体育技能教学与健康素质发展互动学习方式的探析

分析认为,实现学生健康素质发展的培养目标,首先要确立技能教学与健康素质发展互动的学习方式。互动学习方式应从健康素质的内涵和指导思想,教学目标的确定、学习内容的选择、教学方法的创新运用等方面实施教学过程,以落实大学生健康素质发展目标,增强体育教学的效益。     

恢复能力的可训练性初探

实践运动中恢复作为训练课的从属部分,成为进一步冲击新的体能极限的瓶颈。能否另辟蹊径？将恢复作为训练课的主导内容!方法：大鼠147只,游泳训练2周。按36h超量恢复区间连续在训练后即刻、休息36h取样。结果：①血乳酸、血糖、血尿酸纵向比较;恢复幅度在前5区间呈增加趋势;②肝醣元：训练即刻组前6区间逐步上升,6×36h达峰值。恢复组前5区间维持在较高水平;③肌糖元：训练即刻组前4区间逐步上升,4×36h达峰值。恢复组前5区间维持在较高水平。结论：在小周期训练中,机体的恢复能力具有可训练性。     

艺术院校健美操选修课对学生体育能力培养的研究

通过对艺术院校健美操教学的实验研究,采用文献资料、调研、访谈、归纳分析等方法,探讨如何在健美操教学过程中,通过教学改革和教学手段培养学生对健美操的兴趣和爱好,从而提高学生的学习能力。     

小河沿文化陶器分群研究

小河沿文化陶器就器形及纹饰来源可以分为四群,即来源于赵宝沟文化、来源于红山文化、来源于大汶口文化和来源于庙子沟文化,其中前二者基本构成了小河沿文化的主体内涵,所以是小河沿文化的直接来源,大约在红山文化中期二者融合成小河沿文化。大汶口文化晚期,伴随着红山文化消亡,小河沿文化进入了一个发展的新阶段。     

以能力为本位提高高职英语教师素质研究

The impact of peer achievement and peer heterogeneity on own achievement growth: Evidence from school transitions

This paper estimates ability peer effects on achievement growth in reading and math. It exploits variation in peer characteristics generated at the transition from primary to secondary school in a sample of Berlin fifth-graders. As will be discussed in detail, this variation is exogenous in large parts. Results are similar for both achievement measures: pupils benefit from abler peers, but high-achievers do so to a smaller extent. The variance in peer skills has no impact on achievement growth – the corresponding estimates are negative, but insignificant.     

Development and Validation of a Multimedia-based Assessment of Scientific Inquiry Abilities

The potential of computer-based assessments for capturing complex learning outcomes has been discussed; however, relatively little is understood about how to leverage such potential for summative and accountability purposes. The aim of this study is to develop and validate a multimedia-based assessment of scientific inquiry abilities (MASIA) to cover a more comprehensive construct of inquiry abilities and target secondary school students in different grades while this potential is leveraged. We implemented five steps derived from the construct modeling approach to design MASIA. During the implementation, multiple sources of evidence were collected in the steps of pilot testing and Rasch modeling to support the validity of MASIA. Particularly, through the participation of 1,066 8th and 11th graders, MASIA showed satisfactory psychometric properties to discriminate students with different levels of inquiry abilities in 101 items in 29 tasks when Rasch models were applied. Additionally, the Wright map indicated that MASIA offered accurate information about students’ inquiry abilities because of the comparability of the distributions of student abilities and item difficulties. The analysis results also suggested that MASIA offered precise measures of inquiry abilities when the components (questioning, experimenting, analyzing, and explaining) were regarded as a coherent construct. Finally, the increased mean difficulty thresholds of item responses along with three performance levels across all sub-abilities supported the alignment between our scoring rubrics and our inquiry framework. Together with other sources of validity in the pilot testing, the results offered evidence to support the validity of MASIA.     

The male–female gap in post-baccalaureate school quality

Women are less likely than men to earn degrees from high quality post-baccalaureate programs, and this tendency has been growing over time. I show that, aside from the biomedical sciences, this cannot be explained by changes in the type of program where women tend to earn degrees. Instead, sorting by quality within degree program is the main contributor to the growing gap. Most of this sorting is due to the initial choice in which program type to apply to. No gender differences in selection with respect to ability or program quality arise as students progress through the admissions, enrollment or persistence choices.     

以释义为手段促进高级英语教学

在《高级英语》教学过程中,非常重要的一个环节就是对于课文的释义(paraphrasing),也是每一课的重点及难点。释义的环节直接影响到学生对于段落及篇章的理解程度,也会不同程度地提高学生语言表达能力和写作能力。有效地使用这一教学方法,对于提高学生的理解力和语言应用能力有较大的促进作用。     

用数理模型对体育分组教学进行预测与控制

为了使身体条件不同的学生在体育课中得到一定的锻炼效益,促使体育教师从多方面考虑和研究如何进行体育分组教学,以遵循“区剐对待”的教学原则,对不同情况的对象给予相应的指导,做到使体育优等生和体育差生的身体素质同步向前发展。在体育教学改革中实行体育“优生”和“差生”的分类教学,那么如何将学生分类呢?本文采用建立数理模型进行数值预测,计算出预测值与控制常数,从而达到对不同体育程度的学生进行分类,为广大教师提供切实可行的方法和科学依据。
