This article describes a unit of work that was designed for a Year 9 class of mixed ability and which involved the definition and measurement of angles, as well as the practical application of angle properties--such as complimentary angles and the relationships in a transversal. The unit considered the numeracy skills required to interpret a…

In this research we present the use of some technologies in problem solving activities (at different secondary school grades), aimed at finding a model for a geometric configuration, and representing this model in various ways: through a construction, through a Cartesian graph, etc. The task is part of a teaching experiment, in which students used…

Describes an experimental approach to determining the speed of light in water using some simple observations and Fermat's principle. Enables students to integrate mathematical techniques and encourages mathematical exploration in which the students have control over what mathematics and technology to use and when to use them. Presents extensions…

Because continuous learning and knowledge generation are core competencies in our ability to resolve the problems facing us as a world community, we must reject the efficiency model and embrace the emerging model of learning. Current schooling structures are counter to new brain/mind learning precepts. Learner-as-pioneer requires individuals to…

A technique for studying various properties of soap bubbles subjected to deformation, accompanied by some representative experiments to illustrate the versatility of the method, is presented. The measurement of the change of force that occurs when a bubble is stretched is calculated. (KR)

Gives several sample experiment problems for electricity and magnetism. To solve an experiment problem, students have to do one or more of the following: clarify a poorly defined problem, divide a problem into parts, access the appropriate concept needed to solve each problem part, decide whether approximations are appropriate, design an…

The rapid growth of science and technology has a tremendous impact upon how an individual functions in today's society. This experiment-oriented course encourages the student to investigate home economics subject matter from a scientific viewpoint. Using the scientific method to solve problems and make decisions, the student conducts laboratory…
