Abstract
Background: With the microscopic interactive system widely used in experiment teaching of Genetics, Botany, Cell biology, Medical morphology, etc., which are focused on the microscopic observation, Traditional experimental teaching mode is changed, experimental teaching efficiency and experimental teaching effect are improving. Objective: In order to improve the efficiency and effect of genetics experiment teachingthis, we introduce the digital micro-network interactive system into the genetics experiment teaching. Method: We implemented the observation and preparation techniques of Drosophila salivary gland chromosomes from teaching organization, implementation of the experiment, using the digital micro-network interactive system. And the application effect of microinteractive system in chromosome section of Drosophila salivary gland is analyzed. Result: The results showed that the microscopic interaction system could improve the efficiency and effectiveness of the interaction between teachers and students, stimulate the students' experimental interest. Especially, the success rate of salivary gland chromosome is increased by more than 20%. Conclusion: The application of micro-interactive system has indeed revolutionized the traditional experimental teaching mode to a certain extent. It closely relies on modern information technology and forms a new experimental teaching mode for the cultivation of genetically innovative talents, which characterize by zero barriers in teacher-student interaction, zero distance in resource sharing and zero gap in real-time monitoring.
Highlights
Genetics is a discipline studying the laws of biological heredity and variation, and is an important professional basic course in the field of life sciences
The observation of drosophila salivary gland chromosome are used as an example to introduce the application effect of the microscopic interactive system in genetics experimental teaching, in order to provide a useful reference for the experimental teaching of related subjects
In the observation and preparation of drosophila salivary gland chromosome experiment, beginners generally lack an intuitive understanding of drosophila salivary gland
Summary
Genetics is a discipline studying the laws of biological heredity and variation, and is an important professional basic course in the field of life sciences. Huang Tiran et al.: Using Digital Micro-network Interactive System to Improve the Quality of Experimental Teaching of Drosophila Salivary Gland Chromosomes wasted while waiting for the teacher's guidance, because teachers should guide the students one by one [7]. Micro-network interactive system is a new means of modern laboratory teaching It is a networked and open interactive experimental teaching system, which uses digital technology and network transmission to organically connect the students' microscopes, teachers' microscopes and computers in the laboratory. It has powerful functions and is convenient to operate. The observation of drosophila salivary gland chromosome are used as an example to introduce the application effect of the microscopic interactive system in genetics experimental teaching, in order to provide a useful reference for the experimental teaching of related subjects
