生物学是一门实验性很强的学科,观察和实验是生物学教学的重要组成部分,也是提高生物教学质量的有效手段。我在多年的教学实践中指导学生动手制作些小型的生物标本,如:蝶类、蛾类、家鸽等生态标本,既可锻炼和培养学生的动手能力,又可改善教学条件,有助于激发学生学习生物课的兴趣和提高教学质量。最近我带领学生制作了三个家兔的剥制生态标本,供教学使用。剥制标本是将动物的皮连同皮外的被覆物一同剥下
Biology is a highly experimental discipline. Observation and experimentation are important components of biology teaching and an effective means to improve the quality of biology teaching. In my teaching practice for many years, I have been instructing students to make small biological specimens, such as butterflies, moths, pigeons, and other ecological specimens, which can both train and train students’ hands-on skills and improve teaching conditions. Stimulate students’ interest in learning biology courses and improve teaching quality. Recently, I led the students to produce the stripped ecological specimens of three rabbits for use in teaching. The specimen was peeled off by peeling off the animal’s skin together with the outer skin.
