The purposes of this study were to develop social biology units emphasizing the social problems of pollution, drugs, and disease; and to assess the level of interest and acquired attitudes among students participating in the field test of the units. The three units written were: Pollution: A Threat to Your Community; Drugs, Life or Death; and…

This study was designed to compare the effectiveness of inductive and deductive programmed instruction for high school students. The sample was formed from high school chemistry students in three schools. In two of the schools, the students worked on the programmed materials on four consecutive days and were tested on the fifth day. At the third…

This study is an empirical investigation of Ausubel's paradigm of meaningful learning, applied specifically to the learning of high school physics students. In the first phase of the study path analysis and multiple regression techniques were used to describe the Ausubelian learning variables: available relevant ideas in learner's cognitive…

This publication, one part of a three-part NSTA series on energy-environment, is a sampling of current energy literature. The references are divided into four separate categories, each directed for a specific audience: readings for teachers, readings for students (grades 8-10); Readings for students (grades 5-9); and readings for students (grades…

This booklet is designed to direct elementary and junior high teachers of science in assessing and comparing their professional goals and practices with those of their colleagues and with current objectives and teaching behaviors recommended by specialists and researchers in science education and curriculum development. Each of 36 statements…

Reported is a study to investigate problems handicapped readers had with the Intermediate Science Curriculum Study (ISCS) test and of a method for adapting the test so that it might be more understandable. Seven questions related to the 1968-1969 ISCS test Probing the Natural World, Volume I were studied. The investigations of these questions was…

This investigation was conducted to determine the validity of the use of Computer Assisted Instruction (CAI) as a tool in formative curriculum evaluation. The instructional materials were selected from 1968 grade seven materials produced by the Intermediate Science Curriculum Study (ISCS). The comparison of student performance within these…

This report describes the creation, funding, promotion, and evaluation of the three resource centers and the instrument repair center of the Del Mod System. Included in the document are descriptions of the three science-mathematics resource centers at the University of Delaware, Delaware State College, and Delaware Technical and Community College.…

This monograph describes the field agent of the Delaware Del Mod System. The following sections are included in the report: (1) The Duties and Activities of the Del Mod System Field Agents; (2) The Field Agents' Mode of Operation; (3) The Conduct of Projects; (4) The Hiring and Training of Del Mod Field Agents; (5) The Administration of Del Mod…

The organization of three subschools at Grover Cleveland High School, Ridgewook, N. Y., is designed to meet the special needs and desires of the students. The first alternative school is for students with records of excessive absences; the second is for above average students interested in majoring in science; and the third is for average or below…

This article is an introduction to "Oceanaids." An Oceanaid is a list of ideas for the teacher on how he or she may incorporate interdisciplinary topics from the marine sciences into everyday classes, regardless of the subject matter or pupil age. A typical Oceanaid, Marine Mammals, is included. (Author/BB)

Describes a laboratory exercise designed to introduce students to the Pourbaix diagram for cobalt. Discusses the use of a Pourbaix diagram as a potential-pH plot which displays some of the most thermodynamically stable species for a given element. Outlines a laboratory demonstration and a student investigation. (TW)

Outlines five simple and inexpensive methods for students to use in identifying unknown substances. Provides a table of general solubility data for ions, a suggested list of unknown substances that can be tested using the methods described, and some prelaboratory information. (TW)

Uses capillarity as an example of a problem in physics which has been explained mathematically in two different ways. Argues that only one explanation is indeed valid and demonstrates this opinion through experimentation and discussions. Proposes that mathematics should be used in physics as a tool to predict, not to explain. (TW)

Describes the reasoning patterns characteristic of the abstract thinking required for higher levels of school science. Discusses control and exclusion of variables, ratio and proportion, conservation involving models, compensation and equilibrium, correlation, probability, combinatorial thinking, coordination of frames of reference, and…
