Mode 2 knowledge and institutional life: Taking Gibbons on a walk through a South African university

This paper examines the response of a blackuniversity in South Africa to the challengesposed by the mode 2 knowledge thesis of MichaelGibbon. The case material is based on theFaculty of Engineering at the University ofDurban Westville, which in the period 1999–2000grappled with the implications of Gibbonsthesis for knowledge, inquiry and professionalidentity in a proposed university-industrypartnership. The author argues that entrenchedinstitutional rules and behaviours threaten toundermine any attempt to rethink the researchand practice of engineering education even whensuch restructuring appears to work in the bestinterest of students.     

Feedback-seeking behavior in second language writing: motivational mechanisms

Focused on the effects of different type of feedback on learners’ written products, research on written corrective feedback (WCF) has cast second language writers as passive recipients rather than proactive agents in the feedback process. Revisiting the notion of WCF, this study introduces the notion of feedback-seeking behavior (Ashford & Cummings, 1983) to the field of second language writing and examines its motivational mechanisms using Dweck’s (1999) theory of mindsets and an overarching cost-value analysis framework (e.g., Ashford & Cummings, 1983; Anseel et al., 2015). Questionnaire data were collected from 128 foreign language writers from a major public university in the United States. Multiple regression and mediation analyses showed that a growth language mindset predicted the value of feedback, which, in turn, was a strong predictor of both feedback monitoring and feedback inquiry. A fixed language mindset, on the other hand, predicted the cost of feedback seeking, which, in turn, negatively predicted feedback monitoring. The findings offer new venues for second language writing research and pedagogy.

     

CAVEman: Standardized anatomical context for biomedical data mapping

The authors have created a software system called the CAVEman, for the visual integration and exploration of heterogeneous anatomical and biomedical data. The CAVEman can be applied for both education and research tasks. The main component of the system is a three‐dimensional digital atlas of the adult male human anatomy, structured according to the nomenclature of Terminologia Anatomica. The underlying data‐indexing mechanism uses standard ontologies to map a range of biomedical data types onto the atlas. The CAVEman system is now used to visualize genetic processes in the context of the human anatomy and to facilitate visual exploration of the data. Through the use of Java? software, the atlas‐based system is portable to virtually any computer environment, including personal computers and workstations. Existing Java tools for biomedical data analysis have been incorporated into the system. The affordability of virtual‐reality installations has increased dramatically over the last several years. This creates new opportunities for educational scenarios that model important processes in a patient's body, including gene expression patterns, metabolic activity, the effects of interventions such as drug treatments, and eventually surgical simulations.

Exploring students’ engineering designs through open-ended assignments

ABSTRACT

This paper aims at presenting the experience of the Power Conversion project in teaching students to design a proof-of-principle contactless energy transfer system for the charging of electrical vehicles. The Power Conversion is a second-year electrical engineering (EE) project in which students are to gather and apply EE knowledge to design and test a system. This system is to work with power level and operates independent from an electricity grid. The instructional method used in this project is design-based learning (DBL). As an educational approach, DBL is to support students to gather and apply knowledge in open-ended assignments. The set-up of the project has gone through different modifications and iterations in three consecutive years regarding the organisation and supervision of the students. We have analysed the students’ design products in the past three academic years in order to evaluate whether the project set-up and supervision have influenced students’ designs. Results indicate that the open-ended character of the project has a positive influence on the designs especially regarding the criteria on efficiency, Maximum Power Point Tracking algorithm and power tracking.     

Family risks and protective factors: Pathways to Early Head Start toddlers’ social-emotional functioning

Early Head Start children may be more likely to exhibit difficulties with social-emotional functioning due to the high-risk environments in which they live. However, positive parenting may serve as a protective factor against the influence of risk on children's outcomes. The current study examines the effects of contextual and proximal risks on children's social-emotional outcomes and whether these effects are mediated by maternal sensitivity. One-hundred and fourteen low-income, high-risk mother-toddler dyads participated in this longitudinal study designed to examine the relationships between family risk, mothers’ sensitivity, and children's social-emotional functioning in Early Head Start families. Researchers conducted two 2.5-h home visits, approximately six months apart, during which they assessed mothers’ levels of family risk, maternal sensitivity, and their children's social-emotional functioning. A theoretically derived structural equation model was tested to examine the direct paths from family risk variables to children's social-emotional functioning and the indirect paths by way of the mediator variable, maternal sensitivity. Support was found for a model that identified maternal sensitivity as a mediator of the relationship between parenting stress and children's social-emotional functioning. Results have implications for providing services through Early Head Start programs that are aimed at alleviating parenting stress and enhancing maternal sensitivity.     

Exploring a Science Teacher’s Uncertainty with Integrating Engineering Design: An Action Research Study

This study examines a fifth grade science teacher’s attempts at integrating engineering design using the construct of uncertainty. Collaborative action research served as a supportive mechanism to uncover and confront the teacher’s uncertainties. Data were gathered through semi-structured interviews, reflections, classroom observations, lesson plans, and student work. Data analysis entailed the use of grounded theory. Findings from this study revealed that teaching science through engineering design is both challenging and problematic. Underpinning the teacher’s pedagogical experiences was the constant force of uncertainty, in various forms, and how her sense of doubt was beneficial rather than problematic.     

The Effects of Videoconferencing,Class Size,and Learner Characteristics on Training Outcomes

ABSTRACT We examined direct and interaction effects of learners' characteristics (cognitive ability, prior knowledge, prior experience, and motivation to learn) and classroom characteristics (videoconferencing and class size) on learning from a 16-week course. A 2times2 quasi-experimental design varied the class size between large (∼60 students) and small (∼30 students) and between traditional classes with the instructor always present and classes taught using a videoconferencing system with the instructor present at each site every other week. Theory regarding instructor immediacy was used to predict that larger and videoconferenced classes would have negative effects on learner reactions and learning, but that highly motivated learners would overcome the negative effects on learning. Interactions between videoconferencing and motivation to learn, and class size and motivation to learn, were found in support of the theory. Research and practice implications are discussed.     

A Review of Engagement with Creativity and Creative Design Processes for Visual Communication Design (VCD) Learning in China

Understanding the enigma of how learners from the Peoples Republic of China enact and engage with creativity and creative design processes can be problematic for VCD educators. Central to the concerns are questions which relate to the relevance of Western creative and creative design process definitions, explanations and models. This review provides an overview and analysis of the literature in this area. Findings indicate challenges attributed to a dearth of empirical evidence from the Asian region. However, a number of studies were found, which enabled learner engagement with creative design process models. Such models may help illuminate complex pictures of learners’ interactions, artefacts, social, cultural and historic forces. The review highlights issues and common areas upon which to build and prompts theoretical and methodological approaches for future creative design process research.     

A Comparison of Item Sampling Plans in the Application of Multiple Matrix Sampling

This study used a Monte Carlo approach to investigate the effect of item sampling by item stratification on parameter estimation when applying multiple matrix sampling to achievement data. From the results of this study it was concluded that the item sampling method and sampling plan which is a practical compromise in terms of precision and sample size is one based on item stratification by item discrimination and a sampling plan with a moderate number of subtests. This sampling condition provides reasonable precision of the mean and variance estimates but requires only a moderately sized sample.
