Reported is a study to compare the achievement of selected 10th-grade biology students on a traditional schedule with selected 10th-grade biology students on a flexible modular schedule. Both groups studied the blue version of the Biological Sciences Curriculum Study (BSCS) materials. Students were paired in the groups on the basis of their scores…

The investigator attempted to show that the use of behaviorally stated objectives in classes of chemistry would result in higher gains in achievement for students in these classes as compared to those in classes where nonbehaviorally stated objectives are used. The multiple linear regression approach to analysis of variance and interaction…

The primary purpose of the investigation was to determine if any attitudinal change toward science occurs in college freshmen during enrollment in selected introductory science courses. Relationships were also sought between: (1) scientific attitude on entering college, (2) enrollment in a course or in no science course, (3) sex of students, and…

This study was conducted in order to assess the difference in concept development and principle learning between high school biology students studying the origin of life from a two-model approach (evolution and creation) and those using the single-model approach of evolution only. The pre-test, post-test control group design using a criterion…

Five randomly selected experimental groups of twenty-four general college chemistry students participated in this study. Four of the five groups received a version of the systems approach treatment, which consisted of group orientation, individualized learning, small group seminars and unit tests. The fifth group was administered the traditional…

This research attempted to identify some of the possible factors related to the downward trend in secondary school physics enrollment in the United States. A pilot study was conducted in one high school to develop a "Science Attitude Inventory" that was then administered to 3,738 college preparatory students in 11 secondary schools in the…

The purposes of this study were to investigate science teachers' attitudinal changes toward an innovative science curriculum and to ascertain what variables were pertinent to these changes. The population consisted of 55 college science teachers assigned to participate in the program beginning with the summer of 1971. The instruments used were:…

The problem of this investigation was to compare the effectiveness of the lecture-discussion method of instruction and the multimedia programmed method in promoting achievement in a noncredit, college level physics course. The three instructors taught 180 freshmen who had failed to achieve a minimum grade of 70 percent on a physics placement…

The purpose of this study was to determine the effects of a teacher in-service education Program of workshops in Elementary Science Study (ESS) and Process Science on (1) the fifth- and sixth-grade teachers who participated in the workshops, and (2) students of teachers who participated in these workshops. A Posttest-Only Control group design was…

The value orientations of 39 chemistry teachers and their 120 students were measured and compared to the theoretical, humanistic, and technological aspects of chemistry. A Chemistry Preference Evaluation Instrument containing alternative statements concerning these three aspects was administered to teachers and students. The reliability…

The purpose of this study was to use an information theoretic memory model to quantitatively investigate classification sorting and recall behaviors of various groups of students. The model provided theorems for the determination of information theoretic measures from which inferences concerning mental processing were made. The basic procedure…

This study was proposed to determine the occurrence, stability, and character of kinetic structure patterns within college physics lessons. Six lectures were randomly chosen from the schedules of each of six cooperating physics professors and a transcription of audio-tape recordings of each lecture was prepared. The flow of discourse was broken…

This study uses as data parts of the material gathered within the Curriculum Diffusion Research Project, a British project which examined the diffusion of new science curricula. The concept and context of curriculum diffusion as a new field of enquiry in Great Britain is discussed, together with the problems associated with its study; special…

This study was undertaken to determine whether hierarchically structured problem situations could be developed and used to identify where individual solutions to problems in elementary physics are interrupted and whether examination of student approaches to problem situations would be useful to physics teaching. A random sample of 26 students…

Methods of instruction involved in an introductory, nontechnical college physics course were studied and compared. Students involved were divided into experimental and control groups respectively, about 50 in each group. The experimental group was instructed by lab method films for six experiments, while the control group was taught traditionally.…
