This paper describes the structure of the "Air Pollution Course", an environmental science laboratory course developed at the Science Education Laboratory of the Faculty of Primary Education, University of Athens, as well as the findings resulting from its implementation by pre-service elementary teachers. The course proposed in this…

Analyzes narrative essays--stories of rock formation--written by pre-service elementary school teachers. Reports startling misconceptions among preservice teachers on pebbles that grow, human involvement in rock formation, and sedimentary rocks forming as puddles as dry up, even though these students had completed a college level course on Earth…

The purpose of this study is to examine one possible source of misconceptions that are held by students of genetics--the teachers. Is there evidence to suggest that prospective biology teachers might have misconceptions about genetics and related concepts? If prospective biology teachers have misconceptions in genetics, how do these misconceptions…

Finds that only half of practicing science teachers and a third of pre-service teachers surveyed in Singapore agreed with statements that biological evolution has a valid scientific basis. (Contains 12 references.) (WRM)

Measures both teaching efficacy and the holding of specific alternative conceptions of preservice elementary teachers (N=619). Uses a survey to determine the relationship between teaching efficacy and certain alternative conceptions. Contains 77 references. (DDR)

Argues that there are only a few cases in which solubility and Ksp are related in a simple way. States that illustrations of the solubility product principle for one-to-one salts are adequate for students. Contains 23 references. (DDR)

Students are currently exposed to world environmental problems--including global warming and the greenhouse effect--in science classes at various points during their K-12 and college experience. However, the amount and depth of explosure to these issues can be quite variable. Students are also exposed to sources of misinformation leading to…

Identifies and describes misconceptions held by pre-service high school science teachers regarding three environmental issues: the greenhouse effect, ozone depletion, and acid rain. Indicates that many pre-service high school teachers possess an array of misconceptions about the causes and effects of each. (Contains 24 references.) (Author/YDS)

Argues that consideration should be given to whether teaching solubility product calculations is at all useful. Claims that experienced teachers seriously misunderstand and misuse solubility product calculations. (DDR)

Fourth-year university students (n=12) in a secondary-science-education degree program in Singapore were interviewed after demonstrations of five familiar chemical reactions. The majority of interviewees used perceptually-dominated rather than conceptually-dominated thinking and were unable to use scientific concepts consistently across the five…

Discusses the results of a four-year study of the conceptions of energy held by science teachers in training. Concludes that the group held a number of different alternative conceptual frameworks. Contains 20 references. (DDR)

This paper reviews the research on mathematics teacher education and mathematics education reform to provide a possible foundation for educating mathematics teachers in rural Appalachia. The paper takes the position that teacher change has certain characteristics and impediments that are not limited to any particular circumstance. Research on…

Summarizes a complex study of a science-teacher-education program whose goal was to graduate teachers who held conceptual change conceptions of teaching science and were disposed to put hem into practice. Concludes that there are influences on prospective teachers from their content coursework that have significant implications for how they view…

Introduces an issue that details a complex study of a science-teacher-education program whose goal was to graduate teachers who held conceptual change conceptions of teaching science and were disposed to put them into practice. Presents a conceptual framework for science-teacher education, and describes the context and major questions of the…

Explores high school students' and preservice teachers' knowledge of light, vision, and related topics before and after commonly practiced instruction. Suggests a hierarchical structure to represent the collective conceptual knowledge of students and teachers in terms of facets and schemes of knowledge. Makes suggestions for designing instruction…
