Past research has identified elements underlying modeling as a core science and engineering practice, as well as dimensions along which students' learn how to use models and how they perceive the nature of modeling. To extend these findings by a perspective on how modeling practice can be used in classrooms, we used design-based research to…

Presents an activity that uses ratio and proportions to create scale model and life-sized drawings of sharks. (ASK)

The use of computational chemistry and the protein data bank (PDB) to understand and predict the chemical and molecular basis involved in the drug-receptor interactions is discussed. A geometrical and chemical overview of the great structural similarity in the substrate and inhibitor is provided.

Describes an integrated approach to teaching a biochemistry laboratory focusing on the relationship between the three-dimensional structure of a macromolecule and its function. RNA is chosen as the model system. Discusses curriculum and student assessment. (AIM)

Describes a model for schools searching for a project to provide focus for instruction across curriculum areas. Argues that schools can foster compassion in students and a desire to take action by selecting a theme that is both engaging and meaningful for students, and providing skills and knowledge from across the curriculum. (CCM)

Two programs are described for teaching earth science and introductory chemistry to secondary students with learning disabilities. Development of the two models involved curriculum revision to engage students in higher order thinking, teaching fewer topics in more depth, and design of materials to provide an integrated, problem-solving basis for…

Discusses advances in hypermedia as an instructional tool for earth system science education as a mechanism for designing user-friendly and structured classroom units. Proposes two models as a foundation for materials development: (1) the Learning Cycle Model; and (2) the Investigation/Experimentation Model. (Author/CCM)

An instructional program was constructed that explored the responses and perceptions of preservice elementary school teachers while finding and using characteristics to construct categories or concepts. The program integrated ideas about teaching thinking skills using computers. HyperCard and videodisk images were used to develop a program so that…

Describes how to place mathematical equations modeling population growth into a spreadsheet that performs calculations quickly and easily. Suggests experiments that can be performed with the spreadsheets. (WRM)

Contrasts spontaneous and reflective knowledge integration instruction delivered using a computer learning environment to enhance understanding of displaced volume. Distinguishes the impact of instruction on students who believed scientific phenomena are governed by principles (cohesive beliefs) versus students who believed that science is a…

Discusses the Technology, Science, Mathematics Integration Project's technological problem-solving method, briefly describes 15 activities and the corresponding technology, science, and mathematics content involved (including 1 detailed example), and proposes a general structure of the activities and research in support of this approach.
