Describes how students use paper-strip molecules in hands-on activities to show the synthesis of larger organic molecules from smaller molecules. Focuses initially on condensation molecules involving the functional groups in alcohol and carboxylic acids. (DDR)

Outlines a science curriculum reform effort aimed at enabling students to collect original data concerning an environmental parameter such as water quality on a yearly basis. Students track the overall health of the stream by analyzing both biotic and abiotic factors. (DDR)

Describes a workshop to provide parents, their elementary school children, and elementary teachers with a common science learning environment. It included 45 activities/demonstrations with directions and learning notes. The primary goal was to promote inquiry through involvement and interaction with each other, discovery, discussion, and thinking…

Uses base-year data from a nationally representative database (NELS:88) to identify important explanatory factors for gender differences in science performance. Documents a large advantage for boys on the subtest of physical science and a modest advantage for girls in life science. Concludes that laboratory experiences are beneficial for girls'…

Three principles that guide documentation and assessment of children's early science understanding are: collect a variety of forms of evidence, collect evidence over a period of time, and collect evidence on the understanding of groups of children as well as individuals. Information and insights gained from this process help teachers plan future…

A Research Experience for Undergraduates is an extracurricular opportunity for science and engineering undergraduate students to participate in academic research like graduate students. Describes an effort to incorporate professional ethics into such an experience. The basic premise--integrating explicit discussion of ethical considerations…

Estimates of the costs of including hands-on measures of science skills in a large-scale assessment program were derived from a field trial involving more than 2,000 fifth and sixth graders. Results suggest that complexity makes hands-on assessments more than three times as expensive as open-ended writing assessments. (SLD)

By combining hands-on research and telecommunications, the National Geographic Society's Kids Network enables K-8 students to grapple with basic science and geography concepts, hone communication and research skills, and network with kids around the world. Students focus on real-world problems, work cooperatively, and share results in class…

Explores the interaction between scientific epistemological beliefs and learning orientations in a group of Taiwanese eighth-grade students. Suggests the importance of employing a constructivist philosophy in the classroom. Contains 55 references. (DDR)

Describes a program that introduces students to hands-on, minds-on science and provides an opportunity to work on a project with a scientist-collaborator who uses their data in ongoing research. Introduces students to the rigors of science through the focus on data quality. Contains 21 references. (DDR)

Explains the functions of the Boreal Forest Watch including the scope, level of student involvement, goals, and nature of the data collection. Details student involvement at the forest site. Contains 18 references. (DDR)

Identifies the problems associated with the use of dry laboratories in science education, presents design considerations for the use of such practicals in science education, and presents examples of innovative nontraditional practicals. Contains 23 references. (DDR)

Project ESTEEM (Earth Science Teachers Exploring Exemplary Materials) is designed to improve earth science teaching by providing materials and personnel to reverse the decline in activity-based instruction. During an intense summer program, precollege teachers examine and present activities for earth-science courses. These materials are assembled…

Details a project developed to provide stimulating science classroom environments as incentives to draw talented science majors into teaching. Focuses on the experiences of one student. (DDR)

Presents results from empirical studies of physics learning for different age groups using a situated cognition perspective to construct detailed understandings of how individual learning processes unfold. Contains 35 references. (PVD)
