Computer-Based Learning Aids for Problem Solving in Mechanics of Materials

目前正在为选修材料力学课程的学生开发高度互动性、基于计算机的学习辅助工具。这些学习辅助工具以课件的形式，直接关注学生解决问题的能力的提升。涵盖的科目包括剪力和弯矩图，梁挠度，内部扭矩和旋转，内部载荷和应力在三维，应力转换，和轴向加载杆。一套基本的分析技能，关键的成功的主题形成了每个模块的基础。计算机练习(i)回顾相关理论，（ii）给出解决相关类型问题的逐步指导，（iii）邀请学生实际解决这些问题构成每个模块。在问题解决模式下，课件各模块提供即时反馈，并根据需要提供帮助和提示。由于这些模块会无限地产生新问题，学生可以在掌握所需的时间内使用这些材料。由于该课件还将设置日志文件，学生可以方便地完成作业并以电子方式提交。本课件与任何基于windows的平台兼容，需要最小的内存和存储空间，便于轻松集成到现有的材料课程机制中。

Highly interactive, computer-based learning aids for students taking mechanics of materials courses are under development. These learning aides, in the form of courseware, focus directly on the refinement of students' abilities to solve problems. Subjects covered include shear and bending moment diagrams, beam deflection, internal torques and rotations, internal loads and stresses in three-dimensions, stress transformations, and axial loading of bars. A set of fundamental analysis skills critical to success in the topic forms the basis for each module. Computer exercises that (i) review the relevant theory, (ii) give step-by-step instruction as to solving relevant types of problems and (iii) invite students to actually solve such problems constitute each module. In the problem solving mode, the modules of the courseware offer immediate feedback, as well as help and hint on an as-needed basis. Since the modules generate new problems ad infinitum, students can work with the material as long as necessary for mastery. Because the courseware will also set up log files, students can complete assignments as convenient and submit them electronically. This courseware is compatible with any Windows-based platform requiring minimal memory and storage, facilitating easy integration into existing mechanics of materials courses.
