Vieira, Hugo; Morais, Carla – Journal of Chemical Education, 2022
Scientific literacy is an important skill for students' success, given the characteristics of today's society. However, not all students have a natural predisposition toward science, chemistry in particular. Considering the relevance of transdisciplinary learning, schools should foster the scientific abilities for which students may have less…

Saccharin Derivative Synthesis via [1,3] Thermal Sigmatropic Rearrangement: A Multistep Organic Chemistry Experiment for Undergraduate Students
Peer reviewed Peer reviewed

Fonseca, Custódia S. C. – Journal of Chemical Education, 2016
Saccharin (1,2-benzisothiazole-3-one 1,1-dioxide) is an artificial sweetener used in the food industry. It is a cheap and easily available organic compound that may be used in organic chemistry laboratory classes for the synthesis of related heterocyclic compounds and as a derivatizing agent. In this work, saccharin is used as a starting material…

Sousa, Joao Carlos; Costa, Manuel Joao; Palha, Joana Almeida – Biochemistry and Molecular Biology Education, 2010
The biochemistry and molecular biology of the extracellular matrix (ECM) is difficult to convey to students in a classroom setting in ways that capture their interest. The understanding of the matrix's roles in physiological and pathological conditions study will presumably be hampered by insufficient knowledge of its molecular structure.…

The Mechanism of Guard Cell Movement
Peer reviewed Peer reviewed

Marques, M.; Arrabaca, J.; Chagas, I. – Journal of Biological Education, 2005
Leaves of higher terrestrial plants have small pores--stomata--responsible for gas exchange. The opening of each stoma results from the osmotic uptake of water by two specialised cells--the guard cells. Because of the involvement in this mechanism of ATPase-proton pumps and active transport of ions across membranes, we have designed an Exploring…

Pupils' Representations of Models of Water.
Peer reviewed Peer reviewed
Pereira, Mariana P.; Pestana, Maria Elisa M. – International Journal of Science Education, 1991
The pencil-and-paper assignment "Represent water in its three states using a model" was given to pupils (n=227) from eighth to twelfth grades. The findings show that the dominant model used was the space filling type; movement of particles was indicated by a minority of pupils; size of the model changed when drawn in different states.…
