Lev Vygotsky's research presented individual men tal processes as being determined by one's historically developed activity, both on a physical level (through labor) and on a mental level (through the use of psychological tools). In this study, the author reviews the translated research of Vygotsky and compares his use of the term psychological tools with research in the areas of metaphors and semiotics. Could these semiotic psychological tools be included in media sound bites and computer software to facilitate and enhance (...) learning? Because the author's research interests are in the area of instructional technology, the intention is to explore psychological theories, such as those of Vygotsky, to see how instructional technologists might use these theories. The ideal would be to incorporate theories into their design and create innovative technology programs that affect learning positively both in the United States and in other countries and cultures.
