- Abstract
The reasoning and communication ability in learning mathematics junior high school still low. This indicated from the result of TIMMS and PISA. The aim of this research determine the improvement of student’s reasoning and communication ability of mathematics SMP 7 Padang whose approach contextual teaching learning aided students worksheet based on the 21st century. This study is a pre-experimental research. The study design used One Group Design and sample collection technique is purposive sampling. The research sample involving students of class VII in the school year 2017/2018 with class VII8 as an experimental class which have 30 persons. The ability of reasoning and communication mathematical is measured by test. The data were analyzed quantitatively by using independent sample t-test and normalization Gain Score. The results showed that the students average pretest score is 5.50 while the students average posttest score is 15.50. The results of gain scores obtained an average gain index of 0.54, means that there is an increase in student's mathematical reasoning and communication abilities after learning through of contextual teaching learning aided students worksheet based on the 21stcentury to the medium category.
