The purpose of this study was to investigate (a) what effect the use of interactive computer-based simulations (ICBSs), the use of laboratory inquiry-based experiments (LIBEs), and the use of combinations of an ICBS and a LIBE, in a conceptually oriented physics course, have on science teachers' beliefs about and attitudes toward the use of these…

The National Aeronautics and Space Administration's unmanned mission to Mars has inspired students throughout the United States and abroad to take part in a variety of science lessons and projects. These particular students get to sit down the hall from the Mars Exploration Rover navigational team and work on projects directly related to the…

Many varieties of data acquisition systems are now available for science classrooms. Most systems consist of a range of sensors--typically called probeware--connected to an interface unit usually described as a datalogger due to its capacity to record data from these sensors. Although some systems operate independently, most units connect to a…

Probeware is increasingly being implemented in science classrooms because it is less expensive than it used to be and improvements in hardware and software have made it more accessible to students and teachers. Many probes or sensors can now simply be connected to a computer, calculator, or other handheld device, and will immediately begin to…

Most high school chemistry labs contain detailed procedures on how to perform experiments, collect data, and analyze findings. These step-by-step instructions often eliminate opportunities for inquiry, higher levels of thinking, and the sense of accomplishment students find through independent discovery. For these reasons, two years ago the author…

White and group used a two question, open-ended tests to separately evaluate students' learning of specific biochemical concepts in the general biology lecture and laboratory, in the first performance assessment of molecular visualization in teaching biochemistry. Two studies were devoted to protein structure using globins followed by one…

We report on an evaluation of the effectiveness of Project ARIES, an astronomy-based physical science curriculum for upper elementary and middle school children. ARIES students use innovative, simple, and affordable apparatus to carry out a wide range of indoor and outdoor hands-on, discovery-based activities. Student journals and comprehensive…

To confront some of the challenges faced by teachers beginning to implement Standards-based inquiry activities in their middle school classrooms, learning coordinators and teachers selected an inquiry-based set of courses and created a District Science Curricula Scope and Sequence, which overviewed the major units and showed teachers and parents…

The development of communication skills is a key component in any science program. However, students do not see the connections between writing and science. In particular, students lack the enthusiasm when the time comes to write lab reports. Students say that they do not see why they should have to write dry, boring lab reports following an…

At many colleges and universities undergraduates pursuing nonscience majors complete introductory science courses which are structured to provide a broad overview of the field. Commonly such courses include large lecture sections which meet twice a week, and small lab sections that are held once a week. A survey was developed to evaluate the…

Many have become aware of the need to assess both teachers' and students' perceptions of the learning environment. This study involved 1,592 tenth grade students and their teachers (n=56) in a study that investigated four aims: (1) to cross validate a slightly modified version of the actual and preferred versions of the Science Laboratory…

This guide provides an overview of waste generating processes and operations that occur in educational or research institutions and presents options for minimizing waste generation through source reduction and recycling. A broad spectrum of waste chemicals in laboratories, art studios, print shops, maintenance, and other operations can be…

This monograph is intended to guide teachers of water resources, technicians and university students in establishing physical facilities which can introduce learners to methods, techniques, and instruments used in water resources management and assessment. It is not intended to serve as an exhaustive list of equipment and their descriptions or as…

Laboratory and professional training activities among instructional units at the Universite de Montreal were evaluated with respect to the prominence of such activities in degree programs, the amount of work required of students, the involvement of the various teaching and supervisory personnel, and the costs. The organization of laboratory and…

This document provides teachers with sources of useful information and new ideas about the high school chemistry laboratory program. Chapters included are: (1) "Introduction" describing the philosophy and specific objectives of this project; (2) "Importance of Laboratory Work"; (3) "Chemistry Lab Outline" listing…
