Application of Problem Based Learning Model Assisted by Cabri Software to Improve Problem Solving Ability of Mathematics Students

This study aims to determine how the increase in mathematical problem solving ability (KPMM) Nurul Hikmah
junior high school (MTs) students through the application of learning models aided Problem Based Learning (PBL) Software Cabri and evaluate the response of junior high school students Nurul Hikmah field against learning PBL assisted Software Cabri. The subjects were students of class VIII MTs Nurul Hikmah Tinjowan field totaling 24 people consisting of 14 men and 11 women. The results showed that there was an increase in mathematical problem solving ability of students are evident from the results of the pretest and posttest. On the pretest results showed that students who scored more than 70 number
only 4 people or by 16.7% and students who scored less 70 some 20 people or 83.3%. And the average value of students in the pretest was 55.7. Then, after the learning process using the model-assisted learning PBL Software Cabri results indicate an increase in the students who scored more than 70 number only
14 people or by 58.3% and students who scored less 70 some 10 people or 41.7 %. The average value of students in the pretest was 70.2. Comparison hail pretest to posttest are students who experienced an increase amounting to 19 people or 79.2%, of students who experienced a decrease amounted to 4 people, or
16.6% and continuing students that do not decrease or increase amounted to 1 or 4.2%. And based on observations conducted by researchers of the students. The response shown by students very well, the students feel interested when teachers use learning model PBL that were active learning because teachers give LAS containing the real problems is done in groups and students are very interested when the teacher explains the use of the Cabri
Software in material cube.
