Presents an activity designed to provide students with opportunities to practice drawing atomic models and discover the logical pairings of whole families on the periodic table. Follows the format of a television game show. (DDR)

Examines the process of action research and how it contributes to the professional development of a first-grade teacher. Explores the research process experienced by the teacher as she examined whether portfolios could be used as an effective means for facilitating and assessing young children's development of science process skills. (Contains 58…

The theory that children's development of strategies-of-science experimentation is a consequence of developments in theory of mind was examined with 72 children in grades one, three, and five. Ability to predict, explain, and affect the reasoning of a doll or cartoon character predicted performance in planning controlled experiments and in…

Presents a mock interview with John Dewey in which the questions are from the present, and the answers are culled from Dewey's writings from 60-100 years ago. Questions relate primarily to the current state of education in science. (WRM)

Describes the development, preparation, and use of a medium that can select against a wide variety of Gram-negative bacteria while still allowing growth and differentiation of a wide range of Gram-positives. (WRM)

Describes a simple, inexpensive modification that changes a brightfield microscope into a darkfield microscope, allowing low-contrast samples to be examined. (WRM)

Describes the construction and use of an inexpensive, portable photometer designed specifically for estimating population sizes in yeast cultures. Suggests activities for use with the photometer. (WRM)

Investigates the practices required for reading graphs in high school textbooks and scientific journals. Discusses the role of high school textbooks in the appropriation of authentic scientific graph-related practices. Finds that scientific journals provide more resources to facilitate graph reading and feature more elaborate descriptions and…

Discusses a study that revealed that science teachers, like their students, are capable of handling positive experimental results but fail to evaluate negative results appropriately. Describes a teaching strategy designed to help teachers develop an understanding of the concept of negative results and to apply the idea to different contexts.…

Defines six types of investigations: (1) classifying and identifying; (2) fair testing; (3) pattern seeking; (4) exploring; (5) investigating models; and (6) making things or developing systems. Challenges the dominance of fair testing in school science investigations. (Author/WRM)

Describes a review of research that addresses the effectiveness of simulations in promoting scientific discovery learning and the problems that learners may encounter when using discovery learning. (WRM)

Identifies middle school and college students' prior ideas about electrostatic induction. Presented students with observational evidence that supported or refuted their own prior ideas in an interview format. Concludes that the Lakatosian rather than the Popperian view is more acceptable in understanding students' responses to conflicting…

A laboratory practical examination was used to compare the investigative skills developed in two different types of general-chemistry laboratory courses. Science and engineering majors (SEM) in the control group used a traditional verification approach (SEM-Ctrl), whereas those in the treatment group learned from an innovative, inquiry-based…

In this article, the author talks about an inquiry-based activity involving yeast, wherein students learned about cell size. The activity allows students to employ math connections and to learn experimental techniques while practicing microscope skills. The activity can be adapted for students at all levels of biology. The author presents details…

The purpose of this study is to investigate how sixth graders develop inquiry skills to construct explanations in an inquiry-based learning environment. We designed a series of inquiry-based learning activities and identified four inquiry skills that are relevant to students' construction of explanation. These skills include skills to identify…
