Some of the main advantages of class observation will include facilities to obtain additional information and provision of instant feedback. Teacher observations will provide best information that could not be provided by the other sources. Even the information provided by the observatory classes will provide several evaluation possibilities that could not be provided, evaluated and explained by any other materials. Thus, it will be better and it could also be a right choice to make use of the classroom observations and listening strategies of observations to learn established methods and features. The provision of instant feedback will help the students as well as the teachers to gain more benefits and several aspects of learning materials and facilities that could help them to improve the interaction and the observation in a very cost beneficial way. But the observatory classes will also have some bias and cons. The reflected evaluations and the economic background will make the students to observe the simple strategies and to leave the complex one. The unreliability and the effectiveness of classroom observation along with reduced time and time intervals will create more complexities and more afoul in several crucial cases. This may create distorted data and information, which reduces the belief and benefits in several rather ways.
