    Addressing challenges in assessing Human-Computer Interaction at scale

    No full text
    Human-Computer Interaction (HCI) is a research area which studies how people interact with computer systems. Because of its multidisciplinary nature, HCI modules often sit at unease within the computer science curriculum which is primarily composed by modules typically assessed through objective measures, using quantitative methods. Assessment criteria of HCI topics need to make some subjective measures quantifiable (e.g. aesthetics and creativity). In the case of large classes, it is critical that the assessment can scale appropriately without compromising on the validity of the judgment of how well the learning outcomes have been achieved.In the HCI module 'Interaction Design' at the University of Southampton, faced with increasing student numbers (from less than 80 to over 160 in two years), lecturers redesigned the assessment to provide timely feedback. The module is assessed by exam and coursework, where the exam includes a large section composed of multiple-choice questions (MCQs). In order to foster higher-order learning, students were encouraged to author MCQs using the platform PeerWise, which proved to be used as a revision aid towards the exam.In the coursework, students are required to conduct qualitative research, which in turns informs the creation of prototypes for technical solutions to problems from diverse areas of interest. Providing student such diversity of choices encourages creativity and freedom, as well as their application of the theoretical background of human-computer interaction.This presentation explains the authors' approach to assessment, both in supporting the creation of MCQs and exam revision, as well as in how the medium of video allowed for the expression of creativity and application of knowledge, whilst allowing for considerable ease of marking compared with traditional alternatives, which allowed for the provision of timely feedback to students

    Assessment design: video as an assessment tool

    The Interaction Design module for second year undergraduates in Computer Science and related disciplines at the University of Southampton has presented important challenges in assessment in recent times given two important constraints: firstly, the large increase in student numbers (from less than 80 in recent years to over 160 in 2016/17). Secondly, the fact that it is difficult to measure the intended learning outcomes of the module in a scalable manner.In particular, students are required to conduct qualitative research, which in turns informs the creation of prototypes for technical solutions to student-selected problems from diverse areas of interest. Providing students such diversity of choices encourages creativity and freedom of expression, as well as their application of the theoretical background of human-computer interaction.This presentation explains the authors’ approach to the main coursework assessment, and how the medium of video has allowed for the expression of creativity and application of knowledge, whilst allowing for considerable ease of marking compared with traditional alternatives. We were able to provide feedback on this work in a timely and comprehensive manner, which has been reported by students as beneficial

    Supporting authoring of multiple-choice questions in human-computer-interaction using PeerWise

    PeerWise is a web-based, free software that supports authoring, sharing, answering, evaluating and discussing multiple-choice questions (MCQ). Students can author questions, as well as answer and rate questions generated by their peers. In doing so, they can gain badges for reaching specific milestones related to their engagement (in authoring, answering, and commenting on questions). Lecturers can keep track of students’ participation. Aim: Can we support assessment in non-STEM subjects via student-authored MCQ software such as PeerWise? Observations: The majority of questions were authored and answered directly prior to the two participation deadlines; significant use of PeerWise as a tool for exam revision; minimum effort approach by some students brought down overall question quality; students felt there was a lack of moderation from facilitators of question quality; badges motivated some (but not all) students.Peer reviewe

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
