Why spend thousands of dollars on a private physics tutor when you can receive the same feedback on your iPad for a fraction of the cost?

✭✭✭✭✭ – "A Winning App – Step 2 Step should be in the electronic backpack of every high school physics student." – www.physicsclassroom.com

LEARN PHYSICS WITH STEP-BY-STEP TUTORING

—————————————

Created by physics teachers to help students prepare for tests, Step2Step Physics – Mechanics walks students through 38 question types, with 4 versions per question type and a total of more than 350 question steps. If a student makes a mistake on a step, they are provided with feedback that is targeted to that specific mistake. This is the same feedback that students would receive if they worked with a private physics tutor.

SIMPLE CONTROLS

—————-

Step2Step Physics employs a variety of intuitive user interfaces designed to encourage “physics thinking”. Some of these include:

• Dragging labels onto a problem statement

• Tapping arrows to choose a direction

• Dragging terms to build an equation

• Typing in a numerical answer, and many more!
