Mathematics learning often poses challenges due to low student interest, resulting in reduced participation and outcomes. This study aims to enhance students' learning interest through the application of Problem-Based Learning (PBL) assisted by Kahoot. Using a Classroom Action Research (CAR) approach, the study was conducted in two cycles, each comprising planning, implementation, observation, and reflection. Results showed an increase in students' learning interest from 51% (low) in the pre-cycle to 67% (moderate) in Cycle I, and 81% (high) in Cycle II. The findings demonstrate the effectiveness of PBL assisted by Kahoot in fostering interest and engagement in mathematics. Teachers are encouraged to integrate gamified tools like Kahoot and tailor learning strategies to students' needs.

This study aims to enhance the English speaking skills of 12th-grade students at SMA N 15 Semarang on the topic of social media effects through the Problem-Based Learning (PBL) model combined with the Snakes and Ladders game. Conducted in two cycles, each consisting of planning, implementation, observation, and reflection stages, the study showed significant improvements. The average speaking score increased from 63 in the pre-test to 72 in Cycle I, and further to 75 in Cycle II. Additionally, students achieving the minimum passing grade (KKM) rose from 60% in Cycle I to 80% in Cycle II. The interactive approach of PBL and Snakes and Ladders fostered active participation and confidence, demonstrating the effectiveness of integrating games and problem-solving strategies to improve engagement and speaking proficiency.

PENERAPAN DISCOVERY LEARNING BERBANTUAN MEDIA BOLA, BALON, DAN TTS UNTUK MENINGKATKAN AKTIVITAS BELAJAR PESERTA DIDIK

Inca Pritonasya Milaningsih — 2025-01-12

This study aims to improve the learning activities of Class XI-5 students at SMA Negeri 15 Semarang in chemistry lessons by implementing the discovery learning model assisted by teaching aids (balls and balloons) and crossword puzzle (TTS) media. Initial observations identified several issues, including low student activity levels, averaging only 37.22%, lack of enthusiasm during lessons, and minimal attention during group presentations. Additionally, the teacher faced time constraints in providing in-depth explanations, making it challenging for students to understand abstract chemistry concepts. This study employed the Classroom Action Research (CAR) method using the Kemmis and McTaggart model, consisting of four main components: planning, action, observation, and reflection. In Cycle I, the use of teaching aids and media in the discovery learning model effectively increased activity to 50.48%, though it did not meet the target. Improvements were implemented in Cycle II with more interactive learning methods, such as crossword puzzles, which increased the average activity level to 87.71%, surpassing the success criterion of 80%.

Penerapan Model Project Based Learning Sebagai Upaya Meningkatkan Motivasi dan Prestasi Belajar Kimia Siswa Kelas XII

Wiji Dwi Utami — 2025-01-12

This research is classroom action research carried out in two cycles. Each cycle consists of action planning stages, action implementation, observation/data collection and reflection. The research subjects were students in class XII-5 of SMA Negeri 4 Semarang for the 2024/2025 academic year. This research aims to increase student motivation and learning achievement in chemistry subjects on the concept of Electrochemical Cells. To achieve this goal, researchers applied the Project Based Learning learning model by creating a simple experimental or practicum project. The instruments used in this classroom action research are learning motivation questionnaires, video documentation and cognitive tests. The research results show that the average percentage of student learning motivation in the pre-cycle was 64.8%, then in cycle 1 it increased to 91% and cycle 2 to 95.6%. Meanwhile, the data on student learning achievement after taking action by applying the Project Based Learning model in cycle 1, the average was 83, then in cycle 2 it became 76. The chemistry learning achievement of these students experienced a decline due to several reasons, namely in cycle 2 the material discussed are Electrolysis Cells and Faraday's Law, where the content is more complex and students do not fully understand the prerequisite material.

PENINGKATAN MOTIVASI BELAJAR PESERTA DIDIK MELALUI PENERAPAN MODEL PEMBELAJARAN CORE DI KELAS X SMA NEGERI 15 SEMARANG

Muhammad Naufal Majid — 2025-01-12

This study aims to identify and improve students' learning motivation through the implementation of the CORE learning model based on an active and collaborative learning approach. This study was conducted in two cycles, with the subjects of the study being grade X students in a high school. In the first cycle, students' learning motivation was indicated to be low, with an average score of 2.8 on a Likert scale of 1-5, which was reflected in minimal participation, low initiative to ask questions, and less than optimal quality of assignments. In response to these findings, the second cycle involved the implementation of various learning strategies, such as providing simple rewards, using interesting learning media, a personal approach, and dividing groups based on student abilities. The results of the second cycle showed a significant increase, with the average score of student motivation increasing to 3.9, as well as positive changes in class participation, quality of interaction between students, and better assignment results. This increase in motivation not only impacts student engagement in learning, but also improves their understanding of the material being taught. This study concludes that learning strategies that actively involve students can be effective in improving learning motivation, as well as providing a basis for further development in the implementation of more innovative and inclusive learning.

Nurkintan Aprilia — 2025-01-12

The application of the contextual Problem-Based Learning (PBL) model is considered to enhance students' conceptual understanding of redox reactions and voltaic cells. In the context of the 21st century, which demands critical thinking, collaboration, and creativity, a learning approach that connects theory with real-life situations is crucial for developing these skills. This study aims to optimize the effectiveness of the contextual-based PBL model in enhancing students' conceptual understanding. The method used is reflective classroom action research (CAR), with two cycles based on the stages of Kemmis and McTaggart, utilizing assessment results and learning observations. The research results show a significant improvement in students' conceptual understanding. The average student score increased from 59.03 in the pre-cycle to 81.14 in cycle 1, and 88.81 in cycle 2. In addition, the percentage of student mastery also increased, from 41.67% in the pre-cycle to 66.67% in cycle 1, and reached 83.33% in cycle 2. This improvement demonstrates the effectiveness of implementing the contextual-based PBL model in enhancing students' conceptual understanding, particularly on complex materials such as redox reactions and voltaic cells.
