Open collaboration is when two or more people come together to work on a project or task. This means everyone shares their knowledge and skills, and works together to create something together. It can be used in many different areas like education, technology, and science. An example of open collaboration is when two people create a website together. One person might make a design for the website and another person might code the website. They both have different skills, but they work together to create something new and better.
