Metacognitive functions are important for both teachers and students to facilitate teaching and learning. The prefrontal cortex (PFC) plays a proven role in metacognition. As a pilot study, we evaluated the PFC activity of teachers and students using near‐infrared spectroscopy devices to explore the neural mechanism of PFC underlying metacognitive function during teaching and problem‐solving processes. In 14 student‐teacher pairs, participants in the teacher role gave hints via a tablet screen to facilitate solving of a tangram puzzle task by participants in the student role. The PFC activity of teachers increased after giving hints but not while planning hints. The PFC activity of students increased upon task solving after receiving hints. The PFC of teachers might play a metacognitive role in monitoring their own teaching results. The PFC activity of students might be related to the creativity process after gaining insights, as well as metacognitive process for monitoring their own behavior.  相似文献

The school setting represents the most common setting by which youth receive mental and behavioral health (MBH) services (Farmer et al., 2003, Psychiatr Serv, 54, 60–66). Nevertheless, many school psychologists are not providing MBH services despite the high prevalence of need. Additional research is needed to understand factors leading to these deficits, as well as potential solutions to ameliorate these concerns. The current study surveyed 341 school psychologists across seven states and found current ratios are one school psychologist for every 1,500–2,000 students. Study results suggest school psychologists are providing a half to full day of universal, prevention-oriented MBH services each week whereas more targeted, direct services (e.g., individual or small group counseling) are offered 1–4 hr each week. The school psychologist-to-student ratios also demonstrated a statistically significant and inverse association with the provision of targeted MBH services, with higher ratios resulting in fewer MBH services. Respondents provided potential solutions for how to expand the delivery of MBH services within schools, including increased awareness and support among school and district administrators, as well as access to training and professional development related to MBH services.  相似文献

Prodigious growth in out-of-school, private educational activities meant to supplement formal schooling is observed worldwide. Why has shadow education expanded, and what does it mean for the future of education in postmodern society? Illustrated by the historical development and recent changes in the Japanese shadow education industry, it is suggested that shadow education follows the institutional logic of formal education. And as this logic has become more homogenized and expansive globally, so have the forms and goals of shadow education. Because of its focus on learning and achievement, which are central to formal education, it is predicted that shadow education will be increasingly incorporated into the broader culture of education.  相似文献

Abstract

The aim of this cross-sectional study was to compare body composition and risk factors of lifestyle-related diseases between young and older male rowers and sedentary controls. Healthy males aged 19–73 years participated in the study, and were divided into four groups: 26 young rowers, 24 senior rowers, 23 young sedentary controls, and 22 senior sedentary controls. Total and regional lean soft tissue, fat mass, and bone mineral density were measured using dual-energy X-ray absorptiometry. The HDL-cholesterol of senior rowers (67.4 ± 13.4 mg · dl?1) was significantly (P < 0.05) higher than that of senior sedentary controls (59.2 ± 11.9 mg · dl?1), while HDL-cholesterol was similar in senior rowers and young rowers (66.1 ± 10.8 mg · dl?1). Arm, leg, and trunk lean soft tissue mass were significantly higher in senior rowers (5.6 ± 0.6 kg, 18.2 ± 1.8 kg, and 27.3 ± 3.2 kg respectively) than in senior sedentary controls (5.1 ± 0.4 kg, 16.3 ± 1.4 kg, and 24.6 ± 1.7 kg respectively; P < 0.05). Bone mineral density was also significantly higher in senior rowers than in senior sedentary controls (ribs, lumbar spine, and pelvic segments; P < 0.05). We conclude that age-related increases in the risk of lifestyle-related diseases, such as osteoporosis and sarcopenia, are attenuated in male rowers. These results suggest that regular rowing exercise may have a positive influence in the prevention of lifestyle-related diseases in older Japanese people.  相似文献

Toys can be used to promote children's cognitive, physical, motor, language, social, and emotional development. Safety and developmental appropriateness are of the utmost importance when selecting children's toys. Parents and teachers and other helping professionals need to teach children the safe use of toys to prevent toy-related accidents. Obtain additional information regarding toy safety by calling the U.S. Consumer Product Safety Commission at 1(800)638-CPSC.  相似文献

A four-session educational intervention at the Japanese senior high school level was conducted with 40 15-16-year-old male and female students. The purpose of the intervention was to break the silence pervading sex education at school and to help students question their understanding of sex, risk, contraception and love. Observations, questionnaires from the participants, and tape-recordings of each session were used to evaluate the effectiveness of the intervention. Sexual slang and euphemisms appear to be a relevant tool to enhance the communication between the teacher and students. Discussions about condom use demystified assumptions of young people as disembodied and desexualised beings. For most of the informants the negotiation of condom use was not a rational issue of individuals engaged in cost-benefit analysis.  相似文献

Recent research has documented silence/reticence among East‐Asian international students, including Chinese students, in Western/English classrooms. Students’ communication competence and cultural differences from the mainstream Euro‐American society have been identified as two primary barriers to participation. Placing emphasis on individual characteristics of Chinese students, however, without considering aspects of the educational context with which those characteristics interact, may over‐simplify and distort the mechanism underlying their silence in the classroom. Based on a qualitative study of Chinese students’ experience of sharing indigenous knowledge in classroom settings of Canadian academic institutions, it is argued that the pursuit of diversity in the classroom may be compromised by classroom interactions, through which, for instance, the dynamics and quality of the knowledge exchange of students from different socio‐cultural backgrounds may be adversely affected. Within this conceptual framework, the concepts ‘silence’, ‘culture difference’ and ‘indigenous knowledge’ are re‐examined; the concepts ‘reciprocal cultural familiarity’ and ‘inclusive knowledge sharing’ are advocated.
… [W]hen I did participate, mostly because I was required to. … Students took turns to present something and that is your topic. You have to say something but even then I didn’t feel that good because it seems … they didn’t feel that interested, … like they couldn’t follow my ideas, follow my perspective. And so it seems difficult to communicate. I think that is not just because of the language, it seems we see the same thing in different ways.
