Estrés laboral y su relación con los turnos y áreas de trabajo en el personal que labora en campos de perforación de una empresa del sector hidrocarburos en Colombia

El personal que labora en áreas de campo en las empresas de hidrocarburos se enfrenta de manera sistemática a diferentes exposiciones ocupacionales que pueden estar relacionadas con el estrés laboral o tener algún tipo de incidencia en este sentido. Objetivo: establecer la prevalencia de síntomas de estrés percibidos por un grupo de trabajadores que laboran en cuatro campos de perforación de hidrocarburos e identificar su relación con el turno y área de trabajo (administración y producción) en que desempeñan su labor. Metodología: Estudio de corte transversal, en una empresa del sector hidrocarburos que opera en el municipio de Puerto Boyacá, con una muestra de 115 trabajadores, la información se recolectó a través de la aplicación del cuestionario para la evaluación del estrés – Tercera versión del Ministerio de Salud y Protección Social de la República de Colombia y la Pontificia Universidad Javeriana de Bogotá. Resultados: El género de mayor frecuencia fue el masculino con el 86%, el 39% de los trabajadores se encuentra en el grupo etario entre los 47-57 años refirió un nivel de estrés alto. Se observó que la línea operativa y profesional y los analistas, fueron los que reportaron un nivel de estrés alto. Conclusiones: El trabajo que desarrolla el personal que labora por turnos en campos de perforación, es un generador de estrés por lo que debe ser monitoreado de forma periódica, haciendo énfasis en la promoción de estilos laborales saludables y la prevención de diagnósticos que afecten el componente conductual.

Interacciones de género estudiante-profesor, deserción y rendimiento académico en Colombia

En este trabajo se estima el efecto del género del profesor sobre la deserción y el rendimiento educativo de los estudiantes en Colombia durante el periodo 2009-2012. La estrategia empírica se fundamenta en un modelo de regresión lineal que establece la relación entre la proporción de profesoras interactuada con el género del estudiante. Los resultados sugieren que existe un sesgo de selección debido a que las profesoras aumentan la probabilidad de que las niñas finalicen la educación media, lo que implica que la composición de habilidades entre hombres y mujeres no es la misma. Luego de corregir este sesgo de selección, se encuentra un resultado significativo en el género del profesor. Un aumento de una desviación estándar en la proporción de profesoras incrementa en 0.01 desviaciones estándar el puntaje de los niños en la prueba de matemáticas y el puntaje de las niñas en la prueba de lenguaje. Este trabajo utiliza información proveniente de la prueba Saber 11, la Resolución 166 y el concurso docente.

Las secuencias didácticas de lengua: una encrucijada entre teoría y metodología

[ES] El objetivo de este trabajo es analizar secuencias didácticas(SD) para enseñar lengua/s diseñadas por profesores de educación primaria y proponer algunos indicadores que guíen a los enseñantes en la confección y validación (o autoevaluación) de las mismas. Entendemos la secuencia didáctica en el sentido de sus creadores ginebrinos, es decir, como una herramienta para la enseñanza del género textual como unidad comunicativa. El diseño de las secuencias estudiadas en este artículo se realiza a lo largo de unas sesiones de formación de profesorado; a la vista de los obstáculos que se observan en su elaboración (dificultades para explicitar la consigna, noción difusa del género textual, etc.), decidimos analizarlas a partir de unos ítems o criterios extraídos básicamente de los principios que rigen las secuencias didácticas. Pensamos que las principales dificultades derivarán de las concepciones teóricas y metodológicas previas que tienen los profesores y de una concepción disociada de la SD y del género textual. Los resultados ponen de relieve cuáles son algunos de los aspectos que merecen especial atención a la hora de diseñar secuencias didácticas y sugieren el interés de contar con unos indicadores que guíen al docente en la confección de las mismas. Eso no significa, sin embargo, que deba tratarse de una lista cerrada y, evidentemente, futuros trabajos habrán de modificarla y completarla. Hasta el momento, estos criterios nos permiten confirmar la importancia de insistir en las bases teóricas y metodológicas de las secuencias didácticas en el marco de las sesiones formativas.

The MaPS project: mapping teacher conceptions of musical development

The chapter starts from the premise that an historically- and institutionally-formed orientation to music education at primary level in European countries privileges a nineteenth century Western European music aesthetic, with its focus on formal characteristics such as melody and rhythm. While there is a move towards a multi-faceted understanding of musical ability, a discrete intelligence and willingness to accept musical styles or 'open-earedness', there remains a paucity of documented evidence of this in research at primary school level. To date there has been no study undertaken which has the potential to provide policy makers and practitioners with insights into the degree of homogeneity or universality in conceptions of musical ability within this educational sector. Against this background, a study was set up to explore the following research questions: 1. What conceptions of musical ability do primary teachers hold a) of themselves and; b) of their pupils? 2. To what extent are these conceptions informed by Western classical practices? A mixed methods approach was used which included survey questionnaire and semi-structured interview. Questionnaires have been sent to all classroom teachers in a random sample of primary schools in the South East of England. This was followed up with a series of semi-structured interviews with a sub-sample of respondents. The main ideas are concerned with the attitudes, beliefs and working theories held by teachers in contemporary primary school settings. By mapping the extent to which a knowledge base for teaching can be resistant to change in schools, we can problematise primary schools as sites for diversity and migration of cultural ideas. Alongside this, we can use the findings from the study undertaken in an English context as a starting point for further investigation into conceptions of music, musical ability and assessment held by practitioners in a variety of primary school contexts elsewhere in Europe; our emphasis here will be on the development of shared understanding in terms of policies and practices in music education. Within this broader framework, our study can have a significant impact internationally, with potential to inform future policy making, curriculum planning and practice.

Undersökande arbetssätt i NO-undervisningen i grundskolans tidigare årskurser

This thesis deals with the use of inquiry-based approaches in primary school science. The aim is to investigate the goals and purposes that are constituted by the curriculum and by the teachers in interviews and through their teaching in the classroom. The results are used to develop conceptual tools that can be used by teachers’ in their work to support students’ learning of science when using an inquiry-based approach. The thesis is comprised of four papers. In paper one a comparative analysis is made of five Swedish national curricula for compulsory school regarding what students should learn about scientific inquiry. In paper two 20 teachers were interviewed about their own teaching using inquiry. Classroom interactions were filmed and analyzed in papers three and four, which examine how primary teachers use the various activities and purposes of the inquiry classroom to support learning progressions in science. The results of paper one show how the emphasis within and between the two goals of learning to carry out investigations and learning about the nature of science shifted and changed over time in the different curricula. Paper two describes the selective traditions and qualities that were emphasized in the teachers’ accounts of their own teaching. The results of papers three and four show how students need to be involved in the proximate and ultimate purposes of the teaching activities for progression to happen. The ultimate purposes are the scientific purposes for the lesson (as given by the teacher or by the curriculum), whereas the proximate purposes are the more student-centered purposes that through different activities should allow the students to relate their own experiences and language to the ultimate purpose. The results show the importance of proximate purposes working as ends-in-viewin the sense of John Dewey, meaning that the students see the goal of the activity and that they are able to relate to their experiences and familiar language.

Indicativos de problemas de comportamento e de habilidades sociais em crianças: um estudo longitudinal

O estudo teve como objetivo avaliar o desenvolvimento de crianças indicadas por suas professoras na Educação Infantil (EI) como apresentando problemas de comportamento (Grupo IPC) ou comportamentos socialmente habilidosos (Grupo ICSH), em dois momentos: quando tinham cinco anos e quando tinham 10 anos. Participaram 48 professoras de 62 crianças de ambos os sexos. Os instrumentos utilizados foram Questionário de Respostas Socialmente Habilidosas para Professores e Escala Comportamental Infantil B. Os resultados indicaram diminuição dos problemas de comportamento e aumento dos comportamentos socialmente adequados no grupo IPC; os grupos eram bastante diferentes na primeira avaliação, quando na EI, mas as mudanças se atenuaram no ensino fundamental. em ambas as avaliações, as crianças do Grupo ICSH foram avaliadas como mais habilidosas.

Parceria intergeracional e formação docente

O artigo focaliza o potencial formativo da parceria intergeracional na formação docente -inicial e continuada -, tendo por pressuposto a existência de uma cultura profissional específica do magistério (JULIA, 2001), o papel dos professores como produtores de saberes sobre o ensino (SHULMAN, 1986; TARDIF; LESSARD; LAHAYE, 1991), bem como a importância da escola como eixo para a formação docente (NÓVOA, 1999; AZANHA, 2000). São apresentados dados sobre um trabalho formativo que, desde 2006, vem sendo desenvolvido na cidade de Rio Claro, reunindo estudantes do curso de Pedagogia da UNESP e professores dos anos iniciais do ensino fundamental. de acordo com a proposta, futuros professores e professores em exercício atuam como parceiros, em uma relação de colaboração nas atividades docentes. Além da formação profissional dos sujeitos envolvidos, o investimento nessas parcerias tem em vista o desenvolvimento de uma dimensão mais colaborativa no seio da cultura do magistério.

Electromyographic analysis of masseter and anterior temporalis muscle in sleep bruxers after occlusal splint wearing

Bruxism is widely defined as an anxiety response to environmental stress. Occlusal splints are frequently used in sleep bruxism, to protect teeth from damage resulting from the contraction force of mandibular muscles, or to reduce the orofacial pain by relaxing masticatory muscles. Surface electromyography (EMG) of the right and left masseter and temporalis muscles was performed in 15 women presenting sleep bruxism and temporomandibular disorders related to occupational stress, after nocturnal use of the occlusal splint. The EMG signals were recorded twice per patient: After a work shift (pre-splint) and after a night of sleep with the occlusal splint (post-splint) before a new workday. The parametric t-paired test was used to compare differences of the RMS amplitude between pre and post-splint records, for resting and maximal clenching effort. The level of significance for each comparison was set to p < 0.05. The results of the study supports the premise that the use of occlusal splint reduces EMG activity in the masseter and anterior temporalis muscles, in patients who presented with sleep bruxism related to occupational stress. © 2011 Elsevier Ltd.

Efeito de um programa de ginástica laboral na saúde, estados de ânimo e estresse diário do trabalhador

The practice of regular physical activity has been widely recommended in the literature, indicating an improvement of the physical and psychological activities promoted through the routine of workers. In this sense, physical activity has become of great importance in the workplace, for the prevention of injuries caused by normalizing bodily functions and staff providing relaxation and socialization, basic elements of daily life a worker. This study aimed to analyze the effects of a active break program in the routine of workers in their mood and stress, even checking the influence of physical activity on quality of life of participants. We selected 15 individuals of both genders, the restaurant staff University, UNESP - Rio Claro-SP. The activities lasted four months, two times a week, at the beginning of the workday, for 15 minutes, followed by stretching and playful activity. The evaluations were answered a week before the execution of the program and lists of mood states have been answered before and after the activity, and the end of working hours and also at the beginning and end of the days when there were no interventions. After analyzing the results, we concluded that the participants have a good index of perception of quality of life with total score of 76.6 for mental and physical health and that all assets are considered in accordance with the recommendations of 150 minutes of physical activity per week. More than 50% of them have symptoms of stress found mostly in the resistance stage, and no changes were found in the mood states when practicing active break or not. We conclude that the changing of moods can be associated with the fact that workers are already active, another reason may be due to low number of participants in the study, given other studies show that there is a change and that active break interferes positively in mood states of individuals
