The role of musical aptitude in the pronunciation of English vowels among Polish learners of English

It has long been held that people who have musical training or talent acquire L2 pronunciation more successfully than those that do not. Indeed, there have been empirical studies to support this hypothesis (Pastuszek-Lipińska 2003, Fonseca-Mora et al. 2011, Zatorre and Baum 2012). However, in many of such studies, musical abilities in subjects were mostly verified through questionnaires rather than tested in a reliable, empirical manner. Therefore, we run three different musical hearing tests, i.e. pitch perception test, musical memory test, and rhythm perception test (Mandell 2009) to measure the actual musical aptitude in our subjects. The main research question is whether a better musical ear correlates with a higher rate of acquisition of English vowels in Polish EFL learners. Our group consists of 40 Polish university students studying English as their major who learn the British pronunciation model during an intense pronunciation course. 10 male and 30 female subjects with mean age of 20.1 were recorded in a recording studio. The procedure comprised spontaneous conversations, reading passages and reading words in isolation. Vowel measurements were conducted in Praat in all three speech styles and several consonantal contexts. The assumption was that participants who performed better in musical tests would produce vowels that are closer to the Southern British English model. We plotted them onto vowel charts and calculated the Euclidean distances. Preliminary results show that there is potential correlation between specific aspects of musical hearing and different elements of pronunciation. The study is a longitudinal project and will encompass two more years, during which we will repeat the recording procedure twice to measure the participants’ progress in mastering the English pronunciation and comparing it with their musical aptitude.

Processus d’adaptation des personnes vivant avec la schizophrénie et ayant un soutien social limité

Résumé : La schizophrénie est un trouble mental grave qui affecte toutes les facettes de la vie de la personne. En outre, le manque de soutien social est un problème important qui contribue à l’aggravation de la maladie, notamment en influençant négativement la capacité d’adaptation. Chez les personnes atteintes de schizophrénie, la capacité à utiliser des stratégies d’adaptation adéquates et efficaces est essentielle afin d’améliorer la santé, le bien-être et la prévention des rechutes. Cette recherche utilise la conception de l’adaptation de Roy (2009). De nombreuses études confirment la présence de difficultés d’adaptation chez ces personnes. De plus, le processus d’adaptation lui-même reste mal connu. La question de recherche était : Quel est le processus d’adaptation des personnes vivant avec la schizophrénie lorsque leur soutien social est limité ? Cette question sous-tendait deux objectifs : 1) décrire le processus d’adaptation des personnes atteintes de schizophrénie dans un contexte de soutien social limité et 2) contribuer au développement du modèle de Roy dans le contexte des troubles mentaux graves. Le devis de recherche était la théorisation ancrée constructiviste, auprès de 30 personnes vivant avec la schizophrénie. Les données étaient composées d’entrevues et de résultats de trois questionnaires qui ont contribué à décrire de façon plus détaillée le profil des participants. Les résultats sont une modélisation du processus d’adaptation nommée « les filtres dans le processus d’adaptation des personnes vivant avec la schizophrénie ». Cette modélisation met en lumière le fait que le potentiel d’adaptation des personnes vivant avec la schizophrénie est affecté à la fois par des éléments de l’environnement social et des éléments inhérents à la maladie elle-même. Ces éléments altèrent la possibilité et la capacité à utiliser des stratégies d’adaptation adéquates et efficaces. Ces résultats de recherche pourraient permettre d’améliorer l’évaluation des personnes atteintes de schizophrénie et de diminuer les « inconnues » dans l’effet des interventions, tout comme de favoriser les actions visant à lutter contre les conditions sociales qui nuisent à l’adaptation.

A Figured Worlds Perspective on Middle School Learners' Climate Literacy Development

The purpose of this study was to investigate the nature of the relationship between middle school science learners’ conditions and their developing understandings of climate change. I applied the anthropological theoretical perspective of figured worlds (Holland, Lachicotte, Skinner, & Cain, 1998) to examine learners’ views of themselves and their capacities to act in relation to climate change. My overarching research question was: How are middle school science learners’ figured worlds of climate change related to the conditions in which they are embedded? I used a descriptive single-case study design to examine the climate change ideas of eight purposefully selected 6th grade science learners. Data sources included: classroom observations, curriculum documents, interviews, focus groups, and written assessments and artifacts, including learners’ self- generated drawings. I identified six analytic lenses with which to explore the data. Insights from the application of these analytic lenses provided information about the elements of participants’ climate change stories, which I reported through the use of a storytelling heuristic. I then synthesized elements of participants’ collective climate change story, which provided an “entrance” (Kitchell, Hannan, & Kempton, 2000, p. 96) into their figured world of climate change. Aspects of learners’ conditions—such as their worlds of school, technology and media use, and family—appeared to shape their figured world of climate change. Within their figured world of climate change, learners saw themselves—individually and as members of groups—as inhabiting a variety of climate change identities, some of which were in conflict with each other. I posited that learners’ enactment of these identities – or the ways in which they expressed their climate change agency – had the potential to reshape or reinforce their conditions. Thus, learners’ figured worlds of climate change might be considered “spaces of authoring” (Holland et al., 1998, p. 45) with potential for inciting social and environmental change. The nature of such change would hinge on the extent to which these nascent climate change identities become salient for these early adolescent learners through their continued climate change learning experiences. Implications for policy, curriculum and instruction, and science education research related to climate change education are presented.

La jerarquía normativa urbana especial como referencial de política pública de planeación urbana en Colombia

A partir de la pregunta de investigación ¿Cuál es la política pública de planeación urbana de la ciudad de Medellín? el artículo presenta la denominada jerarquía normativa urbana especial como parte del referencial que ha dado y sigue dando lugar a la citada política pública. Para ello, inicialmente se reseña la figura de política pública dentro de la cual se definen las categorías de referencial de política y flujo decisional, propuestas en el modelo de análisis de Pierre Muller, desde las cuales se legitima la naturaleza pública de una política y se diferencia de la política de Estado o de gobierno. Seguidamente se abordan los componentes que conforman la jerarquía normativa urbana especial, comenzando por los desarrollados por la Corte Constitucional en su jurisprudencia; posteriormente los propuestos por la doctrina, frente a la cual se plantea la modificación de su esquema a partir de la derogación del artículo 7 de la Ley 388 de 1997, la actual composición de la función administrativa urbana desde la dispersión de competencias territoriales conferidas por ley, y el anacrónico rol de las áreas metropolitanas en materia urbana.

The Effect of using online homework exercises on student achievement in a Quantitative methods course

Abstract: Quantitative Methods (QM) is a compulsory course in the Social Science program in CEGEP. Many QM instructors assign a number of homework exercises to give students the opportunity to practice the statistical methods, which enhances their learning. However, traditional written exercises have two significant disadvantages. The first is that the feedback process is often very slow. The second disadvantage is that written exercises can generate a large amount of correcting for the instructor. WeBWorK is an open-source system that allows instructors to write exercises which students answer online. Although originally designed to write exercises for math and science students, WeBWorK programming allows for the creation of a variety of questions which can be used in the Quantitative Methods course. Because many statistical exercises generate objective and quantitative answers, the system is able to instantly assess students’ responses and tell them whether they are right or wrong. This immediate feedback has been shown to be theoretically conducive to positive learning outcomes. In addition, the system can be set up to allow students to re-try the problem if they got it wrong. This has benefits both in terms of student motivation and reinforcing learning. Through the use of a quasi-experiment, this research project measured and analysed the effects of using WeBWorK exercises in the Quantitative Methods course at Vanier College. Three specific research questions were addressed. First, we looked at whether students who did the WeBWorK exercises got better grades than students who did written exercises. Second, we looked at whether students who completed more of the WeBWorK exercises got better grades than students who completed fewer of the WeBWorK exercises. Finally, we used a self-report survey to find out what students’ perceptions and opinions were of the WeBWorK and the written exercises. For the first research question, a crossover design was used in order to compare whether the group that did WeBWorK problems during one unit would score significantly higher on that unit test than the other group that did the written problems. We found no significant difference in grades between students who did the WeBWorK exercises and students who did the written exercises. The second research question looked at whether students who completed more of the WeBWorK exercises would get significantly higher grades than students who completed fewer of the WeBWorK exercises. The straight-line relationship between number of WeBWorK exercises completed and grades was positive in both groups. However, the correlation coefficients for these two variables showed no real pattern. Our third research question was investigated by using a survey to elicit students’ perceptions and opinions regarding the WeBWorK and written exercises. Students reported no difference in the amount of effort put into completing each type of exercise. Students were also asked to rate each type of exercise along six dimensions and a composite score was calculated. Overall, students gave a significantly higher score to the written exercises, and reported that they found the written exercises were better for understanding the basic statistical concepts and for learning the basic statistical methods. However, when presented with the choice of having only written or only WeBWorK exercises, slightly more students preferred or strongly preferred having only WeBWorK exercises. The results of this research suggest that the advantages of using WeBWorK to teach Quantitative Methods are variable. The WeBWorK system offers immediate feedback, which often seems to motivate students to try again if they do not have the correct answer. However, this does not necessarily translate into better performance on the written tests and on the final exam. What has been learned is that the WeBWorK system can be used by interested instructors to enhance student learning in the Quantitative Methods course. Further research may examine more specifically how this system can be used more effectively.

Première phase d’un programme de recherche sur l’utilisation de vasopresseurs en traumatologie : étude observationnelle et revue systématique

Résumé : Les réanimateurs ont recours à des interventions à la fois médicales et chirurgicales en contexte de choc traumatique. Le rôle des vasopresseurs dans cette prise en charge est controversé. Alors que les lignes directrices américaines considèrent que les vasopresseurs sont contre-indiqués, certains experts européens en encouragent l’utilisation pour diminuer le recours aux liquides intraveineux. Avant d’élaborer un essai clinique, il importe de comprendre la pratique actuelle à laquelle se comparera une intervention expérimentale, ainsi que de connaître le niveau d’incertitude dans la littérature entourant la question de recherche. Le Chapitre 2 de ce travail présente une étude observationnelle effectuée dans un centre régional de traumatologie québécois. Cette étude documente les pratiques de réanimation adoptées par les équipes de traumatologie en 2013, particulièrement le recours aux liquides intraveineux et aux vasopresseurs. Les résultats démontrent que les vasopresseurs ont été utilisés chez plus de 40% des patients, particulièrement les victimes de traumatismes crâniens (RC 10.2, IC 95% 2.7-38.5). De plus, les vasopresseurs ont été administrés dans les phases précoces de la réanimation, soit avant l’administration d’un volume important de liquides. Le Chapitre 3 présente une revue systématique portant sur l’utilisation précoce de vasopresseurs en traumatologie. Les bases de données MEDLINE, EMBASE, CENTRAL et ClinicalTrials.gov ont été interrogées, ainsi que les abrégés présentés dans les conférences majeures en traumatologie depuis 2005. La sélection des études et l’extraction des données ont été effectuées en duplicata. Aucune donnée interprétable n’a pu être extraite des études observationnelles et le seul essai clinique identifié n’avait pas une puissance suffisante (RR de mortalité avec vasopresseurs 1.24, IC 95 % 0.64-2.43). Cette synthèse met en lumière l’incertitude scientifique sur le rôle des vasopresseurs en traumatologie. Les vasopresseurs ont des bénéfices potentiels importants, puisqu’ils permettent entre autres de supporter étroitement l’hémodynamie des patients. En revanche, ils présentent aussi un fort potentiel de dangerosité. Ils sont utilisés fréquemment, malgré l’absence de données sur leurs risques et bénéfices. Ces trouvailles établissent clairement la pertinence clinique et le bien-fondé éthique d’un essai clinique sur le rôle des vasopresseurs dans la prise en charge précoce des victimes de traumatismes.

Gestão Social em Empreendimentos Econômicos Solidários: uma abordagem no Oeste Potiguar

The central research question was to search for data to ratify the theory and discourse of the so-called practitioners of economic solidarity, by defending the substantive rationality should guide the principles of economic solidary, designing the space economy incidental and not the primacy of relations in determining social as well, reflecting the predominance of dimensions of social management in administrative practices of ESS's. For both analyzed the theoretical dimensions of social management - sociopolitical, economic, organizational and environmental - manifested in organizational practices supportive of economic organization Potiguar West. For the success of the research realized the triangulation involving a combination of quantitative and qualitative methodological approaches. At first the research will use a quantitative approach, from the cluster analysis, to verify the behavior of the sample chosen for this study. In the second stage of the qualitative study was carried out focus group technique (FLICK, 2002) for further analysis of the dimensions of social management on organizational practices supportive of economic organization, related to the principles of Solidary Economy, established in a quantitative approach. In quantitative analysis, the socio-political dimension, it was clear that the more equity instruments of internal and external, from the purposeful living in public spaces, the best monetary results. Another point worth stressing concerns the economic dimension, with the practice reciprocity prevailing in market. Thus, the qualitative approach was possible to understand the processes of exchange of product or service. Rural enterprises surveyed in the allocation of the agro-ecological products have the following scale of priority, sequentially: self-consumption (domestic), market and exchange. The research leads to the fact that training and practices that enhance the socio-political dimension (knowledge, empowerment, sense of belonging) become the guiding principle for the strengthening of the social management in the context of other dimensions, leading to gains sociopolitical, economic, organizational and environmental. Despite the weaknesses found in the organizational dimension and environment, both in a quantitative as in qualitative, we determined that the practices of ESS's Potiguar West incorporate predominantly elements of social management and economic solidarity, with a preponderance of substantive rationality in the primacy of the instrumental. Finally, research has brought information that the participants of the ESS's do not give the money economy primacy in determining social relations, which in turn leads to the confirmation that, in practice the solidarity economy, prevailing the dominance of substantive rationality, as a guide for organizational practices

Orientacje zawodowe młodzieży akademickiej będącej w okresie tranzycji z edukacji na rynek pracy

The modern world, which is characterized by diversity, uncertainty and ambiguity, affects the functioning of the younger generation. Young people experience a variety of problems associated with entering into adulthood. Being on the stage “between” youth and adulthood requires countless choices. The functioning of youth is still an interesting cognitive topic, worthy of scientific knowledge, therefore, the article seeks to answer the question: What is the professional orientation of contemporary university students? The article thesis consists of two parts. The first part has a theoretical character. It deals with issues of professional orientation. The second part of the article is an empirical analysis and attempt to answer the research question: What are the professional orientations of students?

Tutors as mediators of exchange student experiences: evaluation of the international student tutor system at the University of Turku

As academic student mobility is increasing, improving the functionality of international operations is recognised as a competitive advantage at tertiary education institutions. Although many scholars have researched the experiences of exchange students, the role of student tutors and their contribution to exchange students’ experiences is still an unknown factor. This research examines international tutoring at the University of Turku, and aims to understand better the way tutoring contributes to exchange experiences and to explore the functionality of the tutor system and discover areas for improvements. To achieve these goals, the research seeks to answer the fundamental research question: What is the role of tutors in mediating exchange experiences? The theoretical framework combines literature on mediating exchange experiences, the phenomenon of studying abroad, the process of adaptation, the importance of cross-cultural communication, and the role of student tutors as mediators. Based on the literature review, a theoretical model for studying the mediation of exchange experiences is introduced. The model’s applicability and validity is examined through a case study. Three methods were used in the empirical research: surveys, participant observations, and interviews. These methods provided extensive data from three major parties of the tutor system: tutors, exchange students, and the international office. The findings of the research reveal that tutoring – instrumental leading and social and cultural mediating – generates both negative and positive experiences depending on the individuals’ expectations, motivations, relationships, and the nature of the tutoring. Although functional, there are a few weaknesses in the tutor system. Tutors tend to act as effective instrumental leaders, but often fail to create a friendship and contribute to the exchange students’ experience through social and cultural mediation, which is significantly more important in the exchange students’ overall experience in terms of building networks, adapting, gaining emotional experiences, and achieving the stage of personal development and mental change. Based on the weaknesses, three improvements are suggested: (1) increasing comprehensive sharing of information, effective communication, and collective cooperation, (2) emphasising the importance of social and cultural mediation and increasing the frequency of interaction between tutors and exchange students, and (3) improving the recruitment and training, revising the process of reporting and rewarding, and finally, enhancing services and coordination.

Collecting valuable consumer data: Motivating consumers to disclose personal information

Collecting and analyzing consumer data is essential in today’s data-driven business environment. However, consumers are becoming more aware of the value of the information they can provide to companies, thereby being more reluctant to share it for free. Therefore, companies need to find ways to motivate consumers to disclose personal information. The main research question of the study was formed as “How can companies motivate consumers to disclose personal information?” and it was further divided into two subquestions: 1) What types of benefits motivate consumers to disclose personal information? 2) How does the disclosure context affect the consumers’ information disclosure behavior? The conceptual framework consisted of a classification of extrinsic and intrinsic benefits, and moderating factors, which were recognized on the basis of prior research in the field. The study was conducted by using qualitative research methods. The primary data was collected by interviewing ten representatives from eight companies. The data was analyzed and reported according to predetermined themes. The findings of the study confirm that consumers can be motivated to disclose personal information by offering different types of extrinsic (monetary saving, time saving, self-enhancement, and social adjustment) and intrinsic (novelty, pleasure, and altruism) benefits. However, not all the benefits are equally useful ways to convince the customer to disclose information. Moreover, different factors in the disclosure context can either alleviate or increase the effectiveness of the benefits and the consumers’ motivation to disclose personal information. Such factors include the consumer’s privacy concerns, perceived trust towards the company, the relevancy of the requested information, personalization, website elements (especially security, usability, and aesthetics of a website), and the consumer’s shopping motivation. This study has several contributions. It is essential that companies recognize the most attractive benefits regarding their business and their customers, and that they understand how the disclosure context affects the consumer’s information disclosure behavior. The likelihood of information disclosure can be increased, for example, by offering benefits that meet the consumers’ needs and preferences, improving the relevancy of the asked information, stating the reasons for data collection, creating and maintaining a trustworthy image of the company, and enhancing the quality of the company’s website.

Virtuellt lärande på distans : en intervjustudie med finländska gymnasiestuderande.

The aim of this study was to gain a deeper understanding of the learning experiences of upper secondary school students in a virtual learning environment. The focus of the study is younger students aged 16–18. Virtual learning environments are defined as collaborative, interactive and communicative digital environments. The main research question was to distinguish the meaning of learning given by the participants. Did the participants perceive learning potential in the virtual learning environment, and if so, what signifies learning potential? Sub-questions were: What enhances learning? What might inhibit learning in a distance course? How do the participants relate to their role as distant learners? Four upper secondary schools in Finland took part in the study. Thirteen upper secondary students were interviewed after a distance course in social studies. During the analysis, four main categories were identified: responsibility, freedom, time and communication. A constructivist approach to learning was adopted while analysing the interviews, and the categories were understood through cognitive, affective and social dimensions of learning. The implications of the study are that a student-centred pedagogy and a social constructivist course design have the potential to motivate students to interact to learn, while the software, such as Second Life, Google+ and Wikibooks, offers them the possibility to do so. The study introduces an empirically supported concept, virtual learning. Virtual learning assumes an active learner who manages different learning spaces while communicating with people and metacognitively assessing the learning process. At the same time, students get used to the virtual and everchanging nature of information and knowledge.

The Shrine of ʿAbd al-Qādir al-Jīlānī in Baghdad & the Shrine of ʿAbd al-ʿAzīz al-Jīlānī in ʿAqra: Mapping the multiple orientations of two Qādirī Sufi shrines in Iraq

This thesis charts the stakeholder communities, physical environment and daily life of two little studied Qādiriyya Sufi shrines associated with Shaikh ʿAbd al-Qādir al-Jīlānī (1077 – 1165 AD), a 12th century Ḥanbalī Muslim theologian and the posthumous founder of one of the oldest Sufi orders in Islam. The first shrine is based in Baghdad and houses his burial chamber; and the second shrine, on the outskirts of the city of ‘Aqra in the Kurdish region of northern Iraq, is that of his son Shaikh ʿAbd al-ʿAzīz (died 1206 AD). The latter was also known for lecturing in Ḥanbalī theology in the region, and venerated for this as well as his association with Shaikh ʿAbd al-Qādir. Driven by the research question “What shapes the identity orientations of these two Qādiriyya Sufi shrines in modern times?” the findings presented here are the result of field research carried out between November 2009 and February 2014. This field research revealed a complex context in which the two shrines existed and interacted, influenced by both Sufi and non-Sufi stakeholders who identified with and accessed these shrines to satisfy a variety of spiritual and practical needs, which in turn influenced the way each considered and viewed the two shrines from a number of orientations. These overlapping orientations include the Qādirī Sufi entity and the resting place of its patron saint; the orthodox Sunnī mosque with its muftī-imams, who are employed by the Iraqi government; the local Shīʿa community’s neighbourhood saint’s shrine and its destination for spiritual and practical aid; and the local provider of welfare to the poor of the city (soup kitchen, funeral parlour and electricity-generation amongst other services). The research findings also revealed a continuously changing and adapting Qādirī Sufi scene not immune from the national and regional socio-religio-political environments in which the two shrines exist: a non-Sufi national political class vying to influence and manipulate these shrines for their own purposes; and powerful national sectarian factions jostling to do the same. The mixture of stakeholders using and associating with the two shrines were found to be influential shapers of these entities, both physically and spiritually. Through encountering and interacting with each other, most stakeholders contributed to maintaining and rejuvenating the two shrines, but some also sought to adapt and change them driven by their particular orientation’s perspective.

A NARRATIVE CASE STUDY EXAMINING THE EXPEREINCES OF MEN TEACHING SPECIAL EDUCATION IN THE ELEMENTARY GRADES

Over the past several decades, the landscape of the workplace has changed in many industrialized nations. In the United States this time period has seen the outright elimination or outsourcing of well-paying “blue collar” jobs. The workforce continues to evolve, change, and become more global, and men and women are making nontraditional occupational decisions, whether by choice or necessity. The traditional views of men and women have begun to shift. However, gender assumptions about masculinity have failed to keep pace with the shift. There are approximately 1.8 million elementary grade level teachers in United States public schools; of these, a mere 9% are male. The paucity of male teachers in the elementary grades has been a concern for many years. According to the Bureau of Labor Statistics, roughly 86% of all special education teachers are female. In 2012, 86.2% of all special education teachers were female, and by the following year, the number had dropped to 80.4%. The evidence indicates that more men are embarking on nontraditional career paths. Despite theses changes there is minimal research looking at the experiences of men working as special education teachers My goal in this study was to obtain a better understanding of the influences on and the process by which men make the decision to pursuing a career teaching special education in the elementary grades. The study utilized social role theory (Eagly, 1987), and Stead’s (2014) social constructionist theory as well as Williams’ (1992) glass escalator proposition The findings of this study confirm some of the factors related to career choice, experiences and barriers faced by men in nontraditional careers detailed in the literature. Three themes emerged for each research question: Experiences, advocacy, and benefits. Three themes emerged around the second research question exploring the experiences of men in a female-concentrated profession: The male body, communication, and perception. Three themes arose around the third research question: administration, My Masculinity, and pay. The findings run counter to Williams’ glass escalator proposition, which posits men working in female-concentrated professions are at an advantage. The findings advance support for Buschmeyer’s theory of (2013) alternative masculinity.

Trabalhar com a matemática em educação de infância

Este estudo tem como principal objetivo compreender e analisar o modo como crianças de creche e jardim-de-infância resolvem problemas matemáticos e o que pode constranger a resolução. Em particular, procurei analisar a atividade matemática que as crianças desenvolvem quando se confrontam com problemas matemáticos e os desafios com que se deparam. Do ponto de vista metodológico, o estudo enquadra-se numa abordagem qualitativa de investigação e num paradigma interpretativo. Além disso, trata-se de uma investigação-ação orientada pela questão “como otimizar a atividade de resolver problemas matemáticos em contextos de educação de infância?”. Neste âmbito, propus a quatro crianças de creche e a 21 de jardim-de-infância um conjunto de tarefas selecionadas para, potencialmente, terem, para si, algum grau de desafio. Os principais métodos de recolha de dados foram a observação participante, a análise documental e um inquérito por questionário realizado às educadoras cooperantes. O estudo ilustra que é possível envolver crianças de creche e de jardim-de-infância numa atividade de resolução de problemas matemáticos e que esta atividade é favorecida se o contexto dos problemas estiver próximo do que fazem no dia-a-dia da sala. Durante o processo de resolução das tarefas propostas, foram mobilizadas e trabalhadas diversas noções matemáticas. Na creche, todas as crianças evidenciaram possuir conhecimentos acerca da noção topológica “dentro de” e “fora de” e algumas foram bem-sucedidas no uso do processo de classificação, tendo em conta um critério. Neste âmbito, recorreram a representações ativas. No jardim-de-infância, todas as crianças conseguiram fazer a contagem sincronizada das letras do seu nome, de indicar a quantidade de letras, o que indicia o conhecimento da noção de cardinal, e de representar esta quantidade recorrendo tanto a numerais como a representações icónicas. Além disso, foram capazes de interpretar uma tabela de modo a construir um gráfico com barras e de elaborar um pictograma, o que revela possuírem conhecimentos ao nível da literacia estatística. Por último, algumas crianças foram bem-sucedidas na descoberta de estratégias de resolução de problemas que lhes permitiram inventariar exaustivamente todas as possibilidades de resolução e contar, organizadamente, estas possibilidades. No decurso desta atividade surgiram tentativas de generalização, embora nem sempre corretas, sobressaindo o recurso a representações ativas nomeadamente à dramatização de situações. Quanto aos desafios com que se depararam destacam-se, no caso da creche, o uso correto do processo de classificação. No caso do jardim-de-infância, as crianças demonstraram dificuldades em distinguir a legenda do pictograma dos dados, em resolver um problema em que estava em jogo o sentido combinatório da multiplicação e em encontrar estratégias de generalização. O estudo indicia, ainda, que é essencial que o educador proponha tarefas diversificadas e desafiantes que, partindo sempre da curiosidade e interesse das crianças, lhes permitam trabalhar com ideias matemáticas importantes e representar adequadamente o conhecimento com que lidam.
