Using blackboard (chalkboard) is a must for teaching in schools and colleges.
Though the technology has gone up with high visual interactive boards taking chalkboards, teaching with a chalkboard is still irreplaceable.
The chalkboard has many advantages both for the teacher and also the students.
Using the board makes the subject more narrative, easy to teach for the tutor, and lets the student understand better.
Advantages of chalkboard for teachers
Ease of presentation
A teacher can quickly deliver the subject by writing on the chalkboard. Students do not like oral presentations without some writing done.
For mathematics class
Here, the use of a blackboard is the only way to teach the students. With chalk, the teacher can write problems while students enter them into their notes.
For teaching English and other Languages
While learning languages, students find it difficult for some spellings; the teacher can write it on the board to help them copy into their notes.
The board is needed to draw diagrams for biology subjects like zoology, botany, biochemistry, etc.
Teachers can draw diagrams to help even students draw them in their books and thereby get practice for writing in exams.
In physics, derivation can be easily derived in a manner understandable to students by the use of a chalkboard.
In chemistry, the stoichiometry of equations, formulas, chemical reactions can well be taught by the use of the board.
Gain attention and interest of students in the subject
Students and audiences do not like long speech lectures.
They may remain interested for the first 10 min. or so, and their minds stay away from class.
This can be avoided by using chalkboard writing as both combinations of hearing and writing will keep their attention and interest in class intact for a longer time.
Writing on blackboards helps students
Writing on boar helps students take note of class.
This class note helps them to study the topic easily at home or during exams.
If it is shown on PowerPoint slides instead, the students find less time to note down the lecture.
The advantage for the students or audiences:
1. Ease of understanding
It is easier for the pupil to understand the topic on the blackboard as they see the method or procedure for some processes or theories.
2. Increased memory for a particular topic or diagram
For students seeing a topic on board is more memorable than just hearing it.
It is true that memory of sight is better than memory gained by hearing or speech.
It is also true that we remember people better by faces and not by their names.
3. Ease of making notes
Many students will like to have a running note of classroom teaching.
This is because of the ease of learning a student gets when he reopens the pages written during classroom teaching.
Writing on a blackboard gives ample time for the students to make their notes.
4. Stay attentive in class
Students listening to teaching mixed with oral and written presentations stay more attentive than mere speech mode of demonstration.
5. Better vision
To the students sitting at the back (benches/chairs), writing on board helps them to see better if the teacher’s voice is not audible in some words or sentences.
Advantages of using chalkboard over expensive interactive boards
a. An inexpensive teaching aid. The board and chalk used to write are cheaper than interactive boards or whiteboards.
b. Easily adaptable to everyone. The chalkboard look has an aversion and so is acceptable for everyone to see it.
c. Can be used in open air or room teachings. This is because of ease of carriage to the place, no requirement of electricity to power them, unlike interactive boards, and also they are not light-reflective so can be seen without strain on the eyes.
1. Chalk broad is time-consuming in topic coverage than interactive boards.
2. Less attractive and appealing than interactive boards.
3. The visual or virtual video presentation is not possible, which is more evident in understanding a structure like a biology etc.
So the uses of a chalkboard or interactive boards are quite essential for teachers or tutors for better teaching.
