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,…

Students' recognition of the common procedural mistakes in the chemistry laboratory was examined in this study. Data were collected from 49 undergraduates studying Science Teaching. A video in which a student is purposefully making common procedural mistakes was shown to the students, and they were asked to recognize the mistakes. A Written…

The purpose of this study was to, first, examine the potential of lesson plans (LPs) of preservice science teachers (PSTs, N = 631) as a source for gathering rich data on their pedagogical content knowledge (PCK) and, second, qualitatively describe PSTs' reasons for the level of data richness in their LPs on PCK. PSTs' handwritten LPs were…

This study aims to investigate pre-service science teachers' knowledge levels, practical experiences, and perceived competencies in teaching biodiversity at secondary school level. The study was conducted in Turkey with 151 pre-service science teachers, 50 of whom were first-year, 34 second year, 42 third year, and 25 fourth year during the fall…

Biology, known as the science of life in its most general definition, is one of the branches of science closest to individuals due to the subjects it contains. Therefore, knowing the concepts related to biology correctly is important for the sustainability of the learning process. In this study, it was aimed to determine the conceptual perceptions…

The purpose of this study was to improve the pedagogical content knowledge (PCK) of pre-service chemistry teachers using a school experience course enriched with PCK development tools such as CoRe as a lesson planning form, observations of mentor teachers' teaching by using an observation form prepared based on PCK components, discussion sessions…

Didactic transposition theory examines the development from scientific/academic knowledge being produced by scientists to it becoming learned knowledge constructed by learners. According to the theory, four kinds of knowledge exist: scientific knowledge, knowledge to be taught, taught knowledge and learned knowledge. In this study, learning and…

The aim of this study is to determine Turkish pre-service science teachers' levels of chemical explanations of various daily life phenomena and to investigate whether these examples are in accordance with the high school chemistry curriculum in Turkey. This study was carried out with descriptive research methods. The participants are 71 freshmen…

Mole, molar mass and the Avogadro number are used constantly to measure the amount of substance in chemical changes. However, students have difficulty in understanding these concepts because they are not familiar with measuring very small amounts of matter that cannot be seen and weighed in daily life, like atoms. The mole concept was developed to…

In the research, it was aimed that children in the age group of 4-6 discover a different group of living things (fungi) living in addition to the plants and animals around them and to develop their awareness of living things. In addition, the study examined the effect of the activities prepared at the nature observation center on the cognitive and…

The aim of this study is to determine the students' misconceptions about the digestive system. In this quantitative research, the study group comprised totally 259 sixth-, seventh-, and eighth-grade students. The data were collected through a three-tier diagnostic test and analyzed in terms of scientific knowledge, the lucky guess, lack of…

One of the main courses that have been affected by instructional technology is science education since the nature of topics covered by the science curriculum may require the usage of technology to teach them better. The aim of the current study was to investigate the effects of virtual laboratories on the development of gifted children's…

In this study, it was aimed to determine high school students' cognitive structures regarding to the immunity, infection, allergy and autoimmunity. In this study, it was tried to reveal the cognitive structures of high school students on immunity, infection, allergy and autoimmunity just before COVID-19. The study was carried out with 77 students.…

In this study, the value of patriotism, which is one of the ten core values that students should acquire in the science course, was selected. In this context, the aim of the study is to reveal the views of pre-service science teachers on the teaching of patriotism and examine them in the context of value teaching. In this study, holistic…

The purpose of this study was to delve into the interaction between pre-service chemistry teachers' pedagogical content knowledge (PCK) and content knowledge (CK) while teaching electrochemistry. Two pre-service chemistry teachers enrolled in practice teaching course in chemistry education program participated in the study. All PCK components were…
