Abstract
|
|
|
The purpose of this study was to examine the 7th national science curriculum (chemistry domain)
regarding the meanings of ‘mulgil’ (Korean), the particulate nature of matter, and the state of matter. It was found
that the term of ‘mulgil’ was being used vaguely as representing material, matter, or substance without clear definition.
This was problematic by reason that it could hinder students from having the concept of substance. Regarding
the particulate nature of matter, molecule was introduced as a basic unit of matter at grade 7, prior to atom
and ion, which were introduced at grade 9 and 10, respectively. It is necessary to reconsider the sequence of each
particle concept to provide students with more consistent and comprehensive understanding of structure of matter.
In the case of change of state, key concepts such as conservation of matter or reversibility were omitted in the curriculum
document, and explanations based on various aspects of particles were somewhat insufficient. The concept
of matter is fundamental to chemistry, and we must recognize it as a concept that needs to be taught clearly. Implications
for curriculum revision were discussed.
