This thesis has explored the procedure utilized in the writing, testing, and revising of a programed text on animal development. First, this study has discussed the need for self-instructional material in the schools of this country. Next, the study has provided evidence which shows the need for programed material on animal development for general biology classes at Ball State University.This study has then described a procedure for organizing and writing the programed material. Following this, the thesis has outlined a methodology for testing the program, treating the data, and revising the program. Finally, the study has included a discussion of the specific revisions in the program based on the test results.Included in the appendix of this thesis is a final draft of the manuscript of the program.

Cotton fiber has been postulated to undergo a process of programmed cell death (PCD) during the maturation phase of development. A parallel may exist between cotton fibers and xylem tracheary elements, which have periods of elongation, secondary cell wall deposition and death. Secondary wall formation and PCD are purported to be coupled events in tracheary elements. In this study, an attempt was made to observe the occurrence and timing of PCD in cotton fibers by TUNEL staining to detect DNA strand breaks, and also to monitor DNA content by PI staining. The staining patterns produced by PI and TUNEL left room for interpretation. TUNEL-positive and PI-stained areas were observed, but failure to observe nuclei of conventional appearance in my cytological preparations at any time-point, along with possible nonspecific staining or autofluorescence of cell wall and intracellular components, made it difficult to draw firm conclusions of significance. Thus, additional analyses will be needed to prove or disprove current PCD theories. Nevertheless, the differences in TUNEL and PI signals across fiber development stages indicate that the observed fluorescence patterns are marking discrete developmental phases. The PI signal is dispersed throughout the cell during the elongation phase (5-15 DPA) and appears to condense during secondary cell wall synthesis (25- 40 DPA). TUNEL-positive signal may be observed as early as 25 DPA, but the signal is not widespread until 45 DPA. At 50 DPA and beyond, PI staining is reduced. Visually detectable DNA can be extracted from cotton fiber nuclei between 5 and 40 DPA, although a laddering pattern was not visible at any time-point. The results, although inconclusive, point to the possibility that PCD may be a process leading to maturation in the cotton fiber, succeeding completion of secondary cell wall synthesis.

This study was undertaken to determine if a programmed machine is superior to a programmed text in teaching fluidic concepts to Industrial Education majors. An eighty frame linear program was produced in both text and thirty-five millimeter slide forms. A machine was constructed which displayed the slide, evaluated the response by the subject, and provided instantaneous feedback by cycling forward or backward one slide within the series.A group of randomly selected subjects was exposed to each of these programs and their learning measured by a criterion instrument of suitable reliability. A third group experienced only the criterion instrument.Statistical analysis revealed the performance of both programs to be significantly superior to no treatment. A comparison of the two experimental groups indicated the advantage of the machine group to be non-significant at an acceptable level of confidence.

This creative project is an attempt towards developing a self teaching device in the area of linear measurements, which gives an immediate response. The primary purpose of the project is that of facilitating learning in basic linear measurements. This was accomplished through the use and construction of a teaching device that will operate in much the same manner as a teaching machine or a programmed text.Three linear measurement device created is an electrically operated punchboard type device which the student operates by himself. An entire program of instruction cards and sequential key coded plastic panels are developed for a fractional measurements learning situation.
