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.

Illustrative Case

AbstractHydraulic fracturing (‘fracking’), like other complex social and environmental issues, is a controversy about science which raises educational questions about how best to prepare young people to understand, respond to and, where necessary, act (or not) in response. It raises political questions. We present a state-of-the-art review of research literature on fracking and education using systematic strategies, with a view to finding out how it is framed in educational situations and how politics enters the science classroom. This serves as an illustrative case of how contested scientific and technological interventions with implications for the environment and society are treated in school science. The review is supplemented by interviews with 10 teachers of science and engineering working in schools or colleges near sites of operational exploratory fracking. We find that the research literature on teaching hydraulic fracturing is sparse, with only 25 studies relating to teaching and learning about fracking. Few studies (n = 7) relate to high school education. Where it features in science education, fracking is used as a context for interdisciplinarity and critical thinking, and lends itself to approaches using discussion, dialogue and modelling. Outcomes from fracking education range include knowledge gains and critical thinking. Teachers interviewed tended not to see a place for fracking in the curriculum or in the classroom and were averse to including politics in upper high school science education. Our analysis suggests depoliticization through absence of this specific complex environmental issue from the public (education) sphere, reinforced by the desire for ‘balance’ in high school science education and instrumental approaches to science education which prioritize assessed learning outcomes. Dealing with complex social and environmental issues such as hydraulic fracturing in the years of compulsory science schooling is necessary because scientific knowledge is necessary but not sufficient to prepare young people for the critical scientific literacy required to meet sustainable development goals. There is a need to assess and respond to the educational needs of local communities affected by industrial interventions such as fracking. These findings are likely to be relatable to other issues where there are local and global consequences of action or inaction and where the environment and health are pitted against economic and energy demands.

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.
