This book contains 25 experiments designed to help students understand some of the science used every day. Each experiment includes a list of materials, a series of easy-to-follow steps, an explanation of the scientific principle demonstrated, and additional scientific facts and information. No special or expensive materials are required.…

This paper reports on a theoretical and empirical study into curriculum innovation in secondary education in the Netherlands focusing on mathematics, physics, chemistry, and biology. Curriculum specialists, subject specialists, researchers, policy makers, and teachers were interviewed for the study. Results indicate that mathematics had the most…

From prehistoric times people have been fascinated with color; from cave paintings to the latest computers, color has been a constant companion. Textiles are made more beautiful by the alteration or application of colorants. This teaching resource investigates vat dyes, a colorant class which includes the oldest dyes known as well as important…

This collection of manuals contains the Manitoba Provincial Chemistry Examination for students seeking credit in Senior 4 Chemistry (Chemistry 300) and instructions for its use and grading. The examination is based on the Core Topics of the Senior 4 Chemistry course and accounts for 30% of the student's final grade in the course. The examination…

The Science Assessment Program is part of the overall Manitoba assessment program as recommended by the Joint Committee on Evaluation and approved by the Minster of Education and Training. This report contains a description and analysis, along with conclusions and recommendations of the assessment conducted in Science 100, Biology 200, and Physics…

A concept map is a graph in which the nodes represent concepts, the lines between the nodes represent relations, and the labels on the lines represent the nature of the relations. Concept maps have been used to assess students' knowledge structures, especially in science education. Two concept mapping techniques, constructing a map and filling in…

This study focuses on student concept changes in acids and bases. Variables include field dependent level, personal independence level, interest in science or chemistry, teaching strategy, and student gender. This study of Grade 10 students (N=81) provides information relevant to secondary school chemistry learning, teaching, and concept change.…

This study reports on a high school teacher using emancipatory action research to implement cooperative learning strategies in a chemistry class. Data were collected and analyzed using qualitative methods. The findings of the study indicate: (1) students accept cooperative learning if they feel it can increase their ability to learn content; (2)…

Recent studies in education have indicated that analogies are occasionally included in chemistry textbooks in an attempt to help students' understanding of abstract chemical concepts and sub-microscopic structures. This paper reports on a study in which authors of major textbooks currently used in Australian schools were interviewed to ascertain…

In an effort to investigate the effects of a teaching strategy that helps students to identify concept conflicts through experimentation and guided investigation on students' conceptual changes and learning outcomes, 596 students (393 junior high school, 170 senior high school, and 33 college students) were administered two solution tests…

This publication is designed to direct and support instruction in an occupational spin-off area within vocational cosmetology programs in Oklahoma. This instructor guide contains three units: (1) recognizing arm/hand anatomy and disorders/diseases; (2) preparing for a manicure; and (3) preparing for a pedicure. Each instructional unit includes…

The application of the principles of chemistry both for committing crimes and for tracking down criminals interests audiences of all ages and walks of life. This interest is the reason for the long-standing popularity of fictional works that describe crimes made possible by the criminal's knowledge of chemistry and crimes solved by the sleuth's…

Designed for college-bound students, their parents, and high school teachers, counselors, and administrators in California, this statement sets forth recommendations concerning the skills, attitudes, and qualities that should be imparted by high school science programs and the curriculum and courses to impart them. Prefactory material provides…

Indicates how some branches of chemistry lend themselves to interpretation using a modern mathematical approach. Examples include set theory and the periodic table, matrix algebra and determinants and atomic theory, and symmetry and molecular structure. (GS)
