This research aims to describe the valid, practical and effective learning instrument based on the scientific learning that has been developed and produce learning instrument for developing valid learning instrument based on a scientific learning to improve mathematical problem solving ability and self-regulated learning at MTs Sinar Islami Bingai. This research is a development research. The development model used is the 4-D model which consists of four stages: define, design, develop and disseminate. The research subject is a learning instrument of the discussion of one variable linear equations and inequalities. The development testing was carried out on class VII of MTs Sinar Islami Bingai. The first development testing is carried out in class VII-2 and The second development testing is carried out in class VII-1 MTs Sinar Islami Bingai. The results of obtained development are: (1) Learning instrument developed were valid; (2) The learning instrument developed practically were indicated by responses of validator who said that learning instrument could be used with little revision or without revision; (3) Effective learning instrument were indicated by classical student learning completeness that has been achieved, positive student response to the components of learning instrument and learning activities developed, and the ability of teachers to manage learning obtain an average good category score. Increased self-regulated learning reached an average of 79.09 in the first development testing and 82.35 in the second one.
