Abstract

This study aims to enhance student learning outcomes by utilising the E-Module media, specifically the Book Creator application, in conjunction with the Basic Laboratory Work Techniques material for class X of the Industrial Chemical Engineering Department at SMKN 1 Tapen. The research instrument used was a knowledge test sheet. E-module media based on Book Creator is declared effective if there is an increase in student learning outcomes before and after treatment. The study's results showed that an increase in student learning outcomes was observed in the average class value and the percentage of completion after students were given learning materials using E-Module media, specifically the Book Creator application, for the Basic Laboratory Work Techniques material. Before the action was taken, the percentage of completion reached 45%, with an average value of 66. In cycle I, the percentage of completion reached 72%, with an average value of 76. Then, in cycle II, the percentage of completion reached 91%, with an average value of 88.

Abstract

Chemistry is often perceived as a difficult subject by most students. This is largely due to the complexity of the material, which requires deep understanding and strong analytical skills. Based on the initial observation, several issues were identified, ranging from students appearing disengaged to low learning outcomes. To address these problems, the researcher proposed an alternative solution by implementing the Teams Games Tournament (TGT) type of Cooperative Learning model in the learning process. This study aims to examine the effectiveness of applying the Teams Games Tournament Cooperative Learning Model to the Reaction Rate topic. The subjects of this research were 27 eleventh-grade students at the private Islamic Senior High School (MA) Al Riyadhul Janah. The Classroom Action Research (CAR) was conducted in two cycles, each consisting of four stages. The success indicators of this study were an improvement in the teacher’s performance scores and an increase in the students’ average learning outcomes, reaching above the Minimum Mastery Criteria (KKM), which was set at 75. The findings revealed that the implementation of the Teams Games Tournament Cooperative Learning model was effective in improving students’ learning outcomes. In the second cycle, the average score increased to 79, showing a 31.6% improvement compared to the initial observation. However, the first cycle experienced a decrease of 13.3% from the initial results. This decline was caused by several factors, which were then addressed through reflection and improvement in the subsequent cycle. After implementing revisions in the second cycle, the Classical Mastery Level reached 70%, indicating that the research was deemed successful as it had met the predetermined success criteria.

Abstract

This research is motivated by the low level of student engagement and learning outcomes of eighth grade students at MTs Kalimbuah on the Human Excretory System. This problem is thought to be caused by the learning process still using conventional methods, where teachers play a more dominant role in the teaching and learning process and students tend to be passive. Furthermore, the human excretory system material is relatively complex, requiring in-depth understanding. This research used the Classroom Action Research (CAR) method, which was implemented through two cycles. Each cycle began with the planning stage, followed by action, observation, and ended with reflection. The learning model applied was Discovery Learning, which is designed in such a way as to encourage students to be active in discovering concepts through a process of exploration and investigation. The results of this study indicate that the application of Discovery Learning successfully increased student engagement during the learning process. This success was marked by increased student participation in discussions, answering questions, and summarizing the material. The percentage of classical class completion also increased, from 57% in the first cycle to 86% after the second cycle. Based on these results, it can be concluded that the use of the learning model Discovery Learning effective in improving the quality of learning on the human excretory system. Therefore, Discovery Learning can be used as an alternative learning model in learning science material.
