Ilmu pengetahuan dan teknologi yang semakin berkembang pesat menuntut manusia untuk tidak hanya memiliki kemampuan kognitif namun juga memiliki keterampilan lain yang dituntut di abad 21. Terdapat 4 keterampilan yang dituntut dimiliki oleh manusia di abad 21 ini, salah satu diantaranya adalah keterampilan berkomunikasi. Penelitian ini bertujuan untuk menganalisis profil keterampilan komunikasi siswa SMP pada pembelajaran IPA berbasis STEM (Science, Technology, Engineering, and Mathematics). Penelitian ini melibatkan sampel sebanyak 16 orang siswa kelas VIII yang mengikuti ekstrakurikuler STEM di salah satu SMP negeri di Kota Bandung. Keterampilan komunikasi siswa ini dibagi ke dalam komunikasi lisan dan komunikasi secara tertulis. Pengumpulan data dilakukan melalui proses presentasi dan pembuatan laporan yang dinilai berdasarkan rubrik yang telah ditentukan. Hasil analisis data menunjukkan bahwa pada keterampilan komunikasi lisan terdapat 43,75% siswa berada pada kategori 'Sesuai Standar' dan 56,25% siswa berada pada kategori 'Tidak Memenuhi Standar.' Sementara itu, pada keterampilan komunikasi secara tertulis ditemukan bahwa: (1) Terdapat 56,25% siswa berada pada kategori Intermediate, (2) Terdapat 31,25% siswa berada pada kategori Emerging, (3) Terdapat 12,50% siswa berada pada kategori Basic, dan (4) Tidak tedapat siswa yang berada pada kategori Advance. Berdasarkan data tersebut, dapat diketahui bahwa mayoritas siswa masih berada pada kategori Intermediate untuk komunikasi tertulis dan 'Tidak Memenuhi Standar' untuk keterampilan komunikasi lisan. Hal tersebut menunjukkan bahwa keterampilan komunikasi lisan siswa dalam pembelajaran IPA berbasis STEM masih perlu dioptimalkan.
Creative Problem Solving (CPS) is a process to solve a problem faced imaginatively and resulted in effective action. There are 4 aspects that are assessed in CPS which are fact finding, problem finding, idea finding, and solution finding. With the assumption that CPS could be trained and improved, this research aim is to investigate the enhancement of senior high school student's CPS skills after practicing STEM-based learning. The topic in this research is the concept of momentum and impulse using LEGO® Mindstorm EV3 as the media. This study uses a pre-experimental method with one group pretest-posttest design. The sample of this research is 25 senior high school students in Bandung that are determined with the cluster random sampling technique. By analyzing the N-Gain, the result shows that the enhancement of CPS skill is in the middle category with
Fluid pressure is considered as an abstract concept so that an innovative method must be used to help the students understand it correctly. We introduced Above Ground Storage Tank (AST) to the students to help them grasp the fundamentals of fluid pressure and evaluated how this approach improved their scientific communication ability. Based on their ability in communicating the mechanism of fluid pressure, students were able to organize their knowledge, delivering their knowledge to other people, and making a better conclusion after the introduction of AST. Thus, it can be concluded that the introduction of AST can improve students’ scientific communication ability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
