4. Teaching Approaches
and
Strategies for Science
The biggest challenge before a teacher is
how to teach Science lessons
(other subjects also)
If this teaching – learning activities are
effective, students can reach the goals of
life by acquisition of knowledge, skills
and values in Science.

5. Introduction
Students who are 10-16 years of age, are looking
forward to the future. They are actually
preparing for college or technical school or
focusing on simply graduating. This age group
may be distracted by many outside activities
and if they are not interested in science, it will
be a challenge for the teachers to teach them
in the classroom

6. Some students have a belief that….
Either SCIENCE is difficult or BOREDOM
But, Why do they think so ????
1/3/2019 6Pranabjyoti Das

7. There are lots of reasons. Some of them are…
1. Science is arrogant, so I don’t like science
2 Science is full of Mathematics. So I don’t like science.
3 Science is full of diagrams.
4 Science is full of formulae which are difficult to remember
5 Science is full of difficult terminologies.
6 Science is full of negativity. Scientists are always doubting things.
7 Science is mechanistic and cold, so I don’t like it.
8 The curriculum is boring.
9 The students have become worse at science.
10 Lack of examples in the classroom teaching
11 Lack of demonstration in the classroom.
12 The teaching is uninspiring.
So, what can be done now ???

8. Student engagement and understanding of the subject is given
more emphasis in today’s education system than spoon feeding
the facts.
Therefore, using black-boards or the typical lecture methods are
not adequate to teach science and other related subjects.
Many scholars and researchers have proposed advanced ideas
and they claim that virtual teaching scenarios or simulations can
help to build a better understanding of subjects amongst the
students.

9. Hands on Learning:
This is the best teaching method invented so far that involves the
active participation of students to experience scientific concepts
than to just have an audience view.
The use of low cost apparatus or home made models in the
classrooms will give the students a better opportunity to learn
science easily.
For example: Teachers can bring different
samples of soil, stones and other such materials
to the classroom while teaching the students
Rocks and Soil.

10. Story Telling:
Students love to hear stories and therefore, story telling is one of
the best ways to get their attention in class. Teacher can explain
the facts of biology or the laws of physics in the form of stories.
This is a mental organizer as human brains can remember stories
than just plain facts. Some teachers present the whole concept as
a story while some others use a story to open and end the session.

11. Be A Role Model
This innovative method is becoming an integral part of
science education as students can intellectually and
physically involve through activities while learning a new
concept.
Activities can be organized in classroom sessions where a
group of students can take the role of atoms or molecules
to study a chemical reaction or valency of atoms.

12. Visual clues:
The multi-sensory experiences improve their understanding
and memorisation. This includes drawings, diagrams, and
pictures to assist theory and setting up examples to show its
application side.
Using visual clues easily
supplements auditory
information and students
can easily connect better
with ideas.

13. Teach concepts, not facts…
Conceptual learning is an educational method that centers
on learning how to organize and categorize information.
Unlike more traditional learning models which concentrate
on the ability to recall specific facts, conceptual learning
focuses on understanding broader principles or ideas that
can later be applied to a variety of specific examples.
Thus a student can be made interested in science and
in other subjects too.

14. Improve the Image of Science
Children are natural scientists. They ask questions, pick
up sticks and bugs outside. They are curious about the
world around them. But as they get a bit older, many
kids gradually lose their interest in science.
They might see it as just another task at school,
something that doesn't apply to their lives. So a teacher
can remind the kids that science is everywhere and
most of these are fun for adults, too!

15. Motivate the Students
In order to keep the students interested in science , they must be
involved with the subject by third or fourth grade of their school
life. A teacher can nurture this attraction to science by making it
fun and interesting. We can do the followings for that….
1. Connecting Science to Students’ Everyday Life.
2. Exposing the Students to New Opportunities.
3. By involving the students in making models .
4. Teaching them to observe the things around.
5. By asking the students to teach each other.
6. Developing their confidence by asking easy questions.
7. Encouraging the students to think.

16. Teaching Approaches
And
Strategies for Science
The biggest challenge before a teacher is how to
teach Science lessons.
If this teaching – learning activities are effective,
students can reach the goals of life by acquisition
of knowledge, skills and values in Science.

17. Some of the important attitudes students will have
to learn while studying science are :
Curiosity
Honesty
Objectivity
Openness
Perseverance
Questioning or Doubt
Judgment
1/3/2019 17Pranabjyoti Das

18. Besides These, A Teacher Should…..
1. Try To Recognize The Problems Faced By The Students
2. Ask Relevant Questions of The Topic
3. Encourage The Students To Do Some Activity
4. Provide Consistent Descriptions and Explanations
1/3/2019 18Pranabjyoti Das

19. The 5-E Learning Cycle
A teacher must do the followings in the classroom…
1. Engage the students in topic
2. Explain the problem
3. Explore the idea of the student
4. Elaborate the findings
5. Evaluate

21. ‘Engage’ The Students…
An Example:
Now, to keep the students engage in the subject matter the teacher
must ask the students to
“Compounds are classified into Acids, Bases, and Salts.
Some acids and bases are strong while some are weak.
Acids are sour, Bases are bitter and Table Salts are salty.”
1. Find out the Names of the compounds in their homes
which are Acids, Bases and Salts.
2. Find out the uses of those Acids, Bases and Salts in their Homes
1/3/2019 21Pranabjyoti Das

22. Time is to “Explain”
Now the students must be asked to explain….
1. Why is the Lemon sour ?
2. Why is the Lemon Acidic?
3. Why is the Baking soda bitter?
4. Why is Baking soda Basic?
5. Why is the Table salt tastes salty?
This will help the students a better understanding
of the topic.
***However, if the students cannot reply, provide hints***
1/3/2019 22Pranabjyoti Das

23. “Explore” the Idea of the students
Make a list of the compounds found in our homes as follows….
1. Curd
2. Tea
3. Lime water
4. Soup water
5. Milk
6. Lemon juice
And ask them to find
out the compounds
with acidic and basic
properties.
And see How they reply in case of Tea & Milk.
Explore the understanding of the students.
If needed Explain the reason why Milk & Tea are neither Acids nor Bases
1/3/2019 23Pranabjyoti Das

24. Elaborate the “Issue”
From the previous list of the compounds students will easily find out that
Curd & Lemon Juice are Acidic
Lime water & Soup Water are Basic
But they may have problem in case of Tea & Milk
Here the Teacher has to Elaborate the topic explaining the
reason why Tea & Milk are neither Acids nor Bases.

25. Now it’s time to Evaluate
Evaluation plays an enormous role in the teaching-
learning process. It helps teachers and learners to improve
teaching and learning. Evaluation is a continuous process
and a periodic exercise. It helps in forming the values of
judgment, educational status and achievement of student.
Evaluation helps to measure the
validity and reliability of instruction.
Evaluation stimulates or encourages
the students to study.
Evaluation helps teachers to discover
the needs of the pupils.

Let us discus some examples
How would you apply yourself if you were asked by a student….
1. Why is the core of the earth hot ?
2. What is stone ?
3. What is environment ?
4. What is pollution ?
5. Why do we breathe ?
“KIDS DONOT REMEMBER WHAT YOU TRY TO TEACH THEM
THEY REMEMBER WHAT YOU ARE & HOW YOU REACT”

27. 1/3/2019 Pranabjyoti Das 27
We are 100% sure……
You will respond well and reply with a
confident smile
Because… Those Who Know, They Do
But, Those Who Understand, They Teach.
