Since the idea of method variance was inspired by D. T. Campbell and Fiske in 1959, many papers have demonstrated an ongoing debate about both its nature and impact. Often, method variance entails an upward bias in correlations among observed variables—common method bias. This article reports a split-ballot multitrait–multimethod experimental design for estimating 2 opposite biases: the upward biasing method variance from the reaction to the length of the response scale and the position of the survey items in the questionnaire and the downward biasing effect of poor data quality. The data are derived from self-reported behavior related to emotional and social competencies. This article illustrates a methodology to estimate common method bias and its components: common method scale variance, common method occasion variance, and the attenuation effect due to measurement errors. The results show that common method variance has a much smaller impact than random and systematic measurement errors. The results also corroborate previous findings: the greater reliability of longer scales and the lower reliability of items placed toward the end of the survey. 相似文献

Se presenta aquí un caso de aplicación del «análisis del discurso» para la evaluación, los intercambios lingüísticos de profesores y alumnos en clase y, de este modo, de la calidad didáctica de las clases de lengua. El modelo se propone como técnica para la autoevaluación y optimización de las estrategias de instrucción… 相似文献

AbstractThis article describes the teaching experience gained from the introduction of the Spanish electronic European Language Portfolio (eELP+14) in the university teaching of the Erasmus Intensive Language Course (EILC) within the Vives Network of Universities. The aim was to seek the views of teachers during their first experimental work with undergraduates in relation to their learning of Catalan culture and language. A pilot study was carried out following a mixed methods methodology, with a QUAN+qual design, through two online ad hoc questionnaires (pretest-posttest). Overall, the tool has been assessed positively with regard to pedagogical aspects (reflection and self-evaluation of the Biography) and communication aspects (the linguistic profile of the Passport), although some difficulties have been highlighted concerning the time students need to dedicate to it and the amount of time they actually have, as well as the need to introduce technological and linguistic improvements. On the one hand, the eELP is recognized as an educational innovation which is entirely suitable for the current university context, and on the other hand, it is considered to have only a moderate influence in the learning of languages and cultures. 相似文献

¿Qué ocurre cuando un niño comprende o no comprende? ¿Cómo se explica psicológicamente el proceso de comprensión de un texto? Después de aportar una base a ese nivel, el autor construye sobre ella en este artículo un programa de instrucción para mejorar las habilidades de comprensión y un método de evaluación de esas habilidades. 相似文献

AbstractIn the context of a changing society, strategies are required to eradicate the phenomenon of antisocial behaviour. The Aprender a Convivir universal prevention programme tries to provide such a response. This study attempts to test the effectiveness of the programme through a quasi-experimental long-term study carried out over three years in some nursery schools. Of the students who participated in this study (N = 784), those from the experimental group showed significant increases in social competence compared to the control group, and behavioural problems decreased, albeit not in any significant way. To draw conclusions about the effectiveness of the programme, further improvements are proposed to the design of the study. 相似文献

AbstractThe introduction of the European Higher Education Area means that undergraduate dissertations (UD) are now compulsory, which represents an important change for the Spanish university system due to the important consequences this will have on academic functioning. This study provides key information on the processes of supervising and assessing UDs, from the perspective of students, as well as consequent proposals to improve them. The results obtained indicate that initiatives need to be put in place, at least in the participating institutions where the study has been developed, focused on the improvement of the time periods, means and resources needed to develop the UD, the introduction of more adequate criteria than those currently used for assessment, better training for the tutors involved, more appropriate and precise prior information for students in relation to the UD, and more preparation for students to enable them to carry out the UD. 相似文献

AbstractThis paper presents a study of service learning (SL) as a methodology to facilitate the development of media competence in future teachers. The SL methodology fulfils a training and service need for two different populations: in our case, a preschool/primary school and students from the Bachelor’s in Education degrees at the Universidad de Jaén. The study involved 193 university students who carried out 63 projects involving new technologies. The goal of these projects was to produce materials to be used on smartboards, advertising materials, picture-reading materials or multimedia resources, among others. These materials were designed and created in the university classes as a part of the practical sessions of a course and were then given away to be used at a preschool/primary school. At the end of the project, the university students filled out a questionnaire that required them to compare SL to traditional activities in terms of how well each type of practice helps them to achieve the 20 competences of the course. The results show that students recognize the value of the SL methodology more than traditional practice, which suggests the relevance of this methodology for university students. 相似文献

Two experiments tested the effects of food deprivation on discounting in pigeons. An adjusting-amount procedure was used to estimate the subjective value of food at delays ranging from 1 to 24 s. Experiment 1 compared pigeons’ discounting of delayed food reinforcers at 75 %–80 % and 90 %–95 % of free-feeding weight. Experiment 2 compared discounting under 1- and 23-h food deprivation. In both experiments at both deprivation levels, discounting was well described by the hyperboloid discounting function. No systematic effect of level of deprivation on degree of discounting was observed in either experiment. This finding is consistent with the view that pigeons’ choices are controlled by the relative, rather than the absolute, value of reinforcers. 相似文献

Scientific publishing in mathematics and physics (as in other exact sciences) is rapidly changing, and it is important to identify and predict relevant changes and their potential consequences. To understand such changes, the authors begin with a brief history of scientific publishing and the rise of digital publishing. The study presents a qualitative comparison of the basic features of traditional and digital forms of publications (books, journals, libraries and databases, archives, webinars, forums, digital learning materials), on the basis of which relevant changes (specific for mathematics and physics) are identified and predicted. Several tables describing the most popular and useful scientific online tools for scientists, professors, students, and engineers are listed. 相似文献
