in groups;
(5)(B) use language clearly and appropriately;
Tasks
 Students will research the major developments in information technology since 1993 to
create a timeline of events that have occurred (approximately) within their lifetime.
 Students will select, research, and give a formal presentation regarding information
technology events that have occurred within their lifetime (1993 – present).
Accommodations for Learning Differences
Lessons must accommodate the needs of every learner. These lessons may be modified to
accommodate your students with learning differences by referring to the files found on the
Special Populations page of this website (cte.unt.edu).
Preparation
 Copy the handout sheets for the students.
 Have materials ready to go prior to the start of the lesson.
 Secure a computer lab if one is not readily accessible.
Instructional Aids
 Student outline and handouts
 Student activity handouts

Materials Needed
 Butcher paper or poster board as an option for the “It’s About Time” activity
 Map pencils/markers
 Students can provide other materials as needed
Equipment Needed
 Teacher computer
 Projector (for digital presentation)
Introduction
Learner Preparation
 No special preparation necessary for this lesson.
Lesson Introduction
 Ask students to describe what they believe technology ‘looked like’ in the years 500 AD
and earlier (they may not realize it but counting boards and abaci were the first forms of
technology).
 Ask students if they have ever heard of the Digesting Duck.
Tell them it was the first example of an automated machine.
 Students should be made aware that various forms of ‘computers’ have been in
existence and used since ancient times.
 Ask students: why do they think it is important to see where technology was in the past?
 Use the multimedia presentation to present the concepts of technology from early days
to modern day.

multimedia presentation for
teacher extension.
Have the Student Notes Outline
ready to hand out at the
beginning of class. Have students
fill in the missing blanks during
your presentation,
1. Do “It’s About Time” which
involves students making and
presenting their own
timeline.

Application
Guided Practice
The teacher will show the multimedia presentation and explain the changes made in
information technology throughout the ages and up to 1993. Point out that as new technology
is developed the lifecycle of technology shortens and advances more rapidly. This should be a
reference tool for the writing assignment in this unit.
Independent Practice
Students will perform independent research to complete the following activities.
 Create a personal timeline detailing specific IT events that have occurred within their
lifetime.
 Develop a multi-media presentation based on their personal timeline.
 Write an essay comparing and contrasting two forms of technology.
Summary
Review
 What changes have taken place in information technology over the years?
 How has information technology become more complex?
 Which decade to you feel has experienced the biggest change? Why?
Application
Informal Assessment
 Daily work on assignments to monitor progress.
Formal Assessment
 Rubrics will be used to assess both activities.

“It’s About Time”
OBJECTIVE
Students will organize and develop a personal timeline. The purpose of this activity is to classify
and explain key events related to technology in their lifetime.
PROCEDURE
You are to design a personal timeline that includes the following information:
 5 Historic events
 7 Information Technology events from 1993 to the current year
 10 personal milestones in your life
MATERIALS NEEDED:
 Poster boards or butcher paper,
 string or yarn,
 rope,
 pictures,
 computer,
 printer and
 paper.
Be as creative as possible! Use pictures to make your timeline more appealing! No markers or
handwritten information may be used. Everything must be typed, cut, and pasted. The string,
yarn or rope should be used to make the actual timeline and should be adhered to the poster
board or butcher paper.
TIME ALLOTTED:
Be ready to share your timeline with the rest of the class.

“Then and Now”
OBJECTIVE:
Students will conduct research and investigate similarities and differences between selected
forms of hardware technology by comparing past and present components.
PROCEDURE:
You are to research one or two forms of hardware technology from the past.
Compare and contrast your choice(s) with one or two current forms of hardware technology.
Answer these questions in your response:
1. How important are your selections to current computing processes?
2. Where would the state of technology be if advances had not been made in this
component?
3. How would you compare the day to day activities using the past form of technology to
that of the current form?
Summarize your findings in a 450 – 500 word typed essay.
