Problem-solving and mathematical connections are two important things in learning mathematics, namely as the goal of learning mathematics. However, it is unfortunate that the ability of students 'mathematical connections is very low so that it impacts on students' failure in solving mathematical problems. The writing of this paper aims to discuss the understanding of mathematical problems, mathematical problem solving, mathematical connections, and how they play a role in solving mathematical problems. The method used in writing this paper is a method of studying literature, which is reinforced by the example of a qualitative research result. The research subjects consisted of two eighth grade students of junior high school in Jember East Java, Indonesia, in 2017/2018. The research data consisted of written test results solving the mathematical problem as well as interview results. Data analysis uses descriptive qualitative analysis. From the results of literature studies and research results provide a conclusion that mathematical connections play an important role, namely as a tool for students to use in solving mathematical problems where students who have good mathematical connection skills succeed in solving mathematical problems well, while poor mathematical connection skills cause students to fail in solving mathematical problems.

AbstrakKemampuan berpikir kritis dengan tahapan focus, reason, inference, situation, clarity, dan overview serta kemampuan daya juang (adversity quotient) memiliki peranan sangat penting dalam aktivitas memecahkan masalah matematika. Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir kritis siswa dalam menyelesaikan masalah ditinjau dari adversity quotient (AQ). Penelitian deskriptif kualitatif ini dilakukan di sebuah SMP di Jember, Indonesia, pada bulan September 2021. Pengumpulan data menggunakan metode angket Adversity Response Profile (ARP), tes tertulis berpikir kritis, serta wawancara. Hasil pemberian angket ARP kepada 31 siswa kelas IXB, diketahui ada 10 siswa dengan tipe climber, 18 siswa dengan tipe camper, dan 3 siswa dengan tipe quitter. Dari tipe AQ tersebut dipilih enam siswa dengan 2 siswa tipe climber, 2 siswa tipe camper, dan 2 siswa tipe quitter untuk mengikuti tes tertulis dan wawancara. Triangulasi menggunakan triangulasi metode, yaitu mencari kesesuaian antara data dari hasil tes tertulis dengan wawancara. Hasil penelitian menunjukkan bahwa siswa dengan tipe climber memenuhi seluruh kriteria berpikir kritis FRISCO, yaitu focus, reason, inference, situation, clarity, dan overview. Siswa dengan tipe climber mampu menyelesaikan permasalahan yang diberikan dengan tepat waktu dan mengecek kembali jawaban. Siswa dengan tipe camper dapat memenuhi 5 dari 6 kriteria berpikir kritis FRISCO, yaitu focus, reason, inference, situation dan clarity. Siswa dengan tipe camper mampu menyelesaikan permasalahan yang diberikan tepat waktu. Kekurangannya adalah siswa camper tidak melakukan overview, yaitu tidak mengecek kembali jawaban sesudah menyelesaikan masalah. Adapun siswa dengan tipe quitter hanya mampu memenuhi 2 dari 6 kriteria berpikir kritis FRISCO, yaitu mereka hanya mampu melakukan focus, dan clarity, serta kesulitan memahami permasalahan sehingga tidak dapat menyelesaikan masalah tersebut. Dari hasil ini, maka guru perlu memberikan motivasi kepada siswa untuk mempunyai daya juang tinggi agar memiliki kemampuan berpikir kritis tinggi dalam memecahkan masalah matematika.AbstractCritical thinking skills which include the stages of focus, reason, inference, situation, clarity, and overview as well as the ability to fight (adversity quotient) have a very important role in solving mathematical problems. This study aims to describe students' critical thinking skills in solving problems in terms of the adversity quotient (AQ). This descriptive qualitative research was conducted at a junior high school in Jember, Indonesia, in September 2021. The data was collected using the Adversity Response Profile (ARP) questionnaire, a written critical thinking test, and interviews. The results of giving ARP questionnaires to 31 students of class IXB, it is known that there are 10 students with the climber type, 18 students with the camper type, and 3 students with the quitter type. From the AQ type, six students were selected with 2 climber type students, 2 camper type students, and 2 quitter type students to take written tests and interviews. Triangulation uses the triangulation method, which is to find a match between the data from the results of the written test and the interview. The results showed that the climber type students met all of the FRISCO critical thinking criteria, namely focus, reason, inference, situation, clarity, and overview. Students with the climber type are able to solve the problems given in a timely manner and recheck the answers. Camper type students can fulfill 5 of 6 FRISCO critical thinking criteria, namely focus, reason, inference, situation and clarity. Camper type students are able to solve the problems given on time. The drawback is that camper students do not do an overview, that is, they do not re-check the answers after solving the problem. As for students with the quitter type, they are only able to meet 2 of the 6 criteria for FRISCO critical thinking, namely they are only able to focus and clarity, and have difficulty understanding problems so they cannot solve the problems. From these results, the teacher needs to motivate students to have a high adversity quotient in order to have high critical thinking skills in solving mathematical problems. Keywords: Adversity Quotient, Critical Thinking, Mathematical Problem Solving.

Mathematical communication skills are important for students to have, but these abilities are still low. One reason is that the teacher's teaching method is still dominated by lectures in the classroom. This study aims to improve students' mathematical communication skills through the development of learning tools using the outdoor learning method on sequences and series material. Validation sheets, observation sheets, student response questionnaires and learning achievement tests are the data collected for analysis. The results of the validity of lesson plans, worksheets, and THB each reached a value of 4.6; 4.7; and 4.6 out of a maximum value of 5, which means it is valid. The results of the practicality analysis of the device reach 92%, which means it is practical. From the trial results, there were 80% of students in the active category, and positive student responses reached 84%. The minimum completeness of the learning outcomes test was obtained by 85.29% of the students in the experimental class, while the control class only reached 52.94%. From the results of the t-test it is evident that learning on sequences and series material with learning devices using outdoor learning methods has a significant effect on improving students' mathematical communication skills.
