This study aimed to construct and carry out a distance course of pedagogical training for health professional performing preceptorship functions in public health institutions. The preceptorship in health is a pedagogical practice that occurs in workplace, led by assistance professionals with teaching position or not, where the vast majority of these acts intuitively, reproducing their own training, confusing transmitting information with education. These preceptors often do not dominate the pedagogical knowledge, necessary for the organization of training activities, such as the various teaching-learning processes and the different assessment types. Student supervision is essential in the training process of students in the health field, and on the occasion of supervised internships that the teaching-learning process is based on practical experience with participation in real life situations and professional work. It was realized an exploratory study, descriptive with qualitative approach, with the development of tutoring teaching course in health as final product. Applied semi structured research instrument from may to july 2014. It were evaluated 162 health professionals who perform the preceptorship, which made it possible define the preceptor's profile and identify the educational requirements related to the educational process, which justified the construction of the program content and the professionals’ perception analysis about preceptorship through identification of three categories: clinic knowledge valuation; valuation of professional orientation and valuation of professional future. The course was available on distance mode through Moodle platform with forty hours of work load from October to November 2014. With the aim of capacitate the health professionals to development of necessary abilities and skills to tutoring performance through thoughts about tutoring concepts, professional training within the curricular guidelines and SUS precepts, the role of health professionals as educators, application of active teaching methodologies, and evaluation methods. The applications were done online through the provided link; 300 vacancies offered, 243 professionals applied, chosen 134 that works on tutoring, where 49 represented professionals that works on the location of the study. The course lasted 45 days, and counted with tutors responsible to interact and evaluate the students. 28 professionals joined the course, 12 concluded. Opportunities were identified to stimulate the involvement, however the professionals’ satisfaction shows that, make an investment on tutors education, starting from the Permanent Education precepts, will provide a bigger appropriation of the knowledge to the education and therefore the awareness of their role as an educator on work ambit, proportioning essential tools to tutors act while enabler of integration between theory and practice and result better teaching-learning process.

The paper reports on a study of design studio culture from a student perspective. Learning in design studio culture has been theorised variously as a signature pedagogy emulating professional practice models, as a community of practice and as a form of problem-based learning, all largely based on the study of teaching events in studio. The focus of this research has extended beyond formally recognized activities to encompass the student’s experience of their social and community networks, working places and study set-ups, to examine how these have contributed to studio culture and how there have been supported by studio teaching. Semi-structured interviews with final year undergraduate students of architecture formed the basis of the study using an interpretivist approach informed by Actor-network theory, with studio culture featured as the focal actor, enrolling students and engaging with other actors, together constituting an actor-network of studio culture. The other actors included social community patterns and activities; the numerous working spaces (including but not limited to the studio space itself); the equipment, tools of trade and material pre-requisites for working; the portfolio enrolling the other actors to produce work for it; and the various formal and informal events associated with the course itself. Studio culture is a highly charged social arena: The question is how, and in particular, which aspects of it support learning? Theoretical models of situated learning and communities of practice models have informed the analysis, with Bourdieu’s theory of practice, and his interrelated concepts of habitus, field and capital providing a means of relating individually acquired habits and modes of working to social contexts. Bourdieu’s model of habitus involves the externalisation through the social realm of habits and knowledge previously internalised. It is therefore a useful model for considering whole individual learning activities; shared repertoires and practices located in the social realm. The social milieu of the studio provides a scene for the exercise and display of ‘practicing’ and the accumulation of a form of ‘practicing-capital’. This capital is a property of the social milieu rather than the space, so working or practicing in the company of others (in space and through social media) becomes a more valued aspect of studio than space or facilities alone. This practicing-capital involves the acquisition of a habitus of studio culture, with the transformation of physical practices or habits into social dispositions, acquiring social capital (driving the social milieu) and cultural capital (practicing-knowledge) in the process. The research drew on students’ experiences, and their practicing ‘getting a feel for the game’ by exploring the limits or boundaries of the field of studio culture. The research demonstrated that a notional studio community was in effect a social context for supporting learning; a range of settings to explore and test out newly internalised knowledge, demonstrate or display ideas, modes of thinking and practicing. The study presents a nuanced interpretation of how students relate to a studio culture that involves a notional community, and a developing habitus within a field of practicing that extends beyond teaching scenarios.

Background and aims: Machine learning techniques for the text mining of cancer-related clinical documents have not been sufficiently explored. Here some techniques are presented for the pre-processing of free-text breast cancer pathology reports, with the aim of facilitating the extraction of information relevant to cancer staging.
Materials and methods: The first technique was implemented using the freely available software RapidMiner to classify the reports according to their general layout: ‘semi-structured’ and ‘unstructured’. The second technique was developed using the open source language engineering framework GATE and aimed at the prediction of chunks of the report text containing information pertaining to the cancer morphology, the tumour size, its hormone receptor status and the number of positive nodes. The classifiers were trained and tested respectively on sets of 635 and 163 manually classified or annotated reports, from the Northern Ireland Cancer Registry.
Results: The best result of 99.4% accuracy – which included only one semi-structured report predicted as unstructured – was produced by the layout classifier with the k nearest algorithm, using the binary term occurrence word vector type with stopword filter and pruning. For chunk recognition, the best results were found using the PAUM algorithm with the same parameters for all cases, except for the prediction of chunks containing cancer morphology. For semi-structured reports the performance ranged from 0.97 to 0.94 and from 0.92 to 0.83 in precision and recall, while for unstructured reports performance ranged from 0.91 to 0.64 and from 0.68 to 0.41 in precision and recall. Poor results were found when the classifier was trained on semi-structured reports but tested on unstructured.
Conclusions: These results show that it is possible and beneficial to predict the layout of reports and that the accuracy of prediction of which segments of a report may contain certain information is sensitive to the report layout and the type of information sought.

This multi-perspectival Interpretive Phenomenological Analysis (IPA) study explored how people in the ‘networks of concern’ talked about how they tried to make sense of the challenging behaviours of four children with severe learning disabilities. The study also aimed to explore what affected relationships between people. The study focussed on 4 children through interviewing their mothers, their teachers and the Camhs Learning Disability team members who were working with them. Two fathers also joined part of the interviews. All interviews were conducted separately using a semi-structured approach. IPA allowed both a consideration of the participant’s lived experiences and ‘objects of concern’ and a deconstruction of the multiple contexts of people’s lives, with a particular focus on disability. The analysis rendered five themes: the importance of love and affection, the difficulties, and the differences of living with a challenging child, the importance of being able to make sense of the challenges and the value of good relationships between people. Findings were interpreted through the lens of CMM (Coordinated Management of Meaning), which facilitated a systemic deconstruction and reconstruction of the findings. The research found that making sense of the challenges was a key concern for parents. Sharing meanings were important for people’s relationships with each other, including employing diagnostic and behavioural narratives. The importance of context is also highlighted including a consideration of how societal views of disability have an influence on people in the ‘network of concern’ around the child. A range of systemic approaches, methods and techniques are suggested as one way of improving services to these children and their families. It is suggested that adopting a ‘both/and’ position is important in such work - both applying evidence based approaches and being alert to and exploring the different ways people try and make sense of the children’s challenges. Implications for practice included helping professionals be alert to their constructions and professional narratives, slowing the pace with families, staying close to the concerns of families and addressing network issues.

The UK has been criticised for its inequitable education system, as student outcomes are strongly linked to parental socio-economic status. Children and young people experiencing poverty are less likely than their better off peers to leave school with good grades, which can perpetuate disadvantage in later life. The attainment gap between children and young people experiencing poverty and their better off peers in the UK is widening, despite an increasing media and policy focus in this area. Poverty-related educational inequality is a complex area and there is no conclusive evidence in what works to reduce its effects. While there is a plethora of research on the impact of poverty on education, very little of it includes the voice of children and young people and/or the psychological impact of poverty on learning. The importance of hearing the views of children and young people is central to educational psychology, as is social justice and facilitating access to the curriculum for all students. The barriers presented by the experience of poverty to learning are thus vital for educational psychologists to address. This study used qualitative methods to explore the learning journey of Key Stage 3 (age 12-13) young people experiencing poverty in an English coastal borough. Questions from the Little Box of Big Questions 2 were used as a tool in semi-structured interviews, in addition to questions devised by the researcher. Young people discussed aspects of their lives that enabled them to learn at school, and aspects that presented barriers to learning. The research used Positive Psychology, taking a strengths based approach to explore the skills young people thought they brought to education, skills they would like to develop, and how they could be supported in this. The study has highlighted themes that, if addressed, could potentially raise the attainment of children and young people experiencing poverty.

The purpose of this study is to understand, impact and evaluate the development of intercultural communicative competencies among European credit-seeking exchange students and other sojourners through purposeful intercultural pedagogy. This pedagogy encompasses intentional intercultural- educational approaches which aim to support and enhance sojourners’ intercultural learning throughout the study abroad cycle (pre-departure, in-country and reentry phases). To test and validate these pedagogies a 20-hour intervention was designed and implemented among two cohorts of 31 sojourners during the in-country phase of their sojourn in Portugal. The process to develop and validate the intercultural intervention was driven by a mixed-methods methodology which combined quantitative and qualitative data to triangulate, complement and expand research results from a pragmatic stance. The mixed methods research design adopted is multi-phased and encompasses a multi-case study and an evaluative component. The multi-case component is embodied by sojourner cohorts: (1) the primary case study involves 19 incoming students at the University of Aveiro (Portugal) as participants in the European exchange program Campus Europae; (2) the second case study comprises three incoming Erasmus students and nine highly skilled immigrants at the same university. All 31 sojourners attended two intermediate Portuguese as Foreign Language classrooms where the intervention was employed. Data collection was extensive and involved collecting, analyzing and mixing quantitative and qualitative strands across four research phases. These phases refer to the: (1) development, (2) implementation and (3) evaluation of the intervention, as well as to (4) a stakeholder analysis of the external value of the intervention and of the Campus Europae program. Data collection instruments included pre and posttest questionnaires and semi-structured interviews. Results confirm the intercultural effectiveness of the intervention and the positive impact upon research participants’ intercultural gains. This impact was, however, greater in case study 2. Among explanatory variables, three stand out: (1) participant meaning-making abilities, (2) host language proficiency and related variables, and (3) type of sojourn or exchange programs. Implications for further research highlight the need to systematize purposeful intercultural pedagogy in sojourner populations in general, and in European credit student mobility in particular. In the latter case, these pedagogies should be part of the design and delivery of credit-bearing exchange programs in pre- departure, in-country and re-entry phases. Implications for practice point to the urge to improve intercultural practices in: macro (higher education institutions), mezzo (exchange programs) and micro (sojourner language classrooms) contexts where this research took place, and wider social scenarios they represent.

O presente artigo tem como objetivo refletir sobre o impacto das TIC em contexto educativo, focando os potenciais contributos da utilização dos Recursos Educativos Digitais (RED) no processo de ensino e de aprendizagem. Para o efeito, são apresentados os resultados da utilização do RED: Aula Digital - O Mundo da Carochinha 1.º Ano. O estudo foi concretizado numa turma do 1.° ano de escolaridade do 1.º CEB, constituída por 27 alunos, com idades e compreendidas entre os 6-7 anos, num Agrupamento de Escolas da Cidade de Castelo Branco, no âmbito da Prática de Ensino Supervisionada. Os resultados obtidos, após a análise e tratamento dos dados, permitiram concluir que ao utilizar este RED os alunos demonstraram terem adquirido os conteúdos abordados, pelo facto de se terem potenciado níveis de maior interesse, empenho, motivação, envolvimento e espírito de iniciativa no decorrer das atividades propostas. Porém, talvez pelo facto de serem alunos de 1º ano do 1º CEB, não descuram a presença e o acompanhamento da professora e a utilização de recursos em suporte papel. Quer isto dizer que deve haver uma complementaridade que concilie o fator humano (professora), com a utilização de recursos em suporte digital (RED) e recursos em suporte papel (Manual). Traduzindo, desta forma, uma rentabilização dos recursos pedagógicos conducentes a uma melhoria do processo de ensino e de aprendizagem.

O estudo foi concretizado numa turma do 1.º ano de escolaridade do 1.º CEB, constituída por 27 alunos, numa Escola EB1, onde se realizou a Prática de Ensino Supervisionada (PES), no âmbito do Mestrado em Educação Pré-Escolar e Ensino do 1.º CEB.. O objetivo da investigação pretendeu averiguar quais os potenciais contributos que a utilização complementar de um recurso em formato digital pode contribuir para melhorar a motivação e o envolvimento dos alunos no sentido de promover mais e melhores aprendizagens. Relativamente ao tipo de investigação, optou-se por uma metodologia de natureza qualitativa que recaiu numa investigação-ação. Como técnicas de recolha de dados foram utilizadas as notas de campo, a observação participante, a entrevista semiestruturada, o inquérito por questionário e os registos fotográficos. Nesta recolha de dados houve a participação direta dos alunos da turma, da Orientadora Cooperante, do «Par Pedagógico» e dos professores titulares de turma da Escola EB1 Quinta da Granja. Os resultados obtidos após a análise e tratamento dos dados, permitiram concluir que ao utilizar este RED os alunos demonstraram terem adquirido aprendizagens mais significativas, pelo facto de se terem potenciado níveis de maior interesse, empenho, motivação, envolvimento e espírito de iniciativa no decorrer das atividades propostas.

O presente relatório final de estágio do mestrado em educação pré-escolar e ensino do 1.º ciclo do ensino básico é composto por duas partes. A primeira consiste numa reflexão crítica sobre as Práticas de Ensino Supervisionadas (PES) desenvolvidas no estágio, tanto a nível da Educação Pré-Escolar (PES II) como do 1.º Ciclo do Ensino Básico (PES III), onde se analisam aspetos pedagógicos e didáticos e as competências essenciais aos profissionais, para a promoção de um ensino de qualidade, a partir das práticas realizadas. A segunda parte deste relatório incide sobre o trabalho de investigação desenvolvido. A questão abordada reflete acerca do potencial de uma mala pedagógica concebida para a promoção de situações de exploração da expressão dramática no âmbito da Educação Pré-Escolar. Este estudo enquadra-se numa investigação de natureza qualitativa de caráter exploratório. Utilizamos diversos instrumentos para auxiliar a recolha de dados, nomeadamente, a escala de envolvimento da criança de Laevers (1994), a grelha de observação da exploração dos objetos da mala pedagógica e entrevistas semiestruturadas às crianças e à educadora. A apresentação do estudo inclui enquadramento teórico e os resultados obtidos, dando-se a conhecer as conclusões. Tais resultados permitem entender que as sessões de exploração livre da mala pedagógica e dos objetos contribuíram eficazmente para promover interações entre crianças (sem influência de idade ou sexo) e desenvolver a criatividade e imaginação das mesmas. Ao longo deste trabalho é evidenciada a importância da expressão dramática na Educação Pré-Escolar. Ela coloca, desenvolve e desafia as capacidades de transformação e de imaginação das crianças mediante diversas situações. As malas são objetos simbólicos que potenciam oportunidades para essas capacidades se desenvolverem, criando diversas situações de exploração de jogos dramáticos, num espaço pedagógico, proporcionando momentos de aprendizagens significativas, bem como momentos prazerosos.

O presente relatório surgiu da nossa investigação e da nossa praxis tanto no contexto da Prática de Ensino Supervisionada em Educação Pré-Escolar, como em Ensino do 1º Ciclo do Ensino Básico, em instituições da cidade de Évora. O principal objetivo foi compreender a finalidade e funcionalidade atribuída pelas crianças à aprendizagem da leitura e da escrita. Neste sentido, foi construído um referencial teórico que sustentou todo o processo de investigação. Desta forma, considero fundamental, contextualizar de forma breve, os ambientes educativos e a conceção da ação educativa que regeu a minha prática. O presente relatório foi construído com base na investigação-ação, levando assim, à utilização de algumas técnicas e instrumentos de recolha de dados, de forma a atingir os objetivos propostos. Ao longo da investigação procurei promover o desenvolvimento da leitura e da escrita, por parte das crianças, no contexto educativo, bem como, promover uma exploração da língua portuguesa articulada com os diversos domínios curriculares. Os resultados que surgiram deste trabalho veem evidenciar que as crianças já apresentam diversos conhecimentos acerca do que é a leitura e a escrita, bem como a sua funcionalidade. Por outro lado, é notória a separação entre a educação pré-escolar e o 1º Ciclo do Ensino Básico, no sentido em que, no primeiro contexto, as crianças apresentam um papel central na aprendizagem, pois tudo é realizado com base nos seus interesses e necessidades, ao passo que, no segundo contexto, as atividades são planeadas para as crianças, mas elas não são participantes nesses processos. Assim, este relatório encontra-se organizado em quatro capítulos. O primeiro capítulo refere-se à fundamentação teórica que sustenta a investigação do tema. O segundo capítulo encontra-se relacionado com a conceção da ação educativa, na qual são apresentados os contextos onde desenvolvi a minha prática. No terceiro capítulo encontra-se a metodologia aplicada ao longo da PES, tendo por base a questão do educador/professor-investigador, bem como a análise, interpretação dos dados obtidos através da entrevista individual semiestruturada e respetivas conclusões. Por fim, no quarto capítulo tecerei implicações e investigações futuras acerca do estudo realizado; Supervised Teaching Practice in Pre-School Education and Teaching of the 1st Basic Education: Learning reading and writing in early childhood (from 3 to 10 years old) Abstract: This report emerged from our research and our praxis both in the context of Supervised Teaching Practice in Pre-School Education, as in teaching of the 1st Cycle of Basic Education in some institutions of the city of Évora. The main objective was to understand the purpose and function assigned by the learners to reading and writing. In this sense, a theoretical framework was created which underpinned the whole process of investigation. In this way, I consider fundamental to contextualize briefly the educational environments and the design of the educational action that conducted my practice. This report was built on the basis of research–action leading to the use of some techniques and tools for data collection in order to achieve the proposed objectives. Throughout the investigation I tried to promote the development of reading and writing by children in the educational context, as well as to promote an exploration of the Portuguese language in conjunction with the diverse curricular areas. The results that have emerged from this work prove that children have already a wide knowledge about what reading and writing are as well as its functionality. On the other hand, it is evident the separation of pre-school education from the first cycle of basic education in the sense that, in the first context, the children have a central role in learning, because everything is done based on their interests and needs, while in the second context activities are planned for the children, but they do not participate in those processes. Thus, this report is organized into four chapters. The first chapter refers to the theoretical background that supports research on the theme. The second chapter is related to the design of educational activity, which presents the contexts where I developed my practice. The third chapter presents the methodology applied along the PES based on the issue of educator/teacher-researcher, as well as the analysis, interpretation of data obtained through the individual semi-structured interview and the corresponding conclusions. Finally, in the fourth chapter I will discuss the implications and the future investigations about the study performed.

The aim of this study is to investigate the effectiveness of problem-based learning (PBL) on students’ mathematical performance. This includes mathematics achievement and students’ attitudes towards mathematics for third and eighth grade students in Saudi Arabia. Mathematics achievement includes, knowing, applying, and reasoning domains, while students’ attitudes towards mathematics covers, ‘Like learning mathematics’, ‘value mathematics’, and ‘a confidence to learn mathematics’. This study goes deeper to examine the interaction of a PBL teaching strategy, with trained face-to-face and self-directed learning teachers, on students’ performance (mathematics achievement and attitudes towards mathematics). It also examines the interaction between different ability levels of students (high and low levels) with a PBL teaching strategy (with trained face-to-face or self-directed learning teachers) on students’ performance. It draws upon findings and techniques of the TIMSS international benchmarking studies. Mixed methods are used to analyse the quasi-experimental study data. One -way ANOVA, Mixed ANOVA, and paired t-tests models are used to analyse quantitative data, while a semi-structured interview with teachers, and author’s observations are used to enrich understanding of PBL and mathematical performance. The findings show that the PBL teaching strategy significantly improves students’ knowledge application, and is better than the traditional teaching methods among third grade students. This improvement, however, occurred only with the trained face-to-face teacher’s group. Furthermore, there is robust evidence that using a PBL teaching strategy could raise significantly students’ liking of learning mathematics, and confidence to learn mathematics, more than traditional teaching methods among third grade students. Howe ver, there was no evidence that PBL could improve students’ performance (mathematics achievement and attitudes towards mathematics), more than traditional teaching methods, among eighth grade students. In 8th grade, the findings for low achieving students show significant improvement compared to high achieving students, whether PBL is applied or not. However, for 3th grade students, no significant difference in mathematical achievement between high and low achieving students was found. The results were not expected for high achieving students and this is also discussed. The implications of these findings for mathematics education in Saudi Arabia are considered.
