基于能力培养的数字电路与系统课程设计教学改进

本文主要分析数字电路与系统课程设计教学中存在的问题,从课设内容、课设项目设计的方法、强化实践技能等方面改进数电课设的教学,强化过程考核。培养学生理论联系实践的能力,强化数字系统的设计与分析,提高学生编程和自主解决问题的能力。

西门子S7-200 PLC面向实验室设计的不同方案

传统的PLC课程设计项目已不能满足学生掌握PLC在现代工业生产中的使用,结合学校现有PLC设备条件开发符合实际需求的课设项目。PLC课程设计及实训项目的多样化设计越来越重要,以西门子S7-200 PLC控制十字路口交通灯系统为例,介绍使用不同定时器个数的编程方案,拓展学生编程思维,使用不同机型、不同验证结果综合设计课设项目,通过这些多样化不同类型的训练,使学生掌握PLC相关的硬件软件、数字量控制,模拟量控制、变频器、触摸屏以及自动化生产线复杂控制等多门课程交叉融合,为学生未来的工程实践打下坚实的基础。

Mechanical Design and Students＇ Creativity ＂Think outside the Box＂

A design project was used in junior level mechanical design course to challenge the students＇ creativity skills. Beside the theoretical foundation of the course subject, the students were introduced to several professional skills such as： decision making tools, technical review meetings, interaction with customers, and teamwork skills. The design challenge was to develop a bike rack to meet a list of technical and marketing constraints. Details of the project requirements are presented with a brief overview of the main project mentoring tools. Students＇ creativity is discussed through two samples of the student work. It was noticed that, the basic creativity skills of the students can be improved by using some of the training tools, however, the students vary in their response to this training.
