1. Struggle helps them learn how to learn.
There is a difference between regurgitating materials on an test vs. understanding the process of learning. Students who aren’t given the opportunity for independent learning don’t acquire the skill of HOW to learn and how to examine a skill from different perspectives. The teacher stands in the way of the student’s natural curiosity.
2. Independent learning focuses on the process and not just the answer.
The process of learning is exciting can be interrupted when the focus is on getting the right answer. Instead we should focus on the right process. Our children can develop a growth mindset that failure is not the end and it helps you to grow.
3. Intrinsic Motivation.
The world isn’t going to cheer us all on always. When things get tough, students will develop motivation from within than motivation from the external. At some point in the learning cycle you want the student to be actively engaged in the learning process themselves so that they can get that sense of gratification. They will realize that the right answer they got was because of the work they did themselves. Even if they make mistakes, they will still be able to evaluate which part of the process didn't work.
4. Independent learners are more aware of their own strengths and weaknesses.
Some of the most honest people on the planet are children. They are very aware of their weaknesses. You know this because as soon as you release them to do a few problems on their own they will raise their hand and say, "I can't do this." or "This is too hard." So I always tell them complete the problems you know first. This builds their confidence to try the problems that are harder.
5. Students learn how to teach others.
Students love being the teacher or the expert. They develop communication skills and confidence in knowing that they are great at something and others look up to them. The other students can also chime in with questions or more explanation. They can even give advice on alternative ways to solve problems. This is definitely a win-win and cooperative learning at its best.
