What do I want to improve?
           I want to improve EMS model to promote student' idea about moon phenomena.

Why do I feel that something could be improved in what I am doing?
           From research in the past,I found that student at all level have misconception in astronomy.

What could I do that might improve what I am doing?
           I will build a model of Earth Moon and Sun,then I use the EMS model to demonstrate moon phenomena for improve student understanding about moon phase, face of moon and eclipse.

What data will I collect?
           Achievement test and semi structure interview.

Who might be willing to help me to strengthen the validity of my explanation?
           Astronomy teacher who have experience more than 5 years.
           Science educator.

Why do I believe in Earth Moon Sun model(EMS model)?
            One time,the idea of season is contradict to my common sense that if something closer to heat it will be hotter than the one is far,but the season occur because of the Earth's axis be tilted.
            Finally I found that the model can illustrate this idea effectively,when I put two thermometers at the Globe.One put at northern part and the other is placed at the southern part.I found that the temperature depending on earth axis not earth-sun distance.
