In this research, an educational approach to the concept of energy is proposed. It is based on the history of physics. In 1854 Hermann Hemlholtz gave a popular lecture on the recent discovery that energy is conserved. Such lecture is used as a guide to introduce the pupils within several nuances of this concept. Not much mathematics is used, so…

Students' perceptions of an activity involving visualization are important in assessing their learning of the task. In view of this, this study was developed with undergraduate students from different courses at a public Brazilian university. The research objective was to determine how three students, who are majoring in different courses…

The performance of any economy is based on scientific knowledge and technological innovation. Consequently, a highly motivated workforce with skills in science and engineering is key to any prosperous economy. Science education has a critical role in providing scientific literacy to students, as well as in training young people to choose careers…

The American Association for the Advancement of Science (AAAS) cites evolution as a core concept of biology, yet studies have found that biology students often exhibit low acceptance of evolution. As such, much of evolution education research aims to identify the causes of evolution rejection and develop instructional strategies to increase…

Thermodynamics education is not easy both for students and teachers. But the Entropy, Chemical potential, Real gas structure, Fugacity, Molecular interaction, Supercritical phenomena chapters become more comprehensible, if introduced via the pure real gases' cluster physics chapter. A pure gas consists of the only one type of basic particles,…

The content of organic chemistry is closely related to our everyday life, to nature, and to the human body. Illustrations play a big role in the acquisition of the course material, especially if those help to make the interpretation of the textual content easier. Hybrid illustrations are made up of combinations of realistic images (photographs,…

Students in high school tend to find genetics difficult to learn because it requires some crosslinked knowledge about subjects like genes, proteins, cells, tissues as well as organs and systems. It also becomes more difficult to connect and explain concepts such as the gene expression at the level of the cell to conceptualize the effect of the…

The use of approximations in solving problems in sciences can be vital for students. Order of magnitude estimation also helps with physical understanding of the quantities involved in a calculation. For example, in the first exam in a first-year class in chemistry the student must find the mass in grams of an atom; a couple of students will…

It could be argued that the main goal of the teaching process is to create accurate projections of scientific models in the minds of individuals. In this context, it could be argued that it is important to determine the change and development of the mental models that individuals create for events/phenomena and related metaphors in this process.…

This paper introduces two theoretical constructs, open-loop covariation and closed-loop covariation, that combine covariational reasoning and causality to characterize the way that three preservice mathematics teachers conceptualize a feedback loop relationship in a mathematical task related to climate change. The study's results suggest that the…

In case-based learning, students develop and apply course knowledge to solve tangible and "real life" problems. This practice can enhance student motivation and engagement in the analytical laboratory. In this application of case-based learning students analyze commercially available oils for CBD content. In the state of Texas anyone can…

The traditional learning method can be a challenging activity if the students are children with ADHD. There are studies that indicate that educational video games enhance the learning process in children. To objectively validate the aforementioned claim, this study aims to analyze and compare the brain waves activity of children with ADHD while…

A word association test was used to determine knowledge structures on biochemistry concepts of secondary school chemistry students, aged between 18-19 years. The basic biochemistry concepts related to the topic of Carbohydrates that take place in the International Baccalaureate Diploma Programme curriculum were determined as stimulus words:…

Interactive simulations allow students to independently explore scientific phenomena and ideally infer the underlying principles through their exploration. Effectively using such environments is challenging for many students and therefore, adaptive guidance has the potential to improve student learning. Providing effective support is, however,…

The primary objective of this research was to investigate the effects of model-based science instruction on the conceptual development of 7th grade students in the topic of electricity. This qualitative research was conducted during the 2022-2023 academic year, using purposive sampling method. The study comprised 33 7th grade students (18 boys and…
