Elements of Software Construction
MIT OpenCourseWare offers this introduction to core software development principles, covering how to identify and invent suitable abstractions for a problem. Lessons work through state machines, functional programming, and object-oriented programming as paradigms, along with design patterns that bridge the gap between models and code. Students study interfaces and specifications for achieving modularity, reasoning about code correctness using invariants, and testing techniques including test-case generation and coverage. The course includes exercises in modeling, design, implementation, and formal reasoning, giving learners hands-on practice with objects, functions, and abstract types.
