A series of random questions about structures on the current image is presented
when a student clicks on the 'Questions' button.
All questions ask the learner to click on the structure on the computer screen. If the question is answered correctly another question is presented. If not, the learner may attempt the question again or ask the 'pointer hand' to show them where it is, or Cancel the question. The Score since beginning the program is kept.
Figure 1. A random question is presented after a learner clicks on the Questions tool. If they click in the wrong place, they are offered a chance to try again or for the hand pointer to show them where the structure is.
