This study aims to create a Suggestion Reciprocal Learning (SuReL) with the aid of the Hypnoteaching model to develop students' social attitudes, self-confidence and mathematical problem-solving abilities that are valid and effective at Junior High School Tarutung, North Tapanuli. The method used in this research is research and development methodology with 5 stages of development by Plomp i.e. (1) initial assessment (define), (2) design, (3) realization (construction), (4) testing, evaluation and revision (develop), and (5) implementation (experiment) by considering three product quality criteria from Nieveen, such as validity, practicality, and effectiveness. This research and development resulted in several learning tools: (1) Suggestion Reciprocal Learning (SuReL) with the aid of the Hypnoteaching SuReL model, (2) Teacher and Student Handbooks, (3) Lesson Plans, (4) Syllabus, and (5) Student Worksheet. The results showed that the learning tools developed met valid criteria and could support the application of the SuReL model. The practicality level of the SuReL model using learning tools (Lesson Plans, Teacher Handbooks, Student Manuals, Student Worksheets and Learning Outcomes Tests) in the implementation of learning in class is in the high category. The effectiveness of the SuReL model can be concluded: (i) The acquisition value of students' social attitudes is 3.50, including in the very good category. (ii) The acquisition value of self-confidence is 2.77, including in the good category. (iii) the percentage of students who have a high level of mastery is 40% of 30 students. and (iv) student responses to the components and learning activities of the SuReL Model are positive.
