The role of the science teacher is essential in determining the quality of the school science program. When teachers are aware of the relationship between science and society, they can relate classroom learning to practical application. This results in more positive student attitudes. The continuous evolving of scientific knowledge requires…

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 Learning in Science Project has adopted the view that science teaching might be improved if teachers can be given some appreciation of students' views of the world and the beliefs, expectations, and language that learners bring to new learning situations. This investigation looks at the topic of soil, one of the basic resources of New Zealand…

The Learning in Science Project (Primary)--LISP(P)--investigated the questions and explanations primary children have about spiders. The data comprise 112 questions and 104 explanations (included in appendices) offered by children after being shown a picture of a spider. Additional data were collected during individual interviews with 18 students.…

The Learning in Science Project (Primary)--LISP(P)--investigated the ideas and interests about spiders held by 8- to 10-year-old children. Data included 303 questions--and answers to some of the questions--about spiders obtained from children in four classes and from responses obtained during individual interviews with 10 children from each age…

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…

Describes a simple high-performance liquid chromatography experiment for undergraduate biochemistry laboratories. The experiment illustrates the separation of polypeptides by a step gradient elution using a single pump instrument with no gradient attachments. Discusses instrumentation, analysis, a sample preparation, and results. (CW)

Reports the results of a survey of 70 experienced primary school teachers in Australia designed to explore respondents' concepts of technology and their attitudes about curriculum change. Discusses the implications of their findings on technology curriculum improvement. (CW)

Examines ways in which description and explanation are used in science teaching, including word usage and the role of activities. Considers the desirable characteristics of explanation for teaching purposes. Raises major questions about explanation in science education. Shows the need to make a clear distinction between description and…

Calls for differentiating between three kinds of studies of students' conceptions in science, namely descriptive studies, explanatory studies, and studies attempting to foster conceptual change. Cites the literature about student perceptions and science instruction. (TW)

Reports on a study into the relative importance of the four goal clusters of Project Synthesis as perceived by members of service clubs and community groups. Results indicate that although the importance of science for further studying of science remained constant from 1976-1986, significant increases occurred in the importance of science in…

Addresses the status of engineering education for women. Discusses the changes related to both the image of women and the engineering profession over the past 15 years. Assesses how computer-aided engineering has made engineering attractive to women today. (TW)

Determined which of 10 rational thinking powers are measured by 12 commercially-available standardized science tests. One result reported is that 90 percent of the test items required only recall. The conclusion was drawn that the producers of standardized tests are not concerned with measuring student achievement of the rational powers.…

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)

The construction and use of an instrument to monitor ultraviolet radiation from the sun are discussed. A diagram of the ultraviolet-B radiometer which is connected to a digital voltmeter is provided. (CW)
