Numeracy and literacy are the focus of Indonesia's education system. This is evident from the implementation of the Minimum Competency Assessment (AKM), which has been part of the national annual assessment since 2021. The results are analyzed and reflected upon to assess the quality of education in implementing schools. Students' numeracy skills can improve if they use reasoning to solve problems. Reasoning connects the concepts they hold with the context of the problem at hand. Reasoning results are used to interpret, analyze, and make decisions. The reasoning in question focuses on adaptive reasoning (reflection, explanation, and justification). Research was conducted to describe the adaptive reasoning of high school students through the answers of students who participated in a reasoning competition. The instrument used is a numeracy test. This research is qualitative with descriptive methods. Analysis was conducted on the three student answers that obtained the highest scores (purposive sampling) and focused on the fertilizer theme. This theme is presented in graphic form as a stimulus with two questions that students need to answer. The data analysis technique in this research involved reducing the data. The result obtained was that one student used aspects of adaptive reasoning (reflection, explanation, and justification) completely in answering questions. This indicates that this student can solve problems using adaptive reasoning. This student is said to have good numeracy skills because they can use adaptive reasoning.BAHASA INDONESIA ABSTRACT: Literasi dan numerasi menjadi salah satu fokus pada dunia pendidikan di Indonesia. Hal ini terlihat dari pelaksanaan Asesmen Kompetensi Minimum (AKM) yang menjadi bagian dari asesmen nasional dilakukan secara berkala sejak tahun 2021. Hasilnya dianalisis dan direfleksikan menjadi mutu pendidikan dari sekolah yang melaksanakan. Kemampuan numerasi siswa dapat dikatakan baik jika siswa dapat menggunakan nalarnya untuk menyelesaikan permasalahan. Penalarannya digunakan untuk mengaitkan antara konsep yang dimiliki dengan konteks masalah yang dihadapi. Hasil penalaran dimanfaatkan untuk menginterpresi, menganalisis, sampai mengambil keputusan. Penalaran yang dimaksud berfokus pada penalaran adaptif (reflecting, explaining, dan justifying). Penelitian dilakukan untuk mendeskripsikan penalaran adaptif siswa SMA melalui jawaban siswa yang mengikuti lomba nalaria. Intrumen yang digunakan adalah tes numerasi. Jenis penelitian pada penelitian ini adalah kualitatif dengan metode deskriptif.

The lack of activities to strengthen engineering literacy implemented at the elementary school level and the dominant learning carried out using text books are the main factors in the low engineering literacy of elementary school students. This community service activity aims to strengthen the engineering literacy of elementary school students through the Hydraulic Robotic Arm (HydRA) assembly activity at SDN 21 Sungailiiat. Through this activity, it is hoped that it can increase students' knowledge and skills related to engineering literacy, which can be used and developed further to welcome the era of society 5.0. This community service activity is carried out through a series of activities, starting with an initial survey carried out at partner locations, followed by preparing activity plans and creating activity materials, up to the activity implementation stage. This activity took place for one day at SD Negeri 21 Sungailiat and was attended by 26 students of class V A. The activity of strengthening elementary school students' engineering literacy through the Hydraulic Robotic Arm (HydRA) assembly activity at SDN 21 Sungailiiat went well, as seen by the increase in knowledge and skills students related to engineering literacy.

The fact that gadgets are no longer luxury items and every student certainly has them presents an opportunity for teachers to create meaningful learning. One way to do this is by conducting learning assisted by PhET Simulations. These simulations offer various concepts in mathematics, physics, biology, and chemistry to be taught in the form of simulations. The use of these simulations allows the role of the teacher as a learning facilitator to be effectively carried out theoretically. However, the use of simulations has not been carried out to assist teachers in teaching material. Strengthening needs to be done. The strengthening is carried out at SMP N 1 Pemali through providing focused reinforcement for Mathematics and Natural Sciences (IPA) teachers. The reinforcement implementation is equivalent to a 6-hour training with activities starting and ending with tests to see if there is any improvement in understanding related to the reinforcement provided. Information was obtained indicating a good improvement in understanding related to the use of PhET as a learning medium for teachers is 37,5 %. In addition, the reinforcement provided received a positive response. Reinforcement practice in using PhET simulations has a good impact on MIPA SMP’s teachers as facilitators in learning.

Understanding is a basic middle level thinking skill based on the revised Bloom's taxonomy. One learning model that is student-centered is Interactive Lecture Demonstration (ILDs). Surveys prove that particle dynamics is one of the physics topics that is difficult for students to understand. As a result, students cannot construct their own understanding. The development of ILDs model-oriented digital teaching materials is a solution. The subjects focused on students in class XI Science in two classes which were used as experiment and control. Development research applies four stages, including definition, design, development and dissemination. The aim of this development is to improve the ability to understand. So for dissemination, mixed research methods are applied with a sequential explanatory strategy. This strategy was chosen because research is dominated by quantitative research. Subjects were given two instruments, namely a comprehension ability test to obtain an overview of comprehension abilities that can be strengthened through the implementation of digital teaching materials and an attitude scale sheet to see students' perspectives regarding the implementation of digital teaching materials. The results obtained by the characteristics of teaching materials contain a series of stages of the ILDs model and can improve understanding abilities.
