An online system provides for the teaching and learning of step by step solutions to STEM problems. The system comprises at least one tablet computer linked to at least one computer readable storage medium by a communication network. The computer includes an input device and a touch sensitive screen for receiving and displaying handwritten input. A system user inputs the computer with the steps of a step by step solution to a STEM problem by handwriting math expressions and sketches on the touch sensitive screen. The system evaluates and automatically color codes each step in accordance with a color coding protocol stored in the computer readable storage medium as each step is entered into the system. The color coding provides visual feedback which identifies correct steps, erroneous steps, and intermediate steps in the solution. Teachers use the feedback when teaching STEM solutions and students use the feedback when they are practicing and assessing their own solutions.
