Investigates the effect that manipulation of the extent of formal reasoning required for solving chemistry problems has upon student performance, and presents a cognitive model for the qualitative analysis of that effect. Concludes that the developmental level of students is the most important predictor of problem-solving success given significant…

A model for problem solving stressing both psychological and cultural influences is presented. This model is based on the analyses of how graduate students (n=10) solve organic synthesis problems, along with two models of problem solving and a constructivist epistemological stance. (KR)

The uses that chemistry students (undergraduates, postgraduate, and trainee teachers) make of analog models when relating equations to projects were identified. Although only a restricted use of such models were found, and for none of the reasons valued by practicing chemists, patterns were identified. The implications for chemical education at…

Implications for science curricula and instructions of new perspectives on scientific knowledge, on nature of evidence, and on how knowledge changes are considered. Argues that much of science education is mired in positivist assumptions and suggests ways in which science instruction can promote a more appropriate epistemological attitude and…

This study investigated the long-term impact of the Master of Science Degree in Creative Studies at Buffalo State College (New York) on the personal and professional lives of 38 graduates. Results indicated that graduates have integrated their knowledge of creative problem solving into both their professional and personal lives. Six tables detail…

Examines research literature and schematic models associated with the expert-novice model in cognitive psychology. Describes a model for rendering expertise in problem solving within economics. Reports that a preliminary study indicates that this model effectively rendered both expert and novice problem solving in economics. (CFR)

This paper reviews 25 studies of intervention research in mathematics with subjects classified as mentally retarded. Research has primarily been conducted in three areas: basic skills and concepts; rule learning and problem solving; and applications, including time, money, and measurement skills. Results are discussed in relation to instructional…

Definitions for the terms open-ended, problem solving, and investigations are considered. The interaction between these terms and teaching styles are discussed. Student influences over the learning process in this type of investigation are examined. (CW)

Purpose: This paper aims at presenting the theoretical concepts of the transdisciplinary case study approach (TCS), which is a research and teaching approach developed and elaborated at the Swiss Federal Institute of Technology (ETH), as a means of transition support. Design/methodology/approach: The paper reveals the historical roots of case…

There is a need to integrate the segregated perspective underlying research on scientific conceptions. Insights from scientists can provide information about the essential components of ideal knowledge. The purpose of this study was to investigate how researchers and teachers deal with scientific explanation. Three research physicists and five…

This study examined achievement differences between algebra students taught with the non-traditional textbook developed by Saxon and those taught with a "traditional" textbook by Dolciani. Student absences, rate of turning in homework, and ability level were considered, as well as teachers' comments. One Algebra I section in each of…

A study investigated developments in reasoning and memory as reflected by the discovery strategies of children taking part in a manipulative categorization and recall task. A total of 40 children (8 each of 18, 24, 30, 36, and 42 months of age) participated. Stimulus materials consisting of blocks, toy plates, discs, and plastic trees were…

Research on gender differences in group performance suggests that males excel at brainstorming while females excel at human relations and integration. To investigate the relations among gender, interaction style, and task performance, 264 college students (130 female, 134 male) worked in three person same sex groups on a production task which…

A conference in June 1978 brought together approximately 50 faculty from various American universities to discuss issues related to cognitive process instruction. This book contains the papers from that conference, focusing on recent, innovative approaches to cognitive process instruction and recent research studies on thinking skills that have…

The purpose of this study was to look intensively at two aspects of mathematics instruction--development and practice. It contrasted the Direct Instruction approach to the development phase of teaching problem solving with a Traditional approach taken from the teachers' manual of four widely used basal textbooks. Seventy-three fourth graders…
