Many words which have been treated in the denotative sense are actually connotative in nature. That is to say that citing a definition or stating a fact should not be a learning goal. Rather, a "conceptualization" should be what teachers are striving for. A series of activities dealing with density have been provided for demonstrations or…

Agriculture and the rural economic bases in mining, fisheries, forestry, and natural resource extraction are experiencing major social and economic changes. The farm and rural crises of the 1980s are not short-term aberrations, but symptoms of long-term trends that were partially hidden by the relatively good times for agriculture and rural areas…

This booklet provides background information and five experiments which focus on how energy is lost. Section I contains two experiments to help students discover how energy is lost in their homes. These experiments involve determining a home's location and the weather forces acting on it and completing a home energy audit. Section II contains two…

Listed in this science syllabus are concepts and understandings in eight major areas: (1) forces, motion, and work; (2) introduction to energy; (3) mechanical energy and machines; (4) sound energy; (5) electromagnetic energy and light energy; (6) heat energy; (7) electric and magnetic energy; and (8) nuclear energy. The booklet also includes…

A cultural divide exists in the classroom, with each participant (teacher and student) having rarely-coinciding objectives for a session. In this paper, the authors wish to reflect on the teaching and learning of science as a process of creating understanding from both sides of this cultural divide. Gary, the second author, describes the…

Research in the field of "information-seeking behavior of scientists and engineers" has been done on the behavior and preferences of researchers with respect to technical literature, computer-based information systems, and other scientific and technical information (STI) systems and services. The objectives of this project are: (1) to…

A random half of the instructors of an introductory course in computer programming were given feedback from students' evaluations of instructional effectiveness conducted at the middle of the term. The impact of the feedback was assessed against three criteria: (1) change in students' evaluations between mid-quarter and end-of-quarter; (2)…

The goal of this project was to find ways of enhancing the efficiency of searching machine readable data bases. Ways are sought to transfer to the computer some of the tasks that are normally performed by the user, i.e., to further automate information retrieval. Four experiments were conducted to test the feasibility of a sequential processing…

Recognizing the problems and challenges associated with teaching general level or non-academic science courses in junior high school, a series of manuals was written to assist teachers in developing programs which focus on issues related to science and society. In the first in the series, how to make water fit to drink is investigated. Eight…

Presented are 10 science energy education units designed to help students learn how to turn science questions and problems about energy into experiments. Each unit focuses on subject-matter knowledge and on the logic and strategy of scientific problem solving. These teacher-oriented materials include an overview of each unit, background…

SPEECH IMPROVEMENT TECHNIQUES FOR MENTAL RETARDATES WERE EXAMINED USING COMMUNICATION-CENTERED SPEECH THERAPY TO ENHANCE ARTICULATION AND GENERAL ORAL PRODUCTION AND TO IMPROVE SUCH RELATIONSHIP ATTRIBUTES AS COMMUNICATIVE INITIATIVE AND EASE IN SOCIAL SITUATIONS. A BATTERY OF TEST DEVICES WAS DEVELOPED, INCLUDING THE SAN FRANCISCO INVENTORY OF…

RECENT FEDERAL REPORTS ON NEGRO ACHIEVEMENT IN BIRACIAL SCHOOLS SUGGEST THAT ON THE AVERAGE NEGROES AND WHITES ACHIEVE BEST IN WHITE-MAJORITY SCHOOLS, AND THAT THE RACIAL CONTACT IS AN IMPORTANT VARIABLE IN THIS EFFECT. PSYCHOLOGICAL RESEARCH IN BIRACIAL LEARNING SETTINGS POINTS TO THREE FACTORS WHICH MAY HAVE A DETRIMENTAL EFFECT ON NEGRO…

AN EXPERIMENTAL MULTILEVEL INSTRUCTIONAL PROCEDURE FOR TEACHING HISTORY AS AN INQUIRY PROCESS WAS TESTED ON EIGHT SEVENTH-GRADE CLASSES TO INVESTIGATE CHANGES IN TEACHING BEHAVIOR AND PUPIL LEARNING OUTCOMES, AS COMPARED WITH CONVENTIONAL TEXTBOOK METHODS. WHILE NO CLEAR EVIDENCE WAS OBTAINED THAT PUPILS PREFERRED TO WORK WITH THE MULTILEVEL…

THE PURPOSE OF THIS STUDY WAS TO SURVEY AND REPORT THE POLICIES AND PRACTICES OF ACCREDITING AGENCIES, ALL STATE DEPARTMENTS OF EDUCATION, AND SELECTED PROFESSIONAL EDUCATIONAL ORGANIZATIONS CONCERNING THEIR POSITION ON EXPERIMENTATION AND INNOVATION BY THE PUBLIC SCHOOLS. BOTH INTERVIEWS AND QUESTIONNAIRES WERE ADMINISTERED TO 22 PROFESSIONAL…

There is some confusion in discriminating basic educational research (which explores the why's and how's of learning) from applied research (which seeks to test the implications of basic research results) because some investigations are conceived without a clear purpose. Thus, it is not uncommon for researchers to suggest implications that…
