Energy consumption in the world is increasing more and more due to the huge energy request coming from emerging countries such as China, India, etc. To face the challenge of sustainability, a solution may be the use of solar energy, since it is the most abundant renewable energy source on Earth. The electromagnetic energy coming from the Sun can…

In this paper, the education system in Bosnia and Herzegovina is presented in the light of current state-level legislation, with an emphasis on chemistry education at the primary, secondary and tertiary level. The consequences of the last war in our country still persist and are visible in many aspects of everyday life, including the education…

Biology education should be relevant to young students so that they can become interested in biology and understand biological topics in their everyday and vocational lives. We conducted interviews and collected mind maps to examine Finnish pre-service biology teachers' (N = 16) views on the relevance of biology education. Furthermore, we analysed…

Learning the wave-particle dualism of electrons and photons plays a central role in understanding quantum physics. Teaching it requires that the teacher is fluent in using abstract and uncommon terms. We inspect the lexical structures of pre-service teachers' declarative knowledge about the wave-particle dualism of electrons and photons in the…

Teachers are confronted with many challenges in the science classroom. One of these challenges is finding a reliable learning approach to improve students' performance. This study used peer learning approach of teaching to help students learn and understand concepts in a photosynthesis class. The participants of the study were 40 science students…

Mathematics courses should prepare students to use mathematics in a range of contexts, including science. However, students often struggle in applying mathematics in physics courses, even when they understand the mathematical content (Rebello et al., 2007). Often the root of this struggle is attributed to the "student" or the…

Digital literacy is essential for scientific literacy in a digital world. Although the NGSS Practices include many activities that require digital literacy, most studies have examined digital literacy from a generic perspective rather than a curricular context. This study aimed to develop a self-report tool to measure elements of digital literacy…

The aim of this study was to analyse the kinds and frequency of visual learning representations within 8th grade students' notebooks for science classes. As part of the research, 93 science notebooks which belonged to students from 13 secondary schools in Kars Province (the east of Turkey) were collected at the end of the academic year in 2018.…

Among the basic aims of education, raising students as individuals that have the knowledge regarding the field as science literates and relate and reflect this knowledge to their daily life takes part. For this purpose, the curriculum and lessons should be given importance to daily life. At this point, in order for teachers to be able to include…

Polish universities offer a number of chemical competitions for high school students. One of oldest is the one organized by the Faculty of Chemistry of the Silesian University of Technology. For 27 years now this annual event has been an important tool for promoting the Faculty of Chemistry and admitting new students. It offers an opportunity to…

When student projects require an analytical step that is robust and sufficiently selective, high performance thin layer chromatography (HPTLC) is a method to be considered. However, for student laboratories not equipped for HPTLC, sample application as a sharp narrow band is a hurdle. The low eluting power of water on reversed phase plates can be…

For some time now, images in science have been an object of study in the history of science. The multiple roles that images play in scientific practice have been recognised and discussed. However, little attention has been given to science related images in educational contexts. The case of geology is all the more relevant because it is considered…

The photoelectric effect is one of the key experiments taught during first- or second-year university and high school modern physics courses. It is usually the first experiment to introduce light quantization and the concept of photons as "packets of energy." Here, we want to point out a widespread mistake concerning the interpretation…

While fungi play a vital role in Earth's ecosystems, they are not highlighted in the Next Generation Science Standards (NGSS). This article contains a unit plan to introduce students to the fungal kingdom, characteristics of fungi, and their role as decomposers. The unit plan is written in a 5E model format and can be adjusted for any type of…

The difficulties encountered by students in learning chemistry range from human factors to the intrinsic nature of chemistry. To enhance students' understanding of chemistry, there is a wide consensus within the community of chemistry educators on the importance of and need to integrate different levels of representations in chemistry teaching and…
