Abstract. This study aims to: improve the independence of students in learning mathematics through Cooperative Learning methods and make a match strategy using authentic assessment. This type of research is the Classroom Action Research (CAR) collaborative. The subjects are students in grade VIII SMPN I GumukmasÂ School Year 2011/2012, amounting to 33 students as subjects who received the action. Implementation of the action is the subject of research. Subjects who supported the implementation of the math are teachers and principals. Data collection methods are used the method of observation, test methods, reviews and documentation methods. Data analysis technique is implemented in a descriptive qualitative. It is found on the average the students activity improve 66,7% at siklus I become 78,8% at siklus II, and the teacher activity improve 4,66%. The classical thoroughness improve 33,34%. So the conclusion of this research is the application of the make a match approach can improve theostudent achievmentoinklearningomathematics.

Abstract. Numbered Heads Together is a cooperative learning strategy that holds each student accountable for learning the material. The advantage of NHT (Numbered Heads Together) is that it has numbering system. Type of research was Classroom Action Research (PTK). The research subjects of was grade VII A students of SMP Negeri 1 Kedungjajang and material the chosen was one variabel linear inequality. The data collection methods used in this research were observation, interview, test, and documentation. In the first cycle, the completeness of the students learning classical outcomes was 73,33% . And the second cycle, the completeness of the students learning classical outcomes was 86,67%. The first cycle to the second cycle was 13,34%. Â Key Words : NHT, Cooperative Learning. One Variabel Linear Inequality, Students learning.
Abstract.The objectives of this action research are to know how the implementation of learning Quick on the Draw, the students activities in learning process, and the studentâs outcomes after using the implementationof learning Quick on the Draw of Social Arithmetic at VII grade material. This implementation was conducted in two cycles, and each cycle was ending with a test. This research using Hopkins scheme model that consist of 4 phases include planning, action, observation and reflection. The object of this research was students of class VII F of SMP Negeri 10 Jember. The data collection methods of this research were observation, interview, test and documentation. In Cycle I, the research shows that studentâs activities were 85,55% and the students learning outcome were 82,85%. In Cycle II the studentâs activities were 91,42% and the students learning outcome were 97,14%. It conclude that this research can improve the studentâs learning outcome.

Abstract. The purposes of ARIAS (Assurance, Relevance, Interest, Assesment, Satisfaction) learning model are improving motivation, achievement and result of student learning. Guided discovery method has characteristics to improve the studentâs abstract minds. The research aims to know process and result of development of mathematics learning materials based on ARIAS learning model with guided discovery method at sub topic of circle at grade eight of Junior High School. Learning materials development model refers to 4D Thiagarajan models. The products of this research are lesson plan, student book, worksheet, and evaluation test. Based on validation process and tryout the learning materials can be concluded that the learning materials had been appropriate with validate, practice, and effective criteria.

Abstract.The aimof this research is to develop an audio based math media.It will help blind stunentd to understand thecircumferenceandtriangle area concepts. The methodis obtained from modifyng Four D modeland data collecting proccessin this research usequestionnaires andobservation. The validation results done by computerexpert, education expert and math teacherof SMPLBclass VII-A shows that 87.91% of the criteria have been fullfiled the validityand no revision required. The next stepis implementation test forblind studentsof class VII. The media test results shows that 92.85% have been fulfilledthevalidity. It means that the media has a very valid category and no revision required. The development result ofaudio based math media is an executable software. The product of this research are 6 units audio based math media and the manual book.

Abstract. Developing CTL approach of learning materials focused on learning community need to developt this time, due to the fact that students are not only abble to understand realisticly but also they should be able to work in a group. The purpose of the research is to discrible the process and result of develompent of CTL mathematics learning material focused on learning community for triangle topic seventh grade student of Junior High School. The development model refers to Plomp model, namely investigation, design, realisation, test, evaluation, revition, and implementation. The products of this research are lesson plan, worksheet, and evaluation test. Based on validation process and learning materials tryout, it can be concluded that the learning materials have fulfilled approprite with validaty, practicy, and effectivy criteria.
