“…However, a full interactive animation, which also included the primary interactions of dragging and controlling the topographic instrument, was the most effective. Similarly, in the study with engineers given a Lego truck to disassembly,Akinlofa et al (2013, see Section 3.2) observed that the most effective learning condition was the interactive virtual space, where participants could drag the computer replicas of the Lego This primary interactive display was a better instructional format than two simpler secondary interactive visualizations (static pictures and video), where the users could only change the presentations' pace.Because interactive features can help understanding STEM concepts (e.g.,Wang, Vaughn, & Liu, 2011; but seePedra, Mayer, & Albertin, 2015), they must be controlled in unbiased static versus animation comparisons. However, sometimes statics cannot include as many interactive facilities as animations (seeTversky et al, 2002), which may limit the scope of research that can be conducted linking interaction with presentation types.…”
