利用建构主义理论谈大学物理教学<br /> 与中学物理教学的衔接<br />
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 4
Abstract
本文通过阐述建构主义学习、教学理论的基本特征,提出利用建构主义理论处理大学物理教学与中学物理教学衔接问题的教学模式。该教学模式强调学生对物理知识的学习过程并不是学生对教师所传授知识的接受过程,而是以学生已有知识经验为基础积极的“意义建构过程”。

应用FLUENT模拟学生寝室内<br /> 污染物浓度变化规律<br />
采用数值模拟技术对建筑室内环境进行模拟仿真,可以形象、直观地对室内气流流动形成的微环境做出分析和评价。本文采用FLUENT数值模拟法,模拟了现有学生寝室污染物浓度场的变化规律,指出当前学生宿舍格局的不足,并将其适当改进,为更加...
油气悬挂在不同温度下非线性特性的无损评测
对不同温度下油气悬挂的非线性特性,提出了一种结合数学模型与遗传算法的反演方法。首先,应用反应实际气体状态的R-K方程和计算紊流阻力系数的Blasius公式建立了油气悬挂的数学模型,并验证了模型的正确性。然后根据数学模型,正向计算油...
