Definitions for the terms open-ended, problem solving, and investigations are considered. The interaction between these terms and teaching styles are discussed. Student influences over the learning process in this type of investigation are examined. (CW)

Describes a study in which elementary school children received different types of instruction about terminology used in explaining the water cycle. Results indicated that the group of students receiving hands-on instruction demonstrated a better understanding of the terms than did the other groups involved in the study. (TW)

Reports on a study of Canadian upper secondary science students' achievement of the concept of proportion. Results indicated that, in classes where the proportion content was emphasized by the teachers, higher achievement was demonstrated. (TW)

This article takes a critical look at practical work in school science and the often extravagant claims that are made for it. A case is made for a more rigorous, theory-driven approach to practical methods. (Author/CW)

Some observations of general progress and of gender-related differences in achievement when using construction sets in the early years are presented. Included are the results of two studies which examined the use of Lego construction sets by children age six to eight. (CW)

This study was designed to determine if the final grade in college biology at a suburban community college was a true measure of student's knowledge. One hundred and seventy undergraduates taking a semester course in biology took part in the study. This population was randomly separated into a control, placebo, and experimental group. The progress…

The reviews of articles contained in this issue have been grouped into those dealing with research related to cognitive development and to instruction. In addition, seven science education researchers have provided responses to critiques of their published research. Included are: (1) an analysis of an article designed to persuade researchers to…

A functional paradigm was used as a means of interpreting why teachers and classrooms function as they do. An assessment of the nature and sources of the functional paradigms of high school biology teachers was the major consideration of this study. A population of 28 experienced high school biology teachers recognized for exemplary teaching…

Some researchers have argued that it is important to match teaching styles with students' learning styles, although a relatively small amount of research has been done on learning styles in science. This study focused on the differences between male and female secondary school chemistry students in an effort to determine the relationship of gender…

Reports on a study which investigated the effects of having students analyze circuits in the laboratory compared with troubleshooting from homework problems. Results indicated that laboratory experiences provide a richer learning experience than lecture and homework alone. (TW)

Improvements in the mechanism of the whirlybird used in the Science Curriculum Improvement Study (SCIS) unit "Subsystems and Variables" are presented. Variables which can be investigated using this device are discussed. An illustration of the improved device is provided. (CW)

Cites the misconceptions that students beginning the study of electric circuits often have about electricity. Explains the use of capacitors with circuits of batteries and light bulbs to introduce electrostatic forces and help to alleviate the problem of misconceptions. (RT)

Four reports are presented including "Alternative Approaches to Assessment of Practical Work in Science"; "Introducing Multicultural Science Teaching to a Secondary School"; "A Case Study on the Relative Performance of Boys and Girls in Chemistry Part II"; and "An INSET Technique--Developing a New Consensus." (CW)

One of the primary goals in many teacher education programs is to design and to implement specific courses, strategies, and methods that promote positive attitude toward science and science teaching among elementary education majors. This paper describes the effects of a biology content course, patterned after innovative elementary school science…

The Partners in Elementary Science (PIES) program of the National Science Foundation (NSF) is a model Teacher Enhancement project. Its goal was to develop and test a program to help elementary teachers strengthen their science teaching by addressing areas of need, specifically teachers' confidence in teaching inquiry science and helping teachers…
