实验设计是做好实验的第一步。实验设计技能是实验性科学研究者的必备素质。在中学生物学实验教学中,培养学生的实验设计能力,对增强实验预见性、减少实验失误、培养实验能力以及创造思维都有很大的作用,也是提高实验教学质量的有效途径。本文仅就笔者多年实验教学中的一些做法谈点浅见。一、指导学生撰写实验设计方案。一份目的明确、取材合理、步骤正确、条理清晰、准确度高的实验设计方案能使实验有条不紊,省时间且成功率高。一般来说,一份完整的实验
Experimental design is the first step in doing the experiment. Experimental design skills are an essential quality for experimental scientific researchers. In high school biology experiment teaching, cultivating students’ experimental design ability has a great effect on enhancing experimental predictability, reducing experimental errors, cultivating experimental ability, and creating thinking. It is also an effective way to improve experimental teaching quality. This article only discusses some of the author’s many years of experimental teaching. First, guide students to write experimental design programs. An experimental design scheme with clear objectives, reasonable materials, correct procedures, clear procedures, and high accuracy can make the experiment methodical, save time, and have a high success rate. In general, a complete experiment
