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,…

The rapid development and impact of nanoscience and nanotechnology (NSNT) on economy has led policy makers and educators to focus on nanotechnology education. The two main views concerning appropriate level to teach nanoscience and nanotechnology (NSNT): The first favors teaching in higher education; the second recommends familiarizing and…

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…

Chemistry as a discipline in general incorporates abstract concepts, which should be visualized through experiment- and application-oriented methods. It is a well-known fact in Turkey that chemistry class offered by simple and traditional methods cannot be understood by students at a satisfactory level. Such chemical subjects as atoms, molecules,…

This study was conducted to determine the differences in the conceptual understanding of 52 Turkish students who were taught with a scientific argumentation approach in grade 12 chemistry. The concept test was administered to the participants as a pre-test and post-test, and it contained two questions. The first had two sub-questions had two…

The present investigation aims to analyze the knowledge levels and chemical representation levels of pre-service primary school teachers (PPSTs) on the experiment of distillation. For this purpose, the cross-sectional survey technique, one of the quantitative research designs was employed. The study was carried out at a Faculty of Education in the…

The aim of this study is to examine the effects of computer-based analogy (CBA) used in science teaching in terms of the unit of Structure and Properties of Matter on seventh-grade students' academic success. The attitudes of students against science teaching lesson were also described in this study. This study was applied to 60 seventh-grade…

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…

The aim of this study was to investigate the visual images of pre-service teachers who take biology courses in undergraduate education about biology by analyzing their drawings. The research was conducted with 97 pre-service teachers, studying at the education faculty of a university in Turkey and taking biology course during undergraduate…

In this study with high school students, a descriptive scanning model, one of the qualitative research methods, was used to determine the extent to which the achievements of the hybridization occurred. The study was conducted with 12th grade students studying in a public high school in Bursa in 2017-2018 academic year. According to the findings…

The purpose of the study is to determine the knowledge and awareness of gifted children receiving education in the Science and Art Center on nanotechnology. The descriptive survey model was used in the study. The purposeful sampling method was chosen and a total of 160 students receiving education in two Science and Art Centers located in the city…

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…

The hybridization of carbon is an important problem of quantum chemistry. It means that atomic orbitals could mix giving hybrid orbitals. Orbitals are not physical objects; they are mathematical solutions of the Schrodinger equation. The aim of this study is to determine through phenomenographic method how Science Teaching undergraduate students…

Misconceptions are the number one factor leading students to failure when studying physics. To teach physics effectively, misconceptions must be spotted and overcome. Conceptual change texts are of great use in identifying and dealing with fallacies. Such texts can help physics teachers diagnose student misconceptions and the reasons for these,…

The use of concept mapping as a tool to measure the meaningful learning of students is the focus of this study. The study was carried out with 24 last year students (22 years old) from the Department of Chemistry Teaching at Fatih Faculty of Education, Karadeniz Technical University (KTU). Prospective Chemistry Teachers (PCT) were asked to create…
