This qualitative research study explores the use of television as text in adult literacy as a means of bridging orality and literacy. The reason for selecting television as an educational tool was to provide equal access to stories for both non-readers and readers of print, and the 22 research participants were required to complete a survey and participate in four 2-hour workshops, and a taped interview. During the workshops, participants learned to actively engage with the texts that were edited stories from the Canadian television series North of 60. The researcher included reading strategies to encourage the participants' interaction with the texts as active "readers" (see Fiske, 1987; Buckingham, 1993; Bianculli, 1992) and brainstorming to increase their vocabulary prior to writing reflective responses. First, how television as text influences an adult literacy student's ability to transfer information from oral texts into print texts is analyzed. The findings indicate that television allows non-readers, reluctant readers, and delayed readers of English to learn literary terms and conventions that apply to print stories and practise four domains of language acquisition - listening, speaking, reading, and writing. A selection of each participant's written responses to the stories and interview fragments have been analyzed. Whenever possible, the selection is based on a participant's favorite story or personal connection to a character. Second, the effect of brainstorming on written responses has been examined. This technique is a pre-writing strategy the researcher used not only to assist the participants in recording vocabulary relevant to the story, but also to provide opportunities for sharing ideas in the construction of meaning. Based on data collected during the interviews, individuals with short-term memory problems indicate that repetition of vocabulary through brainstorming, note-taking, and discussion reinforces memory retention, and second language learners gain knowledge of pronunciation by hearing and rehearsing vocabulary from the stories. Third, factors contributing to the participants' reflective oral and written responses to the television stories have been analyzed. The main factors contributing to reflective thinking and writing involve the research pedagogy and the development of reflective skills through practice. The researcher's reflective methodology combines phenomenology, critical ethnography, and emancipatory practice from the diverse perspectives of van Manen (1990), Haig- Brown and Archibald (1996), and Freire (1974,1994,1997,1998) who have informed this study together with other researchers in the respective fields. This method situates the research participants and the researcher in a partnership in which everyone contributes through dialogue to the learning process. / Education, Faculty of / Language and Literacy Education (LLED), Department of / Graduate

El pensamiento visual favorece los procesos de enseñanza-aprendizaje en distintos campos del conocimiento. Sin embargo, no se conocen herramientas validadas que certifiquen la calidad del pensamiento visual. El objetivo de esta investigación es elaborar y validar un Manual de Evaluación de Pensamiento Visual que mida la calidad de las representaciones visuales a partir de seis criterios: Proximidad, Similitud, Continuidad, Jerarquía, Relación y Simplicidad. Para esto, se evaluó la validez de contenido mediante la V de Aiken (0.84) y la confiabilidad con la prueba de dos mitades que arrojó un valor favorable de 0.872. La normalidad se determinó bajo el criterio Shapiro-Wilk (n<30) obteniendo valores de significancia aceptables. Para contrastar el objetivo general y los específicos, se aplicó la prueba T de Student y rangos de Wilcoxon, obteniendo resultados favorables que sugieren que el manual propuesto puede avaluar pensamiento visual. / Visual Thinking promotes learning processes in different knowledge fields. However, there is no information available about any tools that evaluate the quality of visual thinking. The aim of this research is to elaborate and validate a Manual of Assessment of Visual Thinking, which evaluates the quality of the visual representations considering six criteria: proximity, similarity, continuity, hierarchy, relation and simplicity. For this, content validity was evaluated using Aiken's V (0.84) and the reliability with the split-half method (0.872). The normality was determined under the Shapiro-Wilk criterion (n<30) obtaining acceptable values. To contrast the general and specific objectives, T student test and ranges of Wilcoxon were applied, obtaining favourable results that suggest that the proposed Manual can assess Visual Thinking. / Tesis

Virtual environments are visually dominant systems. It seems that individuals" visual perception abilities would have an effect on their performance in a virtual environment. One such visual perception ability that seems a logical fit for study in virtual environments is that of disembedding ability. Disembedding ability is one part of a greater psychological construct known as field dependence. This research investigates how the learner characteristic of field dependence affects learning outcomes in virtual environments In order to examine the effect of virtual environments on recall among learners of differing levels of field dependence, the following specific questions and hypotheses were formed: 1) Does the use of virtual environments affect participants" performance in a task of recall? 2) Do participants of different levels of field dependence perform differently on a task of recall when presented with virtual environments versus static images? 3) Do field-dependent participants score higher on a test of recall when presented with a virtual environment? An experimental design using a sample of Virginia Tech students was employed in this study. The analysis consisted of a 2 X 2 factorial design with main effects for two levels of field dependence (field dependent and field independent), two levels of image representation (virtual environment versus static images), and interaction effects between the two factors. The factorial analysis showed no significant difference in recall test scores for the two treatments. Likewise, there was no significant difference in test scores for field dependent participants who received the virtual-environment treatment versus the static-image treatment. However, a significant interaction existed between field dependence and treatment type, favoring the field-independent participants who received the virtual-environment treatment. It can be concluded from this study that virtual environments have no effect on the recall ability of field-dependent learners. Further research might focus on other individual differences, such as spatial ability, that may have an effect on field-dependent learners" strategies for working in a virtual environment. / Ph. D.

The issue of the relative importance of early vs. delayed experience to behavioral development has proven to be a difficult one to address empirically. I focused on this issue by manipulating the timing of the onset of visual experience of avian embryos and hatchlings. Normally reared bobwhite quail chicks are known to require only maternal auditory cues to direct their social preferences in the first days following hatching. However, by 3 days following hatching quail chicks require both auditory and visual cues to direct their social preferences. In contrast, birds which have received unusually early visual experience as embryos require both auditory and visual cues on the day following hatching, indicating an accelerated pattern of the emergence of this type of early intersensory functioning. Hatchlings reared under conditions of delayed visual experience (deprivation) continue to rely on maternal auditory cues alone up to 4 days following hatching, and do not demonstrate a preference for combined audio-visual cues, indicating a decelerated pattern of the emergence of this type of early intersensory functioning. Here I report that quail chicks that received both early visual experience as embryos and delayed visual experience as hatchlings exhibit a pattern of intersensory functioning similar to that seen in normally reared chicks. That is, they do not require combined auditory and visual cues to direct their social preferences until 3 days following hatching. These results indicate that, at least under the present experimental conditions, the influence of early and delayed visual experience on the development of intersensory functioning is essentially equivalent. These findings are discussed in terms of the role of timing of sensory experience in early perceptual organization. / Master of Science

Thesis (M.Tech. - Graphic Design, Dept. of Visual Arts and Design, Faculty of Human Sciences) -- Vaal University of Technology / An exploratory study was undertaken at three campuses of the Vaal University of Technology in response to weak examination results in one of the subjects of the graphic design curriculum. The aim of the study was to investigate visual learning strategies as used in conjunction with co-operative learning approaches in a higher education setting and to asses the appropriateness of these learning approaches in the discipline of graphic design at first-year level. The research questions that guided the study focused on how first-year graphic design learners experience (a) visual learning strategies, (b) a cooperative learning environment, as well as (c) the combination of these. The literature review component of the study covered (1) the fundamentals of visual learning, including the concepts of visual literacy, visual semiotics and visual culture; (2) graphic design education, especially in a South African context; and (3) principles of co~operative learning, including Avenant's requirements for successful group work. In the field work component of the study, multiple-choice questionnaires, open-ended questionnaires and focus group interviews were used as the main data collection methods. The results of the study did not indicate that first-year learners enrolled in the discipline of graphic design are likely to benefit from a combination of visual learning and co-operative learning strategies. Therefore, the implementation of a combination of the above-mentioned teaching strategies is not recommended in this setting.

abstract: Body size plays a pervasive role in determining physiological and behavioral performance across animals. It is generally thought that smaller animals are limited in performance measures compared to larger animals; yet, the vast majority of animals on earth are small and evolutionary trends like miniaturization occur in every animal clade. Therefore, there must be some evolutionary advantages to being small and/or compensatory mechanisms that allow small animals to compete with larger species. In this dissertation I specifically explore the scaling of flight performance (flight metabolic rate, wing beat frequency, load-carrying capacity) and learning behaviors (visual differentiation visual Y-maze learning) across stingless bee species that vary by three orders of magnitude in body size. I also test whether eye morphology and calculated visual acuity match visual differentiation and learning abilities using honeybees and stingless bees. In order to determine what morphological and physiological factors contribute to scaling of these performance parameters I measure the scaling of head, thorax, and abdomen mass, wing size, brain size, and eye size. I find that small stingless bee species are not limited in visual learning compared to larger species, and even have some energetic advantages in flight. These insights are essential to understanding how small size evolved repeatedly in all animal clades and why it persists. Finally, I test flight performance across stingless bee species while varying temperature in accordance with thermal changes that are predicted with climate change. I find that thermal performance curves varied greatly among species, that smaller species conform closely to air temperature, and that larger bees may be better equipped to cope with rising temperatures due to more frequent exposure to high temperatures. This information may help us predict whether small or large species might fare better in future thermal climate conditions, and which body-size related traits might be expected to evolve. / Dissertation/Thesis / Doctoral Dissertation Biology 2018

The overarching goal of this dissertation was to evaluate the contextual components of instructional strategies for the acquisition of complex programming concepts. A meta-knowledge processing model is proposed, on the basis of the research findings, thereby facilitating the selection of media treatment for electronic courseware. When implemented, this model extends the work of Smith (1998), as a front-end methodology, for his glass-box interpreter called Bradman, for teaching novice programmers. Technology now provides the means to produce individualized instructional packages with relative ease. Multimedia and Web courseware development accentuate a highly graphical (or visual) approach to instructional formats. Typically, little consideration is given to the effectiveness of screen-based visual stimuli, and curiously, students are expected to be visually literate, despite the complexity of human-computer interaction. Visual literacy is much harder for some people to acquire than for others! (see Chapter Four: Conditions-of-the-Learner) An innovative research programme was devised to investigate the interactive effect of instructional strategies, enhanced with text-plus-textual metaphors or text-plus-graphical metaphors, and cognitive style, on the acquisition of a special category of abstract (process) programming concept. This type of concept was chosen to focus on the role of analogic knowledge involved in computer programming. The results are discussed within the context of the internal/external exchange process, drawing on Ritchey's (1980) concepts of within-item and between-item encoding elaborations. The methodology developed for the doctoral project integrates earlier research knowledge in a novel, interdisciplinary, conceptual framework, including: from instructional science in the USA, for the concept learning models; British cognitive psychology and human memory research, for defining the cognitive style construct; and Australian educational research, to provide the measurement tools for instructional outcomes. The experimental design consisted of a screening test to determine cognitive style, a pretest to determine prior domain knowledge in abstract programming knowledge elements, the instruction period, and a post-test to measure improved performance. This research design provides a three-level discovery process to articulate: 1) the fusion of strategic knowledge required by the novice learner for dealing with contexts within instructional strategies 2) acquisition of knowledge using measurable instructional outcome and learner characteristics 3) knowledge of the innate environmental factors which influence the instructional outcomes This research has successfully identified the interactive effect of instructional strategy, within an individual's cognitive style construct, in their acquisition of complex programming concepts. However, the significance of the three-level discovery process lies in the scope of the methodology to inform the design of a meta-knowledge processing model for instructional science. Firstly, the British cognitive style testing procedure, is a low cost, user friendly, computer application that effectively measures an individual's position on the two cognitive style continua (Riding & Cheema,1991). Secondly, the QUEST Interactive Test Analysis System (Izard,1995), allows for a probabilistic determination of an individual's knowledge level, relative to other participants, and relative to test-item difficulties. Test-items can be related to skill levels, and consequently, can be used by instructional scientists to measure knowledge acquisition. Finally, an Effect Size Analysis (Cohen,1977) allows for a direct comparison between treatment groups, giving a statistical measurement of how large an effect the independent variables have on the dependent outcomes. Combined with QUEST's hierarchical positioning of participants, this tool can assist in identifying preferred learning conditions for the evaluation of treatment groups. By combining these three assessment analysis tools into instructional research, a computerized learning shell, customised for individuals' cognitive constructs can be created (McKay & Garner,1999). While this approach has widespread application, individual researchers/trainers would nonetheless, need to validate with an extensive pilot study programme (McKay,1999a; McKay,1999b), the interactive effects within their specific learning domain. Furthermore, the instructional material does not need to be limited to a textual/graphical comparison, but could be applied to any two or more instructional treatments of any kind. For instance: a structured versus exploratory strategy. The possibilities and combinations are believed to be endless, provided the focus is maintained on linking of the front-end identification of cognitive style with an improved performance outcome. My in-depth analysis provides a better understanding of the interactive effects of the cognitive style construct and instructional format on the acquisition of abstract concepts, involving spatial relations and logical reasoning. In providing the basis for a meta-knowledge processing model, this research is expected to be of interest to educators, cognitive psychologists, communications engineers and computer scientists specialising in computer-human interactions.
