Multiple Languages

This curriculum gives students the opportunity to learn multiple programming languages within the same course, which is a relatively unique approach to programming instruction. Educators must be careful to ensure that students understand the connections between each of the programming languages, as they should not be presented as isolated concepts.

What makes it great:

By understanding that programming languages are different means to an end, students will be able to abstract out key programming concepts like loops, control structures, and variables and learn not to get caught up in the weeds of syntax.

Expert Take

CodeHS Computer Science Explorations 1 offers a thorough introduction to computer science, covering a broad spectrum of topics essential for beginners. The curriculum delves into fundamental programming concepts such as variables, loops, and conditionals and introduces nested structures very early in the course. The course transitions between JavaScript syntax in Units 1 and 2 to Python syntax in Unit 4, incorporating functions and parameters for a well-rounded but challenging programming experience. The course might pose challenges for teachers without prior programming experience, especially as the programming units progress swiftly. On the plus side, there are multiple videos and exercises to support student learning. Units 3 and 5 focus on non-programming CS concepts such as history, ethics, digital citizenship. This addition enriches the learning journey, offering students a more holistic understanding of computer science. A drawback is that this curriculum requires a paid subscription, though a free version is available with restricted functionality.
