Abstract
This Research’s purpose is producing questions/case study in direct proportion topic focused on Map and Model, and analyse students’ answer in solving these arranged questions through lesson study for learning community (LSLC) and PMRI approach using problem based learning (PBL) method. Research subject are students of grade VII of Junior High School 1 Palembang. From this research, it results a LKPD questions about direct proportion in Map and Model that consist of three cases, such as determine new scale from known scale in problem solving (C2), determine size of Limas House miniature from known scale and sizes in problem solving (C3), and check for errors from a given comparison in problem solving (C4). Based on the results of the analysis of Students answer small group, the average score obtained by students in problem 1 (sharing task) is 73.5, problem 2 (sharing task) average student score is 55, and average student score in problem 3 (jumping task) is 48.5. So these three problems are well-billed and can be used to the next stage of the field test.
Highlights
Students mostly looked at mathematics such with negative perception such as mathematics is a science with full of symbols and formulas which make students often confuse so that subject gives an unhappy experience of learning (Widyastuti, et al, 2019)
Material about direct proportion is one of the material felt difficult by students due lack of understanding how to apply it in the form of case study questions (Suwarni, 2017)
Map and model topic is one part of direct proportion material in mathematics related to all activities of counting in fractions, geometry, congruence, etc. (Dole, et al, 2009; Utari, et al, 2015)
Summary
Students mostly looked at mathematics such with negative perception such as mathematics is a science with full of symbols and formulas which make students often confuse so that subject gives an unhappy experience of learning (Widyastuti, et al, 2019). Students is lack of being pushed to improve their thinking ability in learning process and students did given directions to use and memorize formulas (Hasanah, et al, 2019). Those problem make this subject as terrifying subject for students and make their less attention and curiosity of it (Patahuddin, et al.,2009). (Dole, et al, 2009; Utari, et al, 2015). Sclae is relative comparison between object and proportion is relationship of size and scale in a composition (Dole, et al, 2009)
