在中学生物实验教学中,课程标准所倡导的探究性学习,有许多活动是通过实验来进行的。在生物学科的各种考试中,实验所占的比分都比较高,如江苏省的高考试题中实验或以实验为背景的试题占1/4,而实验类试题往往是学生学习的薄弱环节,这就要求高中生物教学应用合理的策略进行有效的实验教学,从而培养学生的实验探究能力。一、实验操作步骤的规范性高中生物实验中的操作步骤有明确的规定,而这些实验操作步骤是在长期的实践中总结出来的,
In high school biology experiment teaching, the inquiry learning advocated by the curriculum standards has many activities carried out through experiments. Experiments in the various subjects in the biology examinations are relatively high scores, such as Jiangsu Province, college entrance examination questions in the experiment or experimental background questions accounted for 1/4, and experimental questions are often the weak links in student learning, This requires high school biology teaching application of a reasonable strategy for effective experimental teaching, so as to develop students’ ability of experimental exploration. First, the experimental steps of the normative high school biology experiments in the steps clearly defined, and these experimental steps are summarized in the long-term practice,
