Daftar Isi:
- This study is descriptive research that aims to investigate the students’ ability in comprehending the mathematical concept of the powers of numbers of integer material using PMRI and LSLC approaches. The subject of this study is the 7th graders (VII.C) of SMP Srijaya Negara which numbered 30 students. There are four stages of LSLC in this study. First is design stage that is adjusted to the principles and characteristics of PMRI. The second is do (implementation) stage. The third is see (reflect) stage. The last is redesign stage. The learning process is adjusted to the principles and characteristics of PMRI and learning community. The data collection technique used in this study is written test consisting of 2 essay test items, observation and interview needed to obtain the supporting data. Based on the results of the study, it is found that the overview of the students’ ability in comprehending the mathematical concept of the powers of numbers of integer using PMRI and LSLC approaches with the following details: in question number 1, the indicator that often appears is the indicator that that apply concept or algorithms in problem solving. Then, for the question number 2, the indicators that often appear are the indicator of the ability to use, utilize, and choose certain procedures and indicator to apply concept t or algorithms in solving problem. Then, in question number 1 and 2, the indicator that most rarely appear is indicator of restating the concept.
