Garino, Claudio; Terenzi, Alessio; Barone, Giampaolo; Salassa, Luca – Journal of Chemical Education, 2016
Among computational methods, DFT (density functional theory) and TD-DFT (time-dependent DFT) are widely used in research to describe, "inter alia," the optical properties of transition metal complexes. Inorganic/physical chemistry courses for undergraduate students treat such methods, but quite often only from the theoretical point of…

Big Atoms for Small Children: Building Atomic Models from Common Materials to Better Visualize and Conceptualize Atomic Structure
Peer reviewed Peer reviewed
Direct linkDirect link
Cipolla, Laura; Ferrari, Lia A. – Journal of Chemical Education, 2016
A hands-on approach to introduce the chemical elements and the atomic structure to elementary/middle school students is described. The proposed classroom activity presents Bohr models of atoms using common and inexpensive materials, such as nested plastic balls, colored modeling clay, and small-sized pasta (or small plastic beads).

A Model for the Development of University Curricula in Nanoelectronics
Peer reviewed Peer reviewed
Direct linkDirect link
Bruun, E.; Nielsen, I. – European Journal of Engineering Education, 2010
Nanotechnology is having an increasing impact on university curricula in electrical engineering and in physics. Major influencers affecting developments in university programmes related to nanoelectronics are discussed and a model for university programme development is described. The model takes into account that nanotechnology affects not only…

Ambrogi, Paola; Caselli, Monica; Montalti, Marco; Venturi, Margherita – Chemistry Education Research and Practice, 2008
A class in a Scientific-Technological Lyceum (age 17) decided to produce a PowerPoint presentation to introduce nanochemistry and nanotechnology to the students in lower grades. Because the subject is very new, there was nothing in the School textbooks and, therefore, the students had to cooperate in order to find materials, to use ICT sources and…

Active/Cooperative Learning in Schools
Peer reviewed Peer reviewed
Direct linkDirect link
Bandiera, Milena; Bruno, Costanza – Journal of Biological Education, 2006
The study describes a teaching action undertaken in the belief that the use of methodologies based on active and cooperative learning could obviate some of the most worrying deficiencies in current scientific teaching, while at the same time supporting the validity of the constructivistic theory that prompted them. A teaching action on genetically…

Feynman Diagrams as Metaphors: Borrowing the Particle Physicist's Imagery for Science Communication Purposes
Peer reviewed Peer reviewed
Direct linkDirect link
Pascolini, A.; Pietroni, M. – Physics Education, 2002
We report on an educational project in particle physics based on Feynman diagrams. By dropping the mathematical aspect of the method and keeping just the iconic one, it is possible to convey many different concepts from the world of elementary particles, such as antimatter, conservation laws, particle creation and destruction, real and virtual…
