The investigator presents a descriptive survey related to the use of behavioral objectives in audiotutorial programs for the teaching of Introductory College Geology in nine colleges and universities in the United States. If goals and objectives were not given serious attention by the developers of predesigned instruction, reasons for omission…

Investigated was the assumption that college students are fully capable, by the time they enter college, of operating at the level of formal thought. The subjects selected for this study were students in chemistry and physics courses at a state university and an inner-city community college. Each student was tested with a Piegetian task to…

This study describes a workshop designed to improve elementary science instruction by encouraging teachers to discard the "spectator" mode of participation and become involved in a program designed to be compatible to the objectives and philosophy of the Science Curriculum Improvement Study (SCIS). A random sample of 224 teachers (the…

This paper describes an approach to using science activities as a means to teach English in the English-as-a-Second-Language (ESL) classroom. It is based on the author's work in Preparing Refugees for Elementary Programs (PREP) at the Philippine Refugee Processing Center. Refugee children from Vietnam, Laos, and Cambodia, ages 6 to 12, attend…

The purpose of the study was to determine differences in chemistry resulting from a traditional and an independent technique of teaching. The population included four chemistry classes at Scottsdale Saguaro High School. Intact groups were assigned to experimental or control groups by random processes. The control group was presented the CHEM Study…

The purpose of this study was to determine the effectiveness of doubling the laboratory experiments and time in the laboratory on student achievement, performance on laboratory skills, and attitude toward high school chemistry. One hundred forty-three students were assigned either of two treatments. All students performed the same basic…

This investigation explored the question of how high school chemistry students best learn three-dimensional molecular, ionic, and metallic structures in CHEM Study (Freeman, 1963). The experimenter compared the achievement, attitude, and instructional preferences of 110 randomly selected students taught by two different methods: (1) student…

The purpose of this study was to determine if eighth-grade students in junior high and middle school science classes could order selected science categories on the basis of the attribute interest into rank orders which were consistent and reliable. A sample of eighth-grade science classes from Wisconsin was selected. A set of…

The intent of this study was to assess the content structure of college biology lectures and to determine the extent to which that structure differed in lectures by a given professor and among lectures of different professors. Content structure was based on the amount of contiguity and commonality of verbal elements between pairs of discourse…

The purposes of this study were: (1) to evaluate the effectiveness of audio-tutorial (A-T) instruction and (2) to identify, classify and study differences in problem solving approach using a theoretical framework derived from the ideas of D. P. Ausubel. Seventy of 420 students taking a college introductory non-calculus physics course used A-T…

The ultimate goal of this study was to specify conditions which affect achievement in the chemistry laboratory through an understanding of instructor-student interaction. The Flanders System of Interaction Analysis was used to measure the ratio of indirect to direct teaching (I/D/ Ratio) during pre-lab and post-lab sections of eight two-hour…

The purpose of this study was to compare the performance of students receiving immediate reinforcement and feedback within an autoinstructional system to that of students in the same system but not receiving immediate reinforcement and feedback. Two teachers, randomly selected, and two groups of 24 students, randomly chosen, were the participants.…

An experimental treatment consisting of inquiry laboratory experiences was administered to a group of 41 students enrolled in an introductory college chemistry course. Using a control group of 36 for comparison, students were evaluated to determine attitudinal changes, critical thinking skills, content mastery, laboratory performance skills, and…

Reported is a study of relationships between personal characteristics and achievement in and attitude toward an audio-tutorial (A-T) biology program. A sample of 119 volunteers, participants in a year-long A-T biology program, was included in the study. Data analysis was conducted in three phases: (1) the Attitude Toward the A-T Method…

Investigated were possible relationships between performance in general college chemistry and secondary school preparation in chemistry. The researcher examined achievement in general college chemistry as a possible function of the student's high school science courses, mathematics courses, socioeconomic status, and scores on the ACT tests. Data…
