Validity of Flashcards on Elements, Compounds, and Mixtures in the Context of Sumenep Kokot Broth as a Medium for Practicing Critical Thinking Skills
Abstract
Flashcards are a visual learning medium consisting of small, illustrated cards. The images are created by hand, from photographs, or by pasting existing images onto the flashcard sheets. Through observations conducted in the science subject, problems were found, namely, the ability of students to understand the material on elements, compounds, and mixtures presented by the teacher was still low, while the activeness and use of media were not varied because learning was still focused on textbooks, and the absence of flashcard learning media in this subject. The method in this study was development research, with the procedure taken using the ADDIE model. Based on the results of data processing, it was stated that (1) the content aspect of the material received a validity value of 91.67% with very valid criteria, (2) the presentation aspect of the material received a validity value of 87.50% with very valid criteria, (3) the language aspect received a validity value of 100% with very valid criteria, (4) the form aspect received a validity value of 100% with very valid criteria, and (5) the color aspect received a validity value of 81.25% with very valid criteria. Overall, the media expert validator assessed the media as very valid with a value of 92.08% so that the designed media can be used in learning.
