Jonassen (2003) defines problem solving as an individual thought process because the previously learned law
can be applied in solving problems in any situations. It is also deemed to be a new type of learning and is the
result of application of knowledge and procedures of the problems (Mc Gregor, 2007). Generally, each individual
requires knowledge and skills to solve problems (Taconis et al., 2000). Halakova and Proksa (2007) stated that
the solution of problems in any subject area is a highly complex human behaviour. This matter is documented in
a large number of studies and articles which have appeared in journals of research and teaching. It has reflected a
new interest regarding how students solve problems. Problem solving has always been a stumbling block for
students who are studying chemistry, and most of the teachers in the field of chemistry are aware of this.
