This study examined the effects of the supervisory process on classroom teaching. Through examination of the supervisory conference setting, this study examined whether effective supervision required supervisors who practiced certain strategies as they dialogued with teachers in the conference, or whether discussion of research-verified knowledge about teaching and learning alone was sufficient to bring about an improvement in classroom teaching practice. This study also examined the effects of an intervention on school principals in their performance of the supervisory task. That is, the study sought to determine if supervisors transferred the research-verified knowledge and/or process strategies presented in workshop programs to the supervisory task, and, if so, what effect, if any, this had on teachers' classroom teaching performance (classroom management practices). The research design was a case study of three supervision dyads which included two different treatments. Pre- and post-test data sources included supervisee classroom management performance, supervisory post-observation conferences, and conference participants' independent post-conference reactions. Data analysis explored the relationships between classroom observation data and supervisory conference data, in each case, for evidence of improved practice on the part of the teacher in the classroom and on the part of the principal in the supervisory conference. The relationships among the teacher's classroom management practices, the supervisor's process strategies, the substantive content focus of the conference, and the differential treatments (workshops) received careful examination. Through this approach the effects of many variables on teachers' classroom management performance were explored. The supervisory experience appeared to be affected by the experience and/or professional confidence levels of both supervisors and supervisees, the openness of both supervisors and supervisees (as evidenced in the interactive nature of the conference), the level of content knowledge and supervisory process strategies employed by the supervisor in the conference setting, and the facilitating role played by the supervisor. Where teachers were experienced and professionally confident, they appeared to find the supervisory process less threatening, and were more open and interactive in the conference setting, rendering the supervisory experience more effective. Where supervisors were perceived as less threatening (low in experience and/or level of confidence), more knowledgeable, and sincere in their facilitating efforts (process strategies), the supervisory experience also appeared more effective. The effects of the treatments on supervisors also appeared to be related to their level of experience and/or confidence, as well as their degree of openness. While the supervisors in this study transferred the knowledge and/or strategies learned to their performance of the supervisory task, the levels of application differed considerably. The implications for practice, based on the limited findings of this study, suggest that the improvement of current supervisory practice may require a combination of several staff development programs designed to provide both partners involved in the supervisory process with opportunities to develop and/or enhance both the knowledge and/or the skills that appear necessary for effective supervision. / Education, Faculty of / Educational Studies (EDST), Department of / Graduate

<b>Introduction:</b> Children's social, emotional, and behavioural difficulties are associated with reduced academic performance, stressed teacher-child relationships, and other negative academic and life outcomes. The Incredible Years Teacher Classroom Management (IY TCM) programme is one intervention developed to address problematic behaviours via training teachers to use positive and proactive management strategies. The overall aim of this DPhil is to use the Incredible Years Teacher Classroom Management programme as a case study for applying mixed methods at the systematic review level to ascertain what is known about both the programme's effectiveness and how people experience the course, and subsequently to use the systematic review's findings as a springboard (rather than as an end goal) for more exploratory research into 'for whom' the programme might work. <b>Method:</b> Study One is a mixed methods systematic review of IY TCM. It applied multilevel meta-analysis to RCT outcome data and grounded theory meta-synthesis to interview and focus group data on stakeholders' experiences of IY TCM. Quantitative and qualitative findings were cross-synthesised and mapped using an integrative grid. Study Two moves the field forward by filling a gap in the evidence base, as identified in Study One. Semi-structured telephone interviews were conducted with special educational needs coordinators (SENCos) across Devon, exploring the acceptability and appropriateness of expanding IY TCM to the subgroup of children with special educational needs (SEN) in mainstream schools. Data were analysed thematically and mapped onto IY TCM content. <b>Results:</b> In Study One, nine studies reported across 14 papers met inclusion criteria for either quantitative or qualitative strands of this systematic review. Multilevel meta-analysis of RCTs (n=4) indicated that the programme produced teacher- and child-level results in the desired directions. Clear trends across all measured outcomes favoured the intervention group over the treatment-as-usual comparison. Qualitative meta-synthesis (n=5) illuminated a cyclical learning process and broader conceptualisation of teacher and child outcomes than was evident in the quantitative evidence. Notably, RCT data on teacher outcomes were limited to self-reported or observed behaviours, while teachers described other benefits from IY TCM including increased knowledge and emotional well-being. Cross-synthesis of findings from the two review strands highlighted harmony across the RCT and qualitative evidence but also a number of areas in which constructs that were prioritised by one type of research were not integrated into the other. Study Two generated classroom management strategies from SENCos, which aligned closely with strategies taught in IY TCM, indicating that IY TCM would be both acceptable and applicable (if not sufficient) for use when working with children identified with SEN and behavioural difficulties in schools. <b>Discussion:</b> Based on the positive effects of implementing IY TCM despite very few studies to power analyses, the programme appears to offer tangible benefits to both teachers and children. It is possible that results are underestimated due to limited types of outcomes measured and absence of experiential data from additional stakeholders (e.g., parents). Depending on current provision of special educational needs services, schools operating inclusion models are likely to find these strategies beneficial for children identified with SEN, and this subgroup should be explicitly examined in future IY TCM studies.
