O projeto PmatE e a aprendizagem da matemática no ensino superior

O contexto educacional exige renovação de paradigmas. Impõem-se profundas alterações ao nível do papel e da função do professor e dos alunos, devendo-se privilegiar metodologias de aprendizagem ativas, cooperativas e participativas, rompendo-se com o ensino magistral e a mera transmissão de ‘conhecimentos’. As ferramentas informáticas poderão constituir-se uma mais-valia no contexto educativo, promovendo uma aprendizagem significativa e autorregulada pelo aluno, sempre sob a adequada orientação do professor. Neste contexto, foi criado, na Universidade de Aveiro, o Projeto Matemática Ensino (PmatE), com o principal objetivo de combater, de uma forma inovadora, as causas do insucesso escolar a matemática. No entanto, tal plataforma ainda não foi alvo de uma avaliação sistemática, nomeadamente ao nível do ensino superior, que nos permita concluir da consecução dos seus propósitos. Assim, a questão de investigação subjacente ao estudo em curso é - Qual o impacte da utilização diferenciada, como complemento à abordagem didáctica, da plataforma de ensino assistido (PEA) desenvolvida pelo PmatE na aprendizagem de temas matemáticos ao nível do Ensino Superior, principalmente ao nível da autonomia, da construção e aplicação de conhecimentos e do desenvolvimento de apetências pela Matemática. Para se tentar dar resposta à mesma, implementou-se um estudo misto, quantitativo e qualitativo, com alunos da unidade curricular Análise Matemática I do Curso Engenharia Alimentar de um Instituto Politécnico português, a quem se propôs uma exploração prévia da plataforma extra-aula para que, nesse espaço, se pudesse conceptualizar os conceitos envolvidos e realizar tarefas variadas quanto à sua natureza. Usaram-se como principais técnicas de recolha de dados a análise documental, a inquirição e a observação direta, suportadas pelos diversos instrumentos: Questionário Inicial e Final; testes de avaliação, nas versões pré-teste, pós-teste1 e pós-teste2; produções de uma bateria de tarefas de natureza diversificada; registo computorizado do percurso dos alunos relativamente ao trabalho por eles desenvolvido na plataforma do PmatE; notas de campo; dossier dos alunos e entrevistas. Os resultados obtidos, a partir de uma análise estatística dos dados quantitativos e de conteúdo dos dados qualitativos, indicam, por um lado, que os alunos mais autónomos, mais persistentes e que obtêm os melhores resultados são os alunos que usaram a plataforma com frequência e, por outro, que a utilização da plataforma contribuiu para aumentar o gosto pela Matemática. Este estudo permitiu, também, obter informação importante sobre aspetos que poderão melhorar a plataforma, em particular, relativos à natureza das tarefas e à resolução dos exercícios propostos.

The transformation of teachers: an adult learning approach

The study focused on the teacher as an adult learner rather than an instructor. A sample of three hundred and three elementary school teachers completed a two-part Likert survey questionnaire. The instrument was developed by the researcher in an attempt to operationalize Mezirow's Theory of Perspective Transformation. The four sub-scales collected information about teachers as they perceived themselves as adult learners and the way they conceptualize critical SelfReflection, Meaning perspectives and New Insights (Mezirow, 1978, 1981, 1989, 1990) within a framework of Mezirow's concept of Transformative Learning. Survey research methodology was used. Frequency distributions, means, and standard deviation were calculated. Reliability analysis and Pearson 'r' correlations established the internal consistency of items It Cross tabulations to describe differences in responses across demographic valuables were computed. The survey results indicated that teachers perceived themselves as self-directed learners. The findings support the need for a better understanding of the teacher as an adult learner so that teacher inservice programs and teacher supervision and evaluation can provide a viable learning alternative to the existing models used in practice.

An examination of the effects on learning seen in children afforded the opportunity to control the order of repetitions for three novel spatiotemporal sequences

Children were afforded the opportunity to control the order of repetitions for three novel spatiotemporal sequences. The following was predicted: a) children and adults in the self-regulated (SELF) groups would produce faster movement (MT) and reaction times (R T) and greater recall success (RS) during retention compared to the age-matched yoked (YOKE) groups; b) children would choose to switch sequences less often than adults; c) adults would produce faster MT and RT and greater RS than the children during acquisition and retention, independent of experimental group. During acquisition, no effects were seen for RS, however for MT and RT there was a main effect for age as well as block. During retention a main effect for practice condition was seen for RS and failed to reach statistical significance for MT and RT, thus partially supporting our first and second hypotheses. The third hypothesis was not supported.

An Examination of the Development of Online Higher Education in Canada and China: Keeping Pace and Making Space

This study examined the similarities and differences that currently exist between Chinese and Canadian online higher education, and explored the economic, political, and sociocultural environments that have shaped online education in these two jurisdictions. Furthermore, this paper discussed the efficacy of, and potential for, future development of online learning in higher education in both Canada and China. The research employed a collective case study design to gather information and data on the development of online higher education. The analysis on Contact North in Canada and the One-Man University in China provide a comparative perspective on the development of 2 typical online higher educational institutions in these two countries. The study revealed that the development of online higher education is influenced by the economic, political, and sociocultural factors of environment. Contact North and the One-Man University share similarities in many aspects, but are characteristically different. The Contact North can set an example for establishing and operating a self-regulated MOOCs platform. The study also generated implications for both organizations.

Prédiction des habiletés et habitudes de conduite automobile sécuritaire chez les conducteurs âgés : apport de la neuropsychologie clinique

L’insécurité routière chez les conducteurs âgés est attribuable en partie, aux effets délétères du vieillissement normal sur le fonctionnement cognitif. Les méthodes d’évaluation neuropsychologique par les tests ayant montré une certaine efficacité dans le cas du dépistage des habiletés de conduite chez les conducteurs âgés atteints d’affections neurologiques pathologiques, la présente thèse vise à évaluer la pertinence de cette approche chez les conducteurs vieillissants de la population générale. Le principal objectif de cette thèse est ainsi d’obtenir une vue d’ensemble sur le rôle et la sensibilité des mesures neuropsychologiques dans la prédiction des habiletés et habitudes de conduite automobile sécuritaire chez les conducteurs âgés. Dans la même perspective, la thèse explore d’autre part le rôle de variables sociodémographiques et psychologiques. L’article 1 évalue la validité prédictive de sept tests des fonctions visuo-attentionnelles et de la mémoire de travail en regard des habiletés de détection périphérique chez 50 conducteurs âgés de 62 à 83 ans. L’étude sur simulateur de conduite comprend une condition de conduite simple et une condition plus soutenue incluant une distraction téléphonique de type « mains-libres ». Selon les résultats, certains tests cognitifs prédisent bien les temps de détection. En outre, la validité prédictive des tests est plus importante dans la situation de conduite plus exigeante. Cela dit, les résultats de l’article 2 révèlent que le recours aux stratégies d’évitement des situations exigeantes est plus prononcé chez les individus qui présentent des faiblesses à certains des tests neuropsychologiques proposés. Les résultats indiquent en outre que l’utilisation des stratégies d’évitement routier est plus fréquente chez les conducteurs ayant tendance à déprécier leurs habiletés de conduite générales, à exprimer une moindre perception de contrôle ainsi qu’une attitude défavorable à l’endroit des situations de conduite complexes ou risquées. Les stratégies d’évitement se révèlent donc comme des réponses autorégulatrices proportionnelles aux limitations cognitives et aux perceptions individuelles. Dans les deux études, l’âge ne permet pas d’expliquer les différences individuelles, ceci ni en termes d’habiletés de détection périphérique ni de tendances autorégulatrices. Le rôle du genre est cependant plus nuancé. Ainsi, le principal apport de la présente thèse réside dans la constatation que si d’une part, certaines limitations neuropsychologiques sont associées à une réduction des habiletés de détection périphérique, ces mêmes limitations s’accompagnent aussi de mesures autorégulatrices qui peuvent contribuer à réduire le risque routier. Il appert conséquemment que les méthodes de dépistage de l’insécurité routière chez les conducteurs âgés se basant sur l’évaluation des limitations cognitives et attentionnelles doivent également rechercher et évaluer la teneur de leurs comportements routiers autorégulateurs. Dans le contexte de vieillissement de la population, des interventions pourront également miser sur le renforcement de ces comportements.

Antike und moderne Strategien der Texterschließung

Lateinische Schriftsteller im Original zu lesen, fällt vielen Schülerinnen und Schülern in der Lektürephase des Lateinunterrichts schwer. In der vorliegenden Dissertation wird untersucht, inwiefern gezielter Einsatz von Lernstrategien das Textverständnis verbessern kann. Strategisches Arbeiten mit Texten kann bereits zu einem sehr frühen Zeitpunkt in schriftbasierten Kulturen nachgewiesen werden. In dieser Arbeit werden Quellentexte aus der griechisch-römischen Antike und dem Mittelalter hinsichtlich texterschließender Strategien untersucht, systematisiert, kommentiert und im modernen Lateinunterricht eingesetzt. Dabei arbeiten die Schülerinnen und Schüler selbstgesteuert und forschend-entdeckend mit Reproduktionen antiker Papyri und Pergamente. Im Laufe des Unterrichtsprojektes, das ich CLAVIS, lat. für „Schlüssel“, nenne, lernen die Schüler im Zusammenhang mit Fachinhalten des Lateinunterrichts sechs antike Strategien der Texterschließung kennen. Diese Strategien werden heute noch genauso verwendet wie vor 2000 Jahren. Unter Berücksichtigung der Erkenntnisse der modernen Lernstrategieforschung wurden die Strategien ausgewählt, die als besonders effektive Maßnahmen zur Förderung von Textverständnis beurteilt werden, nämlich CONIUGATIO: Vorwissen aktivieren, LEGERE: mehrfaches und möglichst lautes Lesen, ACCIPERE: Hilfen annehmen, VERTERE: Übersetzen mit System, INTERROGARE: Fragen zulassen, SUMMA: Zusammenfassung erstellen. Ziel von CLAVIS ist es, Schülern ein Werkzeug zur systematischen Texterschließung an die Hand zu geben, das leicht zu merken ist und flexibel auf Texte jeder Art und jeder Sprache angewendet werden kann. Um die Effektivität des Unterrichtsprojektes CLAVIS zu überprüfen, wurde mit zwei parallel geführten 10. Klassen am Johann-Schöner-Gymnasium in Karlstadt im Schuljahr 2009/10 eine Vortest-Nachtest-Studie durchgeführt. Eine der Klassen wurde als Experimentalgruppe mit Intervention in Form von CLAVIS unterrichtet, die andere Klasse, die die Kontrollgruppe bildete, erhielt kein strategisches Training. Ein Fragebogen lieferte Informationen zur Vorgehensweise der Schüler bei der Textbearbeitung in Vortest und Nachtest (jeweils eine Übersetzung eines lateinischen Textes in identischem Schwierigkeitsgrad). Die Auswertung der Daten zeigte deutlich, dass Textverständnis und Übersetzungsfähigkeit sich bei denjenigen Schülern verbesserten, die die CLAVIS-Strategien im Nachtest angewendet hatten. Im Zusammenhang mit der Neugestaltung der Lehrpläne auf dem Hintergrund der Kompetenzorientierung ergeben sich für das Fach Latein neue Chancen, nicht nur inhaltlich wertvolle Zeugnisse der Antike zur allgemeinen, zweckfreien Persönlichkeitsbildung von Schülerinnen und Schülern einzusetzen, sondern gezielt Strategien zu vermitteln, die im Hinblick auf die in einer Informationsgesellschaft unverzichtbare Sprach- und Textkompetenz einen konkreten Nutzen haben.

Motivação e adesão ao exercício físico : um estudo sobre o papel dos treinadores pessoais

Introdução: Procuramos analisar a associação entre a frequência/adesão ao exercício físico (FAEF) em contexto de ginásios e health clubs (GHC) e os constructos previstos pela Teoria da Auto Determinação (TAD) em indivíduos que treinam com Treinador Pessoal (TP)e indivíduos que não treinam com TP. Método: Efetuámos uma revisão sistemática da literatura (RSL), seguida de um estudo observacional onde aplicámos questionários psicométricos para avaliar o clima da sessão de treino, resposta psicológica global, regulação motivacional, satisfação das necessidades psicológicas (NPB), escolha percebida sobre o desempenho em exercício. Foi controlada a FAEF durante 3 meses. A amostra consistiu em 88 clientes (Midade = 41.35, SD = 12.22, MIMC = 25.10, SD = 14.52) Resultados: Na RSL encontrámos 10 estudos, nenhum em contexto de TP. No nosso estudo não se registaram diferenças na FAEF, nem nas regulações motivacionais entre os grupos. No grupo com TP a competência associou-se à FAEF (p=.017) e a autonomia associou-se a menores níveis de mau estar psicológico e de fadiga (p=.032). O Clima de Tratamento do Programa não influenciou nenhum dos outcomes estudados. No grupo sem TP, quanto mais Autonomia (p=.038) e Motivação Intrínseca (p=.001) maior a FAEF. Regulações mais autodeterminadas estão associados a maiores valores de FAEF (p=.009). A motivação intrínseca associou-se positivamente (p=.014) com a FAEF em toda a amostra. Discussão: O suporte das NBP origina uma motivação mais auto regulada o que se reflete numa maior FAEF e bem estar psicológico. No grupo com TP a competência teve um maior contributo para a FAEF, no grupo sem TP a autonomia registou o valor mais elevado. Não se observaram diferenças entre os grupos na regulação motivacional e na FAEF. O suporte de autonomia dado pelo TP não apresentou resultados significativos na FAEF, o que contraria o esperado pela TAD. Estes dados são, por si só reveladores da importância de se aprofundar conhecimentos que auxiliem os TP’s a a motivarem com mais qualidade os seus alunos.

Maturation of limbic corticostriatal activation and connectivity associated with developmental changes in temporal discounting

Temporal discounting (TD) matures with age, alongside other markers of increased impulse control, and coherent, self-regulated behaviour. Discounting paradigms quantify the ability to refrain from preference of immediate rewards, in favour of delayed, larger rewards. As such, they measure temporal foresight and the ability to delay gratification, functions that develop slowly into adulthood. We investigated the neural maturation that accompanies the previously observed age-related behavioural changes in discounting, from early adolescence into mid-adulthood. We used functional magnetic resonance imaging of a hypothetical discounting task with monetary rewards delayed in the week to year range. We show that age-related reductions in choice impulsivity were associated with changes in activation in ventromedial prefrontal cortex (vmPFC), anterior cingulate cortex (ACC), ventral striatum (VS), insula, inferior temporal gyrus, and posterior parietal cortex. Limbic frontostriatal activation changes were specifically associated with age-dependent reductions in impulsive choice, as part of a more extensive network of brain areas showing age-related changes in activation, including dorsolateral PFC, inferior parietal cortex, and subcortical areas. The maturational pattern of functional connectivity included strengthening in activation coupling between ventromedial and dorsolateral PFC, parietal and insular cortices during selection of delayed alternatives, and between vmPFC and VS during selection of immediate alternatives. We conclude that maturational mechanisms within limbic frontostriatal circuitry underlie the observed post-pubertal reductions in impulsive choice with increasing age, and that this effect is dependent on increased activation coherence within a network of areas associated with discounting behaviour and inter-temporal decision-making.

The influence of environmental policy on the decisions of managers to adopt G-SCM practices

This article explores the reasons that affect the decisions of managers of firms to adopt management practices in order to green their supply chain management. Under the context of environmental policy, the relationship between policy instruments (‘command and control’, market-based, and self-regulated) and the decisions of managers to adopt green supply chain management (G-SCM) practices is examined. The results show that in some cases the environmental legislation, market-based instruments and self-regulated incentives could play a critical role in the decisions of managers to adopt some specific G-SCM practices, while in other cases environmental policy instruments have not seemed to affect the decisions of managers regarding some other G-SCM practices.

Rethinking a learning environment strategy

I have committed a significant period of time (in my case five years) to the purpose development of learning environments, with the belief that it would improve the self-actualisation and self-motivation of students and teachers alike. I consider it important to record and measure performance as we progressed toward such an outcome. Education researchers and practitioners alike, in the higher (university/tertiary) education systems, are seeking among new challenges to engage students and teachers in learning (James, 2001). However, studies to date show a confusing landscape littered with a multiplicity of interpretations and terms, successes and failures. As the discipline leader of the Information Technology, Systems and Multimedia (ITSM) Discipline, Swinburne University of Technology, Lilydale, I found myself struggling with this paradigm. I also found myself being torn between what presents as pragmatic student learning behaviour and the learner-centred teaching ideal reflected in the Swinburne Lilydale mission statement. The research reported in this folio reflects my theory and practice as discipline leader of the ITSM Discipline and the resulting learning environment evolution during the period 1997/8 to 2003. The study adds to the material evidence of extant research through firstly, a meta analysis of the learning environment implemented by the ITSM Discipline as recorded in peer reviewed and published papers; and secondly, a content analysis of student learning approaches, conducted on data reported from a survey of ‘learning skills inventory’ originally conducted by the ITSM Discipline staff in 2002. In 1997 information and communication technologies (ICT) were beginning to provide plausible means for electronic distribution of learning materials on a flexible and repeatable basis, and to provide answers to the imperative of learning materials distribution relating to an ITSM Discipline new course to begin in 1998. A very short time frame of three months was available prior to teaching the course. The ITSM Discipline learning environment development was an evolutionary process I began in 1997/8 initially from the requirement to publish print-based learning guide materials for the new ITSM Discipline subjects. Learning materials and student-to-teacher reciprocal communication would then be delivered and distributed online as virtual learning guides and virtual lectures, over distance as well as maintaining classroom-based instruction design. Virtual here is used to describe the use of ICT and Internet-based approaches. No longer would it be necessary for students to attend classes simply to access lecture content, or fear missing out on vital information. Assumptions I made as discipline leader for the ITSM Discipline included, firstly, that learning should be an active enterprise for the students, teachers and society; secondly, that each student comes to a learning environment with different learning expectations, learning skills and learning styles; and thirdly, that the provision of a holistic learning environment would encourage students to be self-actualising and self-motivated. Considerable reading of research and publications, as outlined in this folio, supported the update of these assumptions relative to teaching and learning. ITSM Discipline staff were required to quickly and naturally change their teaching styles and communication of values to engage with the emergent ITSM Discipline learning environment and pedagogy, and each new teaching situation. From a student perspective such assumptions meant students needed to move from reliance upon teaching and prescriptive transmission of information to a self-motivated and more self-actualising and reflective set of strategies for learning. In constructing this folio, after the introductory chaperts, there are two distinct component parts; • firstly, a Descriptive Meta analysis (Chapter Three) that draws together several of my peer reviewed professional writings and observations that document the progression of the ITSM Discipline learning environment evolution during the period 1997/8 to 2003. As the learning environment designer and discipline leader, my observations and published papers provide insight into the considerations that are required when providing an active, flexible and multi-modal learning environment for students and teachers; and • secondly, a Dissertation (Chapter Four), as a content analysis of a learning skills inventory data collection, collected by the ITSM Discipline in the 2002 Swinburne Lilydale academic year, where students were encouraged to complete reflective journal entries via the ITSM Discipline virtual learning guide subject web-site. That data collection included all students in a majority of subjects supported by the ITSM Discipline for both semesters one and two 2002. The original purpose of the journal entries was to have students reflectively involved in assessing their learning skills and approaches to learning. Such perceptions were tested using a well-known metric, the ‘learning skills inventory’ (Knowles, 1975), augmented with a short reflective learning approach narrative. The journal entries were used by teaching staff originally and then made available to researchers as a desensitised data in 2003 for statistical and content analysis relative to student learning skills and approaches. The findings of my research support a view of the student and teacher enculturation as utilitarian, dependent and pragmatically self-motivated. This, I argue, shows little sign of abatement in the early part of the 21st Century. My observation suggests that this is also independent of the pedagogical and educational philosophy debate or practice as currently presented. As much as the self-actualising, self-motivated learning environment can be justified philosophically, the findings observed from this research, reported in this folio, cannot. Part of the reason for this originates from the debate by educational researchers as to the relative merits of liberal and vocational philosophies for education combined with the recent introduction of information and communication technologies, and commodification of higher education. Challenging students to be participative and active learners, as proposed by educationalists Meyers and Jones (1993), i.e. self-motivated and self-actualising learners, has proved to be problematic. This, I will argue, will require a change to a variable/s (not yet identified) of higher education enculturation on multiple fronts, by students, teachers and society in order to bridge the gap. This research indicates that tertiary educators and educational researchers should stop thinking simplistically of constructivist and/or technology-enabled approaches, students learning choices and teachers teaching choices. Based on my research I argue for a far more holistic set of explanations of student and staff expectations and behaviour, and therefore pedagogy that supports those expectations.

Concepts and factors influencing independent learning in IS higher education

The concepts of independent learning (IL), self-directed learning (SDL) and self-regulated learning (SRL) have been widely used in relation to students’ learning success. Often, these terms are interrelated and used interchangeably in the literature with regards to students’ learning process. The purpose of this paper is (1) to promote conceptual clarity by having clear definitions of SRL, SDL and IL and (2) to provide a review of research related to the development of students’ SRL at higher education particularly in the context of Information Systems studies. The findings from the literature reveal that mastering the process self-regulation progressively leads to self-directed and independent learning. The literature review on SRL reveals that students’ academic self-regulation is influenced by their personal processes such as cognitive knowledge and motivational beliefs and also external processes such as lecturers and instructions in higher education.
