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

Standards Documents

The NCTM's standards documents (1989, 1991) encourage teachers to present students with activities that are drawn from real-world contexts and that help them make connections among various content areas. The following situation involves a wealth of mathematics for middle school and high school students, including measurement, data analysis, ratio, predictions, and graphing.

Computational Difficulty

Although solving polynomial equations is important in mathematics, most high school students can solve only linear and quadratic equations. This is because the methods for solving cubic and quartic equations are difficult, and no general methods of solution are available for equations of degree higher than four. However, numerical methods can be used to approximate the real solutions of polynomial equations of any degree. Because they involve a great deal of computation they have not traditionally been taught in the schools. Now that most students have access to calculators and computers, this computational difficulty is easily overcome.

<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>

AbstractGlobal warming and climate change are serious issues facing humanity at present and education needs to focus on including informed-decision in classroom practices. The conceptual framework used in this study has provided interconnections that influence beliefs and understandings in providing a knowledge base for making “informed-decision” among high school students. This study was conducted in three year 9 classes in two high schools in the UK and among 65 students. An inquiry intervention model was developed using the 5E instructional model (Engage, Explore, Explain, Elaborate, and Evaluate) to identify beliefs and understanding and to strengthen students’ knowledge base. This study used a design-based research setting and utilised a mixed methodology. The Wilcoxon signed-rank tests were computed to examine the pre-post-difference among questionnaire items, and structural equation modelling (SEM) was utilised to explore the relationship between belief, understanding, and intention. Data analysis of the intervention revealed that students developed a strong understanding of the causes and effects of global warming. There is evidence that students used that knowledge to “inform-decision” in relation to global warming and climate change. Promoting informed decision-making through science teaching can encourage responsible action in the future. The real gap identified in this study is that the regular school curriculum does not engage socio-scientific issues in the real world and has no opportunity to organise an inquiry-based instructional sequence for informed decision-making.

Time To Learn

Researchers, parents, and educators consistently observe a stark mismatch between biologically preferred and socially imposed sleep-wake hours in adolescents, fueling debate about high school start times. We contribute neural evidence to this debate with electroencephalogram (EEG) data collected from high school students during their regular morning, mid-morning and afternoon classes. Students’ baseline alpha brain activity decreased as the day progressed, consistent with adolescents being least attentive early in the morning. While students showed consistently worse performance and higher alpha power in the early morning classes, quiz scores and alpha levels in the afternoon varied by individual focus and class activity. Together, our findings demonstrate that class time is reflected in adolescents’ brain responsiveness in a real-world setting, and corroborate educational research suggesting that mid-morning may be the best time to learn.
