Unpacking the Impacts of a Universal Parenting Program on Child Behavior     

Elisa Rachel P. Altafim  Dana C. McCoy  Maria Beatriz M. Linhares 《Child development》2021,92(2):626-637

This study examined the theory of change of the ACT Raising Safe Kids parenting program, including whether intervention effects on children's behavior problems were explained by improvements in mothers’ reported parenting practices, as well as whether baseline child behavior problems moderated these relations. Adult mothers of 3-to 8-year-old Brazilian children were assigned to the intervention (n = 97) or control (n = 46) groups. Results showed that the intervention improved mothers' perceptions of their parenting practices (positive discipline, emotional and behavioral regulation, and communication). Intervention-induced reductions in children’s internalizing and externalizing behavior problems were mediated by improvements in mothers’ emotional and behavioral regulation. Program effects were strongest for children with high levels of baseline behavior problems.  相似文献   

Visual Literacy in Primary Science: Exploring Anatomy Cross-Section Production Skills     

Beatriz García Fernández  José Reyes Ruiz-Gallardo 《Journal of Science Education and Technology》2017,26(2):161-174

Are children competent producing anatomy cross-sections? To answer this question, we carried out a case study research aimed at testing graphic production skills in anatomy of nutrition. The graphics produced by 118 children in the final year of primary education were analysed. The children had to draw a diagram of a human cross section, integrating knowledge of anatomy acquired from longitudinal sections. The results show that they have very limited skills in producing these graphics judging by the dimensions (scale, shape, organs represented and its organization inside the section) and their conception of human anatomy at thoracic level (location of the organs, elements in the spaces between them and connections between organs). The results also indicate that the only exposure to cross-sections in daily life is not enough by itself to draw them correctly, so this type of graphic production should be addressed from the earliest stages of education, since it contributes to the development of visual literacy, and this is a crucial skill when it comes to learning science concepts and developing scientific literacy.  相似文献   

Should I use co-assessment in higher education? Pros and cons from teachers and students’ perspectives     

Victoria Quesada  Miguel Ángel Gómez Ruiz  Maria Beatriz Gallego Noche  Jaione Cubero-Ibáñez 《Assessment & Evaluation in Higher Education》2019,44(7):987-1002

Co-assessment is a type of participatory assessment in which the teacher and student jointly discuss, negotiate and assess the student’s task or performance. Although the literature on co-assessment is scarce, some authors highlight the benefits for students of participating in co-assessment in higher education, including learning, improved communication, and greater assessment literacy. This study has a double objective: on the one hand, to analyse the strengths and limitations perceived by students participating in co-assessment practices; on the other hand, to explore the strengths, weaknesses, opportunities and threats perceived by professors participating in the experience. The study was developed in 8 class groups with the participation of 470 students and 4 teachers. The qualitative analysis of the data obtained from the questionnaires and focus groups indicates that the students acknowledged several strengths, among which learning from mistakes was prominent. Students also noted some limitations, particularly the lack of adjusted scoring. Professors offered another perspective that complemented the vision of their students, noting that co-assessment presents opportunities as well as risks that may jeopardise its implementation.  相似文献   

Emotion,understanding, and social skills among boys at risk of attention deficit hyperactivity disorder     

Inna Kats‐Gold  Beatriz Priel 《Psychology in the schools》2009,46(7):658-678

There is growing interest in the role of emotional competence in middle school children's adjustment and functioning, yet many populations remain underresearched. Few studies have explored the emotional competence, especially emotion understanding, of children with, or at risk of, attention deficit hyperactivity disorder (ADHD), and even fewer have examined the role emotion understanding plays in these children's social skills. Our study investigates a profile of the emotion understanding capacities of Israeli boys at risk of ADHD and evaluates its association with their social skills. One hundred and fifty‐two boys (grades 4–6) were each assigned to an at‐risk (n = 66) or comparison (n = 86) group based on their scores on an ADHD symptoms questionnaire (Conners Rating System–Revised). The two groups were matched on age, socioeconomic status and class, and school environment. Group comparisons revealed that relative to their non–at‐risk counterparts, at‐risk boys demonstrated less mature emotion understanding. Finally, our findings indicate that poor emotion understanding plays a more notable role in the social functioning of at‐risk than non–at‐risk children. This study's contribution to the understanding and school treatment of children with ADHD emotional and social competencies is discussed. © 2009 Wiley Periodicals, Inc.  相似文献   

University surroundings and infrastructures that are accessible and inclusive for all: listening to students with disabilities     

Anabel Moriña  Beatriz Morgado 《Journal of Further & Higher Education》2018,42(1):13-23

The main topic of this article is architectural barriers and infrastructures as identified by university students with disabilities. The data presented is part of a much wider research project, sponsored by Spain’s Ministry of Economy and Competition. A biographical-narrative methodology was used for this study. The results presented have been classified based on one of five barrier types: urban (barriers that are outside the actual university campus), transport (public transportation and personal vehicles), building (obstacles inside university buildings), environmental (those elements within the classroom, including furniture, excessive noise or inadequate temperatures) and communication (these are divided into signposting and barriers when accessing information). Lastly, a variety of questions are considered in the conclusions which indicate that universities still need a certain degree of adaptation and readjustment to really be accessible and inclusive, in keeping with the principles of universal design.  相似文献

Acute intraocular pressure changes during isometric exercise and recovery: The influence of exercise type and intensity,and participant´s sex     

Jesús Vera  Beatriz García-Durán  Alejandro Pérez-Castilla  Beatriz Redondo  Gabriel Delgado 《Journal of sports sciences》2013,31(19):2213-2219

ABSTRACT

We assessed the intraocular pressure (IOP) behaviour during a 1-minute period of isometric physical effort and the immediate 1-minute of recovery in the mid-thigh clean pull and squat exercises at three different intensities. Twenty physically active individuals performed the isometric mid-thigh clean pull and squat exercises at three intensities (0% [low-intensity], 25% [medium-intensity] and 50% [high-intensity] of the maximum isometric force). IOP was semi-continuously measured by rebound tonometry. There was a statistically significant effect of exercise intensity on IOP (p < 0.001, ?_p² = 0.416), observing that IOP increments were positively associated with exercise intensity. The mid-thigh clean pull and squat exercises did not demonstrate differences (p = 0.510), and also, no differences were observed between men and women (p = 0.683). The IOP changes during the isometric physical effort showed a positive linear behaviour in all conditions (r = 0.70 to 0.96). IOP returned to baseline levels after 8 seconds of recovery. Our data showed a progressive and instantaneous IOP increment during isometric exercise, which was positively associated with exercise intensity. IOP changes were independent on the type of exercise and participant´s sex. After exercise, IOP rapidly (≈ 8 seconds) returned to baseline levels.  相似文献   

Is passive drag dependent on the interaction of kayak design and paddler weight in flat-water kayaking?

Abstract

Drag is one of the major factors that influences kayaking performance. To focus on the drag of the kayak’s hull shape and the paddlers’ weight per se, the passive drag (D_p) was measured on a flat-water sprint course for one paddler with added weights. D_p was measured by an electromechanical towing device using a load cell, at incremental and constant velocities from 2.78 to 5.56 m/s. Three kayaks of different sizes and shapes (Nelo® K1 Quattro-M, ML, and L) were used and the paddlers’ body weight was adjusted with weights so the total paddler weight in the kayak was 65, 75, and 85 kg. The mean D_p increased by the power function of D = kvⁿ (mean R² = .990; SD .006). The D_p went from 21.37?±?1.29 N at 2.78 m/s to 89.32?±?6.43 N at 5.56 m/s. For the two lighter weighted kayaks (65 and 75 kg), the lowest D_p was observed with different kayak sizes (M, ML, or L) depending on the target velocity. The manufacturers suggest that paddlers should select a kayak size according to their body weight to minimise drag; however, the results of this study suggest that target velocities, and thus competition distance should also be factored into kayak selection.  相似文献   

Children’s Models about Colours in Nahuatl-Speaking Communities     

Leticia Gallegos-Cázares  Fernando Flores-Camacho  Elena Calderón-Canales  Elvia Perrusquía-Máximo  Beatriz García-Rivera 《Research in Science Education》2014,44(5):699-725

This paper presents the development and structure of indigenous children’s ideas about mixing colours as well as their ideas about each colour, derived from their traditions. The children were interviewed both at school and outside it, and an educational proposal was implemented. Ideas expressed in the school context were analysed using the partial possible model, which states that the inferences and explanations used to describe a subject consist of constricting ideas, rules of correspondence, and a set of phenomenological inferences about processes. After identifying these components in the children’s ideas, we developed models to describe their conceptions about mixing colours. We employed a different approach to analyse children’s ideas related to their cultural context. The results showed that children change from a conception that focuses on colours as entities that do not change and as properties of objects (model 1) to the idea that colour represents a quality of substances or objects that can be modified by mixing colours (model 2). Cultural context analysis showed that stories are independent from one another and that they are not connected to colour mixing processes, only to the actions of colour on people. We concluded that students generate independent constructions between school and cultural knowledge.  相似文献   

Historians, archivists, and social activism: benefits and costs   总被引：1，自引：1，他引：0  

Sonia Yaco  Beatriz Betancourt Hardy 《Archival Science》2013,13(2-3):253-272

This article explores how activism by historians and archivists relates to and affects their work and how their work affects their activism. The findings are based on a survey of 195 historians (including educators) and archivists who self-identified as “someone who takes part in activities that are intended to achieve social or political change, especially someone who is a member of an organization.” The respondents participate in a wide variety of causes. Typically, their activities as activists reflect their professional skills and concerns, with a large majority involved in collecting and preserving the records of activist organizations. The article examines the benefits and costs for employers of employee activism, concluding the benefits outweigh the costs. The article also examines how activism affects the relationship between employers and their activist employees. While many activists receive recognition and other benefits from their employers for their activism, a minority suffers negative consequences up to and including firing and a substantial number feel inhibited from activism by their employers. The article also explores the effects of activism for the different occupational groups, determining that they are relatively similar but with some differences.  相似文献
