Say What? Math Edition

I have done a lot of thinking about an app that is both educational and useful.  I wanted the app to help students in a real and concrete way.  One of the areas I try to gradually help students with is mathematical language and literacy.  I encourage them to speak and use mathematical language with accuracy.  For example, when presenting a group project on limits of rational functions, I have found that students often use the words “top” and “bottom” as opposed to “numerator” and “denominator”.  I do not mark off their grades provided they (as a group) can come up with the mathematically accepted terminology which they inevitably do.  

The “Say What? Math Edition” app would be a tool for all levels of math students to practice and improve their math language skills.  My app will provide the user with an image of a mathematical construct such as a geometric figure, equation, graph, inequality, etc.  The user will then need to put into words what the construct portrays.  The app will then interpret the words exactly as they are said and create a new image.  The app will then let the user know if the two images match or not and depending on the settings, give the user a chance to adjust or correct as needed.  It could also include different modes such as fill in the blank and multiple choice.  I would also like the app to give users the option to share a “brag badge” on social media or via email.  This will allow for students to connect with one another.  This app has the potential to be utilized in many different ways.  

This app provides an opportunity for equity in that users are working to level the playing field regarding the use of mathematical terminology.  It is also equitable in that there are settings to allow for a different number of attempts for the user.  Perhaps a teacher or parent can set the number of tries based on the users ability.  The app should also provide information (written and/or video) regarding missed questions so the user can learn and then correct any errors on subsequent trials.  

There is great importance in speaking with mathematical accuracy.  I interviewed several people regarding this app idea and most said that it is important in some contexts, however in the opinion of some students, it is not as relevant in others.  For example, in places of business it is important to speak with mathematical accuracy.  Students cited examples of errors such as buildings and bridges collapsing and the consequences of injury to people as well as the expense of such tragedies to people in addition to the cost to rebuild.  One student also commented that errors in mathematical language could cause confusion which could prevent someone else from completing a task.  

Another important point was raised by an adult I interviewed regarding voice recognition.  There are many voice recognition tools available for modern convenience and as we look to the future, it is quite possible that voice recognition will become a more integrated part of everyday living.  As such, students should grow in their understanding and practice with speaking to a computer in a mutually understood language.  

According to the students I interviewed, the primary use of their phones is to connect with others.  As such, I wanted the app to match this student interest and provide students with a means to connect to others.  Allowing students the opportunity to share the “brag badge” not only allows them showcase their skills, but notifies students that someone else is able to help them.  If a student has posted their brag badge, they are letting others know that they understand the selected topic and are able to help.  The app can suggest potential helpers to a student in need of additional help.  The brag badge should have a setting that also indicates that the student is interested in helping their classmates, or perhaps the teacher can set that expectation for the class.
