The goal of this Dissertation in Practice was to design a School Improvement Plan focused on improving reading performance of African American students at Suburban Middle School (SMS). The problem of practice was that African American students at Suburban Middle School have performed significantly lower than their White peers over the course of the 2009-2013 school years in reading performance. The reading deficiencies of African American students needed to be directly addressed in a new School Improvement Plan (SIP). The literature review of this study found that there are many different components that influence the reading performance of African American students. For this Dissertation in Practice, a new School Improvement Plan focused primarily on 6 different areas will be the end result. The components that will be examined are: 1) school climate, 2) utilization of data, 3) parental involvement, 4) professional development, 5) instructional strategies, and 6) collaboration. While these are the 6 key elements of successful models, there were also additional sub groupings within each element that also had an influence on student achievement levels. In addition to examining previous School Improvement Plans at SMS, the end result and final deliverable was a School Improvement Plan designed to close the existing achievement gap in reading between African American students and their peers at SMS. Suggested use for the new model of the School Improvement Plan was to focus specifically on the 6 key elements to address the reading performance of African American students.

The learning environment has been the focus of considerable educational research over a long period of time. The study reported in this thesis utilises the perceptions of 208 junior science students from a North Queensland state secondary school to inform classroom environment improvement plans developed and implemented by their teachers' in an attempt to improve the cognitive and attitudinal outcomes of the students. The five stage process on which the study is based combines theory and practice in providing the participating teachers with a structured means of bringing about change in their classrooms. Students' perceptions of actual and preferred teacher interpersonal behaviour and the laboratory learning environment are measured using the QTI and SLEI respectively. Particular aspects of teacher interpersonal behaviour and the laboratory learning environment are targeted for change through the classroom environment improvement plans. The study identified which aspects of the learning environment had changed after a period of intervention. It also identified associations between students' perceptions of aspects of their laboratory learning environment and attitudinal outcomes as well as associations between teacher interpersonal behaviours and attitudinal outcomes. While no direct associations were found between aspects of the laboratory learning environment or teacher interpersonal behaviours and cognitive outcomes, students' cognitive outcomes did improve over the duration of the study thus supporting a previously established link between student attitudes and cognitive outcomes.
