Visible Parts, Invisible Whole : Swedish Technology Student Teachers’ Conceptions about Technological Systems

Technological systems are included as a component of national technology curricula and standards for primary and secondary education as well as corresponding teacher education around the world. Little is known, however, of how pupils, students, and teachers conceive of technological systems. In this article we report on a study investigating Swedish technology student teachers’ conceptions of technological systems. The following research question is posed: How do Swedish technology student teachers conceive of technological systems? Data was collected through in-depth qualitative surveys with 26 Swedish technology student teachers. The data was analysed using a hermeneutic method, aided by a theoretical synthesis of established system theories (system significants). The main results of the study are that the technology student teachers expressed diverse conceptions of technological systems, but that on average almost half of them provided answers that were considered as undefined. The parts of the systems that the students understood were mostly the visible parts, either components, devices, or products such as buttons, power lines, hydroelectric plants, or the interface with the software inside a mobile phone. However, the ‘invisible’ or abstract aspects of the technological systems, such as flows of information, energy or matter, or control operations were difficult to understand for the majority of the students. The flow of information was particularly challenging in this regard. The students could identify the input and often the output of the systems, that is, what systems or components do, but the processes that take place within the systems were elusive. Comparing between technological systems also proved difficult for many students. The role of humans was considered important but it was mostly humans as users not as actors on a more systemic level, for example, as system owners, innovators, or politicians. This study confirms previous research in that the students had a basic understanding of structure, input and output of a technological system. Thus, the adult students in this study did not seem to have better understanding of technological systems than school pupils and teachers in previous studies, although this is in line with previous investigations on the general system thinking capabilities of children and adults. The most important implication of this study is that students need to be trained in systems thinking, particularly regarding how components work and connect to each other, flows (especially of information), system dependency, and the human role in technological systems

The study of technology as a field of knowledge in general education : historical insights and methodological considerations from a Swedish case study, 1842–2010

Today, technology education in Sweden is both a high-status and a low-status phenomenon. Positive values such as economic growth, global competitiveness and the sustainability of the welfare state are often coupled with higher engineering education and sometimes even upper secondary education. Negative values, on the other hand, are often associated with primary and lower secondary education in this subject. Within the realm of technology education at such lower levels of schooling in Sweden, different actors have often called for reformed curricula or better teacher training, owing to the allegedly poor state of technology education in schools. Recurring demands for a change in technology education are nothing unique from an historical point of view, however. In fact, the urge to influence teaching and learning in technology is much older than the school subject itself. The aim of this article is to describe and analyse some key patterns in technology education in Swedish elementary and compulsory schools from 1842 to 2010. This study thus deals with how technological content has developed over time in these school forms as well as how different actors in and outside the school have dealt with the broader societal view of what is considered as important knowledge in technology as well as what kind of technology has particular significance. The long period of investigation from 1842 to 2010 as well as a double focus on technology as scattered educational content and a subject called Technology make it possible to identify recurring patterns, which we have divided into three overarching themes: Technological literacy and the democratic potential of technological knowledge, The relationship between school technology and higher forms of technology education and The relationship between technology and science.Skolan som arena för kunskapsbildning i teknik - samhällets behov och skolans möjlighete
