Teachers’ attitudes toward ethnic minority students might differ by students’ gender and the type of school teachers are working in because of different motivations for teaching and different school practices. Hence, the aim of the current research was to investigate elementary (n = 82) and secondary school (n = 82) teachers’ implicit and explicit attitudes toward male and female ethnic minority students. Teachers worked on either a male or a female Implicit Association Test and filled out a gender-specific questionnaire for measuring explicit attitudes. The results showed that elementary and secondary school teachers had negative implicit attitudes toward ethnic minority students, independent of students’ gender. Whereas secondary school teachers were implicitly more positive toward boys, elementary school teachers were implicitly more positive toward girls. Elementary school teachers were more enthusiastic about teaching ethnic minority boys than girls. The findings provide the first insights into differences in attitudes between elementary and secondary school teachers. 相似文献

Research on students’ motivation has mainly focused on interpersonal differences rather than on the ongoing, intrapersonal dynamics that forge students’ everyday life. In this five-month longitudinal (diary) study, we recruited a sample of 179 high school students from Greece (35.8% males; Mage = 16.27; SD = 1.02) to investigate through multilevel analyses the ongoing dynamics of students’ motivation. We did so by examining the relation between autonomous functioning and aspects of study regulation (namely, study efforts and procrastination) and well-being (namely, subjective vitality and depressive feelings). After controlling for perceived competence, we found week-to-week autonomous functioning to relate positively to study efforts and subjective vitality and negatively to procrastination and depressive feelings. Interestingly, implicit theories of ability - the degree to which one believes that ability is fixed or amenable - were found to moderate the week-to-week relations of autonomous functioning to study efforts and homework procrastination. In particular, autonomous functioning co-varied positively to study efforts and negatively to homework procrastination only among students who believed that ability is malleable. Also, beliefs that ability is fixed predicted poorer grades, lower mean levels of study efforts, and higher homework procrastination. The results underscore the necessity of taking a more dynamic view when studying motivational phenomena and the importance of jointly considering the implicit theory framework and self-determination theory. 相似文献

This study examined the contribution of situational probability information to the perceptual and cognitive processes underlying decision-making behaviour during in situ Karate performance. Experts and novices were required to make decisions about various attacks in different fight scenarios. The order in which the fight situations were presented was modified in order to provide advanced probability information and identify whether fighters were able to use the latter information to make better decisions. Specifically, one of the attacks was repeated every four actions. Results revealed that experts were more accurate and faster than their less skilled counterparts to block and counterattack the opponent. The experts picked up the occurrence of the attack pattern after the fifth repetition whereas novices did not. This enabled experts to improve decision time and decision accuracy. Findings suggest that such superiority could stem from the perceptual and cognitive skills possessed by the experts, thus giving them the opportunity to recognise a situation more easily. This was reinforced by gaze behaviour which demonstrated that experts used a more efficient search strategy involving fewer fixations of longer duration on a lesser number of areas relative to the novices. Moreover, experts generated more refined karate-specific knowledge structures compared with the novices. 相似文献

“I Heard it through the Grapevine”: Doctoral Student Socialization in Chemistry and History 总被引:2,自引:0,他引:2
Susan K. Gardner 《Higher Education》2007,54(5):723-740
Twenty doctoral students in the disciplines of chemistry and history were interviewed to better understand the socialization
processes that influence their success and how these processes differ by year in the degree program and disciplinary culture.
Five major themes emerged describing these socialization processes and how they facilitate or impede degree success, including
Ambiguity, describing the programmatic guidelines and expectations that surrounded much of the students’ experience; Balance,
pointing to the students’ need to balance graduate school responsibilities along with external relationships and demands;
Independence, describing the students’ desire to find equilibrium as they transitioned to the role of independent scholar;
Development, highlighting the significant cognitive, personal, and professional development that occurs in these students’
graduate experience; and Support, describing the faculty, peer, and financial support needed for the students’ success in
their degree programs. Suggestions for policy, practice, and further research are discussed. 相似文献

This paper examines 6th grade children's local conceptual development and mathematization processes as they worked a comprehensive
mathematical modeling problem (creating a consumer guide for deciding the best snack chip) over several class periods. The
children and their teachers were participating in a 3-year longitudinal teaching experiment in which sequences of mathematical
modeling problems were implemented from the 5th grade (10 years of age) though to the 7th grade. In contrast to traditional
problem solving, mathematical modeling requires children to generate and develop their own mathematical ideas and processes,
and to form systems of relationships that are generalizable and reusable. Reported here is a detailed analysis of the iterative
cycles of development of one group of children as they worked the problem, followed by a summary of the mathematization processes
displayed by all groups. Children's critical reflections on their models are also reported. The results show how children
can independently develop constructs and processes through meaningful problem solving. Children's development included creating
systems for operationally defining constructs; selecting, categorizing, and ranking factors; quantifying quantitative and
qualitative data; and transforming quantities. 相似文献

Verbal and nonverbal responses by alleged victims of child sexual abuse were coded for length, amount of information, and the manner in which they were elicited by the interviewer. In 16 of the interviews, anatomical dolls were employed for the purposes of demonstration, whereas they were not used in another eight cases matched with respect to other characteristics of the children and the alleged events. Children interviewed with dolls provided an equivalent number of details and spoke as many words in the substantive portion of the interview as did children interviewed without dolls, and interviewers in the two groups used similar probes to elicit information. However, the average responses by the children were significantly longer and more detailed when dolls were not used. Children gave longer and more detailed responses to open-ended invitations when dolls were not used. Caution is necessary when interpreting these findings. 相似文献
