Abstract: In one general aspect, a method for generating a digital textbook can include receiving, by a computing device, a time-based transcript of a video of an online lecture, receiving a time-based thumbnail image subset of images included in the video of the online lecture, and displaying at least a portion of the transcript including a particular word. The method can further include receiving a selection of the particular word, determining a first thumbnail image and a second thumbnail image associated with the particular word, displaying the first thumbnail image and the second thumbnail image, receiving a selection of the first thumbnail image, and modifying, based on the selection of the first thumbnail image, the time-based transcript by including the first thumbnail image in the time-based transcript. The method can further include storing the modified time-based transcript as the digital textbook.
