Which practice refers to conducting several practice sessions over time?

The practice that refers to conducting several practice sessions over time is spaced practice. This approach emphasizes the distribution of practice over time, allowing for intervals between sessions rather than cramming all the practice into a single block of time. Research has shown that spaced practice can lead to better retention of information and skills compared to massed practice, where sessions are conducted in a condensed manner without breaks.

By spacing out practice, learners can benefit from the time in between sessions to rest and consolidate what they've learned, leading to improved long-term memory and skill proficiency. This method is particularly effective in various fields, including education and skill development, as it supports deeper learning and better recall when the information or skill is needed later.
