“…Relative to formal learning, informal learning is not well researched (Eraut, 2004; Merriam, Caffarella and Baumgartner, 2009), is largely anecdotal (Noe, Tews and Marand, 2013), characterized by diffuse definitions (Shaffer, DeGeest and Li, 2016) and described in vague terms with no clear conceptual boundaries (Wolfson et al ., 2018). As such, informal learning research faces a number of challenges: the difficulty in measuring informal learning (Schurmann and Beausaert, 2016); the absence of effective syntheses of the core concepts (LeClus, 2011); the diversity of conceptual frameworks and measurement regimes (Cerasoli et al ., 2018; Wolfson et al ., 2018); the challenge of better facilitating informal learning (Choi and Jacobs, 2011); and the incorporation of situational influences such as gender (Ostrouch‐Kaminska and Viera, 2015; Thomas and Moisey, 2006), culture (Kim and McLean, 2014) and sector (Coetzer, Kock and Wallo, 2017, 2019; Jeong, McLean and Park, 2018). These challenges are reflected in the diversity of theoretical framings used in informal learning research (Jeong et al ., 2018; Wolfson et al ., 2018).…”
