The impact of an online mathematics education project (MATACTIVA) on higher education students

The Online Mathematics Education Project (MatActiva) is an exciting new initiative which aims to support and enhance mathematics education. The project is led by the Institute of Accounting and Administration of Porto (ISCAP), part of the Polytechnic Institute of Porto (IPP). It provides innovative resources and carefully constructed materials around themes such as Elementary Mathematics, Calculus, Algebra, Statistics and Financial Mathematics to help support and inspire students and teachers of mathematics. The goal is to increase mathematical understanding, confidence and enjoyment, enrich the mathematical experience of each person, and promote creative and imaginative approaches to mathematics. Furthermore the project can be used to deliver engaging and effective mathematics instruction through the flipped classroom model. This paper also presents the findings of a large survey, whose propose was to study the student’s reaction to the project.

O doente com patologia múltipla em medicina geral e familiar: comorbilidade de 4 doenças crónicas

RESUMO: A tese de doutoramento visa demonstrar duas proposições: a comorbilidade de 4 situações de doença prevalentes, hipertensão arterial (HTA), diabetes (DM), doença cardíaca isquémica (DCI) e asma é um assunto importante em Medicina Geral e Familiar e o seu estudo tem diversas implicações na forma como os cuidados de saúde são prestados, na sua organização e no ensino-aprendizagem da disciplina. O documento encontra-se dividido em 4 partes: 1) justificação do interesse do tema e finalidades da dissertação; 2) revisão sistemática de literatura publicada entre 1992 e 2002; 3) apresentação de dois trabalhos de investigação, descritivos e exploratórios que se debruçam sobre a mesma população de estudo, o primeiro intitulado “Comorbilidade de quatro doenças crónicas e sua relação com factores sócio demográficos” e o segundo, “Diferenças entre doentes, por médico e por sub-região, na comorbilidade de 4 doenças crónicas”; 4) conclusões e implicações dos resultados dos estudos na gestão da prática clínica, nos serviços, no ensino da disciplina da MGF e no desenvolvimento posterior de uma linha de investigação nesta área. O primeiro estudo tem como objectivos: descrever a prevalência da comorbilidade entre as 4 doenças-índice; verificar se existe relação entre o tempo da primeira doença e o tempo decorrido até ao aparecimento da 2ª e da 3ª doença, nas 4 doenças; determinar a comorbilidade associada às 4 doenças; identificar eventuais agrupamentos de doenças e verificar se existe relação entre comorbilidade e factores sociais e demográficos. O segundo estudo pretende verificar se existem diferenças na comorbilidade a nível local, por médico, e por Sub-Região de Saúde. O trabalho empírico é descritivo e exploratório. A população é constituída pelos doentes, com pelo menos uma das 4 doenças crónicas índice, das listas de utentes de 12 Médicos de Família a trabalharem em Centros de Saúde urbanos, suburbanos e rurais dos distritos de Lisboa e Beja. Os dados foram colhidos durante um ano através dos registos médicos. As variáveis sócio demográficas estudadas são: sexo, idade, etnia/raça, escolaridade, situação profissional, estado civil, tipo de família, funcionalidade familiar, condições de habitação. A comorbilidade é definida pela presença de duas ou mais doenças e estudada pelo número de doenças coexistentes. O tempo de duração da doença é definido como o número de anos decorridos entre o ano de diagnóstico e 2003. Os problemas de saúde crónicos são classificados pela ICPC2. Nas comparações efectuadas aplicaram-se os testes de Mann-Whitney e de Friedman, de homogeneidade e de análise de resíduos. A Análise Classificatória Hierárquica foi utilizada para determinar o agrupamento de doenças e a Análise de Regressão Categórica e Análise de Correspondências na relação entre as características sócio demográficas e a comorbilidade. Identificaram-se 3998 doentes. A idade média é de 64,3 anos (DP=15,70). Há uma correlação positiva significativa (r =0,350 r=0) entre “anos com a primeira doença”e “idade dos doentes” em todos os indivíduos (homens r=0,129 mulheres r=0,231). A comorbilidade entre as quatro doenças crónicas índice está presente em 1/3 da população. As associações mais prevalentes são HTA+DM (14,3%) e HTA+DCI (6,25%). Existe correlação positiva, expressiva, entre a duração da primeira doença, quando esta é a HTA ou a DM, e o intervalo de tempo até ao aparecimento da 2ª e da 3ª doenças. Identificaram-se 18 655 problemas crónicos de saúde que se traduziram em 244 códigos da ICPC2. O número médio de problemas foi de 5,94 (DP=3,04). A idade, a actividade profissional, a funcionalidade familiar e a escolaridade foram as variáveis que mais contribuíram para diferenciar os indivíduos quanto à comorbilidade. Foram encontradas diferenças significativas entre médicos(c2=1165,368 r=0) e entre os agrupamentos de doentes por Sub-Região de Saúde (c2= 157,108 r=0) no respeitante à comorbilidade. Na partição por Lisboa o número médio de problemas é de 6,45 e em Beja de 5,35. Deste trabalho ressaltam várias consequências para os profissionais, para os serviços, para o ensino e para a procura de mais saber nesta área. Os médicos, numa gestão eficiente de cuidados são chamados a desempenhar um papel de gestores da complexidade e de coordenadores assim como a trabalhar num modelo organizativo apoiado numa colaboração em equipa. Por sua vez os serviços de saúde têm que desenvolver medidas de avaliação de cuidados que integrem a comorbilidade como medida de risco. O contexto social da cronicidade e da comorbilidade deverá ser incluído como área de ensino. A concluir analisa-se o impacto do estudo nos colaboradores e o possível desenvolvimento da investigação nesta área.----------------------------------------ABSTRACT: The PhD Thesis has two propositions, co-morbidity of four chronic conditions (hypertension, asthma, diabetes, cardiac ischaemic disease) is a prevalent and complex issue and its study has several implications in the way care is provided and organised as well as in the learning and teaching of the discipline of General Practice. In the first part of the document arguments of different nature are given in order to sustain the dissertation aims; the second part describes a systematic study of literature review from 1992 to 2002; the third presents two research studies "Comorbidity of four chronic diseases and its relation with socio demographic factors” and “Differences between patients among GPs at local and regional level”; implications of study results for practice management, teaching and research are presented in the last part. The prevalence of the four chronic diseases co-morbidity, the relation of the first disease duration with the time of diagnose of the next index condition, the burden of co-morbidity in the four chronic diseases, the clustering of those diseases, the relation between demographic and social characteristics and co-morbidity, are the objectives of the first study. The second intends to verify differences in comorbidity between patients at local and regional level of practice. Research studies were descriptive and exploratory. The population under study were patients enlisted in 12 GPs working in urban and rural health centres, in Lisbon and Beja districts, with at least one of the four mentioned diseases. Data were collected through medical records during one year (2003) and 3998 patients were identified. The social demographic variables were: sex, age, ethnicity/race, education, profession, marriage status, family status, family functionality, home living conditions. Co-morbidity is defined by the presence of two or more diseases, and studied by the number of co-existing diseases. The time duration of the disease is defined by the number of years between the diagnostic year and 2003. The chronic disease problems are classified in accord with ICPC2. The characterization of population is descriptive. The effected comparisons applied the Mann-Whitney, Friedman, homogeneity and analysis of residuals tests. The Classificatory Hierarchy Analysis was utilized to determine the grouping of diseases and the Regression Categorization and Correspondences Analysis was used to study the relation of socio-demographic and co-morbidity. The median age of the population under study is 64,3 (SD= 15,70). There is a significant positive correlation (r =0,350 r=0)between “years with the first disease” and “patient age” for all individuals (men r=0,129 women r=0,231). Co-morbidity of the four index diseases is present in 1/3 of the studied population. The most prevalent associations for the four diseases are HTA+DM (14,03%) and HTA+IHD (6,25%). Expressive positive correlation between the duration of the first disease and the second and the third index disease interval is found. For the 3988 patients, 18 655 chronic health problems, translated in 244 ICPC2 codes, were identified. The mean number of problems is 5,94 (SD=3,04). Age, professional activity, family functionality and education level are the socio demographic characteristics that most contribute to differentiate individuals concerning the overall co-morbidity. Significant differences in co-morbidity between GP patients at local (c2=1165,368 r=0) and regional level (c2= 157,108 r=0) are found. This study has several consequences for professionals, for services, for the teaching and learning of General Practice and for the pursuit of knowledge in this area. New competences and performances have to be implemented. General Practitioners, assuming a role of co-ordination, have to perform the role of complexity managers in patient's care, working in practices supported by a strong team in collaboration with other specialists. In order to assess provided care, services have to develop tools where co-morbidity is included as a risk measure. The social context of comorbidity and chronicity has to be included in the curricula of General Practice learning and teaching areas. The dissertation ends describing the added value to participant's performance for their participation in the research and an agenda for further research, in this area, based on a community of practice.--------RÉSUMÉ:Cette thèse de doctorat prétend démontrer deux postulats : le premier, que la comorbidité de quatre maladies fréquentes, hypertension artérielle (HTA), diabète (DM), maladie cardiaque ischémique (DCI) et asthme, est un thème important en Médecine Générale et Familiale et que son étude a plusieurs implications au niveau de l'approche pour dispenser les soins, de leur organisation et de l'enseignement/apprentissage de la discipline. Le document comprend quatre parties distinctes : 1) justification de l'intérêt du sujet et objectifs de la dissertation ; 2) étude systématique de publications éditées entre 1992 et 2002 ; 3) présentation de deux travaux de recherche, descriptifs et exploratoires, un premier intitulée « Comorbidité de quatre maladies chroniques et leur relation avec des facteurs sociodémographiques » et un deuxième « Différences entre malades, selon le médecin et la sous région, dans la comorbilité de quatre maladies chroniques» ; 4) conclusions et conséquences des résultats des études dans la gestion de la pratique clinique, dans les services, dans l'enseignement de la discipline de MGF et dans le développement postérieur de la recherche dans ce domaine. Les objectifs de la première étude sont les suivants : décrire la prévalence de la comorbidité entre les quatre maladies chroniques, vérifier s'il existe une relation entre temps de durée de la première maladie et l'espace de temps jusqu'à le diagnostic de la 2ème ou 3ème maladie; déterminer la comorbidité entre les 4 maladies ; identifier d'éventuelles groupements de maladies et vérifier s'il existe une relation entre comorbidité et facteurs sociodémographiques. La deuxième étude prétend vérifier s'il existe des différences de comorbidité entre médecins et par groupement régional. Le travail empirique est descriptif et exploratoire. La population est composée des malades ayant au moins une des quatre maladies chroniques parmi les listes de malades de douze Médecins de Famille qui travaillent dans des Centres de Santé urbains, suburbains et ruraux (Districts de Lisbonne et Beja). Les données ont été extraites pendant l'année 2003 des registres des médecins. Les variables sociodémographiques étudiées sont : le sexe, l'âge, l'ethnie/race, la scolarité, la situation professionnelle, l'état civil, le type de famille, sa fonctionnalité, les conditions de logement. La comorbidité est définie lorsqu'il existe deux ou plusieurs maladies et est étudiée d'après le nombre de maladies coexistantes. La durée de la maladie est établie en comptant le nombre d'années écoulées entre le diagnostique et 2003. Les problèmes de santé chroniques sont classés par l'ICPC 2. Pour les comparaisons les tests de Mann-Whitney et Friedman, de homogénéité et analyse de résidues ont été appliqués. L'Analyse de Classification Hiérarchique a été utilisée pour procéder au regroupement des maladies et l'Analyse de Régression Catégorique et l'Analyse de Correspondances pour étudier la relation entre les caractéristiques sociodémographiques et la comorbilité. Les principaux résultats sont les suivants : les 3998 malades identifiés ont 64,3 ans d'âge moyen (DP=15,70). Il existe une corrélation positive significative (r =0,350 r=0) entre « les années avec la première maladie » et « l'âge des malades », chez tous les individus (hommes r=0,129 femmes r=0,231). La comorbidité entre les quatre maladies chroniques est une réalité chez 1/3 des patients. Les associations les plus fréquentes sont HTA+DM (14%) et HTA+DCI (6,25%). Il existe une corrélation positive significative entre la durée de la première maladie, HTA ou DM, et l'écart jusqu'à l'apparition de la deuxième et de la troisième maladie. Chez les malades, 18.655 problèmes chroniques de santé ont été identifiés et traduits en 244 codes de l'ICPC2. La moyenne des problèmes a été de 5,94 (DP=3,04). L'âge, l'activité professionnelle, la fonctionnalité familiale et la scolarité sont les variables qui ont le plus contribué à différencier les individus face à la comorbilité. Des différences notoires ont été trouvées entre médecins (c2=1165,368 r=0) et entre les groupements régionaux (c2=157,108 r=0) en ce qui concerne la comorbidité. Dans le groupe de patients de Lisbonne, le chiffre moyen de problèmes est de 6,45 et à Beja il est de 5,35. Cette étude met en évidence plusieurs conséquences pour les professionnels, les services, l'enseignement et l'élargissement du savoir dans ce domaine. Les médecins, soucieux de gérer efficacement les soins sont appelés à jouer un rôle de gestionnaires de la complexité et de coordinateurs, de même qu'à travailler dans un modèle d'organisation soutenus par un travail d'équipe. D'autre part, les services de santé doivent eux aussi développer des mesures d'évaluation des soins qui intègrent la comorbidité comme mesure de risque. Le contexte social de la chronicité et de la comorbidité devra être inclus comme domaines à étudier. La fin de cette thèse décrit l'impact de cette étude sur les collaborateurs et le développement futur de la recherche dans ce domaine.

Digital storytelling: student ID in higher education

Identity achievement is related to personality, as well as cognitive and interpersonal development. In tandem with the deep structural changes that have taken place in society, education must also shift towards a teaching approach focused on learning and the overall development of the student. The integration of technology may be the drive to foster the needed changes. We draw on the literature of multiple subject areas as basis for our work, namely: identity construction and self-representation, within a psychological and social standpoint; Higher Education (HE) in Portugal after Bologna, college student development and other intrinsic relationships, namely the role of emotions and interpersonal relationships in the learning process; the technological evolution of storytelling towards Digital Storytelling (DS) – the Californian model – and its connections to identity and education. Ultimately we propose DS as the aggregator capable of humanizing HE while developing essential skills and competences. Grounded on an interpretative/constructivist paradigm, we implemented a qualitative case study to explore DS in HE. In three attempts to collect student data, we gathered detailed observation notes from two Story Circles; twelve student written reflections; fourteen Digital Stories and detailed observation notes from one Story Show. We carried out three focus groups with teachers where we discussed their perceptions of each student prior to and after watching the Digital Stories, in addition to their opinion on DS in HE as a teaching and learning method and its influence on interpersonal relationships. We sought understandings of the integration of DS to analyze student selfperception and self-representation in HE contexts and intersected our findings with teachers’ perceptions of their students. We compared teachers’ and students’ perspectives, through the analysis of data collected throughout the DS process – Story Circle, Story Creation and Story Show – and triangulated that information with the students’ personal reflections and teacher perceptions. Finally we questioned if and how DS may influence teachers’ perceptions of students. We found participants to be the ultimate gatekeepers in our study. Very few students and teachers voluntarily came forth to take part in the study, confirming the challenge remains in getting participants to see the value and understand the academic rigor of DS. Despite this reluctance, DS proved to be an asset for teachers and students directly and indirectly involved in the study. DS challenges HE contexts, namely teacher established perception of students; student’s own expectations regarding learning in HE; the emotional realm, the private vs. public dichotomy and the shift in educational roles.

Education through theater equal opportunity project being a girl being a boy

Dramatic narratives give emphasis to the process of storytelling of daily life. The script or story is constructed as a dialogue between actors. The words acquire a signification through a dynamic process of communication, where narratives are written not with a pencil but with the body, not written with the mind but with anima. In this paper we present a phenomenological analysis of an experience conducted in a middle grade school of Italy with the proposal to analyze how boys and girls see themselves and the opposite gender and how they perceive the equal opportunity between female and masculine roles.

Standard commercial education robotic platform: intermediate solution to teaching robotics

Teaching robotics to students at the beginning of their studies has become a huge challenge. Simulation environments can be an effective solution to that challenge where students can interact with simulated robots and have the first contact with robotic constraints. From our previous experience with simulation environments it was possible to observe that students with lower background knowledge in robotics where able to deal with a limited number of constraints, implement a simulated robotic platform and study several sensors. The question is: after this first phase what should be the best approach? Should the student start developing their own hardware? Hardware development is a very important part of an engineer's education but it can also be a difficult phase that could lead to discouragement and loss of motivation in some students. Considering the previous constraints and first year engineering students’ high abandonment rate it is important to develop teaching strategies to deal with this problem in a feasible way. The solution that we propose is the integration of a low-cost standard robotic platform WowWee Rovio as an intermediate solution between the simulation phase and the stage where the students can develop their own robots. This approach will allow the students to keep working in robotic areas such as: cooperative behaviour, perception, navigation and data fusion. The propose approach proved to be a motivation step not only for the students but also for the teachers. Students and teachers were able to reach an agreement between the level of demand imposed by the teachers and satisfaction/motivation of the students.

Gender differences in internet usage habits: a case study in higher education

The usage of information and communication technologies has been growing among students and teachers. In order to improve the use of the Internet as a tool to support teaching and learning it is necessary to understand the Internet usage habits of students. Thus, a study was conducted with 1397 students from five schools of the Polytechnic of Porto. The data was collected through an online questionnaire abd was analized by age range, gender and scientific field. In this paper,gender differences are analyzed and presented in 3 dimensions: type of Internet usage, communication tools and the role of the Internet tools in education.

Differences in internet and LMS usage: a case study in higher education

The Internet plays an important role in higher education institutions where Learning Management Systems (LMS) occupies a main role in the eLearning realm. In this chapter we aim to characterize the Internet and LMS usage patterns and their role in the largest Portuguese Polytechnic Institute. The usage patterns were analyzed in two components: characterization of Internet usage and the role of Internet and LMS in education. Using a quantitative approach, the data analysis describes the differences between gender, age and scientific fields. The carried qualitative analysis allows a better understanding of students’ both motivations, opinions and suggestions of improvement. The outcome of this work is the presentation of the Portuguese students’ profile regarding Internet and LMS usage patterns. We expect that these results can be used to select the most suitable digital pedagogical processes and tools to be adopted regarding the learning process and most adequate LMS’s policies.

The importance of physical education classes in pre-school children

The purpose of this study was to analyse differences between total physical activity (TPA) and moderate-to-vigorous PA (MVPA) of pre-school children during daily school hours when they attended the physical education class (PED) and school days without PE class (NPED) and to assess the contribution of PE classes to TPA in school hours. The sample was composed of 193 pre-school healthy children (96 girls) aged from three to five years old and was conducted between February and December of 2008. Children wore accelerometers for at least four consecutive days during school hours. Data were analysed with specific software, age-specific counts-per-minute cut-off points and a 5 s epoch were used. Independent and general linear model repeated measures were used to assess differences between gender and differences between different days within each gender, respectively. Boys engaged more MVPA than girls (P < 0.05). During PED, pre-school children engaged significantly more in TPA and MVPA than during NPED (P < 0.05). PE class contributed, on average, 27.7% for the TPA and 32.8% of daily MVPA during PED in both gender. The results of this study suggest that structured PA such as a PE class increased the daily TPA and MVPA level of pre-school children.

HIV Voluntary Testing among Portuguese Women Attending Family Planning Clinics: Implications for HIV Prevention Education and Testing

Objectives: The aim of this article is to analyze the factors associated with HIV testing among 767 sexually active women. Methods: Participants were administered several self-report questionnaires that assessed behavioral and psychosocial measures. Results: Overall, 59.8% of the participants reported ever having tested for HIV. Results show that higher levels of education, being pregnant or having been pregnant, concern about AIDS, AIDS knowledge, self-efficacy in condom negotiation and perception of no risk in partner significantly predicted the likelihood of testing among women. Attending the mass was negatively associated with HIV testing. Conclusions: These findings provide information that can be used in the development of a focused gender sensitive HIV prevention program to increase HIV testing.

HRM higher education in Europe

Higher education has earned in the recent years an increasing attention in Europe. European Higher Education Area (EHEA) is being developed, a three-cycle qualifications structure is formally in place, the principles of quality assurance are agreed, and a range of mobility instruments is being created. A European Qualifications Framework (EQF) is established (2008), and national qualifications frameworks in Europe should be all be published this year. In the HRM field, higher education is remaining largely unexamined. It is undertheorised and with lack of empirical research, especially if we consider the European reality. With the exception of Brewster et al. (2000) and Boxall et al. (2007), all the research published on the specific HRM higher education field seems to be American (Barber, 1999; Chadwick, 2005; Hayton et al.,2005; Kaufman, 1996, 1999; Langbert, 2005, 2000; Sincoff & Owen, 2004; Van Eyden et al., 1997; Wimbush 2008). This study analyses HRM higher education in Europe with the aim to identify the current trends of European HRM academic qualifications system. In order to provide strategic indicators on the subject, research was carried out in 14 European countries. The sample was constituted by the three cycles defined in Bergen (bachelor, master and PhD) and the primary information source was the Portal on Learning Opportunities throughout the European Space promoted by the European Commission (PLOTEUS). Within a qualitative methodology, qualifications’ structures, approaches, and competencies are explored as main analytical categories.
