A literature review was conducted on E-learning situations, and a discussion on the role of visual elements in E-learning. Data collection was also conducted by way of a test, which randomly placed participants into three groups and assigned them to three different E-learning courses. The texts for the three courses were the same font, but the first course had text only, the second course had text and "bad" images, and the third one had text and "good" images. Every time participants finished a short course, they were requested to do a short quiz based on what they had learned. In addition, every participant needed to do a survey based on his or her E-learning experience. Research data was finally collected through the test scores and surveys.
Key findings of this research are: (1) The combination of text and "good" image materials in E-learning can greatly enhance the learning outcomes; (2) the "good" images in learning materials can add to the value of the text content as well as improve the satisfactory level of learners in E-learning; (3) "bad" images do not enhance E-learning outcomes; and (4) E-learners will spend a longer time to complete learning materials containing images, no matter how good or "bad" the images are.
On a daily basis I am bombarded with images in every walk of life. I encounter images crossing my path constantly through media such as the internet, television, magazines, radio, social media, even in the grocery store line on screens intended to capture our attention. As I drive down the roadways, I am invaded by images that at times can be distracting with their dazzling displays, attempting to get our attention and get us to consume their product or service or understand a historical meaning. In this dissertation I intend on looking at murals and two social studies textbooks to focus types of media; then construct an argument about how these media impact social studies curricula in the communities in which they are located taking into consideration race, social class, language, location, and culture. The intent is to critically analyze traditional curricula and curricula found in public pedagogy in communities located on the borderlands. I also asked local high school-aged students, teachers, artists, and activists from both sides of the border analyze the images through photo elicitation and traditional interviews. Students were interviewed with a focus on interpreted meanings of images presented. Teachers and artists were interviewed to discover their intended meanings as displayed through their production and circulation of intended meanings via lessons and the images they select or create. Activists were interviewed to discover local history, images, and history of the educational space where the artwork and schools are located. I used these data to create an argument as to how these forms of media impacts school curricula in the areas on both sides of the United States/Mexico border. The study was conducted in border cities El Paso, Texas and Juarez, Chihuahua. The ultimate goal was to look at how academics and curricula developers can use this information to decolonize curricula in the field of curricula studies. Moreover, this information can be used to create decolonized ideologies in curricula that can be used at the school sites to promote diversity and social justice for students in their schooling experience.
By exploring (1) language cues that orators use to signal visualization, (2) the ways in which shared cultural memories and ideas allow orators to call upon standardized images, and (3) the influence of stylistic choices and audience emotions related to the vividness of rhetorical images, I argue that it is possible to analyze the ways in which classical Greek orators understood and employed visual elements in their rhetorical performances. I then conduct an analysis of the visual aspects of Demosthenes' On the Embassy using these heuristics to demonstrate the ways in which these three aspects of visuality are intertwined and contribute to a greater understanding of the relationship between the verbal and the visual in rhetorical theory.
My findings indicate that Greek orators readily identified the influence of visual ways of knowing on rhetorical theory and presented early hypotheses of the ways in which sense perceptions affect social practice. This project complicates the ways in which rhetorical theory is categorized. Rather than considering visual rhetoric as a distinct field from traditional, verbal text-based rhetorical studies, this project explores the ways in which visual and verbal modes of thinking are interconnected in Greek rhetorical theory. By bridging these two areas of rhetorical study and arguing that verbal rhetoric can instantiate internalized, visual phenomena for audiences, the dichotomy of verbal and visual is problematized. By focusing on the rhetorical theory of classical Greece, this project also invites future research into the ways in which dominant, Western historic and contemporary systems of epistemology are influenced by the co-mingling of verbal and visual in classical Greek philosophy and education.
The majority of trust research has focused on the benefits trust can have for individual actors, institutions, and organizations. This “optimistic bias” is particularly evident in work focused on institutional trust, where concepts such as procedural justice, shared values, and moral responsibility have gained prominence. But trust in institutions may not be exclusively good. We reveal implications for the “dark side” of institutional trust by reviewing relevant theories and empirical research that can contribute to a more holistic understanding. We frame our discussion by suggesting there may be a “Goldilocks principle” of institutional trust, where trust that is too low (typically the focus) or too high (not usually considered by trust researchers) may be problematic. The chapter focuses on the issue of too-high trust and processes through which such too-high trust might emerge. Specifically, excessive trust might result from external, internal, and intersecting external-internal processes. External processes refer to the actions institutions take that affect public trust, while internal processes refer to intrapersonal factors affecting a trustor’s level of trust. We describe how the beneficial psychological and behavioral outcomes of trust can be mitigated or circumvented through these processes and highlight the implications of a “darkest” side of trust when they intersect. We draw upon research on organizations and legal, governmental, and political systems to demonstrate the dark side of trust in different contexts. The conclusion outlines directions for future research and encourages researchers to consider the ethical nuances of studying how to increase institutional trust.
Invasive species are non-native plants or animals that harm the environment, economy, and even human health. These species are introduced to new environments where they have no natural predators or competitors to keep them in check. As a result, they grow and reproduce quickly, outcompeting and displacing native species. Invasive species can also damage crops, infrastructure, and property, leading to significant economic losses. Moreover, some invasive species can carry diseases that can affect human health. As the leading cause of biodiversity loss according to the IUCN Red List, controlling and preventing the spread of invasive species is critical to protecting biodiversity and maintaining a healthy environment.
