Example of defining a theme:

My definition of "research on the creation of effective situation in primary school mathematics teaching under the background of new curriculum" is that "effective" mainly refers to the concrete progress or development that students have gained through teachers' teaching in a period of time. "Situation" is a kind of "atmosphere", which can stimulate people to actively associate, imagine and think, produce some kind of emotional experience and obtain some kind of image or thinking result. A good situation plays a positive role in the development of events, while a bad situation plays a negative role in the development of events.

"Effective Situation" Effective teaching situation can encourage students to imagine, think and explore actively and spontaneously (rather than under external pressure), to solve problems or discover laws, and it is accompanied by positive emotional experience. This kind of emotion is manifested in the thirst for knowledge, the desire and passion for exploring the objective world, the excitement for discovering laws and the love for teachers.
