Structured learning materials function as ground base for students to read and analyze topic related on deeper level. This succession in learning emerge as a problem in biotechnology course for bioremediation topic at Biology Education Department of Universitas Negeri Padang. Students had to read the latest research articles from national and international indexed journal. However, they had lacked basic concepts in the first place and coumpounded by English as languange barrier. This lead to problem of not achieving learning puporses. Thus, there was a need of structured basic concept learning materials of bioremediation. Bioremediation is a process of reducing organic and inorganic pollutants by organisms in the environment. Bioremediation is about real problems, therefore, learning materials of bioremediation will be integrated with Contextual Teaching and Learning (CTL) pedagogical model, to lead students achieve deep comprehension. This was educational Research and Develompment (R&D) using Plomp model which consists of three phases: preliminary research, development or prototyping, and assessment phase. Data gathered as qualitative and quantitave, through interview, questionnaire and paper based test to assess students' comprehension of bioremediation. Result of this research showed that learning materials of bioremediation were valid from content, layout and presentation, graphics, and linguistic; practical in use for students and lecturer as users; and effective to improve students comprehension of bioremediation. © Published under licence by IOP Publishing Ltd.
