 ENG201 Assignment # 4 Idea Solution Spring July 2012

Answer 1:

Types of Visual Aids:

Objects

The use of objects as visual aids involves bringing the actual object to demonstrate on during the speech. For example, a speech about tying knots would be more effective by bringing in a rope.
Pro: the use of the actual object is often necessary when demonstrating how to do something so that the audience can fully understand procedure.
Con: some objects are too large or unavailable for a speaker to bring with them.

Models

Models are representations of another object that serve to demonstrate that object when use of the real object is ineffective for some reason. Examples include human skeletal systems, the solar system, or architecture.
Pros: models can serve as substitutes that provide a better example of the real thing to the audience when the object being spoken about is of an awkward size or composure for use in the demonstration.
Cons: sometimes a model may take away from the reality of what is being spoken about. For example, the vast size of the solar system cannot be seen from a model, and the actual composure of a human body cannot be seen from a dummy.

Graphs

Graphs are used to visualize relationships between different quantities. Various types are used as visual aids, including bar graphs, line graphs, pie graphs, and scatter plots.
Pros: graphs help the audience to visualize statistics so that they make a greater impact than just listing them verbally would.
Cons: graphs can easily become cluttered during use in a speech by including too much detail, overwhelming the audience and making the graph ineffective.

Maps

Maps show geographic areas that are of interest to the speech. They often are used as aids when speaking of differences between geographical areas or showing the location of something.
Pros: when maps are simple and clear, they can be used to effectively make points about certain areas. For example, a map showing the building site for a new hospital could show its close location to key neighborhoods, or a map could show the differences in distribution of AIDS victims in North American and African countries.
Cons: inclusion of too much detail on a map can cause the audience to lose focus on the key point being made. Also, if the map is disproportional or unrealistic, it may prove ineffective for the point being made.

Tables

Tables are columns and rows that organize words, symbols, and/or data.
Pros: Good tables are easy to understand. They are a good way to compare facts and to gain a better overall understanding of the topic being discussed. For example, a table is a good choice to use when comparing the amount of rainfall in 3 counties each month.
Cons: Tables are not very interesting or pleasing to the eye. They can be overwhelming if too much information is in a small space or the information is not organized in a convenient way. A table is not a good choice to use if the person viewing it has to take a lot of time to be able to understand it. Tables can be visual distractions if it is hard to read because the font is too small or the writing is too close together. It can also be a visual distraction if the table is not drawn evenly.

Photographs

Pros:Photographs are good tools to make or emphasize a point or to explain a topic. For example, when explaining the shanty-towns in a third word country it would be beneficial to show a picture of one so the reader can have a better understanding of how those people live. A photograph is also good to use when the actual object cannot be viewed. For example, in a health class learning about cocaine, the teacher cannot bring in cocaine to show the class because that would be illegal, but the teacher could show a picture of cocaine to the class. Using local photos can also help emphasize how your topic is important in the audience's area.
Cons: If the photograph is too small it just becomes a distraction. Enlarging photographs can be expensive if not using a power point or other viewing device.

Drawings/Diagrams

Pros: Drawings or diagrams can be used when photographs do not show exactly what the speaker wants to show or explain. It could also be used when a photograph is too detailed. For example, a drawing or diagram of the circulatory system throughout the body is a lot more effective than a picture of a cadaver showing the circulatory system.
Cons:If not drawn correctly a drawing can look sloppy and be ineffective. This type of drawing will appear unprofessional.

Visual Aids Media: Simple to Advanced

Chalkboard or Whiteboard

Chalkboards and whiteboards are very useful visual aids, particularly when more advanced types of media are unavailable. They are cheap and also allow for much flexibility.  The use of chalkboards or whiteboards is convenient, but they are not a perfect visual aid. Often, using this medium as an aid can create confusion or boredom. Particularly if a student who is not familiar with how to properly use visual aids attempts to draw on a board while they are speaking, they detract time and attention from their actual speech.

Poster Board

A poster is a very simple and easy visual aid. Posters can display charts, graphs, pictures, or illustrations. The biggest drawback of using a poster as a visual aid is that often a poster can appear unprofessional. Since a poster board paper is relatively flimsy, often the paper will bend or fall over. The best way to present a poster is to hang it up or tape it to a wall.

Handouts

Handouts can also display charts, graphs, pictures, or illustrations. An important aspect of the use of a handout is that a person can keep a handout with them long after the presentation is over. This can help the person better remember what was discussed. Passing out handouts, however, can be extremely distracting. Once a handout is given out, it might potentially be difficult to bring back your audience’s attention. The person who receives the handout might be tempted to read what is on the paper, which will keep them from listening to what the speaker is saying. If using a handout, the speaker distributes the hand out right before you reference it.Distributing handouts is acceptable in a lecture that is an hour or two, but in a short lecture of five to ten minutes, a handout should not be used.

Video Excerpts

 A video can be a great visual aid and attention grabber, however, a video is not a    replacement for an actual speech. There are several potential drawbacks to playing a video during a speech or lecture. First, if a video is playing that includes audio, the speaker will not be able to talk. Also, if the video is very exciting and interesting, it can make what the speaker is saying appear boring and uninteresting. The key to showing a video during a presentation is to make sure to transition smoothly into the video and to only show very short clips.

Projection Equipment

There are several types of projectors. These include slide projectors, PowerPoint presentations, overhead projectors, and computer projectors. Slide projectors are the oldest form of projector, and are no longer used. PowerPoint presentations are very popular and are used often. Overhead projectors are still used but are somewhat inconvenient to use. In order to use an overhead projector, a transparency must be made of whatever is being projected onto the screen. This takes time and costs money. Computer projectors are the most technologically advanced projectors. When using a computer projector, pictures and slides are easily taken right from a computer either online or from a saved file and are blown up and shown on a large screen. Though computer projectors are technologically advanced, they are not always completely reliable because technological breakdowns are not uncommon of the computers of today.

Computer-Assisted Presentations

PowerPoint presentations can be an extremely useful visual aid, especially for longer presentations. For five to ten minute presentations, it is probably not worth the time or effort to put together a PowerPoint. For longer presentations, however, PowerPoints can be a great way to keep the audience engaged and keep the speaker on track. A potential drawback of using a PowerPoint is that it usually takes a lot of time and energy to put together. There is also the possibility of a computer malfunction, which can mess up the flow of a presentation.
