 LESSON PLAN

Class: DPP

Class Size: 40

Time: 1 hour

Subject: Physics

Learning Area: 5.0 Electronics

Title: Electronics

Content Standards: 5.2 Semiconductor Diode

Curriculum Objective (Learning Standards):

5.2.1     Describe the function of semiconductor Diode

5.2.2     Communicate about the function of semiconductor diode and capacitor as a rectifier

Prerequisite knowledge:

1. Electric charge – negative and positive.

Prior knowledge/ Misconception/Learning Difficulties:

1. Students are aware of the attraction and repulsion of negative and positive charges.
2. Students are aware that current moves from positive to negative terminal and electron moves from negative to positive terminal.
3. Confusion between terminal of semiconductor diode.
4. Confusion between the movement of electrons and holes for forward and reverse biased.

 

Instructional Goal:

 At the end of the lesson, students are able to describe the function of a semiconductor diode and explain the function of a semiconductor diode and capacitor as a rectifier.

Instructional Objectives:

Students should be able to:

●      State the function of semiconductor diodes as an electronic component that allow the current flow in one way.

●      Explain the function of a semiconductor diode and capacitor as a rectifier.

●      Draw the half-wave and full-wave rectification circuits.

●      Determine the output graph of half-wave and full-wave rectification.

Teaching and learning approaches:

Inquiry-based learning, small group activity
