Impact of interaction technique in interactive data visualisations
This paper presents an analysis of different interaction techniques used in interactive data visualisations to support end-users in visual analytics tasks. Our selection of interaction techniques is based on prior work and consists of the interaction techniques Select , Explore , Reconfigure , Encode , Filter , Abstract/Elaborate , and Connect . Through a within-subject study, we assessed participants’ abilities to utilise these techniques when f…
Perspectives on peer-review
Drawing on eight years of observation and correspondence from the Aropä project, we report on the issues important to academics who conduct on-line student peer-review activities, and the features they request to support their own instructional designs. The Aropä project is unusually broad, having so far supported over 100 instructors at 20 institutions across nine countries, almost one thousand activities, and more than 36,000 individual student…
Peer-review in practice
Articles discussing and analysing student peer-review activities proliferate the educational literature, typically describing one or more class exercises where students provide feedback on each other’s work. These papers usually focus on a peer-review activity designed as a scholarly study, and make conclusions about its success or otherwise. There is not one standard model for ‘peer-review’, and information on the many different assessment desig…
A comparison of peer and tutor feedback
We report on a study comparing peer feedback with feedback written by tutors on a large, undergraduate software engineering programming class. Feedback generated by peers is generally held to be of lower quality to feedback from experienced tutors, and this study sought to explore the extent and nature of this difference. We looked at how seriously peers undertook the reviewing task, differences in the level of detail in feedback comments and dif…
Learning about Interface Design through Peer Assessment
Peer assessment is recognised as a useful learning activity, not merely as a means by which assignments can be marked. In a design subject such as Human-computer Interaction, peer-assessment offers a unique opportunity for students to be exposed to a wide range of different designs in an environment that ensures that they reflect on these designs. However, it is important that the marking criteria are well specified and unambiguous. This paper re…
A semiotic definition of multimedia communication
L'A. propose un cadre terminologique et theorique permettant de communiquer sur les systemes multimedia. Ce cadre est base sur les classifications semiotiques traditionnelles de la communication et integre differentes methodes syntaxiques, en considerant les modalites visuelles et auditives. De plus, ce cadre prend en compte la nature differente des procedes de communication, ce qui permet de definir le multimedia par rapport aux systemes represe…
