Abstract: The purpose of this research is to analyze the effect of IDEAL problem solving with Numbered Head Together (NHT) cooperative learning towards the students’ ability of mathematical critical thinking. The research is conducted in SMP N 18 South Tangerang, in academic year 2014/2015. The method used in this research is quasi-experimental method and the design is Control Group Post-Test Only Design. This research involved 72 students as samples. The data collection was done after a mathematical critical thinking test was given to students. The result shows that the students who are taught by using IDEAL problem solving with NHT cooperative learning have a higher mathematical critical thinking ability than those who are not (ttest =2,38 > ttable =1,67). It can be seen from the average of the mathematical critical thinking test result, those who are taught using IDEAL problem solving with NHT cooperative learning achieved an average result of 63,32 and those who are taught using conventional method achieved 55,79. According to the result value of each indicator, the class using IDEAL problem solving with NHT cooperative learning achieved 79,00 in interpreting indicator, 62,13 in analyzing indicator, and 53,00 in evaluating indicator. While the class using conventional method, it 77,63 in interpreting indicator, 51,13 on analyzing indicator, and 42,38 on evaluating indicator. The conclusion of this study is teaching mathematic especially on the subject sets that use IDEAL problem solving with Numbered Head Together cooperative learning significantly effect students’ ability of mathematical critical thinking.
