- This study aimed was to describe the prototype teaching mathematics in improving critical thinking ability using problem based learning (PBL) for senior high school students. Researchers develop tools that include: (1) define (2) design (3) develop and (4) disseminate. The results of the definition phase is used to design a learning device, then draft the design is validated and tested to the students to see its effectiveness. The test device and dissemination limited classes used research subjects of students in Grade X SMAN 1 Percutseituan, Deli Serdang District, North Sumatera, Indonesia. The device was developed Learning Implementation Plan, Teacher’s Book, Student’s Bookˏ Students Worksheets, and Study Achievement Test. The results of the implementation of the learning development that the device was valid, practical, and effective, which is characterized by (a) teaching materials developed met the content and construct validity (b) teaching materials developed easy for teachers and students to carry and fit for purpose and (c) learning outcomes of students after getting the learning-based teaching materials complete PBL approach. In conclusion (1) the prototype teaching mathematics in improving critical thinking ability using PBL for senior high school students produced practical devices (2) mathematics learning using PBL model is effective.
