This study describes the improvement in 20 sixth grades students' reasoning abilities in the context of structured or semi-structured inquiries conducted during an after-school science club. The findings shed light on the improvement in student reasoning and on the specific areas of student difficulties. Overall reasoning skills showed more or…

Engaging students in science learning can be challenging, and incorporating new forms of technology into science has been shown to provide creative learning experiences. However most technology enhanced learning and e-Science experiences to date have been designed and run by researchers. There is significant challenge in moving these experiences…

This book is designed to provide guidance and ideas for science projects to help students learn more about science as they search for answers to specific problems. The 20 topics on electricity in this book suggest many possible problems to solve. Each topic has one detailed experiment followed by a section that provides additional questions about…

For many summers the Radiation Science and Engineering Center at Pennsylvania State University has been the site of a Nuclear Concepts and Technological Issues Institute for secondary school science teachers. As a culminating activity of the institute teachers develop lesson plans, laboratory experiments, demonstrations, or other activities and…

This book contains scaled-down versions of Exploratorium exhibits that teachers can make using common, inexpensive, easily available materials. Each topic begins with a drawing of the original full-sized exhibit on the museum floor, a photograph of the scaled-down version which contains an introduction to the exhibit, a list of materials needed…

Understanding of immunological techniques such as the Enzyme Linked Immuno Sorbent Assay (ELISA) is an important part of instructional units in human health, developmental biology, microbiology, and biotechnology. This paper describes a simple ELISA exercise for undergraduate biology that effectively simulates the technique using a paper model.…

A series of charts lists weekly activities for conducting a hands-on science laboratory in grades K-6. Arranged by grade level, the charts complement chapters in the "Gateways to Science" textbook series (McGraw-Hill, 1979). For each week, a concept to be explored is tagged to a 45-minute activity. This document was selected by the…

Problems in the experimental laboratory in scientific research are discussed and solutions are proposed for the problem of conflicts between the experimental model and reality. As a possible beginning for change, an apparatus is suggested to replace the tachistoscope. (SCC)
