Together, this dissertation describes the combined importance of visuality, pedagogy, and forces like power in deaf education. It documents a multimethod qualitative research design with case study and grounded theory methods to examine conflicting issues about "how" and "why" vision is used in deaf pedagogy. Initially,…

This study investigated the effects of multimedia and modality design principles using a learning intervention about Australia with a sample of college students and employing measures of learning outcomes, visual attention, satisfaction, and mental effort. Seventy-five college students were systematically assigned to one of four conditions: a)…

This study tested 3 instructor presence features in learning from video lectures: dynamic drawings, eye contact with the camera, and instructor visibility. In 2 experiments, college students watched a video lecture about the human kidney, which consisted of a series of drawings and a spoken explanation from the instructor, and then took a written…

This article reports the results of an ethnographic research about the multimodal science discourse in a sixth-grade sheltered classroom involving English Language Learners (ELLs) only. Drawing from the perspective of multimodality, this study examines how science learning is constructed in science lectures through multiple semiotic resources,…

The study examined whether the modality effect is caused by either high visuo-spatial load or a lack of temporal contiguity when processing written text and pictures. Students (N = 147) viewed pictures on the development of tornados, which were accompanied by either spoken or written explanations presented simultaneously with, before, or after the…

The focus and purpose of this paper is to present an e-learning teacher training course, including its aims and main results from teachers' interviews. The case study presented here examines the effectiveness of an in-service training seminar which was targeted toward teachers at multicultural schools. It concerns qualitative research that…

The purpose of the study reported on here was to explore ways in which the interactive whiteboard (IWB) can support students' understanding of texts. A Year 3 and a Year 4 primary school class in New South Wales, Australia, is the focus of the research. A qualitative case study was carried out using multimodal analysis focusing on the use of an…

"Present text accompanying pictures aurally to promote learning" is a well established principle of instructional design. But recently, it was shown that under certain conditions visual texts can be preferable. Instructional pacing seems to be one of these conditions that mediate effects. Especially, enabling learners to pace an…

Sensory overload and split attention result in reduced learning when instructors read slides with bullet points and complex graphs during a lecture. Conversely, slides containing relevant visual elements, when accompanied by instructor narration, use both the visual and verbal channels of a student's working memory, thus improving the chances of…

The present study examines how changes in the amount of on-screen text will influence student learning from a multimedia instructional unit on basic concepts of coordinate geometry. The relative effectiveness of two different versions (short-text and whole-text) of the instructional unit was examined for students who differed in terms of their…

The increasingly integrative use of images with language in many different types of texts in electronic and paper media has created an urgent need to go beyond logocentric accounts of literacy and literacy pedagogy. Correspondingly there is a need to augment the genre, grammar and discourse descriptions of verbal text as resources for literacy…
