:I think kids learn better by studying for tests. If you actually sit and study what you are supposed to learn, you'll remember it. Hands-on projects might end up making a kid feel stressed if they are trying to finish on time, and If you are stressed, you might not learn as much.
:When people study, they remember what was in the book. If they know they have a test, they will most likely to take notes on all the important information to help them with the test, so they will learn it better.
:With a hands-on project, you can be creative while you learn. It's also a lot more fun than sitting at a desk with flashcards. Plus, with a hands-on project, you can learn more than you expected. It's more satisfying to learn on your own without someone explaining it to you.
:Hands-on projects are better. When you are studying for a test, it can get boring and then you can get distracted(注意力分散的). You learn better doing projects because it is not boring and you experience new things depending on what you are doing.
:I think kids learn hands-on projects because they have to consider the topic, instead of just memorizing information that they'll forget about after the test. Also, completing a project is good for spending time with your friends or family.
