The design used in this study was a didactical design (Didactical Design Research). The study began with diagnostic tests conducted in the XII MIPA class of SMA Negeri 2 Sukabumi to obtain obstacles learning data. Next, the didactical design was developed which was equipped with the prediction of students' responses which were tested on 34 students of class A of SMA Negeri 2 Sukabumi. From the trial results analysis was carried out to compose a didactical design revised, then it was tested on 36 B grade students at SMA Negeri 2 Sukabumi. The method used in this research is the Research and Development (R&D) method and the data collection techniques carried out, namely written tests, interviews, and documentation. The results of this study obtained a didactic design that is equipped with a prediction of student responses arranged based on identified learning obstacles. Analysis of student responses during the didactical design implementation was used as a reference for making the next didactical design. Judging from the effectiveness of improvement that is effective as high, it can be concluded that the didactical design developed in this study can overcome learning obstacles in the algebraic function limit.} }
