This study was designed to investigate the effectiveness of integrated art-science curricula upon remediation of the misconception held by elementary students that humans are not animals. Quantitative instruments were designed to measure and assess: (1) the existence of the misconception within the test population; (2) the degree to which the misconception existed within grade levels and treatment groups within grade levels; (3) the degree to which any positive level of remediation is achieved; and (4) evaluation of the experimental curricula by participating faculty. Qualitative instruments were applied to measure and assess the reasoning process applied by students for the formation of and any degree of change in the targeted misconception.Two hundred and forty-two students, in grades one, three and five, from a rural elementary school in east central Indiana participated. Enrolllment of students in individual classrooms was accomplished by administration policy of random assignment. Classrooms, by grade level, were randomly assigned to treatment groups by the researcher.Students in control groups at each grade level were instructed according to established curricula of the school. Students in experimental animal science groups were instructed through specifically designed hands-on science activities with the art component being the school's established curriculum. Students in experimental animal art groups were instructed according to specifically designed art activities incorporating observations made during science lessons, with the science component being the school's established curriculum. Students in the both treatment groups received instruction combining the experimental animal science and experimental animal art curricula.Results indicated that students instructed from the experimental curricula demonstrated remediation of the misconception, with students in the both treatment groups of each grade level demonstrating the highest degree of remediation. Students in control groups failed to demonstrate any level of significant remediation while actually demonstrating an increase in the degree to which the misconception was held.Implications presented by the data indicate interdisciplinary approaches to learning to be far more effective in establishing higher levels of comprehension and understanding. Through the combination of the innate behaviorial characteristics of elementary students and the connecting relationships of academic disciplines, presentation of instructional materials will generate higher levels of interest and enthusiasm within both students and teachers. The resultant effect being a more positive learning environment and an increase in achievement. / Department of Biology

The possibility that visual thresholds fluctuate in a circadian rhythmic (twenty-four hour) pattern was examined. Subjects were tested at 0400h, 1000h, 1600h and 2200h in a 30 minute dark adaptation procedure using a von Békésy tracking method. Two experiments were performed; the first tested cone functions with a red 1 degree monochromatic test stimulus located ten degrees nasally. There were no sex differences for the ten male and female subjects used in this study. However, there were time of day differences with higher thresholds at 1000h than at any other time. The second experiment examined both rod and cone thresholds with a heterochromatic test stimulus. Sex differences were found 'for the 10 male and 10 female subjects. The rods for males were found to exhibit significantly higher thresholds at 1000h than any other time. There were no significant differences for females. The null results for females may be due to an influence of the menstrual cycle on vision. The rod differences for males is thought to occur because of rod outer segment shedding which also has a circadian rhythm. A circadian rhythm questionnaire was administered to the subjects and it was found that morningness and vigorousness related to visual thresholds. / Master of Science
