Interested candidates can find these courses online at the official website of Harvard University for ‘Professional and Lifelong Learning’ – pll.harvard.edu.
CS50: Introduction to Computer Science
This introductory course, CS50x, provides deep insight into the intellectual enterprises of computer science and programming. Professor David J. The course, taught by Malan, covers a wide range of topics including algorithms, data structures, security and software engineering using languages such as C, Python, SQL, JavaScript, HTML and CSS. Problem sets are inspired by real-world domains such as biology, cryptography, and gaming. Whether you have prior programming experience or not, this course will teach you to think algorithmically and solve problems efficiently.
CS50 Introduction to Programming with Scratch
If you’re new to programming, this course is a great starting point. You’ll learn programming through Scratch, a visual programming language that uses graphical blocks to represent code. You’ll cover key programming concepts like functions, loops, variables, and conditions. This course lays the foundation for further learning in programming.
CS50 Web Programming with Python and JavaScript
This course dives deep into web programming, focusing on database design, scalability, security, and user experience. You’ll learn to write and use APIs, create interactive user interfaces, and take advantage of cloud services like GitHub and Heroku. By the end of the course, you will be equipped with the skills to design and deploy applications on the web.
CS50’s Introduction to Cyber Security
Designed for both technical and non-technical learners, this course provides an introduction to cyber security. You will learn how to protect your data, devices, and systems from existing threats, and understand the trade-offs between security, usability, and risk. The course includes real-world examples of cyber threats, giving you the knowledge to recognize and evaluate potential security risks both at home and in the workplace.
CS50’s Introduction to Databases with SQL
In this course, you will explore databases and SQL (Structured Query Language). You’ll learn how to create, manage, and query relational databases, as well as how to model real-world data using tables, keys, and constraints. The course also covers techniques such as data normalization, using views, and optimizing queries with indexes, making it a solid foundation for anyone interested in working with databases.
Data Science: Machine Learning
Part of the Professional Certificate Program in Data Science, this course introduces you to the field of machine learning. You’ll learn about training algorithms using data to build predictive models, including popular techniques like principal component analysis, regularization, and cross-validation. The course includes building a movie recommendation system, which helps you gain practical experience with machine learning algorithms and data analysis.
