Increasing Student’s Learning Activity on Trigonometry Material through a Contextual-Based Group Investigation Learning Model

Mathematics is the least preferred and most difficult subject for most students, especially when it comes to trigonometry. This is reflected in student learning outcomes and students’ daily test results, which are always lower than other majors, and a maximum of 40% of students graduate. One of the causes is a lack of interest in teaching and learning in the classroom. Therefore, it is necessary to carry out learning activities with a learning model that is expected to make learning conditions or environments more comfortable for students. The process consists of two cycles using the group investigation learning model. At the end of the study, the following results were obtained: In Cycle I, the average student achievement was 31,6 percent; in Cycle II, it rose to 70,3 percent. Mastery of subjects also increased, which increased the average student achievement from 63,5% in cycle I to 64,9% in cycle II.

Development of Web-Integrated Investigation Worksheet about Protists

This study aims to produce a web-integrated investigation worksheet about protists that is valid, practical, and effective by following the McKenney & Reeves development model. The validity of the worksheet was obtained by filling out a validation questionnaire by teaching material experts and microbiology experts.

The conclusion of this research is that the application of the Group Investigation (GI) learning model with Mind Mapping is effective in increasing students' motivation and learning outcomes in Animalia material compared to conventional models.

Ma’kombongan Based Group Investigation Learning Model In Analyzing Controversial Cases Related To The Teaching Of Civic Education

Civic Education learning is considered boring by some students, mainly because the subject matter and delivery are presented in a one-way format. Civic Education in higher education should transition to a problem-based learning approach, making it more contextual and dynamic. Civic Education in college shouldn't be monotonous memorization; instead, it should focus on enhancing analytical and applicative thinking skills and the ability to provide input on existing phenomena or issues. Therefore, a learning model that encourages active student participation, such as the problem-based , is needed. This model aims to explore the depth of controversial issues discussed by students. The research results reveal the controversial issues and how the ma'kombongan-based group investigation process can improve students' analytical skills and reasoning abilities.
