Introducción: la formación y competencia investigativa durante el pregrado constituye una necesidad sentida en la universidad moderna.Objetivo: caracterizar la autopercepción de habilidades investigativas por miembros de grupos científicos estudiantiles en tres universidades médicas cubanas.Métodos: estudio observacional, descriptivo y transversal a miembros de los grupos científicos estudiantiles de las Universidades de Ciencias Médicas de las provincias de Pinar del Río, Cienfuegos y Holguín, entre enero y marzo de 2020. La población de la constituyeron 74 estudiantes. Se empleó estadística descriptiva y la prueba Kruskal-Wallis para variables ordinales.      Resultados: se identificó como habilidades más afectadas la selección y aplicación de métodos estadísticos (inadecuados = 39,19 %) y la selección, elaboración y aplicación de métodos, técnicas e instrumentos (inadecuados = 27,03 %). El 71,62 % percibieron como inadecuadas sus habilidades en el manejo de sistemas de gestión editorial y el 66,22 % en el empleo de gestores de referencias. Se encontró asociación (p<0,05) entre habilidades investigativas y el año académico. Se encontró asociación entre las habilidades en el manejo de las tecnologías de la información y las comunicaciones, el uso de programas estadísticos y la exposición de resultados mediante el multimedia, con el año académico (p<0,01)Conclusiones: existe un déficit percibido entre los estudiantes en sus habilidades investigativas y del manejo de las tecnologías de la información y las comunicaciones, centradas principalmente en la estadística, sistemas estadísticos y gestores de referencia, así como en la selección y elaboración de métodos y la presentación de la información.

Introducción: en el caso de la odontología, la bioseguridad se centra en los procedimientos que se deben seguir dentro del consultorio odontológico con el fin de garantizar la salud y seguridad tanto del odontólogo y sus asistentes, como del paciente. Estos procedimientos de Bioseguridad en odontología involucran estrategias de inmunización y también la prevención de la exposición de dentistas, asistentes y pacientes a materiales infecciosos.Objetivo: describir los cambios en las medidas de bioseguridad en la odontología a nivel mundial determinados por la detección del virus SARS-CoV-2.Métodos: para realizar esta investigación se consultaron 27 artículos sobre el tema, obtenidos de búsquedas en bases de datos como Elsevier a través de Science Direct, Google Académico yScielo, de ellos fueron utilizados 14 como bibliografía. Predominaron los artículos publicados durante los últimos cinco años y otros por su relevancia.Desarrollo: los protocolos de bioseguridad antes de la aparición del Covid-19 estaban enfocados en evitar accidentes laborales, enfermedades propias de la profesión e infecciones cruzadas. El lavado de manos se difundía para los profesionales de la salud y para la población en general no era muy común. Luego de la detección del Covid-19 se mejoraron las condiciones de limpieza y bioseguridad dentro de la práctica odontológica, pacientes más informados, personal de limpieza eficaz, normas obligatorias lavado de manos, toma de temperatura, instrumental para cada paciente, normas estrictas de esterilización y limpieza de áreas de forma general.Conclusiones: antes de realizar un tratamiento el paciente se debe enjuagar la boca durante un minuto por peróxido de hidrógeno al 0,5 % o 1 % (tener precaución al prepararlo para evitar quemaduras en mucosa) o con Povidona al 0,2 % (tener cuidado con alérgicos a yodo).

¿La Maestría en Medicina Natural en la Atención Integral al Paciente desarrolla competencias investigativas?

The teaching of sexuality is cited as necessary in the school environment, especially in early childhood education, being an important theme to be developed with children. Nevertheless, there is resistance from families, education professionals, religions, and political obstacles to addressing this issue. This study sought to explore the personal view of education professionals on sexuality and gender diversity and their teaching in the school environment. Descriptive qualitative research was performed using semi-structured data. The public analyzed is conservative and tends to reflect on the teaching and transmission of information about sexuality and gender diversity in the school environment. We concluded that the way of thinking about sexuality must be changed in the academic, family, religious, and political environments and that the school must provide opportunities for situations involving guidance on the subject.

Science Teaching in Early Childhood Education has conquered an important space in research and teaching practices, creating new ways of planning children's education. In this article, the goal was to study the ways how recreational activities in a "Science, Technology and Society (CTS in Portuguese Abbreviation) Approach" improve Science Teaching in an Early Childhood Education class, aiming at the formation of adult citizens. The research approach was qualitative, of the "pedagogical intervention" type. As an intervention method, recreational activities were used. The research subjects were 21 children, between four and five years old, from an Early Childhood Education School in Belém/PA. It was observed through the analysis that playfulness encouraged the observation of the school environment by children, enhancing their imaginations and creativity, by assuming different roles, creating hypotheses for school problems and exposing their opinions using different languages. In conclusion, recreational activities meet the needs of developing children, promoting meaningful learning and positive consequences for their formal education.

In the pandemic context of COVID-19, the definition of social isolation led to the closure of Higher Education Institutions, a situation that made them adopt the Emergency Remote Teaching (ERT). Due to that, professors and students were called to continue academic activities in a different context from the in-person learning, causing significant modifications in teaching-assessment-learning processes. This paper, coming from a qualitative investigation, of an interpretative nature, aimed to analyze the perception of pre-service Mathematics teachers on the assessment of learning conducted in the disciplines taken during 2020/2021. Through the Discursive Textual Analysis (DTA), the analysis of the statements collected in an online questionnaire revealed: a) the relationship between the teaching-assessment-learning processes experienced during the ERT; b) the referrals and instruments used by professors to evaluate learning in the ERT; c) the conditions and knowledge necessary to monitor the classes and perform the evaluative activities in the ERT.

This article presents the results of the search and analysis of articles, theses and dissertations published in Academic-Scientific Periodicals and in the Brazilian Digital Library of Theses and Dissertations that deal with the construction and use of 3D Virtual Worlds (MV3D) in the educational field, with a focus on in Physics teaching. Through the literature review, guided by the Systematic Literature Review procedure, a total of 16 works were selected for the sample. As a result, an overview of the area was obtained, with an indication of the main characteristics of the studies, such as contents and platforms used in the development of MV3D, as well as contributions and potentialities in the teaching and learning process of Physics. Among them, the adequate use of three-dimensional technology resources stands out, reproducing with quality the real environments in a virtual world, allowing the association with the student's reality in a motivational perspective.

This study aims to investigate the contributions of an extension course on Teaching by Investigation (TI) and investigative experimentation for the training of undergraduates in Chemistry. The present qualitative study involved six second-year students from a public university in the state of Paraná (Brazil), who developed various activities, among them, answering questionnaires, participating in debates, reading and discussing texts, visiting research laboratories, conducting experiments and redesigning traditional experimental guidelines with a view to an investigative approach. The data collected by means of audio recording, observations and field notes were analyzed using Discursive Textual Analysis (DTA). The results highlighted that the activities developed in the context of the extension course promoted student dialog and reflection of graduates as regards TI, investigative experimentation and the importance of these approaches in Chemistry Teaching.

The practical classes in botany increase student´s interest in the subject, which is considered difficult to assimilate. However, due to the pandemic, this system had to be adapted. We propose the use of botany illustrations boards for the identification of species families, as an alternative to practical approach in classes of Plant Systematics. The boards contained drawing of structures, a diagram and floral formula representative for the families. We also provide the students with a glossary for botanical terms and bibliography. Initially, many students found the activity difficult, however after follow-up, all were able to complete the task successfully. This showed that they already had the knowledge to carry out the proposal, but for fear of making mistakes, avoided trying. We believe that this model can increase learning, provides practical approaches in online teaching and can serve as an alternative for moments/places where practice is not an option.

The History of Science, considered from the STS perspective, can be one of the ways to approach scientific knowledge in a contextualized way, in activities that stimulate Critical Thinking.  This study aims to investigate and characterize national research, within the scope of Science teaching, which is based on the History of Science approach for the development of Critical Thinking in theoretical propositions or didactic strategies.  The methodological course highlights the stages of Content Analysis in the bibliographic research.  Seventeen articles were analyzed, and only five articles consider Critical Thinking as an object of study of their approaches, which means a smaller number of publications compared to twelve works that present Critical Thinking as a general quality.  These results show the necessary systematization of the proposals in a specific literature, so that the historical approaches develop Critical Thinking in the midst of the acquisition of scientific knowledge.
