The chalkboard is one of those aids that is usually present in the classroom. Some are portable and others are fixed. You can write on them during classroom sessions. It is possible to use different colors of chalk for writing a topic, new words, exercises, illustrations, brainstorming ideas, writing drafts, drawing pictures.
Guidelines for Using Chalkboards
- Make sure everything needed for using the chalkboard should be kept ready before class begins.
- Clean the board before starting class and leave it cleaned after the class.
- Divide the board into two or three parts by drawing vertical lines.
- It should bear the date and the main topic of the day.
- Diagrams and pictures can be sketched before the class on a flip chart.
- Do not speak to the chalkboard. First talk to the class before writing on the board.
- Do not crowd the chalkboard with too much matter.
- Rub off the board periodically if you do not need the stuff.
- Ensure that the handwriting is clear and readable.
Advantages of Chalkboard
- 🚀 No advanced preparation required.
- 💡 The chalkboard is easy to use.
- 💰 It is almost always available and is cheap.
- 🧠 It helps to focus the students on the lecture.
- 📝 It is useful in building up maps, graphs, and diagrams.
- ✍️ It improves on writing skills of the person.

- 🧼 Can’t go back to something you’ve erased.
Flip Chart 📄
The flip chart is made of paper of different quality which you can write on using marker pens of different colors just like the chalkboard. The difference is that the flip chart is portable and can be pre-prepared where you can draw your illustrations prior.
Advantages of Flip Chart
- 💰 The flip chart is inexpensive.
- 🎒 It is easy to carry and the information does not have to be removed from the classroom; it can be referred to later.
- 🌈 It can be used to capture ideas during brainstorming, a lecture, or during revision.
- 🖌️ It can have diagrams and whatever else the teacher needs to show.
- 📆 The teacher can decide and prepare it in advance.
Disadvantages of Flip Chart
- 🖍️ It needs skill to use effectively.
- 📝 Most educators tend to use it as a scribbling surface (write on it carelessly) and fail to demonstrate its effective use.
- 📊 Flipcharts should be clear and simple with a few points only. They should not be cluttered with too much information. Color contrasts increase their effectiveness.
Charts and Models 📊🏭
These are already made visual aids usually used to display factual data in different forms.
- 📈 They emphasize the verbal content and can act as operational guides.
- 🏛️ Models provide three-dimensional visual impressions which might be difficult for the students to imagine.
- 🔄 They need to be revised at intervals to make sure they are up to date.

- 🧐 They stimulate interest.
- 🤔 They help students comprehend and remember complex information.
- 🙈 They are inappropriate for the visually impaired.
Handouts are well-planned documents prepared by the teacher for his/her students in order to promote their participation in the teaching-learning process. They ensure every student has access to the same information and can review that information whenever necessary.
Advantages of Using Handouts
- 🎯 Keeps you and students focused.
- 📚 Useful as study aids.
- 👥 Good for absent students.
- 🔁 Can cover previous material.
- 📝 Can include review or supplementary/look-ahead material.
- 🧾 Ensures consistency.
- 🔄 Reusable.
- 📖 Don’t facilitate deviation from the lesson plan.
- 📖 Might be considered a study-aid crutch where the teacher puts emphasis on reading the content instead of explaining.
- 📆 Some handouts are not up-to-date or may have brief contents.
A projector is an electrical device that enlarges words or diagrams on a screen or clear wall. It’s a very popular and versatile visual aid that has been made available to the modern-day lecturer.

- 👉 Use a pointer rather than fingers. Point on the machine, not on the wall (depends on pointer).
Computers are being used in teaching because they have the advantages of speed, accuracy in transmitting information; they are convenient and store large amounts of information. Once prepared, the teacher does not need to be there. Students can learn at their own pace.
- 🖱️ Computers do not provide adequate guidance for psychomotor skills. They need to be complemented by other methods.
- 🔌 Some may have short battery life span, so they are not reliable without electricity.
- 💾 Data can be lost when the devices get lost or do not function well.
- 💰 Computers are generally expensive for some schools.
