WHAT ARE DIFFERENCES BETWEEN COMPUTER

TOOLS AND TRADITION TOOLS FOR INSTRUCTION?

COMPUTER TOOLS

- Help teachers plan, implement, and evaluate instruction

- Help students during their learning

TRADITIONAL TOOLS

- Teacher planed and implemented instruction using typewriters, pencil, and paper.

TEACHER

ASSISTANT

LEARNER

• Using computer to present instruction directly to

students

• Providing instructional activities, situation, or

quizzes

• Evaluating learners’ responses and determining

appropriate follow up activities.

• Using the tools to “teach” the computer to

perform some task

• Helping teacher and learner in performing routine

work tasks

• Helping teacher in planning and managing

instruction

• Aiding students in organizing and presenting

their work.

GRAPHICS TOOLS

AND

DESKTOP PUBLISHER

Page 14: Chapter 3 Computer tools for teaching and learning

There are 2 basic types: Bitmapped, Vector

Bitmapped (or raster): each pixel directly maps, or corresponds to, a

portion of the image. The computer must keep track of position

and color information for each pixel. #become jagged looking

when scaled to larger size

Vector (or draw): the computer “remember” the steps involved in

drawing a particular graphic image. This information is

independent of a particular screen location or a graphic’s size.

#vector can be scaled without any loss of quality.

Page 15: Chapter 3 Computer tools for teaching and learning

FEATURES OF GRAPHICS TOOLS

Creative Arts : permit you to produce original

artwork or modify existing artwork. There

are variety of stimulate tools intended to

mimic what an artist use (pencil,

paintbrush, color palette, eraser etc.).

You can select and control colors, and fill

shapes with colors and/or patterns, and

let you apply special effects (blurring,

textures, and the illusion of embossing).

Packages e.g.: Adobe Photoshop, Adobe

illustrator, Corel draw, Painter etc.

Page 16: Chapter 3 Computer tools for teaching and learning

Business and scientific graphics : a

program accept data, from within the

program or from another source

(spread sheet – Microsoft excel), and

produce a chart or a graph .

Business graphics include bar chart,

pie chart, line graph etc. Scientific

focus on line graphs as well as

trigonometric and other

mathematical functions.

Packages e.g.: Cricket graph, graphical

analysis, Microsoft graph etc.

Page 17: Chapter 3 Computer tools for teaching and learning

Mechanical Drawing : computer-

aided design (CAD) is used for

the production of blueprints and

factory floor layouts, for

landscape architecture, for the

design of machined parts, and

so on

Packages e.g.:

AutoCAD, PowerCADD, IntelliCAD

Page 18: Chapter 3 Computer tools for teaching and learning

Print graphics : inexpensive

program that use built-in clip

art to produce simple

printed work such as

signs, banners, and greeting

cards etc.

Packages e.g.:

PrintMaster, PrintShop

Page 19: Chapter 3 Computer tools for teaching and learning

Desktop Publishing : response to

demand for control over both text

and graphics on a printed page.

It gives users a high degree of

control over the composition and

layout of materials on printed

page. Desktop publishing

program typically afford greater

control and precision. This

software remains important

today both in the publishing

industry and for such

educational applications as

school newspapers.

Packages e.g.: Adobe PageMaker,

QuarkXPress, Ventura Publisher,

Publishing center etc.

EXAMPLE USES FOR TEACHER AND STUDENTS

Teacher’s Uses

Creating handouts, worksheets, and other instructional materials for student use.

Creating signs or other graphical materials for classroom display

Maintaining graphical information in a class database

Designing and producing a class newspaper to send home to parents

Student’s Uses

Making drawings for mini-books, reports, and other illustrated material

Creating a graph of data collected in the science laboratory

Producing major school works such as the school newspaper or yearbook

Page 21: Chapter 3 Computer tools for teaching and learning

PROBLEMS AND PITFALLS

Student may tend to emphasize from over substance, with page

layouts programs, students (and teacher) often spend inordinate

time fiddling with how a document looks. They may experiment

with different fonts and page layouts at length while worrying

little about the content. With graphics tools too, students often

spend much time to experimenting with various features,

TEACHERS’ USES

Supporting lectures or other presentation to groups in the classroom.

Making presentations to school boards, at professional meetings, or in other

nonschool settings. Recording the results of brainstorming or other

development activities in class.

Displaying information at events, most presentation packages support timed

or auto-run features that allow slide shows to run unattended.

Preparing notes, pictures, or other material that can be printed, transferred to

photographic slides, or converted for placement on the Web. a

Page 39: Chapter 3 Computer tools for teaching and learning

STUDENTS’ USES

Making in- class presentations or reports and preparing

textual information, pictures, or other material that can be

printed, transferred to photographic slides, or converted for

placement on the Web.

Page 40: Chapter 3 Computer tools for teaching and learning

PROBLEMS AND PITFALLS

Students may emphasize form over substance. When use

prepared templates, can make almost any content look good. First,

construct presentations using a blank template or in outline mode

to discourage them from focusing on the flashy elements of the

package. After creating the content, students then can focus on

adding visual appeal. Caution students to avoid overdoing

available effects when adding visual elements. Good design

principles still apply. Teacher who presentation software,

sometimes fall into the trap of wanting to turn everything into a

presentation. It is best to take a variety of approaches when trying

to reach different learners and help them stay actively involved.

FEATURE OF SPREADSHEETS

- Mathematical functions.

- Formatting.Text label or numbers can be aligned.

- Graphing. Most spreadsheet programs have graping capability. The program will

produce a graph of the data in the highlighted cells.

- Database elements. You can create a simple database in a portion of the

spreadsheet by treating the cells in a particular column as a database field.

Page 48: Chapter 3 Computer tools for teaching and learning

- Macros. A macro is a short cut for encoding a series of

actions in a computer program. It provide a means of

performing a number of separate steps through a single

command.

- Printing and disk storage.

- Creating a gradebook.

- Keeping other information about students.

- Tracking costs of classroom materials.

- Demonstrating complex calculations to a class.

- Financial records of a student organization.

- Setting up a personal budget.

- Analyzing data from science experiments.

Page 50: Chapter 3 Computer tools for teaching and learning

Problems and Pitfalls

- The spreadsheets is flawed formulas.

- Students may have a poor grasp of the limitations of the

limitations of the information produced by the spreadsheet

because they do not understand the underlying model or

FEATURES OF COMPUTER TELECOMMUNICATIONS

Electronic Mail (e-mail) is

the most widespread

application of computer

telecommunications. It is

analogous to postal mail

but much faster and more

versatile. E-mail allows

private messages to be

sent and received from

individuals to other

individuals or from

individuals to groups.

Page 56: Chapter 3 Computer tools for teaching and learning

INFORMATION RETRIEVAL

Information Retrieval is one

of the most important

uses of internet. A source

of vast information

resource on the Internet

is the World Wide Web

(WWW or just the Web.)

The Web consists of

millions of sites of

information displayed in

hypermedia format.

Page 57: Chapter 3 Computer tools for teaching and learning

INFORMATION PUBLISHING

Information Publishing is

being seen as a place

where organizations and

individuals can display

information for others to

view and/or retrieve.

So, many schools have

created their own

Websites, which

teachers, students, and

whole classes often use

for display of project as

well as for dissemination

of information about the

school.
