Abstract: The transition from high school to tertiary education can be a daunting prospect for students. The prospect of laboratories, an unfamiliar environment, for students, can increase levels of anxiety. Moreover, there is a growing body of evidence that suggests that students’ self-efficacy is inversely correlated with students’ anxiety. We surveyed students at the start and end of a semester to evaluate levels of anxiety and self-efficacy in relation to several aspects of the chemistry laboratory. Time management and answering assessed questions are the aspects that contribute to high levels of anxiety and low levels of self-efficacy at the start of semester. Students generally reported lower anxiety and higher self-efficacy at the end of the semester about every aspect probed. These results are of interest to any discipline that offers an unfamiliar learning environment for students as aspects such as time management and answering assessed questions are not discipline specific. We investigated the different aspects of anxiety and self-efficacy in relation to various demographic factors.

Abstract: Controlling the growth of the polymorphs of calcium carbonate is important in understanding the changing environmental conditions in the oceans. Aragonite is the main polymorph in the inner shells of marine organisms and can be readily converted to calcite, which is the most stable polymorph of calcium carbonate. Both of these polymorphs are significantly more stable than vaterite, which is the other naturally occurring polymorph of calcium carbonate and this is reflected in its limited distribution in nature. We have investigated the effect of high shear forces on the phase behaviour of calcium carbonate using a vortex fluidic device (VFD), with experimental parameters varied to explore calcium carbonate mineralisation. Variation of tilt angle, rotation speed and temperature allow for control over the size, shape and phase of the resulting calcium carbonate.

Abstract: We study plasmonic nanoantennas for molecular sensing in the mid-infrared made of heavily doped germanium, epitaxially grown with a bottom-up doping process and featuring free carrier density in excess of 1020 cm−3. The dielectric function of the 250 nm thick germanium film is determined, and bow-tie antennas are designed, fabricated, and embedded in a polymer. By using a near-field photoexpansion mapping technique at λ = 5.8 μm, we demonstrate the existence in the antenna gap of an electromagnetic energy density hotspot of diameter below 100 nm and confinement volume 105 times smaller than λ3.

Abstract: Student feelings towards the laboratory component of an introductory chemistry unit were evaluated in an action research study, over a three-year period at the University of Western Australia. In 2013 we found that the percentage of students with negative feelings towards the laboratory increased over the duration of a semester. In 2014 we developed and introduced the use of pre-laboratory online activities, which the students found to be helpful in preparing them for the laboratory. However, there was no change in trend of negative feelings towards laboratory classes from 2013 to 2014. In 2015 we introduced the Prepare, Do, Review model and found that there was a reduction in the percentage of students with negative feelings towards laboratory classes compared with previous years. The Prepare, Do, Review model allows students more time to process the information given in the laboratory. We believe that this model could apply to laboratory programs in any discipline.

Abstract: Most students acknowledge shared responsibility, with the university, for their employability development. Many academics use assessments as the main driver for motivating students to learn. At the intersection between employability, assessment and learning, the emergent research question is - what are the mechanisms by which course-based employability is fostered? Prior research reveals that although academics identified course-based assessment as the key employability mechanism, neither students nor employers registered this conceptualisation, and thus purpose of assessment. The aim of this research was to stimulate and communicate the direct connection between assessment and employability to students and interpret their response. Over 100 first-year students, across a metropolitan and regional Australian university, participated. Students were directed to use a simple reflective tool, dubbed iASK by the researchers, that probed employability elements of identity, Attributes, Skills, and Knowledge. The research revealed the resulting student view that regular course-based assessment can develop their employability skills in communication and independence, but not in critical thinking and global citizenship.

Abstract: Change in higher education creates many risks to the sustainability of teaching practices. In this paper, we review some perspectives and resources on change in higher education and examine strategies for educators to participate in sustainable change. Central to this is the role of local mission statements, formulated to consciously reflect common values and purpose within a team of colleagues, and used to guide decision making, particularly in times of change. This discussion considers changes in teaching practice, such as those required for active learning, informed by principles concerning general organisational change, and specific qualities of contemporary higher education in the sciences.

Abstract: This study investigated two student cohorts enrolled in an introductory tertiary chemistry unit designed for students with little or no previous education in chemistry. Emeritus Professor Graham Chandler was instrumental in the design and development of this unit almost 30 years ago. Therefore, this study has particular interest in this special issue of the Australian Journal of Chemistry, which celebrates Emeritus Professor Graham Chandler’s contribution to Australian chemistry. This paper is ided into two distinct parts that provide two unique perspectives of the unit. The first perspective, Part A, is a historical account of the origins of this unit and is based on an interview with E/Prof. Chandler and Dr Peter Simpson OAM. Both E/Prof. Chandler and Dr Simpson provide an excellent reflection on the need for an introductory chemistry unit in tertiary education, which was not as common then as it is in the present day. The second perspective, Part B, is a research study focussing on the perceptions of students taking this unit in 2013 and 2014. In this study, it was found that the number of students who perceived chemistry to be applicable to real world problems increased during the unit, as did the number of students who enjoyed the unit. However, many students, most of whom did not intend to study chemistry further, did not recognise the application of the content to their future careers. There are many similarities between the aims of E/Prof. Chandler and Dr Simpson for the unit and the perceptions of students taking this unit 30 years later, which is testament to Graham’s contribution to chemistry education at the University of Western Australia.

Abstract: Computational techniques are widely used to explore the structure and properties of nanomaterials. This review surveys the application of both quantum mechanical and force field based atomistic simulation methods to nanoparticles, with a particular focus on the methodologies available and the ways in which they can be utilised to study structure, phase stability and morphology. The main focus of this article is on partially ionic materials, from binary semiconductors through to mineral nanoparticles, with more detailed considered of three ex les, namely titania, zinc sulphide and calcium carbonate.

Abstract: The goals of this study are to use density functional theory to study the core structure energetics of the 30° and 90° partial dislocations in HgTe, CdTe, and Hg 0.7 Cd 0.3 Te as well as the density of states of these dislocations in CdTe and Hg 0.7 Cd 0.3 Te. For the 30° partial dislocations, two stable dislocation pairs were found. The pair with a double‐periodic α‐core (Te) dislocation and a single‐periodic β‐core (Hg/Cd) dislocation was found to be the most stable out of the two for the simulation sizes tested. For the 90° partial dislocations, two stable dislocation pairs were also found. The first has a single‐periodic β‐core dislocation and a single‐periodic α‐core dislocation, whereas the second has a double‐periodic β‐core dislocation and a single‐periodic α‐core dislocation. The most stable out of the two depends on the simulation size tested. For both of these partial dislocations in Hg 0.7 Cd 0.3 Te, it was found that it is energetically favourable for Hg atoms to segregate to the dislocation cores. Furthermore, in CdTe and Hg 0.7 Cd 0.3 Te, it was found that the 90° partial dislocations are likely to be more detrimental to the material optoelectronic properties since they introduce more mid‐gap states within the band gap in comparison to the 30° partial dislocations.
