About this Evaluation Report
Content Analysis
Instructional Analysis

Glencoe Physical Science is one of three components of the Glencoe science program, which distributes physical, Earth, and life science topics across the middle grades.

The program has been evaluated in terms of how well its content matches each of three topic-specific sets of key science ideas, and how well it provides effective instructional material in terms of a set of universal criteria for the teaching of science ideas. This report on the Glencoe program assesses the program’s physical science component.

The physical science idea set focuses on the particulate nature of matter and the kinetic molecular theory. In Glencoe Physical Science, the material relating to these key ideas is to be found in five chapters. Chapter 5: Energy introduces the idea that matter is made of particles and links it to the concept of thermal energy. Chapter 6: Using Thermal Energy explains transfer of heat in terms of moving particles. Chapter 8: Solids, Liquids, and Gases describes and explains physical characteristics of states of matter, changes of state, and behavior of gases in terms of the kinetic molecular theory. Chapter 9: Classification of Matter presents atoms as the units that make up all matter in the context of defining elements and compounds. Chapter 10: Atomic Structure and the Periodic Table notes that Greek thinkers defined atoms as the smallest part of matter.

The other two sections of this report—the Content Analysis and the Instructional Analysis—summarize the results of the evaluation of Glencoe Physical Science’s content and instructional efficacy.

In both sections, within-the-text page references to the evaluated materials have been clarified by the use of letter suffixes: “s” denotes the student text (as in “p. 16s”), and “t” denotes the Teacher Wraparound Edition (as in “p. 16t”); where “T” appears as part of a page reference (as in “p. 13T”), it denotes the Teacher’s Guide within the Teacher Wraparound Edition.

The reference works cited in this report are given as complete citations in the References list, along with those cited in other reports in this document. The References list can be accessed by clicking on the link at the beginning of each content and instructional analysis. To view a specific research reference while reading the content and instructional analyses, simply click on the in-text citation.

The key science ideas and the instructional analysis categories are presented and discussed under Project 2061 Analysis Procedure on the main menu.
