Academics such as Geneva Gay, Christine Sleeter, Samy Alim, and Django Paris have conducted research that illustrates the importance of educators being not only aware of the culture of their students but implementing curriculum that supports the diverse cultures of their students. A common finding among this research is that a culturally sustaining pedagogy is essential to the inclusion of all students in the classroom and the level of academic success they have in schools.

Show moreAcademics such as Geneva Gay, Christine Sleeter, Samy Alim, and Django Paris have conducted research that illustrates the importance of educators being not only aware of the culture of their students but implementing curriculum that supports the diverse cultures of their students. A common finding among this research is that a culturally sustaining pedagogy is essential to the inclusion of all students in the classroom and the level of academic success they have in schools. This study aims to investigate the effect of teacher beliefs on the academic performance of Latinx students and on the culture and atmosphere of the school. The purpose of conducting this research is to show the necessity for implementing a culturally sustaining pedagogy and curriculum in schools. My research requires teachers and administrators to answer survey questions concerning their teaching practice, student population, and beliefs about teaching students, specifically Latinx students. I hope to discover how teacher attitudes, both positive and negative, can affect the academic performance of Latinx student and the culture of the school. Lastly, with such an emphasis I would like to use this information to help educators embrace the differences of their students and see the value in incorporating students lived experiences in the class curriculum. Using a survey modeled after Bandura's Survey for Teaching Self-Efficacy this thesis explores the following questions: Research Question One (RQ1): What effect does teachers' attitudes have on the culture of their school?, Research Question Two (RQ2): What effect does teachers' socio-political views have on Latinx student performance?

The purpose of this research was to look more closely at the relationships between narrative and non-narrative persuasive messages, and to begin to determine how and why these message formats might work together. I situated this study within Rogers' roadmap for future theoretical work on entertainment education (E-E), and specifically addressed Slater and Rouner's call for more research on the impact of epilogues in E-E.

Show moreThe purpose of this research was to look more closely at the relationships between narrative and non-narrative persuasive messages, and to begin to determine how and why these message formats might work together. I situated this study within Rogers' roadmap for future theoretical work on entertainment education (E-E), and specifically addressed Slater and Rouner's call for more research on the impact of epilogues in E-E. Synthesizing components of the elaboration likelihood model with recent theorizing regarding persuasion through narrative, I made predictions regarding the effect of transportation and character identification on perceived salience, attitudes, behavioral intention, and behavior in narrative, argument, and narrative + argument conditions. Undergraduate students were asked to watch one of seven videos. After watching the videos participants were asked to respond to questions reflecting their views of the subject matter in the videos, their experience while watching the videos, and their opinion of the video quality. The questionnaire included scales measuring transportation into the narrative and character development, measures of perceived issue relevance, and persuasion toward the topic of mandatory H1N1 vaccinations. Findings showed no relationship between the narrative format and transportation or perceived salience, however, transportation did predict perceived salience in messages combining both argument and narrative + argument formats. Recommendations were made for modification and future applications of the instruments used in the study and for continued research in the various stages of persuasion through narrative, argumentative, and combined format messaging.

Reeves, De'Siree, Chin, Matthew, University of Central Florida
- Abstract / Description
-
The objective of this thesis was to investigate intersectional (categorical/social) invisibility and the extent to which this phenomenon occurs in a comparison of dominant (i.e., Caucasian), and non-dominant (African-American and Latino) social/ethnic groups. It has been found that intersectional invisibility occurs among African-American women with respect to Caucasian men and women, and African American men (Sesko & Biernat, 2010), but little of this research has been done regarding Latinas...
Show moreThe objective of this thesis was to investigate intersectional (categorical/social) invisibility and the extent to which this phenomenon occurs in a comparison of dominant (i.e., Caucasian), and non-dominant (African-American and Latino) social/ethnic groups. It has been found that intersectional invisibility occurs among African-American women with respect to Caucasian men and women, and African American men (Sesko & Biernat, 2010), but little of this research has been done regarding Latinas. Thus, this experiment aims to not only examine whether Latinas are also subject to intersectional invisibility among dominant (i.e., Caucasian) and non-dominant (i.e., African American and/or Latino) groups, but to determine whether the theory can be extended to perceptions between non-dominant groups such as African-Americans and Latinos. Determining whether intersectional invisibility occurs among Latinas, moreover, may provide theoretical and practical insights of what advantages/disadvantages Latinas may particularly endure as members of the rapidly growing Latino population in the U.S.

In content-based image retrieval (CBIR) systems, there are two general types of search: target search and category search. Unlike queries in traditional database systems, users in most cases cannot specify an ideal query to retrieve the desired results for either target search or category search in multimedia database systems, and have to rely on iterative feedback to refine their query.

Show moreIn content-based image retrieval (CBIR) systems, there are two general types of search: target search and category search. Unlike queries in traditional database systems, users in most cases cannot specify an ideal query to retrieve the desired results for either target search or category search in multimedia database systems, and have to rely on iterative feedback to refine their query. Efficient evaluation of such iterative queries can be a challenge, especially when the multimedia database contains a large number of entries, and the search needs many iterations, and when the underlying distance measure is computationally expensive. The overall processing costs, including CPU and disk I/O, are further emphasized if there are numerous concurrent accesses. To address these limitations involved in relevance feedback processing, we propose a generic framework, including a query model, index structures, and query optimization techniques. Specifically, this thesis has five main contributions as follows. The first contribution is an efficient target search technique. We propose four target search methods: naive random scan (NRS), local neighboring movement (LNM), neighboring divide-and-conquer (NDC), and global divide-and-conquer (GDC) methods. All these methods are built around a common strategy: they do not retrieve checked images (i.e., shrink the search space). Furthermore, NDC and GDC exploit Voronoi diagrams to aggressively prune the search space and move towards target images. We theoretically and experimentally prove that the convergence speeds of GDC and NDC are much faster than those of NRS and recent methods. The second contribution is a method to reduce the number of expensive distance computation when answering k-NN queries with non-metric distance measures. We propose an efficient distance mapping function that transfers non-metric measures into metric, and still preserves the original distance orderings. Then existing metric index structures (e.g., M-tree) can be used to reduce the computational cost by exploiting the triangular inequality property. The third contribution is an incremental query processing technique for Support Vector Machines (SVMs). SVMs have been widely used in multimedia retrieval to learn a concept in order to find the best matches. SVMs, however, suffer from the scalability problem associated with larger database sizes. To address this limitation, we propose an efficient query evaluation technique by employing incremental update. The proposed technique also takes advantage of a tuned index structure to efficiently prune irrelevant data. As a result, only a small portion of the data set needs to be accessed for query processing. This index structure also provides an inexpensive means to process the set of candidates to evaluate the final query result. This technique can work with different kernel functions and kernel parameters. The fourth contribution is a method to avoid local optimum traps. Existing CBIR systems, designed around query refinement based on relevance feedback, suffer from local optimum traps that may severely impair the overall retrieval performance. We therefore propose a simulated annealing-based approach to address this important issue. When a stuck-at-a-local-optimum occurs, we employ a neighborhood search technique (i.e., simulated annealing) to continue the search for additional matching images, thus escaping from the local optimum. We also propose an index structure to speed up such neighborhood search. Finally, the fifth contribution is a generic framework to support concurrent accesses. We develop new storage and query processing techniques to exploit sequential access and leverage inter-query concurrency to share computation. Our experimental results, based on the Corel dataset, indicate that the proposed optimization can significantly reduce average response time while achieving better precision and recall, and is scalable to support a large user community. This latter performance characteristic is largely neglected in existing systems making them less suitable for large-scale deployment. With the growing interest in Internet-scale image search applications, our framework offers an effective solution to the scalability problem.

Show moreThis collective case study explores the nature of the relationship between teachers' use of culturally responsive teaching (CRT) practices and students' engagement in constructing viable arguments and critiquing the reasoning of others (SMP3). This study was informed by the Common Core State Standards Initiative related to developing mathematically proficient students through the use of student engagement practices consistent with the standards for mathematical practice. As a means to support teachers' facilitating specific student engagement practices, professional development was provided. This study is situated in the growing body of research associated with student engagement and cultural identity. The case of two teachers was defined from interviews, classroom observations, journal prompts, and student artifacts. Data was collected before, during, and after professional development following a cross-case analysis. Four themes emerged: (a) shift in teacher practice; (b) depth and breadth of the knowledge of culturally responsive teaching and standard for mathematical practice three; (c) teacher reflection and reception; and (d) classroom management. The findings suggest that the shift in teacher practice can be supported by professional development focused on reflective practice. This shift is impacted by classroom management and teachers' depth and breadth of their knowledge of CRT and SMP3.
