This research is a systematic literature review study that aims to explore the evidence in publications that report on the types of misconceptions experienced by students in learning chemistry by providing types of students' chemical misconceptions based on levels and obtaining the correct formulation of misconceptions so that they can be used as…

The learners' conceptual understanding has become one of the leading research areas conducted by educational researchers. Both students and current educators should actively work to improve their understanding of alternative conceptions and deepen their conceptual knowledge. One of the essential concepts in chemistry learning is colligative…

This study focuses on examining senior high-school students' conceptual understanding and difficulties concerning electrochemistry and comparing patterns of thinking across Turkish and Indonesian contexts. The Electrochemistry Concept Questionnaire (ECQ) was applied to 516 Indonesian and 516 Turkish high school students right after the teaching of…

This study aims to examine pre-service science teachers' (PSTs') model-based (MB) content knowledge (CK) and knowledge of students' understanding (KSU) of chemical bonds. The participants of the study consist of 229 senior pre service science teachers. The study is a case study from qualitative research designs. The data of the study were…

In this study, it was aimed to examine the effects of inquiry-based activities supported by web 2.0 tools on the attitudes of students towards the chemistry lesson in the unit of 'Acids, Bases and Salts' in the 10th grade chemistry lesson. Considering the relevant achievements in the 2018 chemistry curriculum and using the web 2.0 tools Padlet and…

This study focuses on exploring pre-service science teachers' conceptual integration understandings in explaining the subject of metabolism with the concepts of physics and chemistry. Action research was employed in this study. Nine pre-service science teachers taking the General Biology II course participated. Participants were taught metabolism…

Thermodynamics is one of the most complex topics in chemistry. Cognitive Load Theory claims that the complexity of a subject is mainly due to element interactivity - how many elements an individual must organise simultaneously in her/his working memory to master a topic. The simultaneous processing of various chemistry and mathematics concepts to…

The purpose of this research was to determine the heuristics used by pre-service science teachers in understanding the details of hydrogen bonding. The reasoning processes demonstrated were evaluated based on ten heuristic models suggested by Talanquer (2014). Phenomenographic assessment of the 30 participants indicated that all ten heuristics…

This study investigates children's science learning in a nursery in Turkey. The participating children (aged 5 and 6) are from a socio-economically disadvantaged community. This is an ethnographic study that includes participant observations and audio recordings of classroom interactions based on a long-term basis. It takes a socio-cultural…

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…

Determining pre-service teachers' images and removing their misconceptions with scientifically true ones are very important so that these teachers could bring up students without misconceptions. In the current study, it was aimed to highlight pre-service science teachers' images and misconceptions about chemical equilibrium together and in detail.…

This research investigates the effect of the context-based approach (CBA) 'Relating-Experiencing-ApplyingCooperating- Transferring' (REACT) strategy supported with crossword puzzles on achieving the associate degree students in the chemistry laboratory course on the topic of acid-base titrations. A crossword puzzle game and four contexts related…

Introduction: Science courses involve a wide range of content. The benefits of science education become clear when science is applied to daily life because science has the capability of raising the quality of life by eliminating a variety of problems. Accordingly, as technological advances are made, daily life applications are frequently refreshed…

This study investigated the impact of peer review on developing pre-service science teachers' (PSTs) written arguments about socioscientific issues related to chemistry. In the study, a quasi-experimental design was used with experimental (32 PSTs) and comparison class (33 PSTs). The participants were PSTs who were juniors in a public university…

Being able to move between different representations levels (macroscopic, submicroscopic, and symbolic) is important to understand a chemical phenomenon meaningfully. The current study investigated how pre-service science teachers moved from symbolic representation to sub-microscopic representation. A total of 205 pre-service science teachers,…
