Abstract

This study aims to determine the use of the Students Team Assisted Division (STAD) type of cooperative learning model in a virtual classroom and its effect on learning outcomes of limit algebraic functions in class XI students of SMA Negeri 12 Ambon. This type of research is descriptive quantitative with experimental type Post Test Only Control Group Design. The population in this study were all students of class XI IPA SMA Negeri 12 Ambon. The research sample was 31 students in class XI IPA 1 and XI IPA 2. The results showed that descriptively the average percentage of the implementation of learning by teachers was 67%, and (2) the average percentage of student activity in online learning was 64% and ( 3) the difference in the average value of the experimental class and the control class is 6.42. Based on the inferential statistical test with independent t sample test calculations, the Sig value was obtained. (2-tailed) = 0.031 smaller than the value which means there is a significant difference between the learning outcomes of the experimental class and the control class. This difference shows that the use of STAD type cooperative learning in online learning has a higher contribution than conventional online learning

Abstract

Today's students must be able to optimize the dimensions of critical and creative reasoning abilities with the many digital-based learning resources that support this, especially to develop their abilities in Mathematics and Science subjects for students in class X-3 of SMP Negeri 1 Ambon, totalling 36 participants. This research aims to explore the application and challenges of critical and creative reasoning using qualitative methods with instruments like observation sheets. The research results show that most students are in good categories for the critical reasoning and creative dimensions. The critical reasoning dimension includes obtaining and processing information and ideas, analysing and evaluating reasoning, and reflecting on thought and thought processes that are in the good category. However, there is a need to improve the ability to make the right decisions. The creative dimension includes generating original ideas and producing original works and actions, which are also in the good category. However, there are challenges to increasing creative abilities to a higher level. This study also found that students' low basic abilities are the main obstacle in developing critical and creative reasoning dimensions of ability
