An approach to teaching electrochemical driving force that helps students comprehend the forces that govern ion flux across biological membranes and sets the stage for more elaborate analysis of biochemical signals is presented. Background information and two sample problems and answers are included. (KR)

A project that introduced scientists to students and engaged students in creative scientific activities is described. Students were asked to help scientists identify patterns on the wing of a species of fruit fly. A combined research/education program is recommended. (KR)

Examines issues surrounding socioethical topics. Argues that professional responsibility operates at three distinct but interconnected levels: individual (moral-philosophical), professional (sociological), and societal (multidisciplinary). Argues that the nature of sociology inevitably leads to facing ethical issues as professional rather than…

Review of experimental evidence concerning the effectiveness of problem-based learning suggests that the approach may not improve content-free problem solving; may initially reduce learning levels but fosters long-term retention; may enhance transfer of concepts and integration of concepts into clinical problems; enhances intrinsic interest of…

Presents several problems that use calculator or computer-generated graphs of the absolute value function as related to the maximum and minimum functions to illustrate the statistical concepts of range, median, mean, and variance. (MDH)

Describes a course designed to teach the relationship between science, agronomy, and society. Includes course and class description, course content, and evaluation of the course. (11 references) (MCO)

A review of nine studies on the efficacy of metacognitive interpersonal problem-solving training with students who have learning and behavior problems found demonstrated cognitive gains but less success in demonstrating that such gains were subsequently applied to actual behavior or generalized to other social behavior. (DB)

Review of research and development on the design of computer-based simulation for diagnostic training highlights the development and evaluation of eight diagnostic training systems that explored the appropriate level of student modeling needed for technology training. Topics addressed include changes in interface design, displays, and system…

Describes an exhibit containing four basic demonstrations relating to center of gravity and rotational equilibrium. The demonstrations involve (1) the stack of bricks, (2) the double cone, (3) the spool roller, and (4) the platform balance. (MDH)

This article reports on answers by children (grades 1-9, n=83) to oral and written questions concerning the phase change from liquid to gas. The development of concepts was followed, proceeding from concrete to abstract ideas. Many students were found to experience difficulties in problem solving even though they may have had the necessary level…

Science-shy public served by science-shy Congress could threaten national and global survival. People will come to understand science and technology when actively experiencing these disciplines as they exist in reality; where they have power and beauty, rather than in educational frameworks; where they are often neutered. Fortunately, "real stuff"…

Two groups of adolescents (n=36) with learning difficulties in mathematics were taught problem-solving skills under two conditions: standard word problems or contextualized problems on videodisc. Both groups improved their performance, but students in the contextualized problem group did significantly better on the contextualized problem posttest…

Offers advice on crisis intervention for all people who provide social services to Head Start families. Defines the conditions that constitute a crisis, and provides an explanation of four crisis categories and how to assess them. Outlines the steps home visitors take in providing support to a family in a crisis situation. (TJQ)

Discusses the unique problems of accommodating the needs of mildly handicapped students in rural schools and the importance of collegial support in overcoming these problems. Describes peer collaboration, a method of facilitating collegial support and mutual problem solving. Summarizes research evaluating the effectiveness of peer collaboration.…

Describes the guess-and-check method and discusses the advantages of using computers to apply the methods to solve mathematics problems. Provides two examples that use BASIC programs to illustrate the method. (MDH)
