To improve class participation:
We can divide the class into groups according to ability and aptitude---this creates a positive learning atmosphere and helps both weak and bright learners and it makes it easy for the teacher to give weak learners attention;
We should have students participate in group work, especially cooperative learning, in order to develop social and affective skills.
We can plan the participation--give instructions, objectives and time management guidelines at the onset--this saves time and the work is done;
We must give credit (bonus marks) and encouragement for participation in class activities and show our appreciation even if the students' response aren't completely correct;
We even may ask students to contribute materials, topics and ideas for their class--it boosts their confidence;
accept the learners' individual differences--let them work at their own pace;
We should assist while they work ---we should help students having problems;
We can provide general approval and support--tactfully regulate participation when brighter students dominate weaker ones;
We should help the students learn to set realistic goals
We should try to keep them using as much of the target language as is possible for them.
