This was a single case qualitative study designed to investigate instructional leaders’ perceptions of the impact teacher quality has on students’ performance. Over the past three decades, various stakeholders have expressed concern regarding teacher quality as it relates to students’ performance. Therefore, there is an urgent need for quality teachers at all levels of the education system. This study was significant as it sought to add new information to the body of existing literature on the growing phenomenon of quality education by exploring the perceptions of instructional leaders on teacher quality and its impact on students’ performance. The main thrust is for quality teachers and quality teaching and a more robust education sector. Multiple forms of data collection were used and significant time was spent in the natural setting gathering information. Primary forms of data collection were interviews, observation and the examination of artifacts. In order to code the data, they were first divided into content unit which was coded in terms of the quality of effective teaching. Thus, content unit was used to analyze the data. As the researcher explored the perceptions of the instructional leaders on elements of teacher quality and students’ performance it became evident that there was no single element that constitute teacher quality. The researcher recommended that practice be data driven, bringing information based on elements of teacher quality and self- efficacy in particular to bear on instructional strategies. TEACHER QUALITY AND STUDENTS’ PERFORMANCE i Key terms: teacher quality, instructional leaders, self- efficacy, student performance. / Educational Leadership

Transition programs designed to ease the middle to high school transition are becoming a necessity in high school because ninth grade is deemed as a critical year for determining students’ success in high school. Few studies examined transition programs’ impact on students’ educational outcomes, and transition research is typically conducted in inner-city or urban settings. The purpose of this case study was to examine the impact of a full transition model program on ninth grade students’ performance in a rural high school. A comparison of the students who participated in the transition program to those who did not was examined by using a mixed method approach. The qualitative data consisted of the ninth grade teachers and administrators’ perceptions and the program documents. The quantitative data consisted of a chi-square analysis of the transition and nontransition program students’ pass rate of high stakes tests, earned credits, retention status, out-of-school suspensions, dropout status, and attendance. The study also examined if specific groups of students as categorized by race, gender, and socioeconomics were impacted more by the transition program. The findings of this study suggested that the transition program may have eased the transition by providing support to ninth grade students to improve their conduct. The quantitative evidence does not show other significant benefits from the transition program, however. Improving academic performance still remains a challenge for this rural high school. / Ph. D.

The purpose of this study was to determine the odds of school organization features predicting schools meeting district or state performance goals. The school organization features were organizational complexity, shared decision making, and leadership behavior. The dependent variable was school performance, operationally defined as a principal's yes response or no response to the question, "did your school meet district or state performance goals." The independent variables representing organizational complexity were school size, diversity of role, span of control. The independent variables representing shared decision making were curriculum influence, policy influence, and professional development influence. The leadership behavior feature was a composite variable. The percent of school lunch was the covariate, as determined by the percentage of students receiving free lunch and reduced price lunch. The sample for this study was taken from the 1999-2000 Schools and Staffing Surveys (SASS) Public-Use Data (NCES: 2004-372) collected by the National Center for Education Statistics (NCES). The sample consisted of 5,312 public schools and 5,312 public school principals. Data from the SASS Public School Questionnaire and the SASS Public School Principal Questionnaire were used for the data analysis. The methods of data analysis consisted of the identification of indicator variables from SASS, the development of scales, and the fitting of a parsimonious logistic regression model. A principal components analysis was used to extract patterns of association among the indicator variables, shared decision making and leadership behavior. The logistic regression analysis revealed that the best model for predicting the odds of whether schools would meet district or state performance goals consisted of the variables curriculum influence, policy influence, professional development influence, size, diversity of role, span of control, and the covariate, percent of free lunch. The significant variables were curriculum influence, policy influence, professional development influence, and span of control. The odds of school organization features predicting whether schools would meet performance goals was estimated to be .7243, which was less than one or less than chance. There were several limitations of this study that need to be considered when interpreting the results. / Ed. D.

Success rates for students in developmental education are dismal. The greatest need for developmental education instruction occurs in mathematics, where high numbers of underprepared students generate great concern and the need for substantial changes in higher education institutions. With higher rates of students requiring remediation in the community colleges, the identification of effective policies and practices in developmental education is necessary to increase the achievement rates of developmental education students, and more specifically developmental mathematics students. This study explored the relationship between developmental mathematics student performance and developmental education programs of the Urban Community College District colleges. In addition, this study set out to identify institutional characteristics between colleges whose developmental mathematics students met state mandated academic outcomes at higher rates than their sister colleges. / text

The purpose of this study was to analyze the impact of alternative school intervention on subsequent student performance. The literature review examined the history and development of alternative schools, the legislation pertaining to alternative schools, and related studies. The population consisted of students placed in the discipline alternative education program (DAEP) of an alternative school located in a large suburban school district in north Texas. Students placed in DAEP in the spring semester of 2001 in grades 7, 8, 9, and 10 were included in the sample. Data on student success was gathered for the one semester prior to placement (pre-intervention) and for the two semesters after placement (post-intervention). Student success was measured in terms of course grade averages and attendance. The student sample was divided into the following subgroups: grade level, sex, ethnicity, and qualification for the school meal program. The students' grade averages were compared within the subgroups utilizing a one-way analysis of variance (ANOVA). Tukey's post hoc comparison was utilized on the groups when ANOVA was found to be significant. The students' attendance was analyzed by comparing the proportion of days attended in each of the three semesters included in the study. A normal test of two independent means was conducted on the attendance proportions. The results of the study indicated the following significant findings (p <. 05): the eighth-grade students' grade averages were significantly lower in the second post-treatment semester, the 7th-grade students had lower attendance in the first post-treatment semester, the 8th-grade students had lower attendance in the second post-treatment semester, and the 10th-grade students had higher attendance in the first post-intervention semester. The female students' attendance was higher in both post-intervention semesters and significantly higher in the second. A discussion of the dropout rate for this group and recidivism to DAEP was included.

The problem with which this investigation is concerned is that of determining the influence of instructors' written comments on the test performances of students in selected college subjects. The students were from one university and one junior college. The written comments were designed to be positive in nature and to encourage better future test performances by students. The comments were made in regard to the letter grades received by the students and were placed only on major (as defined by each instructor) objective tests.

This study evaluated 227 students attending 12 classes of the Apprentice Medical Services Specialist Resident Course. Six classes containing a total of 109 students took the Block One Tests in the traditional paper and pencil form. Another six classes containing a total of 118 students took the same Block One Tests on computers. A confidence level of .99 and level of signifi­cance of .01 was established. An independent samples t-test was conducted on the sample. Additionally, a one-way analysis of variance was performed between the classes administered the Block One Tests on computers. Several other frequencies and comparisons of Block One Test scores and other variables were accomplished. The variables examined included test versions, shifts, student age, student source, and education levels. The study found no significant difference between test administration modes. This study concluded that computer-administering tests identical to those typically administered in the traditional paper and pencil manner had no significant effect on achievement. It is important to note, however, that the conclusion may only be valid if the computer-administered test contains exactly the same test items, in the same order and format, with the same layout, structure, and choices as the traditional paper and pencil test. In other words, unless the tests are identical in every possible way except the actual test administration mode this conclusion may not be applicable.

Students’ academic self-concepts (ASC) and their orientation towards self-regulated learning are important elements of success. Despite this fact, little work has been conducted exploring these areas medical students. Given the shifting priorities of medical education toward competency-based education and self-directed learning, the goals of this study were to validate an existing measure of ASC and to improve our measurement capabilities for understanding the Master Adaptive Learner (MAL). Evidence for validity and scale reliability was collected for the ASCS with this novel population and a range of motivational and self-regulative variables (Goal orientation, academic emotion regulation, and lifelong learning) were analyzed and reduced to produce a single scale for MAL. Surveys were administered to 203 medical students at an urban, Mid-Atlantic medical school and students’ grades were linked to survey responses. Results of a confirmatory factor analysis indicated that the original factor structure was not a good fit to the data for the current data. An exploratory factor analysis (EFA) was conducted to identify which structure fit better, and while a three-factor structure was produced, only one factor met reliability standards. This factor, confidence, was merged with items from the other surveys, and reliability scores for a composite MAL scale were identified. Based on these findings and the result of an EFA, the total item pool was reduced from 83 to 25. These 25 items discriminated between two clusters of students: MALs and others. Students’ membership in the MAL cluster predicted greater performance on the first exam in medical school, but not on any other grade outcomes. These results provide early evidence for the continued study of MAL and motivation in medical school, which will help researchers and curriculum designers support the development of future physicians.

Scientific reasoning and writing skills are ubiquitous processes in science and therefore common goals of science curricula, particularly in higher education. Providing the individualized feedback necessary for the development of these skills is often costly in terms of faculty time, particularly in large science courses common at research universities. Past educational research literature suggests that the use of peer review may accelerate students' scientific reasoning skills without a concurrent demand on faculty time per student. Peer review contains many elements of effective pedagogy such as peer-peer collaboration, repeated practice at evaluation and critical thinking, formative feedback, multiple contrasting examples, and extensive writing. All of these pedagogies may contribute to improvement in students' scientific reasoning. The effect of peer review on scientific reasoning was assessed using three major data sources: student performance on written lab reports, student performance on an objective Scientific Reasoning Test (Lawson, 1978) and student perceptions of the process of peer review in scientific community as well as the classroom. In addition, the need to measure student performance across multiple science classes resulted in the development of a Universal Rubric for Laboratory Reports. The reliability of this instrument and its effect on the grading consistency of graduate teaching assistants were also tested. Further, application of the Universal Rubric to student laboratory reports across multiple biology classes revealed that the Rubric is further useful as a programmatic assessment tool. The Rubric highlighted curricular gaps and strengths as well as measuring student achievement over time. / This study demonstrated that even university freshman were effective and consistent peer reviewers and produced feedback that resulted in meaningful improvement in their science writing. Use of peer review accelerated the development of students' scientific reasoning abilities as measured both by laboratory reports (n = 142) and by the Scientific Reasoning Test (n = 389 biology majors) and this effect was stronger than the impact of several years of university coursework. The structure of the peer review process and the structure of the assignments used to generate the science laboratory reports had notable influence on student performance however. Improvements in laboratory reports were greatest when the peer review process emphasized the generation of concrete and evaluative written feedback and when assignments explicitly incorporated the rubric criteria. The rubric was found to be reliable in the hands of graduate student teaching assistants (using generalizability analysis, g = 0.85) regardless of biological course content (three biology courses, total n = 142 student papers). Reliability increased as the number of criteria incorporated into the assignment increased. Consistent use of Universal Rubric criteria in undergraduate courses taught by graduate teaching assistants produced laboratory report scores with reliability values similar to those reported for other published rubrics and well above the reliabilities reported for professional peer review. / Lastly, students were overwhelmingly positive about peer review (83% average positive response, n = 1,026) reporting that it improved their writing, editing, researching and critical thinking skills. Interestingly, students reported that the act of giving feedback was equally useful to receiving feedback. Students connected the use of peer review in the classroom to its role in the scientific community and characterized peer review as a valuable skill they wished to acquire in their development as scientists. Peer review is thus an effective pedagogical strategy for improving student scientific reasoning skills. Specific recommendations for classroom implementation and use of the Universal Rubric are provided. Use of laboratory reports for assessing student scientific reasoning and application of the Universal Rubric across multiple courses, especially for programmatic assessment, is also recommended.

The primary purpose of this Delphi study was to determine which of the research-identified differentiated instructional elements are the most effective for improving student performance as perceived by secondary principals in 2A to 5A 2009 ―Exemplary‖ public high schools in Texas. A secondary purpose for this study was to determine what additional differentiated instructional elements are perceived by this study‘s targeted principals as being critical for student success. The researcher obtained feedback during three Delphi survey rounds from the twenty-four member expert panel regarding which of the research-identified differentiated instructional elements they perceived to be the most effective for improving student performance. The differentiated instructional elements presented in the survey were based upon a sound theoretical framework resulting from a review of existing research on differentiated instruction. After Round Three, consensus was reached, and the data collection period ended. Each of the surveys for the study, as well as the statistical analysis, can be found in the appendices of this dissertation. The findings of this study determined that using a variety of resources, as well as a variety of strategies, were the top-ranked research-identified differentiated instructional elements that the expert panel perceived to be the most effective for improving student performance. In addition, panelists agreed that the differentiated instructional elements already identified in existing research, as presented in this study, are comprehensive and sufficient for improving student performance. Without a doubt, the conclusions and recommendations of this study could extend the current knowledge base by promoting the use of the most effective research-identified differentiated instructional elements to improve student performance. Furthermore, the implications of the study will be invaluable for ongoing professional development, principal and teacher preparation programs, and for those in the field seeking to improve their daily educational practices for student impact.
