It is argued in this paper that various approaches are available in designing teaching and learning experiences for technology education. However, many approaches are based on inappropriate assumptions about transfer, the ways in which meaning is represented by individuals and relationships among different kinds of experiences. It is advanced that the development of technology knowledge in school should aim at developing a rich inter-connectedness among the ways in which technological meanings can be understood by learners, so that learners experience transformations in relation to themselves, technological practice and their knowledge. Cultural-historical activity theory is suggested as a useful basis for designing instruction aimed at the various purposes of technology education.
