Reports on a study which tested eight categories of logical fallacies with secondary students, student teachers, and teachers from Australia, South Africa, and Israel. Results indicate that logical fallacies were exhibited by all the groups. Implications are discussed. (ML)

Discusses some of the difficulties of visualizing underlying geologic structural patterns by using maps or wooden blocks. Suggests the use of a modified layer cake to show dipping beds, folds, faults and differential erosion, as well as the relationships of stream valleys to outcrop patterns. (TW)

Describes a chemistry experiment dealing with hemoglobinometry that can apply to transition metal chemistry, colorimetry, and biochemistry. Provides a detailed description of the experimental procedure, including discussions of the preparation of the cyanide reagent, colorimetric measurements, and waste disposal and treatment. (TW)

Exposes concerns related to physics in the period of mandatory education levels. Discussed are primary science, the transition from primary to secondary, content and process, double award GSCE science, science and technology, and reform of GCE advanced level. Argues toward a reappraisal of the mechanism for curricular reform. (CW)

Presents distance learning as a possible solution to augment the content area knowledge of teachers that will be teaching coordinated science and discusses some of the problems inherent in such an approach. Outlines how the Physics for Science Teachers Project at Open University is seeking to address these problems. (CW)

Presents a hierarchical list of principles that can be used as a guide in the construction of more successful science programs that have scientific literacy for all as a goal. Lists affective goals for science education. Discusses the role of teachers' attitudes and expectations in teaching this type of curriculum. (CW)

Describes a laboratory activity that is adaptable to several levels of biology students. Discusses methods for obtaining hellgrammites, performing the experiment, and analyzing the data. Includes sample charts and graphs. (CW)

Described is a study designed to introduce students to the behavior of common invertebrate animals, and to use of the chi-square statistical technique. Discusses activities with snails, pill bugs, and mealworms. Provides an abbreviated chi-square table and instructions for performing the experiments and statistical tests. (CW)

Describes experiences with turtle graphics to demonstrate motion in a constant gravitational field. Provides the computer program and typical diagrams. (YP)

Introduces two hands-on experiences, related to rotational motion and moment of inertia. Discusses the experimental procedures and provides figure of apparatus. (YP)

Critiques five arguments cited in support of process science. Considers the problematic nature of the processes and consequent difficulties encountered in mirroring these processes. Suggests an alternative way of viewing physics education through a trio of types of knowledge which can be used as governing principles in shaping education. (RT)

Addresses the requirements of high school students and noncrystallographers in lectures on crystals, diffraction, and structure analysis. Discusses basic understanding and a sequence that addresses these requirements. Suggests visual and descriptive teaching methods used in this effort. (CW)

Describes a circuit by which capacitance and the dielectric constant can be measured. Shows the circuit diagram and the method to calculate these constants. (YP)

Overviews the "Nuffield Coordinated Sciences" program. Discusses the aim, coordination of content, presentation, and the writing timetable. (YP)

Refutes the view that two capacitors in series with a source of constant voltage carry identical charges. Provides experimental procedures to verify this claim. (YP)
