Advancing E-Mental Health in Canada: Report From a Multistakeholder Meeting (Preprint)
Authors: Strudwick Gillian , Impey Danielle , Torous John , Krausz Reinhard Michael , Wiljer David
Published: April 2020

UNSTRUCTURED

The need for e-mental health (electronic mental health) services in Canada is significant. The current mental health care delivery models primarily require people to access services in person with a health professional. Given the large number of people requiring mental health care in Canada, this model of care delivery is not sufficient in its current form. E-mental health technologies may offer an important solution to the problem. This topic was discussed in greater depth at the 9th Annual Canadian E-Mental Health Conference held in Toronto, Canada. Themes that emerged from the discussions at the conference include (1) the importance of trust, transparency, human centeredness, and compassion in the development and delivery of digital mental health technologies; (2) an emphasis on equity, diversity, inclusion, and access when implementing e-mental health services; (3) the need to ensure that the mental health workforce is able to engage in a digital way of working; and (4) co-production of e-mental health services among a diverse stakeholder group becoming the standard way of working.
The Role of YouTube and the Entertainment Industry in Saving Lives by Educating and Mobilizing the Public to Adopt Behaviors for Community Mitigation of COVID-19: A Successive Sampling Design (Preprint)
Authors: Basch Charles E , Basch Corey H , Hillyer Grace C , Jaime Christie
Published: April 2020

BACKGROUND

Effective community mitigation through voluntary behavior change is currently the only way to reduce mortality caused by COVID-19. This study builds on our prior study based on the scientific premise that YouTube is one of the most effective ways to communicate and mobilize the public in community mitigation to reduce exposure to SARS-COV-2.

OBJECTIVE

Because of the rapidly changing nature of YouTube in the context of the COVID-19 pandemic, we conducted a follow-up study to document how coverage of preventive behaviors for effective community mitigation have changed.

METHODS

A successive sampling design was used to compare coverage of behaviors to mitigate community transmission of COVID-19 in the100 most widely viewed YouTube videos in January 2020 and March 2020.Videos in the two samples were viewed > 125 million times and >355 million times, respectively. Fewer than one-half of the videos in the March sample covered any of the prevention behaviors recommended by the U.S. Centers for Disease Control and Prevention, but many covered key prevention behaviors and were very widely viewed. There were no videos uploaded by entertainment television in the January sample but this source comprised the majority of videos and garnered the majority of cumulative views in the March sample.

RESULTS

Videos in the two samples were viewed > 125 million times and >355 million times, respectively. Fewer than one-half of the videos in the March sample covered any of the prevention behaviors recommended by the U.S. Centers for Disease Control and Prevention, but many covered key prevention behaviors and were very widely viewed. There were no videos uploaded by entertainment television in the January sample but this source comprised the majority of videos and garnered the majority of cumulative views in the March sample.

CONCLUSIONS

This study demonstrates the incredible reach of YouTube and the potential value of partnership with the entertainment industry for communicating and mobilizing the public about community mitigation to reduce mortality from the COVID-19 viral pandemic.
Making sense of the Global Coronavirus Data: The role of testing rates in understanding the pandemic and our exit strategy (Preprint)
Authors: Potluri Rahul , Lavu Deepthi
Published: April 2020

BACKGROUND

The Coronavirus disease 2019(COVID-19) outbreak has caused havoc across the world. Subsequently, research on COVID-19 has focused on number of cases and deaths and predicted projections have focused on these parameters. We propose that the number of tests performed is a very important denominator in understanding the COVID-19 data.

OBJECTIVE

We analysed the number of diagnostic tests performed in proportion to the number of cases and subsequently deaths across different countries and projected pandemic outcomes.

METHODS

We obtained real time COVID-19 data from the reference website Worldometer at 0900 BST on Saturday 4th April, 2020 and collated the information obtained on the top 50 countries with the highest number of COVID 19 cases. We analysed this data according to the number of tests performed as the main denominator. Country wise population level pandemic projections were extrapolated utilising three models - 1) inherent case per test and death per test rates at the time of obtaining the data (4/4/2020 0900 BST) for each country; 2) rates adjusted according to the countries who conducted at least 100000 tests and 3) rates adjusted according to South Korea.

RESULTS

We showed that testing rates impact on the number of cases and deaths and ultimately on future projections for the pandemic across different countries.

CONCLUSIONS

We found that countries with the highest testing rates per population have the lowest death rates and give us an early indication of an eventual COVID-19 mortality rate. It is only by continued testing on a large scale that will enable us to know if the increasing number of patients who are seriously unwell in hospitals across the world are the tip of the iceberg or not. Accordingly, obtaining this information through a rapid increase in testing globally is the only way which will enable us to exit the COVID-19 pandemic and reduce economic and social instability.

“A” for Attitude—Attitudes towards Dyslexia in Higher Education
Authors: P. Beckett Jonathan , A. Darnell Judith
Published: April 2020

This paper makes the case for the importance of an empathetic approach to understanding dyslexia, in educational establishments, especially in Higher Education. An awareness of the implications that having dyslexia and how this affects both study skills (concentration, organisation, revision and so forth) and presentation skills (completion of assignments within academic language and structures and without grammar, punctation and spelling errors) is accentuated in this article.This research employs meta-ethnography, the Critical Appraisal Skills Programme (CASP) and a grounded theory overlay to thematic critical analysis. In so doing, UK literature of both quantitative and qualitative format was examined through specifying inclusion criteria and using a filtering approach.The justification for this work is to challenge any institutional or individual indirect discriminatory practice towards students with dyslexia.Conclusions indicate the need for enhanced institutional understanding of dyslexia and associated provision for individual dyslexic learners within Higher Education in its entirety. For example, access to digitalised resources, individual tutorials, assistive technology and adjusted expectations in marking criteria (as not to penalise for issues concomitant with dyslexia).
THE SOCIAL EXCLUSION OF PERSONS WITH DISABILITIES FROM TERTIARY EDUCATION – TARGETING BARRIERS DEPENDING ON THE TYPE OF DISABILITY BASED ON THE FINDINGS OF A QUALITATIVE STUDY
Authors: Nikolajević Aleksandra
Published: April 2020

In this paper, we primarily dealt with the low representation of persons with disabilities in the tertiary education system and targeted specific barriers that keep people with disabilities outside the tertiary education process. The mentioned problem was approached from the perspective of social exclusion and one of the main tasks of the conducted research was to gain insight into the types of barriers that affect persons with different types of disabilities depending on their student status (they did not enroll at a university, they discontinued their studies, they are currently studying, they have completed their studies). The results were gained by conducting in-depth interviews covering all the mentioned categories of persons with disabilities. The results of the research point to the existence of numerous obstacles that people with disabilities face in the process of acquiring tertiary education. It has turned out that the surveyed persons with disabilities face insurmountable obstacles in the form of architectural, institutional and social barriers, depending on the type of disability and their social environment.
VALUES AND VALUE SHIFTS IN FOUR COUNTRIES OF SOUTH-EAST EUROPE: RETRADITIONALIZATION, EROSION OF TRUST AND THE DECLINE IN PUBLIC MORALITY
Authors: Lavrič Miran , Gavrilović Danijela , Puzek Ivan , Klanjšek Rudi
Published: April 2020

The paper considers the values and value orientations in four ex-Yugoslav republics (Bosnia and Herzegovina, Serbia, Croatia, and Slovenia). The starting point of the analysis are cross-national analyses of data from the World values survey (Inglehart et al.2014) and data presented by Shalom Schwartz (2013). Both approaches paint a similar picture of Slovenia being by far the closest to values typical for Western liberal democracies, while Bosnia and Herzegovina, and partially Serbia, are found on the opposite extreme. The longitudinal analyses suggest that in all the countries the studied values shifted in the direction of more traditional and survival values. More specifically, all four countries have witnessed an erosion of generalised social trust, a decline in public morality, and retraditionalization of gender roles. It is argued that these shifts should mainly be understood as a consequence of the enduring economic insecurities of the citizens, enhanced by the effects of the global economic crisis.
ATTRIBUTIONS TO ACADEMIC SUCCESS AND FAILURE AND THE STRATEGIES FOR DEALING WITH THE EXAMINATION SITUATION AS PREDICTORS OF ACADEMIC SUCCESS
Authors: Đigić Gordana , Zdravković Milica
Published: April 2020

The study was aimed at investigating students’ attributions to academic success/failure and the strategies for dealing with the examination situation as predictors of academic success. Students’ attributions to academic success/failure by internal/external and stable/unstable causes were examined by the Scale of Attributions to Academic Success and Failure. The strategies for dealing with the examination situation (focusing on the problem, focusing on emotions, imagination/distraction, seeking help in the examination situation) were examined by the Scale of Dealing with Examination Situation. The results obtained on the sample of second grade grammar school students (N=204) show that students’ attributions to academic success/failure and the strategies of dealing with the examination situation explain a significant percent of variance in academic success (R²=.210, p=.000). The most important particular predictor is the strategy of dealing with the examination situation by focusing on the problem (β=.244, p=.005). Students’ attributions to failure are more important predictors of academic success than attributions of success. Differences between boys and girls in the patterns of particular predictors of academic success were found. The results point out that it is important to support constructive students’ styles of attributions to academic success/failure and the strategies for dealing with examination situations.

Authors: Tošić Radev Milica , Bogdanović Aleksandra , Anđelković Vesna
Published: April 2020

This study aimed to test the model set up by Obradović and Čudina-Obradović, according to which marital quality is determined by certain traits of marital quality from each of these groups of factors: the personality traits of the partners, the characteristics of the marriage, the marital processes and the marital environment. We operationalized this model, by testing the effect personality traits and the tendency towards alcohol consumption of marriage partners (as a personal characteristic of the marriage partner), the duration of the marriage (as the characteristic of the marriage itself), satisfaction with the division of household responsibilities (as one of the indicators of the development of the marital processes) and doubt regarding the marriage partner's fidelity (as the feature of the wider marital environment) have on the experienced marital quality. NEO-PI-R, The Dyadic Adjustment Scale and questionnaire designed for the aims of this study were used on a sample of 199 respondents from Serbia. Our model shows an excellent fit (X2 >.05; RMSEA<.05; GFI>.90; AGFI>.90; CFI>.90; NFI>.90). It can be concluded that Neuroticism, The Duration of marriage, Doubt regarding the partner’s fidelity and Dissatisfaction with the division of household responsibilities have a negative effect on marital quality.

Published: April 2020

The paper presents the results of research on the achievements of the third and fourth grade of primary school students in relation to the requirements of the objectives and learning outcomes given in the Mathematics Curriculum for Primary School. In order to examine the achievements of students, i.e. the level of achievement of objectives about natural numbers, a taxonomic model of operationalization of the goal and objectives of teaching mathematics was used. The survey was conducted on a sample of 341 students of the third and 315 students of the fourth grade in three Primary Schools in the population of students of the third and fourth grades of primary schools in Pčinja District in Serbia. A descriptive method was used in all its variants: analytical, comparative and classificational, and in accordance with that the analysis technique and testing of the content was applied. As an instrument, criterion-referenced tests were created for the purpose of research, which determined what and to what level of knowledge in terms of quality were the students acquired from what was planned.The obtained results indicate that the students did not achieve the most of objectives given in the Mathematics Curriculum, considering the quality of knowledge they include, which was determined on the basis of an analysis of the requirements of objectives and learning outcomes and in accordance with categories of knowledge of given taxonomic model.The results of this theoretical-empirical research can contribute to changes in the approach to teaching contents: in changing and innovating the mathematics curriculum, in presenting the content of the program; the operationalization of the goal and objectives; the quality of evaluating and assessing student achievement; validity and quality of tests of knowledge and skills, and others.
HOW TO RECOGNISE AND MANAGE PATOLOGICAL NARCISSISM IN CHILDHOOD?
Authors: Ristić Milica , Mitrović Milica
Published: April 2020

This paper represents an attempt to answer some questions that concern pathological narcissism in childhood. Specifically, which are some of the possible causes of pathological narcissism, where are the limits of normal and pathological narcissism, what are the manifestations of its pathological form in childhood and also eventual strategies for its management. Theorists and clinicians in this area agree that the narcissism represent the normal phase in child development. On the other hand, pathological form of narcissism also has its origins in the earliest period of one’s life (even as early as 7 or 8 years of life) and it can be rooted in broad spectre of dysfunctional interactions with parents. Pathological narcissism can be reflected through the idea that child is really superior to others and beyond criticism and failure, grandiose view of himself/herself, through excessive demands that parents cannot meet. One of typical manifestation is inability to sustain efforts at school or during the activities involving learning new skills. Beside parents, teachers can and must be involved in the processes of identification and application of interventions oriented toward correction of problematics behaviour.

Published: April 2020

The crucial point this thesis is trying to answer is what concrete and practical possibilities there are nowadays in contemporary music culture teaching  in the lower classes of primary school in order to implement and use children’s folk dances accompanied by singing, as well as what the aims, tasks and procedures are in the process of conservation and fostering of this form of national tradition. A teacher as a leader of the whole teaching process should tend to provoke joy, willingness and wish in his/her pupils to learn and practice children’s folk dances accompanied by singing, which can have an important impact on establishing a positive attitude to the values of traditional culture and art.
SOFIA GUBAIDULINA’S RELATIONSHIP WITH GOD – COMPOSITIONAL, TECHNICAL AND INTERPRETATIONAL FEATURES OF HER MUSIC
Authors: Peković Nikola
Published: April 2020

The paper presents the compositions De Profundis for solo accordion, Et Exspecto for solo accordion and In Croce for accordion and cello, by one of the today’s highly appreciated composers, Sofia Gubaidulina. De Profundis is the first work by Gubaidulina for solo accordion, composed in 1978. In this work, Gubaidulina changed the ordinary sound of the accordion that she encountered in the Russian folk music, so that the sound of the accordion acquired a brand new dimension. Et Exspecto is the composition written in 1985 and has five movements. The composer expresses herself through different techniques and effects: air release valve, fast passages, tremolos, moving and static clusters, clusters by a trembling hand with a vibrato effect, etc. In Croce is a composition written in 1979 for cello and organ dedicated to the cellist Vladimir Tonkha. Gubaidulina, together with the accordion professor and artist Elsbeth Moser, rearranged In Croce for cello and accordion in 1991. The composition rests on specific crisscrossing of melodic lines, and it creates a visual impression of a cross with the listeners.

EFFECTS OF CADMIUM, AN ENVIRONMENTAL AND OCCUPATIONAL POLLUTANT, ON LIPID PEROXIDATION IN RAT PANCREATIC TISSUE
Authors: Jovanović Mirković Jasmina M. , Kocić Gordana M. , Nikolić Ružica S.
Published: April 2020

Technological development, industrialization and economic development have improved living standards, but also increased toxic metal emissions in the living and working environment. The aim of this study is the monitoring of lipid peroxidation in case of acute intoxication by heavy metal cadmium and the protective role of α-lipoic acid. In this study, we used healthy albino Wistar female rats, two or three months old. Based on the results obtained in this study, we note that cadmium-induced intoxication increases the level of malondialdehyde (MDA) in the pancreatic tissue homogenate. MDA is a direct indication of lipid peroxidation. Alpha-lipoic acid suggests reduction and correction of the toxic effect of cadmium after its exposure.

VALVE SELECTION FOR THE PURPOSE OF REDUCING THE WATER HAMMER EFFECT IN A PRESSURIZED PIPELINE
Authors: Nikodijevic Milica , Stamenković Živojin , Petrović Jelena , Kocić Miloš
Published: April 2020

This paper discusses the gravity-fed hydraulic system, which consists of the upper reservoir, the lower reservoir, the pipeline, and valves. To achieve simpler and more efficient protection of a system against water hammer, it is advisable to establish conditions in which the pressure rises as little as possible during transient regimes without using any protective equipment. The discussion focuses on the pressure rise caused by different valve types: butterfly, needle, and ball valves, as well as two valve closure intervals – 20 and 40 seconds. The systems considered have nominal diameters of DN 300 and DN 600. The problem was studied using a simulation of unsteady flow regimes of hydraulic transport. The obtained results regarding the maximum pressure rise due to water hammer were used to select the most satisfactory control valve for the considered hydraulic system.
Profundidad del Punto de Curie y Flujo Térmico en la Zona de Cuencas Offshore de Argentina
Authors: Pizarro Guillermo Domingo , Ruiz Francisco , Arecco María Alejandra , Ghidella Marta
Published: April 2020

Con el objeto de conocer la distribución de temperaturas y su relación con estructuras tectónicas se realizaron estudios frente a la costa argentina, en la zona correspondiente a la plataforma, talud y llanura abisal, en la región que va desde los 50° a 66° de longitud Oeste y 36° a 50° de latitud Sur. El análisis de Fourier de los campos potenciales permitió estimar la profundidad del punto de Curie (CPD). La variación de la profundidad del punto de Curie es un indicador de la distribución de temperaturas en la litosfera, alguna de las cuales estarían asociadas con variaciones de espesor litosférico vinculados con los fenómenos que tuvieron lugar durante la separación del continente Gondwana y apertura del Océano Atlántico Sur, como cuencas y zonas de transferencia. Se confeccionaron mapas de profundidades del punto de Curie y flujo térmico. Éstos fueron correlacionados con modelos 3D de corteza isostáticamente compensada y uno de profundidad de la discontinuidad corteza-manto superior, calculado por inversión gravimétrica. Este análisis comparativo permitió interpretar estructuras tectónicas, espesor de la corteza y grado de descompensación isostática del área de estudio. Se obtuvieron mayores profundidades al punto de Curie en la zona de corteza continental (entre 30 y 15 km, aproximadamente) que en la oceánica (entre 25 y 10 km, aproximadamente). Sobre la corteza continental los valores más someros se encontraron en los sectores correspondientes a cuencas offshore, en la corteza oceánica los valores más profundos se encontraron por debajo de la discontinuidad corteza-manto superior. Las cuencas offshore están asociadas con adelgazamiento litosférico acompañado por anomalías térmicas indicadas por elevaciones de los CPD. El basamento oceánico estaría vinculado a corrientes astenosféricas descendentes que producen un aumento de su profundidad y en la del CPD. El modelo isostático muestra un manto más profundo que el gravimétrico en sectores de cuencas offshore y menos profundo en la zona de corteza oceánica.

Published: April 2020

El análisis petrográfico automatizado integra hardware de microscopía electrónica de barrido y espectroscopía de rayos X con software experto para generar mapas de composición de rocas a escala de micras. Si bien las soluciones de petrografía automatizada, como QEMSCAN®, se usan ampliamente en las industrias de minería, procesamiento de minerales y petróleo para caracterizar los depósitos minerales y las formaciones rocosas subsuperficiales, no se ha utilizado en petrología metamórfica. Este estudio aplica el análisis petrográfico automatizado utilizando QEMSCAN® a un esquisto con granate y estaurolita de la Formación San Lorenzo, provincia geológica de Sevilla (macizo de la Sierra Nevada de Santa Marta), y demuestra que esta técnica analítica tiene una clara aplicación potencial en estudios petrológicos.
Modelado de volúmenes utilizando análisis geomorfológico para el estudio de sedimentos aportados por deslizamientos en el flanco sur del Volcán Pico de Orizaba, México
Authors: Legorreta-Paulin Gabriel , Castro Rutilio Miguel , Arana-Salinas Lilia
Published: April 2020

En la presente investigación se muestra el modelado de la relación entre el área y el volumen de deslizamientos en una cuenca de origen volcánico y sedimentario, utilizando un análisis geomorfológico de relieve para caracterizar la inestabilidad potencial de sus laderas. El uso de este método permite una mejor comprensión de la capacidad del aporte del volumen de material producido por deslizamientos, que depende de cada una de las formas del relieve y a su vez del material que lo compone. El análisis está apoyado en los Sistemas de Información Geográfica (SIG), el uso de drones y de técnicas estadísticas para crear un método integral en la estimación del volumen de deslizamientos. Este método se aplicó a la cuenca del Río Chiquito-Barranca del Muerto en el flanco sur del volcán Pico de Orizaba, México. La cuenca es propensa a los procesos gravitacionales debido a sus condiciones fisiográficas (e.g. depósitos volcánicos y sedimentarios altamente intemperizados que forman terrenos montañosos y escarpados, y que se ven afectados por precipitaciones extremas en la época de lluvias) y antropogénicas (de forestación y cambio de uso de suelo). En el área, se cartografiaron más de seiscientos deslizamientos y se agruparon en distintas formas de relieve. Utilizamos un dron para realizar mediciones a detalle de deslizamientos representativos para establecer una relación empírica entre el área del deslizamiento y su volumen. Esta relación, expresada como una ley de potencias con un exponente de escala, se usó para estimar la contribución potencial del material producido por el total de los deslizamientos en cada forma del relieve en la cuenca. El estudio muestra que el método puede ser útil en lugares remotos con difícil acceso e información topográfica escasa. También muestra que las formas del relieve sedimentarias contribuyen con más sedimentos por kilómetro cuadrado, a pesar de tener menos deslizamientos que las formas volcánicas.

Ésta transitó del siglo XIX al siglo XX de manera pacífica y sin modificaciones. En este trabajo, se cuestiona y analiza esta fórmula, y se explican las paradojas que conlleva ésta, por ejemplo porqué durante el siglo XXI se dio el efecto colateral de las sentencias y la procedencia del amparo a pesar de las múltiples reformas constitucionales en esta materia.
La realidad de la gamificación en educación primaria
Authors: Gil-Quintana Javier , Prieto Jurado Elizabeth
Published: April 2020

Se presenta un estudio cuya finalidad es descubrir la concepción que tienen profesores y alumnos sobre la gamificación y su relación con el desarrollo de procesos de aprendizaje. Se consideró una muestra intencional o de conveniencia de alumnos y profesores de cinco centros educativos de España, cuyos docentes incorporan experiencias de gamificación en sus aulas. Partiendo de un estudio multicaso basado en un método mixto se aplicaron cuestionarios y entrevistas estructuradas y semiestructuradas que permitieron recopilar datos cuantitativos y cualitativos, para después realizar el proceso de triangulación. Verificamos que los profesores y alumnos señalan múltiples ventajas de la gamificación, entre las que destaca el aumento de la participación y la interacción en el aula, la motivación hacia el aprendizaje y la diversión en las experiencias educativas. Con ello se involucran elementos didácticos, entre ellos, los contenidos y los estándares de aprendizaje asignados al correspondiente nivel curricular.
Comprensión didáctica del currículo como espacio público
Authors: Fernández Betsi
Published: April 2020

El presente estudio, referido a la dinámica curricular del siglo XXI en la Universidad Pedagógica Experimental Libertador (UPEL), en Venezuela, tiene como propósito generar criterios para la comprensión didáctica y contextual del currículo como espacio público en la institución como contribución con la gestión integral del proceso formativo de los ciudadanos, profesionales e investigadores y  la distribución del poder en la construcción del diseño curricular de la carrera docente y áreas afines con sentido social, cultural, histórico y ético. Los propósitos específicos han sido: (a) comprender el conocimiento curricular como producción intelectual condicionada por el contexto social y el momento histórico que vive la UPEL, (b) describir el proceso de legitimación del discurso curricular al concebir el currículo como espacio público, desde el debate de las ideas y los valores contextuales presentes en la UPEL. La investigación está enmarcada en el paradigma naturalista, bajo un enfoque cualitativo, en una modalidad de investigación de campo, descriptiva y documental. Se emplean como técnicas la entrevista y el análisis de contenido y como instrumentos el guion de entrevistas y la matriz de análisis de contenido. Los resultados se analizan cualitativamente, aplicando la triangulación de fuentes para generar los criterios orientadores de la comprensión didáctica y contextual del currículo como espacio público, producto de la investigación.

El fenómeno de la violencia de género en inmigrantes en Puerto Rico, al igual que los procesos de formación en investigación en este campo, ha sido poco estudiado. En este escrito exponemos las narrativas y los procesos de reflexión de un grupo de investigadoras en formación y su mentora sobre las realidades de vida de las mujeres inmigrantes sobrevivientes de violencia en la isla. Utilizando técnicas de investigación cualitativa desde el feminismo interseccional, las investigadoras en formación recopilaron reflexiones luego de trabajar desde el espacio de campo. Las narrativas expuestas parten de su análisis crítico del contexto desde donde se manifiesta la violencia contra las mujeres. Las mismas fueron codificadas utilizando el programa Atlas.ti. Entre los temas destacados se encuentran: las múltiples violencias, las historias compartidas entre participantes, trabajadoras e investigadoras y los diversos aprendizajes en temas de investigación. Además, se develan experiencias en el proceso de investigar a partir de su trabajo investigando este tema. De allí surgen recomendaciones para fortalecer la formación en investigación feminista e interseccional.
Agentes educadores y estereotipos sobre masculinidad: reflexiones para la formación de identidades masculinas alternativas.
Authors: Arias Chamorro Juan José , Navarro Verjel Kathy Alejandra , Ortega Garnica Laura Daniela
Published: April 2020

Antecedentes. Estudios preliminares relacionados con el patriarcado, la hegemonía, las masculinidades alternativas y los contextos socializadores de representaciones acerca de lo   masculino fortalecen el propósito de la revisión teórica planteada. Objetivo. Analizar la construcción de la masculinidad en relación con la socialización de los diferentes agentes educadores. Métodos. Se ha llevado a cabo una revisión sistemática de 50 documentos que abordan el tema “Masculinidad”. Resultados. Se presentan la construcción de la masculinidad de acuerdo a la existencia de modelos tradicionales o nuevos, así mismo de los espacios relacionales que socializan y reproducen el deber ser de hombres y mujeres, en esencia la familia, la escuela/colegio y la universidad. Conclusión. Se infiere que la masculinidad y su construcción se conceptualiza desde la hegemonía y la alternatividad, siendo los agentes educadores transmisores culturales de lo que debe significar la masculinidad.
Ingeniería didáctica como recurso metodológico para el aprendizaje de los conceptos de límite y continuidad
Authors: Trujillo Castro Jhoana Alexandra , Vera Gutiérrez Charen Lisset , Saraza Sosa Dilan Fabian
Published: April 2020

El entendimiento y comprensión de los conceptos matemáticos, específicamente de aquellos que se orientan en la educación media y superior, como es el caso del límite y continuidad, es considerado uno de los mayores retos educativos para los estudiantes de hoy en día, quienes tienen una concepción muy limitada acerca del concepto, tras ser vista solamente desde su representación algebraica y lenguaje abstracto. Siendo así, el siguiente artículo de investigación tiene como objetivo principal responder a esa necesidad educativa, por medio de un diseño de secuencias didácticas sobre el concepto de límite y continuidad, en el que está comprendido los cuatro tipos de representación matemática (numérico, algebraico, gráfico y comunicativo) desarrollado por Duval; el cual, a su vez, se estructuro con base en unos objetivos específicos, fundamentados en la metodología de la ingeniería didáctica. De este modo, se valoró la coherencia lógica en la comprensión del concepto, que estudiantes de Licenciatura en Matemáticas de la Universidad Francisco de Paula Santander manifestaban durante el desarrollo de las actividades, además de destacar las falencias y fortalezas en la construcción del mismo.

El propósito principal de la investigación consistió en describir las estrategias adoptadas por los docentes en la planificación, desarrollo y evaluación para la enseñanza de la matemática desde la mirada de los estudiantes. La metodología empleada es cuantitativa, de tipo descriptivo, con modalidad de trabajo de campo. Los estudiantes de la muestra se escogieron con un muestreo aleatorio simple y estuvo conformada por 51 estudiantes de un programa de formación inicial de Matemática. La recolección de la información se hizo a través de la aplicación una escala Likert. Como resultado, los docentes centran su planificación en el desarrollo de los contenidos sin considerar las necesidades de los estudiantes. Ademas se hace poco uso de las asesorías virtuales asi como la nulidad del uso de software educativo en matemáticas. Finalmente, la evaluación empleada por los docentes solo es de carácter sumativo.
