This study provides a first-time analysis of the differences in the time dedicated each day to different sedentary activities (SA) (productive, technology-based recreation and social activities) and their relation with the academic performance of Spanish adolescents according to sex, school year and socioeconomic status (SES). The sample was made up of 681 participants (50.2% girls), between 12 and 18 years old, who completed self-reported questionnaires. The likelihood of obtaining lower levels of academic success increase in adolescents who spend two or more hours on social SAs and have a lower SES. With boys, this increases further if they spend four or more hours on SAs involving technology-based recreation and two or less hours on productive SAs. In conclusion, adolescents spend a high number of hours carrying out sedentary activities after school. This is something that needs controlling since it may have a detrimental effect on their academic success, especially among adolescent boys.  相似文献   

A theoretical application of epistemological oppression to the psychological assessment of special educational needs; concerns and practical implications for anti-oppressive practice     

Alexandra Sewell 《Educational Psychology in Practice》2016,32(1):1-12

There has been brief but important discussion regarding the concepts of “oppression” and “anti-oppression” in the educational psychology professional practice literature. This article aims to both further and focus this discussion. In particular, the concept of “epistemological oppression” is introduced and the significance it has for the meaning-making and knowledge construction activities of educational psychology practice is explored. A conceptual application of two predominant theories of epistemological oppression, Standpoint Theory and the Three Levels of Epistemological Oppression theory, is made with regard to the psychological assessment of special educational needs (SEN). It is posited that as psychological assessment of SEN is fundamentally an epistemological endeavour these two theories provide a crucial framework through which educational psychologist (EPs) may base reflective practice in order to realise and ameliorate potential oppression. It is concluded that EPs have a responsibility to orient themselves toward the potential for epistemological oppression in their work and help towards its amelioration.  相似文献   

Adaptation in the transition to school: perspectives of parents,preschool and primary school teachers     

Karla Correia  Alexandra Marques-Pinto 《Educational research; a review for teachers and all concerned with progress in education》2016,58(3):247-264

Background: Transition to school is a highly demanding phase at an intellectual, social and emotional level and is, therefore, an opportunity for growth and development. Despite the greater emphasis given to school transition in Portugal over recent years, namely by means of new educational policies, studies on the adaptation processes involved in the transition to primary school are still scarce.

Purpose: The present qualitative study sets out to contribute to the knowledge on the adaptation process of children to school transition (around age 6) in Portugal, by comparing preschool teachers’, primary school teachers’, and parents’ perceptions about success indicators and relevant factors in the transition to school.

Design and method: In order to collect data, 14 focus group interviews with different participants were conducted, three with preschool teachers (N = 18), three with primary school teachers (N = 13), four with parents conducted before the child’s transition to primary school (N = 14) and four with parents conducted after the child’s transition to primary school (N = 20).

Results: While the preschool and primary school teachers stressed factors of a family nature, such as parental involvement and parental support of children, the parents referred more frequently to the overall running of the school and the characteristics and methodology of the teacher as being relevant to the adaptation process in the first year of primary education.

Conclusions: The findings suggest different factors associated with adaptation to school and also offer clues for designing strategies to facilitate such adaptation. New strategies are needed to facilitate the construction of a robust educational family–school partnership.  相似文献   

Differential Treatment of Siblings: Interview and Diary Analyses Comparing Two Family Contexts   总被引：4，自引：0，他引：4  

Alexandra L. Quittner  Lisa C. Opipari 《Child development》1994,65(3):800-814

We assessed parental differential treatment of siblings (maternal time, affection, discipline) in normal and high-risk families. Differential treatment was measured using home interviews, nightly phone ratings, and daily diaries tracking how mothers spent their time. Subjects were 40 mothers of toddlers (average age 2 years) and preschoolers (average age 4 1/2 years): half were caring for a younger child with a chronic illness (i.e., cystic fibrosis), and half were caring for two healthy children. Little evidence of parental differential treatment was found in the home or phone interview data. However, on the diary variables, both quantitative and qualitative differences in parental treatment were found in cystic fibrosis (CF) versus comparison families. Specifically, mothers spent more individual time with younger, chronically ill children in play and mealtime activities than with their older, healthy siblings. Further, mothers in the CF group rated time spent with older children as significantly more negative than time spent with younger children. Convergence between measures of differential treatment and advantages of using a high-risk comparison approach are discussed.  相似文献   

Differences in African‐American and European‐American students' engagement with nanotechnology experiences: Perceptual position or assessment artifact?     

Thomas Tretter  Manuela Paechter  Dennis Kubasko  Alexandra Bokinsky  Thomas Andre  Atsuko Negishi 《科学教学研究杂志》2007,44(6):787-799

This study examined middle and high school students' perceptions of a weeklong science experience with nanotechnology and atomic force microscopy. Through an examination of student self assessments and their writing, the study allowed us to examine some of the issues that may contribute to discrepancies that are seen between European‐American and African‐American students in science. The results of the study showed that after instruction, African‐American students were significantly more likely to agree with the statement that “science involves mostly memorizing things and getting the right answer,” than European‐American students. In addition, European‐American students were significantly more likely to write their newspaper stories from a first person perspective than their African‐American peers. The results are discussed in light of the assessment task, students' interpretations of formal writing, cultural differences in the use of language in writing, and possible cultural differences in students' perceptions of the science experience. © 2007 Wiley Periodicals, Inc.

Game Over? No Main or Subgroup Effects of the Good Behavior Game in a Randomized Trial in English Primary Schools     

Emma Ashworth  Neil Humphrey  Alexandra Hennessey 《Journal of research on educational effectiveness》2020,13(2):298-321

Abstract

This study aimed to examine the impact of a universal, school-based intervention, the Good Behavior Game (GBG), on children’s behavior, and to explore any subgroup moderator effects among children at varying levels of cumulative risk (CR) exposure. A 2-year cluster-randomized controlled trial was conducted comprising 77 primary schools in England. Teachers in intervention schools delivered the GBG, whereas their counterparts in control schools continued their usual provision. Behavior (specifically disruptive behavior, concentration problems, and pro-social behavior) was assessed via the checklist version of the Teacher Observation of Classroom Adaptation. A CR index was calculated by summing the number of risk factors to which each child was exposed. Multilevel models indicated that no main or subgroup effects were evident. These findings were largely insensitive to the modeling of CR although a small intervention effect on disruptive behavior was found when the curvilinear trend was used. Further sensitivity analyses revealed no apparent influence of the level of program differentiation. In sum, our findings indicate that the GBG does not improve behavior when implemented in this sample of English schools.  相似文献   

The relationship between resistance to change and Romanian teachers’ attitude towards continuing education: the moderating role of conscientiousness     

Ramona Paloş  Simona Alexandra Gunaru 《师资教育杂志》2017,43(4):458-473

Previous research highlights that personal factors are more important than contextual factors in explaining teachers’ behaviours in relation to learning participation. The present study explores the relationship between two personal factors (dispositional resistance to change and teachers’ attitude towards continuing education) and the moderating role of conscientiousness on this relationship. The data have been gathered from 142 teachers from the field of special and public education, using three questionnaires: Revised Adult Attitudes Towards Continuing Education Scale, Resistance to Change Scale and IPIP-50. The main results show that, firstly, conscientiousness has a moderating role on the relationship between dispositional resistance to change and enjoyment of learning, and secondly, teachers in special education consider their continuing education as being more important than teachers in the regular system. Knowing this, we can predict and increase teachers’ participation in continuing education and can improve training design.  相似文献   

Engaged food science: Connecting K‐8 learners to food science while engaging graduate students in science communication     

Alexandra J. Macbeth  Hannah S. Zurier  Erin Atkins  Sam R. Nugen  Julie M. Goddard 《Journal of Food Science Education》2021,20(1):31-47

Connecting the public to concepts in science, technology, engineering, and mathematics (STEM) is an essential for technological advancement and inspiring future scientists, impacting both the communicator and the audience's understanding of scientific topics. Without proper communication of scientific knowledge, acceptance and implementation of new technologies can be hindered. Additionally, increasing public awareness about current scientific issues through STEM engagement permits more informed policy and consumer choices, especially in the field of food science where many new food technologies are met with initial resistance by the consuming public. Here, we describe an event that introduced topics in food science to the nonexpert public, including K‐8th grade participants and their adult caregivers in an informal learning environment. This program consists of six activities that collectively introduce three areas in food science: food chemistry, food microbiology, and process engineering. Protocols are provided for each activity including a materials list (with the option to scale up or down according to event duration, event space allowances, and number of participants), learning objectives and discussion points that are adaptable to different age groups, event spaces, or budgets. Each activity has a participatory component to ensure both audience member and instructor engagement. A program designed for food science communication empowers young scientific minds to better understand complex scientific topics and could inspire them to envision a possible career in STEM fields, with the additional benefit of providing graduate students an exciting medium through which they may practice their science communication skills, potentially benefiting not only their personal academic and professional skills but also broader societal needs.  相似文献   

Organizational Capacity Building for Sexual Health Promotion     

Lisa G. Colarossi  Randa Dean  Kavitha Balakumar  Alexandra Stevens 《American journal of sexuality education》2017,12(1):1-19

We present an organizational capacity building program that is a systemic approach to training professionals, creating organizational policies and practices, and enhancing the physical environment with materials about sexual and reproductive health. The evaluation of four different organizations showed increases over six months in: staff reports of administrative support for providing materials and referrals to clients, as well as having sexual health conversations with clients; positive staff attitudes about, and preparedness for, providing sexual health information; and knowledge about sexual health. All were sustained at twelve months. Environmental enhancement with educational materials and condom distribution also increased.  相似文献
