Pavlin, Jerneja; Glazar, Sasa A.; Slapnicar, Miha; Devetak, Iztok – Chemistry Education Research and Practice, 2019
The purpose of this paper is to explore and explain students' achievements in solving context-based gas exercises comprising the macroscopic and submicroscopic levels of chemical concepts. The influence of specific variables, such as interest in learning, formal-reasoning abilities, and visualisation abilities, is a significant factor that should…

Moreira, Patricia; Marzabal, Ainoa; Talanquer, Vicente – Chemistry Education Research and Practice, 2019
Understanding how chemistry teachers' interventions shape the reasoning that students express after a lesson is critical to support prospective and in-service teachers as they work with students' ideas in the classroom. In this qualitative research study, we analysed changes in the reasoning expressed by 10th grade students in a Chilean school in…

Lastusaari, Mika; Laakkonen, Eero; Murtonen, Mari – Chemistry Education Research and Practice, 2019
Changing majors or dropping out are of great concern to universities worldwide, but the role of learning approaches in terms of students' persistence has not been previously studied. Changing majors, especially in chemistry, is a severe problem in Finland. Here, learning approach data were collected with the ChemApproach questionnaire from 733…

Sreenivasulu, Bellam; Subramaniam, R. – Chemistry Education Research and Practice, 2019
We report here on an exploratory study done with a sample of university students (N = 140) which sought to explore their understanding of the term 'coordination number', a concept encountered in the topic of transition metals chemistry, through a simple open-ended question. The findings show that the conceptual space related to the conceptions…

Connor, Megan C.; Finkenstaedt-Quinn, Solaire A.; Shultz, Ginger V. – Chemistry Education Research and Practice, 2019
Promoting students' ability to engage in discipline-specific practices is a central goal of chemistry education. Yet if instruction is to meaningfully foster such ability, we must first understand students' reasoning during these practices. By characterizing constraints on chemistry students' reasoning, we can design instruction that targets this…

Boz, Yezdan; Ekiz-Kiran, Betul; Kutucu, Elif Selcan – Chemistry Education Research and Practice, 2019
In this study, we examined the effect of School Experience (SE) and Practice Teaching (PT) courses on pre-service chemistry teachers' beliefs towards chemistry teaching over a one-year period. To reach this purpose, participants' beliefs and experiences towards chemistry teaching were monitored closely throughout the varied phases of the two…

Bongers, Amanda; Northoff, Georg; Flynn, Alison B. – Chemistry Education Research and Practice, 2019
Creating and using models are essential skills in chemistry. Novices and experts alike rely on conceptual models to build their own personal mental models for predicting and explaining molecular processes. There is evidence that chemistry students lack rich mental models of the molecular level; their mental models of reaction mechanisms have often…

Ralph, Vanessa R.; Lewis, Scott E. – Chemistry Education Research and Practice, 2019
Students who score within the bottom quartile on cognitive measures of math aptitude have been identified as at-risk for low performance in chemistry courses, with less attention as to "why" such differential performance persists. At-risk students struggle most differentially on assessment items related to the mole concept and…

Ardura, Diego; Pérez-Bitrián, Alberto – Chemistry Education Research and Practice, 2019
The main goal of the present investigation was to analyze the effect of motivation towards physics & chemistry on achievement in secondary school students. We focused our interest on the comparison between students who chose the subject when becoming optional in the Spanish educational system and those who opted out. Our analyses uncovered the…

Chen, Ya-Chun; Wilson, Kimberley; Lin, Huann-shyang – Chemistry Education Research and Practice, 2019
Systems thinking has been an educational priority for more than a decade, yet its related assessment and teaching strategies have been understudied in the chemistry education research community. Through the lens of systems thinking, this study explores how undergraduate students connect and translate their conceptual representations when they are…

Dorfman, Bat-Shahar; Terrill, Bronwyn; Patterson, Kate; Yarden, Anat – Chemistry Education Research and Practice, 2019
Despite the advancements in the production and accessibility of videos and animations, a gap exists between their potential for science teaching and their actual use in the classroom. The aim of this study was to develop and evaluate an approach to boost chemistry and biology teachers' Technological Pedagogical Content Knowledge (TPACK) and their…

Nakiboglu, Canan; Nakiboglu, Nuri – Chemistry Education Research and Practice, 2019
In this study, how prospective chemistry teachers (PCTs) perceive precipitation and conceptualize precipitation reactions at the symbolic level was explored. Further, it was of interest to identify PCTs' visualization of the sub-microscopic level of precipitation reactions. The sample was drawn from the Chemistry Education Department at the…

Yesiloglu, Sevinç Nihal – Chemistry Education Research and Practice, 2019
The first purpose of this study was to introduce a laboratory modelling activity focusing on teaching the concepts of radioactive elements/atoms, radioactive decay, and half-life. The second was to investigate pre-service chemistry teachers' understanding of these concepts. Fifteen pre-service chemistry teachers who had enrolled in a Physical…

Hunter, Vichuda; Hawkins, Ian; Phelps, Amy J. – Chemistry Education Research and Practice, 2019
A laboratory is a large investment of time and money for departments of chemistry yet discussions continue about its purpose in the educational process. Helping students navigate the three levels of representation; macroscopic, particulate and symbolic is a potential use of this time. This study looked at two different types of visualization for…

Cole, Martin H.; Rosenthal, Deborah P.; Sanger, Michael J. – Chemistry Education Research and Practice, 2019
This paper describes two studies comparing students' explanations of an oxidation-reduction reaction after viewing the chemical demonstration and one of two different particulate-level computer animations. In the first study, the two animations differed primarily in the complexity of the visual images. Students viewing the more simplified…
