Abstract

The objective of this study was to analyse the role of resilience in the dimensions of academic burnout syndrome and psychological health in a sample of nursing students. A battery of questionnaires was administered to 218 nursing students, all of whom were in the second year of their degree at the University of Murcia (Spain). The applied protocol used the CD-RISC 10 scale for the measurement of resilience, the burnout scale MBI, and the GHQ-12 questionnaire to assess psychological health. The findings showed a significant relationship between resilience and burnout, emotional exhaustion, and self-efficacy, as well as with psychological health. Moreover, three burnout dimensions were found to be significantly linked to psychological health in the way we had predicted. Regression analysis indicated the moderating role of resilience on psychological health in emotionally exhausting situations. We conclude that the psychological characteristic resilience moderated the effect of emotional exhaustion on the psychological health of the students. The practical implications of the results are discussed in order to introduce measures for the proper training of nursing students for professional practice; we also make several suggestions for future research in this field.  相似文献

When reading in the classroom, teachers may use different methods. We examined the impact of different reading conditions on comprehension. Reading aloud involved reading the text aloud for an audience. Silent reading required the students to read the text silently. Follower reading involved listening to another student read the text aloud while having the text available for individual reading. Thirty-six fifth- and sixth-grade students read texts under the three conditions and then took comprehension tests. The students performed equally well under reading aloud and silent reading. Follower reading resulted in worse comprehension. The data suggest that the follower readers focused on their individual reading, making an effort not to listen to the student reading out loud, which consumed cognitive resources. Since reading aloud in the classroom involves not only one loud reader but also a lot of follower readers, silent reading might be the smartest choice.  相似文献

This study analyses the integration of Mapuche-Huilliche students who participate in a school sport programme based on the teaching for understanding model in a situation of social risk. In this context, 41 students (aged nine to 12) participate, 24 of whom are from the aforementioned ethnic group. To collect data, participant observation was conducted for eight months and group and individual interviews were held. The results show that the Mapuche-Huilliche students recognize themselves as members of the same collective when participating in games associated with their ethnic group. Their main motives for participating in school sport are the teaching approach and the acquisition of social capital. Cooperative learning activities are shown to foster positive interactions with non-Mapuche students.  相似文献

The aim of this paper is to address the teaching and learning processes in schools from a Vygotskian perspective based on the notion of identity artefacts (IAs) which, for our purposes, consist of documents created by the learners about themselves, in which they try to capture all the things that make sense and are meaningful to them and which, subsequently, can be used by teachers to work on curricular and pedagogical content. We conceptualise the notion of the identity artefact from the broader notions of mediation and cultural artefacts. We also provide a critical analysis of some examples of IAs.  相似文献

This article describes an action research (AR) project for designing and implementing a structured mentoring programme in a Spanish university. A student affairs unit, a team of researchers, faculty-mentors and student-protégés worked together on three cycles of AR. The result is a programmatic mentoring programme for the development of non-technical personal and professional competencies for undergraduate students. This paper describes the original situation that sparked the project, the iterative process followed, the tools and guides developed and the final programme designed. In addition to the increase in the level of satisfaction perceived by the entire university, the paper outlines the five critical factors that emerged from the AR project: the competency development process, programme value added, trust between mentors and protégés, the prominence of the student-protégé in the improvement plans and the continuous improvement culture generated.  相似文献

In relation to teaching and learning approaches that improve student learning outcomes, threshold concepts have generated substantial interest in higher education. They have been described as ‘portals’ that lead to a transformed way of understanding or thinking, enabling learners to progress, and have been enthusiastically adopted to inform teaching approaches and curriculum design. A growing body of literature has critiqued the relevance and applicability of the threshold concept theory and identified threshold concepts relevant to specific disciplines. More recent research has identified how students cross these thresholds and provided measures of the successful acquisition of threshold concepts. This literature synthesis critiques existing evidence on threshold crossing and acquisition to provide a succinct and informative overview of the outcomes to date. Key questions relevant to educators and researchers investigating whether students acquire the threshold concepts associated with their teaching, arose from the literature synthesis. These were: whether or not threshold crossing can be measured; how variation in student learning can be addressed during measurement; tools that can be used for measuring threshold crossing; whether the way units or concepts are taught should alter prior to measurement, and the challenges and limitations of measuring threshold crossing.  相似文献

The complexity of the material being taught in clinical neuroscience within the medical school curriculum requires creative pedagogies to teach medical students effectively. Many clinical teaching strategies have been developed and are well described to address these challenges. However, only a few have been evaluated to determine their impact on the performance of students studying clinical neuroscience. Interactive, 2‐hour, self‐directed small‐group interactive clinical case‐based learning sessions were conducted weekly for 4 weeks to integrate concepts learned in the corresponding didactic lectures. Students in the small groups analyzed cases of patients suffering from neurological disease that were based on eight learning objectives that allowed them to evaluate neuroanatomical data and clinical findings before presenting their case analysis to the larger group. Students’ performances on the formative quizzes and summative tests were compared to those of first‐year medical students in the previous year for whom the self‐directed, small‐group interactive clinical sessions were not available. There was a significant improvement in the summative performance of first‐year medical students with self‐directed clinical case learning in the second year (Y2) of teaching clinical neuroscience (P < 0.05) when compared with first‐year students in the first year (Y1) for whom the self‐directed learning approach was not available. Student performance in the formative assessments between Y1 and Y2 was not significantly different (P = 0.803). A target of ≥70% student scoring above 80% in the final summative examination was met. The current study revealed evidence for the impact and educational outcomes of a self‐directed, clinical teaching strategy in a clinical neuroscience curriculum for first‐year medical students.

In this paper, the problem of detrending a time series and/or estimating a wandering baseline is addressed. We propose a new methodology that adaptively minimizes different regularized cost functions by introducing an ARMA model of the underlying trend. Mixed ?1/?2-norm penalty functions are taken into consideration and novel RLS and LMS solutions are derived for the model parameters estimation. The proposed methods are applied to typical trend estimation/removal problems that can be found in the analysis of economic time series or biomedical signal acquisition. Comparisons with standard noncausal filtering techniques are also presented.  相似文献

In this paper, we analyze detection of multilevel phase-shift keying (MPSK) signals transmitted over a Gamma shadowed Nakagami-m fading channel. We derive novel analytical expression, in terms of Meijer’s G function, for Fourier coefficients of the probability density function of the received signal composite phase. Under the assumption of the imperfect reference signal extraction in the receiver, which is performed from the pilot signal, the analytical expression is derived for the symbol error probability (SEP) in the form of convergent series. The existence of the error floor is identified, and expression for its computation is provided. Mathematical proofs for convergence of Fourier series are provided for both SEP and SEP floor, and novel expressions of upper bounds for truncation errors are derived in terms of elementary mathematical functions. The convergence rate of the derived expressions is examined. Numerical results are confirmed independently by Monte-Carlo simulations.  相似文献
