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…

Wright, Lyniesha Chanell; Oliver-Hoyo, Maria Theresa – Chemistry Education Research and Practice, 2020
The mental models students have after engaging in an activity designed to teach infrared (IR) spectroscopy without reliance on IR absorption tables, were characterized. Qualitative analysis of semi-structured interviews, through open coding, allowed the classification of the mental models as Molecules as Dynamic (MAD), Bonds as Dynamic (BAD),…

Sendur, Gulten – Chemistry Education Research and Practice, 2020
In order for students to reach a level of meaningful understanding of chemistry, it is vital that they are able to form accurate relationships between different concepts. In particular, in organic chemistry, identifying intermolecular reactions, considering these reactions as a whole, and defining their results will make important contributions to…

Kotul'akova, Katarina – Chemistry Education Research and Practice, 2020
Today, science education demands preparation of scientifically literate people, emphasizing more the process of working with information than owning it. Such a task requires a deep understanding of pedagogical content knowledge by science teachers. This study focuses on revealing the beliefs of prospective chemistry teachers during their teaching…

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…

Schmidt-McCormack, Jennifer A.; Judge, Jessyca A.; Spahr, Kellie; Yang, Ellen; Pugh, Raymond; Karlin, Ashley; Sattar, Atia; Thompson, Barry C.; Gere, Anne Ruggles; Shultz, Ginger V. – Chemistry Education Research and Practice, 2019
Acid-base chemistry is a foundational topic that is taught in courses across the chemistry curriculum. Students often have difficulty distinguishing between the different theories of acid-base chemistry--Brønsted-Lowry and Lewis acid-base chemistry--and applying these two definitions correctly in unfamiliar scenarios. To help students learn these…

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…

Zohar, Asnat R.; Levy, Sharona T. – Chemistry Education Research and Practice, 2019
This work seeks to solve one of the basic problems in chemistry learning: understanding the chemical bond as a dynamic equilibrium between attractive and repulsive forces. This force-based model is difficult to grasp, as there are no analogues from everyday life for both attractions and repulsions happening simultaneously. In addition, current…

Sweeder, Ryan D.; Herrington, Deborah G.; VandenPlas, Jessica R. – Chemistry Education Research and Practice, 2019
Simulations have changed chemistry education by allowing students to visualize the motion and interaction of particles underlying important chemical processes. With kinetics, such visualizations can illustrate how particles interact to yield successful reactions and how changes in concentration and temperature impact the number and success of…

Shah, Lisa; Rodriguez, Christian A.; Bartoli, Monica; Rushton, Gregory T. – Chemistry Education Research and Practice, 2018
Instructional strategies that support meaningful student learning of complex chemical topics are an important aspect of improving chemistry education. Adequately assessing the success of these approaches can be supported with the use of aligned instruments with established psychometrics. Here, we report the implementation and assessment of one…

Emden, M.; Weber, K.; Sumfleth, e. – Chemistry Education Research and Practice, 2018
One of the most central tenets of chemistry education is developing an understanding of the processes that involve the Transformation of Matter. Current German curricula postulate content-related abilities ("Kompetenzen") that are expected to be achieved by secondary students when graduating from the lower secondary level at grade 10.…

Caspari, I.; Kranz, D.; Graulich, N. – Chemistry Education Research and Practice, 2018
Research in organic chemistry education has revealed that students often rely on rote memorization when learning mechanisms. Not much is known about student productive resources for causal reasoning. To investigate incipient stages of student causal reasoning about single mechanistic steps of organic reactions, we developed a theoretical framework…

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…

Turan-Oluk, N.; Ekmekci, G. – Chemistry Education Research and Practice, 2018
This study aims to conduct a detailed investigation on the effect the use of concept mapping, as an individual learning tool, has on students' success in learning the concept of gravimetric analysis. This study applies a case study research design to quantitatively examine the effect of the use of concept mapping and to conduct a detailed…

Joki, Jarkko; Aksela, Maija – Chemistry Education Research and Practice, 2018
Teaching chemical bonding using the octet rule as an explanatory principle is problematic in many ways. The aim of this case study is to understand the learning and teaching of chemical bonding using a research-informed teaching model in which chemical bonding is introduced as an electrostatic phenomenon. The study posed two main questions: (i)…
