What is a Two-Dimensional (2D) Instructional Materials?

A two-dimensional (2D) instructional aterials consist only of lenght and width.

They are paper-based, opaque materials that are commonly found in classrooms.

This kind of materials do not need any special equipment for its use.

Boards

Graphic Materials

Photographs

Post Cards

Flash Cards

Graphic Materials

• Translates ideas and relationships into a

concrete form.• They are non-photographic, two-

dimensional materials designed to communicate a

message to the viewer. They often include verbal as

well as visual symbols.

• Graphics allow students to pick up

on things missed verbally, reduce

efforts in receiving messages, and they help focus attention.

Advantages

Graphic

Materials

Advantages

• It is readily available.• It can be easily carried from place to place.• It is inexpensive and can be reused.• It helps focus attention.• These convey certain types of information in a

condensed form.

Limitations

• This is not interactive.• It lacks depth and motion.• It can be easily misinterpreted.• This is written at a certain reading level.• It needs prior knowledge in order to interpret

or understand what is presented.

Best Practices in Using Graphics

• Use large visuals.• Use simple materials.• Cover irrelevant materials.• Use one at a time.• Teach learners how to interpret.• Ask questions for clarifications.

Pegboards

Hook and loop Boards

Chalkboards

Description

Advantages

Limitations

Description

• Most common instructional media found in classrooms, rural and urban alike.

• Chalk is used in writing on its surface and used as medium in verbal communication.

• Used as a surface where pictures, posters, graphs, charts, etc. are posted to supplement instruction.

Advantages

• It is generally suitable for different age groups, class size, and subject matter.

• No special skill is needed to be able to use it.• It is not dependent on electricity.• It is economical and reusable.

Limitations• It does not provide a permanent record.• If it is not well-situated, viewing the contents of the

board and reaching the top of the board becomes a problem.

• Good handwriting and knowledge on proper spelling is a necessity.

• Some information cannot be presented well using a chalkboard.

• Chalk dust can trigger asthma or respiratory problem.

Whiteboards and Magnetic Boards

Description

Advantages

Limitations

Description

• It has glossy surface, commonly white in color, where non-permanent markings are made with the use of special felt pens.

• Became popular around the 90s when there was a growing concern on the potential health risk of chalk dust.

• These kind of boards are basically have the same use and purpose of a chalkboard.

Advantages• Using markers does not generate dust that comes

from using and erasing chalk.• Whiteboard marker is easier to hold and write

compared to chalk and marking a white board takes less time.

Limitations

• It is more expensive than chalkboard and only special whiteboard markers are suitable for use on whiteboard.

• The white background can cause problems to those with vision impairment.

• Left-handed persons may find it difficult to write on these board because left-handed individuals usually write with their hand curved around the pen therefore causing their hand to drag across the strokes previously made.

Cloth Boards (Felt, Flannel and Carpet)

Description

Tips for Effective Use of Cloth Boards

Description

• This is a piece of plywood or heavy cardboard covered with either felt, flannel or carpet.

• The fuzzy surface of a felt, flannel, or carpet allows visual materials with appropriate backing to adhere.

• The ff. will hold to these kinds of boards: felt, flannel, sandpaper, pellon, scouring pad and yarn.

• Cloth boards are portable, simple to use, durable, colorful, and attractive.

• These kinds of boards are best use for drills, positioning exercise, describing flow patterns, explaining relationships, and for short term display.

Tips for Effective Use

• Place the board where all of your learners can have a good view of it.

• Since these kinds of boards are small group media, you may sit down as you present, with learners seated on the chairs or on the floor in a semicircle.

• Secure the board on an easel or lean it against a solid surface to ensure that it will not move during your presentation.

Tips for Effective Use

• Arrange display materials in proper presentation order.

• As you place the items on the board, press them against the cloth and shift it slightly to cause the two surfaces to interact and adhere.

• “Talk to the students, not to the board” and maintain eye contact.

• Store materials in a marked box.

Hook-and-Loop Boards ( Velcro Boards )

• In creating a hook-and-loop board, a plywood or heavy cardboard is covered with a nylon loop material and the

nylon hooks are adhered on the back of the instructional

materials to be displayed on the board.

• These boards are used in similar fashion with cloth boards.

• Its edge over the cloth board is that it has enough holding power to cause even heavy

materials to stay on the board

Pegboards

• Pegboards are made of tempered masonite with 1/8-inch holes drilled 1 inch apart.

• These boards are used in displaying three-dimensional objects or heavy materials with the use of hooks inserted into the board.

Bulletin Boards

Factors to Consider when Choosing an Area for Bulletin

Boards

Tips for Successful Bulletin Board Display

Definition

Definition• Bulletin boards are generally not used directly in

instruction but tend to be a supplement”( Kemp, J. & Smellie, D., 1994).

• They are used to introduce or follow up lessons presented.

• These boards are usually designed as an instructional device that can carry a message without the presence of a teacher.

• Other uses of bulletin boards are the following: for displaying notices and announcements, classroom rules and procedures, seasonal items and student work.

Factors to Consider when Choosing an Area for Bulletin Boards

• Select a place where there is a steady student traffic.• Avoid corners.• Avoid wall behind a desk.• Select a well-lighted place.• Place board on the wall at the reading level of your

learners.

Tips for Successful Bulletin Board Display

• Always update the information displayed.• Ensure that the display is neat and accurate.• Make sure there is balance between text and

graphics or pictures.• Make sure that the size of the text can be read from

a distance or the graphics o pictures can be seen from a distance.

Strip Drawings

Sketches

Cartoons

Posters

Charts

Graphs

Diagrams

Maps

Flip Charts

Drawing and Sketches

• Drawings and sketches employ the use of lines, either simple or crude. They may not be the real

thing but they may represent persons, places, things, and

concepts.• In general, drawings are more

finished and representational compared to sketches.

• There are times, when there is a need to illustrate something on the board. Therefore, sketching or drawing is an important skill that a teacher should learn in order to be understood as one

lecturers.

Cartoons

Definitions

Suggestions for the Use of Cartoons

Definitions• Cartoons are symbolism and oftentimes bold

exaggeration to present at a glance a message or point concerning news or events, people or situations.

• This pictorial representation of a person, idea or situation should be drawn around a single idea and presented in a challenging manner.

• Cartoons can be used as a springboard for a lesson, for a follow-up activity, or for evaluation purposes.

Suggestions for the Use of Cartoons

• Take into consideration the age and experience or maturity of the target learners.

• The cartoon should not contain so many details but only the essential features.

• Short and direct captions are used only when necessary.

• Use symbols that are clear and conventional. ( dove for peace, owl for wisdom, coffin for death, turtle for slow, etc.)

• Make sure that the cartoon is big enough to be seen.

Strip Drawings

It is a form of cartooning in which a cast of characters enacts a story

in a sequence of closely related drawings.

Strip drawing is a more accurate term for the commonly called

comic or comics strip (Dale, 1969).

Strip drawings can be used for motivation or starter for a lesson. It can also be used as an activity for students to express leaning gained. When making of strip

drawings, make sure that they are not only educational but also

entertaining.

Posters

Definition

( Heinich, R., Molenda, M., & Russel, D., 1993)

Examples

Organizational Chart

These show as organization’s structure or command. It illustrates the interrelationships between the different parts of an organization

Classification Chart

They are similar to organization charts but its purpose is to show the classification or categorization of objects, events, or species. An example is a chart showing the classification of plants or animals

according to characteristics or specie.

Time Lines

Time lines show in sequence different events or the relationship of people and events. To show the important

concepts, pictures or drawings are added.

Tabular Charts

They contain numerical information or data in a table or columns

Flowcharts or Process Chats

These kinds of charts show a process, sequence, or procedure.

Tree or Stream Charts

These kinds of charts show change, growth or development by beginning with a single course and then spreads out into many

branches or by beginning with many branches which then come together into a single channel.

Gannt Chart

A gannt chart is an activity time chart illustrates the start and finish dates of a certain activity or project.

GraphsIt shows quantitative data. These kinds of

graphics make analysis and interpretation of numerical information easier.

Examples

Line graph

They are used when plotting trends of relationships between series of data. It

shows the progress over a period of time.

Bar Graphs

Bar graphs are the simplest and easiest to read. The data are presented in horizontal or vertical bars. While the widths of the bars are the same, its length represents the amount or percentage data.

Pie Graph or Circle Graph

The section of these kinds of graphs represent the parts of a whole. These graphs always present whole amounts and

its parts are calculated in percentage or fractional parts.

Area o Solid Graphs

They are used to compare several related totals thru the use of geometric

shapes

Pictorial Graphs or Pictographs

These graphs utilize related pictures or drawings to show numerical data. It is an

adaption of the bar graph.

Diagrams

Diagrams are intended to show relationships or to help explain a process, how something works or how

something is constructed. It is any line drawing that shows the arrangement and relations as parts of the

whole, relative values, origins and development, chronological fluctuations, distribution, etc. (Dale,

1969)

Examples

Cluster or Cloud Diagram

This is used in a nonlinear activity wherein ideas, images, and feelings are generated around a stimulus word. It helps students see patterns in their ideas and help systemize the generation of ideas based upon a

central topic.

Chain of Events

This diagram illustrates the stages of an event, the actions of a character on the steps in a

procedure.

Fishbone Mapping

A fishbone map is used to show casual interaction of a complex event (like a nuclear explosion) or a complex

phenomenon (like leaning disabilities).

Cycle

A cycle illustrates how series of events interact to produce a set of results such as the life cycle.

Compare/Contrast

A diagram that is used to show similarities and differences.

Venn Diagram

A venn diagram is used to show relationships between sets, similarities and differences between

characteristics, stories or poem. It enables the students to visually organize similarities and differences.

MAPS (Flat Maps)

Political Maps-They show

territories and bounderies.

Physical Maps- They show data

like altitude, temperature,

rainfall, precipitation,

vegetation, and soil.

Commercial or Economic Maps- They show

variety of information like

the economic produce of the

different regions.

FLIP CHARTS

Resembling a small whiteboard, this stationary item is supported by

a four-legged easel or tripod and several sheets of paper are hinged

at the upper edge of the chart. Marker pens are used to write text

as well as figures and charts. A sheet can be flipped over to present information sequentially or for one

to continue a new page. A flip is best used in small group of

learners.

Pictures and Photographs

The generic term picture includes any kind of opaque representation

of visual images which includes drawings, photographs, pictures in

books and magazines, or any medium open to the artists’

interpretation. The term photograph only includes those images that were recorded by

a camera and is usually an exact representation of the original.

USES Qualities of Good Pictures

POSTCARDS

These are commercially printed with space on one side for an

address and postage stamp used for sending a short message

through mail.Postcards on a country’s scenic spots, heroes, or presidents are widely available in bookstores. They can be used in teaching in Social Studies or as items to be posted on the bulletin board.

FLASHCADS

These materials are used for drill activities in

teaching certain topics. Flashcards may contain

words, phases, sentences, math

combinations or pictures. They help develop skills

as well as atomizing responses of learners

The following are considerations in using flashcards ( Garo, 2007)

• Make sure that the flashcard is big and bold enough to be seen by everybody.

• Flash in a fast and snappy manner to develop fast thinking of response.

• Flash cards from back to front. Answer of each card should be written at the back so that as you flash, you can see the answer and check I the response is correct.

• Hold flashcard at chest level and make sure not to hide the words or math combinations on it.
