"There are many factors that influence the achievement of school children; however it is rather difficult to determine the effect of each because of the close relationship and probable overlapping of the various factors. The problem in this study is to determine what effect the size of the school, training and qualifications of the teachers, and sex have upon the achievement of elementary school children in Denton County. A few of the main factors involved in this study will be examined and statistically presented, so as to show their relation to the achievement of the rural children in Denton County, as revealed through the Harlow achievement tests."-- leaf 1.

While the idea of source or teacher credibility dates back to the Greek philosopher, Aristotle, research to connect this perceived credibility with individual affective and cognitive growth is a more recent phenomenon. In 2009, a credibility learning model connecting perceived credibility to cognitive learning with university-aged subjects was established. In contrast, this research project focused on determining a link between K-12 students' perception of teacher credibility, as determined by a student survey, to cognitive academic achievement as rated by a standardized test, the State of Texas Assessment of Academic Readiness (STAAR). The survey data were obtained through a pre-existing campus climate survey that was created to assist campus and district administrators in determining campus needs and developing a campus improvement plan. The assessment data were obtained through the Texas Education Agency database. The data were analyzed using quantitative research methods, including traditional univariate and multivariate statistical techniques such as principal component analysis, chi-square tests for independence, and binomial logistic regression. The findings of the study revealed no link between the survey instrument used and student academic achievement on the STAAR reading and mathematics assessment. The survey used did not align with the review of literature regarding student's perception of teacher credibility nor did it align with students' academic success. Therefore, survey findings were not correlated with STAAR results.

This thesis examined the impact of teacher quality and the socioeconomic status of students on school performance on the Texas Assessment of Knowledge and Skills Test. The data were obtained from the Academic Excellence Indicator System (AEIS) 2005-2006 Report. Disparities in education were used to examine the use of teacher quality in the No Child Left Behind Act of 2001. A multiple regression model was used and included other factors such as socioeconomic status of students, teacher salary, school funding, and student-teacher ratio. Using an ordinary least squares regression, I found that socioeconomic status of students had the most significant impact school performance. Two other variables, teacher salary and student-teacher ratio, had a significant effect on school performance suggesting alternative means of eliminating inequality in education.

The problem of the study was determining the supportive conditions related to instructional rounds (rounds) to understand better what conditions may allow for sustained systemic improvement over time. Three Texas school districts were studied to understand the perceptions of district leaders, principals, teacher leaders, and teachers with regard to the sustainability of instructional rounds as a systemic improvement practice, the supportive conditions necessary for sustainability, the salient characteristics that differentiated rounds from other improvement practices, and the potential of rounds to build organizational capacity. Observation of network rounds visits and document analysis was conducted to determine alignment of perception with observation and documents. Findings include perceptions, themes, and critical factors for the sustainability of rounds as an effective systemic improvement practice. Supportive conditions emerged as the most significant perception expressed by the participants. Implications for action for school districts beginning or continuing implementation of instructional rounds are suggested based upon findings from participant perceptions and observation of networks. Suggestions for future research are shared. With supportive conditions in place, instructional rounds has the potential to serve as an effective systemic improvement practice.
