Abstract:
The research is a qualitative descriptive research, the purpose of this research is to analyze students reflective thinking ability in terms of learning style. learning style in this research consists of three types namely visual, auditorial, and kinestetik. The subjects of the study were class VIII in one of the middle schools in Serang district selected by purposive sampling. Based on the analysis results obtained description of students' reflective mathematical thinking ability as follows: (1) Visual students have been able to provide interpretation but not yet complete and correct calculation; (2) Auditorial and kinesthetic students are able to provide correct interpretation and calculation. (3) In identifying the concept, visual students have been able to identify the formulas, auditorial and kinesthetic students have not been able to. (4) In evaluating/checking the validity of visual and auditorial students is already capable while kinestetik yet. (5) In distinguishing between relevant data visual and auditorial students have been able, and kinesthetic students have not been able. (6) In drawing the analogy of two cases, visual, auditorial, and kinesthetic students have not been able to. (7) In harmonizing with reason, visual, auditorial and kinesthetic students have not been able.

Abstract:
This research is to prove whether the learning result of Student Mathematics with cooperative learning model of TPS type is better than the result of student learning of Mathematics with STAD type cooperative learning model on tangent material of circle. The population is the students of State Junior High School 1 East Cikarang. The sample was taken by using cluster random sampling technique from the population by randomized method, ie students of class VIII F and class VIII G as many as 60 students. The analysis test is done by normality test and homogeneity test. Normality test using Lilliefors test and Homogeneity test using Fisher test. While the hypothesis test using t-test. Based on the calculation obtained data that Lilliefors model of cooperative learning model type TPS Lhitung = 0.0954 and for Ltabel = 0.161 (0.0954 < 0.161) and for cooperative learning model type STAD = 0.1266 and for Ltabel = 0.161 (0, 1266 < 0.161), so it can be concluded that the cooperative learning model of TPS type and STAD type cooperative learning model come from the normally distributed population. Homogeneity test using Fisher test obtained Fhitung = 1.15 and Ftabel = 1.86 (1.15 < 1.86) so that TPS and STAD homogen. Hypothesis testing obtained thitung = 2.388 and ttable = 1.651. Because thitung > ttable then H0 is rejected. The conclusion of this research is there are difference of mathematics learning result of students using cooperative learning model of TPS type and mathematics learning result of students using STAD type cooperative learning model in tangent circle material in class VIII SMPN 1 Cikarang East Bekasi.

Abstract:
Perkembangan ilmu pengetahuan, teknologi dan kebutuhan masyarakat menjadi pendorong lahirnya kebijakan pendidikn tinggi yang beroreintasi kepada kompetensi lulusan baik aspek pengetahuan,sikap maupun keterampilan. Seiring dengan perubahan oreintasi perguruan tinggi akan pencapaian tujuan pembelajaran yang diperoleh melalui internalisasi pengetahuan, sikap, ketrampilan, kompetensi, dan akumulasi pengalaman kerja. Untuk menjawab kebutuhan tersebut maka Kerangka Kualifikasi Nasional Indonesia, yang selanjutnya disingkat KKNI, menjadi suatu pilihan dalam meningkatkan kualitas hasil dan produk pendidikan tinggi. Dengan demikian KKNI merupakan suatu upaya yang sangat strategis untuk meningkatkan mutu lulusan Perguruan Tinggi baik skala Nasional maupun Internasional. KKNI ini sudah dirancang sejak tahun 2014, sehingga implementasi kurikulum KKNI ini perlu dilakukan penelitian sekaligus sebagai evaluasi, apakah kurikulum ini terlaksana atau tidak, hambatan apa yang dihadapi dan pencapaian apa yang diperoleh oleh para peserta. Sebagai hasil penelitian menunjukan bahwa : Implemenatasi kurikulum KKNI di prodi matematika, dilakukan melalui 3 tahap yaitu perencanaan, pelaksanaan dan tahap evaluasi. Pada tataran implementasi KKNI di prodi matematika belum berjalan secara baik, hal ini dikernakan sumber daya manusia yang belum mamahami, sarana prasarana yang kurang dan aspek kebijakan pimpinan yang belum mengeluarkan keputusan tentang berlakunya KKNI. Oleh karena itu usaha yang dilakukan oleh pihak prodi melalui kegiatan worshop dan seminar, sosialisasi sampai pada tingkat implementasi dalam proses pembelajaran perlu dilakukan.

Abstract:
The sociomathematics’ norm is a social norm of mathematical nuance, with sociomathematics’ norms; the social intelligence possessed by learners can be developed because this norm is strongly associated with negotiation and interaction. The purpose of this article is to know the improvement of sociomathematics’ norms student of mathematics education by using cooperative learning of Team Accelerated Instruction. This research uses pretest-posttes control only group design. Sample size in this research is 38 people in class C of course of Numerical Method taken by cluster random. The sociomathematics’ norm is obtained using an observation sheet. The data obtained were analysed using N-gain and t-test (paired-samples T Test). The calculation result shows that the pre-test average of 8,526, post-test, significance coefficient of 0.000, and N-Gain mean equal to 0,5. Based on the result, it can be concluded that the learning model of Team Accelerated Instruction can improve students' sociomathematics’ norm ability through numerical method.

Abstract:
This article aimed to find out the development of teaching materials in the form of modules by using Knisley's mathematical learning model on the subject of decent, interesting, and effective linear transformation used in lectures in Linear Algebra. The test subjects in this study were third semester students of Raden Intan Lampung State Islamic University. This research method is Research and Development (R & D) that uses the ADDIE Model (Analysis, Design, Development, Implementation, and Evaluation). The results of the expert assessment are feasible to use with an average score of 3.00 from material experts and 3.08 from media experts. The response of students in small group trials is interesting with an average score of 2.92, whereas in the trial of a large group the criteria are very interesting with an average score of 3.27. The results of the n-gain calculation at the pretest and posttest are 0.70 included in the high effectiveness category. Therefore, it can be concluded that the linear transformation module using Knisley's mathematics learning model is categorized as feasible, interesting, and effective to be used in Linear Algebra lectures
