Self-regulation ability is an important component of children's academic success. Physiological reactivity may relate to brain activity governing attention and behavioral regulation. Saliva samples collected from 186 preschool children (101 boys, mean age = 53 months, 34% minority) before and after a series of mildly challenging games and again 30 min following the challenges were used to assess hypothalamic–pituitary–adrenal (HPA) (cortisol) and sympathetic nervous system (SNS; alpha-amylase) activity. Behavioral regulation was measured in delay of gratification and slow-down motor activities included in the challenge task. Cortisol and alpha-amylase were related differentially to aspects of behavioral regulation. Low cortisol was related to classroom regulation difficulties. Children with greater cortisol elevations following the challenge task had poorer performance on the slow-down motor task. Children with greater increases in salivary alpha-amylase following challenge were less able to delay gratification. Results suggest that HPA axis and SNS arousal may contribute differentially to behavioral regulation ability.  相似文献   

Parental education, grade attainment and earnings expectations among university students     

Liam Delaney  Colm Harmon  Cathy Redmond 《Economics of Education Review》2011,30(6):1136-1152

While there is an extensive literature on intergenerational transmission of economic outcomes (education, health and income for example), many of the pathways through which these outcomes are transmitted are not as well understood. We address this deficit by analysing the relationship between socio-economic status and child outcomes in university, based on a rich and unique dataset of university students. While large socio-economic differences in academic performance exist at the point of entry into university, these differences are substantially narrowed during the period of study. Importantly, the differences across socio-economic backgrounds in university grade attainment for female students is explained by intermediating variables such as personality, risk attitudes and time preferences, and subject/college choices. However, for male students, we explain less than half of the socio-economic gradient through these same pathways. Despite the weakening socio-economic effect in grade attainment, a key finding is that large socio-economic differentials in the earnings expectations of university students persist, even when controlling for grades in addition to our rich set of controls. Our findings pose a sizable challenge for policy in this area as they suggest that equalising educational outcomes may not translate into equal labour market outcomes.  相似文献   

Fostering Cross Cultural Competence in Preservice Teachers Through Multicultural Education Experiences   总被引：1，自引：0，他引：1  

Jared Keengwe 《Early Childhood Education Journal》2010,38(3):197-204

Diversity is increasing in our classrooms implying the need for teachers to be prepared to work effectively with students from different backgrounds, such as cultural, linguistic or national origin. Additionally, the focus on diversity education is important because of the need for students to develop, from an early age, the ability to communicate with and relate to others from diverse backgrounds. This article focuses on cross cultural experiences gained from cross cultural partnerships between preservice teachers and English Language Learners over the course of a semester at a medium size public university. Evidence from this project suggests the need for teacher educators to model and support appropriate cultural competencies that are critical in classrooms that are fast becoming more culturally as well as linguistically diverse.  相似文献   

Using technology pedagogical content knowledge development to enhance learning outcomes     

Douglas?D.?Agyei  Jared?KeengweEmail author 《Education and Information Technologies》2014,19(1):155-171

This paper describes an intervention in which pre-service teachers developed their TPACK through multiple data sources. Teachers’ self-reports of their TPACK knowledge were triangulated with performance-based assessment of their instructional practices and artifacts to give a better understanding and nature of pre-service teachers’ TPACK development. Although self reported measures did not correlate with pre-service teachers’ actual increased knowledge of technology integration, this study enhances better understanding of the pre-service teachers’ TPACK development through the multiple assessment measures. The learning outcome measures provide specific information and concrete representation of what pre-service teachers can actually do with technology in their TPACK development. The findings suggested multiple concerns about self-reported measures that are discussed in the framework of the TPACK instrument.  相似文献   

Mobile learning and integration of mobile technologies in education     

Jared Keengwe  Malini Bhargava 《Education and Information Technologies》2014,19(4):737-746

Mobile technologies have a huge potential to transform education provided these technologies are designed and implemented in such a way that they are relevant to the social and cultural context of learning. Clearly, the application, implementation, and design of mobile technology in the global educational context pose technological and socio-cultural challenges. Specifically, technology tools and applications that are familiar in developed nations may pose unique challenges in developing countries, so ‘one size fits all’ or ‘one technology for all contexts’ does not practically work. Therefore, the authors provide case studies focusing on the pedagogical benefits of mobile technologies when used as educational tools. Ideally, this article is intended to stimulate reflections on the subject of m-learning as well as the integration of mobile technologies in education.  相似文献   

Information Communication Technology planning in developing countries     

Sandy Malapile  Jared Keengwe 《Education and Information Technologies》2014,19(4):691-701

This article explores major issues related to Information Communication Technology (ICT) in education and technology planning. Using the diffusion of innovation theory, the authors examine technology planning opportunities and challenges in Developing countries (DCs,) technology planning trends in schools, and existing technology planning models in schools districts in Dcs. Ideally, this article is intended to advance the discussion grounded on the premise that teaching is not effective without the appropriate use of information and communication technologies resources to facilitate student learning.  相似文献   

Promoting effective e-learning practices through the constructivist pedagogy     

Jared Keengwe  Grace Onchwari  Joachim Agamba 《Education and Information Technologies》2014,19(4):887-898

Although rapid advances in technology has allowed for the growth of collaborative e-learning experiences unconstrained by time and space, technology has not been heavily infused in the activities of teaching and learning. This article examines the theory of constructivism as well as the design of e-learning activities using constructivist principles. The manner in which constructivist theory supports e-Learning is explored, and extrapolating from this pedagogical theory, some implications are provided to model effective practices of the characteristics and capacities of this powerful learning environment.  相似文献   

A comparison of men's and women's strength to body mass ratio and varus/valgus knee angle during jump landings     

Haines TL  McBride JM  Triplett NT  Skinner JW  Fairbrother KR  Kirby TJ 《Journal of sports sciences》2011,29(13):1435-1442

The purpose of this investigation was to compare valgus/varus knee angles during various jumps and lower body strength between males and females relative to body mass. Seventeen recreationally active females (age: 21.94 ± 2.59 years; height: 1.67 ± 0.05 m; mass: 64.42 ± 8.39 kg; percent body fat: 26.89 ± 6.26%; squat one-repetition maximum: 66.18 ± 19.47 kg; squat to body mass ratio: 1.03 ± 0.28) and 13 recreationally active males (age: 21.69 ± 1.65 years; height: 1.77 ± 0.07 m; mass: 72.39 ± 9.23 kg; percent body fat: 13.15 ± 5.18%; squat one-repetition maximum: 115.77 ± 30.40 kg; squat to body mass ratio: 1.59 ± 0.31) performed a one-repetition maximum in the squat and three of each of the following jumps: countermovement jump, 30 cm drop jump, 45 cm drop jump, and 60 cm drop jump. Knee angles were analysed using videography and body composition was analysed by dual-energy X-ray absorptiometry to allow for squat to body mass ratio and squat to fat free mass ratio to be calculated. Significant differences (P ≤ 0.05) were found between male and female one-repetition maximum, male and female squat to body mass ratio, and male and female squat to fat free mass ratio. Significant differences were found between male and female varus/valgus knee positions during maximum flexion of the right and left leg in the countermovement jump, drop jump from 30 cm, drop jump from 45 cm, and drop jump from 60 cm. Correlations between varus/valgus knee angles and squat to body mass ratio for all jumps displayed moderate, non-significant relationships (countermovement jump: r = 0.445; drop jump from 30 cm: r = 0.448; drop jump from 45 cm: r = 0.449; drop jump from 60 cm: r = 0.439). In conclusion, males and females have significantly different lower body strength and varus/valgus knee position when landing from jumps.  相似文献   

Doctoral Student Socialization: Educating Stewards of the Physical Education Profession     

Jared Russell  Karen Lux Gaudreault  K. Andrew R. Richards 《Quest (Human Kinetics)》2016,68(4):439-456

ABSTRACT

In preparing the future stewards of the physical education profession, the occupational socialization and professional development of physical education doctoral students is important to consider. To date, there has been scant scholarly inquiry into doctoral education in physical education. However, there is an abundance of research related to doctoral training in the higher education literature more generally. Drawing upon this larger body of work, this article expands occupational socialization theory to address the socialization of physical education doctoral students and faculty members. The case is made that effective doctoral training in physical education is essential to securing the future of the profession. Provided is an overview of the existing literature, presentation of an adaptation to occupational socialization theory that explains doctoral physical education socialization, and a discussion of key professional development issues that academic leaders and student support personnel should consider. Implications and recommendations for doctoral physical education leadership and academic programs are provided.  相似文献   

The Relation between Attachment and Knowledge of Self and Mother in One-to Three-Year-Old Infants     

Sandra Pipp  M. Ann Easterbrooks  Robert J. Harmon 《Child development》1992,63(3):738-750

The relation between attachment to mother and knowledge of self and mother in 2 domains was assessed in 1- to 3-year-old infants. Infants' featural knowledge was measured by featural recognition, name, possession, and gender. In this domain, no difference between the 2 attachment classifications was obtained at 1 year of age, but significant and increasingly large differences between securely and insecurely attached infants were found at 2 and 3 years of age. The second domain measured infants' actions on self and mother in the context of symbolic play. Regardless of age, infants who were securely attached to mother acted on self and mother with greater complexity than did infants who were insecurely attached. Attachment was related equally to the complexity of infants' knowledge of self and mother. These data were discussed in the context of the development of infants' internal working models of attachment and the onset of representational ability.  相似文献
