ItemAn Examination of Undergraduate ESL Preparation(Middle Tennessee State University, 2014-2-24)Since the fall of 2004, Middle Tennessee State University (MTSU) has experienced a yearly increase in undergraduates, making MTSU the undergraduate college of Tennessee. MTSU offers a variety of different programs. While the education program teaches, addresses many factors in relation to the skills and techniques required and used in the classroom, it seems to lag in other areas- like ESL (English as a Second Language) education. ESL education is provided in schools across America to students that a have a native language other than English. Moreover, there are several education classes available at MTSU that address literacy in the classroom, practicums, and even a SPED (Special education) class that addresses the needs of special children. However, there is no program or class that addresses the needs of ESL children. So, are we truly preparing education majors for real life issues and situations in the classroom? In this action research, the researcher will interview twelve students, in different classifications, that are currently in the teacher education program. With the data retrieved, the researcher will report its findings to MTSU in hopes of creating a pilot program for ESL preparation for classrooms.
ItemThe Relationship Between Bullying and Substance Use Among Senior High School Students in Ghana, West-Africa(Middle Tennessee State University, 2014-2-25)"Introduction: School-based bullying, a global challenge, adversely contributes to psychological and physical development of adolescents. Existing evidence indicates an association between bully perpetration and substance use. Conversely, bully prevention interventions are linked to lower reports of substance use. This study examines the relationship between bullying perpetration and substance use among senior high school students in Ghana, West Africa.
Item3D PRINTING BODY PARTS: AN OVERVIEW OF HOW ADDITIVE MANUFACTURING IS SHAPING TISSUE ENGINEERING(Middle Tennessee State University, 2014-2-23)Additive manufacturing, commonly referred to as 3D printing, is a manufacturing technique that emerged in the 1980 s mainly focused on engineering prototyping. Recent advances in the precision and cost of the techniques, as well as the widespread use of 3D modeling have increased 3D printing s scope of use from high-end engineering prototypes to a large variety of uses in manufacturing. 3D printing has been shown to improve the processing time, reduce waste, and increase the level of customization of certain products by eliminating the need for the specialty tooling and dies that are traditionally used in manufacturing. Additionally, the ability to physically print complex shapes based on a computer model has given rise to new products that would otherwise be simply impossible to create. The field of tissue engineering has taken advantage of this technology by printing organic cells and inorganic biomaterials with levels of control and precision that surpass previous production techniques. Furthermore, 3D printing allows for applications that can be customized on a case-by-case basis to fit the needs of individual patients. This review will overview the 3D printing-based techniques being used in tissue engineering, and discuss the current applications and challenges of this rapidly advancing field.
ItemA preliminary analysis of GK-12 graduate fellow classroom interactions on secondary students perceptions of science(Middle Tennessee State University, 2014-2-25)"The NSF GK-12 program at MTSU partners graduate students and high school teachers with biotechnology companies to promote STEM learning opportunities. Graduate Fellows spend one year in high school biology classrooms mentoring student research projects. The purpose of the study was to determine if introducing Graduate Fellows into high school science classrooms to engage with students during the year influences the students attitudes toward science. We hypothesize that implementing programs such as GK-12 may generate a positive perception of science and increase interest in pursuing a science career.
ItemA Systematic Review of the Effect of Chromium on Fasting Blood Glucose Levels in Type 2 Diabetic Patients(Middle Tennessee State University, 2014-2-25)"Background: Although the functions of most nutrients are well known and recognized, the function of trace minerals like chromium, are not as well understood. This trace mineral has often been called the 'Glucose Tolerance Factor' due to its claimed effect of lowering blood glucose levels in type 2 diabetic patients by increasing insulin sensitivity. I conducted a systemic review to evaluate the reliability of these claims and to identify the mechanism, effect, and (possible) benefits of chromium for type 2 diabetic patients. My goal was to confirm or refute the hypothesis that chromium supplements can be used to prevent or treat type 2 diabetes.
