1.Introduction
The course “Chemistry” is an applied course in which theoretical information is verified by experiments in
laboratories including scientific processing skills, acquirements of chemistry-technology-society-nature,
communication-attitude and value interactions besides critical thinking skills and life-long learning (Ayas et al.,
1997; Yıldız et al., 2006; TTKB, 2007). Since new information in chemistry instruction is widened continuously in
recent years, making students skillful in accessing information should be the primary aim instead of giving them
information itself. Hence, rather than making them memorize the content, students should be equipped with problem
solving skills for new situations they face, their information accessing and information producing skills should be
well developed as well (Gedik, Ertepınar & Geban, 2002).
1.1. Problem Statement
Laboratory applications are complementary of chemistry instruction and they are major parts of chemistry
lessons. Laboratories are crucial for making abstract chemistry conceptions concrete and making them
