Digital Dictionary is an inseparable part of education and teaching. For this reason, higher education institutions are more enthusiastic about measuring the retention of Arabic language education students in learning activities. This study aims to measure the retention of Arabic language education students by developing a Digital Dictionary in tertiary institutions. This research is research and development with the Gagne and Briggs model; this research has steps such as analysis, identification of needs, setting general and specific goals, identifying alternative ways of meeting needs, designing components of the system, analysis (required resources, available resources, constraints), activities to overcome obstacles, select and develop materials, design research procedures, field trials, adjustments, revisions, further evaluations, summative evaluations, operational implementation and produce Digital Dictionary teaching materials. The subjects of this study were 40 students and two educators. The results of this study are proven by the results of written tests carried out after using the Digital Dictionary; the results are that 69.5% of students can use the Digital Dictionary tool, which is easy to carry anywhere and can increase student learning motivation. Thus, the Digital Dictionary developed using the Gagne and Briggs model can be used properly. The limitation of this research is that the researcher only conducts research by creating a Digital dictionary in one educational institution.
