<![CDATA[Abstract Experimental studies have conducted problem based learning model with multirepresentation appoach for seeing the increase of learning achievement and scientific consistency. Research was implemented at one of senior high school in West Bandung. Multirepresentation approach (verbal, graph and math) that believed that able to make easier the students for learning concept in various representation. Pre-experiment method is used with one group pretest and posttest design. Research sample was one of tenth grade classes. The instrument to measure the learning achievement is in the form of multiple choice question which consist of twenty six questions, while scientific consistency was measured by multirepresentative three tier test based 21 questions which consist of seven concepts. These is an improvement between pretest and posttest result, it is categorized as medium with gain normalization of learning achievement 0,44 while gain normalization of scientific consistency 0,38. Futher, there is improvement scientific consistency level for whole elastic subject, four students in the consistency level, 13 students in enough consistency level and four students in the not consistency level. Based on the research result, there is tendency in multirepretation answers with students’ multi intelegences level. Keywords: PBM with multirepresentation approach, learning achievement, scientific consistency Abstrak Telah dilakukan penerapan model pembelajaran berbasis masalah dengan pendekatan multirepresentasi untuk melihat peningkatan prestasi belajar dan konsistensi ilmiah. Penelitian dilaksanakan di salah satu SMA Negeri di Kabupaten Bandung Barat. Pendekatan multirepresentasi (verbal, gambar dan matematis) yang diyakini dapat memudahkan siswa mempelajari konsep dalam berbagai representasi. Metode yang digunakan adalah pre-eksperimental dengan desain one group pretest and posttest design. Sampel penelitian adalah satu kelas X. Instrumen untuk mengukur prestasi belajar berupa multiple choice test sebanyak 26 soal sedangkan konsistensi ilmiah diukur dengan menggunakan three tier test berbasis multirepresentatif sebanyak 21 soal terdiri dari 7 konsep. Terjadi peningkatan antara hasil pretes dan postes, yaitu berada pada ketegori sedang dengan gain prestasi belajar 0,44 sedangkan gain konsistensi ilmiah 0,38. Selain itu, terjadi peningkatan level konsistensi ilmiah untuk keseluruhan materi elastistisitas, yaitu 4 siswa berada pada level konsisten, 13 siswa cukup konsisten dan 4 siswa tidak konsisten. Berdasarkan hasil penelitian, terdapat kecenderungan jawaban multirepresentasi siswa dengan kecerdasan majemuk. Kata-kata kunci: PBM dengan pendekatan multirepresentatif, prestasi belajar, konsistensi ilmiah berbasis]]>
