RESUMO

BACKGROUND: Children with motor delays are at increased risk for delayed means-end problem-solving (MEPS) performance. OBJECTIVES: To evaluate children with motor delays: 1) the impact of motor delay severity and MEPS mastery timing on developmental trajectories of MEPS; and 2) the effectiveness of Sitting Together And Reaching To Play (START-Play) intervention for improving MEPS. METHODS: This represents a secondary analysis from a multi-site randomized controlled trial, with blinded assessors and prospective registration. Children with mild or significant motor delays (n = 112, mean age=10.80, SD=2.59 months at baseline) were randomly assigned to START-Play or usual care early intervention (UC-EI) and assessed at five visits across one year using the Means-End Problem-Solving Assessment Tool that included three 30-second MEPS trials per visit. Task mastery occurred at the first visit the child achieved the highest level of performance in at least two of the three trials. Multilevel analyses evaluated trajectories of MEPS outcomes dependent upon the timing of MEPS mastery, motor delay severity, and intervention group. RESULTS: At baseline, children with mild motor delays demonstrated better MEPS than children with significant delays, but this difference was only observed for children who achieved mastery late. Children with significant delays demonstrated greater improvements in MEPS in the post-intervention phase compared to children with mild delays. No MEPS differences were found between START-Play and UC-EI. CONCLUSION: Motor delay severity and timing of task mastery impacted MEPS trajectories, whereas START-Play intervention did not impact MEPS for children with motor delays.

RESUMO

Insights, characterized by sudden discoveries following unsuccessful problem-solving attempts, are fascinating phenomena. Dynamic systems perspectives argue that insight arises from self-organizing perceptual and motor processes. Entropy and fractal scaling are potential markers for emerging new and effective solutions. This study investigated whether specific features associated with self-organization in dynamical systems can distinguish between individuals who succeed and those who fail in solving insight tasks. To achieve this, we analyzed pupillary diameter fluctuations of children aged 6 to 12 during the 8-coin task, a well-established insight task. The participants were divided into two groups: successful (n = 24) and unsuccessful (n = 43) task completion. Entropy, determinism, recurrence ratio, and the ß scaling exponent were estimated using Recurrence Quantification and Power Spectrum Density analyses. The results indicated that the solver group exhibited more significant uncertainty and lower predictability in pupillary diameter fluctuations before finding the solution. Recurrence Quantification Analysis revealed changes that went unnoticed by mean and standard deviation measures. However, the ß scaling exponent did not differentiate between the two groups. These findings suggest that entropy and determinism in pupillary diameter fluctuations can identify early differences in problem-solving success. Further research is needed to determine the exclusive role of perceptual and motor activity in generating insights and investigate these results' generalizability to other tasks and populations.

RESUMO

Resumo A resolutividade é um dos princípios do Sistema Único de Saúde (SUS) no Brasil, com sua capacidade de resolver os problemas da população nos diferentes níveis de complexidade da saúde. O Subsistema de Atenção à Saúde Indígena (SASI-SUS) integra este sistema, respeitando as especificidades das populações indígenas. O objetivo deste artigo é analisar a percepção dos profissionais e gestores de uma Casa de Saúde Indígena (CASAI) a respeito da resolutividade no subsistema quanto às circunstâncias da pandemia. Pesquisa qualitativa, de caráter descritivo, à luz da Política Nacional de Atenção à Saúde dos Povos Indígenas (PNASPI) e da teoria hermenêutica de Paul Ricoeur. Foram realizadas entrevistas entre os participantes a fim de registrar as experiências no processo de trabalho dos atores que cuidam dos indígenas referenciados à Manaus, Amazonas. Foram identificadas, pelas entrevistas, quatro temáticas essenciais: cuidado cultural; educação permanente em saúde & educação em saúde; negociação & improviso e; acolhimento & infraestrutura. A CASAI é uma instituição que vai além de um centro de apoio ou alojamento, sendo ponto de articulação entre os diferentes níveis de atenção aos indígenas e local de produção de cuidados e de saberes, tal como da construção de suas relações, resultando em um espaço resolutivo.

Abstract Problem-solving is one of the principles of the Unified Health System (SUS) in Brazil, with its ability to solve the health problems of the population at different levels of complexity. The Indigenous Health Care Subsystem (SASI-SUS) is part of this service, respecting the specificities of indigenous populations. The scope of this article is to analyze the perception of professionals and managers of an Indigenous Health Center (CASAI) regarding its ability to cope with the circumstances of the pandemic. It involved qualitative and descriptive research under the National Health Care Policy for Indigenous Peoples (PNASPI) and Paul Ricoeur's hermeneutic theory. Interviews were conducted with participants in order to record the experiences in the work process of the actors who assist the indigenous people housed at CASAI. Four essential themes were identified in the interviews: cultural care; permanent education in health & health education; negotiation & improvisation; and reception & infrastructure. CASAI is an institution that is more than a support center or accommodation, being a crossover point between the different levels of care and knowledge production of the indigenous people, as well as a place for establishing a relationship, resulting in a problem-solving space.

RESUMO

RESUMO: A resolutividade relaciona-se à capacidade de solução dos problemas de saúde nos serviços. Em 1999, o Subsistema de Atenção à Saúde Indígena foi integrado ao Sistema Único de Saúde no Brasil, passando a seguir os seus princípios e diretrizes. Este estudo teve por objetivo identificar e mapear os desafios ou problemas relacionados às práticas em saúde para a resolutividade no Subsistema de Saúde Indígena após a integração. Trata-se de uma revisão de escopo que utilizou seis bases de dados nacionais e internacionais. Os estudos elegíveis tiveram como critério base o mnemônico PCC (P: população indígena; C: desafios ou problemas para a resolutividade; C: subsistema de saúde indígena brasileiro). Foram encontrados 1.748 estudos e selecionados 33, com predomínio de estudos qualitativos. Os desafios ou problemas sensíveis para o processo da resolutividade foram encontrados nos aspectos que tangem à educação em saúde, à interculturalidade, ao acesso universal e aos recursos em gestão. O saber tradicional é pouco valorizado pelo sistema de saúde. A deficiência de recursos humanos e materiais, a falta de efetiva educação permanente e de capacitações para trabalhar no contexto intercultural produzem barreiras de acesso e comprometem a resolutividade nos serviços, aumentando assim as iniquidades em saúde.

ABSTRACT: Resolubility relates to the ability to solve health problems in services. In 1999, the Indigenous Health Care Subsystem was integrated into the Brazilian Unified Health System, following its principles and guidelines. The objective of this study was to identify and map the challenges or problems related to health practices for solving in the Indigenous Health Subsystem after integration. This is a scope review that used six national and international databases. Eligible studies were based on mnemonic PCC (P: indigenous population; C: challenges or problems for resolution; C: Brazilian indigenous health subsystem). A total of 1,748 studies were found and 33 were selected, with predominance of qualitative studies. The challenges or problems that are sensitive to the resolution process were found in the aspects that are related to health education, interculturality, universal access and management resources. Traditional knowledge is underrated by the health system. The deficiency of human and material resources, the lack of effective permanent education and capacitations to work in the intercultural context, produce barriers to access and compromise the resolubility in services, thus increasing the inequities in health.

RESUMEN: La resolución se refiere a la capacidad de resolver problemas de salud en los servicios. En 1999, el Subsistema de Atención de Salud Indígena se integró en el Sistema Único de Salud de Brasil, siguiendo sus principios y directrices. El objetivo de este estudio fue identificar y mapear los desafíos o problemas relacionados con las prácticas de salud para resolver en el Subsistema de Salud Indígena después de la integración. Esta es una revisión de alcance que utilizó seis bases de datos nacionales e internacionales. Los estudios elegibles se basaron en PCC mnemónicos (P: población indígena; C: desafíos o problemas para la resolución; C: subsistema de salud indígena brasileño). Se encontraron 1.748 estudios y se seleccionaron 33, con predominio de estudios cualitativos. Los desafíos o problemas que son sensibles al proceso de resolución se encontraron en los aspectos que están relacionados con la educación en salud, la interculturalidad, el acceso universal y los recursos de gestión. El conocimiento tradicional es subestimado por el sistema de salud. La deficiencia de recursos humanos y materiales, la falta de educación permanente efectiva y de capacitaciones para trabajar en el contexto intercultural, producen barreras para acceder y comprometer la solubilidad en los servicios, aumentando así las desigualdades en salud.

RESUMO

Resumo Fundamento O raciocínio clínico está no centro da prática médica e emaranhado em uma confusão conceitual.A teoria da dualidade da probabilidade permite analisar seus aspectos objetivos e subjetivos. Objetivos Fazer revisão sistemática da literatura sobre o raciocínio clínico para tomada de decisão na educação médica e uma proposta chamada "Pensamento Conforme a Regra de Bayes" (PCRB). Métodos A revisão sistemática foi realizada na base PubMed até a data de 27/02/2022, seguindo metodologia rigorosa, por pesquisador experiente em revisão sistemática. A proposta PCRB, apresentada na discussão, foi elaborada no trabalho de conclusão de graduação em Filosofia na Universidade Federal de Minas Gerais. Usou-se a insuficiência cardíaca como exemplo. Resultados De 3340 artigos encontrados, incluíram-se 154 artigos: 24 tratando da condição de incerteza; 87 tratando de conceitos vagos (discussão de casos, heurística, lista de vieses cognitivos, escolha com sabedoria) incluídos sob o termo 'arte'; e 43 discutindo a ideia geral de raciocínio indutivo ou dedutivo. PCRB oferece regras de coerência e reprodutibilidade, inferência sob incerteza e regra de aprendizado, e pode, por meio da perspectiva subjetiva sobre a probabilidade, incorporar aqueles termos vagos classificados como 'arte', bem como argumentos e evidências. Conclusões A revisão sistemática mostra que o raciocínio é fundado na incerteza, predominantemente probabilístico; além de mostrar algumas possibilidades de erro do pensamento hipotético-dedutivo. O PCRB é um pensamento probabilístico em duas etapas que pode ser ensinado. A regra de Bayes é uma ferramenta linguística, uma regra geral de raciocínio, de diagnóstico, de comunicação científica e de revisão do conhecimento médico conforme novas evidências.

Abstract Background Clinical reasoning is at the core of medical practice and entangled in a conceptual confusion. The duality theory in probability allows to evaluate its objective and subjective aspects. Objectives To conduct a systematic review of the literature about clinical reasoning in decision making in medical education and to propose a "reasoning based on the Bayesian rule" (RBBR). Methods A systematic review on PubMed was conducted (until February 27, 2022), following a strict methodology, by a researcher experienced in systematic review. The RBBR, presented in the discussion section, was constructed in his undergraduate dissertation in Philosophy at Minas Gerais Federal University. Heart failure was used as example. Results Of 3,340 articles retrieved, 154 were included: 24 discussing the uncertainty condition, 87 on vague concepts (case discussion, heuristics, list of cognitive biases, choosing wisely) subsumed under the term "art", and 43 discussing the general idea of inductive or deductive reasoning. RBBR provides coherence and reproducibility rules, inference under uncertainty, and learning rule, and can incorporate those vague terms classified as "art", arguments and evidence, from a subjective perspective about probability. Conclusions This systematic review shows that reasoning is grounded in uncertainty, predominantly probabilistic, and reviews possible errors of the hypothetico-deductive reasoning. RBBR is a two-step probabilistic reasoning that can be taught. The Bayes theorem is a linguistic tool, a general rule of reasoning, diagnosis, scientific communication and review of medical knowledge according to new evidence.

RESUMO

Self-monitoring regulates the expression of behavior, which can facilitate relationships in different contexts. The aim of this study was to confirm the factorial structure of the exploratory analysis of the Self-monitoring Scale (SMS) and investigate the effect of the independent variable Self-monitoring on the dependent variable Social Problem Solving. Participants were 400 university students of different degrees, both sexes, aged between 18 and 58 years (M=31.3 and SD=9.4) and with data collected on the spot. Confirmatory Factor Analysis found fit indexes that support the two-factor model, corroborated by the literature. The regression analysis demonstrated that Self-monitoring predicted the Resolution of Social Problems regarding the Problem Orientation (PO) factor, suggesting that students with a higher PO would be less aware of the context to regulate behavior. The study showed the functioning of the instruments that measure concepts that are still little explored in Higher Education studies. (AU)

A automonitoria autorregula a expressão do comportamento, o que pode facilitar os relacionamentos em diferentes contextos. O objetivo do estudo foi confirmar a estrutura fatorial da análise exploratória da Escala de Automonitoria (EA) e investigar o efeito da variável independente Automonitoria na variável dependente Resolução de Problemas Sociais. Participaram 400 universitários, ambos os sexos, idade entre 18 e 58 anos (M = 31,3 e DP = 9,4) e os dados foram coletados in loco. A análise fatorial confirmatória encontrou índices de ajuste que sustentam o modelo de dois fatores, corroborado pela literatura. A análise de regressão apontou que a Automonitoria predisse a Resolução de Problemas Sociais quanto ao fator Orientação de Problema (OP), sugerindo que alunos com maior OP estariam menos atentos ao contexto para regular o comportamento. O estudo mostrou o funcionamento dos instrumentos que mensuram conceitos ainda pouco explorados nas pesquisas na Educação Superior. (AU)

RESUMO

The nature of the area of mathematical competitions as a design science is considered, historical roots of mathematical problem-solving competitions are traced, the complementary aspects of mathematics as theory building and as problem solving are touched upon in relation to the practice of competitions. Two historical figures, Euler and Erdos, emerge, and the appropriateness of many of Euler's mathematical ventures are seen as role models for competition mathematics as first put into practice in mathematical competitions towards the end of the nineteenth century. Distinctions and definitions are made, a venture into identifying competition syllabi and the principal types of reasoning employed in solving competition problems is explored, and a description of the many different types of competitions is considered. Interaction between the field of mathematics itself and problem-solving competitions is briefly explored, as are the possibilities that open when competitions and their access to huge amounts of data, both national and international, are taken into account in research belonging to mathematics education. Finally, the range of topics addressed in this special issue of ZDM is covered, along with some possible conclusions relating to the components of the overview.

RESUMO

Esta investigación se propuso explorar y analizar las características que presenta la interacción entre niños y adultos con un juego digital e interactivo que implica la solución de un problema, el armado de rompecabezas en una tablet. Se realizaron observaciones seminaturalísticas en los hogares y se indagó mediante un cuestionario la tenencia y hábitos de uso de tecnologías. Las interacciones se analizaron con un sistema de categorías construido inductivamente. Adultos y niños participaron de manera activa en la tarea. Los adultos ayudaron a los niños en su mayo-ría por medio de preguntas, guías e informaciones, acompañadas con frecuencia de acciones no verba-les como señalamientos y arrastre de las piezas. Las intervenciones infantiles fueron en su mayoría no verbales. A pesar de encontrar una fuerte presencia de tecnologías en los hogares, se diferenciaron dos grupos respecto a hábitos de uso: un grupo reportó un bajo uso y los niños no accedían a tablets, otro expresó mayor uso y los niños las utilizabancon frecuencia. Las intervenciones en el armado del rompecabezas se diferenciaron en función de la experiencia infantil con tecnologías. Los resultados se discuten a la luz de investigaciones previas sobre la interacción adulto-niño con herramientas analógicas y digitales.

This study aimed to explore and analyze the charac-teristics of the interaction between children and adults with a digital and interactive game that involves solv-ing a problem, that is, assembling puzzles on a tablet. Semi-naturalistic observations of the interactions in the homes were carried out, and the possession and the habits of the use of were investigated through a survey. The interactions were analyzed with an induc-tively constructed category system. Adults and chil-dren actively participated in the task. Adults helped the children mainly through questions, guidance, and information, accompanied frequently by nonverbal actions, such as pointing at and sliding the pieces. Most of the children's interventions were nonverbal. Despite finding a significant technology presence in the homes, two groups were differentiated regard-ing their habits of use. One group reported little use of technology and no access to tablets for children. Another one expressed that the children used tablets frequently. The interventions in the task differed ac-cording to the children's experience with technologies. The results were discussed considering previous research on adult-child interaction with analogical and digital tools.

RESUMO

Metacognitive ability has been described as an important predictor of several processes involved in learning, including problem-solving. Although this relationship is fairly documented, little is known about the mechanisms that could modulate it. Given its relationship with both constructs, we decided to evaluate the impact of self-knowledge on PS. In addition, we inspected whether emotional (self-reported anxiety) and interpersonal (attitudes towards social interdependence) variables could affect the relationship between metacognition and problem-solving. We tested a sample of 32 undergraduate students and used behavioural tasks and self-report questionnaires. Contrary to the literature, we found no significant relationship between metacognition and problem-solving performance, nor a significant moderating effect when including emotional and interpersonal variables in the model. In contrast, we observed a significant moderating model combining metacognition, self-reported anxiety and attitudes towards social interdependence. It was found that participants with high metacognition reported attitudes unfavourable towards interdependence when they felt high anxiety. These results suggest that already anxious individuals with high metacognition would prefer to work alone rather than with others, as a coping mechanism against further anxiety derived from cooperation. We hypothesise that in anxiogenic contexts, metacognition is used as a tool to compare possible threats with one's own skills and act accordingly, in order to maximise one's own performance. Further studies are needed to understand how metacognition works in contexts adverse to learning.

RESUMO

In this paper we present a theoretical discussion on how problems issued from discrete mathematics can develop the attitudes, skills, and knowledge required for scientific mathematical activity in the classroom. We do so via the research situation for the classroom model by performing mathematical and didactical analyses of a problem issued from discrete geometry, and we present the results of a preliminary experiment conducted with Chilean students between the ages of 11 and 13. Our chosen problem asked students to tile a fixed square with a finite number of smaller squares. From the theoretical analysis and the preliminary experimentation, we conclude that this problem, and problems issued from discrete mathematics in general, can induce genuine mathematical activity in lower-secondary school students. In particular, we conclude that this problem is effective in developing the knowledge, skills and attitudes advocated in the Chilean mathematics curriculum.
