“…Penelitian ini dibatasi oleh fokusnya, kriteria spesifik untuk memastikan validitas data, dan desain sementara. Juga, data kualitatif dihasilkan melalui keputusan bersama (Tohir & Wardani, 2017;Tohir, Susanto, Hobri, Suharto, & Dafik, 2018;Tohir, 2019b;Erviana, 2019). Menurut Saryono (Syarifah, 2017;Hadi & Faradillah, 2018;Ruswana, 2019) mengatakan bahwa penelitian kualitatif adalah penelitian yang digunakan untuk menyelidiki, menggambarkan, menjelaskan, menemukan kualitas atau keistimewaan dari pengaruh sosial yang tidak dapat dijelaskan, diukur atau digambarkan melalui pendekatan kuantitatif.…”

Descriptive analysis methode of research describes about increasing subject in the level of critical thinking skills of students in solving mathematics based on 21st-century skills. The subjects research were 28 students of Mathematics Education Study Program at Ibrahimy University of Situbondo. Data collection is done by providing pre-test and study documentation to students. The test is given to collect data related to students' critical thinking skills. Then learning is done based on 21st-century skills. Furthermore, students are given a post-test solving mathematical problem. Data were collected through observations, test results and interview data tested for their validity by triangulation. The data analysis technique used is qualitative descriptive data analysis. The results of this study indicate that: (1) the results of the achievement of indicators of critical thinking of students based on critical thinking stages formulated by Facione, overall the subject of an increase of 7.53%; (2) there was the same highest increase in the achievement of the indicator thinking Facione stage, namely at the Analyze stage (A) for high, medium, and low category subjects respectively, 77.78%, 80%, and 44.44%. However, there are still two stages of critical thinking that still need attention for further research, namely at the List (L) and Self-Correct (S) stages classified as still needing special attention in implementing 21st-century skills in learning activities; (3) the level of critical thinking skills of students based on the critical thinking stages formulated by Facione was in the category of "not critical" for the pre-test results and was in the category of "sufficient critical" for the post-test results.

“…Selain itu, Demercioglu, Argun, & Bulut (2010), juga menjelaskan bahwa kemampuan pemecahan masalah matematika merupakan jantung dan tujuan umum dalam pembelajaran matematika. Pemecahan masalah juga dijelaskan oleh Polya (Hobri, 2009;Tohir, Susanto, Hobri, Suharto, & Dafik, 2018) sebagai suatu upaya dalam mencari jalan keluar atau solusi dari kesulitan-kesulitan yang sedang dihadapi untuk mencapai suatu tujuan yang tidak dapat segera bisa dicapai. Tahapan-tahapan pemecahan masalah matematika, secara garis besar dapat dibagi menjadi empat tahap, yaitu:…”

“…Materi yang digunakan pada penelitian ini adalah aljabar dengan masalahmasalah yang mendukung level kesulitan soal pada kategori tinggi. Tahapan pemecahan masalah pada penelitian ini mengacu pada tahapan pemecahan masalah Polya (Tohir et al, 2018). Hasil pada penelitian ini diharapkan dapat memberikan informasi terkait self efficacy siswa climber terhadap kemampuan pemecahan masalah matematika berlevel tinggi, dengan tahapan Polya.…”

This research aims to describe about the profile of climber students’ self efficacy to the problem solving skills of high level mathematics problems. It is including form of descriptive research with qualitative approach. The research subjects are 13 climber students in class XI MIPA 8 of SMA Negeri 1 Jember, were tested by Adversity Response Profile (ARP) questionnaire. The method of data collection use a test of problem solving skills of high level mathematics problems, adversity response profile (ARP) questionnaire and interviews. The results of this research showed that the climber students are tend to have high self efficacy and able to by every Polya’s stages.

“…Menurut Tohir (2017) mengatakan bahwa masalah matematika adalah suatu masalah yang membutuhkan teknik tertentu untuk memecahkannya baik berupa soal rutin maupun non rutin. Oleh karena itu perlu dikembangkan kemampuan praktis matematika seperti pemecahan masalah, membuat hubungan, memahami berbagai representasi dari ide-ide matematika, mengkomunikasikan proses pemikiran mereka, dan penalaran (Tohir, Susanto, Hobri, Suharto, & Dafik, 2018).…”

The Trending topic in International Mathematics and Science Study (TIMSS) and the Program for International Student Assessment (PISA) have become a new standard for mathematics learning. One of the objectives of the study from TIMSS and PISA is to know the students' abilities in reasoning, identifying, and understanding, and using the basic mathematics needed in daily life. Or in other words, students must have mathematical literacy. The concept of mathematical literacy is intended the ability of individuals to formulate, use, and interpret mathematics in various contexts. This includes mathematical reasoning and using mathematical concepts, procedures, facts, and equipment to describe, explain, and predict phenomena or events (OECD, 2013). Indonesia has participated in TIMSS and PISA studies several times, from the TIMSS and PISA study results, it shows that students have not been able to develop optimally about their thinking abilities in mathematics schools and are still low in ability (1) to understand complex information, (2) theory , analysis and problem solving, (3) using tools, procedures and problem solving and (4) conducting investigations. In 2014, the National Council of Teachers of Mathematics (NCTM) stated that learning mathematics today is still too formal, lacks connection with the meaning, understanding, and application of mathematical concepts, and fails to give sufficient attention to the ability of reasoning and solving problem. These results indicate that there needs to be a change in curriculum orientation, which is not to burden students with content but prioritize the aspects of essential abilities needed by all citizens to participate in developing their country in the 21st century. Therefore it is necessary to develop a mathematics curriculum that enhances students' abilities in reasoning and problem solving in order to improve the quality of mathematics for students knowledge and skill in this global era.
