Senior high school grade A student alternative ideas on the formation and properties of molecules.
Summary:
In the present study are reported the results of a survey on a group of 1613
students of grades B and C of senior high schools during the 2010-2011 school
year. The aim of the study was to investigate, through questionnaires, the
chemical knowledge acquired by the students and the existing misconceptions
related to a group of aspects on molecules, chemical bonding and properties of
chemical compounds, which are taught at senior high school grade A.
The survey was carried out on a wide group of students regarding the schools
they attend in order to have an as adequate as possible body of resulting
questionnaires representative of their distribution all over the country. In
the schools included in the study there are high schools of big and small
cities, in rural areas, both public and private, experimental schools under
university supervision as well as some “special schools” including musical,
intercultural and ecclesiastical.
According to our findings the students are facing severe problems in
understanding the main facts related to the molecule and the chemical bond. The
main difficulties identified in the understanding of the formation of molecules
and the type of bond between atoms and the phenomenon of dissolution of a
substance.
