Learning math using rote memorization, making it difficult students understand the basic concepts of multiplication and division. Students also thought that mathematics is a difficult subject and tedious, because teachers rarely use the model of learning and use of media only using the environment around students. This study aims to determine whether there is any difference in learning outcomes of students who use and do not use media-assisted learning model TGT grain basket. This study uses a quantitative approach with experimental methods and research design quasi experiment. This research sample that is grade II totaling 50 students and consists of two classes. The results of this study were tested using paired samples t test and obtained t of 5.057 while t table (sig. 0.05 and df = 23) of 2.069 which indicates thitung greater than ttable namely: 5.057> 2.069 which means that H0 rejected and Ha accepted. So it can be concluded that there is a significant difference between the results of student learning to use and not use the media-assisted learning model TGT grain basket.

The focus of this research was to develop a syntax model forMathematics learning using open-ended problem solving that can develop students' creativity. The emphasis on creativity development was done since the curriculum and the experts also emphasize it. This can be understood since someone with high creativity can quickly make innovations or new breakthroughs. The design research used in this study followed Plomp's design research (2007), which consisted of: (1) preliminary research phase; (2) prototyping phase; and (3) assessment phase. The syntax model produced in this research has five phases, namely: (1) introduction; (2) concept tracking; (3) open-ended problem presentation; (4) presentation of work; and (5) closing. Key Words:Syntax Model, Open-Ended Problem Solving, Creativity A. BackgroundIt is important for teachers at schools to emphasize the development of creativity. This can be seen from the standards of the 2013 Curriculum process which contains activity-based learning for elementary and secondary schools and gives enough space for the development of creativity. This is also in line with the wishes of Indonesia's Deputy Minister of Education, who believes that learning should support the students' creativity development. More specifically, Wardhani (2011) recommends that Mathematics learning needs to be triggered by Mathematics problems that require reasoning, trial, nontrivial solution, which triggers the students' curiosity on related mathematical ideas. The emphasis on this kind of learning can be understood since someone with high creativity can quickly create innovations or new breakthroughs.

Abstract. This study purposedto develop module of numbers learning by CTL approach. Through CTL strategies, students were expected to learn through 'experience', but not 'memorize'. This module included activities to create a meaningful relationship, presenting a problem in the form of open-ended, problem possing assembling, collaborating, presenting individually services through checking the understanding, and self-assessment. The development model used in this research were divided into three phases: (1) the initial investigation phase (2) the prototype phase, and (3) the assessment phase. The research instrument composed in this study consisted of; (1) questionnaire responses of experts and practitioners, (2) student questionnaire, (3) sheets and questionnaires observation, (4) the test sheet. This development product had fulfilled valid criteria by the achievement of the module validation was 3.31 (high criteria), Observation Students'Activities validation was 3.52 (high criteria), Students' Questionnaire Response validation was 3.27 (high criteria), and Test Learning Result validation was 3.44 (high criteria). Based on the validation results, it could be concluded that the module and instrument which were developed was valid.

AbstrakPermasalahan yang sering dialami siswa sekolah dasar yaitu kesulitan dalam melakukan operasi penjumlahan dan pengurangan yang melibatkan bilangan bulat negatif. Penggunaan buku paket dari pemerintah dan LKS hanya memuat soal-soal rutin yang hanya mengembangkan pengetahuan dan kecepatan siswa dalam berhitung tetapi belum mengembangkan keterampilan berfikir kritis dan kreatif mereka. Dampak dari penggunaan bahan ajar tersebut siswa kesulitan dalam memahami materi bilangan bulat. Penelitian ini bertujuan untuk mendiskripsikan pembelajaran dengan menggunakan modul pembelajaran penjumlahan dan pengurangan bilangan bulat dengan pendekatan CTL yang dapat meningkatkan pemahaman konsep siswa kelas IV Sekolah Dasar. Metode yang digunakan dalam penelitian ini yaitu penelitian tindakan kelas dengan subjek penelitian yaitu 20 siswa kelas IVB SDN Kotalama 1 Malang. Produk penelitian ini berupa rancangan pembelajaran dengan menggunakan modul pembelajaran penjumlahan dan pengurangan bilangan bulat dengan pendekatan CTL. Hasil penelitian menunjukkan penggunaan modul pembelajaran penjumlahan dan pengurangan bilangan bulat dengan pendekatan CTL dapat meningkatkan pemahaman konsep siswa kelas IV SDN Kotalama 1 Malang dengan presentase keberhasilan yang telah ditetapkan peneliti tercapai pada siklus II yaitu persentase ratarata skor hasil tes akhir meningkat dari 70% menjadi 85%, hal ini menunjukkan bahwa pemahaman konsep siswa semakin baik. Kata Kunci: Modul, CTL, bilangan bulat, pemahaman konsep AbstractProblems that are often experienced by elementary school students are difficulties in doing addition and subtraction operations involving negative integers. The use of government textbooks and worksheets contain only routine matters which only develop their knowledge and speed of students in math but have yet to develop critical thinking skills and their creative. The impact of the use of the instructional materials students difficulties in understanding the material integers. This study aimed to describe the learning by using learning modules addition and subtraction of integers with CTL approach that may improve understanding of the concept of Elementary School fourth grade students. The method used in this research is a classroom action research with research subjects are 20 of IV grade SDN Kotalama 1 Malang. The products of this research is the design of learning by using learning modules addition and subtraction of integers with CTL approach. The results showed the use of learning modules addition and subtraction of integers with CTL approach can improve understanding of the concept of fourth grade students of SDN Kotalama 1 Malang with a percentage of success that has been established researchers reached the second cycle is the average percentage score of final test results increased from 70% to 85%, this indicates that the better students' understanding of the concept..
