THE DEVELOPMENT OF PROBLEM-BASED APPLIED MICROBIOLOGY TEXTBOOK

The study was aimed to develop a problem-based applied microbiology textbook based on national standard.
Instructional materials such as books will guide students in carrying out learning activities in applied microbiology course. This research was conducted in Medan State University Graduate School in January-May 2014, with the development of a model consists of three phases: the analysis phase, which includes defining the front-end analysis, student analysis, material analysis, task analysis, and specification of learning objectives. Design phase, consists of: selection of media, selection of format, and initial planning. Stage of development, consist of supervisor assessment, validation of materials’ expert along with limited testing of learning design and final instruments. The products being produced was in form of a textbook used by third semester Master program students of Biology Education, Graduate School, State university of Medan. The developed Applied Microbiology textbook was considered feasible by the validation team. Results of expert team’s assessment showed the average of 90.30% a very feasible category and learning design experts rating this textbook 83.40%, categorizing it into feasible. Test of limited group by microbiology lecturer resulting in 91.30% which showed a very appropriate category, and from 40 students of fourth semester Biology Education Postgraduate Program, rating this textbook 83.39%, which this rate categorized into an "interesting" one.
