A general theory of how children learn conservation concepts is presented. The acquisition process is described at an abstract level in terms of a rule-sampling system, implying a three-state Markov model with identifiable parameters. Three experiments testing the model's quantitative predictions about conservation learning experiments are…

Data are presented from a Canadian study to show that the cost of laboratory testing is escalating and represents a sizable proportion of hospital costs. Policy interventions will require thorough analysis and will require sophisticated control programs at various levels in the laboratory inquiry system. (Author/MLW)

The objective of this environmental studies unit is to establish a water quality monitoring project for high school students in Alberta while simultaneously providing a unit which meets the objectives of the Biology 20 program (and which may also be used in Biology 10 and 30). Through this project, students assist in the collection,…

Since the major causes of accidents are carelessness and a negative or apathetic attitude towards safety, this guide was developed to facilitate safe, stimulating science laboratory activities by providing both general and specific safety information presented in 12 sections. Subject areas considered in these sections include: 1)…

This study examines the methodologies and costs of establishing educational delivery systems using satellites currently in orbit or planned. It identifies two operational system scenarios and their predicted costs. One system, the Canadian Universities Satellite System (CUSS), is hypothesized to provide the means of transmitting audio and video…

This study examined the writing strategies and text characteristics associated with discovering a scientific principle by writing about an experiment. Sixty-four university students (non-science majors) carried out a physics experiment concerning either buoyancy, or the forces acting on a balance scale, then wrote an informal journal-style note…

Reading youth writing is an avenue for the youth where they can express their opinions and ideas. In this article, the author questions whether practitioners in the field of cultural studies are actually engaged in this particular dialogue. The author has examined several articles written by young people from "Toronto Star." He realized…

TO DETERMINE THE THEORETICAL IMPORT OF TWO KINDS OF LEADERS, SIMPLE AND COMPLEX, A GAME EXPERIMENT SIMULATING INTERNATIONAL NEGOTIATIONS WAS CONDUCTED WITH 20 DYAD NEGOTIATION TEAMS (10 HAVING MEMBERS WITH SIMPLE CONCEPTUAL STRUCTURE AND 10 HAVING MEMBERS WITH COMPLEX CONCEPTUAL STRUCTURE) SELECTED FROM 350 MALE UNDERGRADUATE STUDENTS IN AN…

Recent research demonstrates that many issues related to the structure of natural numbers and the relationship among numbers are not well grasped by students. In this article, we describe a computer-based learning environment called "Number Worlds" that was designed to support the exploration of elementary number theory concepts by…

This article addresses an impasse in debates about online education in university education. One side presents a story of the progressive development of technology as it is applied to the organisation of higher education, leading to pedagogical advances and to the new forms of administration required for the realisation of the technology's full…

Describes two educational programs designed to assist disadvantaged adults in personal development and social adjustment. (SB)

The Don River watershed is located within Canada's most highly urbanized area--metropolitan Toronto. Many residential and commercial uses, including alterations to the river's course with bridges, have had a significant impact on the Don's fauna and flora. Pollutants have degraded the river's water quality, a situation exacerbated by the…

In Ontario, the secondary school science curriculum advocates the use of laboratory activities to reinforce specific scientific concepts and promotes the development of skills in scientific investigation and communication. Students in biology courses are often expected to identify unknown substances using standard tests, but rarely are these tests…

A description of a bilingual education program at the elementary school level spanning five years since its inception is presented in this report. The home-school language switch from English to French made by control and experimental classes involved total immersion in the French-taught curriculum. While focusing on the educational objectives of…
