What is the method called where students recall information freely plus additional prompts?

The method referred to is indeed commonly known as "free recalls plus probes." This approach involves allowing students to recall information they have learned in an open-ended manner, which encourages them to access their memory without restrictions. The "plus probes" part means that teachers provide additional prompts or cues to help elicit more detailed responses or to guide students who may be struggling with recall. This technique can enhance students' ability to retrieve information, as the prompts serve to jog their memory and encourage deeper cognitive processing of the material.

This method is effective in assessing not only retention but also understanding and critical thinking, making it valuable in educational settings. It combines freedom in the retrieval process with structured support, fostering a more comprehensive exploration of students' knowledge.
