The learning process of Mathematic in a conventional way took place in classroom was dominated by a teacher and gave less opportunity for the students to be more active in the learning process. Problem Based Learning by using Authentic Assessment is one of the alternatives to improve students’ activity in solving problems. This is a classroom action research. This research is focused on the improvement of students in problem solving; and improve the students’ activity. The instrument in this research consists of test in solving problem in Equation and Quadratic Function. Data Processing is done to find out the improvement of problem solving ability, students’ activity and teachers’ ability in managing teaching learning process. The result of the research shows: (1) The application of problem based learning by using authentic assessment improves the problem solving ability of mathematics. On 1st cycle, it is found 62.5% from the students has the ability of problem solving in the average of moderate. On 2nd cycle 85% of the students gets the average of moderate. (2) It is concluded that the students’ problem solving ability and the level of students’ activity are improve.

Kesehatan mental merupakan elemen penting dalam mendukung kehidupan sehat dan sejahtera, terutama di kalangan generasi Z yang menghadapi berbagai tantangan sosial, ekonomi, dan teknologi. Generasi Z, yang lahir antara tahun 1995 hingga 2010, dikenal sebagai generasi yang dekat dengan teknologi digital namun juga rentan terhadap gangguan kesehatan mental seperti depresi, kecemasan, dan stres. Penelitian ini bertujuan untuk menganalisis peran kesehatan mental dalam meningkatkan produktivitas generasi Z. Pendekatan ini menggabungkan analisis literatur dan data empiris untuk memahami dampak kesehatan mental terhadap kemampuan generasi Z dalam menjalani kehidupan produktif dan sejahtera. Hasil analisis menunjukkan bahwa kesehatan mental yang baik berkontribusi pada peningkatan kemampuan individu untuk mengelola tekanan, mengambil keputusan yang bijak, dan beradaptasi dengan perubahan. Sebaliknya, gangguan kesehatan mental dapat menurunkan produktivitas, meningkatkan risiko drop-out akademik, serta memengaruhi hubungan sosial. Faktor seperti stigma terhadap gangguan mental, kurangnya akses layanan kesehatan jiwa, dan eksposur terhadap tekanan digital menjadi hambatan utama. Oleh karena itu, upaya kolaboratif antara pemerintah, institusi pendidikan, keluarga, dan komunitas diperlukan untuk menyediakan dukungan promotif, preventif, kuratif, dan rehabilitatif. Dengan pendekatan yang holistik, generasi Z dapat menjadi individu yang lebih sehat secara mental, produktif, dan berkontribusi pada pembangunan bangsa.

This study aims to analyze the implementation of the Reciprocal Learning model based on Hypnoteaching in improving students’ self-confidence in mathematics learning. The background of this research is the low level of students’ self-confidence in mathematics classes, which affects their active participation, mathematical communication skills, and learning outcomes. The Reciprocal Learning model emphasizes activities such as summarizing, questioning, clarifying, and predicting, while the Hypnoteaching approach optimizes positive suggestion, persuasive language, and the creation of a comfortable and conducive learning environment. This study employed a quantitative approach with a quasi-experimental design. The research subjects were secondary school students divided into experimental and control groups. The research instruments included a self-confidence questionnaire, observation sheets of student activities, and mathematics achievement tests. Data were analyzed using descriptive and inferential statistical tests to determine differences in self-confidence improvement between the two groups. The results indicate that the implementation of the Hypnoteaching-based Reciprocal Learning model significantly improves students’ self-confidence compared to conventional learning methods. The improvement is evident in students’ courage to express opinions, ability to ask questions, participation in discussions, and confidence in solving mathematical problems. Therefore, this model is effective as an innovative instructional strategy to enhance both affective and cognitive aspects of students in mathematics learning.

This classroom action research aims to improve students’ critical thinking skills through the implementation of the STEAM-based Problem Based Learning (PBL) model at SMA Negeri 15 Medan. The research subjects were 32 eleventh-grade students. The study was conducted in two cycles, each consisting of planning, action, observation, and reflection stages. The research instruments included observation sheets, critical thinking skill tests, and documentation. The results show that the implementation of STEAM-based PBL significantly improved students’ critical thinking skills. In the pre-action stage, the percentage of students achieving mastery in critical thinking was only 37.5%. After the first cycle, it increased to 65.6%, and by the second cycle, it further increased to 87.5%. This improvement was supported by more active and collaborative learning activities, as well as students’ better ability to analyze problems systematically through the STEAM approach. Therefore, the STEAM-based PBL model is effective in enhancing students' critical thinking skills in the learning process at SMA Negeri 15 Medan.
