LKS is a teaching material that also plays an important role in improving the quality of learning. Preparation of the appropriate LKS and in accordance with the curriculum used is expected to achieve the learning objectives, so it needs continuous LKS development activities. The purpose of this research is to develop LKS based on Contextual Teaching and Learning (CTL) on linear equation system material three valid, practical and effective variables.This type of research development is Research and Development (R & D) with the ADDIE development model. Stages of the ADDIE development model consist of analysis, Design, Development, Implementation, Evaluation. The research instrument consists of Questionnaire and question instrument. Questionnaires consist of validation sheet by the material expert, validation assessment sheet by design expert, validation assessment sheet by media expert, individualized trial evaluation sheet, small group trial evaluation sheet, and evaluation field test sheet. while the question instrument consists of a pre-test and post-test questions. LKS developed, then validated by the validator. Validation results obtained LKS with revisions based on suggestions and comments validator. Validity is illustrated by the percentage of material expert, designer and media experts in 82,61% in \"highly valid\" category, 76,16% in \"valid\" category, 90% in \"very valid\" category. LKS was then piloted into three stages: individual trials with 3 medium and low-skilled students, small group trials with 6 students, and field trials conducted in the real classroom of class X MIA 2 with 34 students.

Mathematical critical thinking ability is a capability that supports a variety of other mathematical thinking abilities. The students' critical thinking ability is also closely related to the personality or character of the student. Personality can affect how a person behaves, thinks, or interacts with around. The personality types discussed in this study are examined from four types of temperaments by the theories of Hippocrates and Galenus. This research includes the type of qualitative research that uses descriptive qualitative research methodology. This research will be conducted on the students of class XI MIA SMA Negeri 2 Kota Jambi. The thing described in this research is the students' mathematical critical thinking based on the dominant personality type on linear program solution. The results of personality tests of the instrument adapted from the patterns of personality by Lana Bateman found 40 dominant students that is the type of phlegmatic personality. Furthermore, based on sampling technique that is purposive sampling technique, 2 students are taken as research subjects ie phlegmatic students with the highest level of critical thinking ability called first phlegmatic students and phlegmatic students with the lowest level of critical thinking ability is called second phlegmatic student. From the results obtained can be concluded that the first phlegmatic students have the level of critical thinking skills are very critical and the second phlegmatic students have a critical level of critical thinking is not critical. This is inversely between the ability to think critically and the type of phlegmatic personality. The first phlegmatic student with enough phlegmatic category has critical critical mathematical thinking and the second phlegmatic student with very high / dominant phlegmatic category, critical critical thinking ability is not critical.Keywords: Mathematical Critical Thinking Ability, Four Temperament Types","PeriodicalId":369390,"journal":{"name":"PHI: Jurnal Pendidikan Matematika","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126943674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability to think critically can encourage students to come up with new ideas or thoughts about a problem. Developing students' critical thinking skills can help students make conclusions by considering data and facts that occur in the field. This research is an experimental research with research design using experimental design Posttest Only Control Design. The population in this study is all students of class VIII SMPN 5 Kota Jambi consisting of eleven classes. While the sample is the students of class VIII C as the experimental class and class VIII J as the control class taken by random sampling.
