Studies on engagement uncovered that while students may be physically present and appear to be actively involved in using the technology tools, in reality they might still be cognitively disengaged from the learning goals (Linnenbrink &Piintrich, 2003).
This reminds me of using Kahoot! in my classroom. Even if students do not know how to do the material, they are engaged and just select an option in hopes they get it right and win the game. Guessing is a popular alternative students learn instead of mastery.
