2020
This research is a research and development that aims to determine the level of validity, practicality, and effectiveness of the results of the development of mathematics learning tools with a scaffolding-assisted problem-posing approach. The procedure for developing learning tools is done by adapting the 4-D model from (1) which consists of the steps of define, design, develop, and disseminate. The research subjects were 27 students of class VIII of SMP Negeri 1 Sindue in Donggala Regency. The results showed that the learning tools which included: lesson plans, student activity sheets, and learning outcome assessment instruments were in the very valid category, while the teacher's books and students' books were in the valid category; learning tools developed meet practical criteria because the ability of teachers to manage learning in both categories and the teacher's response to the use of learning tools is positive; learning tools are declared effective, because an increase in the character of students, student learning outcomes are completed classically; Student activities reach ideal criteria, and students respond positively to learning tools.
