Active learning strategies for an effective mathematics teaching and learning
Get PDFLearning is an active enterprise, where three dimensions stand out, cognitive, social, and
physical, and, in addition, not all students learn in the same way. Grounded on these ideas, this
article reports a study that aims to understand and characterize the performance of pre-service
teachers when experiencing active learning strategies during their mathematics classes. The
participants were 48 future teachers of primary education (3-12 years old) that experienced
paper folding, a gallery walk, and a math trail as active learning strategies. We followed a
qualitative methodology, collecting data though observations, written productions, and
photographic records. The analysis involved a qualitative and inductive approach resorting to
content analysis. The results of the study show that the participants valued these experiences,
due to their potential in the development of a diversity of mathematical concepts and abilities,
and throughout them showed traits of cognitive, social, and physical engagement. Active
learning provided collaborative work and mathematical communication enabling the emergence
of different strategies to solve the proposed tasks. The participants were able to reflect and be
aware of their ideas, mistakes, and difficulties, as well as of others, in a non-threatening
environment, where movement was highlighted for not being a popular dimension in
mathematics classes. Although more research is needed, the results encourage the use of active
learning strategies as a valuable approach to teaching and learning.0D1E-4824-1244 | Ana Cristina Coelho BarbosaN/
An overview of HTTPS and DNSSEC services adoption in higher education institutions in Brazil
Get PDFCyberattacks are performed against all organizations including Higher Education Institutions (HEIs). When these attacks are successful, they can affect the regular operation of these institutions and may cause the leak of essential or sensitive data that can be misused or become inaccessible. Therefore, the
adoption of current security services is important for devices and services exposed to the Internet that should run the latest and secure versions of web-related protocols and comply with the latest security-related guidelines and recommendations. This article surveys and analyzes the status of web-related
security services, namely the Hyper Text Transfer Protocol Secure (HTTPS) and the Domain Name System Security Extensions (DNSSEC) services, in Brazilian HEIs. The results of this survey show that regarding HTTPS around 15% do not use any SSL / TLS certificate and of those supporting it, about 14% do not demand its usage. Regarding DNSSEC, the analysis shows that only around 2% of the HEIs are implementing this protocol. These results show that it is important to design an effective and continuous action plan for HEIs regarding the support or discontinuity of versions of these protocols, in order to improve their protection against cyberattacks.A41D-7428-BA6C | Jackson Barreto Costa Júniorinfo:eu-repo/semantics/publishedVersio

an overview of the fasting state
Get PDFThe Ramadan fasting period (RFP) means abstaining from consuming food and/or bever ages during certain hours of the day—from sunrise to sunset. Engaging in exercise and sports during the RFP leads to the lipolysis of adipose tissue and an increase in the breakdown of peripheral fat, leading to an increase in fat consumption. The effects of the RFP on functional, hematological, and metabolic parameters needs further study as existing studies have reported contradictory results. The differences in the results of various studies are due to the geographical characteristics of Muslim athletes, their specific diets, and their genetics, which explain these variations. In recent years, the attention of medical and sports researchers on the effects of the RFP and energy restrictions on bodily functions and athletic performance has increased significantly. Therefore, this brief article examines the effects of the RFP on the immune system, body composition, hematology, and the functionality of athletes during and after the RFP. We found that most sporting activities were performed during any time of the day without being affected by Ramadan fasting. Athletes were able to participate in their physical activities during fasting periods and saw few effects on their performance. Sleep and nutritional factors should be adjusted so that athletic performance is not impaired.9E1A-F9DD-3EB8 | Filipe Manuel ClementeN/
Úlceras por pressão: evolução do risco em utentes integrados numa equipa de cuidados continuados integrados
Get PDFRelatório de Estágio de Natureza Profissional no âmbito do Mestrado Enfermagem Comunitária apresentada na Escola Superior de Saúde do Instituto Politécnico de Viana do CasteloO presente documento materializa numa síntese crítico reflexiva o processo formativo realizado
no Estágio de Natureza Profissional, desenvolvido no contexto de uma Unidade de Cuidados na
Comunidade. Com o objetivo de consolidar conhecimentos e adquirir competências para
obtenção do grau de Mestre em Enfermagem, com Especialização em Enfermagem Comunitária,
integra, com recurso à atividade de investigação baseada na prática, um estudo sobre avaliação
do risco de Úlceras por Pressão em contexto comunitário. Um dos principais fatores de risco que
contribuem para o aparecimento destas lesões está relacionado com a limitação da mobilidade,
que, por sua vez, está associada ao processo de envelhecimento do indivíduo. Tendo em
consideração o progressivo envelhecimento da população mundial e nacional, é de esperar que
o número de pessoas com este tipo de lesões ou em risco de as desenvolver continue a
aumentar. Para contrariar este cenário, a resposta ao problema passa pela adoção de medidas
eficazes de prevenção A intervenção das Equipas de Cuidados Continuados Integrados visa
promover a autonomia e funcionalidade dos utentes. Este estudo teve como objetivo avaliar a
evolução do risco de úlcera por pressão em utentes que tiveram alta de uma Equipa de Cuidados
Continuados Integrados, de um Agrupamento de Centros de Saúde do Litoral Norte de Portugal,
no ano de 2021. Para avaliação do risco foi utilizada a escala preconizada para os cuidados de
saúde em Portugal, a Escala de Braden (Portugal, 2011). Trata-se de um estudo quasiexperimental,
e de abordagem quantitativa, numa amostra não aleatória, de conveniência
constituída por 45 utentes. Os resultados mostraram uma população maioritariamente feminina
e muito envelhecida, com o grupo etário acima dos 80 anos a representar a maioria da
população do estudo. O teste de Wilcoxon para amostras emparelhadas possibilitou concluir
que o risco de desenvolver úlcera por pressão em utentes que tiveram alta de uma Equipa de
Cuidados Continuados Integrados, de uma Agrupamento de Centros de Saúde do Litoral Norte
de Portugal, no ano de 2021, diminui comparativamente com o momento da sua admissão.The present document materializes, in a critical and reflective synthesis, the formative process
carried out during the Professional Nature Internship, developed within the context of a
Community Care Unit. With the aim of consolidating knowledge and acquiring skills to obtain a
Master's degree in Nursing, with a specialization in Community Nursing, it integrates, using
research-based practice, a study on the assessment of Pressure Ulcer risk in a community
setting. One of the main risk factors contributing to the appearance of these lesions is related
to limited mobility, which, in turn, is associated with the aging process of the individual.
Considering the progressive aging of the global and national population, it is expected that the
number of people with these types of lesions or at risk of developing them will continue to
increase. To counter this scenario, the response to the problem involves the adoption of
effective prevention measures. The intervention of Integrated Continuous Care Teams aims to
promote the autonomy and functionality of the users. This study aimed to evaluate the
evolution of pressure ulcer risk in users who were discharged from an Integrated Continuous
Care Team of a Health Center Group in the Northern Coast of Portugal in the year 2021. The
Braden Scale (Portugal, 2011), a scale recommended for healthcare in Portugal, was used to
assess the risk. This was a quasi-experimental, quantitative approach study, with a non-random
convenience sample of 45 users. The results showed a predominantly female and very aged
population, with the age group above 80 years representing the majority of the study
population. The Wilcoxon test for paired samples allowed us to conclude that the risk of
developing pressure ulcers in users discharged from an Integrated Continuous Care Team of a
Health Center Group in the Northern Coast of Portugal in the year 2021 decreased compared to
the time of their admission
a cross-sectional study in youth soccer players
Get PDFThis study aimed to determine the relationships of locomotor profile (combination of a player’s maximal oxygen uptake and running economy)—measured by the final velocity attained at 30-15 Intermittent Fitness Test (VIFT) and the anaerobic speed reserve (ASR)—with the body composition, countermovement jump (CMJ), sprinting performances, and change-of-direction (COD) ability of youth soccer players. A cross-sectional study design was implemented. A total of 124 youth soccer players from different age groups (15, 16, 17, 18, and 19 years old) were voluntarily recruited. ASR was determined based on the difference between maximal sprint speed (MSS) and VIFT. Players were tested for the following measures: (i) body composition (body mass and body fat percentage); (ii) CMJ (height of jump); (iii) sprinting time measured at 5, 10, 15, 20, 25, and 30 m; (iv) MSS measured in the best split time (5 m) over the 30 m test; (v) COD ability (time, asymmetry index); and (vi) final
velocity at 30-15 IFT (VIFT). A Pearson product-moment correlation test was used to examine the relationships. Height and body mass exhibited large correlations with VIFT (r = 0.835 and r = 0.699, respectively) and small correlations with ASR (r = 0.177 and r = 0.256, respectively). The CMJ was largely correlated with VIFT (r = 0.631 to r = 0.650) while presenting small correlations with ASR (r = 0.227 to r = 0.232). Both VIFT and ASR had moderate (r = 0.3 to r = 0.5) correlations with sprinting time at different distances and very large correlations with MSS (r = 0.797 to r = 0.866). The COD time was largely correlated with VIFT (r = 0.765 and r = 0.775) while exhibiting small-to-moderate correlations with ASR (r = −0.279 and r = −0.301). In conclusion, it was found that locomotor performance at 30-15 VIFT presents high levels of correlation with anthropometry and physical fitness; ASR also presents correlations with these variables, but they are smaller. This suggest that ASR is an independent variable that should be considered for inclusion in information for characterizing
players’ capacities.9E1A-F9DD-3EB8 | Filipe Manuel ClementeN/
O atendimento da pessoa pela via verde do acidente vascular cerebral no serviço de urgência
Get PDFDissertação de Mestrado em Enfermagem Médico-Cirúrgica apresentada na Escola Superior de Saúde do Instituto Politécnico de Viana do CasteloO Acidente Vascular Cerebral (AVC) é a terceira principal causa de morte nos países industrializados. O AVC, é uma condição de emergência médica, e neste sentido foi criada a Via Verde (VV) do AVC, de forma a garantir que as pessoas com sinais e sintomas de AVC sejam prioritárias no seu atendimento.
Pretendemos com este estudo, analisar a intervenção dos profissionais de saúde na implementação do protocolo da VV do AVC no Serviço de Urgência Médico-Cirúrgica (SUMC).
Para dar resposta a este objetivo foi realizado um estudo qualitativo, de natureza descritiva e exploratória num SUMC de um hospital do norte de Portugal. Foram realizadas entrevistas semiestruturadas aos profissionais de saúde envolvidos na prestação direta de cuidados à pessoa com VV do AVC e efetuada observação dos mesmos. Os dados foram analisados com o recurso à análise de conteúdo de acordo com Laurence Bardin (2010) e análise estatística descritiva.
Após a análise dos dados obtidos, emergiram os resultados que demonstram que os profissionais de saúde conhecem as intervenções que têm de desempenhar e foram identificadas dificuldades e sugestões de melhoria na implementação da VV do AVC. Tanto nos fatores dificultadores como nas sugestões de melhoria sobressaem a Triagem de Manchester (TM), o Serviço de Radiologia e os recursos humanos e materiais, entrecruzando-se assim. Podemos também verificar que nas observações efetuadas, estas cumprem maioritariamente os tempos definidos pelas Guidelines da American Heart Association (AHA).
Os participantes responderam unanimamente que a prioridade é a realização de exame de neuroimagem. A Equipa de Enfermagem sente algumas dificuldades na implementação do protocolo da VV do AVC, reportando-se à Triagem de Manchester.
Como sugestões de melhoria sobressaíram a Formação e Treino em Equipa, melhoria da comunicação, otimização dos recursos Humanos e materiais e uma avaliação médica inicial mais rápida.
Os resultados obtidos neste estudo proporcionam informação para o desenvolvimento de um pensamento crítico, com o intuíto de melhoria e aperfeiçoamento dos profissionais de saúde, no atendimento da pessoa pela VV do AVC.Stroke is the third leading cause of death in industrialized countries, after heart disease and cancer. Stroke is a condition of medical emergency, and in this sense the Stroke Code protocol was created, in order to ensure that people with signs and symptoms of stroke are given priority in their care.
With this study, we intend to analyze the intervention of health professionals in the implementation of the stroke VV protocol in the Medical-Surgical Emergency Service (MSES).
In order to respond to this objective, a qualitative, descriptive and exploratory study was carried out in a MSES from a hospital in the north of Portugal. Semi-structured interviews were carried out with health professionals involved in the direct provision of care to people with VV of stroke and their observation was carried out. Data were analyzed using content analysis according to Laurence Bardin (2010) and descriptive statistical analysis.
After analyzing the data obtained, the results emerged that demonstrate that health professionals know the interventions they have to perform and difficulties and suggestions for improvement in the implementation of the Stroke Code protocol were identified. Both in the hindering factors and in the suggestions for improvement, the Manchester Triage, the Radiology Service and the human and material resources stand out, intersecting in this way. We can also verify that in the observations made, these mostly comply with the times defined by the Guidelines of American Heart Association (AHA).
Participants unanimously responded that the priority is to perform a neuroimaging exam. The Nursing Team experiences some difficulties in implementing the stroke VV protocol, reporting to the Manchester Triage.
Suggestions for improvement included Team Training and Training, improved communication, optimization of human and material resources and a faster initial medical assessment.
The results obtained in this study provide information for the development of critical thinking, with the aim of improving and perfecting health professionals in caring for people with Stroke Code protocol
Solving authentic problems through engineering design
Get PDFThe 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
Mathematical communication: the articulation between seeing, hearing and speaking
No full textDurante uma aula de matemática, escolhemos tarefas matemáticas que evocam matemática significativa e motivam os alunos a discutir o seu pensamento matemático? Uma ideia é apresentada e/ou compreendida da maneira que queremos? A natureza das tarefas propostas na sala de aula de matemática, bem como a natureza do questionamento e da discussão promovida pelo professor têm
claras implicações na qualidade da comunicação estabelecida na sala de aula, e consequentemente,
na aprendizagem dos alunos. Comunicar uma ideia ou pensamento a outra pessoa, de forma clara,
requer organização e conhecimento de factos e conceitos precisos, porém isso nem sempre é feito e/ou
entendido como planeado. Salientando que podemos comunicar de diferentes maneiras - formalmente
ou informalmente, oralmente, por escrito ou usando gestos. Destacamos os contextos visuais como um
forte apoio para a compreensão e explicação de conceitos e ideias, especialmente para os alunos mais
jovens. Nesta comunicação apresenta-se um estudo onde se discute as dificuldades e reações de futuros
professores em relação a tarefas que privilegiam diferentes formas de comunicação em contextos visuais. As tarefas propostas concentram-se em ver as informações diretamente ou ouvir as informações sem ver. Este estudo de natureza qualitativa foi desenvolvido com futuros professores de educação básica numa disciplina no âmbito da didática da matemática. Os resultados mostram que os alunos reagiram positivamente às tarefas propostas, manifestando interesse e motivação apesar de algumas dificuldades reveladas na comunicação. Reconheceram as dificuldades sentidas na realização de algumas tarefas e constataram o seu potencial para desenvolver/melhorar o conhecimento matemático e o discurso matemático.0D1E-4824-1244 | Ana Cristina Coelho Barbosainfo:eu-repo/semantics/publishedVersio
The impact of written feedback in geometry problem solving through a Gallery Walk
Get PDFTraditionally, students experience difficulties solving problems involving
geometric shapes and their properties. In line with the current curricular
guidelines, it’s important to reflect about the use of active learning strategies,
which directly engage students in meaningful mathematical activity, that
contribute to reverse this situation. This paper refers to a study that aims to
understand the influence of peer written feedback on students' performance in a
Gallery Walk context, in the scope of problem solving involving areas of plane
figures. We followed a qualitative, interpretative approach and collected data in a
5th grade class, with 19 students, through participant observation, a questionnaire,
interviews, written productions and photographic records. Results show that, when
the sender of feedback is a student, different types of feedback are used, however
not all of them promote the improvement of the receiver’s performance. It was
noticed that the most effective feedback is focused mainly on the emerging
mathematical content, commenting on the student's performance in terms of task
solution, process and results. It was also found that the feedback must be clear and
simple so that the receiver clearly understands what the sender wants to convey.0D1E-4824-1244 | Ana Cristina Coelho Barbosainfo:eu-repo/semantics/publishedVersio
