Chemistry learning on electrolyte and non-electrolyte solutions remains abstract and difficult to visualize, requiring digital learning media that actively engage students in critical thinking. This study develops Quizlet-assisted digital flashcard media grounded in Contextual Teaching and Learning (CTL) to strengthen critical thinking skills. Using a research and development (R&D) design with the Lee & Owens model, the study evaluates feasibility through expert validation, teacher assessment, student responses, and learning evaluation tests with grade XII students. Results show very feasible media quality, strong student responses, and high levels of understanding.

Development of Digital Flashcard Learning Media Assisted by Quizlet Based on Contextual Teaching and Learning (CTL) Oriented to Critical Thinking Skills on Electrolyte and Non-Electrolyte Solution Material Riris Desinta Marsaulina Manalu *, Wilda Syahri, Muhammad Haris Effendi Hasibuan, Haryanto, Zurweni Department of Chemistry Education, Faculty of Teacher Training and Education, Jambi University, Jambi, Indonesia *e-mail: [ririsdesinta30@gmail.com](ririsdesinta30@gmail.com) Received: March 9, 2026. Accepted: April 6, 2026. Published: April 30, 2026 Abstract: Chemistry learning on electrolyte and non-electrolyte solutions is still abstract and difficult to visualize, so it requires digital learning media that can encourage active student involvement in critical thinking. This study aims to develop digital flashcard learning media assisted by Quizlet, based on Contextual Teaching and Learning (CTL), that are oriented towards critical thinking skills, to assess the feasibility of the media, teacher assessment, student responses, and to provide an overview of students' critical thinking skills after using the developed media. This research is a research and development (R&D) with the Lee & Owens model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The research subjects were grade XII high school students. The research instruments included validation sheets from material experts and media experts, teacher assessment questionnaires, student response questionnaires, and evaluation tests. Data were analyzed descriptively, quantitatively, and qualitatively. The results showed that material expert validation increased from 85% to 97% after revision, media expert validation increased by 90%, and teacher assessment increased by 90%, with a very feasible category. Student responses in the one-to-one trial were 86.6%, and in the small group trial were 86.25%, categorized as very good. The evaluation results, at 82.27%, indicate that students' understanding is in the very good category. Therefore, the digital flashcard learning media, supported by Quizlet and based on CTL, is highly suitable as an alternative learning medium for high school chemistry and has the potential to foster students' critical thinking skills.

Introduction Education is the main foundation for developing quality, skilled, and highly competitive human resources in the era of globalization. 21st-century education demands mastery of critical, creative, collaborative, and communicative thinking skills in response to the rapid development of technology and information. 21st-century skills are essential competencies that must be integrated into the learning process to prepare students for the Industrial Revolution 4.0 and Society 5.0 eras. One of the main aspects of 21st-century learning is the thinking and work skills that students must master. These thinking skills include creativity, critical thinking, problem-solving, and decisionmaking. While working skills are the ability to work in a global and digital world, students must be able to communicate, collaborate, and work with individuals, communities, and networks. Students must also be able to master the tools for working [1] . Improving the quality of human resources (HR) through education focuses on developing higher-order thinking skills (HOTS), a crucial competency for preparing graduates to compete and adapt to changing times. One form of HOTS is critical thinking skills. Critical thinking skills are essential for problem-solving and decision-making. Therefore, developing critical thinking skills is crucial for students to achieve optimal learning outcomes [2] . Students' critical thinking skills can be trained, measured, and developed through teacher-provided stimuli during the learning process. Each individual ha
