“假说一演绎法”在传统的中学生物教学中没有明确要求,但在《普通高中生物课程标准》中明确指出要求学生领悟。“假说一演绎法”是在观察和分析的基础上提出问题以后,通过推理和想象提出解释问题的假说,根据假说进行演绎推理,再通过实验检验演绎推理得出的预期结果。如果实验结果与预期结果一致,就 “Hypothesis a deductive method ” in the traditional high school biology teaching is not explicitly required, but in the “general high school biology curriculum standards” clearly pointed out that students need to comprehend. “Hypothesis-deductive method ” is based on the observation and analysis of the proposed problem, the hypothesis to explain the problem through reasoning and imagination, deductive reasoning based on the hypothesis, and then through experimental testing of the expected results of deductive reasoning. If the experimental results are consistent with the expected results, then
