生物学是一门实验科学。在中学生物学教学中,通过实验教学可培养学生观察、动手的能力,为学生今后不论是进入高等学校进一步学习或是参加劳动生产打下了必要的基础。在实行会考时,我们应对实验能力的评价给予高度的重视。在制定实验能力评价标准时,要求学生做到: 1.提出问题及建立假说。 2.根据提出的问题,选择适当的试验材料,安全可靠的设备和适当的观察方法。 3.区分实验中的控制因素和可变因素。 4.收集和组织材料,把资料整理好。 5.根据观察和收集到的资料进行推论和判断。
Biology is an experimental science. In middle school biology teaching, experimental teaching can cultivate students’ ability of observation and practice, laying the necessary foundation for students to enter further study or participate in labor production in the future. In the implementation of the exam, we should attach great importance to the evaluation of experimental ability. In the development of experimental ability evaluation criteria, require students to do: 1. Ask questions and establish a hypothesis. 2. Based on the issues raised, select the appropriate test material, safe and reliable equipment and appropriate observation methods. 3. Distinguish between experimental control factors and variables. 4. Collect and organize materials, organize the data well. 5. Inferences and judgments based on observations and data collected.
