Abstract
The mathematical connection ability is very important for students. The mathematical connection ability includes (1) connection between mathematical topics, (2) connection with other disciplines, (3) relationships in everyday life. The aimed of this research was to describe the effect of problem-based learning on mathematical connection ability of the 8th class students (age 13-14). This research was quasi-experiment with one group pretest-posttest design. The research samples consisted of one class taken randomly from 4 classes in the population. The data collected by using mathematical connection ability achievement test that has been declared valid by the expert team. The data analysis used one sample t-test. The criterions of effective are: 1) posttest score is higher than pretest score and 2) the proportion of student that pass the mathematical connection criterion is more than 75%. Based on the result of one sample t-test, the significance value is 0,000, it can be said that the problem-based learning approach is effective in terms of students mathematical connection ability. The effectiveness of mathematics learning with problem-based learning approach reach 87,55%. It can be concluded that the problem-based learning is effective on mathematical connection ability.
