生物学是一门实验科学,其绝大部分知识、观点、规律都来自实验,实验是学习、研究生物科学的重要手段。为此,笔者结合所在地区的实际,就生物教学中如何培养学生的科学素养进行了以下有益的探索,具体分述如下。一、实验能力的培养观察是积累感性认识,获取生物学知识的重要途径。在探究活动中,教师可以让学生自己设计实验方案,亲自实验,亲自观察实验现象。例如,在教学“用显微镜观察植物细胞”实验中,为了更好地引导学
Biology is an experimental science. Most of its knowledge, opinions and laws come from experiments. Experiments are an important means of studying and studying biological science. To this end, the author with the actual situation in the region, how to cultivate students' scientific literacy in biological teaching carried out the following useful exploration, the specific points are as follows. First, the cultivation of experimental ability Observation is the accumulation of perceptual knowledge, access to biological knowledge an important way. In the inquiry activities, teachers can let the students design their own experimental programs, experiments in person, observe the experimental phenomenon. For example, in teaching “experimentally observing plant cells with a microscope,” in order to better guide learning
