Reports data obtained from a sample of British adults on their knowledge of simple biological topics. Analyzes responses according to gender and educational background. Findings indicate that people with a non-science background responded similarly to those with a higher educational level. (ML)

Student knowledge in a subject area prior to and after instruction has traditionally been assessed by administering a pre- and post-test, usually multiple choice, though recent studies criticize the use of even the best-constructed multiple choice tests. This study assessed college freshmen's knowledge before and after a laboratory experience in…

The article presents a step-by-step guide to choosing and using performance assessment to determine what students know and can do in science. Performance assessment allows teachers to measure what students know by watching what they do. An example of performance assessment in action is included. (SM)

Investigates how 20 English primary teachers understand the concepts of force and gravity. Uses the interview about instances technique. Finds teachers' views of these concepts are not in accord with accepted scientific interpretations but similar to those of children's views. Discusses implications of the findings. (NL)

This practicum was designed to develop more positive attitudes toward science and to increase students' knowledge of science by providing supplemental hands-on activities. Second grade students were surveyed at the beginning of the school year and then were retested after participating in hands-on activities from 12 learning centers. The…

One goal of science educators is to help students to understand the nature of scientific knowledge and reasoning. Reported are ideas related to what junior high students do, can and should know about the nature of science and the use of technology in imparting such knowledge. The studies reported in this document are designed to probe junior high…

Proposes methods by which laboratory practical exams may be structured to assess outcomes from laboratory instruction. Presents eight general considerations for writing and using practical exams. Describes four example laboratory exams involving a box camera, circuit boxes, floating objects, and light. (MDH)

An analysis of science teacher's knowledge of specific biology and physics topics and the effects of this knowledge on their planning for instruction and on simulated teaching are discussed in this report. Six experienced secondary school teachers participated in the study. Each teacher's knowledge of a biology topic and a physics topic was…

Compares performances of students on gas-law problems that require two distinct approaches, either the algorithmic technique or the conceptual gestalt. Indicates that student effectiveness is considerably different utilizing each approach and that training or experience with the algorithm process should not be expected to facilitate the…

Designed to test the effects of knowledge acquisition on attitude formation and change, this study investigated whether knowledge-oriented instruction would have a different effect on students' nuclear attitudes than attitude-oriented instruction. High school students (N=331) from six schools who had not studied nuclear energy in any class or…

This investigation was conducted to determine the effects of a 10-day summer workshop using the Concerns Based Adoption Model concerning science technology and society (STS) topics and methods of classroom implementation on the knowledge, attitudes, and stages of concerns of the participating secondary inservice teachers, as well as student…

Designed to focus on teaching for higher-level cognitive learning, this study measured student perceptions of psychosocial aspects of their classroom learning and involved a team of six researchers. The study consisted of an intensive 10-week investigation of two above-average science teachers in a suburban high school in Perth, Western Australia.…

Reports a study designed to compare science and nonscience Indonesian high school students' (n=400) energy-related knowledge and their attitudes toward energy conservation. Results indicated that (1) students in general have unfavorable attitudes toward energy conservation, and (2) nonscience students are less knowledgeable about energy-related…

This study was conducted to examine the basic conceptual knowledge and understanding of physics possessed by students enrolled in introductory physics, mechanics and waves and optics courses at John Abbott College (JAC). The study used a 36-item multiple-choice test of physics preconcepts developed by Halloun and Hestenes. The Halloun and Hestenes…

Describes three perspectives from which middle school teachers can plan laboratory activities for the purpose of improving students' scientific literacy. Perspectives are the learning cycle approach categorizing activities by stages of development; problem-solving skills approach categorizing activities according to the amount of teacher control;…
