Dr How Meng Leong, Research Fellow at Office of Education Research together with Prof Looi Chee Kit, published a paper titled “Using Grey-based Mathematical Equations of Decision-making as Teaching Scaffolds: from an Unplugged Computational Thinking Activity to Computer Programming” in the International Journal of Computer Science Education in Schools.
In the paper, they discussed how problem-solving strategies in educational settings are often conveniently attributed to intuition. However, it is also documented that computer programmers might have difficulties describing their intuitive insights during problem-solving using natural language (such as English), and to subsequently convert what has been described using words into software code. Hence, a more analytical approach using mathematical equations and descriptions of Computational Thinking (CT) is offered in this paper as a potential form of rudimentary scaffolding, which might be useful to facilitators and learners of CT-related activities.
The decision-making processes during an unplugged CT activity are delineated via Grey-based mathematical equations, which is useful for informing educators who may wish to explain to their learners about the various aspects of CT which are involved in the unplugged activity. They could then simultaneously use these mathematical equations as scaffolds between the unplugged activity and computer code programming. This theoretical manuscript may serve as a base for learners who embark on a software programming activity that is closely associated to the unplugged CT activity.
