mathematical meaning from the words into the symbolic representation; there are
different (equally correct) ways in which the meaning can be expressed; all correct
ways of expressing this meaning will result in the same correct solution; the grounds
for making decisions and legitimating a text (in this case, a particular expression) as
correct are to be found in the mathematical meaning itself. All legitimating appeals
are to the domain of mathematics.
This is accomplished within a discussion-based pedagogic practice, where discussion
moves between lecturer directed whole class discussion (where students can and
do punctuate the flow), as well as small group discussion amongst students. The
general pattern of interaction points, in Bernstein's terms, to weak internal framing
with respect to social relations and pedagogy. The internal framing with respect to
sequencing is also weakened. This is illuminated in the sequence of sub-events from
E1.4 to E1.5 leading to the move to Event 2.
Throughout E1.1 to 1.4 the focus was on the mathematics involved in solving the word
problem. After E1.4 there is a shift in focus which signals the beginning of a new event, E2.
The lecturer draws the attention of the students towards listening for differences in the way
students express their understanding, and the need for teachers to do this. This is a teaching
object rather than a mathematical object.
