Conformational Analogs of Some Phytoactive Compounds

Description: In an effort to determine if there is a specific conformational structure which is most effective at the appropriate active physiological site, the synthesis of a group of sterically restricted analogs was undertaken. A portion of the polymethylene carbon skeleton of glutaric acid was replaced by selected aromatic carbons in benzenedicarboxylic acids to produce a series of ridged conformers, and the relative plant growth regulating properties of these derivatives were determined.

A Critical Evaluation of Selected Public Relations Functions of the Dallas Police Department Public Information Office

Description: The problem of this study was to determine how well the public information office of the Dallas Police Department performed in three public relations areas: staff consultation, employee communication, and press relations. Interviews were conducted with the command staff of the Dallas Police Department and with nine mass media representatives who had regular contact with both the police department and the public information office. Their answers were compared with public relations principles taken from literature in both the general public relations and the police public relations fields to see if the public information office was succeeding or failing in performing its staff-consultation, employee-communication, and press-relations functions.

The Development and Validation of a Computer-Aided Instructional Program in Mathematics for Business and Economics Majors

Description: The problem with which this study is concerned is that of comparing the results of teaching community college students enrolled in a transferable mathematics sequence for business and economics majors by a computer-aided instructional program and by the traditional lecture method. In order to effectively resolve this problem, an A Programming Language System 360 (APL/360)-aided instructional program was developed and an experimental study was conducted. The APL/360-aided instructional program consisted of three sets of materials.: a manuscript on APL/360, a list of APL programs defining operators relevant to a computer-aided study of calculus, and a collection of problems based on these programs and calculus concepts. The subjects for the experiment were forty-four students enrolled in three sections of Mathematics 112 at Mountain View College of the Dallas County Community College District. The control group, students taught by the traditional lecture method, consisted of twenty-one students. The experimental group, students taught by the APL/360-aided instructional program, consisted of twenty-three students. The same instructor taught all students. The essential difference in the two teaching methods was the use of the computer as a teaching-learning aid in the computer-aided instructional program. The computer was a course supplement to classroom instruction and aided students in obtaining insight into the nature of mathematical concepts as well as serving as a computational aid.

Development of a System for Reporting Disciplinary Problems by Utilizing Data Processing

Description: The problem of this study was to develop and prepare a data processing system that would report, catalog, and file information pertaining to discipline of students referred to the principal. The purposes of the study were to develop a systematic approach to the reporting of disciplinary incidents, to develop a system of reports that could show what actions were being taken in specified areas and that could provide a cross reference of this information with other data, and to provide a system whereby information concerning disciplinary problems and actions taken could be compiled for a future longitudinal study.

The Effect of Analogy-Structured Teaching on Student Achievement in Ninth-Grade Physical Science

Description: The purpose of this study is to investigate the effects of using verbal analogies in teaching ninth-grade physical science. The experiment is designed to determine if teaching by analogies is more effective than conventional methods of teaching, and to ascertain the effect of analogies on achievement for different ability levels in different subject areas of physical science.

The Effect of Didatic-Intellectual Training Versus Relationship-Oriented Training Upon Counseling Behavior

Description: This study compares the effects of a relationship-oriented practicum to those of a mixed, didactic-intellectual, relationship-oriented practicum upon counseling behavior and personality. These effects are determined by ratings of audiotape recordings as well as by a personality inventory. The audiotape ratings measure changes in counseling behavior, while the personality inventory measures personality changes.

Effectiveness of a Performance Contracting Program in Reading and Mathematics Relative to Educationally Deprived Secondary School Students

Description: This study has two purposes. The first is to compare the academic skills achievement in reading and mathematics of students participating in a performance contracting program with the academic skills achievement of students not participating in the performance-based program. The second is to determine whether those students participating in the performance contracting program show a significantly different level of achievement (higher or lower) than the control group approximately four months after the conclusion of the program.
