Harnessing technology to improve formative assessment of student conceptions in STEM: forging a national network

Concept inventories, consisting of multiple-choice questions designed around common student misconceptions, are designed to reveal student thinking. However, students often have complex, heterogeneous ideas about scientific concepts. Constructed-response assessments, in which students must create their own answer, may better reveal students' thinking, but are time- and resource-intensive to evaluate. This report describes the initial meeting of a National Science Foundation-funded cross-institutional collaboration of interdisciplinary science, technology, engineering, and mathematics (STEM) education researchers interested in exploring the use of automated text analysis to evaluate constructed-response assessments. Participants at the meeting shared existing work on lexical analysis and concept inventories, participated in technology demonstrations and workshops, and discussed research goals. We are seeking interested collaborators to join our research community.     

Drivers of illicit drug use regulation in Australian sport

Most Australian sport stakeholders not only believe that government regulation is a good thing, but also assume that intervention in the drug-use problem will improve sport's social outcomes and operational integrity. In this paper we examine the regulation of illicit drug use in Australian sport through an interrogation of two cases: the Australian Football League and the National Rugby League. Using Pierre Bourdieu's conceptual frames of social field, capital, and habitus, we aim to secure a clearer understanding of the drivers of Australian sport's illicit drug regulations by (1) identifying those stakeholders who set the drug regulation agenda, (2) revealing the values and dispositions that underpin these regulations, and (3) explaining how dominant stakeholders go about sustaining their position and marginalising those stakeholders with opposing drug regulation claims. Our results show that Australian sport's drug-use regulations are driven by a set of values and dispositions that views sport as an instrument for shaping the character of its participants, and drugs as a threat to sport's moral fabric and good standing. The dominant stakeholders, comprising the Commonwealth Government, its sport agencies, and the major governing bodies for sport, imposed these values and dispositions on peripheral stakeholders by designing a drugs-in-sport social field that yielded capital and power to only those participants who endorsed these values and dispositions. Peripheral stakeholders – including players, their agents, and drug-treatment professionals – who mostly shared different values and dispositions, were sidelined, and denied the opportunity of adding to their already limited supplies of capital, power, and policy making influence.     

“Follow the Water”: Steve Squyres and the Mars Exploration Rovers

Steve Squyres was responsible for assembling the team of scientists, engineers and instruments that formed the Mars Exploration Rovers (MER). Squyres developed a vision that small-scale observations made by a robotic geologist on Mars would be the key for resolving the mystery of water on Mars. Prior to the MER missions, planetary scientists were divided between groups holding that ancient fluvial-like surface features on Mars were formed by water and those holding that the erosive and depositional forces were tied to liquid and gaseous CO₂. At issue was a fundamental understanding not only of early Martian geological processes and early solar luminosity, but also the possibility of life on Mars. To resolve these questions, Squyres and his team developed a new breed of rovers that were capable of identifying minerals and collecting textural observations. The resulting twin rovers, Opportunity and Spirit, have successfully resolved the single most important question about Mars that scientists have been debating for the past 30 years, providing compelling evidence for the action of water on the Martian surface. Squyres and the MER team have also initiated a new era in planetary exploration and inspired a new generation of students to become scientists and explorers. Steve Squyres and the MER team produced fundamental insights into the geology and climatology of Mars. These have resulted in major advances in our understanding of the potential for life on other planets and of life’s evolution on Earth. For the discovery and elucidation of water on Mars through the “robotic geologists” of the Mars Exploration Rovers, Steve Squyres was awarded the 2007 Benjamin Franklin Medal in Earth and Environmental Science.     

The trust continuum in the information age: a Canadian perspective

This paper examines the role of trust in the information continuum. It argues that in the context of Canadian federal government records, an analogous ??trust continuum?? is a useful model for analysing the relationships that exist between creator, archives and user in the information-abundant environment. The paper borrows from sociological theory to posit that creator, archives and user are bound together in a complex expert system that facilitates trust and mitigates risk in a broad societal context and contends that these interactions are shaped at the macro level by a dominant public discourse of accountability. These points are illustrated through three recent examples at Library and Archives Canada. First, the relationship between Canadian society and the archives is explored by interrogating the concept of relevance and assessing the feasibility of managing a pan-Canadian collection via a national network of knowledge institutions. Then, the role of trust between the archives and the creator in the management of government digital information resources is examined in light of the recently issued Directive on Recordkeeping, and in the context of LAC??s Trusted Digital Repository. Finally, Commissions of Inquiry??and the Indian Specific Claims Commission in particular??demonstrate both the power of archival records in repairing trust between a society and its government and the iterative nature of the relationship between the user and the archives.     

A review of the acculturation experiences of international students

Universities in Western countries host a substantial number of international students. These students bring a range of benefits to the host country and in return the students gain higher education. However, the choice to study overseas in Western countries may present many challenges for the international student including the experience of acculturative stress and difficulties with adjustment to the environment of the host country. The present paper provides a review of current acculturation models as applied to international students. Given that these models have typically been empirically tested on migrant and refugee populations only, the review aims to determine the extent to which these models characterise the acculturation experience of international students. Literature pertaining to salient variables from acculturation models was explored including acculturative stressors encountered frequently by international students (e.g., language barriers, educational difficulties, loneliness, discrimination, and practical problems associated with changing environments). Further discussed was the subsequent impact of social support and coping strategies on acculturative stress experienced by international students, and the psychological and sociocultural adaptation of this student group. This review found that the international student literature provides support for some aspects of the acculturation models discussed; however, further investigation of these models is needed to determine their accuracy in describing the acculturation of international students. Additionally, prominent acculturation models portray the host society as an important factor influencing international students’ acculturation, which suggests the need for future intervention.

Emotional responses to documentary viewing and the potential for transformative teaching

This paper examines the relationship between specific documentaries and white student teachers’ emotional responses to their viewing as part of a postgraduate teacher education course on educational equality. Documentaries are considered in terms of features (including elements of text), form (including stylistic conventions) and function in order to evaluate those elements most important in involving students emotionally. It argues that certain documentaries have the pedagogic potential to transform student thinking via the evocation of particular emotions which act to disturb white hegemonic practices, attitudes and cognitions. However, given that emotion is understood as integral to the operationalisation of whiteness, students’ emotional responses are analysed from a critical whiteness perspective to reveal emotion as also potentially obstructive to student transformation. Hence, the paper shares the pedagogic decisions taken to capitalise on those emotional responses conducive to transformed student understandings and to stymie those which act as investment in whiteness to impede student development. Finally, it is argued that a conceptual lens is vital for understanding the relationship between documentaries and emotional responses in order that transformed thinking is enabled.     

The role of feedback in e-assessments for engineering education

The aim of this investigation was to compare two differently designed e-assessments (formative assessments) which supported the same engineering courses for two academic years. In this investigation two group of students participated (Control Group: CG and Experimental Group: EG). The teachers followed exactly the same teaching approach using the same learning tools (apart from the e-assessments) in the same learning environment. The first group of students (CG) had the opportunity to timely receive grades along with the correct answers, when they submitted the e-assessments on-line. The teachers themselves designed these e-assessments in BlackBoard Vista© learning environment. The second group of students (EG) had the opportunity to receive feedback each on their own individual responses having unlimited attempts to participate in the e-assessments designed by PhD students. We will demonstrate that the addition of individual feedback and the unlimited attempts increased the EG group performance at the end of the courses (summative assessment) in comparison to the CG group of students.
