“…Nine studies reported positive results in improving students' academic performances, learning outcomes and experiences (Buchs et al, 2016;Dart & Spratt, 2020;Li et al, 2021;Motz et al, 2021;O'Connell & Lang, 2018;Onji & Kikuchi, 2011;Pugatch & Wilson, 2018;Sinha et al, 2021;Smith et al, 2018). However, students' characteristics such as gender and contextual variables in the area of prior academic performances and behaviour (Li et al, 2021), the timing of interventions (O'Connell & Lang, 2018;Onji & Kikuchi, 2011), and the presented information exposed to students (Motz et al, 2021), were factors affecting the degree of nudge effectiveness. Meanwhile, the tenth study reported no effect on near-term engagement and a weak significant negative impact on long-term engagement, persistence, and performance (Baker et al, 2016).…”
