Constructivism, find and replace, teaching, coding, color inversion.

The paper aims to outline the ways to replace the classic transmissive approach to instruction of basic user?s computer skills with the elements of constructivism. On the example of working in a text editor, the authors demonstrate how the ?Find and Replace? tool can be suggestively and purposefully used in instruction. The analysis of the usability and possible errors of these tools enables the formulation of tasks suitable for constructivist instruction. For illustration, we present two examples of problematic tasks ? inversion of black-and-white image and text coding. The problematic tasks were solved by students, future lower primary school teachers. The paper presents the experience acquired from the constructivist-based instruction.
