At some point developing tutorials for more and more services becomes redundant. Unless I discover a service that provides what I consider more powerful tools, I have decided to offer a single page with summaries of other services. I have also decided to include services that are similar to what I describe in my book, but limit the content to that which is provided by the instructor rather than from a third party.
Playposit
Playposit allows educators to add comments and questions to videos after uploading an URL. Existing layered videos can also be accessed by grade level, subject, and standard. After development, videos can be organized by unit within class. Students are assigned to classes and student responses to questions are saved for teacher examination. There is a free and premium version. Features described here are available in the free version.
Videonote.es
Videonot.es is an online service for adding notes to video. The service is designed to save these notes to Google Drive. The saved file contains the annotations and the link to the original video. When this file is opened using the Videonot.es app or service, the viewer will see the combined notes and video. Viewer must also have access to Videonote.es. To control access, share a Google Drive folder containing these saved files with those you wish to provide access.
EdPuzzle
EdPuzzle shares many features with other video layering tools I have described, but also is similar to Insert Learning in offering tools teachers can use to set up a class, make assignments to individual students, and track student progress, Insert Learning focused on web pages and EdPuzzle focuses on video.
Annotation Studio - MIT Digital Humanities Project
The Annotation Studio Digital Humanities project from MIT is an online option specific to content uploaded by educators and so is different than the approach I have described in my own work.
The Humanities project is less based in quantitative research and focuses on the argumentation style of those from the humanities. MIT has generated a White Paper that describes Annotation studio, provides a tutorial on the service, and provides additional comment justifying such activities that may interest educators. The program was developed at the university level, but has been used in high schools.
