Abstract

The idea of integrating the Science, Technology, Engineering, and Mathematics in a problems brings a new paradigm in teaching and learning mathematics. The innovation to use STEM learning approach and its daily life’s applications, in the classroom allowed the students to enhance their mathematical communication skills. The research is aimed at determine the effectiveness of the STEM learning approach on mathematical communication ability. The research used Post-test Only Control Group Design. The population of the study is all of the third grade elementary school students of SD Laboratorium Undiksha and SD Mutiara Singaraja in academic year 2018/2019. The sample of the research was selected using total sampling technique. The member of the samples is 98 students. The data of student’s mathematical communication ability is obtained through a description test. The t-test with 5% significance level is used for analysing the data. The result of t-test is tcount = 7.278 and ttable = 1.997 so tcount > ttable, it means that student’s mathematical communication ability who followed the learning with learning STEM approach is higher than the student’s mathematical communication ability who followed thematic learning. Hence, it can be concluded that the STEM learning approach effectively improved student’s mathematical communication ability.
