Teaching and Learning Colloquium # 2

KDU University College

Prepared by: Vineetha K Menon 29th July 2011

www.monash.edu.my3

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?

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

Seamless with a tablet – Tone Control Example

Design a circuit that amplifies low frequencies 10x more than high frequencies.

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

-R2/R1

|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

www.monash.edu.my24

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 …
