David
Kolb Model
(Experiential Learning Theory)
◦ Concrete Experience (CE) & Abstract Conceptualization (AC)
◦ Reflective Observation (RE) & Active Experimentation (AE)
Resulting Learning Styles:

Kolb model has been challenged and
adaptations suggested:
◦ Honey & Momford postulated stages of
learning and identified learners as:
1.Activist
2.Reflector
3.Theorist
4.Pragmatist
◦ Note: These learning styles are not fixed –
rather they are adaptable by student

Gregorc & Butler & Dovakhin Models –
how the mind works
◦ postulated 2 perceptual qualities:
Concrete – Registering info thru 5 senses
Abstract – understanding ideas that can’t be
readily seen
◦ postulated 2 ordering abilities:
Sequential - organizing info in linear/logical ways
Random – organizing info in chunks – no order

Flemings VAK/VARK Model – Categorizing
how students learn
◦ Visual Learners – prefer seeing ideas (pictures,
diagrams, overheads, slides etc. work well)
◦ Auditory Learners – prefer learn by listening
(lectures, discussions, recordings, etc. work well)
◦ Kinesthetic/tactile Learners – prefer learn by
experience (physical models, 3D simulations,
laboratory exercises, etc. work well)

Learning styles are affected by:
1. Time of day
2. Sleep deprivation
3. Distractions (tablets, email, iPhones, etc.)
4. Lack of food/coffee
5. Hormones
6. Home & health problems
7. Socio-economic situations
8. Employment experience
9. How they grew up
10.Personal curiosity and drive
11.Shyness & ego protectiveness

Instructor Responsibilities
Engage the student so as to:
◦ Identify prior knowledge levels
◦ Observe learning styles
◦ Modify presentation style as appropriate
Deliver content effectively
Facilitate comprehension – use tools
How it works
Why it works
Retention – on the job or credential tests
Proof of Success – quizzes & final

Student Engagement
Effective Content Delivery
◦ Instructor/Student Pre-preparation (email
communiques & questionnaires)
◦ In class – get names & personal histories
◦ Assess likely learning styles
◦ Find out why they are sitting there
◦ Adapt your presentation styles to assure
engagement and topical comprehension
◦ Pick effective content delivery mechanisms
◦ Choose effective content delivery tools
◦ Fit instruction schedule to student’s needs

Goal: Engage Your Students for
learning
◦ Partnerships between instructor &
student and among students
◦ Match your instruction style to their
learning style
◦ Connect on a personal level (names)
◦ Don’t Entertain with PowerPoint
◦ All eyes on you & your content
◦ Teach the WHYs and the HOWs

Students learn by talking to each
other (so do adults BTW)
◦ Students trust each other more than their
instructors
◦ Students have their own argot to describe
things that sometimes aids comprehension
◦ Students appreciate instructor confidence in
the back and forth on a peer to peer level

Reach out to your student body by email
Send simple questionnaire – assess
results

Comprehension – this is obligatory
◦ Understanding the whys before the hows
◦
◦
◦
◦
◦
◦
Illustrating the theory with DIY tools
Math (with sensitivity runs) = Whys
Students explain what you just presented
Team exercises for inter-student learning
Manipulatives are an excellent and cheap tool
Demo devices are excellent learning tools
Contexturalize your content to their
lives and experience

Students learn by doing
Challenge: create a “blackboard” for every
student – erasable magnet boards work
Student designs identify where instruction
was missing or weak
Provide a re-usable device
Make the job go faster with icons
Icons get returned to the board
Inexpensive and effective
Manipulatives

Demonstration Devices
Challenge 1: make a realistic portable SHW
teaching platform that teaches the WHYs
Challenge 2: Make it constructible so students
Challenge 3: Make it so it will work outside
Challenge 4: Make it see-through
can put it together & then watch what happens & diagnose
& fix:
◦ Leaks, entrained air & cavitation
◦ Siphon actions
and get HOT so students can see:
◦ Flow rates & temperature deltas
◦ Pump pressure patterns
◦ Drainback flow regimes
◦ HX characteristics

Professional, but fun – Consider team teaching
Get there early & fully prepared
Reach out to students individually early and often
NO DEATH BY POWER POINT
Escape the lecturn – rearrange the chairs
Ask them lots of questions for oral answers
Love the WhiteBoard
Teach from the Textbook
Use manipulatives & animations & videos
Bring in show & tell equipment
Frequent breaks for personal connections & Q&A
Leave time for team building and networking
Be ready for Plan B presentation
