Dynamic human development in the 21st Century demands students to make innovations in the world of education. Students are required to have 21st-century skills, namely creativity, critical thinking, collaboration, and communication. In contrast, teachers are required to have skills that must be mastered. The six capabilities are mastery of knowledge/content, mastery of 21st-century pedagogy, the ability of expertise in the development and achievement of students and give support, mastery of learning psychology skills; having counseling skills; and competence in using information technology and media. This article aims to discuss issues related to how to improve the ability of teachers and students to master 21st-century skills? Also, what extent is the role of digital literacy and STEM integration in improving 21st-century skills? This article using literature literacy methods sourced from international and national journals, books, and other relevant sources. Based on the study, it concluded that digital competence is not an absolute determinant of the development of 21st-century skills in students. Digital ability is a supporting factor for mastering 21st-century skills that should have been introduced and taught through schools. STEM learning with multidisciplinary mastery of science needs to be optimized in schools in Indonesia so that the expected learning objectives are in line with the demands of the 21st-century.

Abstrak: Perkembangan dunia teknologi dan informasi yang semakin pesat dapat memberikan alternatif bagi pendidik untuk menggunakan berbagai media pembelajaran salah satunya yaitu Physics Education and Technology (PhET). Tujuan penulisan artikel ini untuk menjelaskan tentang 1). Efektivitas penerapan media simulasi PhET dalam proses pembelajaran fisika, 2) Strategi penerapan media simulasi PhET dalam proses pembelajaran fisika, serta 3) Kelebihan dan kekurangan media simulasi PhET dalam proses pembelajaran fisika. Penulisan artikel ini menggunakan metode kualitatif berdasarkan filosofi post positivisme dengan teknik pengumpulan data berupa tri-anggulasi (gabungan), yaitu penelitian kepustakaan melalui pengumpulan data, terutama data verbal seperti buku, artikel, catatan, dan berbagai literatur ilmiah lainnya. Data yang dikumpulkan kemudian dianalisis secara induktif. Berdasarkan hasil tinjauan pustaka, analisis data, dan diskusi dapat disimpulkan bahwa 1). Media simulasi PhET secara efektif digunakan untuk membantu guru dan siswa dalam mempelajari konsep fisika, 2) media simulasi PhET sangat baik dikombinasikan dengan model pembelajaran inkuiri, dan 3) media simulasi PhET memiliki keuntungan yaitu efektif dalam menjelaskan konsep fisika yang sifatnya abstrak, sedangkan kekurangannya adalah bahwa implementasi di sekolah sangat tergantung pada unit komputer yang tersedia.Kata kunci: Simulasi Interaktif PhET, Inkuiri Terbimbing, Pembelajaran FisikaAbstract: The rapid development of technology and information world can provide an alternative for educators to use various learning media, one of which is Physics Education and Technology (PhET). The purpose of this review is to explain 1). The effectiveness of the application of PhET simulation media in the physics learning process, 2) The strategy of applying the PhET simulation media in the physics learning process, and 3) The anvantages and disanvantages of the PhET simulation media in the physics learning process. The writing of this article uses a qualitative method based on a post positivisme philosophy with data collection techniques in the form of tri-anggulation (combined), namely library research through data collection, especially verbal data such as books, articles, notes, and various other scientific literature. The data collected is then analyzed inductively. Based on the results of literature review, data analysis, and discussion it can be concluded that 1). PhET simulation media are effectively used to help teachers and students in learning physics concepts, 2) PhET simulation media are very well combined with inquiry learning models, and 3) PhET simulation media has the advantages of being effective in explaining abstract physical concepts, while the disadvantages is that the implementation in schools is very dependent on the computer units available.Keywords: PhET Interactive Simulations, Guided Inquiry, Physics Learning

This study investigates the implemented distance learning system from home as the Indonesian government's policy slogans during the COVID-19 pandemic. The use of various distance learning system platforms currently available adjusted to the learning process's needs to carry out provides a solution to break the chain of spreading COVID-19 in Indonesia. The research using a literature review that consists of four stages, namely (1) Identification of research topic keywords, (2) identification of abstracts from various literature sources, (3) making notes of identification results, and (4) link notes periodically. Based on the results and discussion, distance learning is an effective solution to continuing the learning process during the COVID-19 pandemic, when it does not allow direct learning in the classroom. However, to increase distance learning success, various considerations are needed, such as infrastructure, teacher and student readiness, and expected learning outcomes. Therefore, teachers as an essential factor in the achievement of the learning process, especially during the COVID-19 pandemic, must be able to create and provide usefully and not dull learning conditions, one of which is by trying to use various learning models platforms such as Zoom Cloud Meeting, Google Forms, Jitsi Meet App, Whatsapp Groups and more.

Learning during a pandemic requires every teacher to be able to improve literacy skills in terms of using technology to help the learning process. However, due to the rapid paradigm shift due to the COVID-19 pandemic, from direct learning to online-based learning. Therefore this activity was carried out to improve the ability of Madrasah Aliyah Plus Nurul Islam Sekarbela teachers in using various learning support applications, especially the Ministry of Religion E-learning. The Ministry of Religion E-learning application is an application recommended by the Ministry of Religion of the Republic of Indonesia for use in the distance learning process during the COVID-19 pandemic at the madrasa level. The use of applications in the learning process is expected to be able to increase student motivation and enthusiasm for learning during the learning period from home and still pay attention to health protocols. Participants in this activity were attended by all teachers who teach at Madrasah Aliyah Plus Nurul Islam with a total of 36 people. In its implementation, this activity consists of three stages, namely 1. The preparation stage, 2. Implementation stage, and 3. Evaluation stage with each activity an evaluation process is carried out to ensure that the initial objectives of this activity can be achieved. Based on the activities that have been carried out, it can be concluded that this mentoring activity is needed by teachers in understanding the use of the Ministry of Religion E-learning application with various supporting features and its implementation. Also, after carrying out this activity, teachers began to get used to the use of the Ministry of Religion's E-learning application in carrying out the learning process during the COVID-19 pandemic.

This study aims to determine level of critical thinking ability when learning process kinetic theory of gas with conceptual change model outcome review from high school student learning style. This type of research is pre experiment with factorial design  (level 3). The research population is all grade XI IPA in SMA Negeri 7 Mataram with sampling technique using purposive sampling. Three samples were taken as experimental class which is class XI MIPA 1 taught with CCM visual style, XI IPA 2 taught by CCM auditory style, and XI IPA 3 taught with CCM kinesthetic style. The student learning style data on was taken using by questionnaire with 4 alternative options. The critical thinking ability’s data collected by using sheets of critical thinking skill based on student's answer to LKS. The result data was analyzed with descriptive statistical test and classified based on categorization level of critical thinking ability. Based on the analysis result, it can be concluded level of critical thinking ability when learning process kinetic theory of gas with conceptual change model outcome review from high school student learning style including into medium category with value of 70,87.
