在职体育教师培训路径的思考   总被引：11，自引：0，他引：11  

张秀莲 《广州体育学院学报》2004,24(1):113-114,117

为适应新世纪高校体育教学改革需求，有效提高体育教学质量，对在职体育教师的培训必须综合考虑时间、经费和效果三方面的因素，制定出切实可行的培训方案除校内交流外，走出去与请进来相结合的基本思路是拓宽专业口径，拔高专业水平的有效措施：以请进来为主的培训路径，辅之以形成学习型团队或组织、制定合理的培训考核制度，将会在短期内提高在职体育教师整体的专业水平，拓宽专业口径，以解目前体育教学中存在的燃眉之急。  相似文献

The Issue of Range Restriction in Bookmark Standard Setting          下载免费PDF全文

Adam E. Wyse 《Educational Measurement》2015,34(2):47-54

This article uses data from a large‐scale assessment program to illustrate the potential issue of range restriction with the Bookmark method in the context of trying to set cut scores to closely align with a set of college and career readiness benchmarks. Analyses indicated that range restriction issues existed across different response probability (RP) values and item response theory (IRT) models if one were to apply the Bookmark procedure using intact test forms. Results also suggested that range restriction may still be present if one had access to additional data from an item bank. This demonstration critically highlights challenges that may exist in some practical applications of the Bookmark method due items not being designed to cover the full range of examinee abilities.  相似文献

Hip and upper extremity kinematics in youth baseball pitchers     

Taylor Holt 《Journal of sports sciences》2016,34(9):856-861

The purpose of this study was to examine the relationship between dynamic hip rotational range of motion and upper extremity kinematics during baseball pitching. Thirty-one youth baseball pitchers (10.87 ± 0.92 years; 150.03 ± 5.48 cm; 44.83 ± 8.04 kg) participated. A strong correlation was found between stance hip rotation and scapular upward rotation at maximum shoulder external rotation (r = 0.531, P = 0.002) and at ball release (r = 0.536, P = 0.002). No statistically significant correlations were found between dynamic hip rotational range of motion and passive hip range of motion. Hip range of motion deficits can constrain pelvis rotation and limit energy generation in the lower extremities. Shoulder pathomechanics can then develop as greater responsibility is placed on the shoulder to generate the energy lost from the proximal segments, increasing risk of upper extremity injury. Additionally, it appears that passive seated measurements of hip range of motion may not accurately reflect the dynamic range of motion of the hips through the progression of the pitch cycle.  相似文献
