Reports on a qualitative study in which preservice science teachers (PSTs) enrolled in an advanced methods course participated in a complex, data-rich investigation based on an adapted version of the "Struggle for Survival" curriculum. Uses the Galapagos Finches software and emphasizes giving priority to evidence and constructing…

Introduces an activity in which students learn principles of force and motion, systems, and simple machines by exploring the best position of the dogs on the dashboard. Includes a sample lesson plan written in the five instructional models: (1) engagement; (2) exploration; (3) explanation; (4) elaboration; and (5) evaluation. (KHR)

Provides an overview of the ENVISION program for enhancing middle school science teachers' understanding of environmental science and inquiry. Focuses on the component of the project that engages teachers in conducting their own environmental research. Describes the theoretical basis for the professional development model, linking the model to the…

Examines how preservice teachers' inquiry experiences in a science methods course were influenced by their conceptions of inquiry. Advocates that independent science investigations should part of preservice education and that these experiences should be scaffolded to prompt reflection, specifically about the nature of inquiry, and conceptually…

Describes an activity based on shrinkable thermoplastics in which students explore the percentage of shrinkage of a plastic ruler when it is heated. Includes science content knowledge behind the shrink, national science education standards related to this activity, and a complete guide. (KHR)

Describes an inquiry investigation to enable students to understand water cohesion, surface tension, and heating curves for water. The investigation includes several activities organized in a three-phase learning cycle: (1) exploration; (2) concept invention; and (3) concept application. (DDR)

Presents a checklist of criteria for a standards-based science teacher. Includes a rubric for scoring the checklist. Focuses on the use of inquiry methods and fostering a student-centered learning environment. (DDR)

Describes an ecology curriculum primarily for elementary school students but also adaptable to junior and senior high school classes. Includes investigative and inquiry-based laboratory problems to accompany inquiry-based teaching. Connects the science learning that happens in school to students' own experiences. (SOE)

Describes an interdisciplinary unit for upper elementary students that integrates science, geography, history, and mathematics in the study of spoons. Students determine the volume of each spoon by submerging it in a graduated cylinder of water and measuring the difference in water levels before and after submersion. Shows students that scientific…

Presents an activity that is part of a unit on topography and land masses in the earth science curriculum. Involves students learning about scientific inquiry, comparing a model with what it represents, making and interpreting scale drawings, learning how to use new instruments, and learning about computation and estimation. (JRH)

Describes eight creative inquiry projects for middle-school students, complete with description, time investment, level of difficulty, and student rating. (SR)

Discusses changes in ideas about learning underlying reforms in science education. Highlights experiences with project-based science, which focuses on student-designed inquiry organized by investigations to answer driving questions, including collaboration among learners, new technology, and the creation of authentic artifacts that represent…

Examines student discourse in both small and large contexts. Explores the role of shared inquiry and the nature of consensus-building in students' development of explanations from a collaborative knowledge-building stance. Concludes that two forms of discourse (constructive and generative, dialectic and persuasive) effectively promote progressive…

Describes the development and validation of the Cultural Learning Environment Questionnaire (CLEQ) which assesses eight scales of the culturally sensitive environments of secondary school students. Examines associations between students' perceptions of their culturally sensitive learning environment, their attitudes towards science, and…

Investigates mathematical phenomena with students through a dialog between teacher and students in an inquiry-based mathematics class. (KHR)
