To understand and demonstrate Context-Free Grammar derivations and parse tree construction by exploring how strings are generated from grammars through interactive derivation processes. Students will learn to locate non-terminals in parse trees, identify matching production rules in CFGs for specific non-terminals, and carry out the substitution process by replacing non-terminals with appropriate subtrees. Through hands-on experimentation with different grammar examples including balanced parentheses, string generation patterns, and arithmetic expressions, students will gain practical experience in building parse trees step-by-step and understanding the fundamental relationship between formal grammars and the strings they generate.
