THE EFFECT OF LEARNING MODELS MISSOURI MATHEMATICS PROJECT WITH TWO STAY TWO STRAY METHODS FOR MATHEMATICAL PROBLEM SOLVING ABILITY OF STUDENT IN 7 th GRADE SMP N 1 TAWANGMANGU

Abstract

Abstract
This study aims to determine the effect of learning models of Missouri Mathematics  Project with Two Stay Two Stray
methods for mathematical problem solving ability of grade VII students of SMP N 1 Tawangmangu. The method in this
study is a quasi experimental research design with pre-test post-test design group. The population in this study were all
students  of  grade  VII  of  State  Junior  high  School  1  Tawangmangu.  The  sample  in  this  research  is  grade  VII  F  had
treatment with Missouri Mathematics Project learning models of Two Stay Two Stray method as the experimental class
and  grade  VII  G  as  the  control  class  who  receive  conventional  learning  treatment.  This  instrument  were  tests  and
observation sheets. The hypothesis test method used was one sample test and t-test independent sample. Based on the
results of data analysis, the value of t
count
= 7,171 > t(0.05:31)
=2,0395 with a significance level of 5% thus Ho rejected
which means that the learning model of Missouri Mathematics Project with Two Stay Two Stray method was effective in
terms of students’ mathematical problem solving ability. The  results of data analysis obtained the value of t
count
= 6,476
>t(0.05:62)
=1,998971 thus Ho was rejected. This means that the learning model of Missouri Mathematics Project with Two
Stay  Two  Stray  method  affected  the  ability  of  students'  mathematical  problem  solving.
