Epistemic criteria are the standards used to evaluate scientific products (e.g., models, evidence, arguments). In this study, we analyzed epistemic criteria for good models generated by 324 middle-school students. After evaluating a range of scientific models, but before extensive instruction or experience with model-based reasoning practices,…

The purpose of this pragmatic action research study was to explore our re-conceptualization efforts in preparing pre-service teachers to guide the inquiry process with formative assessment and subsequently use the understandings to improve our teacher preparation program. The process was guided by two questions: to what extent did course…

Evaluated the effectiveness of an in-service science program, designed to introduce the Science Curriculum Improvement Study (SCIS) to 35 elementary schools, by measuring teachers' (N=168) use of living materials available from the school district's resource supply center. Findings include no significant increase in material usage by workshop…

Compares results of surveys sent to New Jersey science supervisors in 1978 and 1982 regarding status of secondary science education in their schools. Discusses trends developed during the four-year period, comparing them to such national trends as decrease in instruction time, use of national curricula, and loss of teachers to business/industry.…

Argues that naturalistic research is appropriate for studying science education. Stages of naturalistic research are explained and illustrated with material from NSF-sponsored Case Studies in Science Education. Problems in traditional research methods are presented as justification for inductive models or models based on multiple methods,…

Compares the effectiveness of an Extended Discretion (ED) laboratory approach (exercising independent judgment) to a BSCS Green Version laboratory program. Results from 10 classes taught by five teachers, each teaching one experimental and one control group, favor the ED approach on a number of measures. (Author/JN)

Reports on a study conducted in the Richardson Independent School District (Texas) which was designed to assess the attitudes toward science of students and teachers who have been involved with the Science Curriculum Improvement Study (SCIS) compared to non-SCIS students and teachers. (TW)

Surveyed teachers' perceptions of the SCIS-II elementary science program. Results indicate that grades K-2 teachers rated the program more positively than grades 3-6 teachers. Teachers who rated the program higher perceived fewer barriers to effectively utilizing the program. Teachers rated the program higher for developing social skills and…

Reports a study of the effects of teaching the Elementary School Sciences Program (ESSP) on attitudes towards science of elementary school teachers. (SA)

A battery of tests was administered to three groups of high school students who studied the Israel Biological Sciences Curriculum Study (BSCS) Adaptation Program for several years. Compared with non-BSCS students, the progress of the BSCS students in biological knowledge, inquiry skills, and understanding of science demonstrates the feasibility of…

The study investigates the usefulness of teaching science courses that have a commonality of subject matter and a sequential patterning of operations. Introductory Physical Science (IPS) and CHEM Study courses were compared. The results indicated IPS is a useful background for CHEM Study. (BR)

Questions Whether first-grade student participation in selected experimental activities from the BSCS-ESSP enhances skills in listening as measured by the Cooperative Primary Series Listening Test (CPSLT). (CS)

Achievement scores of Israeli high school students using Biological Sciences Curriculum Study (BSCS) materials were shown to be significantly higher than those for students using another curriculum. (MLH)

Discusses formative evaluation (those evaluation activities carried out while a curriculum is still being developed) and relates this to the development of the Individualized Science (IS) program at the University of Pittsburgh. (PEB)

Summarizes results of the meta-analysis of 105 research studies dealing with effects of new science curricula on student performance. Twenty-seven different new science curricula involving one or more measures of student performance were included in the analysis. Positive performance patterns were found in all new curricula examined. (JN)
