ABSTRACT

Objective:

To improve the traditional teaching technique of using probe to destroy the brain tissue and spinal cord of toads.

Methods:

On the basis of the traditional teaching content, the distance of the probe entering the skull cavity and the specific feeling mark of destroying the brain tissue and spinal cord were added. Students were randomly divided into normal group and improved group according to the class. We observed the success rate and time spent on both the first and the second operations in the two groups.

Results:

The success rate of destroying the brain tissue and spinal cord in the improved group was high (93.2% vs. 72.3% for the first time). The secondary success rate was 97.7% vs. 85.1%, and it took less time (311.7±89.3) seconds vs. (511.6±171.1) seconds for the initial operation, The secondary operation time was (161.3±63.5) seconds vs. (266.0±98.2) seconds, with significant differences between the two groups (P<0.05).

Conclusion:

After the improvement of the content of destroying the brain tissue and spinal cord of toads in traditional teaching, it is easy to be mastered by students, with high success rate, less time spent, greater consistency with the 3R principle, and easier to be popularized and applied in teaching.
