Gkitzia, Vasiliki; Salta, Katerina; Tzougraki, Chryssa – Chemistry Education Research and Practice, 2020
Meaningful understanding of chemistry, among others, includes the ability of an individual to think simultaneously at macroscopic, submicroscopic and symbolic levels, and this presupposes the competence to translate between different types of chemical representations. In this study, we investigated 11th grade Greek students' and 3rd year…

Lu, Huanhuan; Jiang, Yanxia; Bi, Hualin – Chemistry Education Research and Practice, 2020
The galvanic cell is a basic concept in electrochemistry. To assess mainland Chinese students' proficiency levels in galvanic cells, the Galvanic Cell Proficiency Level Assessment (GCPA) was developed based on the Rasch model. The GCPA was developed through a pilot test and consists of seven multiple-choice questions and four open questions. The…

de Waard, Esther F.; Prins, Gjalt T.; van Joolingen, Wouter R. – Chemistry Education Research and Practice, 2020
Sustainability has become a prominent theme in society and can be considered as an integral part of scientific citizenship. This study investigates to what extent the production, use and re-use of (bio)plastics initiates students' reasoning and to identify the kind of content knowledge students put forward. The structure of students' arguments was…

Vogelzang, Johannes; Admiraal, Wilfried F.; van Driel, Jan H. – Chemistry Education Research and Practice, 2020
Secondary science education plays a key role in students' process to become scientifically literate citizens. However, teaching students to acquire the necessary skills and knowledge to deal with complex societal issues is challenging. This paper reports about a study in which Scrum -- a methodology to manage complex projects -- was implemented in…

Eymur, Guluzar – Chemistry Education Research and Practice, 2019
The aim of the present study was to investigate the influence of the explicit nature of science instruction embedded in the Argument-Driven Inquiry method compared with an implicit inquiry method on eleventh grade students' conceptions of NOS. The study used a pre-/post-test control group design to investigate the influence of the explicit nature…

Akin, Fatma Nur; Uzuntiryaki-Kondakci, Esen – Chemistry Education Research and Practice, 2018
We examined the interactions among pedagogical content knowledge (PCK) components of novice and experienced chemistry teachers in teaching reaction rate and chemical equilibrium topics in this qualitative multiple-case design study. For this aim, three chemistry teachers who had different levels of teaching experience in chemistry teaching were…

Yaseen, Zeynep – Chemistry Education Research and Practice, 2018
This research investigates the use of student-generated animations in the teaching and learning of chemistry. Previous research has identified the potential for animations to contribute to student learning in science. In particular, animations have the capacity to represent the dynamic process and motions that may be inherent in some chemical…

Gegios, Theodoros; Salta, Katerina; Koinis, Spyros – Chemistry Education Research and Practice, 2017
In this study we present an analysis of how the structure and content of the Greek school textbook approaches the concepts of chemical kinetics, and an investigation of the difficulties that 11th grade Greek students face regarding these concepts. Based on the structure and content of the Greek textbook, a tool was developed and applied to…

Vlacholia, Maria; Vosniadou, Stella; Roussos, Petros; Salta, Katerina; Kazi, Smaragda; Sigalas, Michael; Tzougraki, Chryssa – Chemistry Education Research and Practice, 2017
We present two studies that investigated the adoption of visual/spatial and analytic strategies by individuals at different levels of expertise in the area of organic chemistry, using the Visual Analytic Chemistry Task (VACT). The VACT allows the direct detection of analytic strategy use without drawing inferences about underlying mental…

Derman, Aysegul; Eilks, Ingo – Chemistry Education Research and Practice, 2016
Understanding students' cognitive structures in a specific knowledge domain helps to determine the ''what, how and why'' features of such knowledge, so that we can take these structures into consideration in teaching. The purpose of the present study was to identify students' cognitive structures about solution and dissolution concepts. The study…

Akaygun, Sevil – Chemistry Education Research and Practice, 2016
Visualizing the chemical structure and dynamics of particles has been challenging for many students; therefore, various visualizations and tools have been used in chemistry education. For science educators, it has been important to understand how students visualize and represent particular phenomena--i.e., their mental models-- to design more…
