This is a simple CLI tool that can be run by an instructor to verify student answers on Unit Conversion worksheets.
After students turn in their completed worksheets, the teachers want to be able to enter the questions and student responses into a computer to be graded. Students will convert:
Temperaturesbetween Kelvin, Celsius, Fahrenheit, and RankineVolumesbetween liters, tablespoons, cubic-inches, cups, cubic-feet, and gallons
- The teacher must be able to provide an input numerical value, an input unit of measure, a target unit of measure, and a student’s numeric response.
- The system indicates that the response is correct, incorrect, or invalid. To be considered correct, the student’s response must match an authoritative answer after both the student’s response and authoritative answer are rounded to the tenths place.
