Critical thinking is a thinking process in processing information logically starti from understanding, analyzing, evaluating and making precise conclusions. Critical thinking indicators are clarification, assessment, inference, and strategy that referred to Jacob and Sam. Mathematics is designed to improve students' critical thinking in a solving problem. One of the factors that affect students' critical thinking in solving a problem is AQ. This research is descriptive study with qualitative approach. The aim is to describe critical thinking profile of climber, camper, and quitter students in solving mathematical problems. The subjects were three students of VIII grade junior high school who represented each AQ category and had good communication skills. The instrument used was the ARP questionnaire, mathematics problem solving tests, and interview guidelines. The results shows that students’ critical thinking profile in understanding the problem is climber and camper student do all indicators of critical thinking in the clarification phase. Quitter student is only able mentioning known and asked information. In devising a plan, climber student implements all indicators of assessment and strategy phase. Camper student implements all indicators in assessment phase, but do not discuss the possible steps in strategy phase. Quitter student does not do both assessment and strategy phase. In carrying out the plan, climber and camper students do all indicators of inference phase, while quitter student does not. In the step of looking back, only climber student who carries out evaluating steps that have been done. Keywords: Jacob and Sam’s critical thinking, mathematical problem solving, adversity quotient

<p>The ability to forgive others is a condition in which a person is able to change the negative influence and solve dissonance and distress that accompany some life events into something constructive and pleasant. One technique that can be used to improve forgiveness is the Value Clarification Technique. The purpose of this study is to find out whether value clarification techniques are effective in increasing the ability to forgive others in MTs students. The research method used was experimental research with the type of One group pretest-posttest design. The research subjects were 8th grade MTs Al-Urwatul Wutsqo Jombang which were selected by purposive sampling technique. The instruments used were the Enright Forgiveness Inventory (EFI) attitude scale, and the training guide used as training material. Data is analyzed by analysts at Wilcoxon Matched Pairs Signed Ranks Test. Based on the results of the study it can be concluded that the value clarification technique is effective to increase the ability to forgive others in MTs students. The suggestions for this  research are: (1) To get maximum results in the application of value clarification techniques, the counselor is expected to pay more attention to the cultural factors possessed by the subject, (2) Further researchers are expected to further deepen the research topic on self forgiveness (self-forgiveness/intrapersonal forgiveness), which is also a matter that needs attention, in order to maximize character education activities.</p><p> </p><p>القدرة على مسامحة الآخرين هي موقف سلبي ومضطرب يكون أحيانًا بناء وممتعًا. أحد الأساليب التي يمكن استخدامها لتحسين المغفرة هي تقنية توضيح القيمة. الغرض من هذه الدراسة هو معرفة ما إذا كانت تقنيات التوضيح فعالة في زيادة القدرة على مسامحة الآخرين في طلاب MTs. طريقة البحث المستخدمة هي البحث التجريبي مع نوع من تصميم الاختبار القبلي التجريبي. كانت الموضوعات البحثية هي MTs من الصف الثامن Al-Urwatul Wutsqo Jombang التي تم اختيارها بواسطة تقنية أخذ العينات الهادفة. كانت الأدوات المستخدمة هي مقياس اتجاه مخزون الغفران (EFI) ، ودليل التدريب المستخدم كمواد تدريبية. تحليل البيانات من قبل المحلل في ويلكوكون المتطابقة أزواج وقعت في المرتبة اختبار. بناءً على نتائج هذه الدراسة ، تم التوصل إلى أن قيمة تقنية التوضيح كانت زيادة القدرة على مسامحة الآخرين في طلاب MTs. الاقتراحات الخاصة بهذا البحث هي: (1) مزيد من المعلومات حول التقنيات المملوكة ، أهم العوامل التي يمتلكها هذا الموضوع ، (2) من المتوقع أن يواصل الباحثون المزيد من تعميق موضوع بحث عن المغفرة الذاتية (المغفرة الذاتية / المغفرة الشخصية) ، وهي أيضًا مسألة تحتاج إلى اهتمام ، من أجل تعظيم طابع الأنشطة التعليمية.</p>

Mathematics Problem

This study describes the profile of vocational high school students' metacognitive abilities in mathematics problem solving based on their logical thinking abilities. This research was conducted using descriptive research methods with a qualitative approach. The data was collected using a logical thinking ability test and problem-solving test and. Three students were selected who met different logical thinking stages: the abstract operation stage, the transition stage, and the concrete operational stage. The results showed the subject of the abstract operation stage fulfilled the metacognition stage by re-describing the given problem, knowing the relationship between what was known and what was asked, working on the problem by writing down what was known and asked and entering into the formula and also checking the answer. Transition stage subjects fulfill the metacognition stage by describing initial information and instructions, performing problem-solving steps, and counting to check completed work. The subject of concrete operations fulfills the metacognition stage by stating information and instructions that are non-specific and detailed. The subject has not been able to state the proper steps to ensure the information's conformity with the problem, and the subject sees what is done by calculating.

This study was conducted, first, analyzed to determine the learning styles of students excel in Mathematics and Science subjects in class XI SMAN 1 and MAN 1 Yogyakarta by applying the theory of David Kolb's learning style. Second, to predict the differences and similarities of learning styles of students achievement in learning Mathematics Class XI SMAN 1 and MAN 1 Yogyakarta. 18 research subjects were drawn from students of class XI. Determining the subject of research is done by using purposive sampling technique that refers to the result of the average value of UTS Mathematics which is the third highest of any class. The results showed that: (1). Students' learning styles achievement in Mathematics and Science subjects in class XI SMA N 1 and MAN 1 Yogyakarta is varied. This is evidenced by the results if the data obtained show that the student has a unique learning style of each and likely to lead to the individual's personality. Based on the analysis of student learning styles achievement shows that students SMA N 1 Yogyakarta been the subject of much research as 4 students have a learning style Assimilator, 3 students have learning styles Konverger, one student has a learning style Akomodator and one student has a learning style Diverger again. While students perform at MAN 1 Yogyakarta who is the subject of research, as many as four people have Akomodator learning styles, each two students have learning styles Assimilator and Diverger, then one student again has a learning style Konverger. (2). Differences in learning styles that happens is the individual habits that become unique to them. Students perform at SMA N 1 Yogyakarta dominates the Assimilator learning styles, while students of MAN 1 Yogyakarta dominates the Akomodator learning styles.

This study aims to describe and determine students' abilities to solve mathematical problems that focus on visual and auditory learning styles. Subjects are eighth-grade students from junior high school in Bulukumba district. This research is descriptive qualitative, which seeks to determine and describe the mathematical problem solving ability in terms of student learning styles. Data is collected using questionnaires, tests, and interviews. The use of questionnaires describes visual learning styles and auditory learning styles. Two numbers of the test determine mathematics problem solving ability in Polya's step, and interviews confirm mathematics problem solving ability. The data analysis techniques are reduction, presentation, and verification. Based on the results, the first subject with a visual learning style can fulfill all the indicators of Polya's steps, but another one is just three indicators. The first subject with an auditory learning style can meet all Polya's steps, but the other can fulfill three indicators.
