A diffractive reading of dialogical feedback through the political ethics of care

With regard to improving higher education feedback practices, there is an increasing interest in using the efficacy of dialogue rather than the more traditional unidirectional approaches. We build on this impetus by considering how the ethics of care can be used to analyse the dialogical aspects of feedback. By diffractively reading insights of Boud and Molloy [2013a. “What is the Problem with Feedback?” In Feedback in Higher and Professional Education: Understanding it and Doing it Well, edited by D. Boud, and E. Molloy, 1–10. London: Routledge; Boud, D., and E. Molloy. 2013b. “Rethinking Models of Feedback for Learning: The Challenge of Design.” Assessment &; Evaluation in Higher Education 38 (6): 698–712] on dialogic feedback through the moral elements of care ethics, this paper proposes a novel way of discerning the extent to which the dialogical giving and receiving of feedback contributes to learning. To illustrate this, we draw on experiences from an Emerging Technologies professional development course for higher educators. We examine our own dialogical interactions of giving and receiving feedback using the moral elements of care ethics – attentiveness, responsibility, competence, responsiveness and trust, to provide a concrete example of how the ethics of care can be used productively for evaluating feedback practices.     

``Weighing' the Earth: a Newtonian Test and the Origin of an Anachronism

The measure G, the universal gravitational constant, is attributed to Henry Cavendish. Nevertheless, the intention of the English physicist was to measure the density of the earth, which at that time was necessary in order to decide between different theories about the composition of this planet. G was measured much later. In this article I will try to explain how Cavendish accomplished the famous experiment and what his results were. Likewise, I will consider the problems that can arise in the scientific training of students from maintaining anachronisms such as this.     

Avoiding communication barriers in the classroom: the APEINTA project

Education is a fundamental human right, however unfortunately not everybody has the same learning opportunities. For instance, if a student has hearing impairments, s/he could face communications barriers in the classroom, which could affect his/her learning process. APEINTA is a Spanish educational project that aims for inclusive education for all. This project proposes two main accessible initiatives: (1) real-time captioning and text-to-speech (TTS) services in the classroom and (2) accessible Web-learning platform out of the classroom with accessible digital resources. This paper presents the inclusive initiatives of APEINTA. Also an evaluation of the into-the-classroom initiative (real-time captioning and TTS services) is presented. This evaluation has been conducted during a regular undergraduate course at a university and during a seminar at an integration school for deaf children. Forty-five hearing students, 1 foreign student, 3 experts in captioning, usability and accessibility, and 20 students with hearing impairments evaluated these services in the classroom. Evaluation results show that these initiatives are adequate to be used in the classroom and that students are satisfied with them.     

The Effectiveness of Coursework and Onsite Coaching at Improving the Quality of Care in Infant–Toddler Settings

Research Findings: This study evaluated the effectiveness of 2 professional development interventions aimed at improving the quality of care provided by caregivers in ordinary infant–toddler child care settings, both center- and home-based. In all, 183 participants in a community college course on infant–toddler theory and practice, an in-service community model of a 48-hr course plus various levels of 1-on-1 coaching (participants were randomly assigned to 0, 5, or 15 hr), or a no-intervention comparison group were compared on their changes across 3 time points in their job-related self-efficacy, their knowledge of best practices, and the quality of their interactions with children as assessed by objective observers. Results indicated that the group with the most intensive intervention (course plus 15 hr of coaching) displayed the most consistent pattern of improvements, which met multiple analytical criteria for substantiveness. Furthermore, these findings were most apparent in the quality of interactions outcomes, and these were further still concentrated in the area of support for language and learning, the domain that showed the greatest need for improvement in infant–toddler caregivers in this sample as well as in previous research. Practice or Policy: Implications of the study results for systemic improvements to infant–toddler care are discussed, such as the importance of individual-level professional development, minimum dosage of coaching, and in-service supports to prevent declines in the quality of teacher–child interactions.     

Implementing a culturally attuned functional behavioural assessment to understand and address challenging behaviours demonstrated by students from diverse backgrounds

As the US student population continues to become increasingly diverse, educators have encountered difficulties in distinguishing between cultural differences and genuine disability indicators. This concern is clearly evident in assisting students from diverse backgrounds who demonstrate chronic challenging behaviours. Past practices (e.g. disciplinary office referrals, out-of-school suspensions, expulsion) have contributed to the likelihood of students from diverse backgrounds being misidentified as having an emotional or behavioural disorder. However, by tailoring the functional behavioural assessment (FBA), educators better differentiate cultural factors from disability characteristics and better understand the students’ needs. This paper will discuss the significance in meeting the needs of an increasingly diverse student population, provide an overview of the FBA process and present considerations in creating a culturally attuned FBA.

Body fat measurement in elite sport climbers: Comparison of skinfold thickness equations with dual energy X-ray absorptiometry

Abstract

The aim of this study was to compare equations for estimating percentage body fat from skinfold thickness in elite sport climbers by assessing their agreement with percentage body fat measured using dual-energy X-ray absorptiometry (DXA). Skinfold thickness was measured in a convenience sample of 19 elite sport climbers [9 women and 10 men; mean age 31.2 years (s = 5.0) and 28.6 years (s = 3.6), respectively]. Percentage body fat was estimated using 17 different equations, and it was also measured by DXA. A significant inter-methods difference was observed for all equations, except for Durnin's equation in men (inter-methods difference: ?0.57% and ?0.29%; 1.96 s: 5.56 and 5.23 for Siri's and Brozek's equation, respectively) and women (inter-methods difference: ?0.67% and ?1.29% for Siri's and Brozek's equation, respectively), and for Wilmore's equation using Siri's body fat equation in women (inter-methods difference: ?1.86%). In women, the limits of agreement were lower when using Durnin's equation compared with Wilmore's equation (1.96 s: 3.86% and 5.13%, respectively). In conclusion, of the 17 studied equations, Durnin's equation was the most accurate in estimating percentage body fat in both male and female elite climbers. Therefore, Durnin's equation could be used to assess percentage body fat in elite sport climbers if more accurate methods are not available. The generalizability of the results is limited by the fact that the sample was not selected at random.     

Vitamin C supplementation does not influence plasma and blood mononuclear cell IL-6 and IL-10 levels after exercise

Abstract

The aim of this study was to determine whether the highest vitamin C supplementation associated with complete bioavailability influences the plasma and blood mononuclear cell IL-6 and IL-10 response to exercise. A double-blinded study of supplementation with vitamin C was performed. After 15 days of supplementation with vitamin C (500 mg · day^?1, n = 16) or a placebo (n = 15), participants in the study completed a 15-km run competition. Blood samples were taken before and after competition. Oxidative stress markers, antioxidants, cortisol, IL-6 and IL-10 were determined in plasma or serum. IL-6 and IL-10 protein and mRNA levels were measured in blood mononuclear cells. Although higher plasma and blood mononuclear cell vitamin C levels were observed in the supplemented group when compared with the placebo one, the two groups showed identical exercise-induced changes in all the measured parameters. Exercise induced increased IL-6 and IL-10 levels in plasma and blood mononuclear cells. IL-6 and IL-10 mRNA levels in blood mononuclear cells increased after the competition. After recovery, IL-6 mRNA returned to basal levels and IL-10 mRNA levels remained elevated. In conclusion, exercise induced increased IL-6 and IL-10 production in blood mononuclear cells. However, vitamin C supplementation did not influence IL-6 and IL-10 response to exercise.     

The validity of the Devereux Early Childhood Assessment for culturally and linguistically diverse Head Start children

The Devereux Early Childhood Assessment (DECA) is a social-emotional assessment widely used by early childhood educational programs to inform early identification and intervention efforts. However, its construct validity is not well-established in independent samples of children from low-income backgrounds. We examined the construct validity of the teacher report of the DECA using a series of confirmatory factor analyses, exploratory factor analyses, and the Rasch partial credit model in a large sample of culturally and linguistically diverse Head Start children (N = 5,197). Findings provided some evidence for consistency in the factor structure of the three Protective Factors subscales (Initiative, Self-Control, and Attachment); however, the factor structure of the Behavioral Concerns subscale was not replicated in our sample and demonstrated poor fit to these data. Findings suggested that the 10 items of the published Behavioral Concerns subscale did not comprise a unidimensional construct, but rather, were better represented by two factors (externalizing and internalizing behavior). The use of the total Behavioral Concerns score as a screening tool to identify emotional and behavioral problems in diverse samples of preschool children from low-income backgrounds was not supported, especially for internalizing behavior. Implications for the consequential validity of the DECA for use as a screening tool in early childhood programs serving diverse populations of children and directions for future research are discussed.     

«Un redondel con muchas cosas dentro». Eso es un conjunto

Resumen

Se examina la comprensión infantil de algunas nociones de la teoría de conjuntos en una muestra de sesenta niños madrileños entre 6 y 11 años de edad. El análisis se centra en la definición y reconocimiento de conjuntos por parte de los niños, la formación de conjuntos a partir de un material dado y la conciencia de la utilidad de los conjuntos y su relación con otras áreas de las Matemáticas. Los resultados indican que más del 50% de los sujetos identifica el conjunto con el diagrama que lo representa y son incapaces de aplicar esas nociones a problemas concretos. Se interpretan estas dificultades a la luz de la descripción piagetiana de los dos tipos de abstracción—empírica y reflexiva—, y los dos tipos de conocimiento—físico y lógico-matemático—a que dan lugar.
