Organizing all activities in this way makes the course truly learner-centered since students must take fall responsibility for carrying out each activity. As for seating, group members should arrange their seats or chairs in a small circle to encourage interaction.

小题4:________.

One important reason to circulate during activities is to keep track of the kinds of problems students have, such as grammatical accuracy, fluency, word choice, pronunciation and intonation discussion strategies, etc. However, it is generally not effective to correct students' errors when they arc involved in an activity The most practical way to deal with communication problems is to make notes of what you observe as you arc circulating. You can then use this information to provide feedback after the activity or to develop future lessons.

小题5:________.

Commenting on students' work does not necessarily mean grading them on the scene Even if the programs requires formal grades, you should try to put off assigning grades until later in the term.
