This paper will discuss the concepts of Bildung, subalternity, and physics- and engineering education and where these topics intersect and interact with one another. A central part of the concept of Bildung is educating citizens--active participators in society. At the same time, a central characteristic of subaltern groups is that their voices are not heard in society. If subaltern groups thus can be recruited into a Bildung-oriented education, their subalternness can over time be challenged, and the groups can be included as equals within society. In the study, 728 physics and bachelor engineering students are asked via a questionnaire about their motivation for their education choice to chart the potential for Bildung-oriented education within these fields. The responses are sorted through a thematic analysis. As this paper will show, the social background--class structure--differs significantly between physics- and bachelor engineering students, as do their motivations. These data along with documentation from previous research showing working-class students' predisposition toward STEM disciplines facilitate the possibility of sketching possible paths toward Bildung for these students that at the same time can lift subaltern groups and make their voices heard.
