Grit has been defined as passionate perseverance toward long-term challenging goals and it is associated with various positive outcomes for youth, including academic achievement. However, less is known about these associations for the two facets of grit (i.e., perseverance of effort, consistency of interest) and few studies have examined the link between grit and perceived social support. The present study examined the group-level demographic differences (i.e., gender, grade, socioeconomic status, and special education status) of grit in a high school sample (N = 1,077). In addition, direct associations between grit and perceived social support from multiple sources (i.e., teacher, classmate, parent) were examined, as well as a potential enhancing effect of social support as a moderator of the relation between grit and academic achievement. Results indicated positive associations among grit and its facets with social support from parents and classmates. Furthermore, the positive relation between grit and achievement was stronger for students reporting high social support from teachers, but not other sources (i.e., classmates, parents). Practical and theoretical implications for promoting student success are discussed.  相似文献

ABSTRACT

To maintain the accuracy of squash shots under varying conditions, such as the oncoming ball’s velocity and trajectory, players must adjust their technique. Although differences in technique between skilled and less-skilled players have been studied, it is not yet understood how players vary their technique in a functional manner to maintain accuracy under varying conditions. This study compared 3-dimensional joint and racket kinematics and their variability between accurate and inaccurate squash forehand drives of 9 highly skilled and 9 less-skilled male athletes. During inaccurate shots, less-skilled players hit the ball with a more open racket, demonstrating a difference in this task-relevant parameter. No joint kinematic differences were found for accuracy for either group. Coordinated joint rotations at the elbow and wrist both displayed a “zeroing-in” effect, whereby movement variability was reduced from the initiation of propulsive joint rotation to a higher consistency at ball-impact; potentially highlighting the “functionality” of the variability prior to the impact that enabled consistent task-relevant parameters (racket orientation and velocity) under varying conditions. Further, highly skilled players demonstrated greater consistency of task-relevant parameters at impact than less-skilled players. These findings highlight the superior ability of highly skilled players to adjust their technique to achieve consistent task-relevant parameters and a successful shot.  相似文献   

Hypocalcemia in an 11 Year Old Child: <Emphasis Type="Italic">A Difficult Case to Treat</Emphasis>     

P. Purohit  D. Khera  K. Singh 《Indian journal of clinical biochemistry : IJCB》2018,33(4):489-490

Hypocalcemia is a laboratory and clinical abnormality that is observed especially in neonates and paediatric patients. Laboratory hypocalcaemia is often asymptomatic but it can manifest as central nervous system irritability, paraesthesia, tetany (i.e. contraction of hands, arms, feet, larynx, bronchioles), seizures, and even psychiatric changes in children. Cardiac function may also be impaired because of poor muscle contractility. We report a unique case of an eleven year old male child who presented with chronic kidney disease associated with severe hypocalcemia, tonic-clonic seizures, hypovitaminosis D but normal electroencephalogram and electrocardiography. The child required prolonged intravenous calcium gluconate therapy to correct his ionised calcium levels.  相似文献

Diverging discourses: Examining how college students majoring in communication define diversity     

Drew T. Ashby-King  Lisa K. Hanasono 《Qualitative Research Reports in Communication》2019,20(1):9-18

Colleges and universities in the United States often promote diversity through a neoliberal lens by framing diversity as a celebration of individual differences or a commodity that students can gain by attending their institution. In communication courses, diversity has been conceptualized through both neoliberal and critical lenses, but limited research has investigated how communication students define and explain diversity. The focus of this study was to understand how communication students define diversity. We performed thematic analyses on open-ended survey responses to investigate how communication students define diversity. Four themes emerged from our analyses: (a) diversity is a mechanism for unifying communities, (b) diversity is an affirmation of individual differences, (c) diversity is a harbinger of acceptance and equality, and (d) diversity is a disruptive force that re-centers the voices of traditionally marginalized people. Our findings indicate most communication students define diversity through a neoliberal lens. However, 3% of our participants conceptualized diversity through a critical lens by explaining that diversity should create space for those who are marginalized to have their voices heard. We conclude by providing recommendations for communication instructors to incorporate more critical conversations about diversity into their classrooms and foster diverging discourses about diversity across communication curricula.  相似文献

The Socio-Cultural Image of Childhood (Based on an Analysis of Soviet and Russian Feature Films about Children)     

K.N. Polivanova  M.A. Shakarova 《Russian Education & Society》2018,60(4):348-369

The current state of childhood research is grounded in classical psychological theories, and Russian psychology is tied to cultural and historical theory in particular. These theories were invented to generalize and make sense of the realities of childhood as they existed at the time when these theories were created. Rapid social changes, especially during recent decades, have led to the emergence of a wide range of sources that bear witness to how the day-to-day life of childhood has changed. The understanding of childhood has continued to transform from one era to another. A metaphor was even coined to describe it, and at some point there was even a specific metaphor coined, “the disappearance of childhood.” This article seeks to explore how the image of childhood has changed in relation to the image of adulthood. As material for analysis, we chose Soviet and Russian movies from the 1940s to 2000s. The study is based on the assumption that a sequential analysis based on Yuri Lotman’s theory of the structure of the text demonstrates how the image of childhood changes over time. If in the 1940s and 1950s the child was presented as immature and not quite grown up, the adult was portrayed as the embodiment of the ideal form of the individual, and the main conflict was structured around childish immaturity, then gradually over the decades more and more main characters who were children and adults were portrayed as different kinds of individuals, and the child (or teenager) sometimes came to embody obviously negative features. The child–adult dichotomy itself lost its significance.  相似文献   

Food (in)security communication: a Journal of Applied Communication Research forum addressing current challenges and future possibilities     

Megan K. Schraedley  Hamilton Bean  Sarah E. Dempsey  Mohan J. Dutta  Kathleen P. Hunt  Sonia R. Ivancic 《Journal of Applied Communication Research》2020,48(2):166-185

ABSTRACT

This forum brings together food, (in)security, and communication. The authors participating in this forum center communication as both process and tool for understanding, mitigating, and making meaning of food (in)security. The nine authors together discuss the role of communication in food (in)security, the central challenges for scholars and practitioners working on food (in)security, and the creative possibilities and impacts influencing the future of food (in)security. The forum produces a call for applied scholars to re-imagine communication frameworks in order to make meaningful differences in their communities.  相似文献   

Preservice teachers perspectives and experiences teaching personal and social responsibility     

K. Andrew R. Richards  Jennifer M. Jacobs  Victoria Nicole Ivy  Michael A. Lawson 《Physical Education & Sport Pedagogy》2020,25(2):188-200

ABSTRACT

Background: Pedagogical models have become an established component of physical education over the past several decades. One such model, the Teaching Personal and Social Responsibility model, has gained momentum in practice and research, though little is known regarding its use in preservice teacher training. The model follows a flexible format focused on teaching life skills (e.g. leadership) that can be applied in all lived ecologies. Occupational socialization theory provides insight into the pretraining and teacher education experiences of preservice teachers that shape their understanding and practice of physical education and associated pedagogical models.

Aims: The purpose of this study was to understand the influence of a sequence of methods courses and early field experiences on U.S. preservice teachers’ understanding and implementation of the teaching personal and social responsibility model with youth from a community affected by poverty.

Method: This study took on a phenomenological and social constructivist approach. Ten preservice teachers (9 males, 1 female) took part in the study. The participants were an average age of 22.10 years old (SD?=?4.38) and seven identified as White and three as Black. Each participant was enrolled in methods and early field experience coursework that provided scaffolded training in primary education in a community affected by poverty. Preservice teachers team-taught groups of 10–15 children twice a week along with one day committed to on-campus reflection. Data collection included autobiographical essays, critical incident reports, reflective journals, non-participatory observations and field notes, and semi-structured interviews. Data were analyzed deductively through the lens of occupational socialization theory, and inductively as theory divergent trends were sought. Open and axial coding was completed with member checking throughout, resulting in a final set of themes and subthemes.

Findings: The preservice teachers initially struggled to connect with their students due to conflicting backgrounds, but the teaching personal and social responsibility model guided the relationship-building process. As the model was continuously utilized, more empathy and care were shown towards the children. Preservice teachers felt there was a lack of progression in positive behaviors but were able to empower youth and felt that the model was culturally relevant. Overtime, the students began to appreciate the affective domain despite the challenge of working in a community affected by poverty through frustration towards the larger system limiting any potential progress was present.

Conclusions: Subjective theories transitioned to include relationship building and life skills learning, likely because of the extended field experience and faculty support. The preservice teachers desire to connect with and teach the students well displays the connection between models-based practice and positive relationships. Preservice teachers’ knowledge of their students was limited as it was based on secondhand knowledge of youth, teacher educators, and school staff. Evidence indicates some cultural responsiveness development though there were also elements of a deficit model due to white privilege and class differences. Further work explicitly integrating a culturally relevant approach and social justice in teacher education programming should occur.  相似文献   

The link between student-perceived teacher talk and student enjoyment,anxiety and discursive engagement in the classroom     

Gaowei Chen  Jiahong Zhang  Carol K. K. Chan  Sarah Michaels  Lauren B. Resnick  Xiaorui Huang 《British Educational Research Journal》2020,46(3):631-652

This study seeks to understand the emotional connection of teachers' academically productive talk (APT) with student learning from the students' perspective. Using a sample of 2,225 students (N_{7th grade} = 1,146 and N_{8th grade} = 1,079) from 16 middle schools in a city of China, we investigate the relationship between students' perceptions of their teachers’ APT, student emotions (enjoyment and anxiety) and their discursive engagement with others in the mathematics classroom. Results from structural equation modelling and mediation analysis show that after controlling for gender, family resources and mathematics achievement, student-perceived teacher APT was positively associated with their discursive engagement with classmates. Furthermore, student enjoyment and anxiety in class mediated the relationship between student-perceived teacher APT and student discursive engagement with classmates. Multi-group analysis revealed that the model was invariant across genders and grades, indicating that the associations were applicable to male and female students as well as to seventh and eighth graders. These findings shed light on the emotional relationship of teacher APT with the discursive engagement of their students. Although prior research observes a positive relationship between teacher productive classroom talk and student discursive engagement primarily through classroom observations and teacher reflections, this study provides evidence from the students’ perspective and highlights the mediating role of student emotions in the relationship.  相似文献
