Social networking and teaching : an Australian case study

In recent years, the Internet has impacted all aspects of modern society. We have now seen the phenomenon of social networking and the impact that this had upon all aspects of modern society including higher education. An issue is how can these social networking technologies relate to tertiary education and how can they be used in this educational context. This paper is based on two case studies which were conducted at an Australian University into the usage of two social networking systems in a teaching environment. The results of these case studies were assessed using a socio-technical framework.

Teaching the scientific method in the curriculum

 In chemistry education, students not only learn chemical knowledge and skills, but about the culture of chemistry – how scientists think about, and practise, chemistry. Students often learn that science is practised according to the “scientific method”, which is a model of scientific discovery, expounded by science historians and philosophers. The idealised “scientific method” has a number of steps: the collection of information about a phenomenon; the development of a hypothesis to explain those observations; an experiment to test a prediction that arises from the hypothesis, perhaps including more observations and collection of more information; improvement of the hypothesis; and so on.

The problem is that students (and even some science professionals) often do not understand the philosophy behind the scientific method and paradoxically, the scientific method does not seem to apply to most careers in science. The true nature of science is that concepts have been developed though variants of the “scientific method”, and that a process of testing the predictive value of these concepts has lead to advances in that conceptual knowledge. Hence the “scientific method” applies to the development of scientific ideas, not necessarily to the work of all scientists. It is not whether we personally use the scientific method in our day-today work, but how we use, apply, think about and communicate scientific knowledge and skills that makes us chemists.

Growth of pre-service teachers’ knowledge and teaching ideas about decimals and fractions : The case of Vivi

This paper discussed and analysed the growth of one pre-service teachers’ knowledge about decimals and fractions during a teaching experiment. Evidence of her progress is based on responses to written test and interview questions. This case shows with probing questions and appropriate teaching ideas, it is possible for a pre-service teacher with initially weak and fragmented knowledge about decimals and fractions to develop a meaningful knowledge about decimals and fractions. The stronger conceptual base provided by use of a concrete representation of decimals enabled Vivi to move away from reliance on memorised facts and rules and towards conceptually based explanations of ideas.

An inquiry into the effectiveness of student generated MCQs as a method of assessment to improve teaching and learning

 In anticipation of helping students mature from passive to more active learners while engaging with the issues and concepts surrounding computer security, a student generated Multiple Choice Question (MCQ) learning strategy was designed and deployed as a replacement for an assessment task that was previously based on students providing solutions to a series of short-answer questions. To determine whether there was any educational value in students generating their own MCQs students were required to design MCQs. Prior to undertaking this assessment activity each participant completed a pre-test which consisted of 45 MCQs based on the topics of the assessment. Following the assessment activity the participants completed a post-test which consisted of the same MCQs as the pre-test. The pre and post test results as well as the post test and assessment activity results were tested for statistical significance. The results indicated that having students generate their own MCQs as a method of assessment did not have a negative effect on the learning experience. By providing a framework to the students based on the literature to support their engagement with the learning material, we believe the creation of well-structured MCQs resulted in a more advanced understanding of the relationships between the concepts of the learning material as compared with plainly answering a series of short-answer questions from a textbook. Further study is required to determine to what degree this learning strategy encouraged a deeper approach to learning.

Optimizing safety, fidelity and usability of an Intelligent Clinical Support Tool (ICST) for acute hospital care: an Australian case study using a multi-method Delphi Process

This research focuses on a major health priority for Australia by addressing existing gaps in the implementation of nursing informatics solutions in healthcare. It serves to inform the successful deployment of IT solutions designed to support patient-centered, frontline acute healthcare delivery by multidisciplinary care teams. The outcomes can guide future evaluations of the contribution of IT solutions to the efficiency, safety and quality of care delivery in acute hospital settings.

Ultra-wideline 14N solid-state NMR as a method for differentiating polymorphs: glycine as a case study

Nitrogen-14 solid-state NMR (SSNMR) is utilized to differentiate three polymorphic forms and a hydrochloride (HCl) salt of the amino acid glycine. Frequency-swept Wideband, Uniform Rate, Smooth Truncated (WURST) pulses were used in conjunction with Carr-Purcell Meiboom-Gill refocusing, in the form of the WURST-CPMG pulse sequence, for all spectral acquisitions. The ¹⁴N quadrupolar interaction is shown to be very sensitive to variations in the local electric field gradients (EFGs) about the ¹⁴N nucleus; hence, differentiation of the samples is accomplished through determination of the quadrupolar parameters CQ and ηQ, which are obtained from analytical simulations of the ¹⁴N SSNMR powder patterns of stationary samples (i.e., static NMR spectra). Additionally, differentiation of the polymorphs is also possible via the measurement of ¹⁴N effective transverse relaxation time constants, T^eff2(¹⁴N). Plane-wave density functional theory (DFT) calculations, which exploit the periodicity of crystal lattices, are utilized to confirm the experimentally determined quadrupolar parameters as well as to determine the orientation of the ¹⁴N EFG tensors in the molecular frames. Several signal-enhancement techniques are also discussed to help improve the sensitivity of the ¹⁴N SSNMR acquisition method, including the use of selective deuteration, the application of the BRoadband Adiabatic INversion Cross-Polarization (BRAIN-CP) technique, and the use of variable-temperature (VT) experiments. Finally, we examine several cases where ¹⁴N VT experiments employing Carr-Purcell-Meiboom-Gill (CPMG) refocusing are used to approximate the rotational energy barriers for RNH3⁺ groups.

Uncertainty and reluctance in teaching taboo language: a case study of an experienced teacher of English as an additional language

Despite its ubiquitous employment by users of English to achieve authentic communicative goals, taboo language has received little attention in the education literature. Even less focus has been placed on such language in English language teaching - specifically, in teaching English as an Additional Language (EAL). Given the multiplicity of communicative struggles experienced by EAL learners surrounding the use of taboo language in authentic communication, meaningful consideration of this aspect can be seen as crucial in EAL instruction. Classroom learning could prepare learners for navigation and negotiation of taboo language use they will inevitably encounter in social interactions in target language communities of practice. However, EAL teachers' uncertainty or reluctance to introduce taboo language in classroom instruction is a key impediment in developing learners' sociocultural knowledge regarding such language use. We foreground one case of such uncertainty and reluctance surrounding the introduction of taboo language in EAL instruction derived as interview data from an experienced EAL teacher.

Fostering cultural diversity in Australia: a case study of teaching, learning and assessing African musical arts

Australia is forged by ongoing migration welcoming a range of cultures, languages and ethnicities thus celebrating a diverse range of musical arts. In this multicultural society, music and dance may serve as a positive medium to transmit and promote social cohesion. I argue that the inclusion of innovative and immersive practice of African music in particular where authentic teaching and learning is facilitated may help foster understandings of culture in educational settings and the wider society. As a migrant forming part of the African Diaspora in Melbourne, I am strongly connected to my ancestral homeland (South Africa) when teaching African music to Australian tertiary students. Having gained ethical clearance to undertake the two research projects at Deakin University in Melbourne (Attitudes and perceptions of Arts Education Students: preparing culturally responsive teachers and Pre-service teacher attitudes and understandings of Music Education), I discuss tertiary students experience in relation to the teaching and learning of African music within higher education courses. Drawing on interview, questionnaire, observation notes, anecdotal feedback and narrative reflection, I employ Interpretative Phenomenological Analysis to analyse and code the data into themes. By offering a discussion of assessment and evaluation, I explore and invite international dialogue in regards to how best we can prepare, assess and evaluate our students to improve the quality of musical arts education.

Articulations of teaching practice: a case study of teachers and "general capabilities"

The research reported on in this paper is a qualitative case study of secondary school teachers’ interpretations of how they work with a component of the Australian national curriculum, the seven “general capabilities.” The case study of four secondary school teachers utilized teacher interviews eliciting via descriptive analysis how teachers understand and work with the “general capabilities.” The Australian curriculum listing explicit “general capabilities” alongside endorsed disciplines and cross-curriculum priorities requires teachers and their associated classroom practice(s) bond to practical dexterities. Policy expectations are such that the knowledge, skills, behaviors and dispositions of the “general capabilities,” along with curriculum content and cross-curriculum priority areas will support students to successfully live and work in the twenty-first century. While policy expectations appear well defined, including expectations that teachers navigate and implement relevant curriculum in creative ways, the study underpinning this paper finds that teachers assert their professional and pedagogic authority over the curriculum by enacting and translating it for the benefit of their students.
