Conclusions and implications
Lederman (2007, 869) makes the following generalisations from the research literature
in relation to NOS: neither school students nor their teachers typically ‘possess
“adequate” conceptions of NOS’; such conceptions are ‘best learned through explicit,
reflective instruction as opposed to implicitly through experiences with simply
“doing” science’; ‘teachers’ conceptions of NOS are not automatically and necessarily
translated into classroom practice’ and ‘teachers do not regard NOS as an
instructional outcome of equal status with that of “traditional” subject matter outcomes’.
What this makes very clear is that work on developments in NOS is hard.
There also needs to be a sense of realism about what can be achieved on one year
ITE courses, given the nature of the education such science students have had previously.
In this sense, some of the lack of progress is not surprising. However, this
research does provide some pointers for future course development in our specific
context which would seem to be of importance more generally.
On the positive side, in our context the student teachers are arriving with
less naïve views of NOS than indicated by some other research reports. There is
also some evidence that specific parts of the course are starting to impact on
the students. Thus the PUS assignment was highly valued by some students and
cited as impacting on their thinking and the new sessions were felt to be relevant
and important in terms of teaching and learning. However, overall the
research shows a need to continue to develop the focus on NOS on the course.
In terms of the overarching research the data gives some rationale for the following
developments:
