Abstract

The low student learning results may be observed in the value decided by the teacher, which is less than the KKM's average value of 75. The purpose of this study is to determine the impact of the mnemonic learning model on student biology learning outcomes in class XI MIPA SMA Negeri 4 Manado during the academic year 2021/2022. This study used a quasi-experimental design. This study's sample included two classes: class XI MIPA 1 as an experimental class with 20 students and class X1 MIPA 2 as a control class with 20 students. The results showed that the average pretest and post-test learning outcomes obtained by students in class XI MIPA 1 (experiment) with the application of the pretest mnemonic learning model were 34.75 and 76.75, respectively, while the pretest and post-test learning outcomes obtained by students in class XI IPA 2 (control) with only conventional learning were 31.25 and 71.25, respectively. The value of tcount> ttable was derived by hypothesis testing the pretest and post-test data in the experimental and control classes at a significant threshold of 0.05. The table value is 2.024, whereas the count value is 2.681. H0 is rejected based on the hypothesis testing criterion, but H1 is approved. This suggests that H0 has no effect, however H1 has an affect on student learning outcomes in Biology class XI at SMA Negeri 4 Manado.

Abstract

Studying biology serves as a means to enhance understanding, abilities, perspectives, principles, and ecological accountability. Biology is the scientific discipline that seeks to understand the natural world. Learning biology entails more than simply acquiring factual knowledge, concepts, or principles; it is also an exploratory endeavor. This research aims to discuss problem-based learning (PBL), which can improve the learning outcomes of class XI biology students on plant tissue material and can be used as an alternative learning model. This research uses classroom action research (PTK), which includes four stages: planning, implementing actions, observation,  and reflection, which aim to improve the learning process. PTK is an activity that involves testing an idea in practice, which can improve and increase the quality of the teaching and learning process. The application of the PBL model was able to improve student learning outcomes, especially in biology subjects with plant tissue material for class XI students at SMA N 2 Langowan. During the pre-cycle, the average value was 5.7. In cycle I, it climbed to an average value of 7.3. In cycle II, it further increased to an average value of 8.4. Meanwhile, the completeness of student learning outcomes in the pre-cycle was 20%, while in the first cycle, it was 67%, then grew again in the second cycle, specifically 87%. Based on the aforementioned research findings, it can be inferred that the implementation of the Problem-Based Learning (PBL) model has led to an improvement in the academic performance of Biology students at SMAN 2 Langowan.
