The research method used is a descriptive approach. The object of this study is the concept of chemical bonding in educational videos from YouTube channels. Three educational videos were analyzed and coded as Video A, Video B, and Video C, and were conducted offline in a classroom setting. The instruments used include a concept label identification table, a 2013 curriculum concept label identification table, a 4C skills indicator identification table, and a pedagogy identification table. The identification results were validated by lecturers from the Chemistry Education Study Program at the University of Palangka Raya. The results showed that the concept labels from the three analyzed educational videos amounted to 32 concept labels. The concept labels that align with the 2013 curriculum syllabus are 11 concept labels across Videos A, B, and C. Overall, the 21st-century skills most commonly developed are Communication skills in Video A, Collaboration skills in Video B, and Critical thinking and problem-solving skills in Video C. The pedagogy demonstrated by teachers in YouTube channel educational videos most frequently included indicators of effective, empathetic, and courteous communication with students in Video A, curriculum development related to the subject taught in Video B, and facilitating the development of students' potential to actualize their various abilities in Video C.]]>
