Description: Approximately 20% of children experience serious mental health problems severe enough to meet diagnosis criteria, and less than one third of these children receive the services they need. Identifying effective school-based counseling interventions provides a viable and accessible solution, especially for families with financial barriers. This randomized, controlled outcome study examined the effectiveness of Adlerian play therapy (AdPT) compared to reading mentoring (RM) with 58 kindergarten through third grade students who qualified with clinical levels of disruptive behavior in the classroom. Participants were identified as 48% Latino, 33% European American, and 19% African American. Approximately four-fifths of participants were male. Children were randomly assigned to AdPT (experimental group) or RM (active control group) for 16 sessions of treatment. Children in both groups participated in twice weekly, individual, 30-minute interventions that took place in their schools. Results from a two (group) by two (repeated measures) split plot ANOVA indicated that, compared to the RM group over time, the AdPT group demonstrated statistically significant improvement on (a) disruptive behaviors in the classroom, as directly observed by objective raters and as reported by teachers, and (b) stress in the teacher-child relationship, as reported by teachers. Teachers and observers were blinded to children's treatment ...

Description: The purpose of this study is to find out what students in the first chemistry course at the undergraduate level (general chemistry for science majors) know about the affordances of instrumentation used in the general chemistry laboratory and how their knowledge develops over time. Overall, students see the PASCO™ system as a useful and accurate measuring tool for general chemistry labs. They see the probeware as easy to use, portable, and able to interact with computers. Students find that the PASCO™ probeware system is useful in their general chemistry labs, more advanced chemistry labs, and in other science classes, and can be used in a variety of labs done in general chemistry. Students learn the affordances of the probeware through the lab manual, the laboratory teaching assistant, by trial and error, and from each other. The use of probeware systems provides lab instructors the opportunity to focus on the concepts illustrated by experiments and the opportunity to spend time discussing the results. In order to teach effectively, the instructor must know the correct name of the components involved, how to assemble and disassemble it correctly, how to troubleshoot the software, and must be able to replace broken or missing components ...

Description: This study was developed to examine the motivations of individuals who chose alternative routes to teacher certification and what they believe were the strengths and weaknesses of their alternative certification preparation (ACP). Data accrued from this study were based on a 55-item online survey and participant information from an online focus group. The study compared the differences between general and special educators in regards to the motivating factors affecting the decision to become a teacher, remain a teacher, and in choosing a non-university-based ACP, as well as the perceived strengths and weaknesses of the ACP. The results from the survey suggest there are differences in the motivating factors affecting general and special educator's decision to become a teacher and to remain a teacher. Additional survey results suggest there are no differences in the reason these two groups chose a non-university-based ACP. The results of the survey and the online focus group were comparable for these two groups. The remainder of this dissertation includes a review of literature related to teacher shortages and teacher preparation including alternative certification. Additionally, information on the results and analysis of the study are discussed, as well as recommendations for future research.

Description: A choice paradigm was used to evaluate allocation of interlocking behavior of two groups of two participants between responses having operant consequences only and responses having cultural consequences. In a discrete trial BABABAB design, each participant could select one of three options, which delivered either 3 or 5 points. In B (cultural consequence) conditions, two of the options had additional effects: the 3-point option also added 3 points to the other participant's earnings, and one of the 5-point options also subtracted 5 points from the other participant's earnings. The third option was unchanged in both conditions and delivered 5 points to the participant who selected it. Results indicated that participants in both groups initially frequently produced response combinations that earned 8 points for one or the other individual (and 0 or 3 points for the other), but allocation of responding increasingly changed to combinations that produced 6 points for each individual. This shift in performances away from maximum individual reinforcement towards maximum group reinforcement indicates cultural contingencies did not act in concert with operant contingencies, suggesting they are different mechanisms of selection.

Description: Since its premiere in 1878, Antonín Dvořák’s Piano Concerto in G Minor has been underrated and held in low regard by musicologists, critics, performers and audiences alike. Vilém Kurz (1872-1945), a Czech pianist and pedagogue, revised and reworked the piano solo part to incorporate what he considered to be added brilliance and pianistic effectiveness. However, the revised version has not increased the popularity of the work. In recent decades, this concerto has begun to appear more often in the programs and recordings are currently available, utilizing either the original piano part or Kurz's revision or a combination of both. In order to gain a broader analytical perspective and achieve a more authentic interpretation of the piece, a thorough understanding of the relation between Dvořák’s work and Kurz's revisions is indispensable. This study examines these adaptations and compares them with Dvořák’s scoring in order to gain further insight to Kurz's musical intent and pianistic aims. Examples from all movements are evaluated vis-à-vis the original to determine their purpose and musical validity.
