Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I (GCI), reintroduced in Organic Chemistry I (OCI), and then utilized throughout other higher-level chemistry courses. Student difficulties with resonance are well documented. Instruction is one potential source of student difficulties. What instructors…

Many studies have reported various interventions to increase critical thinking, but very few studies have examined the impact of learning in classrooms and laboratories. This study aimed to find a learning pattern (practice to theory or theory to practice) in improving students' critical thinking skills (CTs). Pre and posttest nonequivalent group…

An immense body of literature on astronomy studies has provided evidence that individuals perceive the lunar phases concept as difficult. Furthermore, many studies have shown erroneous explanations or alternative conceptions of lunar phases. However, there is also a need to understand how individuals construct an explanation of the Moon's phases.…

As science and technology create an ecosystem that is becoming increasingly more knowledge-intensive, complex, and interconnected, the next generation science standards include systems thinking and systems modeling among 21st skills that should be fostered. We examined the effect of an online cross-disciplinary learning process on the development…

Visualisation has been a critical means of scientific reasoning, knowledge development, and communication. In science classrooms, visualisation plays significant roles for teaching and learning. To better understand the landscape of the existing research on visualisation for supporting student science learning in K to 12 classroom contexts, we…

Australia-wide consensus was reached on seven core concepts of physiology, which included homeostasis, a fundamental concept for students to understand as they develop their basic knowledge of physiological regulatory mechanisms. The term homeostasis is most commonly used to describe how the internal environment of mammalian systems maintains…

The limited time allocation for lectures in the classroom is an obstacle to presenting student-centered learning. This is one of the factors that prospective physics teacher students experience conceptual difficulties, especially in crystal structure material. So the purpose of this study was to determine the effectiveness of the problem flipped…

Promoting student understanding of biological concepts is a key part of biology education, and the ability to "understand" a concept forms one of the six categories of the oft-used Bloom's Taxonomy. Despite this, there remains no consensus as to what it means to understand a concept. While several formal definitions have been offered, we…

Understanding scientific models and practicing scientific modeling have been emphasized and advocated in science learning. Although teachers have been perceived as shaping their students' understanding of the nature of science, they have been recognized for their lack of understanding of scientific models. This study explores middle school science…

The mole concept is one of the fundamental concepts in chemistry. However, a number of studies carried out in various countries have shown that teachers and learners face many difficulties in teaching and learning the concept. One of the underlying sources of teaching and learning difficulties of the mole concept identified in literature is the…

In 2019 India was ranked seventh most affected nation by climate change, yet 65 per cent of the Indian population had not heard of climate change. India's revised National Education Policy mentions climate change and environmental issues as part of its work towards reaching the United Nation's Sustainable Development Goals. However, to date,…

Today, science education demands preparation of scientifically literate people, emphasizing more the process of working with information than owning it. Such a task requires a deep understanding of pedagogical content knowledge by science teachers. This study focuses on revealing the beliefs of prospective chemistry teachers during their teaching…

Literature on school education suggests that teaching and learning science in basic level community schools in Nepal is largely theoretical. Consequently, achievement levels and the understanding of concepts of science is much below policy expectations. This paper builds on a shift from dogmatic lecturing to activity-based pedagogy using school…

This study aimed to develop pre-service science teachers' conceptual understanding of a nanoscience project through a newly introduced 8E learning cycle. This research was conducted during one semester of a nanoscience and nanotechnology course in the chemistry education department in Universitas Negeri Jakarta, Indonesia with thirty-three…

The object of this study is to determine the conceptual understanding that prospective Science teachers have relating "de Broglie: Matter waves" and to investigate the effect of the instruction performed, on the conceptual understanding. This study was performed at a state university located in the western part of Turkey, with the…
