​​A unique way to share information, images with hotspots offer online learners the opportunity to interact with course content. Learners can click or hover on particular parts of an image and receive pop-ups giving them more information. Hotspots represent information in a particular context; thus, they fulfill the multimedia principle—use words and graphics rather than words alone—and the contiguity principle—align words to corresponding graphics (Clark & Mayer, 2016).

Game-based learning (GBL) is a learning experience, or set of learning experiences, delivered through gameplay or game-like activities with defined learning outcomes. GBL is often confused with gamification, which is the application of game elements to a non-gaming experience. GBL engages students cognitively, emotionally, behaviorally, and socioculturally (Plass et al., 2015). Many factors should be considered when designing GBL, including narrative, player positioning, and interactive design (Dickey, 2005).

Discussions are an impactful way to build engagement and discourse in asynchronous online courses. When properly designed, discussions can encompass the three pillars of engagement: student-content, student-student, and student-instructor. Asynchronous discussions allow students time to reflect prior to participating, which can lead to deeper insights and richer discourse. Moreover, when participating in discussions, students have the opportunity to collaborate with others, participate in an online learning community, and gain insights from others’ unique experiences and perspectives (Ransdell, Borror & Su, 2018). Facilitating multiple types of engagement in an online course can improve student motivation, satisfaction, and achievement (Dailey-Hebert, 2018).
