IV. Teaching Strategies
Teacher’s Activity Students’ Activity
A. Preparation
-Good afternoon class. - Good afternoon, sir.
- (Checking of attendance) - (Students answer)
-Kindly say present if your name is called -Yes sir
B. Recall
-In sanctioning our lesson with recent technology; - all right sir
class reflect some advantage of modern technology
-Then make a group with your classmates - (Forming their group)
-After that perform a brainstorming - (Sharing their ideas)
C. Motivation
-From group-one, give an insight of the recent - Technology as of now is
technology booming industry; which
compose primarily in an
electronic device for any
reasons that beyond the
capacity of our layman’s
intellects.
- Excellent!!!
-But because of our lessons, some of these
principles can we understood through studying
the theories behind it.
-Our lesson for today is about amplification of
voltage, current and even the smallest signals.
D. Presentation
-Transistor is the basic electronic device use
as amplifier. Transistor was compose of a PNP of NPN
junctions that can multiply the signal.
-Does any one of you, is aware of the parts of the -Sir; I am!
transistors?
-Then name the three parts of the transistors -Emitter, base and collector
-How about the microelectronic devices; does anyone -Microelectronic devices is
in this class can define it? an electronic device which
have a size in millimeters.
-I want, another hands please; What about the -micro-capacitor,
examples of microelectronic devices? micro-transistors, etc…
-I.C. also a kind of microelectronic device but
it defers only in the size, because some of I.C.s’
are bigger in size.
E. Lesson Proper
- (Divide the class into groups and do
writing the procedures of the activity)
-(Assign students to be the organizer and
follow the procedure)
-All right class, execute the amplifiers’ circuit - certainly sir!
in the breadboard.
-Here are the procedures: -Students will copying and
analyzing the procedures
1. Get your laboratory kit
2. Plug-in your power supply
3. Prepare your breadboard and small cable wires
4. Construct the transistorized amplifier
5. Measure the voltage and current output
6. Construct an operational amplifier using I.C.
7. Measure the input and output signal using oscilloscope
8. Calculate the amplifier’s gain of a transistor
9. Calculate the amplifier’s gain of an integrated circuit
10. Called your teacher for the checking of the circuit connection
11. After that, pass your paper works to your teacher
V. Recapitulation
-During the course of your laboratory -The most efficient amplifier circuit
experiments; what is most efficient in is the integrated circuit
amplifications? amplifier.
-Why I.C is the most efficient compare -Because I.C. compose of
to the transistorize amplifier complex circuitry and have a
thousand of transistor inside
the component it self!
-Nice explanation!
-What is the difference of the input signal -The input signal is very small
to the output signal in as seen in oscilloscope while the output signal is
very high because this signal
is the amplified input signal.
-Good
VI. Application
The group of the students started their laboratory. They construct their amplifier circuits and begin to measure the voltage and current gain. They had also measure the input and output signals and computed the amplifier’s gain of the circuit.
Some of the student started in troubleshooting their works because of the improper connections of the circuit wiring.
These applications can increase the students’ analytical and critical thinking and doing an electronic works and circuitry.
VII. Evaluation
Criteria Score
Accuracy 20%
Speed 20%
Mastery 20%
Safeties 20%
Attendance 10%
Participation 10%
TOTAL 100%
VIII. Laboratory Rules and Regulations
-Keep the surroundings clean
-Follow the 5S philosophy in laboratory
-Leave any kinds of conductive materials (e.g. airings, bracelet, watches, etc...)
-Follow the safety procedures
-No horse playing inside laboratory premises
-Always ask for assistance
-Always ask questions when in drought
