In this paper, TDs are analysed in a digital simulation-based Predict-Observe-Explain (POE) learning environment by using the likelihood statistic (L-stat). Some studies report that TDs have a negative association with students' self-efficacy and performance [44, 45] , yet [7] states that 'certain difficulties can enhance learning'. From Table 2 , the students with perceived difficulty of hard on two or more consecutive tasks are significantly more likely to have poorer learning outcomes than those who do not report such a transition. We find that medium TDs may lead to better learning outcomes and they often follow hard TDs. However, if tasks get too difficult for students, e.g., reporting hard on two or more consecutive tasks, then it can adversely affect students' performance.	./cache/cord-028411-vae865vj.txt	./txt/cord-028411-vae865vj.txt
