1. The research questions in this course are not proposed by me in a rigid wayide, but creating scenarios to demonstrate experiences and conversations so that students can proactively discover problems based on their own life experiences and want to do so. research questions themselves, which effectively stimulates students' enthusiasm and initiative in learning. Second, in fact, it is not easy for students to experience the process truly scientifically. Students' live activities in the classroom are not equivalent to the real scientific research process. ., Tangible, ungodly activities are not what we advocate. The key is to see if your instructional design is conducive to students playing their own role in activities and clearly realizing that they are the leaders of their own behavior and the masters of science. Investigative activities, whether the answer is right or wrong, must be the result ofan investigation and research. My goal for this class is to give students plenty of time to add salt one spoonful at a time, while stirring, observing, and recording. , so that students can truly experience the scientific research process. 3. When designing this lesson, students were not informed about the methods to use for research and how to use them specifically, considering the students' actual situation. of 100 ml was proposed. How to formulate a research plan was left to the students for further discussion. This provides a creative space for students to conduct scientific research independently.
