Detailed Lesson Plan In

Detailed Lesson Plan in (TLE) Computer Hardware Servicing I. OBJECTIVES At the end of the lesson the students will be able to: 1.Identify Computer Hazards and Risks. 2.Assess health and safety when working with computers. 3.Appreciate health and safety measures when working. II. SUBJECT MATTER HAZARD IDENTIFICATION, RISK MANAGEMENT, AND RISK CONTROL Reference: Technology and Livelihood Education (Computer Hardware Servicing) Page: 68-74 Materials: PowerPoint presentation (lesson content, video, images), Handouts, Visual aids and picture (optional) Level: Grades 7 to 8 Estimated Time: 20 minutes III. PROCEDURE A. LEARNING ACTIVITY TEACHER’S ACTIVITY A. Initiatory Activities 1. Daily Routine 1.1. Opening Prayer 1.2. Customary Greetings Before taking your seats, pick up the scattered papers under your chairs and be sure that your chairs are properly aligned.

STUDENT’S ACTIVITY (A volunteer will lead a prayer)

(Students arrange their chairs.) Thank you ma’am.

You may now take your seats. 1.3. Attendance Monitoring Who is absent, attendance officer?

Nobody, ma’am.

Very good.

2. Review: 5 Minutes TEACHER’S ACTIVITY

STUDENT’S ACTIVITY

 Ok class, let’s review what we discussed yesterday.

 who can tell what we discussed yesterday?

Our lesson yesterday is all about preparing and interpreting technical drawing.

 Now, what is drawing?

The art of representing any object by means of lines and shades.

 Very good.  Now what is Flowchart?

A diagram that uses graphic symbols to depict the nature and flow of the steps in a process.

 And the other name or term is called “Flow Diagram”  What are the Elements of a Flowchart The elements are Terminator, Processes, Sub – Processes, Decision, Connection, and Arrow Lines.  Ok Very good.  To develop understanding of how a process is done.  So when you should use Flowchart?  To document a process.  When planning a project.  Ok Very good.  Who can enumerate the Basic Oval, Box, Triangle, Diamond, and Circle. symbols of a flowchart? (Define Meaning)  How about the 2 types of Flowchart? Linear and Deployment Flowchart  Very good. 3. Motivation  Ok class before we move on to our next topic, you’re going to think of a possible situation on that will happen on this picture.  (Display first slide) ok what’s the possible situation to happen if you’re going to see this (display the cables running on the floor.)  Ok next, (Display third slide, cable routing). Ok what’s the possible situation to happen if you’re going to see this?  Ok last, (display third slide, loaded outlet). Ok what’s the possible situation to happen if you’re going to see this?  Ok class, what did you noticed. Observed during this activity.

(Someone will trip, falls or hurt)

(Error in connection to router, system unit, speakers, power supply. Etc.)

(Electric Shock, burn)

(we observed that when computer cables, plugs, wires are not properly connected, arranged or fixed on its place there’s always risk when neglected)

B. Developmental Activities 1. Lesson Proper: Define key vocabularies: Computer Workplace Hazards; OHS (Occupational Safety and Health)  Ok class let’s define first the word hazard (call a student to define)  Ok thank you, so hazard is anything that can you or someone.  Next, OHS (Occupational Safety and Health)  Ok thank you, so why do you think OHS is important? To identify and eliminate hazards where you working and decide how dangerous they are. 2. Discussion 1. Discuss 3 steps used to manage health and safety at work (explain and give example) a. Spot the hazard (Hazard identification) b. Assess the Risk (Risk Assessment) c. Make the changes (Risk Control) 2. Discuss common hazards encountered by computer technicians and users (explain and give examples). a. Physical hazards b. Mechanical hazards c. Chemical Hazards d. Electric Shock hazards e. CRT monitors high voltage hazards. 3. Generalization Ask about what they have learned about hazard Identification, Assessing, and Controlling risks. Ask the students, class did you understand the lesson? If yes, proceed to application if not ask if there is any question about it?

4. Evaluation A. Direction: Read carefully each statement below. Place T on the line if the statement is TRUE. Place F if the statement is FALSE.

Hazard is a situation that has the potential to harm the health and safety of people.

A planned system of working to prevent illness and injury where you work by recognizing and identifying hazards and risks.

__ 1. Health and safety procedure is the responsibility of all persons in the computer and technology industries. __ 2. Spotting the hazards means working out how likely it is that a hazard will harm someone and how serious the harm could be. __ 3. If you need temporarily run a cable across the floor, place a danger sign similar to those wet floor signs used by cleaning devices. __ 4. An LCD Monitor has a high – voltage anode inside it, which can carry a charge of up to 25, 000 volts, and it can still be holding a high charge days after the power is removed. __ 5 .
