The purpose of this study was to describe the ability of verbal representation, image representation, and representation of symbols, as well as an understanding of junior high school students on statistical material. This study uses descriptive research methods. The conclusions obtained from this study are the indicators of verbal representation capabilities and indicators of the capabilities of the representation of the image or visual three subjects studied have been quite mastered. In indicators, the ability of the symbolic representation is only two subjects that have mastered, while the other subjects do not understand the representation of the symbol. In an understanding of statistical material, the average of the three subjects studied has sufficiently mastered statistical material.

This research was conducted in class X mathematics learning at one of the public high schools in Salatiga on Trigonometry material. This quasi-experimental study used a randomized control group pretest-posttest design, with instruments in the form of problem-solving ability tests and observation sheets. The data analysis used was the covariance test at the significant level α = 5% with the initial ability as a covariate variable. The results of hypothesis testing with covariance analysis concluded that by controlling students' initial abilities it was found that there were significant differences in mathematical problem-solving abilities between the application of the two models. Students who carry out the Problem Posing learning model significantly have better mathematical problem-solving abilities than students who carry out the Problem-Solving learning model.
