Teaching approach applied by mathematics teacher can affect students' mathematical connection ability (MCA). The fact shows that there are still many teachers using conventional learning, causing ...passive students and low MCA among students. The purpose of this study was to describe the effectiveness of applying a collaborative realistic mathematics education (RME) approach using the classroom and the outdoor environment to improve students' MCA on the topic of similar triangles. This quasi-experimental research with a qualitative descriptive approach took the subject of ninth-grade students at a public junior high school in Jember, Indonesia. Data were collected using observation sheets, questionnaires, tests, and interviews. The data were analyzed using the effectiveness test (N-gain score). The results showed that the application of collaborative RME using the indoor and outdoor classrooms made students more active in physical, social, and mental activities. This learning is effective in improving students' MCA. The average score of 57.47 in the pre-test increased to 93.88 in the post-test, and the N-gain score was 0.86. Mathematics teachers are advised to apply this learning approach, not only on the topic of similarity triangles, but also on other suitable topics.
Kemampuan berpikir kritis dan Adversity Quotient (AQ) berperan penting dalam proses menyelesaikan masalah matematika. Penelitian ini bertujuan untuk mengetahui kemampuan berpikir kritis siswa SMA ...berdasarkan Adversity Quotient (AQ) pada materi sistem persamaan linear tiga variable (SPLTV). Jenis penelitian ini adalah deskriptif dengan pendekatan kualitatif. Instrumen yang digunakan berupa angket ARP, soal tes, dan pedoman wawancara. Angket ARP diberikan kepada tiga kelas di sebuah SMA Negeri di Jember, Indonesia. Dari 3 kelas tersebut dipilih 7 subjek penelitian, di mana 3 siswa dengan kategori AQ tinggi, 3 siswa AQ sedang, dan 1 siswa AQ rendah. Kemudian, mereka diberikan masalah matematika topik SPLTV untuk mengetahui kemampuan berpikir kritis siswa. Hasil penelitian menunjukkan bahwa siswa dengan kategori AQ tinggi cenderung mempunyai kemampuan berpikir kritis sangat tinggi dan tinggi. Siswa kategori AQ sedang cenderung mempunyai kemampuan berpikir kritis tinggi dan sedang, serta siswa kategori AQ rendah cenderung memiliki kemampuan berpikir kritis yang sangat rendah. Saran untuk siswa perlu meningkatkan AQ agar mampu memiliki kemampuan berpikir kritis yang optimal.
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.

This study aims to describe the students’ mathematical connections in terms of the locus of control. The mathematical connection indicators in this study are writing down the mathematical concepts ...that underlie the answers, recognize the relationship of various mathematical ideas and mathematical topics that can be related to problems of everyday life, and understand how to solve mathematical ideas that are interrelated and underlie each other to obtain an integrated whole. Data collection methods in this study were questionnaires, tests, and interviews. The subjects of this study were six seventh-grade students at MTs Negeri 7 Jember. The data analyzed by qualitative descriptive analysis. Based on the tests and interviews analysis, we known that students with internal locus of control could write mathematical concepts as a two variable linear equation system (TVLES). Students can connect TVLES material with problems, for example, represented the object in variables x and y. Students can also solved the problems related to TVLES material by using common examples, elimination and substitution methods. While the students’ with external locus of control also can write the mathematical concepts as a TVLES. But the students did not write in detail the relationship between TVLES material and the problem. Students can not solve problems by using TVLES solutions such as elimination and substitution, but students only use estimates in finding solutions.

Mastering mathematics in elementary school is essential for students because it provides the foundation to learn the subject at the secondary school and university levels. This study aimed to examine ...the effect of implementing the Outdoor Learning in Mathematics (OLM) method to increase elementary students' motivation and learning achievements in geometry. This study was carried out at one of the public elementary schools in Jember, East Java, Indonesia using an experimental research design. Participants were 54 grade 4 students consisting of class 4A and 4B, equally divided into the experimental and control groups, respectively. The experimental group was treated in the form of learning geometry topics using the OLM method, while the control group used conventional methods. Data were collected using questionnaires, observation, and tests. The obtained data were analysed using non-parametric statistics with SPSS software. The results showed that students' opinions were very positive and supported the application of the OLM method in elementary schools. In addition, the OLM method triggers the students' motivation, as well as student learning achievements in geometry. Thus, it can be concluded that the Outdoor Learning method has a positive effect on elementary students' motivation and learning achievement in geometry. From these results, it is necessary to conduct further researches involving a large number of participants, develop teacher modules, and incorporate the OLM method into the mathematics curriculum. It is hoped that students will like mathematics more, so that their motivation and learning achievements can be improved.
