There has been a threefold increase in the employment of casual academics in Australian universities within the last 20 years, to the extent that most teaching and marking is now undertaken by casual academics, also known as sessional staff. Yet, casualised teaching and assessment has been considered a risk to student engagement and success, and casual academics report a lack of professional development and increased feelings of marginalisation within the academy. Concurrently, the quality assurance of teaching and assessment in higher education has become a central focus of the government-funded regulatory organisation, the Tertiary Education Quality and Standards Agency (TEQSA). Situated within this context, we report on an assessment moderation process that could support casual academics’ contextualised professional development, generate a sense of connectedness and collegiality and fulfil the requirements of TEQSA. Such processes may ensure that workforce growth in the higher education system supports a robust quality assurance and regulatory framework. 相似文献

The design and fabrication of a membrane-integrated microfluidic cell culture device (five layers,≤500 μm total thickness) developed for high resolution microscopy is reported here. The multi-layer device was constructed to enable membrane separated cell culture for tissue mimetic in vitro model applications and pharmacodynamic evaluation studies. The microdevice was developed via a unique combination of low profile fluidic interconnect design, substrate transfer methodology, and wet silane bonding. To demonstrate the unique high resolution imaging capability of this device, we used oil immersion microscopy to image stained nuclei and mitochondria in primary hepatocytes adhered to the incorporated membrane 相似文献

Early adolescents may lack the cognitive and metacognitive skills necessary for effective inquiry learning. In particular, they are likely to have a nonnormative mental model of multivariable causality in which effects of individual variables are neither additive nor consistent. Described here is a software‐based intervention designed to facilitate students' metalevel and performance‐level inquiry skills by enhancing their understanding of multivariable causality. Relative to an exploration‐only group, sixth graders who practiced predicting an outcome (earthquake risk) based on multiple factors demonstrated increased attention to evidence, improved metalevel appreciation of effective strategies, and a trend toward consistent use of a controlled comparison strategy. Sixth graders who also received explicit instruction in making predictions based on multiple factors showed additional improvement in their ability to compare multiple instances as a basis for inferences and constructed the most accurate knowledge of the system. Gains were maintained in transfer tasks. The cognitive skills and metalevel understanding examined here are essential to inquiry learning. © 2003 Wiley Periodicals, Inc.

Public libraries that practice effective dialogic communication are more likely to build trust with their communities. Applying principles of dialogic communication as a theoretical framework, this study examines how public libraries in Canada and the USA use Twitter to build long-term positive relationships with their publics. Content analysis of 28,788 Twitter messages sent to and from thirteen library @names revealed that libraries tend to employ the ‘dialogic cluster’ principles more often than the ‘technical and design cluster’ ones. However, ‘technical and design cluster’ messages were more likely to be retweeted. The number of followers was found to be positively related to the frequency of trust messages that the Twitter users send to a library @name. The authors discuss communication practices to actively engage publics in dialogic communication on Twitter. 相似文献

The value and importance of lectures in higher education is part of a modern education discourse worldwide. This study aims to estimate the importance of lectures for prospective teachers of kindergarten, preschool and early primary school. We analysed academic achievements of prospective teachers who had either mandatorily or voluntarily attended lectures in the subject of teaching and learning mathematics. Students’ examination grades in a maths course with mandatory or voluntary lecture attendance were analysed with a logistic model testing the association between lecture attendance requirement and grades. We show that mandatory lecture attendance (1) more than double the odds of students receiving a pass grade when their situated and tacit knowledge was examined and (2) quadrupled the odds of students achieving the highest grade (pass with distinction) when both their understanding of elementary mathematics and their situated and tacit knowledge of teaching and learning mathematics were examined. Our study provides evidence for a significant positive role of lecture attendance for students acquiring skills in Teaching and Learning Mathematics. While attending lectures students receive situated tacit knowledge of the subject which is otherwise difficult, if not impossible, for them to obtain in a different way. The observed improvement may have an additional positive effect in being a step towards overcoming a maths anxiety, which is otherwise relatively common among prospective teachers. 相似文献

This is a report on the impact of library workers'' personal beliefs on provision of vaccination information. Nine public librarians were interviewed about a hypothetical scenario involving a patron who is concerned about possible vaccination-autism connections. The analysis employed thematic coding. Results suggested that while most participants supported childhood vaccination, tension between their personal views and neutrality impacted their ability to conduct the interaction. The neutrality stance, though consonant with professional guidelines, curtails librarians'' ability to provide accurate health information. Outreach and communication between public and health sciences libraries can help librarians provide resources to address health controversies. 相似文献

Community college remedial reading studentscomposed an informational report from sources,a task commonly assigned in higher educationthat integrally combines reading and writingprocesses. Productivity, use of source text,reproductions, accuracy, and inclusion of keyideas were analyzed as a function of twoexogenous variables, text density (high, low)and domain (health, business), and twoendogenous variables, prior knowledge andgeneral literacy skill. Text densityinteracted with literacy skill forproductivity, and with prior knowledge foraccuracy. Individuals with lower literacy orprior knowledge scores were at a disadvantagewith high but not low density source text. Domain affected productivity, use of source,and inclusion of key ideas: health text wasassociated with superior performance. Domaineffects may be explained by metacognitive ormotivational variables, or differences in thereadability of the source texts. The resultshave implications for instruction aimed atimproving community college students'preparedness for the academic demands of highereducation. 相似文献
