The purpose of this study was to determine the concerns of Texas science teachers about the 40 percent laboratory time rule just prior to enforcement and at the end of its first year of implementation. The methodology, results of the first and second years, conclusions, and implications for teaching science are discussed. (KR)

For a two-year period, 32 secondary students gifted in the areas of mathematics and science participated in a curriculum which incorporated higher-level thinking skills and more real-life laboratory experiences into mutually reinforcing mathematics and science lessons. After the program, participants scored higher on mathematics and science…

This collection of lesson plans designed for teachers of 4th- through 12th-grade students utilizes an assortment of teaching strategies for topics related to coal and the coal industry. Activities cover the following topics: coal formation; coal identification; "the geologist's dilemma" (a supply and demand activity); geologic time and…

These units developed for teacher use consist primarily of a collection of typical experiments or research activities developed by staff and participants of a National Defense Education Act Institute. The institute was designed to broaden the viewpoint of 25 industrial arts teachers with regard to some of the newer scientific and/or engineering…

Designed to assist the teacher in introducing a unit on research and experimentation into his/her industrial arts program, this manual provides information for adoption to both classroom instruction and laboratory activities, and a student workbook. The instructor's section includes (1) What is Research? (2) Importance of Research and…
