Handbook for Learning-centred evaluation of Computer-facilitated learning projects in higher education

This handbook supports a project funded by the Australian Government Committee for University Teaching and Staff Development (CUTSD). The amended project title is “Staff Development in Evaluation of Technology-based Teaching Development Projects: An Action Inquiry Approach”. The project is hosted by Murdoch University on behalf of the Australasian Society for Computers in Learning in Tertiary Education (ASCILITE), as a consortium of 11 universities. The rationale of the project is to guide a group of university staff through the evaluation of a Computer-facilitated Learning (CFL1) project by a process of action inquiry and mentoring, supported by the practical and theoretical material contained in this handbook

From Diagnostic Feedback to University Policy

This seminar is co-organised by the Centre for Information Technology in Education (CITE) and Faculty of Education, HKU The starting point for this seminar will be that evaluation needs to move beyond isolated course evaluations, or evaluations of small components of courses. We need to understand students' 'whole' experience of the curriculum - on- and off-line, and across all courses of their programmes. At The Chinese University of Hong Kong, students in each undergraduate programme are surveyed on their perceptions of: a) how well their programme supports the development of important graduate capabilities, and b) aspects of the teaching and learning environment. This provides valuable input to departmental reflective processes. The survey has now been integrated into the University's quality assurance policy. This presentation argues strongly that quality assurance policies need to: be based on student experience, facilitate changes to teaching and learning which are practical and feed into specific strategies for designing learning environments, and have acceptance within the organization.Carmel McNaught is Professor of Learning Enhancement in the Centre for Learning Enhancement And Research (CLEAR) at The Chinese University of Hong Kong.

A historiography of the Elizabethan poor laws: late XIXth and XXth century historians

The Elizabethan poor laws stand as a great work from a dynamic period. How and why they were formulated have been questions which historians have asked for centuries. The discussions of these questions have varied, depending on the personal values and biases which each historian brought to this study. It is generally agreed that a very important function of the historian is interpretation. The study of history is not only a study of the events, but a study of the historians and their differing interpretations of those events. In the past one hundred years, numerous historians have devoted themselves to studying the Elizabethan poor laws. Their interpretations varied considerably in some areas and very little in others. This essay examines some of those interpretations and attempts to find methodological and/or ideological differences which may account for the differing opinions. The study focuses upon four broad schools of historical thought-Whigs, legal historiains, economic historians, and social historians. The historians selected represent a wide range of interpretations. James A . Froude, C. J. Ribton-Turner, and George Nicholls represent the Whig interpretation. William Holdsworth and G. R. Elton represent the legal interpretation. William J. Ashley, R. H. Tawney, and Peter Ramsey were selected as the economic historians. E. M.Leonard, B. Kirkman Gray, Sidney and Beatrice Webb, A. L. Rowse, and W. K . Jordan are the social historians. Whig historians saw the poor laws as part of a continuing constitutional development. They interpreted them as representing the inevitable forward progress of the English system of government. Legal historians were concerned with the formulation of the law and with the machinery provided for its administration. Their interpretations focused on the law itself and its position in the legal system as a whole. Economic historians examined the factors behind the law and the economic factors in particular which they believed led to its passage. Thus, their interpretations centered upon discussions of the significance of such topics as enclosure, inflation, urbanization, and vagrancy. Social historians offered interpretations of the Elizabethan poor laws designed to explore the structural relationship between social classes

Wetting and contact-line effects for spherical and cylindrical droplets on graphene layers: A comparative molecular-dynamics investigation

In Molecular Dynamics (MD) simulations, interactions between water molecules and graphitic surfaces are often modeled as a simple Lennard-Jones potential between oxygen and carbon atoms. A possible method for tuning this parameter consists of simulating a water nanodroplet on a flat graphitic surface, measuring the equilibrium contact angle, extrapolating it to the limit of a macroscopic droplet and finally matching this quantity to experimental results. Considering recent evidence demonstrating that the contact angle of water on a graphitic plane is much higher than what was previously reported, we estimate the oxygen-carbon interaction for the recent SPC/Fwwater model. Results indicate a value of about 0.2 kJ/mol, much lower than previous estimations. We then perform simulations of cylindrical water filaments on graphitic surfaces, in order to compare and correlate contact angles resulting from these two different systems. Results suggest that modified Young's equation does not describe the relation between contact angle and drop size in the case of extremely small systems and that contributions different from the one deriving from contact line tension should be taken into account.Comment: To be published on Physical Review E (http://pre.aps.org/

Mechanism of Molybdenum-Mediated Carbon Monoxide Deoxygenation and Coupling: Mono- and Dicarbyne Complexes Precede C–O Bond Cleavage and C–C Bond Formation

Deoxygenative coupling of CO to value-added C_(≥2) products is challenging and mechanistically poorly understood. Herein, we report a mechanistic investigation into the reductive coupling of CO, which provides new fundamental insights into a multielectron bond-breaking and bond-making transformation. In our studies, the formation of a bis(siloxycarbyne) complex precedes C–O bond cleavage. At −78 °C, over days, C–C coupling occurs without C–O cleavage. However, upon warming to 0 °C, C–O cleavage is observed from this bis(siloxycarbyne) complex. A siloxycarbyne/CO species undergoes C–O bond cleavage at lower temperatures, indicating that monosilylation, and a more electron-rich Mo center, favors deoxygenative pathways. From the bis(siloxycarbyne), isotopic labeling experiments and kinetics are consistent with a mechanism involving unimolecular silyl loss or C–O cleavage as rate-determining steps toward carbide formation. Reduction of Mo(IV) CO adducts of carbide and silylcarbyne species allowed for the spectroscopic detection of reduced silylcarbyne/CO and mixed silylcarbyne/siloxycarbyne complexes, respectively. Upon warming, both of these silylcarbynes undergo C–C bond formation, releasing silylated C_2O_1 fragments and demonstrating that the multiple bonded terminal Mo≡C moiety is an intermediate on the path to deoxygenated, C–C coupled products. The electronic structures of Mo carbide and carbyne species were investigated quantum mechanically. Overall, the present studies establish the elementary reactions steps by which CO is cleaved and coupled at a single metal site

An analysis of the relationship between the preferred cognitive learning style of field independence/field dependence and success in learning English as a second language among post-secondary Japanese students

The research analyzed the relationship between the preferred cognitive learning style of field independence/field dependence and success in learning English as a second language (ESL) among post-secondary Japanese students. The study provided a review of literature in the field and developed a methodology including identification of appropriate measurement instruments. The testing was done with students at Tokyo International University of American (TIUA) in Salem, Oregon, and the findings were used to make recommendations concerning field independence/field dependence (FIIFD) as it affects post-secondary Japanese ESL learners. Three tests were administered to the entire TIUA student body of 117 students. The first, the Group Embedded Figures Test (GEFT) was administered to measure field independence! field dependence. Two tests were administered to measure success in ESL. The Test of English as a Foreign Language (TOEFL) and the Comprehensive English Language Test (CELT) were both given to measure success in ESL. The differences between the pretest scores and post test scores were then compared to GEFT scores to determine the correlation of FI/FD and ESL success. Analysis of the testing indicated that for overall success in ESL, there does not seem to be a relationship with FI/FD. However, on specific skills, as measured by the subtests, there may be a relationship. Since results on the TOEFL and CELT were consistent with each other except for the listening subtest, it was further concluded that the two tests measure the same thing. In addition to the relationship of Fl/Fl) and ESL, certain demographic factors were also examined to determine their relationship to success in ESL. While there does not appear to be a significant relationship between ESL success and a student's choice of major, there may be a relationship with the demographic factors of age, gender, and previous experience with English

Implementing Archaeological Conservation During American Nation-Building Efforts

This thesis seeks to define best practices for implementing the conservation of archaeological sites as part of a broader system of cultural heritage protection within the framework of United States nation-building efforts. The ransacking of the Baghdad Museum, plus the widespread looting of the Iraq’s archaeological sites, makes it clear that measures for cultural property protection within the United States government military framework deserve a critical analysis. First, the importance of protecting cultural property during armed conflict will be examined from a historical and military perspective. Next, previous American nation building attempts are discussed to give a sense of the general circumstances within which conservation activities are to be conducted. Specifically, Iraq will be analyzed as a prime example of the necessity of cultural heritage protection and the damage that can be inflicted on archaeological heritage when such protection is not included as part of larger operational planning framework. Then, what the United States has done and is currently doing in response to the ratification of the Hague Convention and the destruction of cultural property in Iraq are explored. After that, internationally-accepted best practices of archaeological conservation are provided as a framework for evaluating current endeavors and planning those for the future. Finally, recommendations will be made on how the government, specifically the Department of Defense and the State Department, can institute measures for the conservation of archaeological heritage during the planning process of nation building operations
