This paper presents the evaluation of a web app (ENACT) developed to support users with no expertise in pedagogy, media, and/or technology in creating engaging pedagogy-informed open educational resources. The aim is to increase cultural awareness and linguistic skills development through the creation of, and engagement with, interactive cultural activities. The design, which is informed by both theory and user input, is implemented by building a user-facing layer on top of the existing H5P platform. Participants' input from the evaluation workshop supported the design decisions around the provided task structure and the design choices around interactive media used. This work contributes a system as a web app to support non-experts in creating engaging online activities of a cultural and linguistic educational value and design recommendations generalizing the research based on literature, user insights, the developed system, and an evaluation study with migrants, refugees, and asylum seekers.
