How to manage the learning processes?

Three-level learning systems: Each level has four modules.

For simplicity sake, the following part will demonstrate practices for one complete module.

What you have in a module?

Each module comes with a CT activity book and worksheets. The book has an illustrated story and practices to help learners to acquire the CT skills. The worksheets are for learners to solve problems with robots by applying the skills of CT.

What is "algorithmic skills"?

Computational thinking is not thinking about computers or like computers.
Computational thinking is about looking at a problem in a way that a computer can help us to solve it. Computational thinking skills can be separated into algorithms, decomposition, abstraction and pattern recognition. 
An algorithm is a sequence of instructions or a set of rules to get something done.
You probably know the fastest route from school to home, for example, turn left,  drive for five miles, turn right. You can think of this as an ‘algorithm'.

Decomposition

The process of breaking down a problem into smaller manageable parts is known as decomposition. Decomposition helps us solve complex problems and manage large projects. It makes the process a manageable and achievable one – large problems are daunting, but a set of smaller, related tasks are much easier to take on. It also means that the task can be tackled by a team working together, each bringing their own insights, experience and skills to the task.

Abstraction

Abstraction is about simplifying things; identifying what is important without worrying too much about the detail. Abstraction allows us to manage complexity.

Pattern Recognition

Computational thinking allows us to take a complex problem, understand what the problem is and develop possible solutions. Pattern recognition is one of the four cornerstones in CT, it is the skill to look for similarities among and within problems. We can then present these solutions in a way that a computer, a human, or both, can understand.
