Pengaruh Penerapan Pendekatan Contextual Teaching and Learning (CTL) Terhadap Kemampuan Pemecahan Masalah Matematis Siswa

Abstract

The problem in this study is the low ability of students' mathematical problem
solving in learning mathematics. The purpose of this study was to determine the effect
of applying the contextual teaching and learning approach to the mathematical
problem solving abilities of Grade VIII students in odd semesters of SMP Negeri 34
Bandar Lampung in the 2022/2023 academic year. This study used an experimental
method with the population in this study, namely all students of class VIII Odd Semester
SMP Negeri 34 Bandar Lampung, while two classes were taken as samples, namely
class VIII B which used a contextual teaching and learning approach, and class VIII A
which used a conventional approach. Samples were taken using the Cluster Random
Sampling technique. To find out students' mathematical problem solving abilities, a test
was carried out in the form of an essay of five questions which had previously been
tested for validity and reliability. Hypothesis testing in this study uses the t-hit formula.
From the results of testing the hypothesis using the t-hit statistical formula, the value
of t hit = 2.60 is obtained. From the t distribution table at a significant level of 5% it is
known that t daf = 1.67, then t hit > t daf , which means that the average mathematical
problem solving ability of students using the contextual teaching and learning
approach is higher than the average mathematical problem solving ability of students
using the conventional.
