The question "Which is more important: prep or review?" is as meaningless as asking "Who do you like more, mom or dad?" It is common sense that both are equally important. We may understand something after hearing or seeing it once, but we cannot remember it perfectly. However, if it is a story we have heard before or content we are somewhat familiar with, it may be easier to remember after just one encounter.
TheIn 1885, German psychologist Hermann Ebbinghaus introduced the concept of the "forgetting curve" based on his research findings. According to this concept, information is quickly forgotten after initial learning. After one hour, we forget 50% of what we have learned, and by the end of the day, we forget 70%. Over time, the rate of forgetting slows, and after reaching a certain point, memory becomes relatively stable.
How can we escape the sea of forgetfulness? Most experts recommend revision. By repeatedly recalling information before it fades away from our memories, we can convert short-term memories into long-term memories. Revision videos help children fully internalize the material they have studied.
