Problem formulation in a 4th grade class
Faria, Joana; Mascarenhas, Daniela; Silva, Nuno Miguel; Quadros-Flores, PaulaThis article will present research on the formulation of problems, using the strategy "accepting the data", within the domain Numbers and Operations, in the 4th grade. It is a didactic unit, which the aim is to understand "What are the benefits of problem formulation in the learning of 4th grade students? To this objective, a mixed methodology was followed, having developed the study with 19 students’ 4th grade...
Cellulosic Textile Materials Functionalization with Formic Acid and Improvement...
Faria, Joana; Padrão, Jorge; Zille, Andrea; Miranda, TeresaFormic acid, commonly used in bioprocesses of cellulosic polymeric materials, has been considered for the treatment of cellulose-based textile. Therefore, different concentrations of formic acid (10, 20, 30, 40, and 50 g L-1) were used to treat cotton (CO) and viscose (CV) fabrics to improve their properties. Weight variation, tensile strength, stiffness, drape coefficient, crease recovery angle, and vertical w...
Welcoming refugees in Portugal: preliminary assessment through the voices of re...
Barbosa, Mariana; Santos, Mafalda; Veiga, Elisa; Martins, Filipe; Ribeiro, Maria Teresa; Faria, JoanaThe Refugee Support Platform (PAR – Plataforma de Apoio a Refugiados) was created in September 2015 through the establishment of a network of organisations and volunteers from the Portuguese civil society. PAR Families is a program that aims to provide support to refugee families in Portugal. PAR Families model implies that for each family of refugees arriving in the country there will be an institution directl...
Ensinar e aprender em universidades seniores: conceções sobre a estrutura da Terra
Pinheiro, Ana; Faria, Joana; Cardoso, Alexandra; Ribeiro, Tiago; Vasconcelos, ClaraVários estudos alertam para a baixa literacia científica evidenciada por cidadãos portugueses das várias idades. A maioria das investigações abordam estas conceções junto de crianças ou jovens, mas pouco é referido na literatura sobre cidadãos seniores. Dado o aumento da esperança de vida em Portugal, o número de associados das universidades seniores tem vindo a aumentar, sendo necessário intervir, potenciando ...
Ensinar e aprender ciências na universidade sénior: conceções sobre possíveis c...
Pinheiro, Ana; Faria, Joana; Cardoso, Alexandra; Ribeiro, Tiago; Vasconcelos, ClaraA promoção e o desenvolvimento da literacia científica consideram-se, cada vez mais, como aspetos fundamentais para a formação de cidadãos informados. No entanto, são vários os estudos que apontam o baixo nível de literacia científica entre os cidadãos seniores. Considerando o aumento da esperança média de vida em Portugal, as Universidades Sénior surgem como alternativas ocupacionais às gerações mais velhas, o...
On estimating the gross primary productivity of Mediterranean grasslands under ...
Cerasoli, Sofia; Campagnolo, Manuel; Faria, Joana; Nogueira, Carla; Caldeira, M.ConceiçãoWe applied an empirical modelling approach for gross primary productivity (GPP) estimation from hyperspectral reflectance of Mediterranean grasslands undergoing different fertilization treatments. The objective of the study was to identify combinations of vegetation indices and bands that best represent GPP changes between the annual peak of growth and senescence dry out in Mediterranean grasslands. In situ hyp...
Bloqueio TAP subcostal contínuo bilateral como técnica anestésica no doente crí...
Faria, Joana; Tarroso, Maria; Lages, Neusa; Correia, CarlosEste caso descreve a realização de um bloqueio do plano transverso abdominal (TAP) subcostal contínuo bilateral associado a sedação leve numa paciente de alto risco proposta para encerramento de laparostomia, proporcionando relaxamento adequado da parede abdominal, manutenção da ventilação espontânea e analgesia pós-operatória eficaz. A técnica permitiu evitar a utilização de bloqueadores neuromusculares e dose...
Problem Based Learning at the service of new knowledge production
Almeida, António; Vasconcelos, Clara; Faria, Joana; Pereira, ConceiçãoScience Education has sought methods that can promote connections to real situations and also improve significant learning experiences. Problem Based Learning (PBL) has proved to be an effective methodology to this purpose. Initially implemented in Medicine in 1969, it has been extended to other scientific fields during the last decades.
Geology in the lab: preliminar studies for validating a checklist for analysing...
Vasconcelos, Clara; Faria, Joana; Almeida, António; Dourado, L.Models and modelling activities play a central role in the making and understanding of science [1], making the learning of science more meaningful and helping students to build appropriate mental models [2, 3]. When students learn with models, they build mental ones that are more consistent with scientific models. This reconstruction process is generally complex and generates many cognitive conflicts. It was on...
