Frustration

I cried in front of my son telling him how frustrated I was.  I took them to Japan to travel. They didn't go to school for a week.  I ask them to write a journal about the trip and places we went.  He told me he will have it ready by end of this week. I asked for it yesterday and extended till today by noon.  The result was unacceptable.

I was so frustrated and felt like a loser mom.  I don't know what I did wrong and what more can I do.  It's all about the attitude.  It showed a lot of laziness in his work.  My husband saw me crying.  He told the kids that since they don't appreciate the trips we took them, we will stop doing that.
How do I motivate my children? How do I communicate with them in peace?
God, please help me.
