摘要：This paper is the result of first phase of the research about the development of studentsâ€™Â mathematical understanding and representation ability through Joyful Problem-based LearningÂ (JPBL) at Public Junior High School in North Sumatera, Indonesia.The population is all of theÂ students of public junior high school (PJHS) in North Sumatera.Samples choose based onÂ stratified random sampling.The samples are the students of PJHS 27 Medan, PJHS 1 PercutÂ Sei Tuan, PJHS 1 Tebing Tinggi, and PJHS 2 Pematangsiantar.The techniques used forÂ collecting data is observation, interview, and essay test.The research findings: (1) Based onÂ interview and observation found that conventional approach still use in all of the class of PJHS;Â The students engagement in learning activity is very low as well as students self-regulatedÂ learning; Most of the students do not attain minimal mastery achievement, (2) Based on essayÂ test found that achievement of the students in mathematical understanding and representationÂ test is categories low.
