Due to the dramatic differences in viewpoint and scale between ground and aerial images, which make matching them directly nearly impossible, we perform an intermediate view-synthesis step to mitigate the matching difficulty.
One of the possible adaptations is to apply an adaptive question sequencing system, which matches the difficulty of the questions to the student's knowledge level.
Before the game starts, you can adjust some basic match settings, such as length, match type, difficulty, and venue.
Only a handful of soccer ranking systems exist, most of which rely on limited information: the number of goals scored in a match, the number of goals assisted, and some indices of a match's difficulty and importance.
Routes, matched for difficulty, were manipulated in terms of hand-hold design.
For other lessons, the pool of available questions did not contain a sufficient number that allowed an exact match in difficulty across the three-question set.
Pre-test and post-test versions were matched for difficulty by using the same cube nets for five problems on each and by using different cube nets that were matched for number of folds required for the remaining three problems.
Contrary to our predictions of independence between memory and inhibition, when matched for difficulty RT correlations between these were as high as 0.8, although accuracy correlations were less than half that.
Faces (F), objects (O; cars) and their phase-scrambled counterparts (SF, SO) were presented in a block design during a one-back task that was well matched for difficulty across conditions.
All three questions for a given lesson were multiple-choice, relevant to that day's lesson, assessed independent concepts (such that knowing the answer to one question would not facilitate knowing the answer to another question), and were reasonably matched for difficulty.
