I am also copying Shah - Al - Mamun's post:
Before we get into Gamification, lets see first what are the common requirement for a game:
1. Goals
2. Instructions to be followed
3. Reward
So to gamify a lesson we need the following in order:
1. Set the lesson goal
2. Share the instruction for achieving the goals
3. Select a reward for the students which would give them the feeling of achievement
Easy right?
Do not worry much about the reward though, it can be a leaderboard which would include the students' name in order according to their performance. The leaderboard can be made with an excel sheet. Students are competitive and this leaderboard can really make them drive into the gamified lesson.
To judge the result use a simple rubric
I hope this will help making a lot of gamified lessons. Feel free to let me know if there is any confusion or simply let me know your feedback. Feedback is important for both teaching and learning
