Using Education Source you can batch search relevant journals such as Electronic Journal of e-Learning, Journal of Educational Technology & Society, TechTrends: Linking Research & Practice to Improve Learning, and Journal of Educators Online.

As in the search above, Education Source will autosuggest phrases to help you build a search with additional keywords to describe your topic. This search resulted in too many results to scan so I limited my search to a date range 2015-2018 and Scholarly (Peer Reviewed) Journals.
These options are available at the lower left of what you see in this screen capture in Education Source.
