On the understanding of computer network protocols

Abstract [en]

How students learn about network protocols is studied in a project-centred, internationally distributed, university course in computer systems taught jointly by two universities. Insights into students' understanding of basic concepts within computer networks are gained through an empirical phenomenographic research approach.

The use of phenomenography as a research approach makes it possible to learn about computer science, as it is experienced by the students. The context in which the research is carried out and issues concerning by whom the context is experienced, are investigated and form a part of the methodological basis.

Students' understanding of some protocols that are used within the project, as well as their experience of the general concept of network protocols are investigated, and different ways of experiencing the protocols are discerned. Some aspects that indicate good learning outcomes are identified, such as being capable of understanding a protocol in different ways and of making relevant choices between the ways it could be experienced according to the context in which it appears.

Based on these results a discussion on learning and teaching is developed. It is argued that a variation in the context in which the protocol is experienced promotes good learning, since different ways of experiencing a protocol are useful with different tasks to hand. A student with a good understanding of network protocols can choose in a situationally relevant way between different ways of experiencing a protocol.

Abstract [en]

Starting from an empirical study of lay adults' understanding of heatand temperature, we distinguish between different meanings of "context" inphenomenographic research. To confuse the variation in ways of experiencingthe context(s) of the study with the variation in ways of experiencing thephenomenon of study is to risk losing fundamental insights. We discuss contextas experienced and as interwoven with the experience of the phenomenon, andanalyse its significance in two dimensions: (1) the stage of the research project:formulating the question, collecting data, analysing data and deploying results;and (2) "who is experiencing" the context: the individual, the collective, or theresearcher. The arguments are illustrated from the empirical study.
