Abstract
This generic qualitative study was aimed at enculturating, through a four staged intervention,
access students at Lerotholi Polytechnic in Maseru, Lesotho. The core purpose was to give
students an opportunity to practice using Discourses of science as the meaningful way of
learning. The intervention predetermined stages were named Conceptual Foundation,
Conceptual Initiation, Conceptual Formulation, and Conceptual Application. This two week
intervention introducing the concept of interaction of magnetic field patterns, was implemented
in 2002 and 2003 academic years. The design of the intervention was informed by sociocultural
theory and situated cognition. The basic tenet therefore in this study is that learning science is a
social phenomenon, it is situated and distributed across physical and social aspects. On the basis
of this position, this study adapted learning science as enculturation into community of practice.
Data collected in this study was analysed using a discourse analysis approach in which the main
tool comprised studying semiotic, activity, material, political, and sociocultural aspects (acronym
SAMPS) of a situation. Two aspects, activity and semiotic, were identified as being critical in
understanding meaning – making and therefore foregrounded.
The activity aspect of Discourse analysis highlighted emergent categories comprising each
predetermined stage. Activities identified in these emergent categories reveal students’ talk,
and/or practicing of Discourses of science, commencing from a level of talk that is dominated by
prior knowledge recollection. Then it becomes ventriloquation, gradually developing to higher
cognitive demand than mere recollection of prior knowledge. Lastly the activities show own talk
used to develop and express understanding of application. The semiotic aspect analysis
underlines the importance of the following issues during the process of introduction as well as
practicing of ways of engaging scientific Discourses; Communicative approaches and discourse
patterns, Practicing of Discourses of science, and Language of learning and teaching. Evidently,
construction of meaning is related to communicative approaches and discourse patterns that
students engage. The four communicative approaches identified, Statement – Answer –
Statement, Statement – Question – Statement, Explanation – Answer – Explanation, and
Explanation – Answer – Explanation lead to two discourse patterns that students engaged in
interpersonal communication; the surface and deep dialogue discourse patterns. Surface
Dialogue refers to a communication between two or more people engaging Statement – Accept –
iii
Statement or Explanation – Accept – Explanation approach. Deep Dialogue refers to an
interpersonal communication between two, or more, people engaging Statement – Question –
Statement or Explanation – Question – Explanation patterns. Though deep dialogue approach
occurred throughout the four stages of the intervention, it is observed that the occurrence
improved during the last two stages. Interestingly, during the Conceptual Initiation stage, deep
dialogue incidences were scarce. Arguably the classification of interpersonal talk is a pertinent
conclusion insofar as talking, coupled with other stuff Discourses, is taken as critical step in
enculturation.
When drawing conclusions about the effectiveness of the intervention, the following
considerations are important. Firstly, the core understanding of the practicing of Discourses of
science is that in any classroom members of the setting, students participate by practising
Discourses of a different, but aspired, community. Secondly, the proficiency of the language of
learning and teaching (LoLT) is a critical element, with enormous potential of contributing
negatively towards construction of meaning. Three important conclusions have been made in
relation to this study in general. Firstly, the strategy to enculturate access students, coming from
different backgrounds with different learning styles, has helped them to construct meaning of the
physics phenomenon. Secondly, Communicative approaches and discourse patterns, practising
of Discourses of science, and the language of learning and teaching enabled, and/or disabled,
students to use the language of science. Lastly, the intervention implemented in this study
proved to be beneficial in enhancing the sharing of meaning among students and, in general,
encouraging talk which otherwise would not have taken place.
