3.2 An overview of Maxims of teaching: Simple to complex, Whole to part, Empirical to rational, Concrete to abstract, Known to Unknown, Particular to General;

Overview of Maxims of Teaching in Science and Mathematics

Maxims of teaching are the general principles or guidelines that help teachers present knowledge in a systematic, logical, and effective manner. These principles are based on the psychology of learning and the natural development of children. They guide teachers in selecting suitable methods, organizing content, and making teaching-learning more meaningful.

In Science and Mathematics, maxims of teaching are very important because these subjects involve facts, concepts, principles, reasoning, and problem-solving. By following these maxims, teachers can make difficult concepts easier and improve students’ understanding.

These maxims are not rigid rules. Rather, they are practical guidelines that help teachers teach according to the needs, abilities, and experiences of learners.

Meaning of Maxims of Teaching

The term “maxim” means a general rule or principle. Maxims of teaching are educational principles that guide teachers to move from easy concepts to difficult concepts, from familiar things to unfamiliar things, and from concrete experiences to abstract ideas.

These principles ensure that learning becomes natural, interesting, and effective.

Some important maxims of teaching are:

Simple to Complex
Whole to Part
Empirical to Rational
Concrete to Abstract
Known to Unknown
Particular to General

Simple to Complex

Simple to Complex is one of the most important principles of teaching. According to this maxim, the teacher should begin with easy and simple ideas and gradually proceed towards difficult and complex concepts.

Students understand simple things more easily. Once they have mastered basic concepts, they can understand advanced topics without confusion.

Meaning of Simple to Complex

Learning should proceed from easy content to difficult content. New knowledge should be built on previously acquired understanding.

Importance of Simple to Complex

Reduces fear and anxiety among learners.
Builds confidence in students.
Promotes gradual and systematic learning.

Increases confidence and motivation.

Limitations

It may not be possible to classify all topics as simple or complex.
Different students may perceive difficulty differently.

Whole to Part

According to this maxim, learners should first get an overall understanding of the whole concept and then study its individual parts.

Children generally understand a complete picture more easily than isolated details. After understanding the whole, they can analyze and study different parts in detail.

Meaning of Whole to Part

Teaching should begin with the complete unit or idea and then move towards its components.

Importance of Whole to Part

Provides a broad understanding.
Helps learners relate different parts.
Makes learning meaningful.
Develops analytical skills.

Application in Science Teaching

While teaching the human digestive system, the teacher first introduces the entire digestive system and then explains individual organs such as:

Mouth
Esophagus

Similarly, while teaching the solar system, students are first shown the complete solar system and then each planet is discussed separately.

Application in Mathematics Teaching

When teaching a geometrical figure like a triangle, the teacher first presents the complete figure and later explains:

Sides
Angles
Types of triangles
Properties of triangles

Advantages

Develops comprehensive understanding.
Encourages analysis.
Improves memory and retention.

Limitations

Some topics may require studying parts before understanding the whole.
Young children may find very large concepts difficult to grasp initially.

Empirical to Rational

This maxim emphasizes moving from experience to reasoning. Students first gain knowledge through observation and experience and then understand the scientific reasons behind it.

Learning through experience forms a strong foundation for logical thinking.

For example:

3 apples + 2 apples = 5 apples (experience).
3 + 2 = 5 (logical representation).

Advantages

Strengthens understanding.
Promotes scientific reasoning.
Encourages active learning.

Limitations

Some concepts cannot be directly experienced.
Practical experiences may require more time and resources.

Concrete to Abstract

This maxim states that teaching should begin with concrete objects and real experiences before introducing abstract ideas.

Reduces confusion.
Develops conceptual understanding.

Limitations

Some abstract ideas cannot easily be represented by concrete objects.
Preparation of teaching materials may require additional effort.

Known to Unknown

Known to Unknown is one of the most widely used maxims of teaching. According to this principle, the teacher should begin with the knowledge, experiences, and ideas that are already familiar to students and gradually introduce new and unfamiliar concepts.

Learning becomes easier when new information is connected with previous knowledge. Children understand unknown concepts more effectively when they are linked with things they already know.

Meaning of Known to Unknown

Teaching should proceed from familiar experiences and previously learned concepts to new knowledge and ideas.

The known facts act as a foundation upon which new knowledge is built. This principle is based on the fact that learning is a continuous process and every new experience is connected with earlier experiences.

Importance of Known to Unknown

Makes learning natural and meaningful.
Helps students understand difficult concepts easily.
Increases interest and motivation.
Promotes continuity in learning.
Prevents confusion and frustration.
Strengthens previous knowledge.

Psychological Basis of Known to Unknown

Children do not come to school with empty minds. They already possess experiences gained from their family, environment, and daily life. Effective teaching makes use of these experiences and connects them with new learning.

Thus, the teacher should identify the existing knowledge of learners before introducing new concepts.

Application in Science Teaching

Science teaching becomes more effective when concepts are related to daily experiences.

Example 1: Evaporation

Students already know that wet clothes become dry after some time. Starting from this familiar experience, the teacher explains the process of evaporation.

Known:

Drying of clothes.

Unknown:

Scientific concept of evaporation.

Example 2: Floating and Sinking

Children have seen leaves floating on water and stones sinking. The teacher uses these experiences to explain density and buoyancy.

Known:

Objects floating and sinking.

Unknown:

Density and buoyancy.

Example 3: Rainfall

Children know that rain occurs during the monsoon season. Using this knowledge, the teacher explains the water cycle and condensation.

Application in Mathematics Teaching

Mathematics is taught effectively when it is related to everyday life.

Example 1: Addition

Children know how to count objects like apples or pencils. The teacher uses these experiences to teach addition.

Known:

Counting objects.

Unknown:

Mathematical operation of addition.

Example 2: Measurement

Students know that cloth, rope, and rooms have length. Based on these experiences, the teacher introduces units such as centimetre and metre.

Known:

Everyday measurements.

Unknown:

Standard units of measurement.

Example 3: Percentage

Students understand marks obtained in examinations. The teacher uses this understanding to explain percentages.

Known:

Examination marks.

Unknown:

Percentage calculation.

Role of Teacher in Applying Known to Unknown

The teacher should:

Identify learners’ previous knowledge.
Relate new concepts with daily experiences.
Use examples from the local environment.
Encourage students to share their experiences.
Proceed gradually from familiar ideas to unfamiliar concepts.

Advantages of Known to Unknown

Makes learning easy and interesting.

Enhances retention and recall.
Creates a positive learning environment.
Encourages active participation.

Limitations of Known to Unknown

Students may have different background experiences.
Incorrect previous knowledge may lead to misconceptions.
Teachers need to understand learners’ individual differences.

Particular to General

Particular to General is another important maxim of teaching. According to this principle, teaching should start with specific examples, facts, or observations and gradually lead students towards general principles, rules, or laws.

This maxim forms the basis of the inductive method of teaching.

Meaning of Particular to General

Teaching should proceed from specific instances and observations to general conclusions and principles.

Students first observe examples and facts. After analyzing these examples, they derive a rule or principle.

Importance of Particular to General

Encourages active learning.
Develops logical thinking.
Promotes scientific attitude.
Helps students discover principles themselves.
Provides lasting and meaningful learning.
Improves reasoning ability.

Psychological Basis of Particular to General

Children learn more effectively when they are allowed to observe examples and derive conclusions on their own. Learning by discovery increases understanding and retention.

Therefore, students should first encounter concrete examples before studying general laws and principles.

Application in Science Teaching

Science teaching frequently follows this principle because scientific laws are derived from observations and experiments.

Example 1: Expansion of Metals

Students observe that metals expand when heated. After several demonstrations and observations, they conclude:

General Principle:

“Most metals expand when heated.”

Specific observations lead to a general scientific law.

Example 2: Photosynthesis

Students observe that green plants require sunlight for growth. Through experiments, they derive the general principle that plants prepare food in the presence of sunlight and chlorophyll.

Example 3: Reflection of Light

By observing reflections from mirrors, students derive the laws of reflection.

Application in Mathematics Teaching

Mathematics teaching also uses this maxim extensively.

Example 1: Sum of Even Numbers

Students observe:

2 + 4 = 6

4 + 6 = 10

8 + 10 = 18

After examining several examples, they conclude:

General Rule:

“The sum of two even numbers is always an even number.”

Example 2: Multiplication by Zero

Students examine:

5 × 0 = 0

10 × 0 = 0

20 × 0 = 0

From these examples, they derive the rule:

“Any number multiplied by zero gives zero.”

Example 3: Angle Sum of a Triangle

Students measure the three angles of different triangles and discover that their sum is always 180°.

Thus, they arrive at the general theorem:

“The sum of the interior angles of a triangle is 180 degrees.”

Steps Involved in Particular to General

Observation

Students observe facts and examples.

Comparison

They compare different observations.

Analysis

Similarities and relationships are identified.
