Results of a multiple choice instrument, (sample of convenience, n=45 education students), indicate that preservice and inservice science teachers had similar views. Views are classified as "Naive,""Has Merit," and "Realistic." The majority (79%) of the inservice teachers and the largest percentage of the preservice…

Describes a laboratory exercise that takes advantage of the abundant number of species of goldenrod galls that exist in the environment to explore a question concerning the behavior of the female gall-forming insects as they lay eggs on the goldenrod plant. (ZWH)

Presents information and data on an experiment designed to test whether different atmosphere compositions are affected by light and temperature during both cooling and heating. Although flawed, the experiment should help students appreciate the difficulties that researchers face when trying to find evidence of global warming. (PR)

Describes the design of a biochemistry course that uses problem-based learning. Provides opportunities for students to question, dispute, confirm, and disconfirm their understanding of basic concepts. Emphasizes self-correction through dialogue. Topics covered include amino acids, metabolic pathways and inherited disease, proteins, enzymes and…

Assesses students' learning of evolution by natural selection within four different sections of an introductory biology course where each section used a different combination of curricular materials and instruction. Reports that comparisons between sections support the use of paired problem-solving instructional strategy in conjunction with the…

Examines motivation in high school students' conceptual change about physics principles, and college students' motivation for biology learning. Finds grades and interest were important, but students did not report the importance of social support. Suggests similar motivations are important in both conceptual change and assimilation and help…

Describes a study of high school students' and chemistry teachers' understanding of the gas laws which focused on the application of scientific concepts in practical situations instead of mathematical calculations in theoretical situations. (Contains 13 references.) (WRM)

Describes a study of the similarities and differences in graph-related interpretations between scientists and college students engaged in collective graph interpretation. Concludes that while many students learned to provide correct answers to scientific graphing questions, they did not come to make linguistic distinctions or increase their…

Describes the development, implementation, and evaluation of a module called "Energy and the Human Being" within the framework of a program aimed at non-science-oriented students in senior high schools in Israel. Finds that students' attitudes toward science were positive and their understanding of the scientific concepts involved was…

Describes an assessment of science student teachers' knowledge of biological concepts performed before and after their one-year Post Graduate Certificate of Education (PGCE) course. Finds little improvement in subject knowledge following training or in subsequent teaching of the concepts during the PGCE year. Suggests ways to improve science…

Reviews approaches used in teaching seasons to elementary and middle school students over the past 200 years. Finds that the same diagrams have been used from the 1800s to teach about the seasons despite changes in the background knowledge of students and teachers, and changes in theories of teaching and learning. (Contains 24 references.)…

Presents the results of a study of elementary science teaching methods. Finds that teachers participating in the study always elicit children's ideas prior to science instruction, and thus consider student ideas to be important. Also finds that students perceived that their ideas were important whether or not the teachers addressed those ideas in…

Examines the effects of adding a prediction/discussion phase at the beginning of a three-phase learning cycle involving exploration, term introduction, and concept application. Finds that the instructional innovation produced significant gains relative to the use of process skills, logical thinking skills, science concepts, and scientific…

The reform documents of the 1990s stressed that science is not practiced by a rigid scientific method, but science texts continue to describe the process as if it were rigid and linear. The purpose of this investigation was twofold: (a) to explore middle school in-service teachers' perceptions of scientific methodology and (b) to explore ways in…

Educational technology supports meaningful learning and enables the presentation of spatial and dynamic images, which portray relationships among complex concepts. The Technology-Enabled Active Learning (TEAL) Project at the Massachusetts Institute of Technology (MIT) involves media-rich software for simulation and visualization in freshman…
