Education Methodologies
The Key to Effective Teaching
By Lucille Contois
Pre-Test
 1. The statement, “ The student will explain the principle of the direct
antiglobulin test”, is an example of a (n)?
– A. Goal
– B. Objective
– C. Course description
– D. Competency
 2. Given the objective “To increase the student’s ability to perform ELISA
assays”, the error made in writing the objective is?
– A. Omitting the terminal behavior
– B. Emphasizing the teaching process
– C. Not using an action verb
– D. Not describing an observable behavior
 3. Rank the objective,” Given a patient sample for chemistry tests, the
student will separate the serum from the red cells,” by using a total of 3
general taxonomic levels.
 4. The objective,”the student will protect the Confidentiality of a patient’s
lab results” would be classified in which domain?
Pre-Test cont’d
 5. Objectives, learning activities, and test; is anything
missing from this instructional unit? If yes, what?
 6. Which of the following evaluation tools would be most
effective in evaluating a student’s “psychomotor skills”?
–
–
–
–
A.
B.
C.
D.
Anecdotal records
Checklists
Critical incident techniques
Objective tests
 7. For the objective “Defend the practice of wearing latex
gloves for phlebotomy procedures (consider isolation
policies, infection control principles and blood collection
procedures); Is the following test question
appropriate?______
– True or False? HIV can be acquired through openings in the skin
(chapped hands, sores) when exposed to contaminated blood?
Workshop Objectives
 Write correctly a variety of behavioral objectives
in all three educational domains.
 Rank objectives according to taxonomic level.
 Evaluate objectives as to their appropriateness and
clarity.
 Identify and describe key components in an
instructional unit.
 Correlate objectives with evaluation
methods/items.
 Defend the need for objectives, instructional
methods, learning activities and evaluation
methods to be inter-related.
Why?????
 NAACLS Essentials – Refer to your
notebook for actual excerpts from some of
the standards.
 Careers demand we stay current; staffing is
lean; must learn and teach others efficiently!

Goals vs. Competencies
 Description:
– General/broad
statements of purpose:
usually not stated in
behavioral terms.
 Example:
– The student will
become familiar with
the various cell
organelles
Description:
An acquired capability
stated in terms of a
composite behavior.
Example:
The student will perform
routine procedures,
employing common
techniques in the major
areas of anatomic
pathology.
A Model for Systematic
Instruction
An Instructional Unit Must
Answer These Questions…..
 Where am I?
 Where am I going?
 How am I going to get there?
 How do I know that I have arrived?
An Instructional Unit
 Pre-Test/Prerequisites
 Goals
 Objectives
 Learning Activities
 Evaluation
Effective Habits
Knowledge
Skills
Desire
Domains of Objectives
Cognitive
Psychomotor
Affective
Domains
 Cognitive
 Considerable Cognition
 Affective
 Considerable Feeling
 Psychomotor  Considerable Motor Activity
Rationale for Using Objectives
(For Student)
 Breaks topic into small manageable pieces.
 Provides guidelines.
 Easier to identify where the problems are.
 Students can evaluate own progress.
 Test time is less threatening.
(For Teacher)
 Help to focus on main topic.
 Easier to identify who is having problems.
 Easier to give feedback to students on areas
of difficulty.
 Help make tests.
 Help to set prerequisites.
 Help evaluate teaching effectiveness.
 Can review them from other courses to
better design or revise curriculum.

(Objectives Continued….)
 Terminal Behavior (Action Verb)
– Examples: List, perform, justify, illustrate,
calculate, etc.
 Conditions or Givens
– Examples: Without reference, open book, given
equipment and supplies, etc.
 Standards or Criteria
– Examples: Accurately, according to established
procedure, within 95% confidence limits,
within 10% of predetermined result, etc.
Taxonomic Levels
(Each Domain has Hierarchy of Objectives)
 Each Domain has a progressive hierarchy of
learning categories from simple to complex
behaviors.
– Cognitive has 6 levels - page 14
– Psychomotor has 7 levels - page 17
– Affective has 5 levels - page 20
Revised Levels of Cognitive
Domain
 Level 1 - Recall or Knowledge
 Level 2 - Interpretive Skills/Application
 Level 3 - Problem Solving/Analysis
Examples of Cognitive Objectives
 Without reference, the student will define
the following terms correctly:…..
 Given a quality control chart, the student
will correctly interpret the status of the
control value.
 Without reference, the student will justify
the use or application of RDW, according to
established practice.
Revised Levels of Psychomotor
Domain
 Level 1 - Perception/Set
 Level 2 – Guided Response-
Mechanism-Complex Overt Response
 Level 3 - Adaptation/Organization
Examples of Psychomotor
Objectives
 Given the procedure and necessary supplies
etc, the student will prepare a blood smear
that meets the following criteria:
–
–
–
–
Fill majority of slide
No ridges, waves, holes etc.
Has a feathered edge
etc
(Examples Continued…)
 Given the following types of micro-
organisms….., the student will demonstrate
proper specimen collection, handling and
processing procedures, according to
established protocol.
 Given the necessary materials, the student
will develop an effective staffing plan for
weekend and midnight shifts without leaving
day shift short staffed.
Revised Levels of Affective
Domain
 Level 1 – Receiving/Responding
 Level 2 – Valuing
 Level 3 – Organization/Internalization
Examples of Affective Domain
 The student will comply with established safety
procedures in the specimen processing area.
 Given the professional code of ethics for laboratory
personnel, the student will defend the need for
demonstrating respect for others according to
conventional wisdom.
 The student will judge the relevancy of cleaning
and re-stocking practices for each department to
meet established safety standards and increase
efficiency.
Group Project on Objectives
 Pick a Topic
 Write a Goal Statement
 Write Objectives
– 2 cognitive (level 2 & 3)

– 2 affective (any 2 levels)
 Critique one another
 Return and Fix
 Present

Subjective-Type of Tests
Anecdotal and Critical Incident
 Anecdotal records the description of
observed behavior
 Critical Incident is similar but stresses only
critical points
 Advantages: Easy to develop form;
economic; precise feedback to students;
look at total behavior
 Disadvantages: Subjective; lack of
standardization; difficulty in scoring; time
consuming; limited application
Checklists and Rating Scales
 Checklists use a
prepared list of
performances that are
checked to indicate the
action or quality
 Rating scales use a set
of defined traits upon
which students are
judged
 MOST COMMON
Effects to Avoid if Possible
(Rating Scale Errors)
 Halo Effect
 Error of Personal Bias
 Contrast Error
 Proximity Error
 Rater’s Mood, Memory Error etc.
