There is substantial evidence that students have difficulty applying and prioritizing the two basic principles of mass conservation (i.e., the continuity equation) and energy conservation (i.e., Bernoulli’s equation). When distracted by questions which involve gravity students based their answers on ill-supported assumptions about local pressures. The predominant arguments use a simplified Bernoulli equation, descriptive arguments or analogies to single-particle motion. Based on these results, an instructional intervention is developed that seems to address the observed difficulties.

About 250 undergraduate engineering students were given a test consisting of two hydrodynamics questions, combining multiple-choice format with subsequent open-ended explanations. There is substantial evidence that students have difficulty applying and prioritizing the two basic principles of mass conservation (expressed in the continuity equation) and energy conservation (i.e., Bernoulli’s equation). When faced with questions that involve gravity, dissipative effects (“friction”), or a visible pressure drop, a considerable number of students did not invoke the continuity equation in situations where applying it is a necessary step for arriving at the correct answer. Instead, even after lecture instruction on this topic, many of the first-year students based their answers on ill-supported assumptions about local pressures. Some of them used formal arguments from a simplified Bernoulli equation (“lower pressure means higher velocity”), while others based their answer on intuitive arguments (“higher pressure leads to higher velocity”). We also found reasoning based on analogies to single-particle motion (“flow velocity decreases when flowing upwards or friction is present”). Contrary to other researchers, we did not see any evidence for the hypothesis that students think of water as a compressible fluid. Instead, students’ answers often indicate a lack of understanding of the conservation of mass or its implications for incompressible fluids or of the role that this principle plays in the context of fluid flow. In addition, our data indicate that some students have more general difficulties in describing and reasoning about technical situations, such as applying equations containing multiple variables, distinguishing spatial differences in a quantity from its changes with respect to time, or realizing the meaning of idealizations. We also present some evidence that different levels of activation of students during instruction influence the prevalence of these difficulties and discuss some implications for instruction.

There is evidence that instructional materials that take into account such difficulties and prompt students to critically assess their own understanding can improve student learning. In this paper Tutorials in Introductory Physics are introduced, a set of materials intended to supplement the lecture, textbook, and laboratory of standard introductory physics courses for students in physics, engineering, and other fields. The Tutorials in Introductory Physics were originally developed by Lillian McDermott and the Physics Education Group at the University of Washington. They have been translated into other languages, including Spanish, Greek and German. In addition, they have served (and continue to serve) as a model for the development of instructional materials for other STEM subjects, such as electric circuits and engineering mechanics. We discuss various aspects of incorporating the Tutorials into a typical course and possible issues associated with their implementation.

Dass das Verstehen komplexer Inhalte wie in der Physik nur durch die aktive eigene Auseinandersetzung mit dem Stoff gelingen kann, ist weitgehend anerkannt. Als besonders wirksam erweist sich diese Auseinandersetzung, wenn Studierende in kleinen Gruppen arbeiten und gezielt vorbereitete Tutor:innen ihre Aufmerksamkeit auf kritische Punkte lenken. Forschungsbasierte und auf ihre Wirksamkeit überprüfte Lehrmaterialien, die diese kritischen Punkte thematisieren – Tutorials –, stehen für den Hochschulbereich zur Verfügung. Versetzen Sie sich gedanklich in die Rolle der Lehrperson in einer Physiklehrveranstaltung – sei es in einer Vorlesung oder einer Übung: Welche Aufgabe haben Sie? Was muss geschehen, damit die Studierenden ein Verständnis physikalischer Gesetzmäßigkeiten erwerben? Halten Sie möglichst ein paar Gedanken schriftlich fest. Vielleicht haben Sie notiert, dass Sie die Physik besonders gut, motivierend und anschaulich erklären oder mit klaren Herleitungen und auch beeindruckenden Experimenten das Thema darstellen möchten. Diese Aspekte sind zweifellos wichtig, aber reichen möglicherweise nicht aus. Reflektieren Sie Ihre eigene Lernerfahrung: Wann haben Sie selbst ein physikalisches Konzept verstanden und konnten es auch auf eine zuvor noch nicht betrachtete Situation korrekt anwenden? Vermutlich dann, wenn Sie sich aktiv und konstruktiv mit dem Stoff auseinandergesetzt haben. Vielleicht haben Sie auch mit anderen diskutiert und Ihre Argumente systematisch miteinander abgeglichen. Für das Erlernen von Physik (und anderen MINT-Fächern) ist es hilfreich, Studierenden möglichst viele solcher Lerngelegenheiten zu bieten [1, 2]. Methoden hierfür sind etwa Peer Instruction oder Just-in-Time-Teaching [3, 4].
