Solving problems through engineering design: An exploratory study with pre-service teachers
A possible pathway to achieve disciplinary integration is through the use of the Engineering Design (ED) process, starting with problems in a real context that enable the mobilization of concepts from various disciplinary areas. The study reported in this paper aims to analyze the performance underlying the use of the ED process in solving authentic problems in a STEAM perspective, with future teachers of elementary education. We adopted a qualitative and interpretative methodology, with an exploratory design, where data were collected through participant observation, documents, artefacts and photographic records. The results are discussed, taking into account previous research and the data collected throughout the classes, where future teachers solved a problem task and created an artefact and a poster. Preliminary results show that the participants valued the experience and were actively engaged, showing persistence and motivation in solving the problem in a collaborative way, through the different steps of the ED cycle. This approach constituted an opportunity to favor the establishment of connections between different areas, such as mathematics, sciences or arts, detecting the possibility of integrating previously learned concepts. Difficulties were evidenced in the identification of some underlying mathematical and physical sciences concepts, particularly in the mobilization of an adequate scientific language while arguing and making decisions, or in accurately justifying the need to improve the designed plan.0D1E-4824-1244 | Ana Cristina Coelho Barbosainfo:eu-repo/semantics/publishedVersio

Solving authentic problems through engineering design
The importance of STEAM education in pre-
paring students to deal with societal challenges is nowa-
days an international recommendation. We may find
different perspectives concerning STEAM education and
the integration of its disciplines. A possible pathway to
achieve a balanced integration is through Engineering
Design (ED), starting from problems of reality that enable
the articulated mobilization of concepts from various dis-
ciplinary areas, promoting interdisciplinary where team-
work and context play a fundamental role. This article
reports a study with primary preservice teachers (6?12
years old) that aims to analyze the learning displayed
and the difficulties underlying the usage of ED in solving
STEAM problems. The participants were 45 preservice
teachers. We adopted a qualitative methodology, and
data were collected through observation, documents,
artifacts, and photos. The preliminary results show a
very positive reaction of the participants to the experi-
ence of solving real context problems collaboratively and
mobilizing mathematical and physical science concepts
in an integrated way. We identified active engagement,
persistence, and motivation in the creation of a model
that fulfilled the requested conditions. Difficulties were
evidenced in the identification of some concepts and the mobilization of adequate scientific language in the argumentation of decisions.0D1E-4824-1244 | Ana Cristina Coelho Barbosainfo:eu-repo/semantics/publishedVersio

Cohesiveness of powdered co-amorphous Olanzapine and impact on tablet production
Communication abstract: Proceedings of the 5th International Congress of CiiEM - Reducing inequalities in Health and Society, held at Egas Moniz’ University Campus in Monte de Caparica, Almada, from June 16th to 18th, 2021.This is an open access article distributed under the Creative Commons Attribution License which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.The evaluation of the processability of co-amorphous mixtures is of paramount importance since these systems are increasingly used to address the poor solubility presented by most of the drugs in research and development. This work shows that co-amorphous olanzapine powders present higher cohesiveness than their crystalline counterpart and resulted in the production of tablets with a higher tensile strength and a slower release of the drug. As a result, this work demonstrates that despite the solubility advantages of co-amorphous mixtures, consideration should be given to the downstream processing of formulations containing such materials.info:eu-repo/semantics/publishedVersio
