生物知识具有综合性和开放性的特点,与课内知识相比,课外生物知识更加具备这些特征。为此,高中生在生物课内学习之余,还应该在课外更多地涉猎生物知识,拓展视野,扩大知识量,促进课外知识对课内学习的推动与完善。基于学习经验,从课外知识在高中生物学习中的重要意义入手,从三个方面分析了补充课外知识、提高生物学习效率的方法。 Biological knowledge has the characteristics of comprehensiveness and openness. Compared with class knowledge, extra-curricular biological knowledge more possesses these features. To this end, senior high school students in the biology class while studying, but also should be outside the class more biological knowledge, to broaden their horizons, expand the amount of knowledge and promote extra-curricular knowledge of the promotion and improvement of in-class learning. Based on the learning experience, starting with the importance of extracurricular knowledge in high school biology learning, the methods of supplementing extracurricular knowledge and improving the efficiency of biological learning are analyzed from three aspects.
