This document discusses lecture, demonstration, and lecture-demonstration methods for teaching information and communication technology (ICT) topics. The lecture method involves a teacher-centered approach where the teacher explains content using examples, proofs, technology and aids while students passively listen. Demonstration involves the teacher showing students how to perform acts and then guiding students as they perform. Lecture-demonstration combines these methods by first explaining concepts through lecture then demonstrating performing parts of the topic. The document provides examples of using each method for different ICT topics and outlines advantages and limitations of each approach.
