As a fundamental course in science and engineering majors, how to deeply integrate college physics with professional courses and meet the needs of professional construction is an important content of college physics teaching reform. This article takes the mechanical engineering major as an example, combining college physics theory with practical engineering, and integrating engineering examples into teaching. It designs teaching examples such as analysis of the motion law of cam mechanism follower, gear transmission of servo motor reducer, energy conversion analysis of centrifugal water pump, utilization of waste heat for heating in heat pump systems, and capacitive inductive sensors. Using engineering examples to explain physics theory and achieve professional oriented university physics teaching.
After the college entrance examination in Hebei Province in 2021, the official did not release the reference answers. According to the commonly used teaching aids and teaching network platforms by students in various provinces and cities, there are two different answers to the question（3） of question 14. Based on this, the rationality of the two reference answers was discussed, and the reasons for the dispute of the reference answers were analyzed. It was found that the most fundamental reason was that some teachers’ examining topic skills were not in place, so the importance of examining topic was clarified.
初高中物理衔接问题一直是中学物理教师关注的难点问题.由学生熟悉的生活问题"厨房里的物理知识"创设情境,并将"厨房里的物理知识"主题贯穿于课堂始末,设计出基于生活情境的初高中物理衔接教学设计,以期为提高和完善初高中物理衔接工作的教学设计提供借鉴和参考.
针对民族地区地方院校生源特点,结合认知学习理论,提出构建一种大学物理教学内容系统化、教学方法多样化和教学手段多元化相融合的立体教学模式.在教学中将物理知识结构化、系统化,引导学生搭建整体-局部-整体的知识结构;通过教学方法和教学手段的优化,丰富学生的感性认识,培养学生理解、运用物理知识分析、解决问题的能力.
基于Python及OpenCV、Matplotlib和Pygame等库开发了一款在三线摆实验中集周期测量、图像绘制、数据处理及实验仿真等功能于一体的软件.实验时用摄像头模块记录下盘标志物运动,在软件内用OpenCV识别并解析数据、Matplotlib绘制实时运动图像、两套独立算法计算周期.此外自制数据记录板块可辅助学生数据处理,以Pygame搭建的二维实验仿真系统可辅助学生学习实验操作.
