This article discusses the Develop phase. Data collection techniques using a questionnaire technique. From the results of the study it can be concluded that the Digital Worksheet is appropriate to be used in Science III lectures with the average results of expert validator ratings on each aspect as follows: content worthiness of 32.25 (Very Good), Conformity of presentation with learning approaches of 36 (Very Good), Conformity with didactic requirements is 18.5 (Very Good), Conformity with construction requirements (linguistic) is 20 (Good) and Conformity with technical requirements (graphic) is 26.75 (Very Good).
