Abstract
Difficulties associated with the comprehension of Hemodynamics in the Human Anatomy and Physiology course at NYCTC, had been the consensus of the course committee and large sector of the student clientele for some time. This had been attributed to the physical and mathematical principles involved in the topic. In addition, the material on the topic in the text used was found to be inadequate. The purpose of the study was to develop, implement and evaluate an audiotape and accompanying handouts on the topic as a supplementary teaching aid in the health science learning center of New York City Technical College. Twenty students from one section of the course who were exposed to classroom instruction only, were used as the control group. Twenty students from another section of the same target group, who were exposed to classroom instruction and the teaching aid, were used as the experimental group in the study. An independent t test was conducted in the study to determine whether there was a significant difference between the examination grade on hemodynamics of students who were exposed to the teaching aid and the mean examination grade of students who were not exposed to the teaching aid. The Null Hypothesis was stated as something, and the alternate hypothesis was stated as something else. The critical t value for a two tailed test was established and at a significance level of .05. The calculated value was compared to the critical value to determine whether or not the hypothesis was to be rejected. The results of the study indicated that the calculated value was greater than the critical value at a significance level of .05, thus rejecting the no hypothesis. The findings indicated that there was a significant difference between the main examination grade on hemodynamics of students exposed to the teaching aid and the main examination grade on hemodynamics of students not exposed to the teaching aid. The results further indicated the effectiveness of the teaching aid. As a result of the study, it was recommended that the teaching aid be implemented permanently in the HSLC, and more students be conducted to ascertain further validity of the instrument. The development of similar teaching aids on other topics of interest, as well as exploring avenues of funding for the development of additional teaching aids were recommended.
