Learning Hierarchy Task Analysis

Description

Behavioral science attributes almost all learning failure to either a lack of prerequisite skills or poorly designed instructional sequencing — not to a lack of general ability, aptitude, or intelligence. The idea of breaking a complex behavior into smaller component behaviors originates with Skinner's (1954) shaping research; Gagné (1970) demonstrated its importance for classroom learning specifically.

Task analysis is the process of analyzing the internal conditions (prerequisite skills) necessary for a target performance. Its output is a learning hierarchy: an arrangement of prerequisite skills from most foundational to most complex. The process starts by identifying the task learners should be able to perform at the end of a lesson or unit, then asking, "In order to perform this task, what prerequisite skills must my learners already have mastered?" — repeating that question recursively for each identified prerequisite until the hierarchy bottoms out at genuinely foundational skills. If the logical questioning process is difficult to apply directly, an alternative is to perform the task oneself (or observe someone else performing it) and write down each step actually used; some published curricula also provide a ready-made task analysis.

Sequencing the resulting hierarchy correctly matters as much as identifying it: teaching subtraction-with-regrouping before place value, for instance, guarantees errors regardless of how well each individual skill is taught. Published curricula are not guaranteed to sequence skills well (Englemann, 1991), so it is worth examining and, if necessary, adjusting a curriculum's built-in sequence. Complex tasks — solving multi-step math problems, writing compositions, interpreting difficult text — all require learners to perform their prerequisite skills automatically and effortlessly (Mayer, 1987); learners who cannot perform prerequisites with minimal errors find it difficult to transfer new learning to unfamiliar contexts, making prerequisite mastery one of the key ingredients for transfer.

Design Implications

Context

Requirements

  • A clearly specified target task or performance to work backward from
  • Willingness to verify prerequisite mastery before introducing a dependent skill, rather than assuming it based on grade level or curriculum sequence alone

Constraints

  • An incorrectly sequenced hierarchy produces errors, frustration, and inefficiency even when every individual skill is taught well
  • Published curriculum sequences should not be assumed correct without inspection

Target Learners

  • Learners struggling with a complex skill, where the actual bottleneck is often an unmastered prerequisite rather than a deficit in the target skill itself

Target Learning Goals

  • Reliable acquisition of complex, multi-step skills by ensuring every prerequisite is mastered and correctly sequenced beforehand

Instructions

  1. Identify the target task learners should be able to perform at the end of the lesson or unit.
  2. Ask what prerequisite skills must already be mastered to perform that task; identify the most complex, highest-level prerequisites first.
  3. For each identified prerequisite, repeat the question to find its own prerequisites, continuing until reaching genuinely foundational skills.
  4. Arrange the resulting skills into a sequenced learning hierarchy, checking that no skill is scheduled before its own prerequisites.
  5. Before teaching the target task, verify learners have mastered the hierarchy's prerequisites — treat an unexpected difficulty with the target task as a cue to check for a missing prerequisite rather than assuming a lack of ability.
  • Task Analysis — a narrower application of task analysis focused specifically on breaking down a writing assignment for struggling writers; this strategy addresses the more general prerequisite-sequencing process behind any complex skill

Examples

  • A teacher whose student cannot master long division asks whether the student has learned to subtract; if not, whether they can regroup; if not, whether they can identify which of two numbers is larger — tracing the difficulty back to its actual prerequisite gap rather than concluding the student lacks mathematical ability.
