Ruby Programming for Beginners in Uganda

Course outline and learning expectations

This is a tutor-led course. The outline shows what your tutor will cover; teaching materials and examinations are provided directly to enrolled students.

What you will learn

• By the end of this beginner Ruby programming course, the learner will be able to:
• Explain what the Ruby programming language is and where it can be used in Uganda, East Africa and Africa.
• Install Ruby, use Interactive Ruby (IRB) and run Ruby programs from the command line.
• Write valid Ruby code using variables, constants, comments, operators and expressions.
• Work confidently with strings, numbers, booleans, `nil`, symbols, arrays, hashes and ranges.
• Accept user input and display clear program output.
• Use conditional statements and loops to solve practical problems.
• Organise reusable logic with methods, parameters, return values and variable scope.
• Process collections with common Ruby iterators such as `each`, `map`, `select` and `reduce`.
• Read from and write to local files using Ruby.
• Find and correct common syntax, runtime and logic errors.
• Build a complete command-line Ruby project for a practical African use case.
