This research is based on the level of mathematical reasoning ability and Self confidence which is owned by Students who are still relatively low. then the purpose of this study are: 1) to know the level of students' reasoning ability seen from the achievement of minimum mastery criteria (KKM); 2) to know the students' perceptions of each indicator of mathematical reasoning ability; 3) to know the level of Self confidence categories of students on each item statement. This research uses qualitative approach with explorative descriptive method. Subjects in this study were students of class XI IPS1 which amounted to 20 students in SMA Putra Juang academic year 2017/2018. The research instrument consisted of test question instrument, non test instrument in the form of questionnaire, and interview guide. From the research, it is found that the reasoning ability and self confidence of XI IPS1 SMA Putra Juang class students on the opportunity material are included in low category. This can be seen from the test results where the value of Students 75% below KKM and only 25% above KKM.Serta from the questionnaire that shows the ability of self-confidence mathematics owned 50% low students, 25% Medium, 20% High, and 5 % very high. whereas students 'misconception in reasoning ability occurs in many indicators of students' ability to construct and test a conjecture in mathematics lessons, where only 5 students reach this indicator of ability.

This study aims to determine the increase in mathematical dispositions of students using the open ended approach. The method used in this study is a qualitative method and this type of research is classroom action research. The population of this study was all students of class X IT Development Vocational School while the sample was class X RPL B. Data were collected based on observations, notes in the field, instruments in the form of non-disposition mathematical questionnaire scale tests. Questionnaires given contain indicators of students' mathematical dispositions, namely (1) confidence (2) can express ideas (3) check back on work results (4) persistent and diligent when working on questions (5) enthusiasm and serious learning mathematics (6) expect metacognition. The results of this study indicate that the use of an open-ended approach in mathematics learning can improve the mathematical disposition of class X RPL B students without development.

This research is based of low mathematics creative thinking ability from students in Vocassional High School in order to be needed study method to solve that problem. Alternatife of study method and strategy is use Mind Mapping method by Thinking Aloud Pair Problem Solving (TAPPS) strategy. The purpose of this research is to identify weather achievement of mathematics creative thinking ability of students in High School through use Mind Mapping method by Thinking Aloud Pair Problem Solving (TAPPS) strategy is better than use convensional study. The population in this study were vocational high school students in Bandung, while the sample was SMK MAARIF Cicalengka and selected two classes randomly from all of the existing XI class. Then from the two classes are assigned randomly into the experimental class and control class. The experimental class received learning get Mind Mapping Method by Thinking Aloud Pair Problem Solving (TAPPS) strategy and control class gained regular learning. The instrument used is the test of creative thinking ability mathematically. Based of the calculation and hypothesis test concluded that the achievement of creative thinking ability of mathematic of students who get Mind Mapping Method with Thinking Aloud Pair Problem Solving (TAPPS) Strategy is better than those who get regular learning.
