Desain Bahan Ajar Penjumlahan Pecahan Berbasispendidikan Matematika Realistik Indonesia (Pmri) Untuk Siswa Kelas IV Sekolah Dasar Negeri 23 Indralaya

This research purposes to result teaching material of fractional summation on Indonesia Realistic Mathematic Education (PMRI) basis for class IV of SD N 23 Indralaya and find out dtudent's in enumerating fractional trough activity from informal to formal. The research subject of class IV SD N 23 Indralaya. Researcher used the methods: Design research ( Gravemaije, 2009) designed in 3 stages, i.e. Front – end analysis and expert review, teaching expriment and reflection, and assessment and evaluation stage. Based on front- end analysis, teaching material design on PMRI basis in the from of student book and teacher',s. Stage was teaching experiment carried out in class IV and observerped by 4 (four) observers, 3 obsevers observed studens aktivity and 1 (one) obsever which was the researcher erself observer the students and teacher activities, the result (after analyzed) was indicator 1 with the best category, indicator number 2, 3,4,5, 6, 7, and 8 student activity were seen well category, while in indecator numser 9 with poor criteria. Menwhile in the third stage was assessment or evaluatin was carried out to refer the students learning result achievement either daily evaluation or assignments. For daily evaluation result was 97,96% achievement in summsting the efrction with simelar quotation, 85,71% different quotation 65,21% student,s achiefement in summating mixed fraction and 83,67% student,s achievement in summating defferent quotation fraction with mixed mix praction.The student's assignment result for the first student who reached ≥ KKM was 33 students (67,30%), second assignment achievement was 38 students (77,66%), the third assignment achievement was 40 students (81,63%), and the fourth assignment reached 41 students (83,67%) which generally the assignment result was increasing

Building Counting by Traditional Game: Mathematics Program for Young Children

In line with design research, the use of Bermain Satu Rumah (BSR) as traditional game to support children\u27s counting classroom wherein students are encouraged to construct mathematical understanding. Number in traditional games is an interesting aspect that is helpful for children to encounter numerous situations that bring them into contact with sounds, symbols and meanings that relate to numbers. Bermain satu rumah as starting activity would be media to enhance student\u27s sense of number as well as to be used as learning material. By developing model-of problem of bermain satu rumah as traditional context, resultative counting is counting a number of things with the aim of determining how many are there (the result) that can be showed by using addition and multiplication concepts. Student\u27s thinking on their level exhibited us their successful conservation when they were in the last grade. The progress of understanding by game, especially bermain satu rumah, is concrete effort to support number learning in primary school. Using game in learning process, for instance, mathematics learning for primary school can be a mathematics program for young children
