Getting Started with MIT App Inventor 2 | for Android

Getting Started with MIT App Inventor 2 App Inventor is a cloud-based tool, which means that you can build apps right in your web browser. This website offers all of the support that you’ll need as you learn how to build your own apps. The App Inventor software, or “service” is at ai2.appinventor.mit.edu. You can get there by clicking the orange “Create” button from any page on this website.

1. Setup Instructions: How to set up your phone for live testing (or, if you don’t have a phone, how to start the emulator).

2. Designer and Blocks Editor Overview: Gives a tour of the App Inventor environment.

3. Beginner Tutorials: Highly recommended as the best way to get started programming in App Inventor.

4. Packaging and Sharing Apps: After you have built an app, you can package it for your phone and you can share it with friends. What’s different in the new version of App Inventor? Find out what’s new App Inventor 2.

TAPS Resources: Mathematics Awareness Months-Sports is the THEME

April is Mathematics Awareness Month

The theme for 2010 is Mathematics and Sports

COD students can join in the fun by reading any of the following sports-related math articles here:

  1. Binomial Baseball “Programmable calculators can be used to play simulated baseball games. [] The use of random numbers to determine hits and outs introduces the student to the Monte Carlo method in a familiar context.”
  2. Designing A Baseball Cover “Problems in design, even those of a rather frivolous nature, can produce some very interesting mathematics. Consider the 130-year-old problem of designing the cover for a baseball. Early experimental work on this problem involved the freehand drawing of plane figures. We will use geometric insight and calculus to give a relatively easy solution of the problem in space. Next, a differential equation will be derived that gives a mathematical solution with plane figures, in the style of the early efforts. Finally, we will see how well trial and error have worked, by looking at the cover design that is currently used in the manufacture of major league baseballs.”
  3. Building Home Plate: Field of Dreams, or Reality? “In the moview Field of Dreams, Kevin Costner’s character, Ray Kinsella, considers building a baseball park in the middle of his cornfield. [] An assistant coach for my nine-year-old son’s baseball team, I was interesting to read in the official league rules the following specifications for home plate:”
  4. A Mathematician Catches a Baseball “In the game of baseball, what strategy does an outfielder employ to catch a fly ball? Recently, Michael McBeath and Dennis Shaffer, who are psychologists, and Mary Kaiser, a researcher at NASA, proposed a new model to explain how this task is accomplished. The model, called the linear optical trajectory (LOT) model, was developed and tested empirically by the three researchers, and it received national attention during the 1995 baseball season. In this paper, seeking to clarify what is written, we develop equations relating the motion of a fly ball to the motion of an outfielder utilizing the LOT strategy. In the process, we provide a mathematical foundation on which the LOT model can rest.”
