Reports on a survey of 72 schools and 51 teachers who have used the Nuffield Combined Science program. The study sought to determine teachers' opinions of material suitability, discovery learning, and to describe physical characteristics of schools using the program. (CP)

This student guide is divided into two sections: "Mice and Men" and "Environmental Balance," and constitutes parts three and four of the first year of the Portland Project, a three-year, integrated high school science curriculum. Part One of the guide deals with topics such as cell, reproduction, embryology, genetics, genetic…

This teaching guide contains part one of the four parts of the first year of the Portland Project, a three-year secondary integrated science curriculum sequence. This part involves the student in a series of activities intended to increase his understanding of his perceptual abilities and their limitations. Organization and classification as parts…

This teacher's guide contains part two of the four-part first year Portland Project, a three-year secondary integrated science curriculum sequence. This part involves the student with unifying principles essential for deeper understanding of the concept of energy. Confidence in the atomic nature of matter is built by relating heat in terms of…

This teacher's guide includes parts three and four of the four-part third year Portland Project, a three-year integrated secondary science curriculum sequence. The underlying intention of the third year is to study energy and its importance to life. Energy-related concepts considered in year one and two, and the concepts related to atomic…

Scientific concepts and processes are best developed in the context of technological problem solving. However, even some of the best secondary science curricula are weak in technology education and visa versa. A goal of technology and science education is to integrate student learning of science and technology. The relationship between science and…

This teacher's guide contains parts three and four of the four-part first year Portland Project, a three-year secondary integrated science curriculum sequence. Part three of the guide deals with topics such as the cell, reproduction, embryology, genetics, genetic diseases, genetics and change, populations, effects of density on populations,…

This teacher's guide includes parts one and two of the four-part third year Portland Project, a three-year integrated secondary science curriculum sequence. The Harvard Project Physics textbook is used for reading assignments for part one. Assignments relate to waves, light, electricity, magnetic fields, Faraday and the electrical age,…

This teacher's guide is for the second year of the Portland Project, a three-year integrated secondary science curriculum sequence. The first of two parts in this volume, "Motion and Energy," begins with the study of motion, going from the quantitative description to a consideration of what causes motion and a discussion of Newton's…

In this set of six booklets on graphing, intermediate grade students learn how to choose which kind of graph to make; make bar graphs, histograms, line graphs, and conversion graphs; and use graphs to compare two sets of data. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended,…

In this set of five booklets on measuring, primary grade students learn how to use a stopwatch, choose the correct tool to measure distance, use a trundle wheel, make a scale drawing, and find the speed of things. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range…

In this set of three booklets on simplifying data, primary grade students learn how to round off data and to find the median and average from sets of data. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range investigations of real problems. In most instances students learn…

In this set of six booklets on simplifying data, intermediate grade students learn how to tell what data show, find the median/mean/mode from sets of data, find different kinds of ranges, and use key numbers to compare two sets of data. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on…

The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range investigations of real problems. Since children often design and build things in USMES, 26 "Design Lab" cards provide information on the safe use and simple maintenance of tools. Each card has a large photograph of…
