Time,Third Space,and Counternarratives of Achievement for Young Mothers in High School     

Elizabeth Chase 《Educational Studies A Journal of the American Educational Studies Association》2018,54(3):237-252

This article shares alternative conceptions of time in a qualitative study about the schooling experiences of teenage mothers. The counternarratives of three women of color are presented as alternatives for understanding temporally restricted discourses of achievement in high school. Using third space theory as a lens for understanding the participants' experiences, this article illustrates how each participant's school story creates room for thinking about school success differently. This understanding of participants' experiences provokes a deliberate reconsideration of time as it relates to student success and achievement in school. This article concludes with an analysis of the participants' counternarratives and implications for future work. This work is useful for practitioners and researchers in reconceptualizing difference among students and in creating room for school structures that support diversity in classrooms and schools.  相似文献   

Fear of injury in gymnastics: self-efficacy and psychological strategies to keep on tumbling     

Chase MA  Magyar MT  Drake BM 《Journal of sports sciences》2005,23(5):465-475

The aim of this study was to examine female gymnasts' fear of injury, their sources of self-efficacy and the psychological strategies used to overcome their fears. The participants were 10 female gymnasts aged 12 - 17 years. They had all taken part in competitive gymnastics and had experienced some type of injury during their careers. Individual interviews were conducted using a structured interview guide. Data were analysed using an inductive content analysis. The results indicated that gymnasts were most fearful of injuries because of the difficulty in returning from an injury and being unable to participate in practices and competitions while injured. Gymnasts described aspects of their past performance experience, such as success, consistency and communication with significant others, as important sources of self-efficacy. Some examples of psychological strategies used to overcome their fear of injury were mental preparation (e.g. imagery, relaxation), just "going for a skill" and the coaches' influence.  相似文献   

Physics students' understanding of relative speed: A phenomenographic study

It is important that students of physics develop both quantitative and qualitative understanding of physical concepts and principles. Although accuracy and reliability in solving quantitative problems is necessary, a qualitative understanding is required in applying concepts and principles to new problems and in real-life situations. If students are not able to understand what underlies quantitative problem-solving procedures nor interpret the solution in physical terms, it is questionable whether they have developed an adequate understanding of physics. The research reported here is part of a larger phenomenographic study that is concerned with the assessment of physics students' understanding of some basic concepts and principles in kinematics. In this article students' understanding of the concept of relative speed is described. A variety of ways of understanding relative speed and of viewing a problem that dealt with this concept were uncovered. The results are used to suggest ways for teachers to proceed in assisting students to enhance their understanding of this concept. The teaching principles outlined concern both teaching relative speed, in particular, and teaching scientific concepts and principles, more generally.  相似文献

Mothers' and Children's Conceptualizations of Corporal Punishment   总被引：2，自引：1，他引：2  

Thomas F. Catron  John C. Masters 《Child development》1993,64(6):1815-1828

Preschool ( M age = 4–11) and fifth-grade ( M age = 12–1) children and their mothers judged the acceptability of corporal punishment as a function of the type of transgression (dangerous, violation of social rule, or violation of moral precept) and discipline agent. Children of both ages and their mothers discriminated among different types of transgressions as a function of rule contingency, rule generalizability, and seriousness of the transgression. Social convention transgressions were judged to be more rule contingent, less generalizable (across settings), and less serious than prudential (dangerous) or moral violations, but overall children judged transgressions to be more generalizable than did their mothers. Preschool children showed broad acceptability for severe corporal punishment given any type of transgression, by any agent, whereas fifth graders were generally discriminating about limits of punishability, and their judgments appeared to be transitional between the broad acceptance shown by younger children and more focused acceptability shown by mothers. Mothers were proprietary with respect to agent and tended to focus on dangerous and moral violations as punishable. Findings suggest a developmental path from a single criterion for young children to consideration of multiple criteria for older children and adults. Judgments were also interpreted as reflecting social roles such as parents' responsibility to constrain children and children's expectations for constraint. Preschool children's broad acceptability of punishment despite their differentiation of classes of rules and of transgressions suggests that different constraints operate for judgments about rules or commands as opposed to sanctions. Implications for children's ability to identify and report abuse are also noted.  相似文献   

Item Discrimination: When More Is Worse     

Geofferey N. Masters 《Journal of Educational Measurement》1988,25(1):15-29

High item discrimination can be a symptom o f a special kind of measurement disturbance introduced by an item that gives persons o f high ability a special advantage over and above their higher abilities. This type o f disturbance, which can be interpreted as a form o f item "bias," can be encouraged by methods that routinely interpret highly discriminating items as the "best" items on a test and may be compounded by procedures that weight items by their discrimination. The type of measurement disturbance described and illustrated in this paper occurs when an item is sensitive to individual differences on a second, undesired dimension that is positively correlated with the variable intended to be measured. Possible secondary influences o f this type include opportunity to learn, opportunity to answer, and test wiseness  相似文献   

Māori feminism and sport leadership: Exploring Māori women's experiences     

Farah R. Palmer  Tina M. Masters 《Sport Management Review》2010,13(4):331-344

This paper utilizes Māori Feminism from an Indigenous, intersectionality perspective in order to give four Māori women sport leaders an opportunity to voice their experiences, especially with regards to ethnocultural and gendered identities. In particular, this paper explores pathways for these Māori women into and within sport leadership. It identifies barriers they experienced and strategies used to negotiate them; it analyses the affect of various identities during their experiences of sport leadership; and it critically analyses the impact that socio-cultural and structural factors have had on the well-being of these Māori women, and their effectiveness within the sport organizations they worked. The findings suggest the participants had a strong passion for sport, experienced mana (status and prestige) due to their sporting experiences and were motivated to take on leadership roles in order to give back (mahi aroha) to sport and/or their Māori communities. Barriers they faced included being whakaiti (modest and humble) in a male-dominated, highly competitive setting, institutional racism, sexism, marginalization due to their ethnocultural and gendered identities, as well as limited resources and lack of support from governing bodies. These barriers were negotiated by having suitable mentors, utilising their sporting and community networks, by brokering relationships with members of the governing body, adopting a partnership approach, and challenging ethnocultural and gendered expectations. All of the participants incorporated aspects of Māori culture and values such as whanaungatanga (kinship), manaakitanga (support) and aroha (compassion) into their leadership style and organizational culture with mainly positive outcomes. Catering to the quadruple bottom line (economic, environmental, social and cultural measures of business success) and adhering to culturally preferred ways of communicating and consulting did, however, place additional strain on these women. The participants reflected a hybrid style of leadership that integrated values and behaviours associated with their sporting, gendered and ethnocultural identities. Further studies on indigenous women in sport leadership need to take place in order to bring to the fore socio-cultural and structural issues that arise due to the intersecting of Indigeneity and gender. In addition, the combined impact that diversity management and gender equity policies have on Indigenous women needs investigating in order to progress the ‘managing diversity’ discussion in sport.  相似文献   

Pattern recall,decision making and talent identification in rugby union     

Sebastian Sherwood  Tiaki Smith  Rich S. W. Masters 《European Journal of Sport Science》2019,19(6):834-841

The ability to make fast, accurate decisions is an essential skill for all who play sport. However, measuring this ability has proved difficult for coaches and talent identification practitioners. Pattern recognition (a key factor in decision making) has commonly been measured using pattern recall tasks. This study aimed to understand whether accuracy when recalling rugby union patterns is a valid measure of on-field decision making performance. In Study 1, professional players recalled structured patterns of players from still images (N?=?20) viewed for 5?s. On-field decision-making markers, including coaches’ rankings of decision-making ability, playing position, number of years playing professionally and total number of years playing rugby union, were used as predictor variables of recall accuracy. Results showed that only total number of years playing rugby union was correlated with recall accuracy, suggesting that caution is necessary when adopting these tasks for talent identification purposes. The structured stimuli used in Study 1 were not representative of a true rugby union game, so Study 2 tested novice and expert players on a pattern recall task that included structured, semi-structured and unstructured rugby union patterns. Experts were significantly more accurate than novices when recalling structured and semi-structured patterns; however, there were no differences when recalling unstructured patterns. It was concluded that structured and semi-structured patterns should be used in future studies to test whether pattern recall tasks can be used for talent identification in rugby union.  相似文献
