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

This research aims to determine the effectiveness of practicum activities to improve student learning outcomes at SMA Negeri 2 Tondano. This type of research is quantitative descriptive research that uses a survey method to describe and explain data based on the reality in the field. The research was carried out by distributing questionnaires to teachers and students, observation sheets, and practical activity sheets with data sources consisting of 30 students of class X Science 1, 30 students of class X Science 2, and biology teachers. Based on the research results, the level of readiness to obtain data for class X IPA 1 At the implementation stage of the practicum activities for class X Science 1 is 91%; the efforts made to improve the quality of practicum implementation are by improving practicum weaknesses such as the availability of tools and materials, good laboratory management, conducting evaluations, arranging implementation schedules and paying attention to laboratory layout in order to carry out practicum optimally. The factors that influence the quality of practicum implementation include student motivation, limited tools and materials, practicum schedule, availability of facilities and infrastructure, teacher's role in practicum activities, and students' active thinking.

Abstract

This study aims to analyze student activities and learning outcomes in the learning of Spermatophyta sub-material through practicum activities based on Exploring the Environment at SMP Negeri 4 Manado. The background of this study is based on the need for a contextual approach to biology learning and being able to increase student engagement actively. The method used was quantitative descriptive research with survey techniques, involving 20 grade VII students and 2 science teachers as respondents. The research instrument consisted of a closed questionnaire, an open interview, and an observation sheet. The questionnaire results showed that students responded very well to this learning method, with an average score of 83.4%. At the same time, teachers rated this approach as effective, with an average of 88%. Observations showed that students were active in practicum activities, enthusiastic in making observations, and involved in group discussions. The interview revealed that this environment-based learning strengthens students' understanding of biological concepts and increases scientific curiosity. The obstacles found include the accuracy of recording and the inequality of roles in group work. However, overall, exploring the Surroundings-based learning has been proven to positively impact student engagement and understanding, especially in connecting theory with real objects in the surrounding environment. The implications of this study emphasize the importance of applying contextual approaches in biology learning and suggest improving guidance strategies and recording of observations in the field for more optimal learning effectiveness.

Abstract

Biology education in high school has an important role in shaping students' science literacy and critical thinking skills. However, ecological material, particularly the topic of Ecosystem Components and their Interactions, is often considered difficult because it is abstract and not easy to observe directly. This research aims to improve student learning outcomes through the application of the Problem Based Learning (PBL) model, which emphasizes real problem-solving, collaborative discussion, and active involvement in the learning process. The research uses the design of Classroom Action Research (PTK) which was carried out in two cycles in class X of St. Rosa de Lima Catholic High School Tondano involving 10 students in the odd semester of the 2025/2026 school year. Data was collected through observation of teacher and student activities, learning outcome tests in the form of pretests and posttests, and learning documentation. The analysis was carried out descriptively, qualitatively, and quantitatively by calculating the average score, percentage of completion, and student involvement. The results of the study showed a significant increase. The percentage of teacher activity increased from 58.3% in the first cycle to 87.5% in the second cycle, while student activity increased from 45.83% to 83.33%. The average score of students also increased from 70% in cycle I to 90% in cycle II, with classical completeness reaching 90%. These findings confirm the effectiveness of PBL as a contextual Biology learning strategy, able to bridge ecological concepts with real life, and increase students' curiosity, cooperation, and critical thinking skills.
