<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>

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.

Choosing a major that will be taken up in college can raise doubts and even anxiety for the final year high school students. Various factors trigger this doubt and anxiety, especially for choosing across majors. Crossing-major is the decision to choose a field of science to be pursued in higher education, which is different from the field of study at the high school level. This study was intended to describe the psychological dynamics of students who decided to cross majors. This study used a case study-based qualitative descriptive model. The case study was chosen so that this study obtained more detailed and in-depth data from the participants. The data collection techniques used observation and interviews. The results of the analysis indicate the existence of emotional aspects related to anxiety and doubt experienced by students when choosing a further education major, which is caused by parents, family environmental conditions, and the surrounding environment. Memilih jurusan yang akan ditempuh di perguruan tinggi dapat memunculkan keraguan bahkan kecemasan pada siswa tahun terakhir SMA. Ada berbagai faktor yang memicu keraguan dan kecemasan ini, khususnya bila memilih lintas jurusan. Lintas jurusan adalah keputusan memilih bidang ilmu yang akan ditekuni di perguruan tinggi, yang berbeda dengan bidang jurusan di tingkat SMA. Penelitian ini dimaksudkan untuk mendiskripsikan dinamika psikologis siswa yang memutuskan untuk lintas jurusan.  Penelitian ini menggunakan model deskriptif kualitatif berbasis studi kasus. Studi kasus dipilih agar penelitian ini mendapatkan data yang lebih rinci dan mendalam dari subyek partisipan. Teknik pengumpulan data yang digunakan adalah observasi dan wawancara. Hasil analisa menunjukkan adanya aspek emosional berkaitan dengan kecemasan dan keraguan yang dialami siswa ketika memilih jurusan pendidikan lanjut, yang disebabkan sejumlah faktor yaitu orang tua, kondisi lingkungan keluarga dan pengaruh lingkungan sekitar.

This research aims to compare the loneliness and hope among orphans in the Tanjung Barat orphanage, South Jakarta. The research method used a descriptive qualitative with a case study method. Data collection techniques were interviews, observations, and filling in a simple questionnaire. The sample used 36 children of Tanjung Barat orphanage consisting of elementary school, junior high school and senior high school students. This was done on site and compared to the literature that had been previously established.  Comparing loneliness and hope among orphans aimed to identify and find ways of mapping loneliness and hope among orphans who had been explored and investigated empirically, to find out the comparison and contrast with the mapping of loneliness and hope expressed among them, and to find examples of self-assessment to evaluate and encourage the mapping of their loneliness and expectations among them and present them to caregivers, parents and professionals. By comparing their loneliness and hopes they can actively engage in social interaction between themselves, others, and improve their personal, welfare and life skills.
