The term ‘Nature of Science’ (NOS) is often used to refer to distinctive
characteristics of scientific enterprise and qualities of scientists. An
adequate understanding of NOS is crucial for better decision-making and
a positive scientific attitude. Teachers are expected to develop this
understanding among their students for which they require an
understanding of various aspects of NOS (e.g. scientific knowledge is
tentative or science involves creativity). In addition, they need knowledge
of how learners’ misconceptions about NOS and scientists can be
challenged with the help of appropriate strategies. This knowledge base
of teachers is popularly referred to as ‘PCK for NOS’ (Pedagogical
Content Knowledge (PCK) for teaching NOS). This knowledge base is
complex. How far teachers possess it needs investigation. In the present
paper, the authors have provided a review of studies revealing the status
of teachers’ PCK for NOS. Firstly, teachers’ understanding of NOS is
discussed. Then, the status of science teaching in schools is reviewed.
Thereafter, studies specific to PCK for NOS are examined. The factors
that influence the teaching of science and NOS are also highlighted. The
review reveals that teachers do not understand some important aspects of
NOS and hold the stereotypical image of scientists. The teaching-learning
of science in schools is also not satisfactory and NOS is hardly addressed
in science classrooms. However, the intentions and practices of teachers
for teaching NOS evidently improve with interventions. Based on the
review, the paper concludes that the way science is presented in science
classrooms needs to be revisited. It is suggested that Teacher Education
Programmes must play their role in developing PCK for NOS among
teachers and suitable instruments must be developed for measuring PCK
for NOS.
