Presents a model for solving genetics problems when problem statements include information on which alleles are dominant/recessive and on what forms of a trait are coded for by the alleles. Includes procedural steps employed in a solution and conceptual knowledge of genetics/meiosis allowing students to justify what they have done. (Author/JN)

Skills needed for problem-solving are discussed. Examples of defining problems, questioning, observing, classifying, predicting, and confirming are provided. An overview of the Elementary Science Study (ESS) program, including a list of ESS units (grouped by subject matter), is also provided. (Author/JN)

Determined degree to which Malaysian biology teachers (N=26) perceived they understood and used inquiry teaching. Data indicated that these teachers perceived they had a moderate amount of knowledge about inquiry and occasionally used the 21 inquiry-related behaviors assessed by "A Generic Problem Solving (Inquiry) Model" (Hungerford,…

Suggests taking a relatively unsophisticated scientific theory and finding criticisms which could be leveled against it. Illustrates this instructional strategy by presenting a detailed criticism of the projectile theory of light. (SK)

Presents discussion on: (1) computer assisted synthesis in industry and academia; (2) computer applications to teaching organic synthesis; (3) a computer program (ORGSYN) incorporating reactions to synthesize aliphatic compounds; and (4) the design of a computer program as a heuristic device in an introductory organic course. (SK)

Reports on a study involving eighth grade earth science students (N=287) which indicates that a problem solving approach is useful in improving overall achievement, particularly in facilitating application of earth science subject matter. (CS)

Described is a model for planning and conducting an investigation designed to teach science process skills. Use of this model illustrates the generalizability of process skills and facilitates their inclusion in novel curriculum areas and beyond the classroom. (DS)

Discussed are science activities appropriate for middle school students. Considerations include the degree of abstractness of the concepts and the need for increased class time for explaining, discussing, and integrating students' activity experiences. (DS)

The French language article analyzes the Test of Science Processes and describes other measurements of the investigative skills of secondary students. It defines problem solving, scientific method, investigation (the preferred strategy for teaching high school science curricula), and two fundamental investigative abilities: observation and…

Presents a definition of problem solving and discusses process and stages. An outline is given of particular uses of problem-solving networks. (SA)

Discusses ways in which to help students solve problems effectively. On the basis of her observations of novice and expert problem solvers, the author suggests teaching the processes used by the experts directly to the students. (SA)

Activities used to teach optics to fifth and sixth graders are presented. Moon phases and solar and lunar eclipses are included. (SA)

Focuses on techniques of improving interaction within groups of children engaged in a classroom science activity. The role of the teacher is discussed as well as the positive outcomes of successful cooperation between children. (SA)

Discusses the dilemma case, a well-known method of case instruction in which a protagonist is thrust into the middle of a crisis and must make a decision. Enables students to gain an understanding of the issues and then suggest possible solutions to the dilemma. Develops students' critical-thinking skills and speaking abilities. (JRH)

Describes the use of supplemental instruction in an introductory chemistry course designed for freshman nursing students and explores its impact on student performance and response to the program. Results indicate a positive impact of supplemental instruction and its popularity with students. Contains 22 references. (JRH)
