the lecture. The lecture is successful if the pupils have learnt well. The teacher can

and innovation according to Indian schools we can use this method effectively. Lecture
should be subject based and it should be in limited time. Listener should be given time to
think and they should ask the questions from time to time it means the listener should
participate in the lecture. Presentation should be effective and audio-visual should be used
during the lecture.
- LECTURER CUM DISCUSSION METHOD

not suitable for each and every topic and also for subjects. It can use as a main method and
other teaching methods can be used with it. The discussion method is the supporting method
and it can be used with the lecture method. Some social scientist says that it is a one of the
most valuable methods of teaching Environmental Science is discussion and “two heads are
better than one”. Wonderful results are achieved when a number of heads combine to solve
a problem.

participants are engaged in a process of competitive cooperation. Agreement is the
