摘要：The main purpose of the research was to study how problem based learning model affected students’ achievement, attidute and motivation in Chemistry Lesson the unit of “Mixtures”. In the study, semi-experimental design with pretest-posttest control group was used. The sample of the research was 52 students who were the 10th grade students in 2009-2010 academic year spring semester. The students were divided into two groups as treatment and control groups according to random sampling method.
