In order to meet the fourth grade science transfer exam, in the past month, teachers and students have made a lot of efforts to memorize scientific knowledge and train scientific answers. Specific actions are summarized as follows:

1. Organize knowledge points and outline key contents in class. In order to let students review scientific knowledge points quickly, I mainly sorted out the scientific concept knowledge of grades three and four, printed it into a book, and helped students outline the key contents in class. Students go home or read aloud at morning reading time to familiarize themselves with scientific knowledge.

2. Use "scientific fish" to organize students to do problems. When practicing in class, use the mobile phone to open the small program of scientific fish exercises, and use the projection to throw out the questions. The teacher will switch the questions, which can better train the students' answering speed. Practice 30 questions at a time. Students write the answers on the exercise paper, and then explain the answers after the answers. This can make students more focused and more efficient.

My reflection: we should pay attention to the combination of speaking and practicing scientific knowledge in daily teaching. In the fourth grade, students' homework mainly focuses on completing student activity manuals and copying scientific concept knowledge, because there is no workbook, and there are fewer opportunities to contact exercises at ordinary times. In the future science teaching, teachers can collect more related exercises and put them in ppt, and consolidate the exercises in time after the new lesson.
