This document discusses stimulus variation, which is the skillful changing of stimuli by a teacher to maintain student attention and participation. Maintaining stimulus variation is important for drawing and holding student attention, increasing memory and knowledge retention, encouraging student participation, promoting effective learning, and enhancing academic achievement. Some ways for teachers to vary stimuli include changing voice modulation, using charts/models/specimens, varying facial expressions and body gestures, incorporating demonstrations/activities, varying questioning techniques, and switching between oral and visual presentation styles. The document provides examples of how a teacher might vary stimuli when teaching about the topic of amoeba fission.

2. Stimulus
 Something that stirs or urges to action
 The reward was a stimulus for greater effort.
 An influence that acts usually from outside the body to partly change
bodily activity (as by exciting a receptor or sense organ)
 Light, heat, and sound are common physical stimuli.
 In classroom chart , model, activity ,demonstration , voice modulation etc.
are the common stimuli used by a teacher.

3. Stimulus- Variation
 The skillful change in the stimuli is known as the skill of stimulus variation.
 Just to avoid boredom, it is the teacher’s skills to stimulate the students,
increase their active participation, enthusiasm and spirit of study.
 Stimulus variation is a way of enhancing children learning by helping them
remain attentive.
 It is a way of maintaining students ‘ attention’.
 A teacher who is able to vary stimulus his/her lesson become effective as
there is high participation with learners and great achievements of the
lesson objectives.

4. Importance
 Draw and maintain attention of students
 Increase memory
 Knowledge retention
 Students’ participation
 Effective learning
 Complete information
 Interactive session
 Enhance academic achievement

5. Sub-skills
 Pause
 Voice modulation
 Chart/model/specimen etc.
 Facial expression/body gesture
 Demonstration/activity
 Variation in Questioning
 Oral-Visual Switching
 Variation in Interaction Style

1 Tell the name of any unicellular organism? Its Amoeba
2 ( chart showing fission of Amoeba) Students see
and listen
carefully

Sl. Pupil-teacher’s activity Students’ response
3 What do you see in this chart Amoeba fission
4 As you can see that organism like
amoeba splits in two cells during division
and it can take any place.
Students listen carefully
5 After replicating its genetic material
through mitotic division, the cell divides
into two equal-sized daughter cells. In this
method, two similar individuals are
produced from a single parent cell.
( with proper voice modulation& pause)
Students listen carefully
6 This process is called binary fission. Students listen carefully
