论文摘要
我们提出了一个简单但有效的概念，用于实现数学教学及其在理论力学中的应用，该教学在Covid-19-19-19大流行期间在意大利特伦托大学进行了构思，测试和实施。该概念预见了传统的黑板讲座，其中有少数学生在演讲厅中，而同一讲座则可以通过高质量的低型宽宽在线流媒体同时提供给其余学生。基于我们的第一个假设，即传统的黑板讲座，包括教授的手势和面部表情，仍然是一种非常有效的且高度赞赏的数学教学手段，本文故意不想提出一个新颖的教学概念，即如何通过在线教学概念来维持传统的黑板典范，并在线上介绍了在线质量，以使其在线质量以及如何在线上保持黑板的质量。低互联网带宽处的足够音频和视频质量。第二个假设是，数学的教学是一个动态的创造过程，需要在演讲厅作为听众的身体存在，以便教授可以根据他/她对他/她对学生的注意水平和学生表情的看法即时调整演讲的演讲。本文的第三个假设是，学生需要有可能亲自互动。我们报告了必要的硬件，软件和物流，以及与传统讲座相比，特伦托大学民用和环境工程的学生对拟议的混合讲座的感知，并与大流行病开始时需要作为紧急措施所需的纯在线讲座进行了比较。
We present a simple but efficient concept for the realization of blended teaching of mathematics and its applications in theoretical mechanics that was conceived, tested and implemented at the University of Trento, Italy, during the COVID-19 pandemic. The concept foresees traditional blackboard lectures with a reduced number of students present in the lecture hall, while the same lectures are simultaneously made available to the remaining students via high quality low-bandwidth online streaming. Based on our first assumption that traditional blackboard lectures, including the gestures and the facial expressions of the professor, are still a very efficient and highly appreciated means of teaching mathematics, this paper deliberately does not want to propose a novel pedagogical concept of how to teach mathematics, but rather presents a technical concept how to preserve the quality of traditional blackboard lectures even during the pandemic and how to make them available to the students at home via online streaming with adequate audio and video quality at low internet bandwidth. The second assumption is that the teaching of mathematics is a dynamic creative process that requires the physical presence of students in the lecture hall as audience so that the professor can instantaneously fine-tune the evolution of the lecture according to his/her perception of the level of attention and the facial expressions of the students. The third assumption of this paper is that students need to have the possibility to interact with each other personally. We report on the necessary hardware, software and logistics, and on the perception of the proposed blended lectures by students from civil and environmental engineering at the University of Trento, compared to traditional lectures and also compared to the pure online lectures that were needed as emergency measure at the beginning of the pandemic.
