The meaning of teacher education in an exam-oriented education system: lessons from novice secondary teachers in Korea     

Jina Ro 《Asia-Pacific Journal of Teacher Education》2019,47(4):399-413

This study investigated four novice secondary teachers’ experience and perceptions of teacher education in relation to their current work experience in a high-stakes testing context. The novice teachers commonly indicated that their preparation, which had focused on content expertise, turned out to have little significance in schools, as they mainly executed teaching to the test. Instead, their role as homeroom teachers, which was concerned with caring and supporting students, was found to have much more significance. Accordingly, they indicated that teacher education must more strongly emphasise preparing teachers for that role, which requires them to become mature, considerate, and autonomous educators. Based on this finding, this study suggests the need for a clearer conception of and emphasis on the subjectification function of teacher education that is grounded in the consideration of the fundamental vision, purpose, and meaning of teacher education in a society.  相似文献

篮球专业学生功能性运动测试及结果研究     

王东礼 《体育科技文献通报》2015,(2):64-67,122

本文通过文献资料、实验法等,运用功能性运动测试(FMS),对某高校2011级部分篮球专选学生进行损伤情况调查及实验测试。结果表明:出现过轻度的人数为33人次,占总人数的89.1%,出现过中度损伤的人数为21人次,占总人数的56.7%,有过重度损伤经历的有7人次,占总人数的18.9%,损伤类型依次为皮肤擦伤、扭伤、肌肉拉伤、关节脱臼、骨折。最容易出现损伤的部位为手指、手腕关节。FMS测试6名学生中没有出现不及格现象。结论:体育教育专业篮球专项学生应加强对运动员损伤预防及伤后处理的教育,提高自我保护意识;加强场地器材和医务监督,从思想上重视损伤带来的危害。  相似文献   

Temporal specificity of training: intra-day effects on biochemical responses and Olympic-Weightlifting performances     

Achraf Ammar  Hamdi Chtourou  Khaled Trabelsi  Johnny Padulo  Mouna Turki  Kais El Abed 《Journal of sports sciences》2015,33(4):358-368

The aim of this study was to investigate the performance of an Olympic-Weightlifting session training at three times of the day on the performance related to biochemical responses. Nine weightlifters (21 ± 0.5 years) performed, in randomised order, on three Olympic-Weightlifting training (snatch, clean and jerk) sessions (08:00 a.m., 02:00 p. m., 06:00 p. m.). Blood samples were collected: before, 3 min and 48 h after each training session. Haematological parameters and markers of muscle injury were assessed. Resting oral temperature and rating of perceived exertion (RPE) were also assessed during each session. ANOVA showed that the performance was better (P < 0.001) at 02:00 p. m. with a less RPE (P < 0.01) compared to the morning and the evening sessions while there was higher (P < 0.05) oral temperature at 06:00 p. m. versus 08:00 a.m. and 02:00 p. m. Muscle damage changed immediately (without significant effect after 48 h) after the training sessions with lower values ??in the evening compared to the morning. In conclusion, the afternoon training is more effective than morning or evening sessions for weightlifters. Therefore, coaches and weightlifters should be advised to schedule their training session in the afternoon hour.  相似文献

Changing the English Classroom: When Large-scale ‘Common’ Testing Meets Secondary Curriculum and Instruction in the United States     

Sandra K. Cimbricz  Matthew L. McConn 《Changing English: An International Journal of English Teaching》2015,22(4):393-404

This article explores the intersection of new, large-scale standards-based testing, teacher accountability policy, and secondary curriculum and instruction in the United States. Two federally funded consortia – the Smarter Balanced Assessment Consortium and the Partnership for Readiness of College and Careers – prove focal to this paper, as these two organisations are creating new tests that will assess 42–49% of the K–12 student population in the United States in 2014–2015. Because greater teacher accountability for student performance will be given for these tests, there is more reason to pay attention to what these tests measure and what they do not. Our analysis suggests that these new tests will hold secondary English teachers accountable for literacy and disciplinary knowledge outside the field of English and thus raise important questions about what English teachers should, can and will do, especially when their jobs are on the line.  相似文献
