“…This model's reason is that the learning process shall increase problem-solving too and eliminate students' cognitive load. (Fitriadi et al, 2017;Mikrayanti, 2012;Sumartini, 2016 Based on the background above, the research problems are: (1) How are the students' problem-solving skills when using a problem-based learning model modified by cognitive load theory? (2) Are its skills better than a general problem-solving model?…”

The background of the research is based on the fact that problem solving skills and its process is still low so that those create overload information. Another way to overcome this problem is to use a problem-based learning model which concerns on cognitive load theory. This study is aimed to determine on how students' problem solving skills when using a problem-based learning model modified by cognitive load theory. This research method uses a combination of research methods, namely quantitative as primary data and qualitative as secondary data. The population in this study are all students of grade VII Junior High School accredited A in Tangerang Regency. The sampling technique used is cluster random sampling and the selected sample is 60 students of Grade VII SMP Negeri 3 Cikupa which divided into experimental class and control class. The instruments in this research are 5 short essay tests and non-tests, questionnaire and interview. Based on data analysis’ result, it can be concluded that the achievement and improvement of students' mathematical problem solving abilities which use problem-based learning model modified by cognitive load theory is better than for those using problem-based learning generally.

“…The ability of mathematical reasoning has an important role that is in line with the mathematical vision for the fulfillment of future activities (Eni et al, 2018). Russefendi said this is because mathematics is a result formed from human thinking ability related to reasoning, ideas and processes (Mikrayanti, Baeti, & Wirahmat, 2019). But until now students' mathematical reasoning ability has not reached the expected stage, this has caused students' inability to solve mathematical problems One of the causes of students' lack of reasoning power is in the course of learning mathematics, students are only introduced by the teacher regarding formulas and concepts that are carried out orally without any understanding of where the formulas and concepts come from.…”

Self-confidence is an aspect of personality that plays a role in shaping the potential of students, if they master the confidence with slick, it is also expected to pursue their mathematics to produce optimal results, so that this aspect also has an influence as an important role in the ability of mathematical reasoning students. This study has the intention to see the effect of student confidence on the mathematical reasoning ability of Grade IX students of SMPN 11 Bekasi semester 1 of the 2022-2023 academic year. The proposed research method is quantitative research techniques with survey research design. The sampling technique used is Simple Random Sampling. The population of Class IX was 237 students. Samples were taken as many as 149 students using the Slovin formula. The research Data was obtained through testing instruments about mathematical reasoning ability as much as 5 points and instrument questionnaire confidence as much as 20 statements. The results obtained can be concluded in the form of self-confidence affect the reasoning ability of students. Self-confidence had a positive effect of 3.4% on students ' reasoning ability. however, students ' self-confidence is still at a moderate level. So, the reasoning ability of students cannot be said to be optimal. Based on the results found, it is necessary to conduct extended research on this theme by using various other influencing factors.

“…So it is easy for extrovert students to convey their ideas or thought to other students or teacher. This is based on the statement which underlines that mathematical communication skills happen when students learn in groups (Asnawati, 2017;Mikrayanti, 2012;Syasri et al, 2018).…”

The purpose of this study is to determine mathematical communication skills that assessed from introvert and extrovert personality types, to determine the strengths and weaknesses of each personality type. This research is a qualitative descriptive study. The class subjects are students of SMA Kartika III-1 Banyubiru, grade XI MIPA 2 (Mathematics and Natural Science). The subjects of the research are 2 introvert and 2 extrovert personality types' students. The procedures of collecting data are written tests, interviews, questionnaires and documentation. The results of this study show that mathematical communication skills in terms of introvert personality type are able to meet 1 indicator. That is the ability to explain ideas, situations and mathematical relations in writing. In contrast, the extrovert personality type meets 2 indicators of mathematical communication skills. There is the ability to express daily events in language or mathematical symbols and the ability to read mathematical symbols. The strengths of introvert personality type are able to explain ideas verbally and in writing. Then the weaknesses are difficult to understand the problem of mathematical images and symbols. In contrast to the introvert, extrovert personality's strengths are able to understand mathematical symbols, and then its weaknesses are hard to understand mathematics questions.
