PENGARUH DISPOSISI MATEMATIKA TERHADAP HASIL BELAJAR SISWA SMA DALAM PEMBELAJARAN DI INSTAGRAM

AbstractMathematical disposition is one of the most studied variables in offline learning. When online learning is carried out, this variable is often forgotten because of the difficulty of capturing this phenomenon in learning. This variable is needed to improve the quality of mathematics learning in class and student learning outcomes. This study aims to find the effect of students' mathematical disposition on learning outcomes in learning with the Instagram (IG) platform. The research was conducted in class XI IPA SMAN 15 Bandar Lampung using the causal method and the research population was 282 people. The variables in this study were students' mathematical disposition (X) and students' mathematics learning outcomes (Y). The data were obtained through a questionnaire instrument for students' mathematical dispositions and a mathematical test instrument. Hypothesis testing is done by a simple linear regression test using = 0.05. The regression equation is obtained = 35.811 + 0.026X with = 0.09. The significance value of mathematical disposition is 0.048 (i ) so it can be concluded that there is an influence of mathematical disposition on the understanding of mathematical concepts of class XI students of SMAN 15 Bandar Lampung.Keywords: instagram; learning outcome; mathematical disposition AbstrakDisposisi matematika merupakan salah satu variabel yang banyak diteliti dalam pembelajaran offline.
