In the study, it was aimed to examine perception level of problem solving skills of teacher candidates participating in problem solving applications in chemistry laboratory and the effect of these applications on their perception of problem solving skills. Also it has been examined whether there is a significant relationship between perception of problem solving skills of teacher candidates and science process skills and logical thinking abilities. 72 teacher candidates participated in the study. In the study, perception inventory of problem solving skill, science process skill and logical thinking ability tests have been used as data collection tools. At the end of the statistical analyses, it was determined that teacher candidates perceive their problem solving skills good after realized applications and these applications are significant effect on their perception of problem solving skills. Also a correlation was determined between teacher candidates' perception of problem solving skills and science process skills and logical thinking abilities.
