Abstract. Critical thinking ability is a Students’ thinking ability in solving questions based on some components of Paul’s and Elder’s critical thinking with indicators used in this research is reasoning element (information, concept, idea, conclusion, and point of view) and reasoning intellectual standard (clear, appropriate, careful, relevant, deep, logical, and wide). The purpose of this research is to describe students critical thinking ability in solving arithmetic sequence and series questions in SMAN 5 Jember. The subject of this research was taken from 29 students of X MIPA 4 were categorized into 3 groups which are high, medium, and low ability based on their mathematic scores in the first semester. Based on the result of the critical thinking ability test and the interview, two subjects which were taken from low ability students were categorized as TKBK 0 (not critical). Three subject which were taken from medium ability students, one subject was categorized as TKBK 1 (less critical) and two subjects were categorized TKBK 2 (critical enough). One subject which was taken from high ability students was categorized as TKBK 3 (critical). From the result of the research, the subject is only able to reach critical level (TKBK 3) and 5 of the other subjects are still in the low critical thinking level which are TKBK 2, TKBK 1 and TKBK 0. Keywords: Critical Thinking Ability Level, Arithmetic Sequence and Series, Students’ Beginning Ability

This study aims to identify students’ misconception in terms of mathematics anxiety level. The type of this study was descriptive research with qualitative approach. The methods of data collection in this study used questionnaire, test, and interview. The subjects of this study were VIIIA grade students of Islamic Junior High School 2 Banyuwangi. Students’ test results are analyzed using four-tier diagnostic test to determine students understand the concept, do not understand the concept, and misconception. All students who have low mathematics anxiety level tend to understand the concept, students who have high mathematics anxiety level tend to do not understand the concept, while students who have middle mathematics anxiety level identified as misconception, but there were some who do not understand the concept and also understand the concept. Students’ tes results who identified as misconception were analyzed according to indicators of misconception. In this study the percentage of each form of students’ misconception to solve TIMSS problems with the total 31 students, 29% translation misconception or as many as 9 students, 16.1% of operation misconception or as many as 5 students, 29% of calculate misconception or as much 9 students, 16.1% systematic misconception or as many as 5 students, 12,9% concept misconception or as many as 4 students, and 22.6% of strategy misconception or as many as 7 students.

Abstract This research raises the problem of students' problem solving abilities in solving arithmetic sequence and series problems based on the theory of APOS (Action, Process, Object, Schema) in terms of the type of Florence littauer personality. Data collection was obtained from personality type questionnaires, problem solving tests, and interviews. The subject of the study came from 4 students of class XI TKJ 1 of SMK Negeri 2 jember using the snowball sampling method to classify 4 personality types which include sanguinis, koleris, melancholy, and phlegmatic. The results of the analysis of problem solving ability tests and interviews showed that at the stage of action, sanguinis (SS) students could explain smoothly and complete the lack of data on the answer sheet. Koleris students (SK), explained fluently and consistently, melancholy students (SM) could explain correctly even though in answering questions they were still hesitant. Phlegmatic students (SP) are fluent and assertive when explaining the information in the question again. At the process stage, students of SS, SK, SM, and SK managed to find a number pattern and could determine the formula to solve the problem. At the object stage, the four subjects managed to answer correctly even though they used different problem solving processes. At the scheme stage, SS students, SK, SP managed to give the final answer correctly and tried to check the answer again, while the SM students had not managed to answer correctly. Keyword: problem solving, theory of APOS, personality type

Abstract. Mathematical representation is an ability of people to re-express their interpretation about their understanding of a problem. In the practice of learning, students frequently could not represent their own mathematical interpretation. It is caused by many factors, for instance, physical limitations owned by students with visual impairment. In this study, it would be described about mathematical representative in the form of written text, mathematical expressions, verbal representations, and visual representation in understanding the concept of triangles. Therefore, the type of the research is decriptive research with qualitative approach. The subject of the study is 3 students with visual impairment in VII grade in SMPLB-A TPA Jember. The description of mathematical representation of blind students are adjusted to the level of thinking based on Van Hiele theory. Van Hiele divides students' level of thinking into 5 levels: visualization, analysis, informal deduction, deduction, and rigor. The three subjects conduct test of thinking level based on Van Hiele theory, mathematical representation test, and interview. The level category of students’s thinking is figured out through Van Hiele theory. Mathematical representation test is used to comprehend mathematical representation by using written text which containst the written explanation of the subjects towards the triangles and mathematical expression about how the subjects solve the problems of the triangles by using mathematical model. Meanwhile, the interview is used to know the verbal representation which contains the oral explanation about triangle concept and visual representation about how the subject creates the triangle. Keywords: Mathematical representation, visual impairment student, triangle, Van Hiele theory

This research aims to describe the profile of the students’ ability in solving mathematics problem in terms of personality according to David Keirsey which includes guardians, artisan, idealists, and rationales. The research subject is four students who are obtained from one student of each personality type in SMKN 2 Jember. MBTI questionnaire, problem-solving test, and interview are used as the data collection method. The analysis of problem-solving test and interview shows that in the stage of understanding and planning the settlement all students are able to fulfill this stage. In the stage of carrying out the plan, SG, SA, and SI students bring about the plan that is made before, while SR student tend to do it based on their remembering skill and it is not appropriated with the existing formula. In the stage of re-checking, only SA and SI students always recheck the steps of processing along with the obtained result. However, SG and SR students do not recheck their work. Besides, SA and SI students have more than one alternative solutions. Keywords: Polya Phases, Personlaity, MBTI
