Describes a three-dimensional computer modeling system for biological molecules which is suitable for sixth-form teaching. Consists of the modeling program "RasMol" together with structure files of proteins, DNA, and small biological molecules. Describes how the whole system can be downloaded from various sites on the Internet.…

Investigates how microcomputer-based laboratory (MBL) activities specifically designed to be consistent with a constructivist theory of learning support or constrain student construction of understanding. Analysis of students' discourse and actions reveal that students invented numerous techniques for manipulating data in the service of their…

Describes a novel method for inducing and measuring cosmic ray showers using a low-cost, microcomputer-based laboratory system. Uses low counting-rate radiation monitors in the reproduction of Bruno Rossi's classic experiment. (Contains 16 references.) (Author/YDS)

ExCELS is a program that supports teachers interested in the use of computer interfacing at the secondary school level. This paper describes an ExCEL-based course developed for science education majors, presents an overview of interface apparatus and how it is used in schools, and gives examples of experiments performed. (LZ)

Reports on the implementation of a relatively low-cost, versatile, and intuitive system to teach basic mechanics based on the use of a Charge-Coupled Device (CCD) camera and inexpensive image-processing and analysis software. Discusses strengths and limitations of CCD imaging technologies. (JRH)

Presents the history and background for the use of computers in medical education at the Norris Medical School at the University of Southern California. Describes the current computer facilities and how computer-based learning is incorporated into the curriculum. (PR)

Provides an overview of a Vygotskian perspective for learning from hypermedia. Utilizes a Microsoft Dinosaurs teaching-learning episode to pose questions concerning the use of hypermedia for learning of mathematics and science. (Author/MKR)

Molecular modeling by computer is used to display stereochemistry, molecular orbitals, structure of transition states, and progress of reactions. Describes new ideas for teaching 1H NMR spectroscopy using computer modeling. (Contains 12 references.) (ASK)

Presents five technology-based activities to teach elementary students about the human body, including: creating a heartbeat graph; charting the benefits of exercise; playing a "sense"ational card game; reading online stories from three children living with various conditions or illnesses; and examining diagrams of the human body that have been…

This paper describes the use of interactive, Physlet[R]-based curricular material designed to help students learn concepts of thermodynamics with a particular focus on the use of kinetic theory models. These exercises help students visualize ideal gas particle dynamics and engine cycles, make concrete connections between mechanics and…

Selections of liquid aldehydes and ketones are proposed for students to determine what property is the best predictor of the color (yellow to red) of their 2,4-dinitrophenylhydrazone derivative. Students may use a computer (spreadsheet or word processor) to analyze results. (Contains 1 table and 3 notes.)

Clickers are electronic response devices with which a student can remotely submit responses to questions or problems posed by a teacher. The problems are typically true-false or multiple-choice questions, but can also include numerical problems. Clicker devices are particularly popular in large-enrollment introductory science, technology,…

The need for effective teachers is growing while national and state standards are putting ever-increasing demands on teachers and raising expectations for student achievement. Low science and mathematics standardized test scores, particularly in the middle grades, reflect unprepared adolescents, perhaps because of ineffective teaching strategies…

Children need new skills if they are to become part of the solution to challenges such as climate change rather than part of the problem. So states the UK's National Framework for Sustainable Schools. Skills include expressing points of view, weighing up evidence, cooperating, thinking critically, tackling real problems, participating in…
