There were differences in the ability of students' mathematical problem solving in post-test and delayed test, a positive result of students' mathematical disposition, there was an interaction mathematical problem solving and the level of student ability

Mengatasi Hambatan Berhitung Mencongak Menggunakan Strategi Mental dalam Materi Operasi Bilangan Bulat

This iams of this research is to overcome the obstacles arithmatic computation students use mental strategies in the material addition and subtractionof integers. The method used in this research is descriftive researh. The subjects consist of 9 student on grade VII SMP N 4 Sintang. The subjects were given three meeting treatment on mental strategies that Aggregation, Wholistic, Separation and separation left to right. Before being given the students mental strategies many obstacles arithmetic computation as, amounting to 77,8% of students still rely on stationery and using the standard way, by 43,2% students are taken more than 15 seconds to answer a question and 30,2 % of student answered incorrecly or not answered at all. After given a mental strategy aritmetic computation the students better than, no longer rely stationery and paper by 10% of studets take more than 15 seconds to answer question and only 6,7% of students incorrecly
