The purpose of this study was to compare two systems of teaching basic college chemistry. Three regression equations were developed for predicting a student's total raw score on the various tests used. The covariates utilized were ACT composite scores and scores on the Watson-Glaser Critical Thinking Appraisal, given as a pre-test. There was no…

This study was designed to identify patterns of selections and performance characteristics displayed by individuals during a concept-attainment task. The relationships between selection patterns and individual characteristics were studied in addition to the effects of changes in task characteristics on selection patterns. The population was 200…

This study was designed and conducted to determine the effectiveness of audio-tutorial minicourses in increasing achievement in the biological sciences at the college freshman level. In 1971, 75 randomly selected students in the experimental group attended regular lecture and laboratory periods in addition to completing 10 minicourses. The 79…

This study investigated three questions: the relationship between the use of stated instructional objectives and achievement in audio-tutorial (A-T) instruction, the relationship of learner personality and achievement under conditions of A-T, as well as determining the power of selected batteries of intellective and personality variables to…

The primary problem was to investigate the relationships between two methods of presenting biological information (lecture-laboratory and audio-tutorial) and students' attitudes toward biology and their terminal achievement. A total of 259 students from Grand Rapids Junior College, Grand Rapids, Michigan, participated while 136 students from…

The study involved the development, implementation and evaluation of laboratory audio-tutorial activities in a college chemistry course. The activities were designed in a self-instructional mode, written as linear programs and taped instructions. A pretest was used in two instances, but all included a posttest. To evaluate the effectiveness of the…

Presented are the procedures, results, and conclusions of a study designed to compare the effectiveness of programed instructional materials with that of conventional materials in university physical science laboratory classes. The subjects were students enrolled in two similar freshmen-level physical science general education courses who were…

This report presents the procedures, results, and conclusions of a study designed to determine if effective provisions for the learning needs of college students can derive greater benefit through methods of team learning than through the lecture method. A sample population of 12 sections (N = 247) of general education physical science was used.…

This instructional and resource guide is designed so that it may be used in the secondary school or in the first two years of college to present a series of units in space science, or to supplement existing science and mathematics courses. The guide consists of six units: (1) measurement, distance, and size in astronomy, (2) atoms, spectra, and…

This volume contains chapters 14-18 for the ACS "Modern Chemical Technology" (ChemTeC) instructional material which is intended to prepare chemical technologists. The content concentrates on the background needed to understand the periodic table; names of inorganic compounds; structures, names and classes of common organic material; chemistry and…

This volume contains chapters 19 to 25 of the ACS "Modern Chemical Technology" (CHemTeC) curriculum material which is intended to prepare chemical technologists. Laboratory techniques and procedures are emphasized. The chapters cover the areas of the techniques of sampling, the techniques of weighing, sample preparation, the measurement of pH,…

This volume is a part of the ACS "Modern Chemical Technology" (ChemTeC) curriculum that is developed for chemical technicians. It is intended as a handbook that will be used throughout the instruction. Safety is stressed in eight of the ten chapters under the headings: safety in the chemical laboratory, personal protective equipment, fire safety…

Provided are biological science laboratory experiments which have been developed and used as a part of an experimental one year undergraduate course in general science for non-science majors. The experiments are directed at the student understanding the balance of chemical and physical processes which must be maintained in order to sustain life,…

Provided are physical science laboratory experiments which have been developed and used as a part of an experimental one year undergraduate course in general science for non-science majors. The experiments cover a limited number of topics representative of the scientific enterprise. Some of the topics are pressure and buoyancy, heat, motion,…

Reported is progress on an experimental curriculum development program by four liberal arts colleges (Clark, Morehouse, Morris Brown and Spelman) directed at the development of a one-year course in general science for non-science majors. The current version of the course and laboratory materials has been tried out with 2,000 students on a…
