Overview 

Math has always been a special subject to children as well as the grown up. The subject requires the thorough understanding of basic concepts and logic . Many loves mathematics, but lots of them fears of doing tedious calculations. This is due to lengthy calculation and poor logical skills . So we wanted to make math more enjoyable

As a problem we wanted to make lengthy calculation into a fun and enjoyable experience.

With stakeholder we reframed our problem into achievable goal.

Business Value

Online Learning is an expanding market, with an Annual worldwide growth rate of 7.9% (2012-2016). The Market values worth 51.5 Billion dollar by 2016.

K-12 and postsecondary are two key sectors of the educational market. We were targeting kids from class 1 to 5 (K-12). Thus we find class 3 kid best represent the extremes of our users set.

Brainstorming

We brainstormed with full team and crated small games. We tested among ourself and selected one game that seemed most promising.

Concept

Story

There is a machine that create potion on each correct answer. This potion is used to feed monster. This monster does circus and you earn money. Since this was a big game, prior  that we tested our concept with a mini game. 

Final game 

  • In this game you have set of task  to complete
  • You earn money and potion on x machine.
  • Progress is shown on map

We had two skills on our game 

1) Maths skill- 

Gradient of math skill "Addition of one digit number to one dight number" to "Addition of 3 digit number to 3 digit number" 

2) Game skill - 

Time factor , Using power , Completing task, Fixed number

We took both of them and created a hardness curve, such that feeling of mastery can be generated.

User testing

User Testing-1

We did user testing based on similar Psychographics. We both used standard usability test ,as well as data analytic to refine our Ux-Ui and level design.

Notable Findings from usability testing

-  X machine digit representation was confusing.

- User were not able to identify goals

- Unable to buy and use power

We mined our user data and drew insights from them

User Testing-2

We did remote testing of our game. Data were analysed to find what we can improve on level design and UX-UI

Guiding Questions

  • Where are the major drop-offs are happening?
  • How many retries and what the reason of their failures?
  • Which level is difficult?
  • How we can ask our user to come back again?
  • how many of them are new and returning user? 

Some notable Improvements

UI Design

X Machine 

I found out that user was struggled to comprehend three digit number.

The goal and task was not clear

  • We changed the visual of 3 digit number.
  • The grouping of task and time was improved

Select power flow Improvement

Select Power

When user gets hooked they ignore goal . They don't even read goals and they were not using the power.

As a solution we made Linear flow to improved the visibility of the power and its power store.

Map Improvement

We observed major drop off on level five.

As a solution we put a secret gift to extent there session

Final Design

Result

Learning

Explain what you had learned, experienced, or simply how you felt during the project.

We have learn to test our idea fast. Once we test the idea we mitigate our risk fast. As a team we had a huge success in term of our intent. Some of our achievement and learning were 

  • Our user base didn't like calculation but they end up ding 300 addition 
  • learned the real power of data informed design complimented by classical user testing
