Lesson Plan Example

 

 

Scholar:         Nancy Nurse                         

Subject:         Electrocardiology                

Lesson Topic:      EKG Tracing                  

Student Performance Objective:

By the end of the lesson:  Given a given a list of cardiology terms, their definitions, a lecture, a pictorial handout, an EKG strip, class activity, and practice students will be able to:

  • Role play all parts of the electrocardiogram with enthusiasm
  • Label an electrocardiogram with the polarity, charge, letter, heart activity, and anatomical structure for each part of the tracing in detail from memory

How will students be evaluated and what methods will be used to measure competency?

Students will be given an EKG tracing to label the polarity, charge, letter, heart activity, and anatomical structure for each part of the EKG in detail from memory.

Materials Needed: (Video, worksheets, overhead, computer, quiz, etc.)

Overhead projector, transparency of the electrical pathway of the heart, transparency of a blank EKG tracing, room with floor space, a chair for each student, and a six inch Lead II EKG strip (Run 50, Sensitivity 2)  for each student. 

Arrange the chairs to imitate the electrical pathway of the heart.

Anticipatory Set or Mental Readiness: (Describe the introduction to the lesson you will use to get the students involved in the lesson)

Ask who can describe how "The Wave" is done at a ball game or concert then explain the class will learn how to read an EKG by practicing "The Cardiac Wave."

Instructional Components: (Include type of lesson and major concepts to be covered)
  • Lecture on the EKG tracing as defined by the polarity, charge, letter, heart activity, and anatomical part of each part of an EKG tracing
  • Display a transparency of a labeled EKG strip while conducting "The Cardiac Wave" activity according to the following instructions
    • Assign each part of the electrical pathway of the heart to a student or group of students
    • Have students sit in chairs arranged to resemble the structure of the electrical pathway of the heart
    • Explain that when students are sitting they are at rest, i.e. relaxing, and when they stand they are working, i.e. contracting
    • Explain that when students "contract" they will stand and squeeze the hand of the person next to them
    • Explain when and only when they feel the hand squeezed they will stand
    • Explain they will repeat the procedure by sitting when they "relax"
    • Point to students in order of cardiac events and state the activity by anatomical part of the heart and have students perform that activity (i.e. atria contract), repeat until everyone can perform without error
    • Point to students in order of cardiac events and state the charge by anatomical part of the heart (i.e. SA node negative atria contract) and have students perform that activity, repeat until everyone can perform without error
    • Point to students in order of cardiac events and state the polarity by anatomical part of the heart (i.e. SA node repolarize atria contract) and have students perform that activity, repeat until everyone can perform without error
    • Point to students in order of cardiac events and state the letter of the EKG wave (i.e. P wave atria contract) and have students perform that activity, repeat until everyone can perform without error
    • Assign a student to direct the cardiac wave, then have students rotate through all roles, including director, until all students have assumed every role while the instructor observes and offers correction as needed

Instructional Strategies for English Learners:

A pictorial handout will spell the term in English and phonetically followed by the definition and a picture of the definition.  During the activity labeling the EKG strip,  English learners will be paired with native English speakers for guided practice.  During assessment check spelling and provide additional time to practice spelling.  During closure pay special attention to English learners pronunciation.  Set aside private time to repeat accurate pronunciation and allow English learners to practice repeating correct pronunciation.

Check for Understanding and/or Guided Practice and Independent Practice:

Give each student a six inch Lead II EKG strip (Run 50, Sensitivity 2) to practice labeling the polarity, charge, letter, heart activity, and anatomical structure for each part of the EKG in detail until he or she can do so from memory (provide additional practice strips as needed).

Closure: ("Are there any questions?" is NOT an adequate closure)

Use open ended questions to review the polarity, charge, letter, heart activity, and anatomical structure for each part of an EKG tracing. 

Assessment Tool: (Written test, skill performance, scenario, portfolio, discussion, etc.)

Label the EKG tracing provided below with the polarity, charge, letter, heart activity, and anatomical structure for each part of the EKG in detail from memory.
