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…

Tosun, Cemal – Chemistry Education Research and Practice, 2019
The aim of this study was to develop a Scientific Process Skills Test (SPST) in the context of ''Matter and its Nature''. It was investigated whether there was a predictive effect of demographical features and participating out-of-school learning opportunities across the 7th and 8th grade students' Scientific Process Skill (SPS) levels.…

van Vorst, Helena – Chemistry Education Research and Practice, 2018
This paper introduces Ladders of Learning (LLs) as a tool for structuring learning content and the teaching process in a transparent way for students. Learning material for a LL for Bohr's atomic model was developed by cooperation between chemistry teachers and university researchers and implemented in grade-eight chemistry classes. For evaluating…

Abels, Simone – Chemistry Education Research and Practice, 2016
Recent educational research emphasises the importance of analysing talk and gestures to come to an understanding about students' conceptual learning. Gestures are perceived as complex hand movements being equivalent to other language modes. They can convey experienceable as well as abstract concepts. As well as technical language, gestures…

Papageorgiou, George; Markos, Angelos; Zarkadis, Nikolaos – Chemistry Education Research and Practice, 2016
The current study aims to investigate students' representations of the atomic structure in a number of student cohorts with specific characteristics concerning age, grade, class curriculum and some individual differences, such as formal reasoning and field dependence/independence. Two specific task contexts, which were designed in accordance with…

Kapici, Hasan Özgür; Savasci-Açikalin, Funda – Chemistry Education Research and Practice, 2015
Textbooks are one of the primary teaching tools frequently used in schools and most teachers use them in their classrooms (Sanchez and Valcarcel, 1999). Since there are a lot of abstract concepts in science education, images in science textbooks play a vital role in the learning process (Kenan et al., 2011). Concretization of abstract concepts may…

Özalp, Dilek; Kahveci, Ajda – Chemistry Education Research and Practice, 2015
Student conceptions related with matter and the particulate nature of matter (PNM), are vital for advanced understanding in chemistry, and have been a research area of significant attention. Lacking in the literature are studies addressing chemical misconceptions from an ontological point of view. The purpose of the current study was to develop a…

Christian, Brittany N.; Yezierski, Ellen J. – Chemistry Education Research and Practice, 2012
Teachers tend to instruct topically, which requires the student to use multiple and interconnected concepts to succeed in each instructional unit. Therefore, it is beneficial to combine research on related concepts to form topic driven instruments to better assist teachers in assessing and instructing students. Chemical and physical change as a…

Bernholt, Sascha; Parchmann, Ilka – Chemistry Education Research and Practice, 2011
Current reforms in the education policy of various countries are intended to produce a paradigm shift in the educational system towards an outcome orientation. After implementing educational standards as normative objectives, the development of test procedures that adequately reflect these targets and standards is a central problem. This paper…

Liang, Jia-Chi; Chou, Chin-Cheng; Chiu, Mei-Hung – Chemistry Education Research and Practice, 2011
The nature and behavior of gas particles are essential concepts in teaching and learning of school chemistry. However, findings about students' understanding of gas particles--their composition, structure, and interactions involving movement and distribution--revealed that the difficulties students encounter in understanding gas particles vary…
