【摘要】 《振动与声基础》是物理学中声学类专业的一门基础课程,也是一门理论与实验相结合的课程。课程内容主要是用数学方法分析振动与声的物理规律,在进行数学公式的推导过程中,会有大量抽象的较难理解的振动规律和声学现象,因此课程内容比较枯燥难懂,教材中大量的数理公式令人望而生畏。传统的教学方式是通过板书的形式进行公式推导,教师对公式进行解释和描述,这需要学生具备较高的逻辑思维能力和空间想象力。课程团队通过在《振动与声基础》这门课程的讲授中,采用线上线下混合式教学模式,将MOOC与虚拟仿真技术引入课堂教学,促使教学质量的提高,以适应新工科背景下应用型人才培养的需要。课程主要采取基于"BOPPPS"模型的理论教学模式、"线上线下+虚实结合"的实验教学模式,开展线上线下混合式教学的实践应用。更多还原

【Abstract】 "Fundamentals of Vibration and Sound" is a basic course for acoustics majors in physics,as well as a course that combines theory and experiment.The course content mainly uses mathematical methods to analyze the physical laws of vibration and sound.In the process of deriving mathematical formulas,there will be a lot of abstract and difficult to understand vibration laws and acoustic phenomena.Therefore,the course content is relatively boring and difficult to understand.There are a lot of textbooks.’S mathematical formula is daunting.The traditional teaching method is to derive formulas in the form of blackboard writing.Teachers explain and describe the formulas.This requires students to have high logical thinking ability and spatial imagination.The course team adopted the online and offline hybrid teaching mode in the teaching of the course "Basics of Vibration and Sound",introduced MOOC and virtual simulation technology into classroom teaching,and promoted the improvement of teaching quality to adapt to the application type in the context of new engineering.The need for talent training.The course mainly adopts the theoretical teaching mode based on the "BOPPPS" model,and the experimental teaching mode of "online and offline+ virtual and physical" to carry out the practical application of online and offline blended teaching.更多还原
