Reports on a study of student understanding of the wave nature of matter in the context of the pattern produced by the diffraction and interference of particles. Errors made by students after standard instruction indicates the presence of similar conceptual and reasoning difficulties at three different educational levels. (Contains over 20…

Illustrates some of the possible uses of the CCD camera in science teaching. Starts with the introduction of Flexcam which is a type of CCD camera used primarily by biology teachers and uses Flexcam to demonstrate observations and scientific skills in connection with the TV monitor. (Author/YDS)

Introduces the Technology-Based Learning in School Science (tBLISS) project which investigates the feasibility of technology-based science curriculum implementation and examines the science process skills of students. Water is the major theme of the curriculum. (YDS)

Makes a case for why teaching about 'ideas and evidence' requires more attention to the teaching of argument in school science. Outlines various practical methods and strategies of local teachers through which this might be achieved. Explores difficulties and obstacles. (Contains 19 references.) (Author/ASK)

Discusses the results of a study that explored first year university students' ideas about measurement in the physics laboratory. Uses the 'point' and 'set' paradigms as a model to analyze responses to written probes. (Contains 21 references.) (DDR)

The purpose of this paper was to investigate students' views on models and modelling in science as well as the role that models play in learning, using a theoretical framework of models in learning. Students' views on models in science were investigated using a pencil-and-paper questionnaire given to 275 students from Grade 8 (13 years old) to…

As one of the authors was warning the fifth-grade class about protecting clothes from spills in the lab, one student commented that his pants wouldn't stain because they were covered with some "nano stuff." The class tossed water on the pants and watched it bead up and roll off "like magic." The class's interest was piqued, and the questions…

Learning to write well is a long process that comes through teacher modeling, instruction, practice, and feedback. Luckily, the writing process can be used to improve science learning, too. There is perhaps no better place than a science journal for students to develop informational writing skills. Daily journal prompts are one way to encourage…

In the spirit of the National Science Education Standards (NRC 1996), many teachers attempt to have their students experience science in a constructivist, inquiry-oriented manner. The egg bungee jump activity will certainly support that mode of teaching, and has the added benefit of providing a concrete context within which students can explore…

For Mr. Kim's fifth-grade students, recess is not just for playing and getting exercise! One spring, he observed a small group of his students near their class bluebird box, examining various bird feathers found on the ground. Building on students' natural curiosity, Mr. Kim purchased some feathers for further exploration in the classroom. He was…

Capillary electrophoresis is gradually working its way into the undergraduate laboratory curriculum. Typically, experiments utilizing this newer technology have been introduced into analytical or instrumental courses. The authors of this article have introduced an experiment into the introductory laboratory that utilizes capillary electrophoresis…

This article provides suggestions on ways in which science process skills can be taught in a meaningful context through children's literature. It is hoped that the following examples of how process skills can be taught using children's books will provide a starting point from which primary teachers can create additional examples. Many…

Each of these outstanding selections defies the traditional image of a child "curling up with a good book." Yes, they can be a source of great personal reading, encouraging students of all ages to stretch their skills and their imagination as they interact with the printed page. But these journeys of the scientific imagination seldom end with the…

This article describes the outgrowth of a recently held invitational conference, supported by the National Science Foundation, to define, describe, and examine existing models for the use of elementary science specialists. The authors explore the educational, policy, and financial issues that affect the use of science specialists as well as offer…

This article describes a two-semester general chemistry laboratory teaching approach to assist students in gaining experience with science-process skills. The ultimate goal is successful completion of a second-semester service-learning project requiring use of their newly developed science-process skills. The project entails creating an…
