• Comment goes here.
Are you sure you want to
• Not sure about you, but for me, just trying to follow the laser pointer leaves me sea sick. Using ink to highlight helps students to stay better focused than using laser pointers.

## Tablet pc presentation kduPresentation Transcript

• Teaching and Learning Colloquium # 2 KDU University College Prepared by: Vineetha K Menon 29 th July 2011
• Any thoughts?
• What are we doing right and what are we not?
• 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
• Work through problems effectively
• Engagement versus class size
• Engagement versus class size
• 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
• Get the audience involved
• Jotting Impromptu ideas
• Isolation of one circuit and another
Singer Guitar Drums Left Channel Right Channel Bass Synth Problem: Drums signal has a sneak path through the resistor network
• 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. R 2 R 3 C -R 2 /R 1 LF HF frequency |Gain| (R 2 R 3 ) /(R 2 +R 3 )R 1 Design Solution: Select R 1 , R 2 , R 3 such that G LF =10G HF . Output, v o+ R 1 v 2 v 1 Gain LF G LF = -R 2 /R 1 HF G HF = - (R 2 llelR 3 ) /R 1 =- (R 2 R 3 ) /(R 2 +R 3 )R 1
• What about other tools like the visualizer?
• White Board – poor visibility in a big class room
• Visualizer – delay, distraction
• Seamless with a tablet – Tone Control Example Design a circuit that amplifies low frequencies 10x more than high frequencies. Output, v o+ v 2 R 2 v 1 Input, v in+ R 1
• 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
• Outside the lecture theater
• Example - easier to annotate for example test solutions for students
• Mid Semester Test Solution s2 2010.pdf
• 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
• Now at Monash …..
• Tablet initiatives can lead to publications Ae090155_bookinclusion.docx
• 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
