通过对生物必修教材内容的认真学习和一段时间的教学实践以及向学生的调查问卷和通过与甲种本、乙种本教材的比较,我们认为,生物必修教材改编得很好。其优点有以下几方面: 一、必修教材的封面和封底的设计以及书中增加的15幅彩图,既有较高的艺术性,又有较强的知识性,还有浓厚的时代感,很有特色,使学生物学的学生大有一见钟情的效果。二、课后习题数目增加,类型多样。甲种本和乙种本习题数目有限,题型单一,很不适合实际教学需要。必修教材节节有习题,内 By conscientiously studying the contents of compulsory biology teaching materials and the teaching practice for a period of time, as well as the questionnaires to students and the comparison with the A and B textbooks, we believe that the biological compulsory textbooks are well adapted. Its advantages include the following aspects: 1. The design of the cover and back cover of compulsory teaching materials and the 15 color pictures added in the book are not only highly artistic, but also have strong knowledge and strong sense of the times. With special features, students of learning biology have a love at first sight. Second, the number of exercises after class has increased and the types are varied. There are a limited number of exercises and a limited number of exercises, which are not suitable for practical teaching needs. The required textbooks have practical exercises within the section.
