Abstract

Mathematics becomes more meaningful when it is relevant to real life and students are more engaged in mathematics learning when it relates to them. Contextual teaching and learning (CTL) is a teaching concept that connects knowledge to real-world situations. The present study aims to investigate the effect of CTL on students’ conceptual understanding of geometry. This experimental study employed a pre-test-post-test control group design. The samples are all eighth-grade students in Junior High School 4, Sakti Pidie, A census sampling technique was used in this study since all members of the population served as samples. The experimental class and the control class were randomly selected from the two available classes. The experimental class was taught geometry using CTL while the control class was taught conventionally. Data were collected from pre-test and post-test that were declared valid. Data analysis was performed using the Kolmogorov-Smirnov test for normality test, the Levene test for homogeneity test, and t-test for the hypothesis testing. The results revealed that students taught using CTL have better conceptual understanding of geometry compared to those who were taught conventionally. It implies that the implementation of contextual teaching and learning (CTL) on geometry learning is effective to promote students’ learning.Keywords: Contextual teaching and learning, conceptual understanding, geometry learning.

Abstract

This study aims to improve the critical thinking skills of students of SMA Negeri 1 Sigli through the application of the Project Based Learning learning model using the maple calculator application. The population in this study were all 210 students of grade XI of SMA Negeri 1 Sigli. The population in this study was more than 100, so a sample of 2 (two) classes was taken, namely the experimental class and the control class, totaling 60 students. The research method used was quasi-experimental. The experimental class used the Project Based Learning model using the maple calculator application, while the control class was given learning with conventional methods. Data collection was carried out with a final test, and data processing used the t-test. The results of data analysis showed that the average value of the experimental class was higher, namely 87.40 and the control class 79.27. The results of hypothesis testing obtained t-count t-table, namely 3,541 2,002. Thus, the application of the Project-Based Learning learning model using the maple calculator application can improve the critical thinking skills of students of SMA Negeri 1 Sigli.
