While much of the literature regarding college readiness focuses on student-specific factors, such as the individual's academic achievement; scores on college readiness assessments; and high school GPA, more research is needed to understand which school-level factors have the most influence on the percentage of college-ready graduates. The purpose of this research study was to explore the impact of various school-level factors (i.e., student demographics, college entrance exam facts, course offerings, and school characteristics) on the percentage of college ready graduates from Texas public high schools serving Grades 9-12 over a 3-year period. A multiple regression analysis conducted for each year's data resulted in three regression models, which identified various predictors (e.g. per-pupil instructional expenditures, teacher years of experience, taking advanced and/or dual credit coursework) of the percentage of college-ready graduates for schools accounting for 91.7%, 79.5%, and 65.6% of the explained variance in 2013, 2014, and 2015, respectively. Findings from this study provide educational leaders with data that could help them to make better-informed decisions regarding potential college readiness initiatives that, ultimately, could improve student performance.

Doctor of Education / Department of Educational Leadership / Teresa Miller / The purpose of this research proposal was to investigate school-level factors identified by Marzano (2003) perceived to have contributed positively to student achievement in one charter school. The researcher noted the following issues related to charter schools and student achievement: The data on student achievement were mixed; limited research existed on student achievement using the school -level factors identified by Marzano (2003); limited case studies existed comparing school-level factors and student achievement for charter schools. Using the case study format, the researcher investigated perceptions regarding school-level factors perceived to have increased student achievement in one charter school in Kansas over a five-year period from 2005-2008. The case study was accomplished through the collection, analysis, and interpretation of data from multiple sources to include researcher observations, key informant interviews, and analysis of archival documents. After conducting the research, it was determined that while there wasn’t a deliberate attempt to use the factors by Robert Marzano (2003), the school-level factors were used by Dartmouth Charter School did impact student achievement as evidenced by stakeholder interview, Kansas Reading Assessments, and archival data sources. A case study confirmed the presence of several aspects of the school-level factors of a guaranteed/viable curriculum, challenging goals and effective feedback, parental and community involvement, a safe and orderly environment, and collegiality and professionalism, which were perceived by stakeholders as contributing to increased student achievement over the five-year period of operation.

The purposes of this study were to explain the development and validation of a new instrument for assessing elementary students&rsquo / views of the Nature of Science (NOS) and to investigate student and school level factors that help to explain the difference in NOS views. The sample included 3,062 elementary students elementary schools located in &Ccedil / ankaya. Different from these students, 782 elementary students were the sample for the first focus of this study. The Nature of Science Instrument, Learning Approach Questionnaire and Achievement Motivation Questionnaire were administered to the students. Hierarchical Linear Modeling (HLM) was selected as a modeling technique because of the nested structure of the data sets. This study provides an instrument for measuring elementary student views of the NOS regarding four dimensions. In this study, students had different views regarding each dimensions, therefore, many variables have been shown to relate to different dimensions of NOS. This study has established the importance of student socio-economic background with varying learning approaches, self-efficacy, and motivational goals in forming their NOS views. Findings revealed that quality of the physical infrastructure of schools and quality of educational resources in school, parent educational levels, student achievement, self efficacy, experience with meaningful learning, and learning goal orientation are positively related to student NOS views in many different dimensions. Additionally, performance goal orientation and rote learning approaches have negative relationship with different dimensions of student NOS views.

This study investigates the students&rsquo / characteristics and school characteristics and their influences on scientific literacy skills of 15-year-old students across Turkey, Canada, and Sweden, through the use of data from Organisation for Economic Co-operation and Development&rsquo / s (OECD&rsquo / s) Programme for International Student Assessment (PISA) 2006. The purpose of this study is to gain a more complete understanding of the effect of human and physical resource allocations and their interaction on students&rsquo / scientific literacy skills using Hierarchical Linear Modeling (HLM) techniques. By PISA 2006 results, in terms of scientific literacy, Canada is a high performing country whereas Turkey is far below the average and Sweden has a rank in the average. For modeling scientific literacy, student-level characteristics determined by student questionnaire, and school-level characteristics determined by school questionnaire were used. Results of the present study indicated that there were significant between-school differences in scientific literacy skills of students for all three countries. Turkey had the highest between-school variance and it was more than half of the total variance whereas in Canada and Sweden they were far lower. School type and size were common school factors affecting students&rsquo / scientific literacy skills in Canada and Sweden / however, in Turkey school admittance policies, educational resources, science promotional activities, and teacher qualities were school characteristics which have impact on scientific literacy. Enjoyment of learning science, self-efficacy in science, general value given to science, awareness of environmental issues, responsibility for sustainable development, and confidence in use of information technologies were common student factors affecting development of scientific literacy skills in the three countries. Finally, in all three countries cross-level interactions of student and school characteristics for developing scientific literacy skills were observed.

The purpose of the present study is to gain a more complete understanding of the impact of human and physical resource allocations and their interaction on students&rsquo / mathematical literacy skills across Turkey, member and candidate countries of European Union through the Programme for International Student Assessment (PISA) 2003. Hierarchical linear modeling (HLM) techniques were used separately for three different cultural settings using the database of Programme for International Student Assessment (PISA) 2003. The results indicated that students in Turkey, member and candidate countries of European Union who performed higher on the mathematical literacy assessment tended to have the following characteristics: (1) enrolled at higher grade levels, (2) more educational resources at home, (3) higher levels of mathematics self-efficacy, (4) lower levels of mathematics anxiety, (5) more positive self-concept in mathematics, (6) less preferences for memorization strategies, and (7) more positive disciplinary climate in mathematics lessons. As the performance of schools were considered, the higher average mathematics self-efficacy of students, the higher the mean school mathematical literacy performance. The influence on mathematical literacy assessment varied from school to school with respect to grade level and disciplinary climate in mathematics lessons in Turkey and European Union countries, with respect to grade level, mathematics self-efficacy, and disciplinary climate in mathematics in European Union candidate countries. Moreover, school size and mathematics student-teacher ratio at school influenced the disciplinary climate in mathematics lessons in Turkey / academic selectivity of the school influenced the grade level and mathematics self-efficacy in the candidate countries of European Union.
