Six-year scientific book "Phenomenon of Chemical Change"

Teacher and researcher Zhang first confirmed the success of this class, she said that she was very satisfied. Next, she made a careful review:

First, the overall thinking of science courses is relatively accurate. Science class is to cultivate students' ability to explore. The ability of hands-on experiment students can start from various phenomena, infer whether material changes have produced new substances, and then search for various evidences. Own assumptions to achieve the purpose of improving scientific inquiry ability.

Second, the introduction is simple and effective, and the attention of the students is firmly grasped in a short time.

Third, the activity is operability. The activities have clear goals, stimulating students' interest in scientific learning, and allowing students to develop their scientific literacy and inquiry skills. The core of the "activity" is to let students "hands-on". Pay attention to let students start from the "learning activities based on science and inquiry", and observe, record, organize, discuss and communicate in person... Only by letting them do it themselves can they develop their abilities and master scientific methods. Experiencing the joy of success and understanding the meaning of science can truly achieve the goal of “cultivating scientific literacy. The conclusions of the recommendations are drawn by the students themselves or together, although the conclusions they draw are not accurate and the language is not well-written. It is also owed to science, but as long as the students have done it themselves, they have experienced the science of science and technology, and their scientific literacy can be developed and improved.

The researcher also said that the student's spirit of seeking knowledge stems from the life around him. Therefore, our classroom teaching should pay attention to the students' life, close to the students' life, return to the students' life, pay attention to the students' personal experience, let the students think, think, understand, feel, and guide the students to discover the side. More interesting knowledge of life. Interest is the internal motivation for students to acquire new knowledge and participate in exploration activities. Stimulating students' interests is the key to improving the effectiveness of classroom teaching. We should clearly understand that "the science class is faced with the national students, their ability to pay attention is very short, and it is very easy to distract in the classroom and to do other things involuntarily." Therefore, we should pay attention to the interests of students, in-depth analysis of "what students like, hobbies," and use scientific means to fully mobilize students' enthusiasm, initiative, and initiative, and guide them to actively participate in the teaching process. Classroom teaching is a process in which students feel the knowledge and apply knowledge.
