In the past the turnover rate among teachers had been relatively high, the attention of researchers shifted to factors culminating the high turnover rate among teachers. It was not known to what extent, if any, the predictor variables of mentoring modality and length of employment explained the variance in the criterion variable, teacher turnover…

This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…

As teachers in Georgia utilize formative assessments to ensure successful performance on the state mandated Criterion Referenced Competency Test (CRCT), it is essential that the data they receive from these assessments are accurate. This study examined the correlation between the computer-assisted instructional program, Classworks, and student…

Purpose: The purpose of this study was to evaluate the efficacy of the EMBRACE Spanish support intervention for at-risk dual language learners and to determine which verbal and nonverbal characteristics of students were related to benefit from the intervention. The first study examined oral language and reading characteristics and the second study…

The purpose of this quantitative study was to investigate the effectiveness of a system-wide Response to Intervention (RTI) program on the mathematical achievement of seventh and eighth grade students. The study consisted of five district schools with a total of 502 participants. The students were identified as belonging to one of two tiers, which…

Education is one of the most political topics of today and teachers need highly effective professional development training to meet the challenges required for educating all students with their diverse needs. The educational process is a very complex mission and teachers must work collaboratively to acquire new and effective methods and strategies…

The purpose of this study was to investigate whether the use of interactive Whiteboard technology in mathematics class could improve student achievement as measured by scores achieved on the South Carolina State Palmetto Achievement Test (PACT). The study examined fourth grade mathematics achievement test scores for students whose teachers used…

The purpose of this ex post facto study was to analyze archive data to investigate the effects of Read 180, a computer-based supplemental reading intervention, on students' academic achievement for the academic school year 2011-2012. Further analyses examined if influences existed in variables such as grade level, gender, and ethnicity of the…

The increasing demand for nontraditional courses acknowledges that individuals are not monolithic in their approach to learning. The uniqueness of an individual's learning preferences is often due to their experiences. Although individuals tend to have a primary learning preference, they may choose to employ an array of learning styles based on…

Preadolescence is a critical time in the life of children because during this time individuals experience increased social pressure and make decisions that lead to lasting peer relationships (Farmer et al., 2008). Students at-risk for, or with, emotional disturbance during preadolescence struggle to adjust socially, behaviorally, and academically,…

A recent U.S. Department of Education (2009) meta-analysis concluded that blended learning may be better than either online or traditional lecture-based instruction. However, other research has shown that, for technology-enhanced instruction, learning outcomes are, at best, equal to traditional lecture-based instruction. Blended learning, when…

Many medical schools have developed computer-based, multimedia learning environments to fill the knowledge gap and provide common cases and resources to students. However, considering that multimedia in education may impede effective learning if the characteristics of learners and tasks are not considered thoroughly in instructional design, it is…

Interaction research on recasts has been largely confined to examining the effects of recasts delivered in an oral, face-to-face modality. The challenge of creating task conditions in a written interactive mode, in which the dynamism and immediacy of recasts can be brought to bear on L2 development, has been a formidable obstacle to advancing the…

The purpose of this study was to determine the relationship between using computer-assisted instruction (CAI) size and success on the Texas Assessment of Knowledge and Skills (TAKS) mathematics exam with fifth-grade students in Texas compared to the effect of alternative improvement approaches used by a control group. Research explored the use of…

The purpose of this study was to determine the effect of TI-Nspire graphing calculator use on student achievement and on teacher behavior variables of planning, teaching, and assessing. This study investigated the teaching of functions by teachers using the TI-Nspire graphing calculator versus teachers using a non-graphing scientific calculator. …
