How to design games for education? Step 1: Problem identification

Today, my student asked how to design a courseware for learning integer at Form 1. To me courseware is a form of games for education. So I share my answer to her here: "You should begin with problem identification, by answering the following questions:

1. Why do students need to use your courseware (read as game here) to learn Integer? 
2. What are the intended learning outcomes under this topic?
3. Who will use this courseware (students or teacher)?
4. When and where will they use the courseware (in classroom or at home)?
5. How teachers normally teach integer in the classroom?
6. How would teachers teach if they choose to use courseware?
7. How do you want the users (teachers and learners) to feel when using the courseware?
8. What are the learning contents and design materials you need to deliver the contents and the feeling they expected?

I adviced her to work with an actual Math school teacher, or at least a trainee teacher. Let's wait and see what are her answers...
