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…

Argues for using "conflict maps" as a way of enhancing science teaching and learning. The conflict map emphasizes not only the use of discrepant events, but also the resolution of conflict between students' alternative conceptions and the scientific conception. Discusses the conflict map as an instructional aid for teachers or as a…

Proposes a revised learning cycle model termed the Metacognitive Learning Cycle which emphasizes formal opportunities for teachers and students to talk about their science ideas. Analyses two different pedagogical classroom approaches, the Science Curriculum Improvement Study (SCIS) approach and the metacognitive approach, and observes changes in…

Exhibits are a way of self-guided presentation in which visitors use their own knowledge and understanding. Studies a self-guided group visiting an exhibition on dinosaurs which are displayed as robotic models. Finds that the animatronics have a well thought out storyline that increases family and school visitors' understanding of the exhibit…

Argues that cross-morpheme and cross-word syllabification in the WEAVER model of speech production point to the need to deal with flexibility of syllable membership and pose difficulty to a memory-based approach but not to WEAVER. The study reviews empirical support for the form of syllabification in WEAVER and reports an experiment on…

Urges "watering up" the curriculum for adolescents with learning disabilities and identifies principles associated with making knowledge construction more meaningful. Offered are specific instructional techniques for use in inclusive settings, such as focusing on teaching big ideas, promoting elaboration, relating to real-world contexts, and…

Describes a study on the extent to which different children hold animistic notions and the meaning of those notions. Explores the idea of preservice science teachers as researchers. (DDR)

Reports on an effort to improve articulation between science and education at Temple University. Describes the implementation of the cooperative controversy strategy into elementary science methods courses. Contains 26 references. (DDR)

Argues that teachers are challenged to understand how constructivism can serve as a referent for teaching. Discusses one approach that provides opportunities for teachers to practice innovative strategies while engaging in discourse about the process. Contains 25 references. (DDR)

Results of this study suggest that simulation-role-play allows students to demonstrate their understanding, explore their views, and develop deeper understanding of phenomena. The technique was especially beneficial to students who prefer learning kinesthetically. Suggests a strategy for using analogical analysis in simulation-role-play. Contains…

Recommends beginning certain chemistry courses with revision and consolidation of mole calculations. Argues that by choosing examples related to health and safety, mole calculations can be made less academic while raising student awareness of important issues. (DDR)

Reports on a way in which student teachers are given the opportunity to work with partially hearing pupils in the context of environmental education outside the science laboratory. Focuses on student investigation of moss on trees. (DDR)

Recommends the use of beans as an inexpensive, durable, and readily available resource for developing science-process skills in K-8 students. Shares strategies for using beans in graphing, patterning, and classifying. (DDR)

Presents a weeklong earth science module that allows students to explore the relationships between natural and manufactured materials. Relates rocks and minerals in the earth science curriculum to observations students make in their urban and suburban travels. (DDR)

Presents an attempt to improve teaching and learning strategies for science as addressed by prospective teachers. Discovers that prospective teachers share a number of misconceptions with students. Contains 19 references. (DDR)
