This is a classroom lesson, repurposed for online "distance learning," and based in part of the following quotation:
"Word meaning is a phenomenon of verbal thought, or of the meaningful word. It is a unity of word and thought. No further evidence is needed to support this basic thesis. Our experimental studies have consistently supported and justified it. They have shown that by taking word meaning as a unit of verbal thinking we create the potential for investigating its development and explaining its most important characteristics at the various developmental stages. The primary result of this work, however, is not this thesis itself but a subsequent conclusion that constitutes the conceptual center of our investigation, that is, the finding that word meaning develops. The discovery that word meaning changes and develops is our new and fundamental contribution to the theory of thinking and speech. It is our major discovery, a discovery that has allowed us to overcome the postulate of constancy and unchangableness of word meaning which has provided the foundation for previous theories of thinking and speech."
