Hi So-mi,
Be careful when you make comments, to directly relate them to the rationale. For example, your lesson's rationale states to use songs, chants, and rhymes to learn new phrases, but also to practice pronunciation, stress, and intonation. Did you think your lesson accomplished this? I think so, because children had a lot of chances to practice. I think you should put the article in front of the word (on your PPT), for example......... The snail has a shell. but ..... The butterfly has wings. Be careful, because you said "It has a long ears"..... but it is "It has long ears"
Also, I would pair up the students so they have more chances to practice speaking because students will get restless if they have to sit too long and listen to other people speak. Overall your lesson was challenging but that was good! I think it's good to challenge students.
Please really focus on reading each student's rationale and directly make comments about that. Thanx!
