Abstract

Problem solving capability is one of the main focus central In mathematical learning. The results of student research are able to solve problems that are complicated and able to formulate, and communicate their findings. This means that the percentage of students who are able to solve the problem with the correct strategy and procedure is still slightly compared to the percentage of students who solve the problem using the formula. One of the efforts to improve the learning process is to choose the right and innovative learning model in mathematics learning, with the steps to give practice about the problem-math problems in the statistics material found in the UN can help in solving problems when the UN progresses. This study aims to test the problem solving skills of grade XII students SMA in learning. Subjects were chosen taking into consideration the teacher's explanation of students ' ability to solve problems.
The group's students are able to understand the problem well, able to plan
settlement appropriately, able to implement the plan of completion according to what Are planned, and are able to look back at results and processes. Group students are less able to understand the problem, but are able to plan Properly, able to implement settlement plans in accordance with the Planned, and able to look back at the results and process. Lower group students are less able to understand the problem, but can To plan solutions appropriately, able to implement The completion of what is planned, but underprivileged to Look back at results and processes.
