ab: Summary: The author here describes an exemplary grade-8 algebra lesson in
Hong Kong, taken from the data of the learners’ perspective study.
The analysis presents a juxtaposition of the researcher’s analysis of
the lesson with the teacher and students’ perspectives of the lesson.
The researcher’s perspective applies the theory of variation for
which the main concern of learning is the discernment of the key
aspects of the object of learning and that the description of
variations delineates the potential of the learning space. Some
persistent features were illustrated, namely, the teacher talk was a
major input in teaching; the technique of variation was used in the
design of the mathematical problems and the dimensions of variation
created in the class interaction provided a potential learning
environment; the teacher taking seriously the student factor into
account in his philosophy and practice. From the standpoint of
enculturation, the teacher’s influence as an enculturator is
intentional, significant and influential.
