This publication is the second of a series of seven supplementary investigative materials for use in secondary science classes providing up-to-date research-related investigations. This unit is structured for grade levels 7 through 9. It is concerned with food value of liquified cellulosic agricultural wastes: paper, straw, corn cobs, sawdust and…

The major objective of this study was to determine if an index to indicate the work load of field staff personnel could be developed. The data were collected by the county directors on the basis of information included in the state and federal reports covering the period July 1, 1966 to December 31, 1966. A factor of 450 was used to convert total…

A study was made of the Institute of Lifetime Learning in Washington, D.C.; data were gathered by observation over an 11-month period and through interviews with 19 instructors. An analysis of the findings indicate the following: (1) The institute's philosophy is the provision of non-threatening education for older or retired adults; (2)…

The group discussion literature was examined to determine how fully its principles had incorporated social power principles, and to incorporate relevant power principles into the principles of group discussion. Discussion principles were classified by properties of group members, properties of groups, conditions imposed on groups, interaction…

An exploration of earth's life systems and man's impact on his environment are provided in this boxed set of 70 skill cards for upper elementary and high school students. The core idea of the subject matter is that nothing exists in isolation, with both the man-dominated environment and natural habitats used to illustrate the importance of…

An environmental investigation into how wind behaves is formulated in this unit for grades three through six. The thrust is to get students more aware of the environment in which they live, seeing how their lives are intertwined with all the elements. Specifically, knowing how the wind behaves may lead to a better understanding of how to behave…

The use of calculators in mathematics classes of eight-year-olds was investigated. Results showed that the experimental classes were quicker and more accurate in addition, subtraction, and multiplication than the control classes at the end of the year. (MN)

The National Science Foundation has a long supported the use of "Wisconsin Fast Plants" (rapid cycling "B. rapa") in the teaching of Biology (K-12). I believe that the opportunity is at hand for biologists to significantly extend past efforts made by our colleagues at the K-12 level to higher education. Biology faculty can realize the many…

This paper examines to show how an investigative approach to mathematics teaching can honor its two important dimensions--a thinking and reasoning side to go with the skill development. The paper addresses the question of why a problem solving approach has failed, makes the case for investigations as an overarching organizer, and discusses the…

Fieldwork provides an opportunity to reinforce previous class-based learning and presents students with an opportunity to encounter new ideas and practice new skills. In the K-12 classroom, however, the rhetoric-reality gap between the declared need for fieldwork and doing fieldwork is striking. This project seeks to narrow the gap between…

Discusses the measures needed to promote the study of science in the educational system of Great Britain. (Author/RK)

Although traditional instructional methods and textbooks mitigate against it, investigation can be a viable alternative strategy in the geometry classroom. Many theorems in geometry, such as Euclidean space, lend themselves easily to student experimentation. (Author/SJL)

Presents a guide for conducting investigations of housing discrimination complaints. Outlines interview questions, documentation procedures, procedures for establishing proof of discrimination, and evaluation techniques. (MK)
