“…This result does not mean that interest in learning science emphasized by frontline researchers (e.g., Jack et al, 2014Jack et al, , 2017Lin et al, 2012Lin et al, , 2013Palmer, 2004) is no longer important. Instead, it reveals that as soon as learners' interest is triggered, follow-up engagements of deep-learning such as learning opportunities enabling dialectical nature of mediation (Sakellari, 2015), transdisciplinary connection, mediated engagement, meaningful discovery, and selfdetermined inquiry (Jack et al, 2017) play a critical role in promoting their long-term scientific competency and environmental action. One possible implication of this finding is that when learners' interest is triggered by the exhibitions, demonstrations, or aesthetic perceptions, well-designed follow-up learning opportunities such as dynamic interactions between the learning resources and the learner or reflective evaluation on the learning content and context (e.g., Lin, Hong, Chen, & Chou, 2011;Lin et al, 2012) are more likely to promote learners' advance learning outcomes.…”
