Using constructed-response and multiple-choice questions in undergraduate examinations

This paper looks at the use of constructed-response and multiple-choice questions in first year management examinations involving 2364 students over a three semester period in 2008-9. It also compares student’s performance in research and analytical assignments with their results in Multiple-Choice tests. The results show that students who perform poorly in non-multiple-choice tests are slightly advantaged by multiple-choice tests. However, students who display high distinction scores in other pieces of assessment do not receive any advantage from multiple-choice testing. Interestingly, the research also highlighted that female students perform better in their articulation of management techniques overall, but do not gain the same comparative advantage from multiple choice testing. The analysis of the assessment methods was extremely useful in predicting the level of failures for the unit in the subsequent year. Finding the right balance of assessment tasks in first year university business courses is extremely difficult, using multiple-choice tests can be useful tool as part of the assessment mix in management units.

Assessment method difference : comparisons between international and domestic students within a first year undergraduate management course

This paper investigates the assessment methods and student results within a first year undergraduate management course offered within the business faculty of an Australian university. This course is compulsory for those studying for a commerce or management degree. The assessment results of full fee paying international students were compared with those of domestic students, during four teaching semesters in 2009 and 2010. Analysis compares 2,682 students’ numerical results for two constructed response assignments to their results for an examination comprising both multiple choice questions and constructed response questions. It also compares the results of international and domestic students across metropolitan, regional and rural campuses. However due to little comparison data for multiple campuses, findings are consolidated by domestic and international students, university-wide. International students were found to achieve lower results than domestic students for constructed response assessment tasks, but higher results than domestic students for multiple choice question assessments. These findings have implications for instructors eager to provide a level assessment playing field for both domestic and international students, enabling both groupings to take advantage of existing strengths but also to improve their weaknesses. This research led to a restructuring and rescheduling of assessment tasks for the 2012 academic year.

Modeling response rates in surveys of female sexual difficulty and dysfunction

INTRODUCTION: Studies that address sensitive topics, such as female sexual difficulty and dysfunction, often achieve poor response rates that can bias  results. Factors that affect response rates to studies in this area are not well characterized.
AIM: To model the response rate in studies investigating the prevalence of female sexual difficulty and dysfunction.
METHODS: Databases were searched for English-language, prevalence studies using the search terms: sexual difficulties/dysfunction, woman/women/female, prevalence, and cross-sectional. Studies that did not report response rates or were clinic-based were excluded. A multiple linear regression model was constructed.
MAIN OUTCOME MEASURES: Published response rates.
RESULTS: A total of 1,380 publications were identified, and 54 of these met our inclusion criteria. Our model explained 58% of the variance in response rates of studies investigating the prevalence of difficulty with desire, arousal, orgasm, or sexual pain (R(2) = 0.581, P = 0.027). This model was based on study design variables, study year, location, and the reported prevalence of each type of sexual difficulty. More recent studies (beta = -1.05, P = 0.037) and studies that only included women over 50 years of age (beta = -31.11, P = 0.007) had lower response rates. The use of face-to-face interviews was associated with a higher response rate (beta = 20.51, P = 0.036). Studies that did not include questions regarding desire difficulties achieved higher response rates than those that did include questions on desire difficulty (beta = 23.70, P = 0.034).
CONCLUSION: Response rates in prevalence studies addressing female sexual difficulty and dysfunction are frequently low and have decreased by an average of just over 1% per anum since the late 60s. Participation may improve by conducting interviews in person. Studies that investigate a broad range of ages may be less representative of older women, due to a poorer response in older age groups. Lower response rates in studies that investigate desire difficulty suggest that sexual desire is a particularly sensitive topic.

Beyond mimesis : place, interpretation and response

My study examines the subjective nature of artistic interpretation through the notion of mimesis as process or transformation of material. Influential factors that mediate in the artistic process, such as memory, reflection and an awareness of cultural analogy and metaphor, are examined and related to a specific project in the studio, where the mediation process is further influenced by the materials used to produce the images. My studies of the concept of mimesis have revealed an intermediary realm that exists in the space between empirical reality and its interpretation. Throughout history the process of mimesis has been integral to all forms of the arts. In Plato's time the production of an image that simulated things as they appeared to the eye was considered a desired ideal. Aristotle later introduced developments which extended this concept to include a refiguring or reforming of material derived from the original source, making new connections between existing factors and in this transformation bringing new meanings to a symbolically constituted world. This discussion of the representation of reality, the influence of a dialogue between notions of imitation and the recreation of material continues throughout the exegesis. My study emphasises the interpretive stage of the mimetic process where a consideration of these themes is most relevant and some of the factors that can influence its outcome. It is my opinion that the production of images in response to the particularities of place can be defined in three stages. Firstly, the experience of the place; secondly, the beginning and maturation of the idea or concept; where mimesis takes place, and thirdly, the production of the art work in response. This process is illustrated in Part 2 of the exegesis, where the development of the studio work is documented and linked with the themes discussed in Part 1. The geographic site or place I selected to study is adjacent to Mt. Noorat, a volcanic site in the Western district of Victoria; the surrounding plains are littered with scoria that has been thrown out of the volcano thousands of years ago. Early British, Scottish and Irish settlers to this region used the stone to construct fences reminiscent of their homeland, through this activity they cleared the land and confined and protected their stock. My interests are in factors that include - the material of the stone, notions of enclosure and safety, of boundaries and circumscribed space, and of the cultural reflection that has taken place in this reconstruction of Eurocentric vision. These walls also represent the means by which land was enclosed and property defined, moving from a situation of public access to notions of ownership and the annexation of land for individual gain. Around each point of eruption, the craggy volcanic scoria has been used to create a constructed landscape which both symbolises and mirrors the Anglo - Celtic origins of the people. I have used the legend of Narcissus to illustrate the self-reflective and introspective processes that the settlers invoked in their attempts to come to terms with a strange land. I consider that the story of Narcissus, who fell in love with his own reflection, finds a parellel in the creation of the walls. The re-creation of artifacts from their own cultural environment provided the settlers with a familiar 'face' in an alien world; a reassurance of the familiar in an unfamiliar terrain. Part of this study is an investigation of this notion of landscape as cultural reflection. Geographers have long known that landscape is a cultural construct, an historically evolving ideal manifested in painting, prints and drawings as well as poetry, gardens and parks. One can view these constructions as illustrations or images of meaning which constitute representations of cultural ideals. The neo-classical influence reflected in the paintings of artists who accompanied the early expeditions to Australia demonstrates these themes. The medium of the mirror provides the opportunity to suggest aspects of a cultural reflection and an awareness of identity that has relevance to contemporary Australian culture, therefore, I have allowed it to play a major role throughout this study. Its role in mimesis, firstly, as a reflection in an imitative sense is established, then in its refigurative role, in which the similarities between the original and the reformed rely more on correlative factors than representation. I have used examples from the history of art to illustrate this potential. The formation and development of a narrative involving reflection threads throughout the thesis, both in the visual presentation and in the exegesis. The production of a body of paintings, drawings and sculpture reflect my interpretation and response to the particular site. The correspondences between these works and my theoretical concerns is articulated in the exegesis. The metaphor implied by the use of the walls as agents of enclosure also refers to the capacity of the individual to be confined by notional boundaries and restrictive practices where totalising systems of thought dominate theoretical debate and restrict its freedom. I have used images where gaps in the walls represent the potential implicit to the concept of liminal space, where the spectator moves from one physical space to another and from one stage of development to another. The threshold of this opening in the walls becomes the site where transformation can take place, a metaphor for the mimetic process where the initial experience is translated and transformed into the final product. The paintings, drawings and other works in this series fulfil the role of marks on the surface of the mirror, separating the initial experience from the processes of memory, reflection and speculation. The works draw attention to the materiality that they represent and yet provide the opportunity for new insights and experiences, allowing the subjective nature of artistic activity to combine symbolic elements relating to the site, resulting in the production of meaning.

Relationship between wearer prickle response with fibre and garment properties and Wool ComfortMeter assessment

The prickle evoked by 48 knitted fabrics was assessed by wearers under a defined evaluation protocol. The relationship between the average wearer prickle score and known properties of constituent fibre, yarns and fabrics and fabric evaluation using the Wool ComfortMeter (WCM) was determined using linear modelling. After log transformation, the best model accounted for 87.7% of the variance. The major share of variation could be attributed to differences between mean fibre diameter (MFD) and WCM values. Low prickle scores were linearly associated with lower MFD, lower WCM and lower yarn linear density. There was an indication that yarn twist affected prickle scores and that fabrics composed of cotton evoked less prickle. Measures of fibre diameter distribution or coarse fibre incidence and other fabric properties were not significant. The analysis indicates that wool garments can be constructed to keep wearer assessed prickle to barely detectable levels and textile designers can manipulate a range of parameters to achieve similar wearer comfort responses.
