The study aims to identify kinds of high school students’ misrepresent in doing their tasks and to provide the appropriate scaffolding as a solution to help the students. This is a qualitative descriptive research. The research subject consists of three junior high school students who have different abilities in Mathematics. They were selected out of 92 students. This research studied the conceptual errors, procedural mistakes, and students’ technical mistakes in working on the problems based on the stages of Kastolan mistakes and the scaffoldings given. Furthermore, the data were collected by using the way of testing, interviewing and documenting techniques. The research data were guarantee validated with the triangulation method. The result of the research showed that there were some errors done by the students in doing the tasks. They were the conceptual errors, procedural mistakes, and technical errors. The scaffoldings given to help the students do the tasks for Level 1 (environmental provisions), Level 2 (explaining, reviewing dan restructuring), and Level 3 (developing conceptual thinking).

Penelitian ini bertujuan untuk menganalisis kemampuan penalaran proporsional siswa SMA dalam memecahkan masalah matematika. Subjek pada penelitian deskriptif kualitatif ini adalah 3 siswa kelas X SMA Negeri 2 Salatiga berkemampuan matematika tinggi. Instrumen utama adalah peneliti sendiri, didukung oleh instrumen tes dan pedoman wawancara. Data hasil tes dan wawancara dianalisis menggunakan langkah reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa ketiga subjek memiliki kemampuan penalaran proporsional yang berbeda dalam memecahkan masalah matematika. Kemampuan penalaran proporsional subjek S cenderung berada pada level 1 dengan menunjukkan strategi menggunakan gambar dan membuat perbandingan kualitatif. Kemampuan penalaran proporsional subjek F cenderung berada pada level 2 dengan menunjukkan strategi menghubungkan model melalui perhitungan numerik, menggunakan unit komposit, dan menggunakan penalaran kuantitatif. Kemampuan penalaran proporsional subjek M cenderung berada pada level 3 dengan menunjukkan strategi menggunakan cara formal dan mengetahui hubungan invarian dan kovarian. Ketiga subjek menunjukkan kemampuan penalaran proporsional pada level 0 dalam memecahkan masalah yang memerlukan perbandingan aditif dan multiplikatif dengan hanya menggambarkan situasi perubahan dalam pandangan aditif.

This study aimed to test the SOS game used as a means to warm up. SOS games were usually played on paper. The trial game consists of 3 different levels. This game could be used as a movement activity to warm up. With some modifications, this game was tested. The trial was conducted on junior high school students, totaling 40 students. The data was obtained by measuring the pulse. Pulse was measured by counting the pulse in the neck for 10 seconds. The calculation result is multiplied by 6 to determine the number of pulses per minute—data analysis by comparing the measurement results with heating criteria based on age. The results showed that the first trial had a pulse rate of 142. Based on trial with 40 samples each at level 1, 140 level 2, 143, and level 3, 143 beats per minute. All of these pulses were in the exercise pulse. So it can be recommended that this game be used for heating purposes.

Justification is the process of justifying a claim that is supported with evidence. Justification is the center of mathematics. Justification plays an important role in learning because it can help students improve understanding of mathematical concepts. By using a qualitative approach, this study aims to analyze the mathematical justification of high school students in solving problems on statistical topics. This research was conducted on 122 high school students by giving justification test questions on the topic of statistics resulted in 17% (21 students) included in the level justification level 3, 16% (19 students) included in level 2, 47% (47 students) included in level 1, and 20% (25 students) the rest are included in level 0. Further analysis was carried out to see the mathematical justification process by each level. The mathematical justification process consists of three stages, 1) the process of recognition; 2) the development process (building-with), and 3) understanding (awareness) process. Level 3 and level 2 students can recognize the problem and determine the right strategy to solve the problem, level 3 and level 2 students are also able to execute the strategy and interpret the results of the calculations they have done. The difference in level 3 and level 2 students lies in the understanding the concepts they have. Level 1 students can recognize problems and determine solution strategies. Although level 1 students can recognize and do calculations well, level 1 students fail in interpreting the results of calculations performed. While students who are level 0 are not able to recognize the problem, so level 0 students do not carry out the justification process.

<div class="WordSection1"><p>Argumentation is scientific discourse in science learning that is used as a link between knowledge from an environment and concepts in science learning. Through argumentation skills can be controlled student understanding in connecting facts with concepts in learning. This study aims to analyze students' argumentation ability on buffer solution subject. Students' argumentation ability is divided into 4 levels; level 1 (claims), level 2 (claims with data), level 3 (claims with data and one rebuttal), and level 4 (claims with more than one rebuttal). Data analysis was done by a qualitative descriptive method using a case study method. The case study method was chosen so that a study of 92 students who were research participants could be carried out in depth and comprehensive. The results obtained that the students' argumentation ability was at level 1 and level 2 argumentation. This shows that students' argumentation skills are still at low and medium levels. The results of this study can be used as a basis for improving the quality of teaching and further research.</p><strong><em></em></strong><em></em><em></em></div><em><br clear="all" /> </em>

The Student’s argument can be raised and developed using socioscientific issues. Socio-scientific issues about health is one of the social problems that the subject of public debate. This study aims to describe the complexity of the arguments in elementary school, middle school, and high school. The three level of education is a school which is shaded by one of the Foundation in Bandung. Participants involved in the study consisted of 31 elementary students, 14 middle school students, and 23 high school students. Data taken using a quisioner consist of five items concerning socioscientific issues as well as individual interviews based on the answers to the test written description. Data identified using Toulmin Argumentation Adaptation Pattern (TAP), which consists of four levels, namely, level 1 (claim), level 2 (claims, data and / or warrants), level 3 (claims, data / warrant, backing), and level 4 (claims, data / warrant, backing, qualifier). The results showed that the development of increasingly rising complexity of arguments according to their level. The complexity of the arguments on elementary students reached level 2-3, middle school and high school reached level 3. Percentage of level 3 more ascending towards the middle school to high school. Meanwhile, if viewed from the dominates of the arguments category level, level 2 emerged as the dominant category in elementary school, middle school, and high school.

In Indonesia, exploring what the students know about the characteristics of Covid-19 symptoms is crucial during Covid-19 pandemic. It is because to picture self-awareness of students about Covid-19 and readiness the students to face offline learning in school. The reason led a purpose of the research, that was, to describe the students’ contagion literacy about the characteristics of Covid-19 symptoms. The participant of the descriptive research was junior high school students in East Java, Indonesia. The data collected through online test consisted of 3 questions. The findings stated that (1) 34% of the students were able to answer Question 1; (2) 27% of the students answered correctly; and (3) 49% of the students chose correct answer. The implication of the research was that the student’s contagion literacy needs to be improved and the educators have to concern to the level of contagion literacy for junior high school students.
