This article discusses problem solving and how science educators can integrate problem solving into their instruction. The Search, Solve, Create, and Share (SSCS) model was developed based on the findings of problem solving research. (YP)

This activity was created to address a lack of problem-solving activities for elementary children. A "monorail" activity from the Evening Science Program for K-3 Students and Parents program is presented to illustrate the problem-solving format. Designed for performance at stations by groups of two students. (LZ)

Seeks to remedy a lack of studies that make direct comparisons using specifically designed instruments. Builds upon a previous parallel study comparing the views of teachers from Spain and England on problem solving by examining pupils' opinions of problems and the difficulties they encounter when trying to solve them. (LZ)

Discusses a well-known optical refraction problem where the depth of an object in a liquid is determined. Proposes that many texts incorrectly solve the problem. Provides theory, equations, and diagrams. (MVL)

Presents John Collier's "Problem-Solving Loop" as a structure for finding the most acceptable solution to any problem. Describes a project that uses the problem-solving loop to analyze some problems outside the classroom related to kinematics and dynamics. (JRH)

Measured children's (n=182) competence at syllogistic reasoning and in solving a series of problems requiring inductive reasoning. Reports that syllogistic reasoning and inductive reasoning were significantly correlated with both simultaneous and successive synthesis. Provides a basis for understanding the roles of spatial and verbal-logical…

Differences in biochemical education for job qualification and education for career preparation are described. Asserts that educational changes are needed to prepare students for careers. To build career skills, the author argues there needs to be more small group work. (PR)

Modifications in content and structure of basic courses in biochemistry are suggested to amend insufficiencies in biochemical education. Presents information on how molecular cell biology course was designed and evaluated to promote self-study. Senior undergraduate tutors were novelty of the course. Students rated the course highly for being…

Describes a variety of projects that were used in a summer program for gifted high school students to help teach biotechnical concepts and applications. Presents six projects utilizing algae as tool for solving problems. Also presents five production-oriented projects with hydroponics and fermentation as research and development themes. (PR)

Two different methods of measuring the temperature of an incandescent lamp at various voltage levels are described. By observing the color produced at a particular voltage levels, the lamp's color as a function of temperature can be determined. Needed equipment include a variac, a voltmeter, and an ammeter. (KR)

Ways in which linear lesson sequences can be modified to provide increased opportunities for open-ended activities especially with problem solving are considered. Examples drawn from chemistry and plant reproduction, seeds, and germination are given. (KR)

Activities in which students determine the half-life of a substance using M&Ms, solve a crime using chromatography, and calculate the speed of a toy car are presented. The activities include the topic, an introduction, the time needed, a list of materials, safety precautions, procedure, analysis questions, and teacher's notes. (KR)

Alternatives to the traditional unknown tests that permit a clear and unequivocal differential identification decision between Bacillus subtilis and Bacillus megaterium are presented. Plates of Phenylethyl Alcohol agar with Blood (PEAB), slants of Bile Esculin agar and plates of DNA agar are used. The materials, methods, results, and conclusions…

The drawn ideas of inventors Edison and Bell are analyzed in a systematic way to help understand the inventive process and how inventors think. By storing sketches on a computer the researchers have been able to recreate the probable lines of reasoning used by the inventors. (KR)

Presents a lesson that introduces students to polarized light using a problem-solving approach. After illustrating the concept using a slinky and poster board with a vertical slot, students solve the problem of creating a polarized light show using Polya's problem-solving methods. (MDH)
