The present study examined the relation between children's mastery motivation, self-assessment of performance, and task-related help-seeking behavior during task performance. Average-achieving black American children, varying in mastery motivation as measured by subscales of the Harter's Intrinsic-Extrinsic Orientation in the Classroom Scale, performed a multitrial verbal task and were given the opportunity to seek help on each trial after making a tentative response and assessing their performance by rating their confidence in the correctness of the response. A response-contingent payoff system was implemented to encourage children to restrict their help seeking to those instances in which they perceived that they could not make a correct response without assistance. As predicted, children's self-assessments of performance, regardless of their accuracy, appeared to influence help seeking more than the actual performance outcomes. Neither children's self-assessments of performance nor their overall rate of help seeking varied with level of measured mastery motivation. However, the type of help sought varied as expected with mastery motivation. Children characterized by high intrinsic orientations toward independent mastery in academic achievement contexts sought indirect help (i.e., hints) more often than they sought direct help (i.e., answers), whereas children characterized by low intrinsic orientations toward independent mastery showed no preference. These differences in motivational orientation influenced requests for help only when children perceived their initial solutions to be incorrect. These findings are discussed in the context of the analyses of help seeking as an instrumental learning and achievement strategy. The implications of the findings for analyses of black children's achievement styles are highlighted.  相似文献

This article shares the findings of a study investigating institutional policy definitions of plagiarism at twenty English-speaking Canadian universities. The types of primary sources consulted for this study included: (1) university academic calendars for 2016–2017, (2) institutional policies on academic misconduct, and (3) student academic codes of conduct. Sources were analyzed in comparative tabular and narrative form. Results show wide variation in institutional definitions of plagiarism as a specific subset of academic misconduct. The conclusions call for a coordinated effort among Canadian universities to develop a common framework of academic integrity that includes clear and explicit definitions for plagiarism, as well as other forms of academic dishonesty, that are consistent across provinces.  相似文献

Infants are increasingly cared for by adults other than their parents. Here we describe non-parental infant care within a diverse cohort; and investigate the relationship between parents’ antenatal intentions and actual infant care. 6822 New Zealand women were recruited during pregnancy and asked about their intentions for childcare. Non-parental care was assessed when infants were nine months old: 1717 (25%) of the 6853 cohort children were receiving more than 8 h per week of regular non-parental care. In comparison with infants of European mothers, infants of Asian or Pacific mothers were more likely to be cared for by extended family; and infants of Māori mothers were more likely to receive centre-based care. Infants from families with lower household incomes, living in more deprived areas were more likely to be cared for by family. When their infants were nine months old, mothers from low- to medium-income households were less likely to be using the type of non-parental care they had intended antenatally, and the same was true when their children were aged 2 years.  相似文献

Abstract

We examined earlier oral narrative and decoding and later reading in two samples spanning the first four years of reading instruction. The Year 1 sample (n = 44) was initially assessed after one year of instruction (M = 6; 1 years) and followed through their third year (M = 8; 1 years); the Year 2 sample (n = 34) assessed after two years of instruction (M = 7; 0 years) and followed to their fourth year (M = 9; 0 years). Oral narrative and decoding were assessed initially, oral reading, retell, and maze fluency, plus reading age, obtained at outcome. For the Year 2 sample, oral narrative and decoding contributed to oral reading and comprehension two years later. For the Year 1 sample, decoding contributed to most reading outcomes, with narrative quality uniquely predicting Year 3 retell fluency. Post-hoc exploratory analyses suggest story memory indirectly contributed to Year 3 reading via Year 2 retell.  相似文献

This paper explores organizational and peer dynamics that impact the potential for productive, trusting peer relationships. An in-depth phenomenological study of five peer coaching dyads was undertaken to examine the establishment and maintenance of peer coaching. Joint interviews were used to promote co-construction of responses. Findings suggested that formation of trust is impacted by values-based attachment, confidentiality, and the capacity of peers to make themselves vulnerable. Individual bonds are important at the start of coaching, but trust is further strengthened through contracting and reciprocity within the relationship itself and by an open culture within the organization. Organizational culture was found to influence trust and the need for a combination of benign organizational support, transparency, and non-intervention was seen as vital.  相似文献

This paper describes aspects of the real and hidden shortage of mathematics teachers. Possible causes of teacher shortage are discussed: salary levels, the image of teaching as a career, the image of mathematics, the diversion of mathematicians into the teaching of computing, and promotion of mathematicians into administrative positions. The effects of shortage on mathematics departments are also considered, in particular the effects on curriculum development, the role of the head of department, overloading of mathematics teachers, and the consequences of teacher shortage for certain pupil groups. With the current focus of attention on teacher shortage in certain subject areas, the paper raises a number of important points.  相似文献

This study examines audience duplication, the extent to which the audience of one program also watches the other, and its determinants. Using peoplemeter data from Guangzhou, a multichannel and multicultural television market in China, the study tests the intertwining effects of media structural factors and audience preference factors on audience duplication levels of program pairs. The results show significant effects of the two types of factors. A regression model was established in which these two types of factors together explained 59% of the total variance in audience duplication.  相似文献

This study adopts a network analytic approach to understand media audiences in relation to media markets, bridging the literature on audience behavior and media economics. Using audience data in the Chinese and U.S. markets, we apply multi-level measures to compare audience fragmentation patterns, a key indicator of market structure, across television channels. Drawing on McQuail's four–stage fragmentation model, we find the Chinese television market exhibits the Core-Peripheral model where a few channels dominate the marketplace and the rest are viewed by niche segments of the audience. In contrast, the U.S. market represents the Pluralism model with extremely high levels of audience duplication across channels, suggesting overlapping patterns of exposure throughout the market rather than isolated segments.  相似文献
