I used to think that by creating a quiz app, you must have lots of screens and a screen for each question because I haven’t thought of using lists which reduces the number of screens. Now I think that in order to become a good coder, you must be lazy, to find a way you can do things much simpler like using lists to create a list of questions images and answers instead of having 26 screens and each screen for a question.
Many people at ISB geometry because of how complex it is to solve things like volumes circle areas and many others, when I was in elementary school, even I was. In order to solve this problem, I have designed an app that is both relevant to what 6th graders are learning and what 7th graders are learning, from this app, students can learn many things starting from the simplest geometry, area of basic shapes, to area and volume of composite shapes, this app is great because people are at different levels, my app starts from simple questions to hard ones unlike others that only features formulas for people better at math, this app is for everyone.
My app’s name is Geometria, Latin for Geometry. Geometria, has a front page, the very first question, in the textbox, it shows instructions that the format you write your answer in and others. After reading the instructions, they have to delete the instructions and write the answer in the textbox, the image is on the top, then is the question, then is the textbox where you answer your questions. On the right of the textbox, there are two buttons: the submit button and the next button, the submit button checks your answer. Next gets you to the next question.
Geometria mainly uses lists. Because of the lack of time, I only have three lists, there is the global QuestionList, global PictureList and the global AnswerList, the QuestionList is lists of question I want to put in my app in order from up to down, PictureList are lists of picture and AnswerList is the list of answers. I programed, when the next button is clicked, then to the next list, and when submit button clicked, it checks the answer in the AnswerList with the answer in the textbox, when it is the same, it says “correct!”. When it is not the same, it says “wrong!”
The strength of this app is that it gives the less skillful users an easy time on this app because the question goes from easy to hard. The weakness is that some of the more advanced learners may think this app is too easy and it is not fun. I wish in order to solve this problem, I should broaden the range of questions, I would wish to add surface areas, cylinders, spheres, cones, coordinate plane Check out this video!.App Using Tutorial
