Developing a Mathematic Learning Device with PMRI Approach Oriented on Mathematical Representation Ability
Abstract
This development research was aimed to produce the lesson plan (RPP) and the worksheet (LKS) are valid, practical , and effective. RPP was developed contain PMRI syntax, ie understanding the contextual problems, describing the contextual problems, solving the contextual problems, comparing and discussing the answers, and concluding. LKS was developed facilitate the mathematical representation ability, ie expressing the verbal to symbol, the symbol to the visual, and the verbal to visual. The validaty of product can be seen from the results of experts validation which demonstrates that the product is valid. The practicality of product can be seen from the result of the teacher practicality assessment sheet which shows that the product is in a practical category, the result of the students assessment sheet shows that the product is in a practical categories, learning implementation observation shows that the minimum implementation percentage is 88.89% and maximum is 100%. The effectiveness of the product can be seen from the results of mathematical representation ability test. The result of mathematical representation test shows that percentage of students who reach the KKM is 76.67% with a mean value of 77.67%. Overall the results of this study show that the developed learning tools are feasibel to use.
