Abstract

This research aims to determine the influence of WhatsApp Group-based Blended Learning on students' critical thinking abilities. The study adopts a quasi-experimental design and is conducted at SMAN 8 Seluma. The sample consists of Class XII MIPA 1 as the experimental group receiving blended learning treatment, and Class XII MIPA 2 as the control group undergoing conventional learning. The Statistics Group Pretest-Posttest design is employed. Non-Probability Sampling is used for sample selection, and data analysis is performed using the t-test. The research findings reveal a significant difference in students' critical thinking abilities between the experimental and control groups. The average critical thinking ability score for the experimental group is 49.55, while for the control group, it is 46.43. The t-test results indicate a significance level of Sig. (2-tailed) = 0.000 < 0.05, and Tcount (calculated t-value) = 5.668 > Ttable (critical t-value) = 2.022 (sig: 5.668 > 2.022). Therefore, H1 is accepted, and H0 is rejected, leading to the conclusion that WhatsApp Group-based Blended Learning has a significant influence on students' critical thinking abilities.

Abstract

This study aims to determine the effect of augmented reality-based laboratory guidelines on students' science literacy and interest in learning. Two classes were involved as the experimental class and the control class with different treatments. The experimental class applied Augmented Reality-based laboratory guidelines, while the control class did not. The research sample was class X IPA 2 as the experimental class and class X IPA 3 as the control class. The instruments used were essay questions to measure literacy skills and questionnaires to measure learning interest. The results showed that there was a significant effect of Augmented Reality-based practicum guides on students' science literacy skills, with a sig value < alpha value, namely 0.000 < 0.05, or tcount > ttable, namely 4.161 > 2.010. In addition, there was also a significant effect on students' interest in learning, with a sig value < alpha value, namely 0.00 < 0.05 or tcount > ttable, namely 4.790 > 2.010.
