Marble, formed by the metamorphism of limestone, is commonly used in the construction industry and sculpting. The mineral in marble is either calcite [CaCO[subscript 3]] or dolomite [CaMg(CO[subscript 3])[subscript 2]] or sometimes both. The pure white Carrara marble from Italy was made a household name by Michelangelo, the famous sculptor of the…

The inquiry-based approach is a teaching strategy that facilitates students learning scientific concepts and about the nature of chemistry through experimental research, allowing them to participate in chemistry classes as researchers. The methodology employed in chemistry learning in Brazil is based on the traditional teaching approach, and…

As part of their third-year general chemistry program, students at the University of the Côte d'Azur are taught the basics of radioactivity. The view that third-year university students have of the periodic Table of the Elements is often reduced because it ignores the vast majority of isotopes. As part of this program, a practicum devoted to the…

Analogies can be powerful teaching tools because they can make new material intelligible to students by comparing it to material that is already familiar. In assisting students to understand chemistry concepts, teachers occasionally use analogies. These analogies are believed to help the students to structure the new knowledge and they are…

Giving feedback to peers can be a valuable learning experience for a feedback provider. However, different types of products require different types of feedback, which, in turn, may lead to different learning outcomes. The current study investigates the effect on the learning of feedback providers of reviewing different types of products.…

Learning science outdoors can enhance the understanding of theoretical scientific content taught in the classroom. However, learners are rarely afforded the opportunity to go outdoors to learn chemistry. This study investigates how problem-based learning outdoors can facilitate the understanding of basic chemistry in teacher education. A teaching…

Symbolic, spatial, and visual information, which is important for comprehending and learning physical and natural sciences, is not readily accessible to blind and low-vision (BLV) students in the undergraduate chemistry classroom, laboratory, and virtual environment via conventional means (through print and images), thus, creating a…

Graduate training is a key element in producing a scientific workforce that reflects the nation's diversity. This paper examines data from a 2013 American Chemical Society (ACS) survey of 2,544 chemistry masters and doctoral students and reveals barriers to reaching this goal. Multivariate statistical analyses indicate that women reported…

Intercultural competence (IC) training in the professional development of international graduate Teaching Assistants (ITAs) can pave the way for more inclusive chemistry classroom environments that allow all students access to opportunities and resources to learn chemistry. IC principles are laid out, including how they connect to Diversity,…

Learning chemistry in an online environment may have multiple sources of anxiety for students, including chemistry anxiety, math anxiety, computer anxiety, and trait anxiety (personality attribute of proneness to experience anxiety). While previous research has explored relationships between math and chemistry anxiety in a traditional setting, no…

Many colleges and universities take a "weeding out the weak" approach to teaching STEM, despite substantial literature that emphasizes the values and effectiveness of various other approaches. Introductory, foundational, STEM courses which are often taken by students during their first and second years of college, have been shown to…

This study describes the development, validity, and reliability processes of a scientific creativity test for pre-university students, specifically in chemistry. A Chemistry Scientific Creativity Test (CSCT) was constructed based on an analysis of the Scientific Creativity Structure Model (SCSM), Torrance Tests of Creative Thinking (TTCT), and…

We present an example of a novel, model-based approach to instruction in which learners constructed a representation of a specific phenomenon, evaluated their representation, and then revised it, via an abstraction process, to construct a model. The example took place in high school in the context of solution chemistry. The aim of the instruction…

This study is an exploratory comparison of 69 Hispanic students enrolled in first-semester general chemistry (Chem I) who attended either a Hispanic-Serving or emerging Hispanic-Serving Institution and were not successful in Chem I. Students' automaticity skills (what can be done without the aid of a calculator) in arithmetic and quantitative…

Pre-service teachers who conduct experiments are faced with various risks in terms of physical, health and environment due to the chemicals they are exposed to in the laboratory classes. Working in a laboratory without knowing these risks causes accidents such as chemical spills, explosions and fires, and even individual injuries. For this reason,…
