Online education is becoming an increasingly important component of higher education. The Sloan Foundation 2010 Survey of Online Learning reports that more than 30% of all students take at least one online course during their college career. Because of this, attention is now turning to the quality of student outcomes that this instructional method…

This dissertation is a combination of two research areas, experimental physical chemistry, Chapters I to V, and chemical education, Chapters VI to VII. Chapters I to V describe research on the water-mediated chemistry of oxidized atmospheric molecules and the impact that water has on the spectra of these environmental systems. The role of water…

Systemic assessment questions (SAQs) are novel assessment tools used in the context of the Systemic Approach to Teaching and Learning (SATL) model. The purpose of this model is to enhance students' meaningful understanding of scientific concepts by use of constructivist concept mapping procedures, which emphasize the development of systems…

Many educators are reluctant to use scripted instruction, reporting that scripts are mechanical in nature and only appropriate for low-level skills. This study sought to investigate the impact of a supplemental program's script on the rate of on-task and off-task instructional opportunities offered by the instructor for students to practice the…

Purpose: The purpose of this study was to conduct an in-depth investigation of an executive team, to determine which internal and external factors impacted the team and to determine in what ways action research interventions improved the team's effectiveness. Methodology: The subjects in this study were seven members of a school district…

The purpose of the present study was to identify components of an optional mock exam review session (e.g. requiring students to write answers, providing students grading keys for questions) responsible for improvements in student performance on application-based short-essay exams in an undergraduate behavior modification course. Both…

This study investigates how teachers interact with immigrant-origin youth in school-based contexts of reception that mediate youth's educational opportunities. One understudied context is sheltered instruction, where English learners (ELs) are placed into separate content-area courses to target their linguistic needs. This qualitative study…

Achievement goal theory is considered to be a well-researched field. However, this research has been primarily through surveys, and not enough attention has been paid to the cognitive aspects of how children perceive goals. Additionally, the mastery-avoidance construct is relatively new to the achievement goal literature, with little research to…

This paper investigates teaching practices at the Australia-Pacific Technical College (APTC), which comprise a unique official development assistance (ODA) program funded by the Government of Australia (GoA) and managed through the Australian Agency for International Development (AusAid) with the aim of training and equipping workers from the…

Science, Technology, Engineering, and Mathematics (STEM) education has become a key focus in the U.S. government's public education agenda. Many STEM degrees require the successful completion of undergraduate introductory organic chemistry (O-Chem), which is notorious for its difficulty and high attrition rate. Concept Maps (CM) have been used as…

This purpose of this study was to investigate the effectiveness of the North Carolina charter schools. The variables were chosen based on the researcher's inference from literature reviews discussing common factors from qualitative charter school studies. The indicators were used to determine if charter schools could be categorized as effective or…

Purpose: The purpose of this investigation was to examine the impact of Chromosome 4p- syndrome on the communication and expressive language phenotype of a large cross-cultural population of children, adolescents, and adults.
