Hennah, Naomi – Chemistry Education Research and Practice, 2019
The present paper reports upon the design and implementation of a novel practical work pedagogy that is shown to increase students' retention of practical procedures. The chemistry exams, for 15 to 16-year olds in England, will be assessed entirely through terminal examination questions from 2018. Longer term retention of learning is critical if…

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…

Ye, Jianqiang; Lu, Shanshan; Bi, Hualin – Chemistry Education Research and Practice, 2019
This study uses graphs of conductivity measured by a microcomputer-based laboratory (MBL) to promote students' macro, micro, and symbolic representations when learning about net ionic reactions (NIR). A total of 54 students, aged 14-15 years old participated in this research, and were randomly divided into an experimental group (N = 27) and a…

Lu, Shanshan; Bi, Hualin; Liu, Xiufeng – Chemistry Education Research and Practice, 2019
Students have various conceptions of electrolytes in learning chemistry. The aim of this study is to identify 10th grade students' understanding of the electrolyte concept by using a phenomenographic method. Eight students, whose abilities were at different levels, were selected and interviewed. The findings show that four distinctive categories…

Teke, Dilek; Sozbilir, Mustafa – Chemistry Education Research and Practice, 2019
This study aimed to identify the needs of a 10th grade congenitally blind student in an inclusive chemistry classroom and design and develop tactile materials to teach the 'energy in living systems' topic with particular emphasis on covering the symbolic language of the chemistry. A single case study design was used to carry out an in-depth and…

Wei, Bing; Liu, Hao – Chemistry Education Research and Practice, 2018
We have examined an experienced chemistry teacher's pedagogical content knowledge (PCK) of teaching with practical work in China. Based on the well-known PCK model by Magnusson S. J., Krajcik J. and Borko H., (1999), "Nature, sources, and development of pedagogical content knowledge for science teaching," in Gess-Newsome J. and Lederman…

Basso, A.; Chiorri, C.; Bracco, F.; Carnasciali, M. M.; Alloisio, M.; Grotti, M. – Chemistry Education Research and Practice, 2018
Improving the interest of high-school students towards chemistry (and science in general) is one of the goals of the Italian Ministry of Education. To this aim, we designed a context-based activity that actively involved students in six different laboratory experiences interconnected by a case study of the murder of Miss Scarlet, from the famous…

Kousa, P.; Kavonius, R.; Aksela, M. – Chemistry Education Research and Practice, 2018
The aims of this study were to determine low-achieving students' attitudes towards chemistry and how the attitudes differ within a low achieving group. The most preferred teaching methods were also defined. Empirical data (n = 2949) were collected by stratified sampling from fifteen-year-old Finnish lower-secondary school students as part of a…

Cheng, Maurice M. W. – Chemistry Education Research and Practice, 2018
This paper reports on an interview study of 18 Grade 10-12 students' model-based reasoning of a chemical reaction: the reaction of magnesium and oxygen at the submicro level. It has been proposed that chemical reactions can be conceptualised using two models: (i) the "particle model," in which a reaction is regarded as the simple…
