The Automatic Assessment of Multiple Artefacts: An Investigation into Design Diagrams and Their Implementations
As the Higher Education sector has moved towards student-centred learning so too has the growth in electronic support for learning. E-assessment has been a part of this growth as increasingly assessment and its feedback is seen as an integral part of the studentsâ learning process. Mature e-assessment systems exist, particularly where answers to questions are restricted to a prescribed list of alternatives. However, for free response artefacts, where there is a limited restriction placed on answers to questions, automated assessment systems are embryonic.
This dissertation presents an investigation into the automated assessment of free response artefacts. Design diagrams and their accompanying source code implementations are examples of free response artefacts. A case study is developed that investigates how to automatically generate formative feedback for a design diagram by utilizing its accompanying implementation. The dissertation presents a two-staged solution, initially analysing the design diagram in isolation before comparing it with the implementation. A framework for this approach has been developed and tested using a tool applied to coursework submitted by undergraduate computer science students.
The tool was evaluated by comparing the formative feedback comments generated by the tool with those produced by a team of computer science educators. Evaluation was undertaken via two Likert questionnaires, one completed by students and one completed by a team of computer scientists. The results presented are favourable, with the majority of comments produced by the tool being seen to be as least as good as those generated by the computer science educators
Occlusions of the Operational Sequence: a coincidental conversation between Robert Matthew and André Leroi-Gourhan in six diagrams
In the 1960s, with western narratives of technical progress at their height, Robert Matthew, then president of the Royal Institute of British Architects, and anthropologist AndrĂ© Leroi-Gourhan independently advocated totalising, systematic and technical models of human progress. Each model a reflection of the aims and methods of their own discipline: for the anthropologist, the evolution ofHomo sapiensfromHomo faberand the dissolving of human/technological boundaries; for the architect, a âcollective welfare-socialismâ and the systematisation of its built manifestations. Each of these models made manifest, I argue, through profoundly influential diagrams. Leroi-GourhanâschaĂźne opĂ©ratoiredescribes the manufacture of pre-historic stone tools, whilst the RIBAâs Plan of Work describes the design and construction of buildings. Through the embodied objects and processes of these diagrams this paper sees âchaĂźneâ and âPlanâ engaging in a kind of reciprocating exchange: a diagrammed conversation revealing, for each discipline, processes occluded or overlooked in the other
Visualizing Set Relations and Cardinalities Using Venn and Euler Diagrams
In medicine, genetics, criminology and various other areas, Venn and Euler diagrams are used to visualize data set relations and their cardinalities. The data sets are represented by closed curves and the data set relationships are depicted by the overlaps between these curves. Both the sets and their intersections are easily visible as the closed curves are preattentively processed and form common regions that have a strong perceptual grouping effect. Besides set relations such as intersection, containment and disjointness, the cardinality of the sets and their intersections can also be depicted in the same diagram (referred to as area-proportional) through the size of the curves and their overlaps. Size is a preattentive feature and so similarities, differences and trends are easily identified. Thus, such diagrams facilitate data analysis and reasoning about the sets. However, drawing these diagrams manually is difficult, often impossible, and current automatic drawing methods do not always produce appropriate diagrams.
This dissertation presents novel automatic drawing methods for different types of Euler diagrams and a user study of how such diagrams can help probabilistic judgement. The main drawing algorithms are: eulerForce, which uses a force-directed approach to lay out Euler diagrams; eulerAPE, which draws area-proportional Venn diagrams with ellipses. The user study evaluated the effectiveness of area- proportional Euler diagrams, glyph representations, Euler diagrams with glyphs and text+visualization formats for Bayesian reasoning, and a method eulerGlyphs was devised to automatically and accurately draw the assessed visualizations for any Bayesian problem. Additionally, analytic algorithms that instantaneously compute the overlapping areas of three general intersecting ellipses are provided, together with an evaluation of the effectiveness of ellipses in drawing accurate area-proportional Venn diagrams for 3-set data and the characteristics of the data that can be depicted accurately with ellipses
Graphic design as urban design: towards a theory for analysing graphic objects in urban environments
This thesis presents a model for analysing the graphic object as urban object, by
considering atypical fields of discourse that contribute to the formation of the
object domain. The question: what is graphic design as urban design? directs
the research through an epistemological design study comprising: an
interrogation of graphic design studio practice and the articulation of graphic
design research questions; a review and subsequent development of research
strategy, design and method towards the articulation of methodology that reflects
the nature of the inquiry; a detailed analysis of five different ways to study and
research graphic design as urban design, in geography, language, visual
communication, art and design, and urban design. The outcome of the
investigation is a model that enables future research in the urban environment to
benefit from micro-meso-macrographic analysis.
The model endeavours to provide a way to evaluate, design and enhance âpublic
places and urban spacesâ (Carmona et al., 2010) by considering different scales of
symbolic thought and deed. This has been achieved by acknowledging the
relationship between the relatively miniscule detail of graphic symbolism, the
point at which this becomes visible through increased scale, and the instances
when it dominates the urban realm. Examples are considered that show
differences between, for example, the size and spacing of letter shapes on a
pedestrian sign, compared to the âvisualâ impact of an iconic building in the
cityscape. In between is a myriad of graphic elements that are experienced and
designed by many different professional disciplines and occupations. These are
evidenced and explained.
Throughout the study an indiscriminating literature review is interwoven with
the text, accompanied by tabular information, and visual data in the form of
photographs and diagrams. This is mainly research-driven data utilising
photographs from fieldwork in Brazil, Canada, Hong Kong, Italy, Portugal, South
Korea, United Kingdom, and United States of America. The methodology
integrates a transdisciplinary adaptive theory approach derived from sociological
research, with graphic method (utilising a wider scope of visual data usually
associated with graph theory). The following images provide sixteen examples of
artefacts representing the graphic object as urban object phenomenon
