In practical work focussing on conceptual development, students spend valuable in-class time on collecting data rather than making sense out of it. This provides a barrier to learning about the targeted concept. To address this problem, we developed an approach that we coin collaborative data collection. Using a practical on the topic density, we describe this approach and illustrate how the focus of practical work shifts away from mere data-collection towards meaning making. Although a single practical is described, the approach can be applied to other practicals as well.@en

This article presents an experimental setup capable of conducting various experiments. The setup is used to accurately determine the acceleration due to gravity using either the pendulum or free fall experiment, as well as to allow students to conceive and conduct their own experiment. We discuss the design of the setup and the experiments conducted with it, highlighting the versatility and potential use for open inquiry. We include students’ perception on this particular experiment and how it led to an interesting and educational open inquiry.@en

This small-scale, qualitative study uses educational design research to explore how focusing on argumentation may contribute to students’ learning to engage in inquiry independently. Understanding inquiry as the construction of a scientifically cogent argument in support of a claim may encourage students to develop personal reasons for adhering to scientific criteria and to use these with understanding rather than by rote. An understanding of the characteristics of scientific evidence may clarify why doing inquiry in specific ways is important, in addition to the how. On the basis of five design principles—derived from literature—that integrate argumentation in inquiry and enhance learning through practical activities, we developed a teaching-learning sequence of five activities aimed at developing inquiry knowledge in lower secondary school students. By means of observations of a grade 9 physics class (N=23, aged 14–15), students’ answers to worksheets, and self-reflection questions, we explored whether the design principles resulted in the intended students’ actions and attitudes. We studied whether the activities stimulated students to engage in argumentation and to develop the targeted inquiry knowledge. The focus on argumentation, specifically through critical evaluation of the quality of evidence, persuaded students to evaluate whether what they thought, said, or claimed was “scientifically” justifiable and convincing. They gradually uncovered key characteristics of scientific evidence, understandings of what counts as convincing in science, and why. Rather than adopting and practicing the traditional inquiry skills, students in these activities developed a cognitive need and readiness for learning such skills. Of their own accord, they used their gained insights to make deliberate decisions about collecting reliable and valid data and substantiating the reliability of their claims. This study contributes to our understanding of how to enable students to successfully engage in inquiry by extending the theoretical framework for argumentation toward teaching inquiry and by developing a tested educational approach derived from it.@en

Physics inquiry can be interpreted as the construction of a cogent argument in which students apply inquiry knowledge and knowledge of physics to the systematic collection of relevant, valid, and reliable data, creating optimal scientific support for a conclusion that answers the research question. In learning how to devise, conduct and evaluate a rigorous physics inquiry, students should learn to choose and apply suitable techniques and adhere to scientific conventions that guarantee the collection of such data. However, they also need to acquire and apply an understanding of how to justify their choices and present an optimally convincing argument in support of their conclusion. In this modified and augmented Delphi study we present a view of inquiry knowledge and a way to assess it that acknowledges both of these components. Using our own expertise with teaching physics inquiry and using curriculum documents on physics inquiry, “inquiry knowledge” is deconstructed as a set of “understandings of evidence” (UOE)—insights and views that an experimental researcher relies on in constructing and evaluating scientific evidence. While insights cannot be observed directly, we argue that their presence can be inferred from a student’s actions and decisions in inquiry, inferred with more definitude as a more explicit and adequate justification is provided. This set of UOE is presented and validated as an adequate, coherent, partially overlapping set of learning goals for introductory inquiry learning. We specify conceivable types of actions and decisions expected in inquiry as descriptors of five attainment levels, providing an approach to assessing the presence and application of inquiry knowledge. The resulting construct, the assessment rubric for physics inquiry, is validated in this study. It distinguishes nineteen UOE divided over six phases of inquiry. Preliminary results suggesting a high degree of ecological validity are presented and evaluated. Several directions for future research are proposed.@en

Om de geringe leeropbrengst van practica te vergroten, ontwikkel en test ik in mijn promotieonderzoek een leerlijn onderzoeken. De activiteiten van deze leerlijn richten zich op het ontwikkelen van de benodigde kennis en kritische houding om een onderzoek succesvol uit te voeren. In dit artikel bespreek ik de eerste stap: leerlingen prikkelen om überhaupt een goed onderzoek op te wíllen zetten.@en

In 1999 stond in de NRC een column van Karel Knip over de vraag uit de wetenschapsquiz of je direct een wolkje melk in je koffie moet doen als de bel gaat of dat je dat beter kunt doen als je terugkomt van de buitendeur. De column geeft een mooi beeld van wat er allemaal kan komen kijken als je wat dieper op de vraag ingaat. Er blijken veel mogelijkheden te zijn om ook in de klas met deze vraag aan de slag te gaan!@en

When a new topic is introduced in the curriculum, teachers seek various ways to teach students the related concepts. For the novel topic 'materials' in the revised Dutch curriculum, I developed an experiment in which students determine Young's modulus using a guitar string. The experiment not only covers several concepts related to 'materials' it also provides a clear link to the physics of music and illustrates to students, aged 16, why the topic 'materials' could be of interest. @en

This paper explores students’ ability to analyse and interpret empirical data as inadequate data analysis skills and understandings may contribute to the renowned disappointing outcomes of practical work in secondary school physics. Selected competences, derived from a collection of leading curricula, are explored through interviews and practical tasks, each consisting of three probes. The 51 students, aged 15 and commencing post-compulsory science education in the Netherlands, were able to carry out basic skills such as collecting data and representing these. In interpreting the data in terms of the investigated phenomenon or situation however, performance was weak. Students often appeared to be unable to identify the crucial features of a given graph. Conclusions based on the data were often tautological or superficial, lacking salient features. Students failed to infer implications from the data, to interpret data at a higher level of abstraction, or to specify limitations to the validity of the analysis or conclusions. The findings imply that the students’ understanding of data-analysis should be developed further before they can engage successfully in more ‘open’ practical work. The study offers a collection of activities that may help to address the situation, suggesting a baseline for guided development of data analysis abilities.@en

Although learning about Nature of Science (NOS) promotes a variety of important outcomes, teachers often lack suitable activities for younger students to effectively address NOS. In this article I elaborate on a NOS activity developed for a teacher professionalisation workshop. The activity is suited for younger students as well, where clear links are made between elements of the activity and how science works. @en

Teaching a hands- and minds-on course, in which feedback is essential in order to learn, is difficult, especially in times of COVID-19 where student progression cannot be monitored directly. During the lockdown period, the workshops of an undergraduate Design Engineering course had to be transferred to the home situation, which required a redesign of this course by the staff. It also provided new opportunities for students to adapt to this situation, which required extra creativity and problem-solving skills. The adapted workshops revealed conditions that enhance maker education. However, providing timely feedback required a substantial amount of time not anticipated for. We also report that short instruction videos seem to work much better than longer lectures or tedious materials. As we practice what we preach, we will evaluate the course and apply our design knowledge acquired over the years.@en
