The document provides an autobiographical timeline of the author's experiences with educational technology from kindergarten through college and his vision for how technology could be used in the classroom. It describes some of the early technologies the author encountered like coloring books, typewriters, and early computers. It also outlines a modeling software called STELLA that could be used to simulate natural systems and discusses using one laptop per student as a vision for the future classroom. The author believes the challenge is engaging students with technology and that learning requires effort from both teachers and students.

1. Technology and Me A personal timeline of educational technology

2. Overview Jim Tiles Started school in 1949 in Mrs. Freeman’s Kindergarten class, N.D. Fratt Elementary School, Racine Wisconsin Graduated from Washington Park High School, Racine Wisconsin in 1962 B.A. Carleton College, Northfield, Minn., 1966; Second B.A. Bristol University, U.K 1968 When I retire from teaching at Mânoa, I’d like to be qualified to teach secondary mathematics.

3. My definition of educational technology Technology in general is an intelligent use of material means to achieve a well-understood objective. Educational technology is differentiated by the goal of improving the skills or understanding of one or more human beings.

5. Kindergarten technology I filled numerous coloring books—sales samples given to me by my uncle, who was a traveling salesman for a the large local printing firm. (See next slide.)

6. High school technology A major industry in my hometown was a large printing works. In seventh grade I learned to set type from a font using a composing stick like this.

7. College technology I typed all my papers on a Smith Corona Galaxy like this (only tan, not blue).

8. A vivid technology learning experience I must have unconsciously yearned for a word- processor from the time I learned to type. My first (model on the right) and second (model on the left) computers were Apricots — not Apples!— because I was living in the UK at the time. Without my Apricot I would never have finished my second book. 1985-1990 R.I.P.

9. A technology I want to use in my classroom STELLA® is a software package that allows one to assemble compound functions using a graphics tool  Set parameters   Generate tables and graphs  This is a simple predator-prey model.

10. With STELLA® one can experiment to study the effects different parameters have on the system Introducing a hungry species can lead to collapse of its food supply followed by its extinction in that environment. If the species does not tax food resources too much, its population may establish a cyclic balance with the species and its food supply rising and falling in turns.

11. Models of natural environmental phenomena One Can Build With STELLA® Infectious Disease Dynamics Predator-Prey Systems Surface Water Contamination Matter Cycling in Ecosystems Global Energy Balance Mobile Source Air Pollution Inventories Atmospheric Pollution Transport This is a sophisticated energy-balance model, which allows one to study the effects of various levels of CO 2 in the atmosphere.

12. My vision of the classroom of the future Nothing fancy Just one laptop per child.

13. A challenge for teaching The challenge to any use of technology, whether it be the sand table or the world wide web, is to engage the students. Our motto will always have to be equos ad aquem ducimus.

14. Words of wisdom It is a delusion to think that a good teacher can convey everything that is worth knowing without disciplined effort being made by those who are supposed to learn it.
