Presented are four activities which integrate mathematics and science activities involving problem-solving skills. Topics of activities include derivation of pi (3.14), determining the volume of a bell jar, estimation skills, supplementary exercises using geometric and metric system tables, general laboratory exercises, and supplemental problems.…

Describes the development of a systematic instrument for assessing the impact of an environmental science course on students' behavior outside school. Students in an inquiry-oriented experimental curriculum significantly increased their leisure time activities in environmental science over students in traditional classrooms. (DS)

Reviews results of a California trial concerning the teaching of evolution in public school classrooms. Also lists recent legislation in the states of Florida, California, Minnesota, South Dakota, Kansas, Illinois, Iowa, Texas, and Arkansas. (CS)

Analysis of multivariate aptitude-treatment-interaction data is discussed. Analysis procedures are illustrated using data from a science education study to describe the interaction between student reading ability and the time allowed in an individualized instructional approach for multiple achievement and attitudinal outcomes. (Author/RL)

Determined the degree to which classification of students (N=512) as formal or concrete based on three Inhelder tasks administered by clinical interview method was mirrored by Longeot and Karplus-Lawson-Renner (KLR) classifications. Results indicate that Longeot and KLR differentiate between concrete/formal operations and are discussed from…

Poor behavior in one of 12 mixed-ability chemistry classes led to a stigma attached to it by school staff. Analysis of examination marks indicates the reputation was not justified in terms of academic achievement, demonstrating the ease with which academic achievements can be hampered unwittingly by teacher prejudices. (Author/JN)

Inservice mini-courses using a learning cycle instructional strategy (exploration, invention, discovery) have been developed. A description of the mini-course format (compatible with inservice programs sponsored by school systems), sample outline, and list of courses developed (with themes of environmental science and/or energy) are included.…

Provides instructions and a list of materials needed to demonstrate: (1) a model of the quantum mechanical atom; (2) principles involved in metal corrosion and in the prevention of this destructive process by electrochemical means; and (3) a Thermit reaction, modified to make it more dramatic and interesting for students. (SK)

Water pollution curriculum units of four environmental secondary science programs in Britain, Germany, Israel, and the United States are examined. Comparisons reveal the use of quite different approaches in central topic selection, use of the laboratory and other media, controversial issues, and teacher-student roles. (CS)

Twelve court cases involving laboratory situations are reviewed in chronological order. Report includes five statements indicating when an instructor is not liable as well as guidelines to improve laboratory safety and provide some measure of liability protection for the instructor. (JN)

Provides rationale for and examples of a game (Mastermind) which fosters the development of a systematic approach to problem solving. Includes a brief summary of an experiment with 50 high school students indicating value of the game. (JN)

Describes a study which determined the prevalence of the non-Newtonian view among students (N=125) and to what extent their physics teachers (N=5) were aware of this prevalence. Includes methods used and summaries of typical responses to a paper-pencil, multiple-choice format questionnaire focusing on aspects related to force. (JN)

Following a description of the "options" component of the JMB A-level physics syllabus, teachers' responses to these options are summarized by considering the time taken to complete options, factors influencing choice of options, and options teachers felt they knew best. (JN)

Relationships between levels of classroom individualization (personalization, participation, independence, investigation, and differentiation) and seven science-related attitudes of junior high school students (N=712) were examined. The study also provided support for the reliability and validity of the two instruments used and for their general…

Refutes scientific creationists' arguments that the earth is less than 10,000 years old by presenting information related to the time scales for creation and evolution models, times from stellar distances, Kelvin's estimate of the earth's age, radioactive decay, radiometric dating, and the decay of the earth's magnetic field.
