Secret ciphers fascinate students and are an ideal subject with which to motivate them to study mathematics. Recent articles in the Mathematics Teacher, for example, have described how various types of ciphers can be taught to high school students to enhance their learning of statistics (Feltman 1979), matrices (Camp 1985), functions and their inverses (Reagan 1986), and remainder arithmetic (Meneeley 1981). Ciphering also offers interesting examples of how so-called “pure” mathematics can be applied to real-world problems (Hilton 1984).

This study aims to see the strengths and weaknesses of the teacher in the teaching process based on the competence aspects of the mathematics teacher and to describe the situation and state of the teacher's competence when in the learning process in the classroom based on student perceptions associated with the competence of the students themselves. Data processing techniques using data analysis Structural Equation Modeling (SEM). The population of this study were junior high school students in Labuhanbatu. The sampling technique used was proportional random sampling leading to simple random sampling, the number of samples obtained was 219 students. Techniques in the data collection process were carried out by distributing a questionnaire on students' perceptions of the mathematics teacher's performance consisting of 48 questions in the form of a Likert scale.

Abstract The aim of this study was to ascertain high school students' proportional reasoning in the sense of the COVID-19 pandemic. How do students' thoughts flow when confronted with problems requiring proportional reasoning? This research is a mixed study by collecting data through problem-solving questions to 253 junior high school students in Muaro Jambi, Jambi Province, Indonesia. The problem-solving activities are based on real-world scenarios and require reasoning that is proportional and pertinent to the COVID-19 pandemic context. Due to the ongoing COVID-19 pandemic, the test is administered through the Whatsapp framework. Students' responses are examined in detail to ascertain their proportional reasoning skills. The results indicate that almost all students correctly answered the first question. However, only a small percentage of students were able to answer to and make the correct argument for the second question. The findings indicated that students demonstrated a reasonable level of proportional reasoning when confronted with the COVID-19 pandemic situation. According to the findings of this report, it is important for teachers of mathematics to establish learning activities and problem-solving tasks that help students improve their proportional reasoning skills. Keywords: COVID-19; Problem Solving; Proportional Reasoning; Real-World Situations AbstrakTujuan dari penelitian ini adalah untuk menggali penalaran proporsional siswa SMA  dengan konteks pandemi COVID-19. Bagaimana alur pemikiran siswa ketika dihadapkan pada masalah yang membutuhkan penalaran proporsional? Penelitian ini merupakan penelitian campuran dengan pengumpulan data melalui pertanyaan pemecahan masalah kepada 253 siswa SMP di Muaro Jambi, Provinsi Jambi, Indonesia. Kegiatan pemecahan masalah didasarkan pada skenario dunia nyata dan membutuhkan penalaran yang proporsional dan relevan dengan konteks pandemi COVID-19. Karena pandemi COVID-19 yang sedang berlangsung, tes dikirim melalui aplikasi Whatsapp. Tanggapan siswa diperiksa secara rinci untuk memastikan kemampuan penalaran proporsional mereka. Hasilnya menunjukkan bahwa hampir semua siswa menjawab pertanyaan pertama dengan benar. Namun, hanya sebagian kecil siswa yang mampu menjawab dan membuat argumen yang benar untuk pertanyaan kedua. Hasil penelitian menunjukkan bahwa siswa memiliki alur penalaran proporsional yang cukup baik dengan menggunakan konteks kondisi pandemi COVID-19. Menurut temuan  ini, penting bagi guru matematika untuk menetapkan kegiatan pembelajaran dan tugas pemecahan masalah yang membantu siswa meningkatkan keterampilan penalaran proporsional mereka. Kata kunci: COVID-19; Pemecahan Masalah; Penalaran Proporsional; Situasi Dunia

<p>Desire to apply knowledge gained in school is the characteristic of high school students. These characteristic actually has been accommodated into 2013 curriculum. However, low interest of high school students to study chemistry was still found. Various learning methods have been developed to improve learning interest in the classroom. The effort to increase students' interest in chemistry can also be done outside the classroom. In this paper will be presented a theoretical study of joyful learning real world chemistry through VAKSIN strategy during school break. The strategy will be given in two ways, through science camps or excursion. Materials to be provided during the science camp are making green chemistry paint, exploration of cat litters, and simulations of waste water purification. Excursion can go into two places, the industry or university. VAKSIN strategy will have positive impact on students, teachers, industries, and universities.</p><p><em> </em></p><p><strong>Keywords</strong>: high school students, joyful learning, real world chemistry, VAKSIN strategy</p>

The present Project developed at Escola Família Agrícola Dom Antonio Possamai - EFADAP, aims to report the experimental activities, with the Mathematics teacher together with high school students, thus building rockets using a PET bottle in the study of concepts from physics, mathematics and chemistry, aiming to bring students closer to experimental activities, showing at the same time, the combination of theory and practice, where they would have autonomy to elaborate and test their hypotheses about the chemical reaction used in the rocket. The experiment is proposed to students and the teacher is a mediator of the process of study and application of knowledge, organizing weekly classes, until the end of the project. In the final considerations, the steps that students used to develop the experiment during classes are presented as a result of the development of the activity.

This paper reports on the results of the design and implementation of a didactic device proposed by a mathematics teacher-trainee. This student did a course designed for didactic - mathematical training with the aim of adopting a non-traditional didactic model based on research, while linking mathematics with other disciplines. The teacher-trainee developed its implementation in a senior- course of an Argentine high school. This didactic device is based on the analysis of a real and present situation whose study allows to make some gestures of the questioning world paradigm, in the current conditions of an Argentine high school.
