随着多媒体设备和技术的飞速发展,多媒体技术在教学实践中得以广泛地运用,给课堂教学带来了巨大的变化。在中学生物教学中,应用多媒体技术可以增强实验的演示性,更容易理解微观知识,向学生更便捷、更直观地呈现生物科学前沿。本文将着力从以上几个方面加以论述。一、多媒体技术可以增强演示实验的可视性中学生物作为一门实验学科,教学中有大量的演示实验。然而由于受课堂布局所限,学生不能清晰地观察到实验现象,从而不
With the rapid development of multimedia equipment and technology, multimedia technology has been widely used in teaching practice, which has brought great changes to classroom teaching. In middle school biology teaching, the application of multimedia technology can enhance the demonstration of the experiment, make it easier to understand the micro-knowledge and make it more convenient and intuitive for students to present the biological science frontier. This article will focus on the above aspects to be discussed. First, the multimedia technology can enhance the visibility of demonstration experiments Middle school biology as an experimental discipline, teaching a large number of demonstration experiments. However, due to the limited layout of the classroom, students can not clearly observe the experimental phenomena, and thus not
