Examining the Creative Arts Doctorate in Australia: Implications for supervisors

Abstract

One of the significant roles performed by the higher degree research (HDR) supervisor is to assist students to prepare their dissertations for examination. At a time when there is increasing interest in how the academy manages the transition of creative arts HDR candidates from apprentice to peer, there is also concern about the processes, practices, and policies associated with this largely under-researched area of research training. In a recent national Office of Learning and Teaching funded project, we investigated the policy expectations, expert and peer beliefs and expectations, and examiners’ practice around HDR examination, and canvassed the creative arts academic community for their recommendations on best practice in the examination of creative arts doctorates. An unexpected finding was the role of the HDR supervisor in relation to these key areas, and the impact of supervisors upon the examination of students’ theses. This article presents our findings with special reference to the role, understandings, and aspirations of HDR supervisors in the context, and process, of preparing their students for creative arts HDR examination.     

A handheld preconcentrator for the rapid collection of cancerous cells using dielectrophoresis generated by circular microelectrodes in stepping electric fields

The ability to concentrate biological cells, such as circulating tumor cells, circulating fetal cells, and stem cells, is an important issue in medical diagnostics and characterization. The present study develops a handheld device capable of effectively preconcentrating cancerous cells. Circular microelectrodes were designed to generate a stepping electric field by switching the electric field to an adjacent electrode pair by relays. Cancerous cells with a positive dielectrophoretic response are guided toward the center of the circular microelectrodes due to the region of high electric field between the adjacent electrodes being gradually decreased in the direction of the stepping electric field. Numerical simulations of the electric fields were performed to demonstrate the concept of the proposed design. The preconcentration of HeLa cells, which are a human cervical carcinoma cell line, was achieved in 160 s with an efficiency of around 76%, with an applied peak-to-peak voltage of 16 V at a frequency of 1 MHz.     

The use of specially designed tasks to enhance student interest in the cadaver dissection laboratory

Cadaver dissection is a key component of anatomy education. Unfortunately, students sometimes regard the process of dissection as uninteresting or stressful. To make laboratory time more interesting and to encourage discussion and collaborative learning among medical students, specially designed tasks were assigned to students throughout dissection. Student response and the effects of the tasks on examination scores were analyzed. The subjects of this study were 154 medical students who attended the dissection laboratory in 2009. Four tasks were given to teams of seven to eight students over the course of 2 weeks of lower limb dissection. The tasks were designed such that the answers could not be obtained by referencing books or searching the Internet, but rather through careful observation of the cadavers and discussion among team members. Questionnaires were administered. The majority of students agreed that the tasks were interesting (68.0%), encouraged team discussion (76.8%), and facilitated their understanding of anatomy (72.8%). However, they did not prefer that additional tasks be assigned during the other laboratory sessions. When examination scores of those who responded positively were compared with those who responded neutrally or negatively, no statistically significant differences could be found. In conclusion, the specially designed tasks assigned to students in the cadaver dissection laboratory encouraged team discussion and collaborative learning, and thereby generated interest in laboratory work. However, knowledge acquisition was not improved.     

A Novice-Expert Study of Modeling Skills and Knowledge Structures about Air Quality

This study compared modeling skills and knowledge structures of four groups as seen in their understanding of air quality. The four groups were: experts (atmospheric scientists), intermediates (upper-level graduate students in a different field), advanced novices (talented 11th and 12th graders), and novices (10th graders). It was found that when the levels of modeling skills were measured, for most skills there was a gradual increase across the spectrum from the novices to the advanced novices to the intermediates to the experts. The study found the experts used model-based reasoning, the intermediates and advanced novices used relation-based reasoning, and the novices used phenomena-based reasoning to anticipate conclusions. The experts and intermediates used more bi-variable relationships in experimental design and anticipated conclusions, but used more multiple-variable relationships in identifying relationships. By contrast, the advanced novices and novices mostly used bi-variable relationships in all modeling skills. Based on these findings, we suggest design principles for model-based teaching and learning such as designing learning activities to encourage model-based reasoning, scaffolding one??s modeling with multiple representations, testing models in authentic situations, and nurturing domain-specific knowledge during modeling.     

Applying tangible story avatars to enhance children's collaborative storytelling

Software avatars are increasingly applied to support children's collaborative storytelling because avatars may serve as a transparent shield or as embodied agents to facilitate creativity in children. However, when using avatars, it is not easy for children to practise and refine their speaking skills by narrating their stories to an audience. The programming difficulties involved in that process tend to distract attention away from the collaborative storytelling activity itself. This study therefore proposes an interaction model featuring tangible story avatars (TSAs) that can serve as a platform to scaffold collaborative story creation, revision and narrative. A 9‐week study with 16 children aged 8 years was conducted to evaluate the interaction model with the TSAs. The results suggest that the TSAs may play three primary roles in facilitating collaborative storytelling: as a tool for developing confidence, as a tool for reflective story development and as a group artefact. Researchers and educators may find it valuable to consider these three roles in designing the TSAs in support of collaborative storytelling in similar contexts.     

Free to Learn: Helping Ex-Offenders with Reentry

Denver Public Library has taken an active role in providing services for people who have served time in prison or jail. The program Free to Learn focuses on providing resources and training to help ex-offenders with entering or reentering the workforce. Educating library staff on how to help felons also plays a critical role in the success of the program. This article provides information on how Denver Public Library helps ex-offenders apply for a job and respond to “the felony question.”
