Traditional paper science notebooks have served the purpose of engaging learners in the scientific practices, however, as with many things, paper is being replaced by digital. This study examined the digital notebook entries of students to consider the affordances and limitations of digital science notebooks versus traditional paper science notebooks. Affordances were related to the use of audio, ability to copy and paste, take photographs, and include material from the internet. Limitations included the time it took students to write and/or draw tables, and the potential learning opportunities lost from close observation through drawing to photographs. This study highlights how a digital science notebook can also integrate technology in a manner that promotes active learning and critical thinking. Based on the notebook entries examined, we suggest that the affordances outweigh the limitations and encourage further research on digital science notebooks.
