Helios features in-game assessment through inquiry levels,
via hypothesis selection and explanation, to measure if the
game is teaching the players as they progress through the
game. The two forms of inquiry are shown in Fig. 3c and 3f.
In both forms, the player works with an in-game peer to get
through a door, locked down by B.I.L.L. Levels like 3c have
the player selecting the correct answer from images on the
screens at top so Cindy can input it as a code to open the door.
The "Boss Level" like 3f, has B.I.L.L. stopping the player and
friend Wesley and giving them a new set of puzzles. In these
puzzles, the player (through choice options at left) and Wesley
(through choice options that will appear at right) must come to
the same answer as to why the beam is either balanced, or
unbalanced.
