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,…

When the COVID-19 pandemic forced school closures, science, technology, engineering, and mathematics (STEM) teachers were left with the challenging task of devising ways for students to conduct experiments at home. This was necessary because experiments and other hands-on activities are integral to STEM education and are linked to the development…

The scope of this preliminary study revolves around investigating the effectiveness of experiential learning in upper-year science laboratory courses in a post-pandemic era. In this study we have explored two key questions: 1. Can experiential learning facilitate independent inquiry in an upper-year undergraduate laboratory in a post-pandemic era?…

In a chemistry course for students not majoring in science, there is more to learn than some memorized facts: the student can find, in most non-major chemistry texts, the definition of atomic number, something about chemical bonding, and names of some classes of chemical compounds. Where facts come from and how accurately they are known are often…

The switch to online learning required a creative solution to allow for the experiential learning outcomes of the program to be satisfied when access to physical spaces and equipment was restricted. This paper describes a collaborative process between technical and support staff as well as research and teaching faculty that led to the creation of…

Science and technology education necessitates teaching and learning experiments involving electronic circuit construction and measurements using experimental equipment. In this study, a novel cross reality system for learning physical circuit construction and performing virtual experiments using virtual experimental equipment with mid-air haptics…

Testing the reproducibility of an experiment is considered a good practice in science, and the possibility to reproduce an experiment is a condition of its scientificity. We investigate the ability of children to consider a counterintuitive phenomenon as reproducible. The study involved 62 5-year-old children from 4 classes. They were presented…

Brazil is a country that does not invest enough in basic education, thus leaving a gap in the knowledge of young people studying in public schools and jeopardizing their future. One of the main ways to get into college in Brazil is through the National High School Exam (ENEM), a multiple-choice test administered by the National Institute of…

It is generally accepted that education in the field of physics is possible only when one has received sufficient grounds for it. But physics is an attempt to understand the world around us. Everything one needs to study physics is an open mind and willingness to learn. It is also commonly thought that preschool-age children have a natural…

The comparative analysis of different meanings of Chemistry is carried out, taking in account philosophical, didactic, psychological and socio-cultural aspects. The issue is discussed in terms of the concurrent existence of two different subsystems referred both to Science and Education which can be found in presentations of chemistry knowledge.…

The relative speed concept was chosen since it is linked with the relative nature of motion and it is likely that the students would harbor many alternative conceptions about it. The research objective was to identify the various ways students conceive relative motion. Qualitative data collected in various forms of representation received a…

The research is focused on the use of experimental calcium cycle in chemistry teaching at the lower secondary school. The cycle is based on four reactions: (1) thermal decomposition of calcium carbonate; (2) reaction of calcium oxide with water; (3) calcium hydroxide with hydrochloric acid; and (4) reaction of calcium chloride with sodium…

This paper investigates differences in students having various scores when designing controlled experiments in two types of scientific inquiry tasks (a fair test and an exhaustive test). We measure temporal features of preparation time and execution time, which reflect respectively the process of question understanding and answer planning and that…

Science assessments should evaluate the full complement of inquiry practices (NGSS, 2013). Our previous work has shown that a large proportion of students' open responses did not match their scientific investigations (Li et al., 2017a). The present study both unpacks and compares the sub-components underlying students' performance for…

The research analyzes the usage of STEAM program "Cognition of Energy and Thermal Processes" for students of ninth (1st Gymnasium) classes in order to deepen and broaden the knowledge of natural science education, develop practical abilities of students and their scientific researcher's competence. Students were advised to do five…
