MIT Fold 
"Self-guided, blended learning testing labs examining property measurements and variables."
Lab Description:
The folding endurance is the number of times a sample can be folded prior to it breaking. Fold endurance is thought to be a measure of the toughness of the paper sheet.
Scope and Learning Objectives:
These self guided testing labs and video modules demonstrate the procedures used to test paper and board. They will also provide some background about the property being tested. The overall learning objective is to increase your understanding of why and how these tests and procedures are performed.
The outline you should follow for each lab is to learn the background information on the property being tested, note the TAPPI standards that are referenced
TAPPI Standard (T511),or Useful Method then view the video on the correct testing procedure. Sample data is provided. Some of the labs will require calculations and analysis of data, and other labs will provide final data without calculations. A short set of thought questions is included at the end.
