Costantino, Luca; Barlocco, Daniela – Journal of Chemical Education, 2019
This article presents the structure of the organic chemistry laboratory Course "Synthesis and Extraction of Drugs" that is included in Modena University (Italy) in the third year of the five-year "Chemistry and Pharmaceutical Technologies" degree program. This course is unique in its kind, and it aims to provide students with…

Leonello, Rocco; Savio, Matteo; Toaldo, Paola Baron; Bonomi, Renato – Journal of Chemical Education, 2018
Determination of enzymatic activity is a relevant experiment in teaching chemistry and biochemistry to high school and college students. A method for measuring the kinetic parameters of lactose cleavage by the enzyme lactase is described. This enzyme catalyzes the hydrolysis of lactose to galactose and glucose. The kinetic parameters can be…

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…

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).

Celestino, Teresa; Marchetti, Fabio – Journal of Chemical Education, 2015
Educating future scientists and citizens is more effective if students are guided to correctly apply what they learned in school to their daily lives. This experience-based work is focused on the study of a well-known commercial product: cat litter. This material offers different starting points for a critical examination. Questions related to…

Pezzolo, Alessandra De Lorenzi – Journal of Chemical Education, 2011
In this experiment, students are given a fanciful application of the standard addition method to evaluate the approximate quantity of the shell component in a sample of sand collected on the Lido di Venezia seashore. Several diffuse reflectance infrared Fourier transform (DRIFT) spectra are recorded from a sand sample before and after addition of…

Smieja, Joanne A.; D'Ambruoso, Gemma D.; Richman, Robert M. – Journal of Chemical Education, 2010
Three related courses examining the connection between chemistry and art have been developed for study-abroad programs in Florence, Italy, by faculty members at Gonzaga University and Mount Saint Mary's University. These courses are described with the intent of providing a general framework for the development of chemistry and art courses in other…

Domenici, Valentina – Journal of Chemical Education, 2008
This paper investigates the educational role of museums of chemistry in presenting chemistry to the public in Italy, particularly to students. The activities carried out by Italian museums and scientific collections completely dedicated to chemistry have been analyzed, focusing on the relationship between these institutions and students with…

Regis, Alberto; Albertazzi, Pier Giorgio – Journal of Chemical Education, 1996
Describes the use of concept maps as a metacognitive tool to help chemistry teachers and learners improve teaching and learning. Concept maps were used in response to changes in the conceptions of the nature of scientific knowledge and in how learning occurs. Concept maps are valuable in documenting and exploring the restructuring of conceptual…

Cervellati, R.; And Others – Journal of Chemical Education, 1982
Discusses: (1) how mole concept is defined/used in textbooks; (2) development and administration of a multiple-choice test to secondary school pupils (N=783) in Bologna and the surrounding district; and (3) results of the diagnostic examination, focusing on student mistakes and misconceptions.

Cervellati, R.; Perugini, D. – Journal of Chemical Education, 1981
Freshmen college students (N=290) were asked, "What is an atomic orbital?" as a measure of their knowledge after completing high school chemistry. Results suggest that high school chemistry be divided into two levels: (1) procedures and interpretations of classical chemistry and (2) introduction of elementary quantum chemical concepts.…
