Investigated was the effect of concept mapping on science achievement. It was concluded that mapping concepts prior to, during, and subsequent to instruction led to greater achievement. (CW)

Presents six learning activities dealing with planetary motion, the launching of satellites, and Halley's comet, all of which utilize the three laws of Johannes Kepler. These three laws are discussed in detail, and answers to the activities are provided. (KR)

Problem-solving models in memories of 11 good and 12 poor novice first-year university students were studied. The students reconstructed physics problems seen briefly, relying on models in memory. Both good and poor students had models of problem situations at their disposal, but good students performed better than poor students. (SLD)

Presents a motion problem that students in a college physics class are asked to solve and later asked to continue to analyze until they have stopped learning from the problem or the problem itself is finished. (MDH)

Proposed is a scheme for concept development in teaching the topic of energy. Levels within the scheme are described, as well as their interrelationships and their relation to the student's own world. (KR)

Suggests that disinterest in physics occurs because students and adults can apply everyday concepts to solve problems without understanding the underlying physics concepts. Proposes Wagenschein's Exemplary-genetic Method to teach physics and illustrates the method with examples taken from history. (MDH)

Discusses the development and use of Personal Assistants for Learning (PALs) computer tutorials for teaching applications of Newton's Laws. Finds that the tutorials were nearly as effective as individual tutoring by expert teachers and considerably more effective than the instruction provided in a well-taught physics class. (Contains over 30…

Investigates variations in students' responses to lever problems across multiple assessment contexts and formats. Data sources include students' semantic maps, written responses to questions, and modeled solutions to practical problems. Contains 40 references. (DDR)

Presents the application of decision-theoretic technique to a computer-based tutoring system for elementary mechanics. Uses sound probabilistic reasoning and a student model to identify learners' misconceptions. Focuses on the integration of Bayesian belief networks, item response theory, decision analysis, and database management systems in…

Many proven research-based instructional strategies have been developed for introductory college-level physics. Significant efforts to disseminate these strategies have focused on convincing individual instructors to give up their traditional practices in favor of particular research-based practices. Yet evidence suggests that the findings of…

This issue of ENC Focus highlights laserdiscs and CD-ROMs that encourage students to raise searching questions, enter debates, formulate opinions, and engage in problem solving and critical thinking. The laserdiscs and CD-ROMs were chosen based on the criteria of instructional design, content, and interest. Items featured include: The Chemistry…

This paper reports a study designed to examine the types of behaviors students exhibit while conducting laboratory activities and assess the effectiveness of strategies students employ. The sample was 42 students enrolled in a physics lab section at a single university. Three types of data were collected: (1) observational data during the lab…

One approach to the study of problem solving is to observe how people with different skills (novices and experts) solve problems by collecting and analyzing protocols and formulating models to obtain solution processes. Individual differences are subsequently explained by the differences in the knowledge possessed, as embodied by the sets of…

A summer science camp was held in Korea for 30 ninth grade students gifted in science. Students were divided into three groups (physics, chemistry, and biology) for activities which included problem solving, brainstorming, and experimental work. The experiments of the physics group addressed the use of solar energy, the chemistry group focused on…

A set of computer implemented models are presented which can assist in developing problem solving strategies. The three levels of expertise which are covered are beginners (those who have completed at least one university physics course), intermediates (university level physics majors in their third year of study), and professionals (university…
