'COURSE TITLE: 'INSTRUCTIONAL STRATEGIES IN STM
CODE: STM 312.
METHODS OF TEACHING SCIENCE
1. Demonstration Method: This is the method of teaching through example or experiments. A demonstration may be used to prove a fact through a combination of usual evidence and associated reasoning.
2. Lecture Method: This is the process of teaching by giving spoken explanations of the subject that is to be learned. Lecturing is often accompanied by visual aids to help students visualize an object or problem.
3. Teaching Method: This method involves students assume the role of a teacher and teach their peers. Students who teach others must study and understand a topic well enough to teach to their peers.
4. Discovery Method: This method enables the learner to generalize from simple experiences. It helps the students/learners find out thing and gain meaningful insight into the basic structure and processes of science and mathematics.
5. Auto-Instructional Method: This method consists of instructional materials that are prepared in a step- like fashion. The required to be done is usually programmed (in the computer).Learning from the programmed materials required active participation by the learner.
PERIOD: 1 (12:30 – 1:15)
