Whole-Mount Histochemical Protocols in Zebrafish for a Hands-On Developmental Biology Practical Course in Ecuador.

Research-based education at the undergraduate level is ideal for fostering the training of future scientists. In an undergraduate Developmental Biology course, this learning strategy requires the availability of model species and enough research reagents, not only for technique training but also for the development of student original projects. This might be challenging in most countries, where resources are limited. Hence, there is a need to develop low-cost solutions for use in the classroom. In this study, we describe the optimization and use of two low-cost protocols in zebrafish embryos for hands-on practical sessions and project-based learning in a Developmental Biology undergraduate course in Ecuador. These protocols were designed for the practical and experimental learning of vertebrate meroblastic cleavage, gastrulation, and neural crest differentiation. The proposed protocols have been previously described in the literature and use silver nitrate and alcian blue, two relatively inexpensive reagents, to label cell membranes and cartilage. The silver nitrate protocol allows the study of cell contact formation during cleavage and the identification of cellular changes during gastrulation, including yolk internalization and epiboly. The alcian blue staining allows the analysis of cranial mesenchymal differentiation into cartilage. These protocols are ideal for practical sessions due to their ease of application, quick results, adaptability to the class schedule, and robustness in the hands of beginning researchers. Finally, these protocols are adaptable for research-based class projects.

Improving engineering students' understanding of classical physics through visuo-haptic simulations.

Introduction: The teaching process plays a crucial role in the training of professionals. Traditional classroom-based teaching methods, while foundational, often struggle to effectively motivate students. The integration of interactive learning experiences, such as visuo-haptic simulators, presents an opportunity to enhance both student engagement and comprehension. Methods: In this study, three simulators were developed to explore the impact of visuo-haptic simulations on engineering students' engagement and their perceptions of learning basic physics concepts. The study used an adapted end-user computing satisfaction questionnaire to assess students' experiences and perceptions of the simulators' usability and its utility in learning. Results: Feedback from participants suggests a positive reception towards the use of visuo-haptic simulators, highlighting their usefulness in improving the understanding of complex physics principles. Discussion: Results suggest that incorporating visuo-haptic simulations into educational contexts may offer significant benefits, particularly in STEM courses, where traditional methods may be limited. The positive responses from participants underscore the potential of computer simulations to innovate pedagogical strategies. Future research will focus on assessing the effectiveness of these simulators in enhancing students' learning and understanding of these concepts in higher-education physics courses.

Representaciones de estudiantes sobre el conflicto mapuche en Chile y Argentina / Representations of students regarding the Mapuche conflict in Chile and Argentina / Representações estudantis sobre o conflito mapuche no Chile e na Argentina

(analítico) Las investigaciones de las representaciones sociales de estudiantes acerca de los problemas contemporáneos representan un espacio fundamental de exploración. Este estudio busca analizar las representaciones de estudiantes de educación primaria chilenos y argentinos sobre el conflicto entre los Estados de Chile, Argentina y el pueblo mapuche. La investigación es cualitativa, con un enfoque de teoría fundamentada y los datos recolectados a través de grupos focales en escuelas chilenas y argentinas. El análisis realizado se basa en los procedimientos del paradigma de la codificación, con el motivo de indagar de manera procesual y estructural las representaciones sociales. Los resultados revelan el rol que otorgan los estudiantes a la enseñanza de la historia. Las conclusiones sostienen que la enseñanza de la historia no contribuye a la comprensión de este problema.

(analytical) Research on social representations constructed by students in relation to contemporary problems represents a fundamental space for investigative exploration. This study sought to analyze the representations of Chilean and Argentine primary school students regarding the "conflict" between the Chile, Argentina and the Mapuche people. The research was qualitative and used a grounded theory approach. The data was collected through holding focus groups in Chilean and Argentine schools. The analysis involved the use of coding paradigm procedures in order to investigate social representations in a procedural and structural way. The results reveal the role that students give to the teaching of History. The conclusions identify that the teaching of History does not contribute to the understanding of this problem.

(analítico) Este estudo examina o conhecimento sobre as propriedades formais e a função referencial de desenho, escrita e numerais que mães, filhos e filhas (2 anos e meio e 4 anos) apresentados em tarefa de produção conjunta.

As duplas do grupo de 2 anos e meio conversaram sobre a função referencial dos três sistemas, especialmente do desenho. No grupo de 4 anos aumentaram o interesse pela escrita, a consideração das propriedades formais da escrita e dos numerais e as produções independentes de desenho e escrita. O estudo mostrou a produção gráfica conjunta como uma interação educacional na família que estimula a apropriação precoce de sistemas de representação externa.

Freirean inspirations in solidary internationalism between East Timor and Brazil in science education.

The aim of this work is to reflect on the challenging trajectory of international cooperation between East Timor and Brazil, which focused on the need to rethink teacher education from a critical intercultural perspective, aiming to build emancipatory relations, love, and solidarity. From 2009 until 2016, we coordinated the Qualification of Teachers and Teaching of the Portuguese Language program in East Timor, inspired by the dialogicity of Paulo Freire, an educator well known and beloved by the Timorese people for his indirect contribution to the independence of that country. Freire's dialectic denunciation-annunciation was essential to identify the problems and propose solutions with the Timorese and not only for them. In addition, through our experiences in that country, we identified issues like those of Brazilian education as the effects of coloniality and introjections of inferiority and subordination, as well as the transnationalization of education, among other problems. Thus, the Freirean dialectic denunciation-announcement of this praxis, together with Timorese education, drove us to examine our own Brazilian territory, provoking intersectional reflections related to racism, gender and sexuality issues, and social class prejudice, among other forms of oppression. It deepened ways of acting based on critical interculturality and the concept of decolonial pedagogy, which suggested ways to fight for social justice in science education.

O objetivo deste trabalho é refletir sobre a desafiante trajetória de uma cooperação internacional entre Timor-Leste e Brasil que focou na necessidade de repensar a formação de professores em perspectiva intercultural crítica, visando construir relações emancipatórias, de amor e solidariedade. De 2009 a 2016, coordenamos o programa de Qualificação Docente e Ensino de Língua Portuguesa, em Timor-Leste, inspirados pela dialogicidade de Paulo Freire, um conhecido e amado educador do povo timorense, por sua indireta contribuição na independência daquele país. A dialética freireana denúncia-anúncio foi importante não só para enxergarmos os problemas, mas também para propormos soluções com os timorenses e não somente para eles. Além disso, em nossas experiências naquele país, identificamos problemas semelhantes aos da educação brasileira como efeitos de colonialidade, introjeções de inferioridade e subordinação, transnacionalização da educação, entre outras denúncias. Assim, a dialética freireana denúncia-anúncio dessa práxis, junto à educação timorense nos fez olhar para o nosso próprio território brasileiro, provocando reflexões interseccionais relacionadas ao racismo, às questões de gênero e sexualidade, ao preconceito de classe social, entre outras diferentes formas de opressão, aprofundando modos de agir tendo como base a interculturalidade crítica e o conceito de pedagogia decolonial, a qual anunciou caminhos para a luta por justiça social na educação científica.

Education-Enhanced Conventional Care versus Conventional Care Alone for Temporomandibular Disorders: A Randomized Controlled Trial.

The objective of this study was to determine the effect of enhancing conventional care for people with chronic painful temporomandibular disorders (TMD) with an individualised contemporary pain science education (PSE) intervention. In this randomized controlled trial, a consecutive sample of 148 participants (18-55 years of age) was randomized into 2 groups: PSE-enhanced conventional care or Conventional care alone. Conventional care involved a 6-week, 12-session manual therapy and exercise program. The PSE enhancement involved 2 sessions of modern PSE, undertaken in the first 2 treatment sessions. Primary outcomes were pain intensity, assessed with a numeric pain rating scale, and disability, assessed with the craniofacial pain and disability inventory, post-treatment. Linear mixed model analyses were used to investigate between-group differences over time. There was a statistically and clinically meaningful effect of PSE enhancement on disability (Mean Difference = 6.1, 95% CI: 3.3-8.8), but not on pain intensity, post-treatment. Secondary analyses suggested clinically meaningful benefit of PSE enhancement on pain and disability ratings at 10-week and 18-week follow-ups, raising the possibility that preceding conventional care with a PSE intervention may result in long-term benefits. PERSPECTIVE: The addition of modern Pain Science Education (PSE) intervention improved disability for people with chronic TMD receiving manual therapy and exercise, but not pain. A mean difference in pain and disability favoring the PSE group at the 10- and 18-week follow-ups, respectively, suggests that PSE addition resulted in longer-lasting effects. Trial registration: NCT03926767. Registered on April 29, 2019. https://clinicaltrials.gov/ct2/show/NCT03926767.

Drama as a Powerful Tool to Enrich Socio-scientific Argumentation.

Socio-scientific argumentation (SSA) is increasingly being recognized as a key aspect of scientific literacy. Much of the reason for this is that this skill is crucial for helping students to become active participants in twenty-first-century democratic societies in which the construction of informed and critical views of socio-scientific issues (e.g. climate change, COVID-19 vaccination, genetic testing) plays a fundamental role. The problem is that instructors rarely give students explicit and research-based opportunities to enrich their SSA skills. Therefore, the aim of this study was to provide evidence that drama can be used as a platform to enrich argumentation in genetic testing. The data were derived from the written responses and the audio recordings of seventy-six university students (37 females and 39 males, 16-29 years old) in Colombia during a complete drama-based teaching-learning sequence (TLS) supervised by the same instructor. The outcomes suggest that the sequence can be used to enrich argumentation in genetic testing as it effectively provided participants with explicit opportunities to produce both arguments and counterarguments about the controversy whether the use of genetic tests among people should be encouraged. This study contributes to the literature on SSA in science education by demonstrating that drama is a promising tool to enhance argumentation about science-based social issues.

Teaching Forensic Entomology, Forensic Anthropology, and Haematology & Serology during the COVID-19 pandemic: Practical activities for distance learning.

As the COVID-19 pandemic upended college and university instruction throughout the world, instructors were hard-pressed to find suitable alternatives for practical activities typically carried out outside of classrooms-in laboratories, workshops, clinics, and in the field. In response to this unanticipated challenge, they relied on their ingenuity to achieve pre-pandemic goals under pandemic conditions that necessitated the shift to online teaching. The Forensic Science Undergraduate Program housed in the School of Medicine of the National Autonomous University of Mexico was not exempt from this educational upheaval but, due to its interdisciplinary nature, required creating and/or adopting a wide range of activities capable of training students to perform practical tasks associated with subject areas that span the natural and social sciences, the humanities, and the law. This report aims to describe the approaches undertaken in three subjects (Forensic Entomology, Forensic Anthropology, and Hematology & Serology) by interviewing instructors and examining their teaching materials. Also, through online surveys, students' reactions to these approaches were elicited to learn about their suitability and teaching potential. Instructor's experiences during the pandemic have proven to be a rich source of ingenious solutions, with implications well-beyond the current crisis, such as creating blended or fully online courses aimed at larger numbers of students, forensic and legal professionals, and even other instructors. The wide variety of forensic sciences offers the opportunity to innovate and improve the teaching and learning of science, particularly to the benefit of students that must combine their school tasks with professional and/or family duties.

Evaluation of student engagement through knowledge elaboration and the use of comics in Microbiology education.

Despite the many challenges faced by the sudden adaptation of the teaching-learning processes during the emergency remote teaching (ERT) imposed by the COVID-19 pandemic, this period allowed the exploration of innovative educational methods. Here, we report the description and evaluation of a didactic activity designed to foster an active learning environment among Veterinary Medicine undergraduate students enrolling in Microbiology classes during the ERT period at the University of Minas Gerais. The activity consisted of initial expositive classes, followed by students' active search for information, and the execution of a report and short comics covering the topic. The activity was evaluated by a voluntary postquestionnaire. The results suggest that the students had good emotional and educational perception toward the task, and that they noticed the elaboration of the comics as the most valuable tool aiding in the retention of microbiological concepts. We conclude that the proposed strategy, specially by the incorporation of the comics, helped the meaningful learning of microbiology.

Neuroscience Knowledge and Endorsement of Neuromyths among Educators: What Is the Scenario in Brazil?

The field of neuroscience has seen significant growth and interest in recent decades. While neuroscience knowledge can benefit laypeople as well as professionals in many different areas, it may be particularly relevant for educators. With the right information, educators can apply neuroscience-based teaching strategies as well as protect themselves and their students against pseudoscientific ideas and products based on them. Despite rapidly growing sources of available information and courses, studies show that educators in many countries have poor knowledge of brain science and tend to endorse education-related neuromyths. Poor English skills and fewer resources (personal, institutional and governmental) may be additional limitations in Latin America. In order to better understand the scenario in Latin America's largest country, we created an anonymous online survey which was answered by 1634 individuals working in education from all five regions of Brazil. Respondents stated whether they agreed with each statement and reported their level of confidence for each answer. Significant differences in performance were observed across regions, between educators living in capital cities versus the outskirts, between those teaching in private versus public schools, and among educators teaching different levels (pre-school up to college/university). We also observed high endorsement of some key neuromyths, even among groups who performed better overall. To the best of our knowledge, this is the first study to conduct a detailed analysis of the profile of a large group of educators in Brazil. We discuss our findings in terms of efforts to better understand regional and global limitations and develop methods of addressing these most efficiently.

Research in education and communication in science: contributions from the Biota-Fapesp program to biodiversity education / Pesquisa em educação e comunicação em ciências: contribuições do programa Biota-Fapesp para a educação em biodiversidade

Abstract In this article, we aim to understand the contributions of the Biota-Fapesp Program to the research in biodiversity education and communication. Our research questions are: (i) is the Biota-Fapesp Program following or contributing to the significant advances in conceptual, technological/methodological, and management/governance aspects of biodiversity education/communication research?; (ii) if yes, how do the projects contribute to these advances?; and (iii) what are the main expectations for the future of Biota in education and communication research? Our analyzes highlighted a qualitative contribution from the Biota-Fapesp Program at institutional, methodological, conceptual, and educational levels. However, due to the few projects, it can be considered a summative contribution and not a transformative one. Perspectives for the Biota-Fapesp Program in these areas were divided into three approaches: 1. Research lines and concepts that could be encouraged through specific calls or inclusion in other calls of interest to the Program; 2. Innovative methodological approaches for the area that should be encouraged; 3. Suggestions for scientific research management and infrastructure. Through data and discussions presented below, we hope to contribute to the understanding of the role of Biota-Fapesp in the area, and point out ways to develop research, practices and public policies that promote the strengthening of science as culture.

Nossas análises destacaram uma contribuição qualitativa do Programa Biota-Fapesp nos níveis institucional, metodológico, conceitual e educacional. No entanto, devido ao baixo número de projetos, esta contribuição pode ser considerada somativa, mas não transformadora. As perspectivas do Programa Biota-Fapesp para essas áreas foram divididas em três abordagens: 1. Linhas de pesquisa e conceitos que podem ser incentivados por meio de editais específicos ou inclusão em outros editais de interesse do Programa; 2. Abordagens metodológicas inovadoras para a área que devem ser incentivadas; 3. Sugestões para gestão e infraestrutura da pesquisa científica. Por meio dos dados e discussões apresentados a seguir, esperamos contribuir para a compreensão do papel do Biota-Fapesp na área, bem como apontar caminhos para desenvolver pesquisas, práticas e políticas públicas que promovam o fortalecimento da ciência como cultura.

Connecting the Dots Among Science, Education, and STEM.

Makerspaces, Innovation and Science Education: How, Why, and What For? is an attempt to interrogate questions about the history, philosophy, and sociology of science and schooling that have long troubled science educators. In crafting the book, the author, Michael Tan, uses the microcosm of makerspaces to move back and forth to interrogate questions about the nature of knowledge, nature of science, nature of pedagogy, and nature of schooling best suited for the times we live in. In the seven chapters that comprise the book, the author has worked out a consistent framework to answer these questions. This framework represents a strong academic opinion that is thought provoking.

L'ouvrage intitulé « Makerspaces, Innovation and Science Education: How, Why, and What For? (Laboratoires ouverts, innovation et enseignement des sciences: comment, pourquoi et dans quel but ?)¼ tente d'obtenir des réponses aux questions portant sur l'histoire, la philosophie et la sociologie des sciences ainsi que sur l'enseignement qui ont longtemps tourmenté les éducateurs scientifiques. Dans l'élaboration de son livre, Michael Tan, utilise le microcosme des laboratoires ouverts pour aller et venir en s'interrogeant sur la nature de la connaissance, celle de la science, la nature de la pédagogie et celle de la scolarisation qui sont les mieux adaptées à l'époque dans laquelle nous vivons. Dans les sept chapitres qui composent le livre, l'auteur élabore un cadre cohérent pour répondre à ces questions. Ce cadre forme une opinion théorique forte qui suscite la réflexion.

A critical perspective on pandemics and epidemics: building a bridge between public health and science education.

This academic position paper focuses on building a bridge between public health and science education in order to recognize the relationships between science and society-politics, economics, and ideology-in a pandemic context. To do this, we first present the contemporary dispute between the ways of understanding and explaining public health problems in light of a historical-territorial critical perspective; then, we show the configuration process of the formal and hegemonic concept of pandemic that has taken place over the period of the pandemics of the 1918 flu and the 2019 coronavirus disease; later, we give way to a historical-territorial understanding of the genesis of the 2002 and 2012 epidemics in relation to the coronavirus in the twenty-first century; and lastly, we indicate the key points from the historical-territorial critical perspective of public health that science education can use in order to contribute to a critical and reflective understanding of epidemics and pandemics. In this framework, "configuration process" is a category we propose and use in order to explain that specific events such as epidemics and pandemics are interwoven in a social, historical-territorial, trajectory of world power relations.

Este documento de posición académica, titulado «Una perspectiva crítica de las pandemias y las epidemias: construyendo un puente entre la salud pública y la educación científica¼, se enfoca en la construcción de un puente entre la salud pública y la educación científica que tiene por objeto reconocer las relaciones que existen entre la ciencia y la sociedad ­esto es, entre la ciencia y la política, la ciencia y la economía, y la ciencia y la ideología­ en un contexto de pandemia. Para ello, después de ofrecer una necesaria introducción, se presenta en la primera parte, y a la luz de una perspectiva crítica histórico-territorial, la disputa contemporánea entre las formas de entender y explicar los problemas de salud pública. Esta disputa se presenta en dos subtítulos, uno denominado «De la teoría del germen a la biomedicina¼, y otro denominado «De la perspectiva sociohistórica a la perspectiva histórico-territorial¼. En la segunda parte se expone el proceso de configuración del concepto de «pandemia¼ que, formal y hegemónico, ha tenido lugar entre la pandemia de gripe de 1918, declarada por el Ministerio de Salud de Inglaterra y Gales en 1920, y la pandemia de la enfermedad por coronavirus de 2019, declarada por la Organización Mundial de la Salud en 2020 el mismo año. En la tercera parte, la denominada «Crónica de una pandemia anunciada en tiempos del capitalismo neoliberal¼, se presenta una comprensión, de perspectiva histórico-territorial, sobre la génesis de las epidemias que estuvieron relacionadas con coronavirus en los años 2002 y 2012. Con el ánimo de mostrar la similitud encontrada entre las génesis de las epidemias de 2002 y 2012, el apartado dedicado a la epidemia de 2002 se subtitula «Un mercado de animales salvajes en la génesis de la epidemia del Síndrome Respiratorio Agudo Severo (SARS)¼, y el dedicado a la epidemia de 2012, «Un mercado de animales domesticados en la génesis de la epidemia del Síndrome Respiratorio de Oriente Medio (MERS)¼. Finalmente, en la última parte, se señalan asuntos clave de la perspectiva crítica histórico-territorial de la salud pública que la educación científica puede utilizar para contribuir a una comprensión crítica y reflexiva de las epidemias y pandemias. En este marco, «proceso de configuración¼ es una categoría que se propone y utiliza para explicar que acontecimientos concretos, como las epidemias y las pandemias, están entretejidos en una trayectoria social de relaciones mundiales de poder, que es histórico-territorial.

Mexican Educators Survey on Anatomical Sciences Education and a Review of World Tendencies.

Anatomical sciences curricula have been under constant reform over the years, with many countries having to reduce course hours while trying to preserve laboratory time. In Mexico, schools have historically been autonomous and unregulated, and data regarding structure and methods are still lacking. A national survey was sent by the Mexican Society of Anatomy to 110 anatomical sciences educators. The questionnaire consisted of 50 items (open and multiple choice) for gross anatomy, microscopic anatomy, neuroanatomy, and embryology courses in medical schools across Mexico. A clinical approach was the most common course approach in all disciplines. Contact course hours and laboratory hours were higher in Mexican anatomy education compared to other countries, with the highest reported contact hours for embryology (133.4 ± 44.1) and histology (125 ± 33.2). There were similar contact hours to other countries for gross anatomy (228.5 ± 60.5). Neuroanatomy course hours (43.9 ± 13.1) were less than reported by the United States and similar to Saudi Arabia and higher than the United Kingdom. Dissection and microscopy with histological slides predominate as the most common laboratory activities. Traditional methods prevail in most of the courses in Mexico and only a few educators have implemented innovative and technological tools. Implementation of new methods, approaches, and curricular changes are needed to enhance anatomical sciences education in Mexico.

A Simple and Low-Cost, but Naturalistic Method for Introducing Students to Action Potentials

Abstract Current trends in science education recommend the complementary use of virtual and hands-on methods of teaching. In neurobiology, for instance, there is a plethora of virtual laboratories and simulators that can be readily combined with traditional physical labs. Unfortunately, physical laboratories are almost unaffordable for many institutions due to the high cost of equipment. In this paper, we present a simple and low-cost in vivo method for demonstrating some of the basic biophysical properties of neural action potentials. The method involves the following steps: a) dissection of the ventral nerve cord of earthworm; b) electrical stimulation; c) amplification and visualization of the medial and lateral giant fibers' action potentials; and d) recording. The system showed stability, expected amplification, high signal-to-noise ratio, and an estimated total cost of US$ 5.662. We provide guidelines for assembling the system and discus its utility as a teaching alternative for low budget institutions.

Aprendizaje interprofesional en los internados de las carreras de la salud del Hospital Josefina Martínez / Interprofessional learning of interns at Josefina Martínez Hospital

Introducción: las dinámicas de atención en salud requieren que los profesionales que componen el equipo de salud trabajen en for-ma colaborativa. Sin embargo, durante su formación, las oportunidades de aprendizaje con otras disciplinas son escasas. Se reportan los resultados del primer proyecto para promover el aprendizaje interprofesional en los internos que rotan por el Hospital Josefina Martínez. Método: de marzo a julio 2018, se realizó un taller constituido por dos sesiones, en cada rotación de internado. Participaron internos de cinco carreras en forma conjunta (kinesiología, odontología, nutrición, fonoaudiología y terapia ocupacional). Se adaptó la encuesta de disposición al aprendizaje interprofesional, para ser aplicada antes y después de cada taller. Se calcularon las medianas, rangos intercuartílicos (Q1; Q3y se compararon los puntajes mediante test de Wilcoxon. Resultados: hubo una disposición positiva inicial al aprendizaje interprofesional, con mejoría significativa después de los talleres en todas las dimensiones de la encuesta: Trabajo en equipo y colaboración (<0,001), trabajo centrado en el paciente (<0,001), y sentido de identidad profesional (<0,05). La diferencia del puntaje global de la encuesta también fue significativa (<0,001). Conclusiones: se demostró un cambio favorable y significativo en las respuestas de los internos después de los talleres, en todas las dimensiones de la encuesta. En los comentarios, destacaron la relevancia de aprender con estudiantes de otras carreras, describiendo que aumentó su conocimiento sobre éstas y reforzando el impacto que dicha integración tiene en mejorar la atención y resolución de problemas en salud.

Background: The dynamics of health care require that the health professionals work collaboratively; however, during their training, learning opportunities with other disciplines are infrequent. The results of the first project to promote interprofessional learning in the clinical internship at Hospital Josefina Martínez are reported. Methods: From March to July 2018, two workshops for each internship rotation were carried. Students from fivecareers participated together (Kinesiology, Dentistry, Nutrition, Speech Therapy, and Occupa-tional Therapy). The readiness to interprofessional scale survey was adapted, to be applied before and after each workshop. Medians, interquartile range (Q1; Q3) were calculated, and the Wilcoxon test was used to compare the results. Results: There was an initial po-sitive readiness for interprofessional learning, with a significant improvement in all the dimensions of the survey, after the workshops: Teamwork and collaboration (<.001), patient-centered care (<.001), and sense of professional identity (<.05). The differences from the overall survey were also significant (<0.001). Conclusions: A favorable change was demonstrated in the responses of the students after the workshops, overalland in all the dimensions of the survey. In the comments, the students highlighted the relevance of learning with students from other careers, describing that it increased their knowledge about different professions and strengthening the impact that this integration has in improving attention and resolving health problems.

Reconstrução e impressão 3D do neurocrânio de cão com o uso de tomografia computadorizada como ferramenta para auxiliar no ensino da anatomia veterinária / [Reconstruction and three-dimensional printing (3D) of the neurocranium of a dog from computed tomography used as a tool for anatomy veterinary teaching]

A impressão tridimensional (3D) vem contribuindo para o aprendizado da anatomia e para áreas aplicadas da medicina veterinária utilizando uma interface que pode valorizar o conhecimento da anatomia das espécies domésticas de maneira dinâmica. O presente trabalho objetivou utilizar imagens tridimensionais geradas por tomografias computadorizada (TC) para a obtenção de imagens digitalizadas e de modelos de ossos do crânio de cão por meio de uma impressora tridimensional. Foram gerados arquivos 3D de TC a partir de imagens que foram editadas pelo software Osirix Lite. Partes dos ossos e particularidades anatômicas do crânio foram impressas em escalas de 60% e 100%. Os resultados permitiram gerar imagens digitalizadas e impressões tridimensionais advindas das tomografias, e, assim, foi criado um acervo de imagens e modelos impressos para os estudos da anatomia do crânio da espécie canina. Além disso, a metodologia demonstrou claramente a importância para uso de planejamentos cirúrgicos nos casos de procedimentos que envolvam comprometimento de estruturas ósseas. Produziu-se um material interativo e impresso em 3D com maior durabilidade, o qual poderá ser disponibilizado para fins educacionais.(AU)

The three-dimensional printer (3D) has been contributing to the learning of anatomy and applied areas of veterinary medicine using an interface that can enhance the knowledge of the anatomy of domestic species in a dynamic way. The present study aimed to use three-dimensional images generated by computed tomography (TC) to obtain digitized images and bone models of the dog skull using a three-dimensional printer. The 3D files were generated from images that were edited in Osirix Lite software. Parts of the bones and anatomical features of the skull were printed on 60% and 100% scales. The results allowed to generate digitalized images and three -dimensional impressions from the tomographies, and in this way a collection of images and printed models was created for studies of the anatomy of the canine species. In addition, the methodology clearly demonstrated the importance of using surgical planning in cases involving procedures involving bone structure impairment. Interactive material and 3D printing with high durability that could be made available for educational purposes has been produced.(AU)

Partnering ethics and chemistry in secondary and university STEM education via an innovatively designed periodic table of chemical elements / Ética y química asociadas en la educación secundaria y universitaria STEM, a través de una tabla periódica de elementos químicos de diseño innovador / Associando ética e química na educação stem secundária e universitária via uma tabela periódica de elementos químicos desenvolvida de forma innovadora

As declared by the United Nations, 2019 is the International Year of the Periodic Table of Chemical Elements. Accordingly, an innovative new Periodic Table of Chemical Elements and Ethics [PETE] has been developed as an educational tool for secondary and university STEM (Science, Technology, Engineering and Mathematics) education. The tool is designed to be used in a case-based approache that is feasible to both individual and small group learners. Specifically, with the new periodic table, STEM becomes aligned with STSE (Science and Technology on Society and Environment), laying a curricular pathway for integrating discussions of ethics into the teaching of chemistry. Presented is the table, as well as sources for pairable ethics cases, and guidance for teachers to create curriculum which facilitates connections between ethics, chemistry, and society.

Según lo declarado por las Naciones Unidas, 2019 es el Año Internacional de la Tabla Periódica de Elementos Químicos. En consecuencia, se ha desarrollado una nueva e innovadora tabla periódica de elementos químicos y ética [PETE] como una herramienta educativa para la educación secundaria y universitaria STEM (Ciencia, Tecnología, Ingeniería y Matemáticas). La herramienta está diseñada para usarse en un enfoque basado en casos que sea factible tanto para estudiantes individuales como para grupos pequeños. Específicamente, con la nueva tabla periódica, STEM se alinea con STSE (Ciencia y Tecnología en Sociedad y Medio Ambiente), estableciendo una vía curricular para integrar las discusiones de ética en la enseñanza de la química. Se presenta la tabla, así como las fuentes de casos de ética que se pueden pactar, y orientación para que los maestros creen un plan de estudios que facilite las conexiones entre la ética, la química y la sociedad.

Como declarado pelas Nações Unidas, 2019 é o Ano Internacional da Tabela Periódica de Elementos Químicos. Portanto, uma inovadora e nova Tabela Periódica de Elementos Químicos e Ética (PETE, sigla em inglês) foi desenvolvida como uma ferramenta educacional para educação STEM (sigla em inglês para Ciência, Tecnologia, Engenharia e Matemática) secundária e universitária. A ferramenta é elaborada para ser usada em uma abordagem baseada em casos, viável tanto para aprendizagem individual como de pequenos grupos. Especificamente, com a nova tabela periódica, STEM se alinha com STSE (sigla em inglês para Ciência e Tecnologia na Sociedade e Ambiente), estabelecendo uma via curricular para integrar discussões de ética no ensino de química. Apresenta-se a tabela, bem como fontes de casos éticos pareados, e orientação para professores criarem um currículo que facilite conexões entre ética, química e sociedade.

La regionalización y la educación bibliotecológica universitarias en Costa Rica: ¿una coincidencia o un cincuentenario convenido? / Regionalization and university library education in Costa Rica: a coincidence or an agreed fiftieth anniversary?

RESUMEN Este ensayo plantea cómo la regionalización de la educación superior y la formación universitaria en Bibliotecología en Costa Rica coinciden al aparecer en un momento histórico en el que la educación se convirtió en una pieza angular del desarrollo nacional. A partir de una revisión e interpretación de los hechos dados entre 1967 y 1997, se concluye que la conjunción de voluntades generadas más de dos décadas después de ocurridos ambos acontecimientos, sirvieron para reconocer el papel que ha jugado la regionalización en el desarrollo de la profesión en las regiones. Este nacimiento de ninguna manera fue una convención, sino, más bien, una hermosa coincidencia guiada por las necesidades del desarrollo nacional de la época.

ABSTRACT This essay proposes how the regionalization of higher education and university education in librarianship in Costa Rica coincide when they appear at a historical moment in which education became an angular piece of national development. From a review and interpretation of the events that occurred between 1967 and 1997 it is concluded that the conjunction of wills that occurred more than two decades after served to recognize the role that has played regionalization in the development of the profession in the Costarican regions. This birth was in no way a convention but a beautiful coincidence guided by the the national development needs.
