Proven effectiveness

What differences are there between Think!Think! compared with the general digital learning materials?

Think!Think! differs from many other apps because it helps users acquire skills and knowledge in subjects such as calculation. Think!Think! is an educational material with a core design that fosters a sesnse of thinking and a motivation to learn.

A sense of thinking is a very important ability for effective learning. For example, a child with good sense of thinking will realize that, when learning multiplication and division, they are in fact, dealing with the same thing but from a different angle. From this, the child will be able to grow rapidly independently. Furthermore, as we live in a generation where anything can be learned online, there is a large difference in academic performance depending on one's level of motivation. Think!Think! fosters a sense of thinking along with a motivation to learn by tackling high-quality puzzles and three-dimensional and graphic problems, all whilst having fun.

Can a digital content be more effective for learning than paper-based content?

Yes! When using Think!Think!, users can take full advantage of digital technology that exceeds the limits of paper-based content. This allows a wide range of people to have access to learn right at their fingertips.

Users can quickly develop a sense of thinking that helps them assemble 3D shapes in their heads or imagine all sides of a cube when it is flat. Think!Think! helps users gain a sense of thinking and visualization through various games where you can rotate objects, cut shapes into smaller pieces, etc., only things that can be done using technology. In addition, Think!Think! Is able to tailor the level of problems to each user and give real-time feedback. This far exceeds the limits of paper-based content and users are able to learn more effectively.

Of course paper-based content has its own benefits, and at Wonderfy, that is why we created WonderBox. WonderBox is a monthly STEAM-based subscription box that combines digital and paper-based content. This is only available in Japan at the moment.

Do you have any tips on how to use Think!Think! in the most effective way?

We recommend encouraging your child in a positive manner.

To develop critical thinking skills, your child needs to be able to say, "I want to try it!" and "I can do it!" It is of utmost importance for your child to concentrate on the problem with the feeling of "I want to do it!" Forcing children to do things they don't want to do or with little interest in is not beneficial to their learning process and, therefore will not bring out their full potential. Focusing on your child's efforts and praising them by saying, "That's amazing!" and "You did a great job!" will increase your child's motivation and they will continue to improve. It doesn't have to be everyday. Even if your child only says "That was fun!" or "So annoying!" you should continue to encourage them in a positive manner.

I'm not good with critical thinking or STEAM subjects, so I have little confidence in my ability to teach them to children.

The strength of our app is that children can work on problems completely by themselves. There are no requirements for parents or guardians to explain anything.

Think!Think! is designed so that rules can be understood intuitively, and the problems are tailored to each child's individual level. Should your child have a hard time with a particular question, you can guide them toward the hint button on the screen.
Each time your children solve a puzzle, they can see a visualization of the problem on the screen. For example, a problem could show how a 3D object is cut to make a cross-section or how a net is assembled. Even if, at first, the concept is difficult to understand, they will gradually be able to visualize abstract ideas and concepts in their head by themself.
If you're a parent or guardian, please encourage your children's efforts by saying, "That's great!" and " Keep trying!"
