I am a professor at the Université du Québec à Montréal and I have developed this application that can assist you in learning to identify the birds, the butterflies, the constellations or the stars.

For the learning to be efficient, it is important that you try responding to the questions as fast as possible, and keep yourself free from distractions or interruptions. You will have a few seconds to answer each question, and a few more seconds to review or learn the correct answer. Questions will be repeated several times in order to reinforce and monitor your learning. A pause screen will appear after approximately ten minutes. This pause can be as long as you wish. It is important to continue afterwards and reach the fourth pause screen, at which point you will receive your results.

Would you like to attempt identifying the birds, the butterflies, the constellations or the stars?

Birds     Constellations     Stars     Butterflies     Bird songs    

Before starting, please enter a username that you can remember easily and select your age bracket, gender, and approximate level of knowledge for the chosen subject. This level will determine the order and difficulty of the questions. It is recommended to always use the same username, and to commence with the beginner level before progressing over time.
