Avargil, Shirly; Saxena, Arunika – Research in Science Education, 2023
Drawing, constructing, and explaining a model of a given abstract phenomenon is a challenging task. In this study, students were engaged in the "Project-Based Inquiry Science (PBIS)-Air Quality" learning unit, as part of their chemistry curriculum. The study aim is to determine how well students understand chemistry conceptually after…

Gao, Yizhu; Zhai, Xiaoming; Cui, Ying; Xin, Tao; Bulut, Okan – Research in Science Education, 2022
This paper re-validates middle school students' learning progression of the concept of buoyancy (Gao et al., 2020) by using two-time point data. The previous study developed a four-level learning progression based on data collected at a single time point using cross-sectional design. This single-time-point model of learning progression calls for a…

Ðoric, Biljana; Lambic, Dragan; Jovanovic, Željko – Research in Science Education, 2021
The aim of this study was to determine the impact of three different software simulations for studying Ohm's law and connecting resistors on students' academic performance. A total of 168 eighth-grade pupils were divided into three groups. The first group used the software containing the simulation with an already created electrical circuit, an…

McHugh, Luisa; Kelly, Angela M.; Fisher, Jacqueline Horan; Burghardt, M. David – Research in Science Education, 2021
This study evaluated the effectiveness of the Mathematics Infusion into Science Project (MiSP), which integrated science and mathematics in an engaging middle school science curriculum that fostered improvements in science content knowledge, higher-level problem solving, and affective domains related to mathematics. The project design was based…

Gao, Yizhu; Zhai, Xiaoming; Andersson, Björn; Zeng, Pingfei; Xin, Tao – Research in Science Education, 2020
We applied latent class analysis and the rule space model to verify the cumulative characteristic of conceptual change by developing a learning progression for buoyancy. For this study, we first abstracted seven attributes of buoyancy and then developed a hypothesized learning progression for buoyancy. A 14-item buoyancy instrument was…

Metin, Duygu; Cakiroglu, Jale; Leblebicioglu, Gulsen – Research in Science Education, 2020
Practices such as astrology or crystal healing can be defined as pseudoscience. Against pseudoscience, one of the major responsibilities of science education must be to develop science-literate individuals who are able to understand what science is, how science is undertaken, how scientific knowledge is constructed, and how it is justified, then…

Opitz, S. T.; Neumann, K.; Bernholt, S.; Harms, U. – Research in Science Education, 2019
Energy is considered both as a disciplinary core idea and as a concept cutting across science disciplines. Most previous approaches studied progressing energy understanding in specific disciplinary contexts, while disregarding the relation of understanding across them. Hence, this study provides a systematic analysis of cross-disciplinary energy…
