Digital literacy practice in mobile learning based on PBL in human's heredity to enhance students' cognitive learning outcomes.

This Research and Development aim to produce PBL-based mobile learning (Problem-Based Learning) material for human heredity that is valid, practical, and effective by digital literacy practice to enhance students' cognitive learning outcomes. The development model is based on Lee & Owens with four stages: analysis, design, implementation, and evaluation. Material experts, media experts, and learning experts validated the product. Biology education practitioners and student responses assessed the practicality of the product. The product's effectiveness is evaluated from the implementation to students with a pre-experimental design. Data were collected using validation sheets for validity testing, practicality sheets for biology education practitioners, student response questionnaires, worksheets, pretests, and post-tests. The validation test results by material experts, media experts, and learning experts are 100%, 100%, and 98.96%, respectively. The results of the practicality tests by education practitioners showed 97.86%. In contrast, the results of student responses through one-to-one trials, small group trials, field trials, and pilot tests were 92%, 92.6%, 90.9%, and 90.5 %. By practising digital literacy up to 81%, students' cognitive learning outcomes due to the effectiveness test increase to 62%. The paired t-test showed a significance of 000<0.05, so there was a difference between the pretest and post-test data. The study results concluded that the mobile learning developed was very valid, practical, and effective by digital literacy practice to enhance students' cognitive learning outcomes. This media deserves to be an alternative media in biology learning. [ABSTRACT FROM AUTHOR]
