students' views about tap water, physical states of water, pure water
and water molecule was gathered through a questionnaire administered to
groups of 10th year students, 12th year students and 3rd year students
at a teacher training college, prospective primary teachers. Students'
characterizations of tap water and interpretations of the familiar
events and observations described in some of the questions, as well as
of what they thought a water molecule was conveyed alternative
conceptions, some of which have been reported as being held by younger
students. Information was also gathered through the same questionnaire
administered to three groups of 10th year students, on various
occasions, after implementing a novel chemistry teaching strategy,
within the compulsory curriculum. The alternative conceptions
identified are discussed and implications for teaching, in general, and
for teacher training programmes, in particular, are suggested.
