大学课堂教学中影响教学质量的主要问题是学生的学习态度,如何调动学生学习的积极性,是每位任课教师需要深入思考的问题。本文以材料力学课程教学为载体,结合管理学中的二八定律,以大学生力学竞赛为契机,研讨教师与学生之间的深层互动交流问题。深层互动分为课程授课中的互动和力学兴趣小组的互动两个层次,通过互动一方面为优秀学生打开上升通道,另一方面将优秀学生树为榜样,潜移默化中影响其他学生的学习态度,进而改善整个班级的学习风气。实践表明,深层互动教学模式能有效激发学生学习材料力学的兴趣,取得了良好的教学效果。

互动反馈是影响教学效能的重要因素.力学课程是工程领域重要的专业基础课,概念和计算方法较多,学生感觉难度很大.传统教学模式师生互动不足,反馈信息不全面,学生注意力易分散,教学相对低效.本研究尝试在力学课程中构建互动反馈教学模式.首先为全面精细反馈提供技术支持,创建应答技术系统--师生互动平台;然后通过实践探寻多元互动反馈模式在力学课程中的实施策略,并给出具体的案例展示.实践表明,多元互动反馈模式能有效提高教学效能. 相似文献

Exact, closed-form, solutions to a recent interactive buckling model proposed by Budiansky and Hutchinson (1979) are presented in full for the first time. These exhibit a form of Bifurcation involving looping equilibrium paths, identified recently from topological considerations, and are put forward as evidence of its typicality. A second, related, typical form is also identified in the response of the model. The predictions of two different asymptotic approaches, the first from traditional structural mechanics and the second making use of the mathematical concept of determinacy, are compared with the exact solutions. 相似文献

A comparative study with a vertically integrated model and the multi-level model has shown that the former can remain a good substitute for the latter in the prediction of sea-surface elevation as long as the bottom friction coefficients in the vertically integrated models are properly specified. 相似文献

It is proposed here to identify the law of crack length evolution with a small number of parameters governing a recently presented model (Rekik and Lebon, submitted for publication) describing the interface behavior in damaged masonry. Studies on non-confined medium- and large-sized masonry structures have shown that it is necessary to obtain a linear increasing crack in the post-peak part of the “stress–strain or –displacement” diagram. In confined masonry structures showing softening and sliding parts, the results obtained with this crack evolution failed to match the experimental data. The crack lengths identified in the post-peak part at several points on the experimental “stress–displacement” diagram show that the representative crack length is a bilinear or trilinear function describing the increase in the crack length with respect to the decrease in the shear stress. Numerical studies on medium- and large-sized masonry structures consisting of the same materials subjected to various loads were performed to determine the ultimate crack length, and the results are relatively insensitive to the size of the masonry and the type of the load applied. The numerical local fields determined in the elementary and full-scale structures investigated were used to test the validity of the present model at the local scale, as well as to obtain an additional unilateral condition in the case of compressed masonry structures in order to prevent overlapping between the masonry components. 相似文献
