Call your child's school office and ask to speak to the principle. or contact your child's teacher by calling the school or waiting after class one day to speak with the teacher directly. Politely and respectfully express your desire to observe your child in his class for a day to gain insight into his behavior and academic performance and to learn what you can do to work with the teacher and school to help him excel.
Set a day where you can observe your child in class. Select a day when your child will engage in typical, or normal, classroom activities. Prepare for the observation opportunity by writing down two or three specific skills that you want to observe your child displaying (or not displaying). For example, you may be particularly concerned about your child's lagging vocabulary during home reading time. Write down "Vocabulary used" and "Pronunciation skills" or "Reading comprehension" in your journal. Ask the teacher ahead of time if he can accommodate a particular skill or activity that you're particularly interested in seeing your child perform.
Sit in an unobtrusive spot in the back of the classroom. Do not interrupt the teacher or the lesson at any time. When you observe something that you have a question about, don't understand or want further explanation on, make a note of it in your journal.
Record observations only about your own child and not the other children in the class. Take lengthy and detailed notes about everything you see your child do and say. Write down everything you notice, reserving analyzation for later.
At the end of the day or end of your observation time, thank your child's teacher for allowing you to observe him. Ask your questions or, if the teacher does not have time then to speak with you, arrange a time when you can discuss your observations.
