“Teachers are the main key to success in producing a quality and quality Indonesian gold generation in 2045. Therefore, teachers must have the ability to design learning to be meaningful and useful” (Pujiasih, 2020). As a Mathematics Teacher, you must always guide students regarding how to really learn (learning how to learn) and how to solve every problem in front of them (learning how to solve problems) that will be utilized and used in the future. Independent learning curriculum is a new step that makes some changes in terms of learning. During the COVID-19 pandemic, which has so far returned with the Omicron variant, all teachers/educators are required to turn their brains around to provide optimal online/virtual learning, as well as students who have to adapt to online/virtual learning and have to be extra in understanding the material. . The success of teachers and students in optimally practicing online learning in an independent learning curriculum will also have an impact on the development of students' thinking power. In online learning practices, with an independent learning curriculum, Mathematics educators/teachers have an important role, namely not only providing material but character education is also very important and useful for student behavior, by means of teachers not only providing material for free but can provide examples to students, so that students are able to be dedicated and innovate in the independent learning curriculum.

Artikel ini membahas tentang meningkatkan kualitas guru melalui program guru penggerak. Metode penelitian yang digunakan dalam penelitian ini adalah menggunakan pendekatan deskriptif kualitatif, melalui kajian telaah pustaka, penggunaan buku dan jurnal yang berkaitan dengan artikel ini, sehingga melalui artikel ini diharapkan dapat menumbuhkan minat guru untuk mengikuti program guru penggerak. Di era Industri 4.0, guru harus mampu berkembang dengan mengembangkan keterampilan pendidikan sehingga dapat mengajar dan mengajar siswa untuk memanfaatkan keterampilan berpikir mereka dengan lebih baik. Empat Standar kompetensi guru penggerak adalah; (1) Kompetensi pedagogik; (2) Kompetensi kepribadian; (3) Kompetensi profesional; (4) Kompetensi sosial. Guru Penggerak adalah pemimpin pembelajaran yang mampu menerapkan kemerdekaan dalam belajar dan ikut serta menggerakkan ekosistem dunia pendidikan untuk mewujudkan pendidikan yang berpusat pada peserta didikMelalui program guru penggerak, dibekali berbagai pelatihan dan lokarya yang tentunya akan dapat meningkatkan kualitas guru di Indonesia. Dengan demikian guru dapat menerapkan merdeka belajar yang dapat menciptakan pembejaran yang perpusat pada peserta didik, sehingga dapat menghasilkan siswa yang tidak hanya lulusan yang cerdas-cerdas secara akademik tetapi juga akan memiliki karakter yang luhur sesuai dengan nilai-nilai Pancasila.

Studi literatur ini mengkaji arah dan trend penelitian pendidikan matematika sejalan dengan trend dan temuan baru dalam pendidikan matematika. Topik penelitian pendidikan matematika masa lalu didominasi oleh NCTM dengan fokus ke siswa pendidikan dasar sebagai subjek penelitian. Saat ini topik penelitian pendidikan matematika mengkaji ke arah proses berpikir tingkat tinggi siswa dengan subjek yang merata. Penelitian pendidikan matematika ke depan juga akan mengkaji kemampuan berpikir tingkat tinggi yang lebih ditekankan pada kemampuan 4C (creativity, crictical thinking, communication, collaboration). Adanya pandemi covid-19 dan juga penerapan kurikulum kampus merdeka dan merdeka belajar akan berdampak terhadap pendidikan matematika.

This article is about research on the study of improving students’ problem-solving abilities in the learning process using the Problem Based Learning learning model with the Metacognitive approach. This article also contains a study of the interaction between the learning model and the students’ mathematical prior knowledge towards problem-solving abilities, and the study of student behavior in improving mathematical problem-solving skills. The research uses quantitative research methods with research subjects students in the experimental class and the control class. The research instrument consisted of tests of mathematical problem-solving abilities, observation sheets, and interview guidelines. Research findings include (1) the learning model used does not have a significant difference in mathematical problem-solving skills, both overall and based on prior mathematical knowledge, (2) the learning model used does not have a significant effect on improving mathematical problem-solving abilities, both overall and based on mathematical prior experience, and (3) there is no interaction between learning models and mathematical prior knowledge to improve mathematical problem solving abilities.

This study aims to determine the increase in students' creative thinking on the Social Arithmetic Material at  SMP Yapim Medan. This type of research is classroom action research with 26 research subjects. The instruments used were tests and observations. The average value of teacher observation in cycle I was 75% and increased in cycle II to 84.38% in the good category, while the average value of student activity observation in the first cycle was 62.25% in the good category, where as in cycle II it was 68.63% in the good category. The average of creative thinking of students in the initial test obtained 44.32% increased to 69.92% in the first cycle and 78.04% in the second cycle. Because the activities of students increased, teacher observation increased and the ability of creative thinking of students also increased from cycle I to cycle II, it can be concluded that the students' creative thinking ability with humanistic contextual learningincreases.
