Web-based Learning Solutions for Communities of Practice

Using Storytelling as the Pedagogical Model for Web-Based Learning
STAGE-2
B1 Problem: Why is electric current important?B1
Solution: Explain the importance of electric
current.
B1,B2 Many people die of electric shock.
B1,M2 Understand and respect electric current,
not be afraid of it.
B1,E2 Electric current is useful for running
appliances.M1 Problem: How is electric current
defined?M1 Solution: Define and exemplify
electric current.
M1,B2 Amperes = Coulombs / second.
M1,M2 It’s like watching Coulombs as water
in a river, and count how many go past in one
second.
M1,E2 Demonstrate the effect of electric
current through multimedia and multi-sensory
experience.E1 Problem: What determines electric
current strength?E1 Solution: Link to Ohm’s Law.
Explain alternating and direct current.
E1,B2 Current depends upon voltage and
resistance.
E1,M2 Ohm’s Law: I = V/R
E1,E2 Current can be direct or alternating.
The Stage-2 story is then expanded further
using the B, M, E expansion recursively. In
the Stage-3 story, only some of the story units
from Stage-2 have been expanded. The remaining
story units are left for the reader to expand
themselves.
STAGE-3
B1 Problem: Why is electric current Important?B1
Solution: Explain the importance of electric
currentB1, B2 Problem: Cause and effect of
electric shockB1, B2 Solution: Many people die
of electric shock
B1,B2,B3 Video clip of a person getting a
shock
B1,B2,M3 Explain the reason for the shock
B1,B2,E3 Ask, “So what is electric current?”B1,
M2 Problem: How should we treat electric
current?B1, M2 Solution: Understand and respect
electric current, not be afraid of it.
B1,M2,B3 (Left un-instantiated
B1,M2,M3 for the reader to
B1,M2,E3 try out some options)B1, E2 Problem:
How do we use electric current?B1, E2
Solution: Electric current is useful for running
appliances
B1,E2,B3 (Left un-instantiated
B1,E2,M3 for the reader to)
B1,E2,E3 try out some options)M1 Problem:
How is electric current defined?M1 Solution:
Define, exemplify and inject electric currentM1,
B2 Problem: What are the units of electric
current?M1, B2 Solution: Amperes = Coulombs
/ second
M1,B2,B3 (Left un-instantiated
M1,B2,M3 for the reader to
M1,B2,E3 try out some options)M1, M2
Problem: How to visualize electric currentM1,
M2 Solution: Watching Coulombs go past
M1,M2,B3 Animation of Coulombs (blobs)
going past.
M1,M2,M3 Update a counter
M1,M2,E3 Show Ampere value rises and falls
as Coulombs go past at different speeds.M1, E2
Problem: How does electric current feel?M1, E2
Solution: Demonstrate the effect of currents with
a sensory experience
M1,E2,B3 Ask the user to hold two probes
interfaced to a constant low current generator.
M1,E2,M3 Increase current through the circuit.
Display current in (mille) Amperes.
M1,E2,E3 Explain the physiological effect of
current on the body.E1 Problem: How do we calculate
electric current?E1Solution: Link to Ohm’s
Law. Explain alternating and direct current.
E1,B2 Current depends upon voltage and
resistance
E1,M2 Ohm’s Law: V = IR
E1,E2 Current can be direct or alternating.
