Designing a computing course that leverages the strengths of both CS50 and W3Schools is an excellent idea. CS50 provides a strong foundation in computer science principles and problem-solving, while W3Schools is an invaluable, practical reference for web development languages.
Here is a proposed structure for a 4-level course, combining these resources to build a comprehensive curriculum.
CS50: Serves as the backbone for introducing core computer science concepts, like algorithmic thinking, data structures, and foundational programming in languages like C and Python. It teaches "how to think like a programmer."
W3Schools: Acts as the primary resource for practical, syntax-based learning, particularly for web development languages. It's the "how-to" manual for implementing what's learned in CS50.
Each level builds upon the previous one, with a natural progression from fundamental concepts to more specialized and practical applications. The time estimates are based on a learner dedicating approximately 5-10 hours per week, which is a reasonable pace for a self-guided or classroom environment.
Duration: 3-4 months
This level focuses on building a solid understanding of the fundamental building blocks of computer science. The goal is to demystify how computers work and introduce the core concepts of programming.
What to Teach:
CS50 (Weeks 0-3): Start with the introductory lectures of CS50. This covers topics like computational thinking, binary, algorithms, and data representation. The use of Scratch in CS50 is a great, low-barrier entry point to programming logic.
C Programming: Dive into the C language portion of CS50 (Weeks 1-4). This is crucial for understanding memory management, pointers, and how programs are executed at a lower level.
W3Schools: Introduce W3Schools as a supplementary resource for understanding the basics of HTML and CSS. Students can work through the W3Schools HTML and CSS tutorials in parallel with their C studies to get a feel for a different type of coding.
W3Schools HTML & CSS: A deep dive into the syntax and structure of HTML and CSS. This includes creating basic web pages, using tags, styling with CSS properties, and understanding the box model.
Key Projects/Assignments:
CS50 problem sets for C (e.g., cash, mario).
A simple personal webpage or resume page using W3Schools tutorials.
Duration: 3-4 months
This level transitions from low-level programming to more practical web development. Students learn a modern, high-level language and apply their foundational knowledge to build interactive web applications.
What to Teach:
CS50 (Weeks 5-8): Shift to the Python and web development sections of CS50. This introduces a more accessible language and shows how the same logical principles from C apply to Python.
W3Schools Python: Use W3Schools as the primary reference for Python syntax, data types, loops, and functions. This provides a clear, concise guide to the language.
JavaScript and the DOM: Introduce JavaScript for client-side interactivity. W3Schools is a perfect resource for this, covering everything from basic syntax to manipulating the Document Object Model (DOM).
CS50 (Week 8): The CS50 lecture on HTML, CSS, and JavaScript provides the theoretical context, while W3Schools provides the practical "how-to" guide.
Key Projects/Assignments:
CS50 problem sets for Python.
Build a simple web application with a front-end created with W3Schools-learned HTML/CSS/JavaScript and a back-end powered by Python. This could be a simple calculator, a to-do list, or a quiz.
Duration: 4-5 months
This level moves beyond basic applications to introduce more complex concepts required for building robust and dynamic systems. Students will learn about data persistence and how to use frameworks to streamline development.
What to Teach:
CS50 (Week 9): The SQL lecture from CS50 is an excellent introduction to relational databases and database design.
W3Schools SQL: Use W3Schools as a hands-on lab for practicing SQL queries (SELECT, INSERT, UPDATE, DELETE).
CS50's Web Programming with Python and JavaScript: This course is a natural progression from the main CS50 course and is heavily integrated with frameworks like Django. You can use this as a core part of the curriculum.
W3Schools: Continue using W3Schools as a reference for any web technology as needed, such as JSON or AJAX.
Frameworks: Introduce a back-end framework like Flask or Django (from CS50's Web Programming course) and a front-end framework like React (also covered in CS50's Web Programming).
Key Projects/Assignments:
Build a blog or a social media clone using a framework (like Django or Flask), with a database (SQL). This project would tie together all the concepts from Levels 1-3.
Duration: 2-3 months
The final level is dedicated to a major project that solidifies the student's knowledge and allows them to specialize in an area of interest. This is where they demonstrate their ability to apply all the concepts they've learned.
What to Teach:
CS50 Final Project: The capstone of the CS50 curriculum is the final project. This can be adapted for your course.
Independent Research and Problem-Solving: Students are encouraged to use all their resources, including W3Schools and other online documentation, to solve problems independently.
Specialized Topics: Based on the student's project, you can provide guidance on more advanced topics not covered in the core curriculum, such as security, APIs, or more complex data structures.
Key Projects/Assignments:
A significant, self-directed final project that solves a real-world problem. This could be a full-stack web application, a data analysis tool, or a mobile app prototype.
A final presentation where the student demonstrates their project and explains their technical decisions.
In April 2023, Trent Alexander-Arnold set up The After Academy, an initiative funded by Alexander-Arnold for the next five years that will support and aide former academy footballers. The After Academy is intended to provide training and career opportunities both in and out of football for footballers who did not make it past academy level and is being run with the co-operation of the PFA and Alexander-Arnold's sponsors, Red Bull, Under Armour and Therabody.[196]
