Abstract

Learning is the process of interaction between teachers and students in educational institutions which aims to achieve the expected results, through educational interactions and the goals of knowledge, attitudes and skills. Teachers play an important role in learning by providing appropriate teaching materials. Current learning still prioritizes the role of the teacher and students' activities in class do not develop independently through discovery and thought processes. Therefore, to overcome this, learning resources that are integrated with information technology and based on student-centered learning models are needed. One model that can be applied to chemistry learning is the experiential learning model. This research is development research using a 4-D model. The research aims to produce an integrated augmented reality worksheet based on experiential learning on electrochemical cells material.

Abstract

Student-centered learning significantly influences students' learning and thinking abilities. However, in practice, many teachers still use conventional teaching methods, such as lectures, to deliver material. Conventional teaching is often chosen because it can quickly convey information and is easy to implement in the learning process. Learning activities are a process for students to enhance their abilities and skills. One of the essential skills students need to develop is critical thinking. This skill can foster cognitive aspects and improve students' problem-solving abilities. Critical thinking skills can be trained during learning activities. This study aims to determine students' critical thinking skills in conventional learning on hydrocarbon combustion. The research employs a descriptive quantitative method with a test instrument in the form of essay questions. Ennis's critical thinking aspects measure students' critical thinking skills. Ennis's critical thinking aspects consist of 5 aspects encompassing 12 indicators. The results of the study show that students' critical thinking skills in conventional learning are categorized as low with 52.80%.
