This study addresses a significant gap in educational research by employing statistical methods to measure the sequencing of different components and content topics in textbooks. It is well-documented that the structure and sequencing features of textbooks play a crucial role in enhancing students' learning. However, existing literature has…

The purpose of this study was to determine if the Summit Learning Platform, a type of Intelligent Tutoring System, has a positive association with mathematics achievement of high school students in grades nine through eleven. The study was conducted in a Midwest suburban school district among three high schools within the same district. Further, a…

There is a lack of valid and reliable low cost observational instruments to measure moderate to vigorous physical activity (MVPA) in school physical education (PE). The participants in this study were third to tenth grade boys and girls from a south Texas school district. The SAM (Simple Activity Measurement) activity levels were compared with…

This study was conducted to obtain information about a mentoring program through the eyes of eleventh and twelfth grade student mentors. These students were able to tell what needed to be known about the strengths and weaknesses of this mentoring program and what they felt needed to be done to make the program more effective and meaningful. This…

The high school graduation rate in Tennessee has failed to meet the state required benchmark of 90%. The state graduation rate in 2003 was 76%, in 2004 it was 75.7%, 2005 it was 77.9%, and in 2006 it was 80.7%. The Tennessee State Department of Education is searching for effective methods to increase the graduation rate for Tennessee high schools.…

This quasi-experimental study measured the effectiveness of a locally created summer Algebra readiness program in a large suburban high school district in New Jersey. Incoming ninth grade students who were not ready for high school algebra were invited to participate in the summer program. The program was designed to provide access to more…

Using data from a nationwide, large-scale experimental study of the effects of a connected classroom technology on student learning in algebra (Owens et al., 2004), this dissertation focuses on challenges that can arise in estimating treatment effects in educational field experiments when samples are highly heterogeneous in terms of various…

In this study, I developed three methods for the assessment of high-school students' environmental decision-making skills. The three methods were developed based on perspectives of decision-making expertise in psychology and are named "Satisfying Results," "Coherence," and "Process Decomposition." Satisfying Results looked directly at the choices…
