Title: THE DOCTRINE OF SELF-DETERMINATION.
Creator: Moskovits , Kelsey, Kiel, Dwight, University of Central Florida
Abstract / Description: Poverty and underdevelopment plague millions of people in the world today. Interestingly, the 800 million people that are currently living on less than a dollar a day correlate very closely with the 750 million people who were under colonial subjugation in 1945. In an effort to understand how the disparities in development came about, the theory of self-determination will be defined and historically assessed. Through qualitative evaluation of the principle and history of self-determination...
Show morePoverty and underdevelopment plague millions of people in the world today. Interestingly, the 800 million people that are currently living on less than a dollar a day correlate very closely with the 750 million people who were under colonial subjugation in 1945. In an effort to understand how the disparities in development came about, the theory of self-determination will be defined and historically assessed. Through qualitative evaluation of the principle and history of self-determination and case studies on three key regions that have never known genuine self-rule, it will become clear that the doctrine of self-determination only ever existed in rhetoric. Resource trap theory will be applied to those who have been plagued by outside rule and a general assessment of the state of self-determination in the world will be given. Lastly, an argument for what right transcendently will be given based on the current state of affairs and on Kantian ethics.

Show moreThe idea that free will may be an illusion has been a source of great concern. It has led to suggestions that it may be wise to avoid public discussion of this topic lest it lead to a general moral decay. This concern has seemingly been supported by research demonstrating that individuals, when primed with the notion they lack free will, tend to cheat more and prefer less retributive punishment. The current research suggests that these effects can be moderated by the introduction of a second prime. In experiment one, participants believed they were being tested on note-taking and the subsequent recall of the content of two articles when, in fact, the dependent measure was actually the degree to which, after being primed with the articles, they cheated on a math task. It was hypothesized that the cheating effect noted in prior research would be moderated by the introduction of a second prime � one that extends the concept of self beyond our dualistic intuitions. In a second experiment, it was hypothesized that this prime would also moderate the reported reduction of preference toward retributivist punishment. In each experiment, the results trended in the direction hypothesized but in neither case were they statistically significant. The difficulties surrounding methodology and reproducibility in this type of research is discussed and suggestions for improvements in experiment design are offered.

Show moreThe purpose of this study was to examine the motivation of individuals to use Truly Accomplished (TA) as a fitness intervention, with or without a social support component. All participants utilized the TA Software as a fitness intervention and received weekly feedback on their progress. Thirty participants were randomly assigned to either participate in the regular TA process or a modified TA process with the addition of a social support component in the form of a social media group. Participants in the modified condition posted weekly to a Facebook group page about successes and obstacles they faced and gave feedback to their peers. It was hypothesized that participants, regardless of condition, would show fitness gains in the 6-week study. Also, with the added social support component to TA, participants were expected to have higher levels of self-determination in relation to the three psychological needs (i.e. autonomy, relatedness, and competence) and higher levels of perceived social support. A between-subjects deign was used to measure overall effectiveness, changes in fitness performance (plank, push-ups, wall-sit, step-test) and body composition (BMI, percent body fat), perceived social support, levels of psychological needs satisfaction as it relates to the three basic needs (autonomy, competence, and relatedness), and satisfaction with TA. No significant differences were found between conditions for satisfaction with TA, levels of perceived social support, or levels of psychological needs satisfaction post-intervention. However, a significant increase was found regardless of condition in terms of autonomy and guidance. A significant increase was shown in both the plank and modified push-up post-intervention measure, regardless of condition. Finally, the condition with the added social support had a significantly higher overall effectiveness gain than the condition with no added social support. The practical and theoretical implications of the results are discussed.

Show moreWith the passage of the No Child Left Behind Act, schools and school districts have come under increased pressure to demonstrate student proficiency and success at the elementary, middle and high school levels. Each state is required to use standardized test data as evidence of student proficiency. The data is collected by each state and reported to the federal government to demonstrate progress. In Florida, the exam used to record proficiency is the Florida Comprehensive Assessment Test (FCAT). At all three levels, the FCAT is administered annually and the results are used to create school grades ranging from A-F. Florida high schools fall in the lowest 10% in the nation for graduation rates, graduating less than 60% of high school students. The pressure created by these high stakes tests have led to a growth in Florida secondary schools implementing the Advancement Via Individual Determination (AVID) program. AVID seeks to offer a rigorous curriculum with additional support to underserved students. However, some literature demonstrates that schools with AVID improve the success of not only AVID students, but the overall population as well. This is commonly referred to as the "AVIDization" of a school. This study used an independent t-test to compare middle schools in eleven Florida county school districts with AVID to non-AVID schools in the 2007-2008 school year in six main areas; a) FCAT Math scores, b) FCAT Reading scores, C) overall FCAT scores, d) frequency of disciplinary incidences, e) attendance rates, and f) overall FCAT scores with controlled data. In this study, 85 middle schools had AVID and 179 middle schools were non-AVID. In comparing AVID to non-AVID students in the six areas, the t-test demonstrated that schools with the AVID program did not outperform non-AVID schools in the three FCAT tested areas. Also, the data shows that AVID schools were more likely to have higher reported rates of disciplinary incidences then non-AVID schools.

Show moreThis study explored the efficacy of using a virtual college campus to teach self-determination skills to middle school students with learning disabilities. Teaching self-determination skills is considered best practice for students with disabilities as they transition into adulthood. Three measures, a self-determination knowledge measurement scale, a behavior rubric, and 15 multiple choice questions measured self-determination knowledge and skill application ability with 71 middle school students with learning disabilities. The measures were used to determine whether the students who learned about self-determination skills in the virtual college setting during one training session displayed more knowledge and application of these skills than students who learned about and applied these skills in the natural setting. Empirical data revealed that overall, students made significant gains in their capacity to be self-determined in both natural and virtual settings. Students who participated in self-determination skills training in the virtual college setting displayed significantly more self-determination skills knowledge than the two control groups. Anecdotal evidence suggested that the students who learned in the virtual learning environment were also able to generalize these skills to both home and school settings after only one training session. Recommendations were made for future studies utilizing virtual learning environments to teach students with disabilities self-determination skills and increasing the use of digital media in teacher preparation programs.

Show moreEctotherms (including marine turtles) being especially sensitive to climate, are at risk to the accelerated rate of human-driven climate change. This study addresses two concerns associated with marine turtles and climate change (-) the relationship between the timing of marine turtle nesting and sea surface temperature; and the concern over the feminization of marine turtle populations due to rising sand temperatures. Previous studies of loggerhead sea turtles (Caretta caretta) and green sea turtles (Chelonia mydas) have documented the relationship between sea surface temperatures and nesting phenology. Earlier nesting behaviors in both species have been associated with warmer sea surface temperatures. Also, sex determination for marine turtles is temperature-dependent. Due to current sand temperatures, it is estimated that loggerhead (Caretta caretta) nests along the Atlantic coast of Florida already produce over 89% female hatchlings. Using shade to reduce nest temperature and increase the proportion of male hatchlings is one option for mitigating the impacts of climate change on marine turtle sex ratios. In this study, a 21-year (1988-2008) dataset of hawksbill sea turtle (Eretmochelys imbricata) nesting at Buck Island Reef National Monument, St. Croix, USVI was analyzed in a similar manner to previous studies. It was found that warmer sea surface temperatures were associated with longer nesting seasons and later median nesting dates. Additionally, a preliminary sand shading study was conducted in the first field season (2011) with a subsequent loggerhead nest shading study in the following field season (2012). Although hatching success was not significantly impacted, temperatures were significantly reduced in the majority of shaded nests. This practice may not be immediately applicable as a means of managing sex ratios, but it could be used to reverse the temperature effects of nest relocation.

Show moreIndividuals, who work in high risk confrontational (HRC) settings in which a conflict exists, experience high-stress levels in their jobs and are known to have a high level of decreased performance and decreased survival. Individuals being trained to handle such conflicts should be trained effectively to accomplish the ultimate objective, staying alive. The problem is the lack of research and program evaluations examining effectiveness of training simulations in the transfer of skills under HRC settings. The purpose of my study was to test if the skill of target acquisition could be effectively transferred to a real environment (RE) after exposure within a virtual environment (VE). Ackerman's (1988) Theory of Ability Determinants of Skill Acquisition supports the progression participants advance through in the transfer of learning. A randomized posttest only comparison group design was used. The population involved 24 novice paintball players. Participants were randomly assigned to a simulation treatment or a non-simulation comparison application. Two days after receiving the intervention, participants engaged in live practice sessions (game 1 and game 2) in a RE where target acquisition skills were measured. Evidence suggests significant differences were found between novice players in the type of intervention received and the number of targets acquired in a RE, whereas, no significant change in scores was found between practice sessions, and no interaction was found between intervention received and practice. Recommendations for replicating studies include: (a) focusing on the manipulation of specific variables within the training context, (b) using different live environments, (c) examining factors that influence teaming and strategy formation, and (d) combining experts and novice players for a closer representation of a population in an HRC setting.

Show moreThere is a certain tradition, pageantry, rivalry, and glory in college football. It is well known that college football can be a big time money maker and sometimes covers the costs of other athletic teams within a school. However, it is also recognized that many college football programs lose money or struggle to break even. Thus, there is tremendous variability that exists in the amount of resources a school may have and the outcomes in athletic success, while there is not always a one to one correspondence between the two. The purpose of this study is to examine and analyze the quantifiable determinants of success, considering both financial and non-financial variables. The pressure to win, and do so immediately; brand; and outdo other schools in the facility "arm's race" has reached unprecedented levels.

Show moreThe political focus of equitable health outcomes in the United States have long centered on access to medical care. However, there is compelling evidence that access to medical care is only the bare minimum necessary to achieve health, and the true influence of health insurance on health is still unclear. Widely accepted models of health estimate that less than 20% of health outcomes can be attributed to clinical care, while greater than 50% is related to social and economic determinants of health, with income being the most consistent predictor. As a result, this study investigated whether earned income is related to insurance status on the one hand and self-rated health on the other; whether the association between income and self-rated health is indirectly influenced by the presence of health insurance (-)namely private health insurance; whether there are differences in self-rated health between the privately insured, the publicly insured, and the uninsured; and if duration of uninsurance was inversely associated with self-rated health. As hypothesized, higher income was associated with having health insurance, and in particular private insurance. Among all included predictor variables, higher income and private insurance are the strongest predictors of higher self-rated health, and lower income and Medicaid were the strongest predictors of lower self-rated health. This study affirms that the health of persons with Medicaid is more similar to persons who are uninsured, and the health of persons with private insurance is more similar to those with Medicare. The association between income and self-rated health is indirectly influenced by health insurance. Age and education exerted the strongest overall influence on self-rated health: older respondents had lower self-rated health, and more educated respondents had higher self-rated health. And as uninsurance duration increased, self-rated health decreased. Additional studies are recommended to improve health insurance policy.

More specifically, this study was conducted to determine if there was a mean difference in student performance on the Florida Comprehensive Assessment Test (FCAT) in mathematics, reading, and writing between students who participated in the AVID program during their first two years of high school and students who had similar demographics (e.g., ethnicity, gender, and economic status) but did not participate in the AVID program for 2007-2009. The population for this study consisted of students from six high schools with certified AVID programs during the 2007-2008 and 2008-2009 school years in two central Florida school districts. Students participating in the AVID program were matched with non-AVID participants for each school site by ethnicity, gender, socioeconomic status, and tenth grade mathematics or English course. The results of this study did not indicate statistically significant differences in the FCAT mathematics and reading developmental scale score gains between the AVID and non-AVID students. However, the non-AVID students performed significantly higher on the tenth grade writing component of the FCAT. Participation in the AVID program produced no statistically significant findings for the factors of gender, ethnicity, and socioeconomic status for FCAT mathematics, reading, or writing. The findings indicated that AVID and non-AVID students could not be differentiated by FCAT performance measures in the mathematics and reading domains.

Show moreBiochemical research and clinical studies have revolutionized the field of medicine in both diagnosis and therapy. Researchers in the field of biochemistry and biotechnology are using nanomaterials in different applications to develop devices and materials that offer benefits to both patients and the health care industry. These include biochemical sensors, enzyme encapsulation, biomarkers, and drug delivery improvements for the treatment of cancer. This dissertation focuses on investigating two biochemical aspects using nanomaterials; namely therapy and clinical diagnosis.For therapy purposes, Silica nanoparticles were used as drug delivery system to develop a new photodynamic cancer therapy agent photo-acid generator (PAG) that selectively induces necrotic cell death of cancer cells. The developed PAG is oxygen-independent and - when excited at specific wavelengths - drops the pH within the lysosome of cancer cells to produce apoptosis/necrosis. It was specifically designed for in vivo applications and conjugated with synthesized, highly monodispersed silica nanoparticles (Si NPs) functionalized with amine groups via amid links (SiN-NH-PAG). Additional Features include high photo-acid quantum yield, high one-photon (1PA) and two-photon absorption (2PA) with low fluorescence quantum yield. In vivo, confocal microscope studies with HCT-116 (Human colorectal carcinoma) cancer cells showed that photodynamic processes in the presence of PAG were completed under one- photon absorption (1PA) conditions. In these experiments, cells were imaged at 1 min intervals for a total of 4 hours with the aid of Differential Interference Contrast (DIC). Among the photodynamic therapy agents tested via cytotoxicity experiments with the MTS assay, (SiN-NH- PAG) showed the best efficiency to induce cell death. The increased effectiveness of the new agent is probably due to the large number of PAG groups present on the surface of Si NPs.iiLysosome colocalization indicates that PAGs are mainly built in lysosomes. The increase of acidic content inside the lysosome was demonstrated with the aid of the LysoSensor Green probe. The drop in the intralysosomal pH was approximately 0.3 units. This is a desirable outcome as most cells underwent necrosis at pH ? 4.4. For clinical diagnosis purposes, a biochemical sensor was developed for the analysis of phosphate ions in urine samples. Abnormal levels of inorganic phosphate in human urine samples are related to the development of certain types of cancers affecting several organs of the human body, including breast, pancreas, lung and thyroid. The new biochemical sensor is based on the fluorescence energy transfer between a lanthanide luminescent probe [Tb-EDTA]-1 and gold nanoparticles (Au NPs) capped with a Cetyltrimethylammonium bromide (CTAB) micelle. With this approach, it was possible to selectively determine inorganic phosphate (Pi) in urine samples at the micro-molar concentration level. Urine samples collected from healthy, non-smoking individuals showed no interference from concomitants usually found in human urine samples. The simplicity of analysis provides an approach well-suited for (")real-time(") monitoring of phosphate ions. Analysis time is made possible within approximately 10 min per sample.

Show moreCurrent trends in spacecraft are leading to smaller, more inexpensive options whenever possible. This shift has been primarily pursued for the opportunity to open a new frontier for technologies with a small financial obligation. Limited power, processing, pointing, and communication capabilities are all common issues which must be considered when miniaturizing systems and implementing low-cost components. This thesis addresses some of these concerns by applying two methods, in attitude estimation and control. Additionally, these methods are not restricted to only small, inexpensive satellites, but offer a benefit to large-scale spacecraft as well.First, star cameras are examined for the tendency to generate streaked star images during maneuvers. This issue also comes into play when pointing capabilities and camera hardware quality are low, as is often the case in small, budget-constrained spacecraft. When pointing capabilities are low, small residual velocities can cause movement of the stars in the focal plane during an exposure, causing them to streak across the image. Additionally, if the camera quality is low, longer exposures may be required to gather sufficient light from a star, further contributing to streaking. Rather than improving the pointing or hardware directly, an algorithm is presented to retrieve and utilize the endpoints of streaked stars to provide feedback where traditional methods do not. This allows precise attitude and angular rate estimates to be derived from an image which, with traditional methods, would return large attitude and rate error. Simulation results are presented which demonstrate endpoint error of approximately half a pixel and rate estimates within 2% of the true angular velocity. Three methods are also considered to remove overlapping star streaks and resident space objects from images to improve performance of both attitude and rate estimates. Results from a large-scale Monte Carlo simulation are presented in order to characterize the performance of the method.Additionally, a rapid optimal attitude guidance method is experimentally validated in a ground-based, pico-scale satellite test bed. Fast slewing performance is demonstrated for an incremental step maneuver with low average power consumption. Though the focus of this thesis is primarily on increasing the capabilities of small, inexpensive spacecraft, the methods discussed have the potential to increase the capabilities of current and future large-scale missions as well.

Show moreIt is now a matter of routine for the forensic scientist to obtain the genetic profile of an individual from DNA recovered from a biological stain deposited at a crime scene. Potential contributors of the stain must either be known to investigators (i.e. a developed suspect) or the questioned profile must be searched against a database of DNA profiles such as those maintained in the CODIS National DNA database. However, in those instances where there is no developed suspect and no match is obtained after interrogation of appropriate DNA databases, the DNA profile per se presently provides no meaningful information to investigators, with the notable exception of gender determination. In these situations it would be advantageous to the investigation, if additional probative information could be obtained from the biological stain. A useful biometric that could provide important probative information, and one that may be amenable to molecular genetic analysis, is the biological age of an individual. The ability to provide investigators with information as to whether a DNA donor is a newborn, infant, toddler, child, adolescent, adult, middle-aged or elderly individual could be useful in certain cases, particularly those involving young children such as kidnappings or in providing additional intelligence during terrorist investigations. Currently no validated molecular assays exist for age determination. Biological human ageing can be defined by two distinct processes, degenerative and developmental ageing. The degenerative process of ageing is based on theories which identify an increase or decrease in physiological conditions with increasing age. In contrast, the developmental process of ageing is based on the theory that as individuals increase in chronological age, there will be subtle corresponding molecular based biological changes, each requiring genes to be expressed or silenced, indicative of that particular stage of life. We investigated the degenerative process of chromosomal telomere shortening, as well as the developmental process of gene expression profiling analysis, in an attempt to identify biomarkers of biological age in a self-renewing tissue such as blood. While telomere length analysis was an ineffective method for age determination; gene expression analysis revealed three gene transcripts expressed in an age-dependent physiological manner. These species namely- COL1A2, HBE1 and IGFBP3, were found to be expressed at elevated levels in younger individuals, newborns, or post-pubertal individuals, respectively. The biological process of hemoglobin switching was also investigated for the possibility of determining human age. While experimenting with the potential of using the gamma-hemoglobin chains, as newborn specific gene candidates, we serendipitously discovered four novel truncated transcripts, which we have termed HBG1n1, HBG1n2, HBG2n2 and HBG2n3; whose expression was restricted to whole-blood newborn samples and specific fetal tissues. The molecular origin of these transcripts appears to be at the RNA level, being produced by specific rearrangement events occurring in the standard gamma hemoglobin transcripts (HBG1 and HBG2), which yield these new isoforms that are expressed in a highly regulated tissue specific manner.

Show moreTelehealth and telemedicine have revolutionized the healthcare system in terms of access to information and remote medical treatment. While there is a great deal of literature on current perceptions of telehealth care systems, relatively little is known about perceived user needs and acceptance of future telehealth systems. One way to assess future attitudes is to evaluate anticipated usage of telehealth devices through perceived advantages and disadvantages. Additionally, this study seeks to assess the reliability of a new measure of technology acceptance that capitalizes on human motivation using self-determination theory. An online survey consisted of an original 40-item measure of motivation to use telehealth technology, the Psychosocial Impact of Assistive Devices Scale (PIADS; Jutai & Day, 1996), questions adapted from Edwards et al. (2014) about perceived advantages and disadvantages of telehealth devices, and open-ended questions about advantages, disadvantages, and concerns of interacting with telehealth devices in the future. The open-ended questions were coded for themes. Results also indicated that there was a high reliability between the MUTT and the PIADS, however the MUTT was slightly more reliable. Significant correlations were found between the overall MUTT and subscales of autonomy, competence, relatedness, and goals, as well as moderate correlations between the subscales of the PIADS (i.e., competence, adaptability, self-esteem) and the MUTT. The results of this research will be discussed further.

Elementary school teachers (N=574) from 27 schools in suburban Seminole County, Florida completed the School Culture Triage Survey to generate a school culture score. The participating schools were ranked and placed in categories representing the top 33% (N=9), middle 33% (N=9), and bottom 33% (N=9) of the population based on their culture score. School culture data were analyzed and correlated with third grade student achievement data, as measured by the 2007 Florida Comprehensive Assessment Test (FCAT) Reading to determine if there were any relationships between (a) school culture and student achievement; (b) the three key components of school culture (collaboration, collegiality, and self-determination/efficacy) and student achievement; and (c) principal tenure and school culture. Additional data analysis served to determine if there were any experiential or demographic differences among the teachers from the schools falling in the top, middle, and bottom 33% on the School Culture Triage Survey. To learn more about principal beliefs with regard to school culture and student achievement, principal interviews were conducted with some principals (N=8) from the participating schools. Through a review of the research results and related literature, the researcher concluded that a relationship between the overall school culture and student achievement did not exist. Further analysis revealed that there were no relationships between student achievement and collaboration, collegiality, and self-determination/efficacy, or between school culture and principal tenure for the schools participating in this study.

Show morePoor dietary choices and lack of physical activity are two main contributing factors for the increasing prevalence of overweight and obesity in the United States. Overweight and obese individuals are at risk for developing major life-threatening diseases. Weight loss is an effective means for reversing these adverse health effects, and smartphone applications (apps) may be an effective means for supporting weight loss outside of formal clinical settings. This study involved identifying factors that contribute to effective weight loss to compare with functionality commonly found in a sample of calorie counter apps. A content analysis was performed using a design framework that included a conceptual model describing the interaction of behaviors for effective weight loss and functional design requirements based upon behavior change and motivation to achieve weight loss. The requirements were used to analyze the presence of features in a sample of popular calorie counting apps, to infer their capability in supporting users' motivation to achieve weight loss. Results indicated that app features might not provide sufficient support to facilitate effective weight loss. Lack of supportive features affects perceived autonomy, relatedness, and competence, reducing motivation. This study provided guidelines to improve the design of calorie counter apps to include more features that support users as they engage in weight loss behaviors. The guidelines may become practical for use in mHealth apps used as part of formal and informal weight management strategies. Implications for future research involving wearable technologies and the use of gamified design strategies are discussed.

Show moreThe goal of this research was to investigate teachers' perceptions of professional discretion and satisfaction related to internal and external factors of curriculum control. Results of the study were intended to provide data to policy makers and school district administrators that could be used in the development and implementation of the curriculum reform process. Middle and high school teachers in a large central Florida school district completed the survey. The survey's six constructs were 1. Influence of Teacher Beliefs 2. Perceptions of Success and Satisfaction 3. Influence of Tests and Curriculum Guides 4. Teacher Control of Pedagogy 5. Leadership 6. Maintaining High Standards The research questions focused on determining the difference in perspectives due to years of teaching experience, level of teaching (middle or high school), and curriculum control category (high, medium, or low). The results revealed there was not significant disagreement among teacher perceptions based on years of teaching experience. However, results indicated significant differences in perceptions based on level of teaching and curriculum control category in regard to the six survey constructs. The construct of leadership revealed significant differences between both levels of teaching and curriculum control categories. Overall, the results indicated a significant relationship among curriculum control policies and effects on teachers' perceptions of professional discretion and satisfaction. The literature on curriculum reform efforts since the 1980s, specifically in the areas of curriculum standards, textbook adoption policies, testing policies and leadership practices, framed the study. The literature review focused on existing research issues within the six constructs and the research questions. The information gained from this study may be used to inform policies, improve teachers' working conditions, and promote teacher and leadership effectiveness. Recommendations for practice were addressed in terms of what policy makers, school district administrators, and individual classroom teachers can and should do to implement and support meaningful curriculum reform. The researcher emphasized that recognizing the professional expertise and knowing the perspective of teachers are key to the development and implementation of an effective curriculum reform process.

Show moreThe use of online courses continues to increase despite the small amount of research that exists on the effectiveness of online educational environments. The little research that has been conducted has focused on evaluating factors taken into consideration during the adoption of online learning environments. One notable benefit often cited is the ability to incorporate multimedia such as video games. Although game researchers and developers are pushing for the use of video games for educational purposes, there is a lack of research on the effectiveness of serious video games. When paring the increasing use of online educational environments, the push to use serious video games, and the lack of research on the effectiveness of online learning environments and video games, there is a clear need for further investigation into the use of serious video games in an online format. Based on current literature, no other known study has conducted an analysis comparing a serious game-based and non-game based online course; making this a unique study. The purpose of this study was to compare student learning experiences and outcomes between a serious game-based and non-game based online American History course. The data sources were data provided from Florida Virtual School (FLVS) and student and teacher interviews. Random samples of 92 students were statistically analyzed. A group of 8 students and 4 teachers were interviewed. FLVS data provided were analyzed using an independent t-test and the Mann-Whitney test and the student and teacher interview were analyzed using thematic analysis. Results of an independent t-test revealed that there was a significant (p < .01) difference in the mean number of days necessary to complete the course (MGB = 145.80, SDGB = 50.64, MNGB = 112.63, SDNGB = 49.60). The Mann-Whitney results indicated a significant difference between course performance and the type of American history course (Z = -5.066, p < .01); students in the serious game-based online course had an A average whereas students in the non-game-based online course had a B average. The thematic analysis of the relationship between student performance and motivation in both courses indicated that students and teachers of the game-based online course provided more reasons for student motivation than the students and teachers in the non-game-based online course. The thematic analysis of what aspects do students perceive as helpful and/or hindering to their learning indicated that students and teachers of the game-based online course provided more desirable, more helpful, less undesirable, and less hindering aspects for their course than the students and teachers in the non-game-based online course. As a result of the unique nature of this study, the findings provide new information for the fields of research on online learning, serious video gaming, and instructional design as well as inform instructional-designers, teachers, education stakeholders, serious video game designers, and education researchers.
