Implementation of Team-Assited Individualization Instructional Strategies Supported by Geogebra Software to Improve Mathematical Problem Solving Ability Nasruddin, Nasruddin Mashuri, Sufri Jahring, Jahring Implementation of team assisted individualization instructional strategies supported by GeoGebra software to improve mathematical problem solving ability. Objectives: This quasi-experiment study aims to determine the effectiveness of Team Assisted Individualization (TAI) instructional strategies assisted by Geogebra graphical software to improve students’ mathematical problem solving abilities. Method: By cluster random sampling techniques, 66 students in grade VIII at SMPN 1 Wundulako were selected as sample. Data collection was carried out using pretest and posttest by applying test and non-test instrument. The data analysis was carried out with descriptive and inferential statistics. Findings: The Tukey test results showed that the significance value was 0.005 (α<0.05) with the average scores of the experimental and control classes 80.42 and 76.03. Conclusion: TAI strategy with graphical software is more effective in improving the mathematical problem solving ability than conventional learning. Keywords: Team assisted individualization, GeoGebra, mathematical problem solving ability DOI: http://dx.doi.org/10.23960/jpp.v9.i1.201903  FKIP Universitas Lampung 2019-04-24 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://jpp.fkip.unila.ac.id/index.php/jpp/article/view/575 Jurnal Pendidikan Progresif; Vol 9, No 1 (2019): Jurnal Pendidikan Progresif; 16-21 2550-1313 2087-9849 eng https://jpp.fkip.unila.ac.id/index.php/jpp/article/view/575/420 Copyright (c) 2019 Nasruddin Nasruddin, Sufri Mashuri, Jahring Jahring https://creativecommons.org/licenses/by-sa/4.0
