摘要
针对鸿蒙嵌入式系统课程实验技术复杂、实践要求高的特点,提出了一种多模块协同驱动的创新实验教学策略,其主要创新如下:(1)采用小熊派Hi3861和STM32F407两种开发板,通过不同开发思路和代码策略实现相同功能,设计出特色鲜明的鸿蒙训练项目;(2)提出三大教学方法:对比实验教学法,让学生直观体会平台差异;现象驱动教学法,激发学生主动探究问题根源;知识挖掘与创造发现法,引导学生构建关联知识体系。通过统计量分析、均方差检验、直方图和箱线图等方法对近3年教学数据进行实证分析,表明该策略显著提升了学生知识运用能力、问题解决能力和创新能力,有效培养了学生的自主学习意识,为物联网工程专业实践教学提供了新思路。
In consideration of the complex technical nature and high practical requirements of the Harmony OS embedded system course experiments,an innovative experimental teaching strategy driven by multiple modules is proposed.The key innovations include:(1)Utilizing two development boards,BearPi Hi3861 and STM32F407,to achieve the same functionality through distinct development approaches and coding strategies,thereby designing specialized Harmony OS training projects;(2)Proposing three teaching methodologies:the comparative experiment teaching method,enabling students to intuitively perceive platform differences;the phenomenon-driven teaching method,encouraging students to actively investigate the root causes of issues;and the knowledge mining and creative discovery method,guiding students to construct a connected knowledge framework.Through empirical analysis using statistical methods,mean square deviation tests,histograms,and box plots,the teaching data from the past three years are systematically evaluated.The results indicate that this strategy significantly enhances students'abilities in knowledge application,problem-solving,and innovation,effectively fostering their autonomous learning awareness and providing novel insights for practical teaching in the Internet of Things Engineering discipline.
