The concepts of electronegativity and classical electronegativity scales are briefly described. Electronegativity scales have practical quantitative applications, and this work suggests activities which can assist students select the scales for use in chemistry applications. It provided examples of the use of an appropriate electronegativity…

Eigentheory concepts are central in mathematics and physics; they serve multiple functions, such as symbolizing physical phenomena and facilitating mathematical computations. Words and meanings associated with eigentheory develop and vary over time, as do their associated symbols. In this study, we investigate how "eigen" develops over…

The subject of pharmaceutical research has traditionally focused on drugs with systemic effects. However, contemporary approaches aspire to achieve targeted drug delivery, with the aim of combatting infections with a precise immune response. Active substances are encapsulated in nanoparticles, transported through the body, and selectively released…

Hybridization is a bonding model, universally used in organic chemistry, which allows consideration of two-electron localized bonds in organic molecules. Without hybridization, it is almost impossible to describe aspects such as hyperconjugation for the stabilization of carbocations and alkane conformers. Hybridization is often presented in…

Embodied forms of representation like gesture have been shown to play an important role in how learners conceptualize phenomena in physics; however, we know little about how students use gesture to capture the idea of "instantaneity." Drawing on multimodal microanalysis of interaction, we examine how undergraduate physics students use…

Previous research has shown that students employ intuitive thinking when understanding scientific concepts. Three types of intuitive thinking--essentialist, teleological, and anthropic thinking--are used in biology learning and can lead to misconceptions. However, it is unknown how commonly these types of intuitive thinking, or cognitive…

The study of basic chemical reactions can be challenging for teachers in training when addressed in a lecture-based and out of context manner, lacking real-world examples, practical applications, or connections to daily life. Primary Reactions Race is a board game designed to help students learn basic chemical reactions such as oxidation,…

The problem here dealt with concerns physics education, and specifically the concept of force. The idea behind this research is that a historical approach to the teaching of such a notion is of great help for the students to fully understand the meaning of this basic physical magnitude. For, most of scientific concepts can be better grasped by the…

Statement-verification studies indicate the coexistence of intuitive conceptions and scientific concepts within learners. The underlying assumption is that the intuitive conceptions typically built in childhood never disappear, but are co-activated with scientific concepts when we face relevant situations. This is visible in increased reaction…

This study aims to develop and validate a Constructivist Learning Environment Model to address secondary students' misconceptions in learning Science. Employing a Design and Development approach (Richey & Klein, 2007), the research is conducted in two phases. Phase 1 focuses on model design, drawing from an extensive literature review to…

The societal and industrial relevance of chemistry has established its status as a compulsory subject in numerous national curricula. However, previous research highlights significant challenges faced by students in learning chemistry, largely attributed to its abstract nature and the multiple ways chemical concepts are represented. These…

Knowledge about genetics is essential to build a society capable of participating in socioscientific and ethical debates. However, this subject remains difficult for students, making it necessary to develop new educational strategies, such as gamification. Thus, two main objectives are established in this work: (a) to design and evaluate…

The "Vision and Change in Undergraduate Biology Education" report establishes a set of five core concepts that students should build an understanding of throughout college biology programs. While student conceptual understanding is well studied in 4-year contexts, there are minimal studies in community college contexts. Community…

This research investigated the effect of project-based learning (PjBL) on students' conceptual understanding of mechanics. For this purpose, a quasi-experimental research design was conducted with 50 ninth-grade students at Nazarbayev Intellectual School in Kazakhstan. We used the force concept inventory test to measure students' conceptual…

Clearly defining and clarifying crosscutting concepts (CCCs) helps students to apply them as thinking tools or lenses to understand disciplinary core ideas and science and engineering practices. This study identified three characteristics of the sub-concepts of CCCs: conceptual, superordinate, and common across disciplines, and explored a way…
