A common belief in United States culture is that "...sports can provide opportunities for personal growth and social development." (Ewing, 1997). Unfortunately, more recent research has suggested there is a growing trend to the contrary. As a result, those whose work it is to develop an athlete's morality should seek out strategies that have been evaluated for their effectiveness. Therefore, the purpose of this quantitative study was to examine the degree to which participating in Positive Coaching Alliance (PCA) Workshops affect secondary school athletes' level of moral knowing. The research questions for this dissertation were: 1. To what degree was there a statistically significant change in moral knowing for ninth graders that attended a Positive Coaching Alliance workshop? 2. To what degree was there a statistically significant change in the Social Character or Moral Character components for ninth graders that attended a Positive Coaching Alliance workshop? 3. To what degree was there a statistically significant difference in the moral knowing for twelfth graders that attended multiple Positive Coaching Alliance workshops as compared to twelfth-graders who did not? 4. To what degree was there a statistically significant difference in the Social Character or Moral Character components for twelfth graders that attended a Positive Coaching Alliance workshop as compared to twelfth-graders who did not? The archival data used for this study was collected during the fall of 2016 at a private sixth through twelfth grade coeducational day school in the Southeast United States. This data was collected as part of the school's efforts to assess the efficacy of a program that had been implemented for the past three years. Two hundred and one ninth- and twelfth-grade students participated in the survey. The Rudd-Stoll-Beller-Hahm (RSBH) Value Judgment Inventory from The Center for Ethics at the University of Idaho was the statistical instrument used to measure secondary athletes' moral knowing for this research. Research question one saw the only statistically significant change in data. Results from the Welch Test for all ninth graders pre and post-test data provide statistically significant evidence that the mean score is different among the groups. The group that included athletes who attended a PCA Workshop had a positive difference in scores from pre-test to post-test, while the other two groups' service club members and non-athletes had lower scores on average. While there was no statistically significant evidence that supported research questions two through three, the findings for these three research questions provided insight that can assist educators in charge of the moral development of athletes. This study's focus was to evaluate one strategic intervention strategy that assists in the moral knowing of students. By determining the effectiveness of Positive Coaching Alliance Triple Impact Competitor workshops on the moral knowing of secondary athletes, educators can be better equipped to address the need for the moral development of their students and thus provide an education that benefits both the student and society.
