This study aims to obtain an overview of the characteristics and levels of metacognitive ability of junior high school students as seen from the melancholic and choleric personality types according to Hippocrates-Galenus. The results of this study are expected to be used as consideration for teachers in designing mathematics lessons that pay attention to personality types and students' metacognitive processes. A qualitative descriptive approach was chosen to answer the research objectives. At the same time, the research subjects were two grade VII students with melancholic and choleric personality types in one of the Muhammadiyah Junior High Schools in Jepara. The purposive sampling technique used in this research to subject selection. Data collection techniques used personality type questionnaires, metacognition tests, and interviews. Data analysis used three steps, namely data reduction, data presentation and conclusion drawing. The results showed that melancholic and choleric students had different characteristics and levels of metacognition. Melancholic students are at the metacognitive level between tacit use and aware use, while the rest of the cholerics are at the tacit use metacognition level. Penelitian ini bertujuan untuk mendapatkan gambaran tentang karakteristik dan jenjang kemampuan metakognisi siswa SMP yang dilihat dari tipe kepribadian melankolis dan koleris menurut Hippocrates-Galenus. Hasil penelitian ini diharapkan dapat dijadikan sebagai bahan pertimbangan guru dalam mendesain pembelajaran matematika yang memperhatikan tipe kepribadian dan proses metakognisi siswa. Pendekatan deskriptif kualitatif dipilih untuk menjawab tujuan penelitian.

Reasoning Abilities

The abilities that must be mastered by high school students according to the demands of the 2013 curriculum include reasoning. Students who have good reasoning abilities make it easier to understand mathematics. But in reality there are still many students who have low mathematical reasoning ability, seen when they have difficulty solving math problems. This research objective is to prove the habit of solving open-ended problems that can improve the mathematical reasoning ability of junior high school students based on the level of initial mathematical ability: high, medium, and low. The study used an experimental method with a "One-Group pre-test post-test design". Randomly, selected 77 grade VII students of SMP Negeri in Bekasi as a sample. The prerequisite test shows that each level of data comes from groups that are normally distributed and homogeneous. The results showed normal gain, both overall and level showed improvement. Based on the t test obtained p value of 0.000 < 0.005, meaning this study can prove student habits in solving open-ended problems when learning mathematics on triangles and quadrilateral, can improve students' mathematical reasoning abilities.

This research aimed to identify differences in problem solving skill between male and female students. The research subjects were 50 students (21 male and 29 female) who were taken by random sampling technique from two high schools in Malang. The research instrument was adapted from problem solving instruments of Maries & Singh (2018). The data was analyzed by statistic descriptive and Kruskall Wallis test (p-value <0.05). The results showed that overall, there was no significant difference between male and female students (p-value>0.05). However male students performed better than female students on preparing the action (p-value<0.05). The results of this research can be a consideration and input for practitioners of education to improve the quality of education, especially in Indonesia.
