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.

The language used to talk about computers is uniquely colorful and sometimes extraordinarily difficult. This paper examines ‘computer discourse’ and points out its highly metaphorical nature. While the use of metaphor is unavoidable, it often leads, especially in informal settings, to the mannered use of words we call jargon. Metaphor becomes jargon when it is used too literally in a self-conscious manner. Experts often use their metaphors as though they were literally true. Technical details fall away and the metaphor is (...) taken for the reality it represents. The less expert sometimes mimic the language they hear, in a self-conscious manner, without truly understanding it. (shrink)

Nancy Leys Stepan’s historical analysis of the analogical reasoning used in nineteenth century research on human variation highlights an interesting feature of scientific discourse: metaphors imported from larger society can negatively impact scientific practice. In this paper, I consider the roles of analogical reasoning in scientific practice and demonstrate how it can mislead the scientists relying on it. One way, the problem of ingrained analogy, results when the correspondences of a metaphor become entrenched in the minds of scientists. Previous solutions, (...) offered by Turbayne (1971) and Recker (2004, 2010), lack the resources to address the problem. Thus, I propose introducing novel critique from relevant outsiders as a method to mitigate the power of scientific metaphors to mislead. (shrink)
