Constructing student’s scientific literacy is still a challenge for the developing country. PISA 2015 report on scientific literacy showed that Indonesia was positioned at 62th out of 70 countries. According to this result, the students are only able to explain the simple science phenomenon because some learning activities have not followed good scientific inquiry as a fundamental aspect of the nature of science. To overcome the problem, PISA 2015 stated that teachers are suggested to design well-structured laboratory activities that make actual scientific concepts and ideas, and help students make the connection among the hands-on activities, scientific ideas and real-life problems. Moreover, the student’s conception of the nature of scientific knowledge is required to help a student become a scientifically literate person. This work aims to construct science knowledge and contextual problems to support students’ conception of the nature of science. In the case of the physics subject, eight new heat and temperature experiment designs are proposed to construct students’ scientific literacy in high schools. The aspects of scientific literacy on experiment designs are developed based on PISA 2015 frameworks.

Penelitian dilakukan di salah satu sekolah swasta di Kabupaten Bandung dengan jumlah siswa kelas XI sebanyak 20 siswa. Penelitian bertujuan untuk mengetahui bagaimana penerapan metode Blended Learning ’ s station rotation untuk meningkatkan hasil belajar siswa pada materi tekanan hidrostatis. Metode penelitian ini menggunakan Pre-testing adalah metode penelitian yang digunakan untuk mengetahui pengaruh variabilitas terhadap variabel lain tanpa adanya variabel kontrol. Nilai N-gain menunjukan peningkatan hasil belajar siswa antara sebelum dan setelah penerapan metode Blended Learning ’s station rotation pada materi tekanan hidrostatis. Hanya unit eksperimen tanpa unit kawalan digunakan dalam kajian ini. Pengumpulan data penelitian dilakukan dengan menggunakan alat pre-post, menghasilkan N-Gain sebesar 0,54, kelas menengah.

This study aims to obtain a comparative picture of increasing conceptual understanding between students who experience problem-based learning with a multi-representation approach and students who experience problem-based learning without a multi-representation approach. The aspects of understanding studied refer to Bloom's taxonomy, namely translation, interpretation, and extrapolation. This study used a quasi-experimental method with pre test and post test design non equivalent group design. The sample in this study were students from two class X in one high school in the city of Bandung. The experimental class consisted of 28 students and the control class consisted of 25 students. The results showed that the students' understanding of the concept increased with an average n-gain in the experimental class and control class respectively, namely 0.406 with the medium category and 0.289 with the low category. Keywords: multi representation approach, problem based learning, conceptual understanding ABSTRAK. Penelitian ini bertujuan untuk mendapat gambaran perbandingan peningkatan pemahaman konsep antara siswa yang mengalami pembelajaran berbasis masalah dengan  pendekatan multirepresentasi dan siswa yang mengalami pembelajaran berbasis masalah tanpa pendekatan multirepresentasi. Adapun aspek pemahaman yang diteliti merujuk pada taksonomi Bloom, yakni translasi, interpretasi, dan ekstrapolasi. Penelitian ini menggunakan metode kuasi eksperimen dengan desain pre test and post test non equivalent group design. Sampel pada penelitian ini adalah siswa dari dua kelas X di salah satu SMA di kota Bandung. Kelas eksperimen terdiri dari 28 siswa dan kelas kontrol terdiri dari 25 siswa. Hasil penelitian menunjukkan bahwa pemahaman konsep siswa meningkat dengan rata-rata n-gain pada kelas eksperimen dan kelas kontrol masing-masing yaitu sebesar 0,406 dengan kategori sedang dan 0,289 dengan kategori rendah.Kata kunci: pendekatan multirepresentasi, pembelajaran berbasis masalah pemahaman konsep
