![]() The instruments used in this research are the score of the test, observation, interview and photo documentation guidelines. Technique of data collection that used was essay, observation, interview, and documentation. ![]() Each appointment has 4 steps which are planning, performing, observating and reflecting. This research was conducted in 2 cycles with 2 appointments every cycle. Research variable is mathematics education approaching realistic and mathematics studying result student on material determines cuboid and cube net. This classroom action research was conducted with students in class IV SD I prambatan Lor in the academic year 2013/2014 with total 27 students, consist of 13 sons and 14 daughters. This research hypothesis is Mathematics education approaching Realistic Indonesian (PMRI) can increasing mathematic learning achievement student in class IV SD I Prambatan Lor on material determines cuboid and cube net. Realistic Mathematics education Indonesian (PMRI) is a special learning approaching for mathematics subject that emphasize mathematics as activity of student and involve environmentally and about problem realistic on daily life to be made as media or student studying source. Cuboid is built spatial one be drawn the line six flank get to square form and length square. Cube is a one spatial build that drew the line by six squares that coextensive. ![]() Net is a sliced spatial build on its flank part, and then is fallen down, so forms monotonic build. Mathematic learning achievement be changed one be gotten by student of mathematics learning that utilized reasoning ability and also student logic. The purposes from this research are: (1) describing PMRI approaching implement to increase mathematics studying result material determines log net and cube on students in class IV SD 1 Prambatan Lor in the academic year 2013/2014 (2) describing PMRI approaching implement to increase student studying activity in class IV SD 1 Prambatan Lor in the academic year 2013/2014 on material determining cuboid and cube net (3) describing PMRI approaching implement to increase teacher skill in bring off mathematics learning activity on material determines cuboid and cube net. There are some cause, which is: (1) learning gets conventional character (was seen context and modeling purpose) and (2) don't mark sense construction result exploit student, interactivity and relevance among mathematics concept. ![]() S tudents who actively provide d ideas in the first cycle group by 47.05% and increased to 88.23%.The backgrounds of this research its low of mathematic students learning in class IV SD 1 Prambatan Lor Kaliwungu Kudus. Students who were serious about doing the first cycle group assignments, 64.70%, increased to 88.23%. Students actively answer ed the first cycle questions 29.41%, to 64.70%. Students we re actively cooperating in the first cycle group, 52.94%, to 88.23%. The learning process from cycle I to cycle II wa s that students actively pa id attention to the explanation of the teacher in the first cycle of 70.58% to 94.11%. The results showed that the observations of the first cycle experienced an increase, with an average of 3.38 were categorized as sufficient, and in the second cycle, being four were categorized as good. The research method in this study wa s a qualitative method of classroom action research (CAR). The purpose of this study was to describe the improvement of student learning outcomes in IV grade of the State Elementary School 15 Delta Pawan (SDN 15 Delta Pawan) on reading comprehension material with group work methods. ![]()
