Critical thinking skills are important to practice early on in elementary school. It is believed that STEM based education could trigger the students to more critical. Individuals who have critical thinking skills will be able to communicate well. Many research results show that critical thinking skills can be stimulated by applying project-based learning in class. This research aims to describe critical thinking skills based on communication skills by using STEM-based Project-Based Learning. The research is a mixed-methods study. The population of this research consisted of fifth graders of Public Primary School 3 Pakis. The research instruments used were critical thinking skills tests, communication skills questionnaires and interview guidelines. The quantitative data was selected by purposive sampling technique. The qualitative data was based on the communication skills levels: high, moderate, and low. Based on the triangulation data it shows that students with high critical thinking skills reached the aspect of analyzing arguments; the moderate level could achieved simple aspects of explanation; while the lower level critical thinker only reaches the aspect of focusing questions. The STEM approach applied in project-based learning is able to encourage students to be able to communicate verbally and improve their critical thinking skills in solving problems.
This study aims to facilitate high school students’ communication skills and critical thinking ability with ICT-oriented problem-based online learning and assessment instrument with HOTS criteria. This research approach is pre-experimental, with the one group pre-test- post-test design. This study involved 36 students of XI MIPA 4 and biology teacher at a high school in Jepara, Indonesia. The number of samples determined using the purposive sampling technique. The data collected includes data on students’ critical thinking skills, students’ communication skills, implementation of the learning process, teacher and student response data regarding teaching materials, and the learning process. Data of critical thinking skills were analyzed using the n-gain test. Other data were analyzed descriptively qualitatively. The results showed that students achieved a critical thinking skill level with N-Gain 0.31 (medium category) and communication skills 83.00 (very good category). The average score of the implementation of the learning process is in a good category, meaning that all syntax is carried out well. Teachers and students consider that ICT-based teaching materials are quite practical to use. According to them, the learning process is in a good category (positive). Conclusion: students’ critical thinking skills and communication skills can be facilitated through online learning with ICT-oriented PBL approach teaching materials and ICT-oriented HOTS assessment instruments.
Tujuan penelitian ini adalah untuk menganalisis profil kompetensi sains siswa dalam pembelajaran literasi sains berpendekatan inkuiri saintifik. Penelitian ini merupakan penelitian experiment pretest-posttest control group design dengan sampel sebanyak 86 orang dari 2 kelas masing-masing di SMPN 1 Lilirilau dan MTs DDI Pattojo Kabupaten Soppeng Provinsi Sulawesi selatan. Hasil analisis penelitian menunjukkan bahwa kompentensi sains berdasarkan aspek PISA yaitu aspek penjelasan fenomena ilmiah mendapatkan rata-rata persentase tertinggi sebesar 81% dibandingkan kedua aspek lainnya yaitu identifikasi isu sains dengan rata-rata persentase sebesar 76% dan penggunaan fakta-fakta sains sebesar 71%. Sedangkan hasil analisis kompetensi sains berdasarkan aspek literasi sains, di antara keempat aspek, aspek batang tubung pengetahuan memperoleh rata-rata persentase tertinggi sebesar 80% dibandingkan ketiga aspek lainnya yaitu aspek cara menyelidiki sebesar 79%, cara berpikir sebesar 76%, dan interaksi antara SETS sebesar 78%.
