PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE STUDENT TEAMS ACHIEVEMENT DIVISIONS (STAD) TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA KELAS X SEMESTER GANJIL DI UPT SMK NEGERI 9 BANDAR LAMPUNG TAHUN PELAJARAN 2022/2023

Ability, problem solving, STADAbstract
The purpose of the study was to determine the effect of the Student Teams Achievement Division (STAD) type cooperative learning model on solving math problems for class X SIJA students at SMK Negeri 9 Bandar Lampung. Analysis of research data using parametric statistics. The research population of class X students of SMK Negeri 9 Bandar Lampung, the sample was taken 2 classes, namely X SIJA 1 as the experimental class and X SIJA 2 as the control class which were taken using cluster random sampling technique. The ability to solve mathematical problems as measured by an essay test with 5 questions. Hypothesis testing using t-test, with t_hit = 5.60. At a significant level of 5%, t_daf=1.67 means t_hit>t_daf which is 5.60>1.67. It was concluded "There is an effect of applying the Student Teams Achievement Division (STAD) type cooperative learning model on math problem solving for X grade students of SIJA SMK Negeri 9 Bandar Lampung in the academic year 2022/2023". This situation is seen from the average score of the experimental class students which is 77.56, which is greater than the control class which gets an average score of 63.18
