Instructional and Guided Learning Analysis Methods: Learning Hierarchy
(Prerequisites) Analysis
Dr. Lee Chwee [email protected] 67903285
What is needs assessment? Why do learner analysis? What do you want to find out when conducting job task analysis? In pairs, take about 10-15 min to do think about the purposes of task analysis? (retrieve from folder the document on TA purposes)
Recap
Such methods describes task or jobs in terms of the ways they are best learned, which may or may not correspond with the ways the jobs are performed. More on the way learners process information as they perform task.The emphasis is on what must the learner know in order to perform the task
Instructional and Guided Learning Analysis Methods
There are basically three analysis methodsLearning Hierarchy AnalysisInformation Processing AnalysisLearning Contingency Analysis
Instructional and Guided Learning Analysis Methods
When an instructional objective indicates that the learner will use a concept, apply a rule, or solve a problem, a LHA can pinpoint the prerequisite skills to perform that objective. A LHA represents content in a hierarchical fashion. A learning hierarchy depicts these prerequisites in an ordered hierarchical relationshipLower-level skills are prerequisites to the higher-level skill.
Learning Hierarchy (Prerequisites) Analysis
Prerequisite sequencing is the basis for much of the organization of curriculum, especially in mathematics. In elementary school, students learn basic arithmetic operations before teaching algebra in junior high school.
Prerequisite sequencing is most obvious in mathematics but also shows up in language classes and sciences, as well.
Learning Hierarchy (Prerequisites) Analysis
So the assumption is we must understand the basics before can move on to more difficult skills. Prerequisite Sequencing is a foundational assumption of traditional instructional design. Most designers believe that basics must be mastered before moving onto more complex skills. Prerequisites analysis IS NOT A PROCEDURAL ANALYSIS. The tendency is to fall back into procedures. With prerequisites analysis, you are analyzing SKILLS.

Learning Hierarchy (Prerequisites) Analysis
Prerequisite sequencing refers to intellectual skills. Gagne (1985): learning outcomes in the domain of intellectual skills are organized such that each depends on the mastery of simpler prerequisite skills (bottom-up sequence) see next slide

People must comprehend information before they can classify concepts. People need to understand (classify) concepts before being able to apply rules and principles, and those rules and principles are prerequisite to solving problems. That is the essence of prerequisites analysis.
Many skills either benefit from or require the acquisition of more basic skills before learning more complex skills. Prerequisites analysis is the methods for identifying that sequence
Learning Hierarchy (Prerequisites) Analysis
LimitationsMuch of the contemporary research on situated learning and everyday cognition calls into question this assumption. Can you identify the prerequisites for all learning outcomes?
Learning Hierarchy (Prerequisites) Analysis
Begins by identifying the highest level (most complex) learning outcome that is sought and develops a hierarchy of prerequisite skills for that outcome.
1. Familiarize with the topic2. State the final learning outcome3. Identify the entering capabilities the learners have in
regard to the final learning outcome4. Identify first-level prerequisites5. Identify second-level prerequisites6. Identify third-level and subsequent level
prerequisites7. Determine how far to go in breaking down the
prerequisites (how do you know?)8. Construct the learning hierarchy (see slide 15)9. Verify the learning hierarchy (logically-asking yourself
questions or approach SME) or empirically-develop test items)
Individual interviewStructured group interviewDocumentation analysis (using wide range of documents)

Can be used in the design of constructivist learning environment. The below is an example (to remove a wounded eagle from the wilderness to the veterinary)

Now that you have done the activity, tell me this LHA can be meant for who? Trainee doctor? Consultant? Who else?What are the difficulties when conducting LHA?
