Independent and Dependent Enabling Skills
Independent and Dependent Enabling Skills
Independent enabling skills
- Skills the teacher assumes students already have
- Prerequisites that are not taught in this unit
- Treated as the foundation
- Must be checked through diagnostic assessment
Dependent enabling skills
- Skills built within this unit
- Depend on independent enabling skills
- Taught in sequence within the unit
Why the distinction matters
- Without it, teachers may try to teach prerequisites within a unit (wasting time)
- Or skip prerequisites entirely (causing failure)
- The distinction guides what to diagnose and what to teach
Within the model, identifies a key distinction: enabling skills are either independent or dependent. The two kinds need different treatment by the teacher.
What enabling skills are
Enabling skills are the skills students need to reach a terminal objective. The terminal objective is what the unit aims for. The enabling skills are everything required to get there.
For a unit on argumentative essay writing, the terminal objective might be “students will write a 500-word argumentative essay defending a position with three supporting points and a conclusion”.
The enabling skills include:
- Sentence structure (writing complete sentences).
- Paragraph structure (topic sentence, supporting sentences, conclusion).
- Vocabulary appropriate to argument (words like “however”, “therefore”, “in contrast”).
- Logical reasoning (distinguishing argument from fallacy).
- Spelling and punctuation.
A student who has all of these can put them together into an argumentative essay. A student missing any of them produces a weaker essay.
The teacher’s job in task analysis is to list every enabling skill needed.
Independent enabling skills
Divides enabling skills into two categories. The first is independent enabling skills.
Independent enabling skills are skills the teacher assumes students already have. They are prerequisites for the unit. The teacher does not plan to teach them within this unit because students should arrive with them.
For the argumentative essay unit, sentence structure might be an independent enabling skill if the unit is for Class 7 or higher. By Class 7, students should already know how to write complete sentences. The unit assumes this and builds on it.
A spelling foundation is another independent enabling skill. Class 7 students should already spell common words correctly. The argumentative essay unit does not teach spelling from scratch.
The risk: if students arrive without an independent enabling skill the teacher assumed they had, the unit will fail for those students. The argumentative essay unit assumed sentence structure, but if a student cannot write a complete sentence, they cannot write a paragraph, let alone an essay.
The solution: diagnostic assessment. Before the unit begins, the teacher checks whether students have the independent enabling skills. The pre-planning stage covered this. A simple check (a sentence-writing prompt, a paragraph-reading task) tells the teacher who has the prerequisites and who does not.
Students missing prerequisites need remediation before the unit advances. This is more time consuming than just starting the unit, but it is the only way to avoid failure later.
Dependent enabling skills
The second category is dependent enabling skills.
Dependent enabling skills are skills built within the unit. They depend on independent enabling skills as their foundation, but they themselves are taught during the unit.
For the argumentative essay unit, paragraph structure might be a dependent enabling skill. Students may know how to write sentences (independent prerequisite), but they may not yet know paragraph structure. The unit teaches paragraph structure as part of its work toward the terminal objective.
Argument-specific vocabulary is another dependent enabling skill. Students may have general English vocabulary (independent), but they likely do not know argumentative connectors like “however”, “in contrast”, “moreover” in the specific context of essay writing. The unit teaches these as part of itself.
’s example from Math: in a unit on subtraction, simple subtraction facts (e.g., 7 - 3 = 4) might be an independent enabling skill (students arrive with these). But subtraction in columns with zero involved is a dependent enabling skill that the unit teaches.
The teacher’s job is to teach dependent enabling skills in the right order. Simple dependent skills come first; complex dependent skills come later. Each dependent skill builds on the previous.
A worked example: writing skills
Terminal objective: Students will write argumentative essays.
Independent enabling skills (assumed):
- Spelling common words.
- Basic punctuation.
- Writing complete sentences.
Dependent enabling skills (taught within the unit):
- Paragraph structure (topic sentence, supporting sentences, conclusion).
- Argumentative vocabulary (however, therefore, on the other hand).
- Distinguishing logical arguments from fallacies.
- Identifying a thesis statement.
- Writing a thesis statement.
- Supporting a thesis with three points.
- Concluding an argumentative essay.
The dependent skills build on the independent ones and on each other. Writing a thesis statement requires sentence-writing (independent) and paragraph structure (earlier dependent). Supporting a thesis requires writing a thesis statement (earlier dependent) plus argumentative vocabulary (earlier dependent).
A teacher who has mapped these dependencies can plan the unit lesson by lesson. Lesson 1: paragraph structure. Lesson 2: argumentative vocabulary. Lesson 3: logical arguments versus fallacies. Lesson 4: identifying thesis statements in sample essays. Lesson 5: writing your own thesis statement. And so on, building up to the full essay.
Where they are taught
Independent: assumed prerequisites; not taught within the unit.
Dependent: built within the unit; depend on independent skills as their foundation.
Independent skills must be checked through diagnostic assessment. Dependent skills are taught in sequence during the unit.
Why the distinction matters
Mistake 1: Treating dependent skills as independent. A teacher might assume students already know paragraph structure when in fact they do not. The unit on argumentative essays then fails because students cannot write paragraphs. The teacher thought paragraph structure was a prerequisite (independent) when it should have been taught within the unit (dependent).
Mistake 2: Treating independent skills as dependent. A teacher might try to teach sentence writing within an argumentative essay unit. This wastes time. Students should already know sentence writing by the time they reach this level. Trying to teach it in this unit means the unit cannot finish its real work in the available time.
The fix is to draw the line carefully. What should students arrive with? That is independent. What does the unit need to teach to reach the terminal objective? That is dependent.
The line moves with grade level and with curriculum. Sentence writing is dependent in early primary (taught in those units) but becomes independent by middle school (assumed by then). The teacher must adjust the line based on where students actually are.
How to find the line
Three questions help a teacher decide whether a skill is independent or dependent.
Question 1: Does the curriculum say this should be mastered before this grade? If yes, treat it as independent. The curriculum says students should arrive with it.
Question 2: Does diagnostic assessment confirm most students have it? If yes, treat it as independent. Most students arriving with it means the assumption holds.
Question 3: Does the terminal objective build directly on this skill? If yes, the skill is closely related to the unit’s work. Whether it is independent or dependent depends on the answers to questions 1 and 2.
A skill that the curriculum says should be mastered AND diagnostic assessment confirms students have is solidly independent. A skill that the curriculum says students should not yet have OR that diagnostic assessment shows they lack is dependent.
The teacher uses these questions for each skill in the task analysis. The result is a clean separation.
Curriculum, diagnostic assessment, terminal objective dependency
Does the curriculum say this should be mastered before this grade? (If yes, lean independent.)
Does diagnostic assessment confirm most students have it? (If yes, lean independent.)
Does the terminal objective build directly on this skill? (Reveals how closely connected it is.)
A skill the curriculum expects AND students show they have is solidly independent. A skill students show they lack is dependent regardless of curriculum.
