摘要：Recently mathematics learning paradigm has changed from teacher-centered to student-centered. This study was conducted with the aims are to produce learning materials (lesson plan and student worksheet) using new paradigms in mathematics learning especially on geometry as well as to describe the quality of the learning materials. This study used 4-D method which consists of 4 stages:define, design,develop,and disseminate. The results showed that the new paradigms used are Problem Based Learning approach,Investigation approach,and Problem Solving approach which characterize by the use of problem as a learning resource. The material chosen is geometric curved sides that have a lot of problem’s exploration in everyday life. The resulted learning materials have been validated by experts until they appropriate for learning. The valid Lesson Plan and Student Worksheet should be tested in classroom to know their practicality and effectiveness.
