To improve the teaching and learning materials for a curriculum it is important to incorporate the findings from educational research. In light of this, we present creative exercises and experiments to elicit, confront and resolve misconceptions in geometrical optics. Since ray diagrams can be both the cause and the solution for many…

Research globally has shown that many children lose interest in science towards the end of primary school and throughout the post-primary phase. This article explores children's experience and views in Irish schools that have adopted innovative practices that aim to empower, excite and inspire children in science. One of these focuses on explicit…

By the 1970s a fundamental shift had taken place in German science education. This was a shift away from the learning of more-or-less isolated facts and facets in Biology, Chemistry, and Physics towards a restructuring of science teaching along the general principles of the respective science domains. The changes included also the addition of…

Hands-on, inquiry-based, and relevant to every student's life, "Gourmet Lab" serves up a full menu of activities for science teachers of grades 6-12. This collection of 15 hands-on experiments--each of which includes a full set of both student and teacher pages--challenges students to take on the role of scientist and chef, as they boil,…

Describes a science activity which allows secondary level students to discover the law of refraction. (SL)

Using examples this article tries to dispel a common misconception that theories "mature" into laws by constant testing and confirmation. (GA)

Discusses a laboratory exercise simulating the paths of light rays through spherical water drops by applying principles of ray optics and geometry. Describes four parts: determining the output angles, computer simulation, explorations, model testing, and solutions. Provides a computer program and some diagrams. (YP)

Answers the question about the crown effect of a liquid drop. Describes the concepts of surface tension, irregularities, and pinch effect. (YP)

Finds that interpretation of Galileo's only known experimental manuscript produces some interesting questions that offer pedagogical applications. Promotes classroom "research games" consisting of reconstructed experiments with Galileo's inclined plane and with other instruments to allow further speculation. (Author/WRM)

Presented is a review of three methods for evaluating the effects of laboratory work in high school science instruction. The report focuses specifically on evaluating student performance, what aspects are to be evaluated, and how to evaluate. A table is given of some of the limitations and benefits of each of the assessment procedures. The authors…

Describes a physics demonstration in which two-liter plastic bottles can be used to show how force relates to pressure and area. Identical drinking straws are launched out of similar plastic bottles with different-sized openings. This demonstration proves qualitatively that pressure is inversely proportional to the area exposed to an object when a…

Describes the development of an innovative, multimedia, interactive CD-ROM aimed at helping teachers tackle the problem that students have with evaluating science laboratory work. (Author/WRM)

Describes unexpected experiences with student laboratory activities. Makes recommendations for addressing two types of lab disasters: (1) when lab preparations fail prior to the beginning of lab; and (2) when students produce unexpected results with the proper use of materials. (Contains 11 references.) (WRM)

Discusses preliminary research on a new heuristic tool for learning from laboratory activities in secondary science. Finds that use of the science writing heuristic facilitated students in generating meaning from data; making connections among procedures, data, evidence, and claims; and engaging in metacognition. (Contains 29 references.)…
