This essay attempts to distinguish and discuss the importance and limitations of different ways of being wrong. At first it is argued that strictly falsifiable knowledge is concerned with simple (instrumental) mistakes only, and thus is incapable of understanding more complex errors (and truths). In order to gain a deeper understanding of mistakes (and to understand a deeper kind of mistake), it is argued that communicative aspects have to be taken into account. This is done in the theory of communicative (...) action, which adds to our knowledge of errors the notion of communicative mistakes: mistakes as obstacles for sincere communication. However, to overcome this still purely negative judgement of errors, two processes are examined in which mistakes are best regarded as developmental steps, that is, steps not only meaningful in their own right (as containing some truth), but also as necessary preconditions for further progress. This would suggest that truth is born out of errors. But if so, one has to understand the wrongness of such errors; how is it that they are erroneous if they (somehow) contain the truth? At the end of this essay, a tentative answer to this question is given. (shrink)

Popper’s theory of learning is sometimes met with incredulity because Popper claims that there is no transference of knowledge or knowledge elements from outside the individual, neither from the physical environment nor from others. Instead, he claims that we can improve our present theories by discovering their inadequacies.The intent of this article is not to persuade educators to adopt Popper’s approach uncritically to build their professional knowledge. Rather, it presents a discussion on the need for teachers to adopt a critical (...) approach in eliminating what is inadequate and preserve what is adequate by modifying or abandoning whatever traditions or practices that are inadequate to improve their teaching practice. Popper claims that knowledge advances by searching for and eliminating error contained in our theory. In other words, we can improve our present theories by finding out their inadequacies. (shrink)

This essay takes—as its point of departure—Cavicchi’s (2006) argument that knowledge develops through experimentation, both in science and in educational settings. In attempting to support and extend her conclusions, which are drawn in part from the replication of some early tasks in the history of developmental psychology, the late realist-constructivist theory of Jean Piaget is presented and summarized. This is then turned back on the subjects of Cavicchi’s larger enquiry (education and science) to offer a firmer foundation for future debate. (...) Several of Piaget’s “forgotten works” are discussed; their theoretical contributions synthesized to form a single interdisciplinary, cross-pollinating narrative describing how it is that both children and scientists grow into the world. (In addition, translated excerpts from two related historical documents have been provided in an appendix, while detailed footnotes add further context and integrate the discussion with current advances in related fields.).
