Numerical Ability Analysis: The Impact of the Two Stay-Two Stray Learning Model on the Sequence and Series Topic in Islamic Boarding School

Abstract

Abstract Numerical ability is very important to possess by students in learning mathematics. Increased numerical ability impacts learning outcomes. The purpose of this study was to determine the impact of the Two Stay-Two Stray learning model on the numerical ability of students on the sequence and series topics. The research method used was a quasi-experimental method with a post-test-only control design research design. The assessment instrument used the problem description. Based on the analysis of the post-test score by using a t-test of two uncorrelated samples obtained t observed = 2.955>t critical = 2.002 (α = 0.05) with an average post-test score of 81.6 in the experimental class and 76 in the control class. A significant result of numerical ability between the control class and the experimental class was found. It can be concluded that the Two-Stay Two-Stray model produced a greater post-test mean score than the conventional model.
