Abstract

Mathematics literacy is an individual capacity to formulate, to employ, and to interpret mathematicsin variouscontextsof daily life. This study is an R&D which aims to develop validand practical learning devices of  PBL with realistic-scientific approach and PISA-adaptedassessment in order to effectively improve mathematics literacy capability of  Junior HighSchool students. The learning devices includes: syllabus, lesson plans, student worksheet, studentbook,andPISA-adaptedtestof mathematics literacy. The development model followsthe Plomp model: initial investigation, design, construction, test, evaluation, and revision.The learning devices testing was done in grade VIII of  SMP N 5 Semarang of  academic year2013/2014 by using non-randomized pretest-posttest control group design. The result suggeststhat: the learning devices are considered valid by referring that the experts’ judgement consideredthat the learningdevicesareverygood.Thelearningdevicesareconsideredpracticalbyreferringthe positiveresponseof the students and teacher, as well as the teacher’s capabilityto organize learning was in high category. The learning is considered effective in improvingstudents’ mathematics literacy.
