Design suggestions needed to create a MathBuilder framework
- by Darf Zon
Let explain what I'm trying to create. I'm creating a framework, the idea is to provide base classes to generate a math problem.
Why do I need this framework? Because at first time, I realized when I create a new math problem I always do the same steps.
Configuration settings such range numbers. For example if I'm developing multiplications, in beginner level only generate the first number between 2-5 or in advanced level, the first number will be between 6- 9, for example.
Generate problem method. All the time I need to invoke a method like this to generate the problem. This one receives the configuration settings and generate the number according to them. And generate the object with the respective data.
Validate the problem. Sometimes the problem generated is not valid. For example, supposed I'm creating fractions in most simplified, if I receive 2/4, the program should detect that this is not valid and must generate another like this one, 1/4.
Load the view. All of them, have a custom view (please watch below the images).
All of the problems must know how to CHECK if the user result is correct.
All of this problems has answers. Some of them just require one answer, anothers may require more than one, so I guess a way to maintain flexibility to the developer has all the answers he wanna used.
At the beginning I started using PRISM. Generate modules for each math problem was the idea and load it in the main system.
I guess are the most important things of this idea.
Let me showing some problems which I create in a WPF standalone program. Here I have a math problem about areas. When I generate the problem a set to the view the object and it draw it.
In beginner level, I set in the configuration settings that just load square types. But in advance level, can load triangles and squares randomly.
In this another, generate a binary problem like addition, subtraction, multiplication or division.
Above just generate a single problem. The idea of this is to show a test o quiz, I mean get a worksheet (this I call as a collection of problems) where the user can answer it.
I hope gets the idea with my ugly drawing.
How to load this math problems? As I said above, I started using PRISM, and each module contains a math problem kind. This is a snapshot of my first demo.
Below show the modules loaded, and center the respective configurations or levels.
Until momment, I have no idea to start creating this software. I just know that I need a question | problem class, response class, user class.
But I get lost about what properties should have to contain in it.
Please give a little hand of this framework. I put much effort on this question, so if any isn't clear, let me know to clarify it.
