Description: Computers are everywhere in our daily lives, powering everything from social media to AI-driven applications. As technology advances, we need more computing power to handle complex tasks, leading to a key challenge: how can we use multiple computers to process tasks more efficiently? While it might seem that doubling the number of computers should double the speed, reality is more complex. Just as teamwork in a large company requires coordination to be effective, parallel computing depends on synchronization to maximize efficiency. This workshop introduces participants to fundamental programming concepts through two interactive activities that make these ideas accessible and engaging. The first activity is a paper-based board game that demystifies programming and illustrates how a single computer processes instructions. Using just pen, paper, and marbles, players step through a program, observing how computers follow a sequence of operations. This activity provides an accessible and interactive way to grasp fundamental programming concepts without the need for a computer. The second activity is a multiplayer video game for two players that highlights teamwork. This challenge makes it clear how coordination impacts performance, giving players an intuitive understanding of how parallel computing works without complicated explanations. Understanding what happens behind the screen helps break down the mystery of technology and builds problem-solving skills. The concepts covered in this workshop, such as logical thinking and problem-solving, also apply beyond programming. This workshop is designed for people with no programming knowledge and offers different levels of difficulty to suit various audiences. It encourages critical thinking, problem-solving, and teamwork in an engaging and accessible way, demonstrating complex computational principles through educational games.
