The APUS Research and Academic Excellence team has hosted a series of webinars on various topics, such as how to write the thesis/capstone paper, academic writing, researching and writing a literature review, etc.
While these webinars are aimed at graduate students at APUS, they are useful (and completely open) to undergraduates, too.
To find them, visit the the Master's Studies or Doctoral Studies page in the APUS library. Scroll down to "Graduate Studies Writing Modules & Presentations.
Recordings of previous webinars are available under "Research Presentations" and "Graduate Professional Development."
