Relational understanding is conceptual understanding that focuses on the interrelationships between concepts. The initial research conducted in the class of XI-Grade/Natural Sciences of the SMA Nasional Malang showed that students still had a low relational understanding. The results of observation of learning activities also show that learning activities do not support the relational understanding of students. Classroom action research was carried out to provide a solution to the problem by applying the TPSS type of the cooperative learning model. There are two cycles in this study, each of which consists of planning, implementation, observation, and reflection. Indicators that the research is successful are: (1) in the last cycle test, the four indicators that have been determined of the students’ relational understanding appear; and (2) the application by the observer of the TPSS type of the cooperative learning model is given the value, at least, “Good”. This study was declared successful after the second cycle. The steps of the TPSS type of the cooperative learning model are: (1) Think; (2) Pair; (3) Square; and (4) Share. Pemahaman relasional adalah pemahaman konseptual yang berfokus pada keterkaitan antar konsep. Penelitian awal yang dilaksanakan pada kelas XI IPA 1 SMA Nasional Malang menunjukkan bahwa peserta didik masih memiliki pemahaman relasional yang rendah. Hasil observasi kegiatan pembelajaran juga menunjukkan bahwa kegiatan pembelajaran belum mendukung pemahaman relasional peserta didik. Penelitian tindakan kelas dilaksanakan untuk memberikan solusi dari masalah tersebut dengan menerapkan model pembelajaran kooperatif tipe TPSS. Terdapat dua siklus dalam penelitian ini yang masing-masing terdiri atas perencanaan, pelaksanaan, pengamatan, dan refleksi. Indikator keberhasilan dalam penelitian ini yaitu: (1) hasil tes akhir siklus peserta didik dapat memenuhi empat indikator pemahaman relasional yang telah ditentukan; dan (2) keterlaksanaan model pembelajaran kooperatif tipe TPSS berdasarkan hasil observasi aktivitas guru dan peserta didik oleh observer memperoleh nilai dengan kategori minimal “Baik”. Penelitian ini dinyatakan berhasil setelah dilakukan siklus kedua. Langkah-langkah model pembelajaran kooperatif tipe TPSS adalah: (1) Think; (2) Pair; (3) Square; dan (4) Share.

Argumentative ability can be seen from the argumentation pattern that appears. This pattern needs to be evaluated to look over the quality of the argumentation to make the right problem-solving. This evaluation can be done by recognizing the components that make up the argument. This study goals to describe students' argumentation abilities in solving statistical problem based on Adversity Quotients (AQ). This qualitative descriptive research elaborated 39 students taking a statistical methods course. Subjects were grouped into three types of Adversity Quotient based on the ARP (Adversity Response Profile) questionnaire results. Data were obtained using statistical problem tests and interviews. The outcomes showed three levels of AQ found in students, namely Camper, Toward Climber, and Climber. Camper-type students bring up the Claim-Data-Warrant pattern. Students with AQ levels towards climbers tend to have the same pattern as the Camper type. In comparison, students with the AQ Climber type have a Claim-Data-Warrants-Backing pattern. Based on the outcomes of the study, it can see that students' argumentation skills are determined by the Adversity Quotient level they have when solving statistical problems.
