Bernstein's (1996: 2000) typology of pedagogy as competence and performance pedagogic modalities provides a productive lens for the analysis of different modalities of educational technology pedagogy. The question addressed in this paper is why theories of learning and pedagogy have become conflated in educational technology literature. The paper illustrates that behavioural and cognitive psychologybased pedagogy corresponds to Bernstein's performance pedagogic modality and constructivist educational technology pedagogy corresponds to Bernstein's competence pedagogic modality. The paper shows how concepts, which surfaced initially in the discourse of psychology and particularly in learning theories, have been taken up and recontextualised. Furthermore the paper, using Bernstein's notion of the ‘social logic’ underlying pedagogies, demonstrates why learning theories, particularly that of cognitive constructivism, have appealed to pedagogic constructivists and come to dominate educational technology researc...

This paper describes a research project that was undertaken to explore the impact of a textbook, Maths for all, in primary mathematics classrooms. A quasi-experimental design was used, and a random sample of 14 classrooms from ex-DET primary schools in Cape Town was selected, 10 of which were given class sets of the textbook at the start of the project, and 4 were given these sets only after the project was completed. Data from interviews, questionnaires, classroom observation and pre-and post-tests were collected. An analysis of aspects of the textbook was undertaken, and of its use by teachers in classrooms. It is argued that the inductive style prioritised by the textbook is in tension with the preferred deductive style of most of the teachers, resulting in the fragmenting of its semantic structure. Statistical analysis of pre- and post-tests revealed no educationally significant differences between students with access to the textbook and those without access. The majority of learners (n=538) ...
