The chemical bonding topic was covered in General Chemistry
course in 4 weeks (4 h per week) by using the guide materials.
Before the the study, a question – answer discussion session with
all students’ participation was held in order to eliminate misconceptions
about chemical bonding or to fill in the missing knowledge
on the topic. This preparation activity was practiced for two class
hours. The physical environment and all materials were provided by
the researcher during the classroom activities. Considering the
students’ academic achievement in general chemistry in the 2010-
2011 fall semester, by using the stratified random sampling method,
10 groups were formed with 4 students in each group. The groups
were informed about the guide material. During the implementation
of the guide material, all activities performed by the groups were
observed by the researcher and support was provided when
necessary.
