation. Focusing on the…
