Abstract

This study aims to determine the effect of giving independent assignments on student learning outcomes in the Histology course. The method used was a quasi-experimental design with a pretest-posttest control group design. The study subjects consisted of two classes: a treatment class given independent assignments and a control class without similar treatment. Data were collected through pretests and posttests, then analyzed using paired t-tests and homogeneity of variance tests. The results showed a significant difference between pretest and posttest scores in the treatment class (p = 0.000 < 0.05), while the control class showed no significant difference (p = 0.348 > 0.05). These findings indicate that giving independent assignments can significantly improve student learning outcomes. Thus, independent assignments are effectively implemented as a learning strategy in the Histology course to train students' independence, responsibility, and critical thinking skills.

Abstract

This study aims to determine the effect of the application of the Team Games Tournament (TGT) model on biodiversity materials based on QuizWhizzer game media on the motivation and learning outcomes of grade VII students of SMP Negeri 7 Samarinda. The research method used was a quasi-experimental with a pretest-posttest control group design. The research subjects consisted of 25 students in grades VII-D as an experimental class using the QuizWhizzer-based TGT model, and 25 students in class VII-F as a control class using the discovery learning model. The results of the study showed that there was a significant influence of the application of the QuizWhizzer-based TGT model on student motivation and learning outcomes. Based on the results of the t-test, a significance value (2-tailed) of 0.001 < 0.05 was obtained which showed a significant influence on learning outcomes. The results of the N-Gain test showed an increase in learning outcomes in the medium category, with an average increase in the experimental class of 0.43, while the control class was 0.35. In addition, the results of the Mann-Whitney test on learning motivation showed a p-value of 0.000 < 0.05 which means that there is a significant difference between the two classes. Thus, it can be concluded that the use of the Team Games Tournament (TGT) model based on QuizWhizzer media has a significant effect on increasing student motivation and learning outcomes. This model has also been proven to increase students' interest in the learning process through fun game elements.
