The Richard Montgomery High School robotics team, Rocket Robotics, is excited to offer a free, 6-week coding course for middle school students, designed to introduce beginners to the fundamentals of programming and spark interest in programming and robotics. This hands-on course will cover the fundamentals of coding using one of the most popular programming languages, Python. Students will receive guided instruction over the 6-session course which will help them understand key concepts (such as basic Python syntax, working with and manipulating data, control structures like loops and if statements, and creating reusable methods) and prepare them to further advance their coding skills.
Experienced high school mentors will guide the participants, providing personalized support and encouragement. With each session building on the last, students will not only gain a solid foundation in Python programming that they can apply in robotics and other coding projects, but also the confidence to explore further in the world of technology and robotics. Whether you’re new to coding or looking to strengthen your skills, this course will provide a supportive and engaging environment to get started with Python.
Students are requested to bring their own laptop computers if possible. If they cannot, a limited number of laptops will be available for student use during the course.
