This paper is aimed to discuss about design of STEM-based science learning in junior high school in the 2013 curriculum, and use the model of Project Based Learning (PjBL). STEM is an teaching and learning approach that integrates science, technology, engineering, and mathematics to reach the 21st century skills which is proclaimed in 2013 curriculum. In this paper only discuss one of teaching and learning model that supports and appropriate with the STEM approach namely the Project Based Learning models. Learning strategies for integrating STEM education are identified as project-based, problem-based and inquiry-based learning. Through this learning model the students carry out a project in collaborative ways in yielding a product.
Tujuan penelitian ini adalah untuk mengetahui pengaruh model PjBL menggunakan pendekatan STEM terhadap penguasaan konsep dan keterampilan berpikir kritis siswa. Penelitian dilakukan di minggu pertama dan kedua bulan April 2019. Penelitian ini menggunakan metode Pre Eksperimental. Populasi penelitian ini adalah Siswa kelas X MA Negeri 2 Ciamis. Pengambilan sampel menggunakan teknik purposive sampling. Instrumen yang digunakan adalah tes penguasaan konsep berupa pilihan ganda, tes keterampilan berpikir kritis berupa soal tes keterampilan berpikir kritis yang diadaptasi dari Piaw (2004). Data yang diperoleh dari kedua intrumen tersebut diolah secara statistik. Hasil penelitian 31% peningkatan penguasaan konsep yang menunjukkan kriteria sedang dan 75% peningkatan keterampilan berpikir kritis yang menunjukkan kriteria tinggi. Kata Kunci: PjBL, STEM, Penguasaan Konsep, Keterampilan Berpikir Kritis
