Any thoughts?
www.monash.edu.my4
What are we doing right and what are we not?
www.monash.edu.my5
– Get the audience involved
–Jotting Impromptu ideas – Use ink to emphasize specific points
– Seamless
– Allowing handwritten presentations to be written on a large screen
– Clever use of color codes– Ease of uploading annotated slides
–Work through problems effectively

How to teach better?

• Resort to the right tools …

What is a Tablet?
www.monash.edu.my10
Are Tablets superior ?Digital Pen versus Mouse

Learning Objectives• Understand what an amplifier does• Understand where the power comes from,
and where the currents flow• Understand a simple model of the internal
behaviour of the op-amp• Understand how to use this model to
calculate the gain of a circuit with source and load resistances (impedances).
Laser pointer versus underlining - Use ink to emphasize specific points

• Isolation of one circuit and another
Singer
Guitar
Drums Left Channel
Right ChannelBass
SynthProblem: Drums signal has a sneak path through the resistor network
Jotting Impromptu ideas

Allows handwritten notations to be presented on a large screen

Seamless with a tablet – Tone Control Example
Design a circuit that amplifies low frequencies 10x more than high frequencies.

LF GLF= -R2/R1
HF GHF = - (R2llelR3) /R1 =- (R2R3) /(R2+R3)R1
-R2/R1

frequency
|Gain|
(R2R3) /(R2+R3)R1
Design Solution:Select R1, R2, R3 such that GLF=10GHF.

What about other tools like the visualizer?
• White Board – poor visibility in a big class room
• Visualizer – delay, distraction

Human Computer Interaction - High fidelity versus Low fidelity
• Low Fidelity – Presenting a model with paper and crayon
• High Fidelity – Presenting a model on the computer
www.monash.edu.my19
Outside the lecture theater
• Example - easier to annotate for example test solutions for students
• Mid Semester Test Solution s2 2010.pdf
www.monash.edu.my20
What more?
• Record your annotations together with voice ENG1030 AJL Op-amps Introduction OA1-1.mov
• Students can also write on tablets in an interactive manner
• With a wireless connection to the projector, one can move around the lecture theater or classroom
• Character recognition

Teach better with tablets
– Get the audience involved
– Jotting Impromptu ideas
– Use ink to emphasize specific points
– Seamless
– Allowing handwritten presentations to be written on a large screen
– Clever use of color codes
– Ease of uploading annotated slides
– Work through problems effectively

The flip side ….
• cost of Tablet PCs and associated infrastructure
• time spent acquiring new skills (hardly any)
• The occasional technical glitch
• lecturers have to think on their feet more than with PowerPoint

Thank you for your attention …
