Meaningful interaction: toward a new theoretical approach to online instruction

ABSTRACT

Taking full advantage of the educative benefits of interaction in digital learning environments will require the development of new theoretical frameworks that can contribute to a richer understanding of interaction. Literary theory provides an excellent place to develop such a framework and advanced understanding. Literary theory enables us to reconceptualise online courses as ‘texts’, thereby equipping us with more sophisticated modes of analysis for the teaching and learning process. By rethinking online courses as texts, and better yet as what Roland Barthes has described as ‘writerly’ texts, we can improve interaction in the online classroom. More importantly, we can move toward a more meaningful form of interaction, where learners interact with course content at the level of meaning and meaning making, where interaction becomes a full participation in the production of a lesson’s meaning. Indeed, this aim of co-producing meaning should be the primary objective of all learning.     

Development of auditory event-related potentials in young children and relations to word-level reading abilities at age 8 years

A relationship between brain responses at birth and later emerging language and reading skills have been shown, but questions remain whether changes in brain responses after birth continue to predict the mastery of language-related skills such as reading development. To determine whether developmental changes in the brain-based perceptual skills are systematically related to differences in word-level reading proficiency at age 8 years, brain event-related potentials (ERPs) to speech and nonspeech stimuli were recorded annually at the ages of 1 through 8 years in a sample of 109 typically developing children. Two measures of word-level reading (one that requires decoding of real words and one of pseudowords) were administered at age 8 years. Growth curve analysis, using the hierarchical linear models, related reading performance (average versus low) to the longitudinal maturation in the ERP waveform peak and latencies. Maturational changes (e.g., slope, acceleration, and cubic growth) in N1 amplitude from ages 1 to 4 were related to proficiency in decoding pseudoword stimuli only, with children who were less proficient in decoding pseudowords evidencing more steeply negative declines in amplitude with age, particularly at the frontal and parietal recording sites in response to both speech and nonspeech stimuli. In contrast, proficiency in decoding real words was related to developmental changes in N2 amplitudes from ages 4 to 8 only at the parietal recording site, and only in response to nonspeech stimuli. The early development of biologically based differences in the perception and processing of auditory information contributes to later group differences in reading proficiencies at school age.     

Prediction and prevention of child abuse and neglect

Utilizing an interview, a questionnaire, and observations during labor, delivery, and the postpartum period, a sample of one hundred mothers was identified as at high risk for abnormal parenting practices. These mothers were randomly divided into a “High-Risk Intervene” group (N=50) and a “High-Risk Nonintervene” group (N=50). The “Intervene” group received comprehensive pediatric follow-up by a single physician, a lay health visitor, and/or a public health nurse in the home. The “Non-intervene” group received routine care, although the results of these screening procedures were shared with the physicians and nurses responsible for their ongoing care. Another group of 50 mothers, who delivered during the same time period and who were assessed as low risk in terms of abnormal parenting practices, served as controls. When the children were approximately two years old (mean age 26.8 months), 25 families in each of the three groups were chosen at random for detailed evaluation.     

The Web and information literacy: scaffolding the use of web sources in a project-based curriculum

In this article we describe and discuss a three‐year case study of a course in web literacy, part of the academic literacy curriculum for first‐year engineering students at the University of Cape Town (UCT). Because they are seen as ‘practical’ knowledge, not theoretical, information skills tend to be devalued at university and rendered invisible to the students. In particular, web‐searching skills are problematic, given the challenges that the Web poses to academic values and traditional research practices. Consequently, the technical skills of web searching are often taught separately from academic curricula or left entirely unaddressed. We illustrate an alternative, integrated approach to the development of this aspect of information literacy. We apply a critical action research methodology to document, evaluate and reflect on students’ use of evaluative frameworks. Focusing on the facilitation of critical and evaluative use of the Web for exploratory learning, we interrogate the role of ‘cultural capital’ and evaluate the effectiveness of the scaffolding provided by the course design. We find important connections between developing knowledge of academic discourse and successful academic use of the Web, and note that, for students to transfer their skills to a range of contexts, these skills will require sustained attention throughout the undergraduate curriculum. We present evidence that the most effective strategies integrate everyday practical knowledge of research techniques with teaching about academic discourse and building students’ knowledge in a specific domain.     

Dance in computer technology: A survey of applications and capabilities

Conclusion Dance has made major incursions into the area of computer technology over the past 10 years. In this respect, it has more than rivalled the other arts and, in addition, has an even greater potential for reaching beyond current constraints and into the realm of vanishing horizons. Through computer and video technologies, dance has gained a potential and accelerated access to home audiences. Computer technology has also provided the art of dance with increased opportunities for creativity and experimentation, for literacy and for learning. In sum, and as a result, dance exemplifies the integration of artistic concerns and technological advances in today's world.     

A simple microscopy assay to teach the processes of phagocytosis and exocytosis

Phagocytosis and exocytosis are two cellular processes involving membrane dynamics. While it is easy to understand the purpose of these processes, it can be extremely difficult for students to comprehend the actual mechanisms. As membrane dynamics play a significant role in many cellular processes ranging from cell signaling to cell division to organelle renewal and maintenance, we felt that we needed to do a better job of teaching these types of processes. Thus, we developed a classroom-based protocol to simultaneously study phagocytosis and exocytosis in Tetrahymena pyriformis. In this paper, we present our results demonstrating that our undergraduate classroom experiment delivers results comparable with those acquired in a professional research laboratory. In addition, students performing the experiment do learn the mechanisms of phagocytosis and exocytosis. Finally, we demonstrate a mathematical exercise to help the students apply their data to the cell. Ultimately, this assay sets the stage for future inquiry-based experiments, in which the students develop their own experimental questions and delve deeper into the mechanisms of phagocytosis and exocytosis.     

The beliefs of teachers and daycare staff regarding children of divorce: A Q methodological study

This Q methodological study explores beliefs of daycare staff and teachers regarding young children’s reactions related to divorce. The Q factor analysis resulted in two viewpoints. Participants on the viewpoint “Child problems” believe that children show various emotional and behavioral problems related to divorce, while those on the “Structure is working” viewpoint believe structure in daycare centers and parental cooperation help children to overcome divorce-related difficulties. Selective perception based on subjective experiences may have influenced these views. Practical implications are discussed. Q methodology and cognitive interviewing techniques seem efficient in exploring daycare staff beliefs.
