This document discusses how multimedia and speech can enhance learning and the development of thinking skills in primary school students. It argues that students learn best when they are encouraged to use spoken language to express their thinking, rather than being expected to rely primarily on writing. Using tools like AudioTouch, Tux Paint, and Voicethread allows students to discuss and explain their ideas out loud, which helps clarify and solidify their understanding. The document provides examples of how students themselves reported learning more effectively about topics like global warming when they were able to draw pictures, record explanations with microphones, and discuss concepts with others.
