Passion matters

(Passion & B+) > (A+)

It will rain … what will your attitude be?

Our goal, yours and mine …

Reference call, interview, life

1. Useful skills

2. Ability to learn and focus

3. Attitude & enthusiasm

4. Ability to work with others

Why am I here?

Everyone is different

I learned a lot

Teacher couldn’t teach

“… learning, critical thinking, creativity, and invention – all those mind expanding skills – are all up to you. You don’t get taught; you have to learn. We tend to look at the teacher/learner relationship the wrong way round: it’s not that the teacher teaches; it’s that the student learns. The learning is always up to you” Hunt, p. 3

Flipped classroom

Everyone’s differentOne-on-one mentoring is best way to learnFlipped classroom is best we can do …

Why did I have to learn this %@#! ?

Why would I ever want to learn to program …

… in a GIS Certificate program ?!

1. Better chance of getting a job2. More useful to employer 3. More $4. Better understanding of GIS software

1. Better chance of getting a job

GIS Career Roulette

You bet $30,000 ($10k certificate + $20k opportunity cost)

You could win $500,000 ($25,000 for 20 years)

Red to win - which wheel will you play?

GIS jobs Programming an asset or required

2. More useful to employer; 3. More $

I can’t code, so this will takeme more than 15 weeks.

I can code, so this will takeme ~30 min.

2. More useful to employer; 3. More $

Add custom menus, toolbars, menu items, buttons, and tools to ArcGIS

Customize a Web mapping application to perform on-line geoprocessing

Create a stand-alone, custom GIS

Get a job with ESRI and help build ArcGIS

… that must create a sustainable future.

“The significant problems we have cannot be solved at the same level of thinking with which we created them.” - Albert Einstein

GIS is part of the solution

“Our world is changing, presenting many challenges. GIS professionals, working together, will author and share the knowledge that will make a difference. I strongly believe that this collaboration will help us bring peace and prosperity as well as a more sustainable world.”

Jack Dangermond, ESRI President
