Incident identification graphs can be used to diagnose areas of difficulty in a subject's problem-solving schema at the episodic level. In this study, 22 subjects (2 experts and 20 novices) categorized into five problem-solving groups (expert, high algorithmic/high conceptual, low algorithmic/high conceptual, high algorithmic/low conceptual, and…

A course, called Nature of Science, is described as developed over the eight years it has been presented to nonscience majors at a liberal arts college. The aims of the course are to show important ties between science and those disciplines in which nonscience students' primary interests lie; to develop in nonscience students the recognition that…

This study examines the changes in students' conceptual thinking and problem solving abilities. Conceptual thinking skills and problem solving abilities are important factors for medical school applicants as diagnosis and treatment procedures strongly depend on these skills. Underrepresented minorities in medicine is a concern in United States,…

Describes a University of Florida video tape which shows general background information on linear response, derives the standard additions equation, and provides detailed examples of its use with the incremental method of standard additions. (MVL)

Discusses a questionnaire sent to 763 Society for College Science Teaching members to identify problems of teaching nonmajors. Notes the questionnaire had a high return rate. Lists the eight major problems: post negative experiences; motivation; what to teach; abstractions; how to introduce relevance; staying power; inquiry material; and…

The purpose of this study was to examine in detail the experiences of non-major undergraduate students progressing through an introductory physics course taught in a four-year research university, to discover why the students have these experiences, and to uncover the consequences of those experiences. A theory was developed for relating…

The Multimedia Education Laboratory of the Chemical Engineering Department at the University of Michigan develops multimedia-based educational materials presenting difficult concepts and chemical engineering processes. Highlights include software developed for undergraduate courses; the Multimedia Encyclopedia of Chemical Engineering Equipment;…

Follows the increase of the pH in a solution of vinegar during neutralization with commercial antacid tablets. Provided are background information, equipment details, procedures, and details of the data analysis. (MVL)

Discussed is a method to teach undergraduate students how to complete a conceptual design. Presents three tools to use: (1) how to use order-of-magnitude arguments to simplify problems, (2) how to derive design heuristics, and (3) how to decompose large problems into a set of small, simple problems. (Author/MVL)

Learning science is complex and difficult for many students and their understanding of science concepts and processes may be inaccurate or lacking. In an effort to improve the science achievement of underprepared students enrolled in a general science course, an integrative instructional model, "Dimensions of Learning" was used. Since acquiring…

Presents a computer program for use in teaching ion speciation in soil solutions. Provides information on the structure of the program, execution, and software specifications. The program estimates concentrations of ion pairs, hydrolytic species, metal-organic complexes, and free ions in solutions. (Author/RT)

Presented is a blueprint for restructuring the first two years of the engineering curriculum. Four new concepts for the first two years are discussed: (1) the mathematical and scientific foundations of engineering, (2) fundamentals of engineering, (3) the engineering laboratory, and (4) the professional and personal enrichment program. (MVL)

Presents reviews of literature for the following areas: perceptions and attitudes; curriculum and instruction; women and minorities; and the physical environment, educational technologies and support services. (PR)

Graphs of objects in motion are frequently used in introductory high school or college physics courses since they offer a valuable alternative to verbal and algebraic descriptions by offering students another way of manipulating the developing concepts. If graphs are to be a valuable tool for students, then the level of the students' graphing…

Examines the differences between the expectations of high school teachers and college chemistry instructors concerning students who plan to study college chemistry. Focuses on questions dealing with knowledge of chemical concepts and skills using those concepts. A plan of action is suggested. (YP)
