Abstract The development of Worksheets based on the STEM approach pays attention to the elements of writing, the hierarchy of materials, and the selection of questions as an efficient and effective stimulus. This research aims to produce Worksheets based on the STEM approach that meets the feasibility of improving students’ critical thinking skills. The development model in this research refers to the 4D (four-D) research and development model by taking sample data from high school science students in the former Besuki Residency, namely Jember, Situbondo, Banyuwangi, and Bondowoso Regencies. The research instrument uses tests, observations, and documentation. The research results show that Worksheets based on the STEM approach meet the valid, practical, and effective criteria for improving students’ critical thinking skills. This research implies that the availability of Worksheets is expected for students to research teaching materials independently. In Worksheet, students will get materials, summaries, and assignments related to the material.

The Subject

One of the teacher's efforts for students to play an active role in learning is to choose media that can practice the skills of conducting experiments, improve critical thinking skills so that students can develop the concept of science. This research is a development research with ADDIE development model. LKPD products are tested before being validated by media experts and material experts. The results of media validation obtained a percentage value of 98.75% with a very good category, and material validation obtained a percentage value of 90.00% with a very good category. The results of small group trials and large group trials were 93.05% and 86.25%, respectively, both included in the excellent category. Furthermore, for the perception of teachers obtained a percentage value of 97.72% with a very good category. Based on the results of the study it was concluded that the inquiry-based LKPD was guided on the subject of the classification of living thing  for Seventh grade of Yunior High School suitable for use in learning. Abstrak  Salah satu upaya guru agar peserta didik berperan aktif dalam pembelajaran adalah dengan memilih media yang dapat melatih keterampilan melakukan eksperimen, meningkatkan keterampilan berpikir kritis sehingga peserta didik dapat mengembangkan konsep IPA.  Salah satunya adalah dengan menggunakan media LKPD berbasis inkuiri terbimbing.  Penelitian ini bertujuan menghasilkan LKPD berbasis inkuiri terbimbing pada pokok bahasan klasifikasi mahluk hidup, juga untuk mengetahui persepsi peserta didik dan guru terhadap LKPD yang dikembangkan.  Penelitian ini merupakan penelitian pengembangan dengan model pengembangan ADDIE.  Produk LKPD sebelum diujicobakan terlebih dahulu divalidasi oleh ahli media dan ahli materi.  Hasil validasi media diperoleh nilai persentase 98,75% dengan katagori sangat baik,dan validasi materi diperoleh nilai persentase 90,00% dengan katagori sangat baik.  Hasil uji coba kelompok kecil dan uji coba kelompok besar secara berurutan adalah 93,05% dan 86,25%, keduanya termasuk dalam katagori sangat baik.  Selanjutnya untuk persepsi guru diperolah nilai persentase 97,72% dengan katagori sangat baik.  Berdasarkan hasil penelitian disimpulkan bahwa LKPD berbasis inkuiri terbimbing pada pokok bahasan klasifikasi mahluk hidup untuk kelas VII SMP layak digunakan dalam pembelajaran.

This study examined the application of Reading Strategy Instruction (RSI) in a reading class to promote the critical thinking skills of the second language learners. It aims to find out (1) the critical thinking elements in the questions formulated by the participants before the application of RSI, and (2) the critical thinking elements found in the (a) three selected questions, (b) answers, and (c) reflections written by the participants after the application of RSI. This study included sixteen grade 11 participants of a bilingual school in Jakarta, aged between 16 to 18 years old. The participants underwent two stages (1) before the application of RSI, and (2) after the application of RSI. The RSI applied in this study was a modification of Rothstein & Santana’s (2014) “Question Formulation Technique” and Alder’s (2001) comprehension strategies in answering questions. The collected data were analysed by using the modified critical thinking indicators proposed by Mason (1991) and Henri (1992). The results of the study revealed that applying RSI in the reading class was beneficial in promoting the participants’ critical thinking skills. RSI helped the participants to (i) think differently, (ii) use prior background knowledge, (iii) question the facts given in the text, (iv) identify the issues given in the text, (v) give valid solutions to the problem, (vi) connect themselves with the text and the world, and (vii) justify their arguments using valid examples.

In 21st century learning, critical thinking skills are the main choice that must be mastered by students. This study aims to determine the effectiveness of local wisdom-based science teaching materials in improving junior high school students’ critical thinking skills. Most science teachers still apply teacher-centered learning, so students tend to be passive. This type of research is quasi-experimental with a pretest-posttest control group design. The study was conducted in the even semester of the 2019/2020 school year. The subjects of the research were grade VII students. Data collection techniques and instruments in the form of tests that include indicators of critical thinking skills. Data analysis used homogeneity test, Kolmogorov Smirnov normality test, independent sample t-test, and n-gain score. The results of the independent sample t-test are sig. (2-tailed) = 0,000<sig. α = 0.05. Students’ critical thinking skills in the experimental class were higher (N-gain score = 39.09%) than in the control class (N-gain score = 12.03%). Based on the study results, it can be concluded that there is a significant influence on the application of local wisdom-based teaching materials in improving the critical thinking skills of middle school students in the moderate category.
