Patterns in the first school years: main constraints
Authors suggest that several mathematical patterns must be addressed, in a systematic way, since an early age, given their key role in the development of algebraic thinking, amongst other aspects. Following this perspective, we developed several activities focusing on patterns of various kinds, involving children from 3 years of age. These activities revealed a set of tasks which are extremely complex and difficult for children. In this paper, by focusing on the pupils’ own productions, we will discuss some of above-mentioned didactic proposals and the implication of the results
Online Scientific Volunteering: the technological immersion for the co-construction of knowledge, employability, entrepreneurship and innovation in a logic of inclusion
“We all have something to learn and something to share” is the motto of this project, through which we aim to assess the impact of a multilingual platform which combines and makes the most of the potentials of digital environments and favours inclusion, in the co-construction of knowledge in learning/practice, in employability, entrepreneurism and innovation. In this article we will introduce an ongoing project which is founded on the principle of openness to the research community. Its philosophy is Online Scientific Volunteering for the co-construction of knowledge about learning best practices. The platform that will emerge from the project will be open access. The academic community, whether national or international, can contribute with content and knowledge to the platform, through interaction and discussions around relevant and emerging topics. The community may also exploit, without encumbrance, the contents of the platform for their own benefit. This way students and scientific expertise can share in a common knowledge space, and together build a comprehensive knowledge base.info:eu-repo/semantics/publishedVersio
La organización escolar y la movilización de los profesores y estudiantes en el uso de un nuevo Plan de Estudios de la Educación Secundaria General en Timor Oriental
Given that reforms involving how to deal with the past are extremely difficult, especially when the past involves memories of victimization, death, and destruction so widespread that a high percentage of the population is affected, the main purpose of this article is to describe how the general secondary education (GSE) curriculum in East Timor – an ancient Portuguese colony – is organized in terms of principles and objectives, themes, and methodological guidelines that give priority to assisting students to minimize or manage problems associated with conflict. Subsequently, the current state of GSE is characterized, in terms of school organization and logistics, and mobilization of teachers and students in using the new curriculum. The empirical results show that curricular materials incorporate aspects that can contribute to understanding and minimizing or managing problems created by the conflict, as well as contributing to avoid new conflicts. Nevertheless, although textbooks incorporate these aspects and teachers and students express interest in use them, problems remain regarding their appropriate usage due to numerous factors such as: logistics; school organization and poor teacher skills, despite training given and continued focused investment.Las reformas que
implican lidiar con el pasado son extremadamente difíciles, especialmente cuando implican recuerdos de
víctimas, muerte y destrucción tan generalizados que un alto
porcentaje de la población se ve afectada. En ese sentido, el
propósito principal de este a
rtículo es describir cómo el Plan
General de Estudios de Educación Secundaria (GSE) en Timor
Oriental
–
una antigua colonia portuguesa
–
se organiza en términos de principios, objetivos, temas y orientaciones metodológicas que dan prioridad a la formación de
los estudiantes para
minimizar o controlar los problemas asociados con el conflicto.
Por tanto, el estado actual de GSE se caracteriza por el uso del
nuevo plan de estudios, en términos de organización escolar,
logística, y de movilización de profesores y
estudiantes. Los
resultados empíricos muestran que los materiales curriculares
incorporan aspectos que pueden contribuir a comprender y
minimizar o controlar los problemas creados por el conflicto, así
como para contribuir a evitar nuevos conflictos. Sin
embargo,
aunque los libros de texto incorporan estos aspectos y los profesores y los estudiantes expresan interés en el uso de ellos, hay
problemas relativos a su utilización adecuada debido a numerosos factores, tales como: logística; la organización escolar y la
mala preparación que todavía tienen los profesores, a pesar de la
formación que se les ha brindado
The transfer of safety training: unveiling the role of OHS trainers
The main goal of this thesis is to provide a contribution to the knowledge of the role played
by OHS professionals in the transfer of the safety training they prepare and deliver in
organizations as in-house trainers, in the context of their overall activity. The influences of other
environmental and individual factors unexplored in the study of the transfer process are also
examined. The present thesis is divided in five chapters that comprehend a review of literature
about professional training and safety training, mainly focusing on the transfer problematic and
the factors that affect it (Chapters 1 and 2), and three empirical studies that analyze different
angles of the same phenomenon (Chapters 3, 4 and 5). The importance of the safety training
transfer problematic is enhanced as well as the factors that may determine the success of
interventions. From a theoretical point of view, the present work provides several major
contributions, in particular: it unveils how OHS professionals, through their safety-related
interactions with employees’ in the work environment, can influence the transfer of safety
training and how they perceive their role in the process; it reveals the effect of felt-responsibility
in the transfer process, as a psychological mechanism that affect both the trainers’ support
toward transfer and the trainees’ effort to apply the safety training in-the-job. Regarding the
practical contributions, this thesis suggests important strategies to the training design and
management in organizations that can improve the safety training success.A presente tese tem como principal finalidade contribuir para o conhecimento sobre o papel
desempenhado pelos profissionais de SST na transferência da formação que preparam e
ministram aos trabalhadores, no âmbito do seu trabalho nas organizações. São ainda analisadas
influências de fatores ambientais e individuais no processo de transferência ainda inexploradas
pela investigação. Para o efeito estruturámos a tese em cinco capítulos que incluem: uma revisão
da literatura sobre a formação profissional, em geral e no domínio específico da saúde e
segurança no trabalho, com particular enfoque na problemática da transferência da formação e
dos fatores que a afetam (capítulos 1 e 2); três estudos empíricos que analisam diferentes
dimensões do mesmo fenómeno (capítulos 3, 4 e 5). A importância do tópico da transferência
da formação em saúde e segurança no trabalho é realçada tal como a dos fatores que determinam
o sucesso das intervenções. De um ponto de vista teórico, a tese proporciona como principais
contributos: um conhecimento sobre como os profissionais de SST podem influenciar, através
das interações que estabelecem com os trabalhadores, no âmbito do sistema de gestão da SST
das organizações, a utilização das aprendizagens realizadas na formação; revela o efeito do
sentido de responsabilidade no processo de transferência, enquanto mecanismo psicológico que
afeta tanto o apoio prestado pelo profissional de SST à transferência como o esforço dos
formandos em aplicar no trabalho os adquiridos na formação. No que respeita aos contributos
práticos, a tese sugere importantes estratégias para o desenho e gestão das intervenções
formativas em saúde e segurança no trabalho nas organizações
Enhancing physical activity coaching through personalized motivational strategies and self-adaptive goal-setting: development of self-adaptive processes in a monitoring and coaching smartphone application
Dissertação para obtenção do Grau de Mestre em Engenharia BiomédicaThe rising age of the European population brings increased costs in healthcare mainly related to the management of chronic diseases. Regular physical activity has been shown to help in the prevention and control of disease risk. Mobile phones have provided promising and emergent ways of promoting healthy lifestyles, allowing real-time monitoring and coaching to be delivered at any time and any place. The presented work adds new features to the Activity Coach, an ambulatory feedback system that aims to encourage physical activity. The Integral of the Modulus of Body Acceleration (IMA) is the unit used as an estimate for energy expenditure. Although previous research demonstrated the potential of this system, results also showed that adherence drops after a few weeks. The primary goal of this research was to design, implement, and test adaptive goal-setting and personalized feedback strategies in order to encourage physical activity. Regarding the self-adaptive goal-setting feature, the goal for each day is defined automatically based on the physical activity performed at that day of the week since the beginning of the intervention. Hence, the intention is to help the user to increase or maintain his level of physical activity taking his daily routine as a reference. The second element added to the system regards motivational feedback messages, a key factor in interventions aiming at behavior change. Based on the levels of self-efficacy, stage-of-change, and daily activity, the user is assigned to one of the six pre-defined feedback strategies in the system. The content of the motivational cues depends on the selected feedback strategy.
The evaluation of the system focused on providing better understandable and more accurate feedback to the user. To do so, we evaluated the challenge and attainability of the goals provided to the user with (1) data acquired during previous studies, and (2) newly gathered data from a single-subject study. As part of the evaluation, we translated IMA counts into ‘steps’, a commonly understandable measure for physical activity, comparing the data acquired from the Activity Coach sensor with a Fitbit, a commercially available pedometer. Although further tests with more subjects and different activities should be performed, we suggest that the default values set to the system are in agreement with the Goal-Setting Theory providing challenging and attainable goals.
The results from this research will be used in future experiments using the Activity Coach and can be adapted to other ambulatory feedback systems regarding promotion of physical activity
Paper folding for an active learning of mathematics: an experience with preservice teachers
Students are active individuals that build, modify and integrate ideas, interacting with the physical world, materials and other students. Furthermore, not all students learn in the same way, some learn better by seeing, others by listening, others by moving. So, we developed an exploratory study of qualitative nature, with elementary preservice teachers, where the emphasis was on a teaching approach based on problem solving, mathematical communication and collaborative work that involved the manipulation of a sheet of paper. We intended to identify the relevance of this approach with preservice teachers and what were the main difficulties revealed, related to the proposed tasks. Preliminary results allowed to identify several difficulties in terms of mathematical communication and the manipulation of the sheet of paper to solve a problem. However, they reacted positively to the tasks, expressing interest, motivation and recognition of its importance in mathematical learning at any level.Les étudiants sont des individus actifs, qui construisent, modifient et intègrent des idées, en interaction avec le monde physique, des matériaux et d’autres étudiants. En outre, tous n'apprennent pas de la même manière: certains apprennent mieux en regardant, d'autres en écoutant, d'autres en bougeant. Nous avons donc développé une étude exploratoire de nature qualitative, avec des futures instituteurs, promouvant une approche pédagogique basée sur la résolution de problèmes, la communication mathématique et le travail collaboratif impliquant la manipulation d’une feuille de papier. Nous voulions déterminer la pertinence de cette approche pour les futures enseignants et identifier les les principales difficultés révélées face aux tâches proposées. Les résultats préliminaires ont permis d'identifier plusieurs difficultés relevant de la communication mathématique et de la manipulation de la feuille de papier pour résoudre un problème. Cependant, les participants ont réagi positivement aux tâches, exprimant leur intérêt et motivation et reconnaissant leur importance pour l’apprentissage des mathématiques à tous les niveaux.publishe
Mathematics outside the classroom: examples with pre-service teachers
The classroom is only one of the "homes" where education takes place. The use
of non-formal teaching contexts, such as the surrounding environment, constitutes an
educational context that can promote positive attitudes among students and an additional
motivation for the study of mathematics. Teaching should be enriched with challenging
tasks, aimed at developing cognitive abilities, such as problem posing and solving, and also
encourage creative thinking. Thus, arise the trails, which consist of a sequence of tasks that
the students have to solve, along a preplanned route. In this process, teacher education has a
fundamental role, providing (future) teachers with the same experiences they are expected to
offer their own students. The trails have great potential for all the students who experience
them. Thus, we will discuss some of that potential developed in the context of pre-service
teacher training.0D1E-4824-1244 | Ana Cristina Coelho Barbosainfo:eu-repo/semantics/publishedVersio
