Difficulties in implementing the EXCHECK/Voice Oriented Curriculum Author Language (VOCAL) System, a general program designed for university-level computer-assisted instruction in mathematics and science written in the VOCAL language, are presented in terms of informal mathematical procedures, audio and prosodic features, and a schedule of…

This final report on field testing of minicourses in undergraduate biology lists the objectives, procedures, applications, and conclusions of the project in which twelve schools utilizing minicourses, developed at Purdue University, were sampled. Data were collected and analyzed on student achievement, student attitude changes, and student…

Presented are environmental education lessons adapted for use in the second-grade classes of Pinellas County, Florida. Many examples are drawn from local situations. Six conceptual schemes provide the guide's organizational framework: interrelationships, heredity and environment, change, effects of population growth, finite resources, and…

This article presents a rationale for incorporating reading activities with science. It emphasizes that science investigations can provide a background for, and an interest in, reading among students. Three approaches for using science as a vehicle for reading are given: (1) the unit approach; (2) the tradebook, activity card approach; and (3) the…

This publication is a laboratory study guide designed for mechanical engineering students. All of the experiments (with the exception of experiment No. 1) contained in the Mechanical Engineering Laboratory Manual have been included in this guide. Brief theoretical backgrounds, examples and their solutions, charts, graphs, illustrations, and…

This paper is divided into two sections. The first section presents a discussion of the characteristics of the disadvantaged child and the ways in which the philosophy and approach of the Science Curriculum Improvement Study (SCIS) meets his/her needs. The second half is devoted to the descriptive reports from teachers and administrators in whose…

This report presents the results of an investigation of the Science Curriculum Improvement Study (SCIS) program and the effects of the Materials Objects unit on first-grade students and teachers. The contents of the report include purposes and limitations of the study, discussion of the instruments, observers, reliability of the Q sort, the…

THIS IS AN OUTLINE OF PROCEDURES FOLLOWED IN DEVELOPING EXHIBITS SUITABLE AS AUTOINSTRUCTIONAL DEVICES AND AS DEMONSTRATION DEVICES FOR EDUCATIONAL TELEVISION PROGRAMS. THE 27 TEACHING EXHIBITS WERE DESIGNED TO HELP STUDENTS UNDERSTAND CONCEPTS AND PERFORM EXPERIMENTS IN PHYSICS, MATHEMATICS, CHEMISTRY, AND BIOLOGY. SOME OF THE EXHIBITS EMPLOYED…

The Secondary and University Education Section of the National Heart and Blood Vessel Research and Demonstration Center (NRDC) at Baylor College of Medicine completed a statewide survey of Texas public secondary school teachers of biology, health education, homemaking, and physical education. The survey ascertained: (1) the status of…

Students in general undergraduate courses in both biology and genetics seem to have great difficulty mastering the basic concepts of Mendelian Genetics and solving even simple problems. In an attempt to correct this situation, students in both courses at Rollins College were introduced to three simulation models of the genetics of the fruit…

Because a science class may contain students with greatly differing reading abilities, the science teacher must not only teach science concepts, but also design an instructional program which meets the needs of students at all reading levels. Such a program might be developed from the following ten ideas. Idea one, guided reading instruction, is a…

This textbook for the college student emphasizes human sexuality as a part of the whole human life experience and contains a balance of biological, psychological, and sociological material. In 16 chapters the following topics are covered: (1) sex and society; (2) historical and cultural perspectives; (3) glandular control of sexual physiology; (4)…

The Institute of Educational Technology of the British Open University evaluated an Open University broadcast course in the chemistry of carbon compounds. Industrial chemistry was a separate but parallel component of the course which was presented by television and radio broadcast. Questionnaires, telephone interviews, and group discussions were…

This study correlates the relationship between varying methods in student evaluation and its effect on student achievement and attrition. The sample studied consisted of 230 students enrolled in three separate semesters of General Biology 11A at Pasadena City College in 1972, 1973, and 1974. The earlier students were given longer exams over three…

In this time of high cost, it is important not to focus on tutorial computer-assisted instruction (CAI) as the only way to use a computer effectively in instruction. Teacher controlled CAI--classroom use of CAI, augmented by a television display--provides one alternative. Non-tutorial classroom demonstrations can be arranged in business education,…
