Abstract
This research is a learning tool development research that aims to: (1) describe the development process and produce learning tools that are valid, practical, and effective in learning Problem-Based Number Theory- (2) to find out whether Problem-Based learning in number theory learning can improve student lecture results. This device was developed using Four D (Define, Design, Develop, and Disseminate). The trial of the development of this device was carried out in the S1 Mathematics Education Study program in number theory lectures. The purpose of developing this lecture tool can be to produce a Number Theory lecture tool: a Number Theory Textbook, and 14 Valid, Practical and Effective Lecture Event Units (SAP).
The implementation process is carried out by preparing the teaching material components of the Number Theory course that will be produced in the form of: textbooks, Lecture Event Units (SAP) which can be applied to the Number Theory course in 2022. In the implementation of dissemination by applying limited Number Theory teaching materials will produce: textbooks, Lecture Event Units (SAP) as many as 14 valid, practical and effective meetings to the Lecturer Team in the Department of Mathematics FMIPA Unimed.
Keywords: Development of learning tools, validity, practicality, and effectiveness
