The method we used here is so called “quasi-experimental design”, including “nonequivalent pre-and post-test control group design” and lag test in which the sample capacity is designed to 130 students from junior high school in New Taipei City. Half of the the students are conducted the interest experiments teaching and the other half conducted the conventional experimental teaching as the control. Firstly, for the students in high, medium and low-score region, the POE interesting experimental approach will interfere students and generate some invalid test, no matter for the experimental group and the control group. It is suggested that the interesting experimental will become the effective variable in the condition of applying the learning behavior and cognition , motivation in the experiments. Secondly, POE is effective in training the student scientific thinking if we treat the process of "understanding" and " expression" as the same thing. Thirdly, after applying the long POE teaching strategies, it will be helpful for students about the connection the new and old concept and for that students will encourage to answer the non-multiple choice question.POE實驗趣味實驗化學反應速率POE experimentsinterest experimentsthe chemical reaction rate
