Abstract

The objective of this study is to find out the effect of industrial microbiology problem based textbook application on students problem solving skills. A quasi experimental research with pretestposttest control group design was used in this study. The population of this study was 6th semester students of Biology department and 2 classes chosen as the sample by applying cluster random sampling technique. Experimental class was using industrial microbiology problem based textbook while control class was using conventional textbook. The instrument used to obtain the data was description test. The data were analyzed by using Mann-Whitney U-test. The ranked test scores of the two books were significantly different (U = 89.5, n1 = 21, n2 = 21, p < 0.05). z = -3.296 < -1.96 means the null hypothesis was rejected, suggesting that there is an effect of industrial microbiology problem based textbook application on students problem solving skills. The sum of ranks for industrial microbiology problem based textbook (Σ R1 = 582.5) was larger than the sum of ranks for conventional textbook (Σ R2 = 320.5). Therefore, it can be stated that industrial microbiology problem based textbook as a more effective textbook for problem solving skills of students.
