Düsing, Katharina; Asshoff, Roman; Hammann, Marcus – Journal of Biological Education, 2019
This study investigates students' conceptions of the carbon cycle with regard to the components they believe to be relevant to the carbon cycle, how they interrelate these components, the ways in which they trace carbon atoms, and the different levels of biological organisation they consider when doing so. A total of 142 students aged 13-16 years…

Rusek, Martin; Vojír, Karel – Chemistry Education Research and Practice, 2019
This paper focuses on the procedure and results for analyzing text-difficulty in lower-secondary chemistry textbooks in the Czech Republic. The authors use established methodology for text-difficulty analysis by Nestler, adapted by Prucha and Pluskal by adding a second independent analyser to improve reliability. Some textbooks do not follow the…

Kok, Karel; Priemer, Burkhard; Musold, Wiebke; Masnick, Amy – Physical Review Physics Education Research, 2019
In this study with 153 middle school students, we investigate the influence of the number of decimal places from the reading of a measurement device on students' decisions to change or keep an initial hypothesis about falling objects. Participants were divided into three groups, introduced to two experiments--the time it takes a free falling…

Yoon, Susan A.; Goh, Sao-Ee; Yang, Zhitong – Complicity: An International Journal of Complexity and Education, 2019
Recent research on what students know about complex systems shows that they typically have challenges in understanding particular system ideas such as nonlinearity, complex causality, and decentralized control. Yet this research has yet to adopt a systematic approach to learning about complex systems in an ordered way in line with the Next…

Hild, Pitt; Gut, Christoph; Brückmann, Maja – Research in Science & Technological Education, 2019
Background: Several different measures have been proposed to solve persistent validity problems, such as high task-sampling variability, in the assessment of students' expertise in 'doing science'. Such measures include working with a-priori progression models, using standardised item shells and rating manuals, augmenting the number of tasks per…

The current scales for self-blame are not suitable for school bullying scenarios and most lack validity. This study used a self-developed scale to measure bullied victims' tendency to self-blame and further examined whether victims and bully/victims exhibited different tendencies toward self-blame under both bullied and generalized scenarios. The…
