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.

Abstract

The mathematical connection ability of junior high school students in algebra material is still low due to the dominance of learning procedures and minimal use of digital technology. The novelty of this study lies in the integration of the Project Based Learning learning model with the Cymath application to strengthen students' mathematical connections. This study aims to analyze the effect of the application of the Project Based Learning learning model assisted by Cymath on the mathematical connection ability of seventh grade students of SMP Negeri 1 Delima. The study used a quasi-experimental method with a pretest-posttest control group design on 60 students divided into experimental and control classes. Data were collected through a mathematical connection ability test and analyzed using a t-test. The results showed that the average mathematical connection ability of the experimental class (88.73) was higher than the control class (78.60), with a calculated t-value > t-table (3.976 > 2.002). These findings indicate that Cymath-assisted PjBL can improve students' mathematical connection ability. Theoretically, this research supports project-based constructivist learning and digital technology, while practically it provides an alternative innovative algebra learning for junior high school teachers.
