Focuses on a small group of middle school students as they develop understanding of emergent systems, which are notable in that macro-level properties emerge as the result of micro-level interactions between system components. Describes students' initial understanding of emergent systems as well as their thinking. (Contains 35 references.)…

Examines the effects of open inquiry instruction on low achieving, marginalized high school students. Involves students with long histories of scholastic failure in question generation, experimental design, and argument construction as part of their General Science course instruction. Compares students' entrance and exit interview responses which…

Analyses the ways in which university-entrant science students carry out and communicate experimental activities, and identifies a model to explain characteristic communication practices. Observes the investigative strategies of participant students who have a lack of experience with laboratory work and scientific writing. Uses laboratory reports…

Explores the types of written questions students ask after reading one or more chapters from a textbook and investigates students' ability to improve their questions during the course of a single semester. Examines two comparable populations, undergraduate students who were taught in the traditional lecture format and students who were taught in…

Discusses the need for science educators to understand the relationship between cultural and socioeconomic issues and the science education of inner-city students. Studies a homeless family in a major metropolitan area in the Northeast and frames the analysis through the pedagogical questions of representation of science through culture,…

Investigates whether studying about the nature(s) of science contribute to a prospective teachers' effectiveness as a teacher. Argues that a course studying the cultural wars over science contributes to prospective teachers' professional growth because it elicits tacit beliefs about school science as it introduces more complex understanding.…

Examines the beliefs and practices of a high school biology teacher who developed an inquiry-based learning environment. Studies the process of day-to-day instruction, and analyzes classroom lessons and field trips to answer the question, How does a teacher establish an inquiry based learning environment? (Contains 36 references.) (YDS)

Uses two assessment methods to measure student competence in conducting scientific inquiry. Investigates 32 high school students for a relationship between scientific inquiry capability and success in making discoveries. Defines scientific inquiry, scientific discovery, and the relationship between these two concepts. (Contains 70 references.)…

Employs hierarchical linear modeling to examine the relationship between professional development and the reformers' vision of teaching practice. Indicates that the quantity of professional development in which teachers participate is strongly linked with both inquiry-based teaching practice and investigative classroom culture. (Contains 39…

Investigates the effect of instruction to improve the reasoning skills of undergraduates majoring in education. Results indicate the lack of proficiency in formal reasoning by undergraduate education majors in the areas of proportional, probabilistic, and correlational reasoning. Also indicates that deficiencies in reasoning ability in these areas…

Extends prior theory and research by postulating the existence of an intermediate class of concepts called 'hypothetical'. Investigates the hypothesis that three kinds of scientific concepts exist by constructing and administering a test on concepts introduced in a college biology course. Supports the hypothesis that intellectual development…

Examines the influence of standards-based teaching practices on the achievement of urban, African-American, middle school science students. Indicates that teachers who frequently used standards-based teaching practices positively influenced students' achievement and attitudes. Supports the efficacy of high-quality professional development to…

Discusses the influence of a reflective, explicit, activity-based approach to nature of science (NOS) instruction used in an elementary science methods course on preservice teachers' views of some aspects of the nature of science. Finds that participants made substantial gains in their views of some of the target NOS aspects. Advocates a…

Examines changes in the science content representations of two prospective elementary teachers during their first year in an experimental teacher preparation program. Finds that opportunities to engage in cycles of instruction guided by structured considerations for content representation contributed to improvements in the teachers' science…

Examines the growth in students' understanding about the nature of astronomy in a one-semester college course. Discusses how students respond to instruction with regard to the extent to which they demand and examine evidence used for justifying claims, integrate scientific and religious views, and distinguish between scientific and nonscientific…
