posted on 2021-11-01, 12:38 authored by Lajos Kovács, Gábor Betyár, Erzsébet KoromChemistry curricula in part rely
on the use of laboratory demonstrations
and experiments. The complex nature of this kind of educational activity
has been posing challenges from the very early days of teaching chemistry.
As chemistry is an experimental science, one possible approach to
make the teaching of this subject more efficient is to use materials
that students encounter in their everyday life. The present paper
delineates our efforts to create an integrated database of common
chemicals and their use in Hungarian elementary and middle schools.
The database combines two seemingly separate but intimately connected
fields which has not been accomplished so far: a database of common
chemicals and a database of chemistry laboratory demonstration experiments.
The two databases with their own idiosyncrasies are connected through
a common element, the components present in everyday chemicals. The
database offers various levels of searching in both subdatabases and
allows pre- and in-service teachers to design their own demonstrations
and student experiments, based on common chemicals, that best fit
their curricula in context-, project-, inquiry-, discovery-, and phenomenon-based
education. The application of our database allows the facilitation
of a conceptual change how chemistry and chemicals are contemplated
both in and outside school.
