Wang, Ya-Ling; Tsai, Chin-Chung – Research in Science Education, 2019
Students' conceptions of learning science and their relations with motive for learning may vary as the education level increases. This study aimed to compare the quantitative patterns in students' conceptions of learning science (COLS) and motives for learning science (MLS) across grade levels by adopting two survey instruments. A total of 768…

Salloum, Sara; BouJaoude, Saouma – Research in Science Education, 2019
The purpose of this research is to better understand the uses and potential of triadic dialogue (initiation-response-feedback) as a dominant discourse pattern in test-driven environments. We used a Bakhtinian dialogic perspective to analyze interactions among high-stakes tests and triadic dialogue. Specifically, the study investigated (a) the…

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…

Lee, Silvia Wen-Yu; Chang, Hsin-Yi; Wu, Hsin-Kai – Research in Science Education, 2017
The aim of this study was to examine the potential impact of the representational characteristics of models and students' educational levels on students' views of scientific models and modeling (VSMM). An online multimedia questionnaire was designed to address three major aspects of VSMM, namely the "nature of models," the "nature…

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…

Schroeder, Meadow; McKeough, Anne; Graham, Susan A.; Norris, Stephen P. – Research in Science & Technological Education, 2019
Background: Uncertainty is a crucial element of scientific knowledge growth. Students should have some understanding of how science knowledge is developed and why scientific conclusions are considered more or less certain than others. A component of the nature of science, it is considered an important aspect of science education and allows…
