Exploring the role of generative AI in science teacher education programs
A qualitative study
Integrating argumentation in physics inquiry
A design and evaluation study
Secondary school students often only use the rules for doing scientific inquiry when prompted, as if they fail to see the point of doing so. This qualitative design study explores conditions to address this problem in school science inquiry. Dutch students (N = 22, aged 14–15) repeatedly consider the quality of their work: in a conventional, guided inquiry approach; by evaluating their conclusion in terms of the contextual purpose of the investigation; as consumers of knowledge facing the (hypothetical) risk of applying the findings in the real world. By gauging students’ confidence in the inquiry’s trustworthiness, we established that, while each confrontation instigated some students to (re)consider the quality of their inquiry, the final stage had the greatest impact. Students came to see that finding trustworthy results is essential, requiring scientific standards. The scientific quality of their inquiries was described, weaknesses identified and compared with the improvements students themselves proposed for their inquiries. While the improvemens were expressed in non-specific terms these align with a scientific perspective. Students now wanted to find trustworthy answers by exploiting scientific standards. In enabling students to engage successfully in basic scientific inquiry, finding ways to establish students’ mental readiness for attending to the quality of their scientific claims, and of personalised scientific criteria for their assessment, is indispensable.
Defining and assessing understandings of evidence with the assessment rubric for physics inquiry
Towards integration of argumentation and inquiry
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.
