校长在校本课程开发中的角色引领     

李明富  聂丽芳 《现代教育科学》2009,(3)

基础教育课程改革对课程开发权利进行了适当的调整,实行课程的三级管理制度,课程权利的下放赋予校长一定的课程开发权利,然而,目前的各级各类校长对校本课程开发和实施的引领并不是很成功,存在着各种各样的问题,如校本课程权利下放的缺乏,校长对校本课程开发认识的不到位,校长开发校本课程的专业知识和能力的缺乏,以"应试"为中心的考试评价制度对校本课程的影响等障碍.  相似文献

Complementary roles of care and behavioral control in classroom management: The self-determination theory perspective     

Youyan Nie  Shun Lau 《Contemporary educational psychology》2009

This study examined how classroom management practices—care and behavioral control—were differentially associated with students’ engagement, misbehavior, and satisfaction with school, using a large representative sample of 3196 Grade 9 students from 117 classes in Singapore. Results of hierarchical linear modeling showed differential relations. After controlling for students’ gender and socioeconomic status, both care and behavioral control were positively related to student engagement. Moreover, behavioral control was a significant negative predictor of classroom misbehavior and care was a significant positive predictor of satisfaction with school. Our findings underscore the importance of blending care and behavioral control to achieve multiple goals of classroom management.  相似文献   

Gastric carcinoma with osteoclast-like giant cells: a case report and review of the literature     

Li-duan Zheng  Xiu-ping Yang  Hua-xiong Pan  Xiu Nie  Jun He  Qing Lv  Qiang-song Tong 《Journal of Zhejiang University. Science. B》2009,10(3):237-241

Gastric carcinoma with osteoclast-like giant cells (OGCs) is an extremely rare tumor. So far, only six cases have been reported in the literature. Here we report an additional case of this tumor in a Chinese 78-year-old man presented with abdominal pain, vomiting, and hematemesis. Physical examination and gastroscopy revealed a tumor in the gastric antrum. The biopsy and pathological findings indicated a gastric adenocarcinoma with OGCs, which were present in both the tumor and the metastatic lymph nodes. Further immunohistochemical staining indicated that OGCs were reactive with CD68, CD45, and vimentin protein, but not with pancytokeratin, carcinoembryonic antigen, or epithelial membrane antigen, suggesting the monocytic/histiocytic derivation of these OGCs. In situ hybridization for Epstein-Barr virus showed no nuclear positivity in either adenoearcinoma or OGCs. Postoperative follow-up showed that the patient had survived for at least 6 months without recurrence. Further investiga-tion is warranted to clearly define the prognostic significance of OGCs in gastric carcinoma.  相似文献
