Abstract

This study incorporates classroom action research as a means to ascertain the enhancement of student learning results. The participants in this study consisted of 29 students enrolled in the XI IPA class at SMA Negeri 1 Touluaan. The study was conducted over two cycles. The findings from the initial cycle of research indicated that the students' learning outcomes were fully achieved, with a completion rate of 51.72% or 15 students successfully completing their courses. In contrast, the findings of this study reveal that the implementation of the Discovery Learning model, supported by audio-visual media, in teaching the respiratory system in human biology can enhance the learning outcomes of 11th-grade students in SMA Negeri 1 Touluan.

Abstract

Critical thinking skills are an important competency in learning biology, especially in biodiversity materials that require analysis, reasoning, and decision-making. This study aims to determine the influence of the Guided Discovery Learning learning model on the critical thinking ability of grade X students at SMA Negeri 2 Tondano. The method used was a quasi-experimental study with a pretest-posttest control group design. The sample consisted of two classes, namely the control class that was taught using the conventional model and the experimental class that received treatment with the Guided Discovery Learning model. Data were collected through pretest and posttest written tests, and analyzed using normality, homogeneity, and t-test. The results showed that there was a significant difference between the learning outcomes of students in the experimental class and the control class. The average posttest score of the experimental class was 81 higher than the control class of 63.5. In addition, the Tcal value of 4.65 is greater than the Ttable of 2.02 at a significance level of 0.05, which shows that the Guided Discovery Learning model has a positive influence on improving students' critical thinking skills. This result is also strengthened by a decrease in standard deviation which shows an equal distribution of understanding between students. This research contributes to the development of active learning strategies in biology education and suggests the application of this model to improve higher-level thinking skills. This model is also relevant applied to other topics in order to strengthen discovery-based learning and collaboration.

Abstract

This study aims to determine the influence of the Project-Based Learning learning model on student learning outcomes in Animal and Plant Cell material. The background of this research is based on the low achievement of student learning outcomes at SMP Negeri 1 Bolaang, which is caused by conventional learning methods that are still dominant and the lack of active involvement of students in the learning process. This study uses a quasi-experimental approach with a nonequivalent control group design. Two VIII classes were selected as samples, namely the experimental class treated with project-based learning and the control class taught conventionally. The instruments used were pretest and posttest essay tests. The analysis results showed a significant increase in the average learning outcomes in the experimental group (81.72) compared to the control group (76.72). The Mann-Whitney statistical test showed a significance value of 0.043, meaning that the two groups had a significant difference in learning outcomes. These findings show that Project-Based Learning encourages students' active engagement, creativity, and deep understanding of biological concepts. This research strengthens the evidence that project-based learning is an effective strategy for improving student learning outcomes and is relevant to the middle level science curriculum. Implicitly, teachers are encouraged to integrate this model in contextual and collaborative science learning.
