In day-to-day interactional discourse, disturbances in coherence can usually be resolved relatively quickly through collaboration and negotiation between interlocutors. When speakers are required to produce extended discourse in the form of an extended turn (i.e. short monologue), however, there is an additional requirement to package their utterances that the interlocutor can integrate them into the on-going discourse and construct a meaningful, coherent representation of the text. For non-native speakers, this additional burden means that any miscues in the construction of the utterances or in their contextualisation, can lead to disturbances in coherence and a loss of meaning.

Cette recherche porte sur la réalisation linguistique de l’explication en anglais contemporain. À la suite d’un travail définitoire de la notion sont identifiés deux types d’explication: la clarification et l’explication causale. L’étude adopte une approche énonciative tout en offrant des considérations d’ordre pragmatique. L’analyse linguistique se fonde sur un corpus de textes didactiques et examine plus particulièrement le rôle des connecteurs dans le discours explicatif. Enfin, ce travail vise également la formalisation de quelques relations discursives à l’œuvre dans l’explication et l’écriture de règles linguistiques en vue de la reconnaissance automatique de ces relations. / This study is concerned with the linguistic realisation of explanation in contemporary English. After a definitional work on the notion, two types of explanation are identified: clarifying explanation and causal explanation. The study adopts an utterer-centered approach while also considering pragmatic aspects. The linguistic analysis is based on a corpus of didactic texts and it focuses on the role played by connectives in explanatory discourse. Finally, the study also aims at formalising some discourse relations involved in explanations and designing linguistic rules in order to automatically identify the discourse relations at stake.

Increasing involvement with students at the University of Namibia has indicated their overall difficulty with comprehending and recalling information from oral content lectures. It has also been observed that in general very little attention is given to the development of listening skills in L2 ESP and EAP courses. For this study, I conducted a quasi-experiment to determine whether the recognition and interpretation of discourse markers will enhance students' listening comprehension in academic lectures. Students were tested to determine their comprehension of content information in a video-taped lecture. Qualitative data were collected by means of a questionnaire. After an intervention period of eight weeks, where the experimental group received strategy training in the recognition and interpretation of discourse markers in spoken texts, both groups were again tested. Their results were statistically compared. I also looked at related findings of other researchers. Finally, aspects for possible future research will also be considered. / English Studies / MA - (Specialisation in TESOL)
