ABSTRACT
This research were aimed to: (1) determine the procedure development of chemical module for vocational based on contextual teaching and learning in redox reactions, (2) test the feasibility of chemical module for vocational based on contextual teaching and learning in redox reactions subject on 10th grade students, (3) know the effectiveness products of chemical module for vocational based on contextual teaching and learning on redox reactions subject on 10th grade students.
The module development research used the research and development procedure of Borg and Gall that had been modified into 9 stages: 1) research and information collecting, 2) planning, 3) develop preliminary from of product, 4) preliminary field testing, 5) main product revision, 6) main field testing, 7) operasional product revision, 8) operasional field testing, 9) final product revision. Analysis of the data were used qualitative descriptive analysis.
The result showed: (1) the development of chemical module for vocational based on contextual teaching and learning on redox reactions subject has been done throught R&D procedure that include nine stage, (2) the feasiblity of chemical module based contextual teaching and learning on redox reactions subject is fit as chemical learning, (3) the result of the effectiveness on cognitive , attitude and skill achievement aspect shows that experimental class is better than control class.
