Teaching Reflection
The grammar lesson on present continuous tense went well,and most students could grasp the v.-ing rules and sentence structures. However, a few struggled with double-writing consonants when forming v.-ing, so more targeted practice is needed.Students were active in pair work for 3d,and the demonstration helped them understand the task clearly. Overall, the teaching objectives were achieved, and I'll prepare more varied exercises for tricky v.-ing changes in the next lesson.
