'A lack of prior knowledge in the other discipline' is often given by geoscience instructors to explain why students struggle to apply knowledge from other disciplines to the Earth. We examine this assumption by considering the disciplinary crossing of buoyancy (physics) to isostasy (geoscience). We investigate the teachers' perspective through…

The aim of the present study is to explore on the alternative conceptions of impetus theory and projectile motion of students with high functioning autism spectrum disorders and compare them with those of typical development. For this purpose, an experimental investigation was conducted with 19 students with high-functioning autism (age range:…

Presenting novel numbers about climate change to people after they estimate those numbers can shift their attitudes and scientific conceptions. Prior research suggests that such science learning can be supported by encouraging learners to make use of given benchmark information, however there are several other numerical estimation skills that may…

This longitudinal case study explores how students' epistemic uncertainty in argumentation can be adapted as a resource to develop knowledge in a fifth-grade classroom. Major data sources include 12 videotaped whole-class discussions focused on group presentation of arguments to obtain peers' critiques across two course units, the ecosystem and…

Designing and conducting sound and informative experiments is an important aspect of inquiry learning. Students, however, often design experiments that do not allow them to reach conclusions. Considering the difficulties students experience with the process of designing experiments, additional guidance in the form of an Experiment Design Tool…

The present study investigated the influence of two factors, namely, argumentation approach and students' prior knowledge on the learning of scientific concept and argumentation in descriptive and theoretical scientific concept-based topics. Four 7th grade science classes totalling 138 students participated and were assigned to four groups…

When learning with abstract and scientific multiple external representations (MERs), low prior knowledge learners are said to have difficulties in using these MERs to achieve conceptual understanding. Yet little is known about what these limitations precisely entail. In order to understand this, we presented 101 learners with low prior knowledge…

Comics are popular with adolescents because of their features of humor, narrative, and visual imagery. The purposes of this study were to examine the learning outcomes and emotional perceptions of reading a science comic book and a science text booklet for students of different levels of achievement, and to explore the main factors of the two…

This study investigated the effects of students' prior science knowledge and online learning approaches (social and individual) on their learning with regard to three topics: science concepts, inquiry, and argumentation. Two science teachers and 118 students from 4 eighth-grade science classes were invited to participate in this research. Students…

Quantitative and qualitative studies of various aspects of the perception of biotechnology were conducted among 469 Slovenian high school students of average age 17 years. Our research aimed to explore relationships among students' pre-knowledge of molecular and human genetics, and their attitudes to four specific biotechnological applications.…

Inquiry learning environments increasingly incorporate modelling facilities for students to articulate their research hypotheses and (acquired) domain knowledge. This study compared performance success and scientific reasoning of university students with high prior knowledge (n = 11), students from senior high-school (n = 10), and junior…

This paper deals with the features and design of explanations in public physics lectures. It presents the findings from a comparative study of three exemplary public physics lectures, given by practicing physicists who are acknowledged as excellent public lecturers. The study uses three different perspectives: the lecture, the lecturer, and the…

Studies of the relationship between students' propositional knowledge (as measured by concept mapping tasks) and their study strategies (as measured by self-report questionnaires) for electricity in first-year university courses are described. The effect of propositional knowledge and prior knowledge on both conceptual knowledge and study…

Reports on the relationship between students' propositional knowledge, measured by concept mapping tasks, and their study strategies, measured by self-report questionnaires, as it relates to the concept of photosynthesis as presented in a first-year biology course. Results indicate that involved, purposeful study strategies, prompted by relevant…
