Direct Instruction Programs

How to run a Direct Instruction script with fidelity

| The frameDirect Instruction (DI) is one of the most researched educational interventions ever developed. It is also one of the most frequently implemented incorrectly. DI programs -- Reading Mastery, Corrective Reading, Connecting Math Concepts -- use tightly scripted lessons, rapid pacing, and specific error correction procedures. A para who understands the logic of DI and delivers it with fidelity can produce significant learning gains. A para who treats DI as a general reading or math activity without following the script produces little. |

What Direct Instruction is

Direct Instruction (capitalized) refers specifically to the programs developed by Siegfried Engelmann and colleagues, grounded in Engelmann's Theory of Instruction. The core principle: if instruction is logically designed, sequenced, and clearly communicated, virtually any student can learn virtually any skill. DI programs are the implementation of that principle.

DI is not the same as direct instruction (lowercase), which is a general term for explicit, teacher-led instruction. DI is a specific, copyrighted curriculum with a precise lesson format and a research base going back to Project Follow Through, one of the largest educational research studies in US history.

DI principles

Scripted lessons

Every DI lesson is scripted -- not as a suggestion but as a requirement. The script specifies exactly what the teacher/para says, what the expected student response is, and what to do when students respond incorrectly. Departing from the script -- even to add examples or explain more fully -- undermines the sequencing logic of the program.

Unison responding

Most DI lessons use unison (choral) responding: all students respond simultaneously on a signal rather than taking turns. Unison responding increases the number of student responses per lesson, reduces wait time, reduces individual embarrassment from errors, and gives the para immediate information about the group's understanding. The signal is typically a hand drop, a clap, or a specific word (go).

Signal and pacing

The signal must be clear and consistent. Students respond together when the signal is given -- not before, not after. Pacing should be brisk: DI lessons are designed to be engaging and fast. Slow pacing reduces the number of learning opportunities and invites off-task behavior.

Error correction in DI

DI has a specific error correction sequence that must be followed:

Stop at the error immediately

Model: say or demonstrate the correct response

Lead: have all students respond with you

Test: give the signal and have students respond independently

Delayed test: return to the item after several other items to check retention

Do not simply repeat the question. Do not praise the corrected response the same way you praise an independent correct response. The error correction sequence is not punitive -- it is instructional and should feel matter-of-fact.

Common DI programs and what paras need to know

Reading Mastery

Reading Mastery (now in its Signature Edition) is a comprehensive reading program for K-6 that includes decoding, comprehension, and language. It is often used for students with reading disabilities or significant reading delays. Key features:

Lessons are numbered; placement testing determines where students start

Early lessons focus on sound-symbol correspondence and blending using a unique alphabet (modified orthography)

Later lessons include comprehension stories with scripted questions

Pacing: lessons should take 30-45 minutes maximum

Corrective Reading

Corrective Reading is designed for students in grades 3-12 who are reading below grade level. It has two strands: Decoding and Comprehension. Key features:

Decoding strand: systematic phonics with decodable word lists and stories

Comprehension strand: explicit vocabulary and reasoning skills

Placement determines entry point based on diagnostic assessment

Error correction must be applied consistently -- the program will not work if errors are tolerated

Connecting Math Concepts

Connecting Math Concepts (CMC) is a DI math program covering foundational skills through fractions, ratios, and algebra readiness. Like Reading Mastery, it uses scripted lessons with unison responding and specific error correction. The para running CMC should:

Follow the script for numerical operations, not improvise examples

Use the chalkboard or dry-erase board as specified in the lesson

Apply the error correction sequence for every error -- do not skip it for math facts the student almost got right

Fidelity tools

DI programs typically include fidelity checklists that cover: use of the script, pacing, signal quality, unison responding, error correction application, and lesson completion. If your school has DI coaches or trainers, you may receive formal fidelity observations. Take these seriously -- DI is one of the programs where fidelity has been directly linked to student outcome in research.

If no formal fidelity system exists, self-monitor: after each lesson, ask yourself: Did I follow the script? Did I use consistent signals? Did I apply error correction every time? Did I pace the lesson briskly?

Scenarios

Scenario A: The helpful improviser

A para is running Reading Mastery with a group of four students. The lesson introduces a new sound. The script says to point to the letter and say the sound; students respond in unison. The para, wanting to help, adds her own explanation: this letter makes the same sound as the one in the word cat. Cats are fun\! The students smile and engage, but the extra talk slows the pacing, departs from the carefully designed sequence, and introduces a word (cat) that has not yet been taught in the program. The script was not arbitrary -- the explanation the para added undermined it.

Scenario B: The fidelity practitioner

A para runs a Corrective Reading Decoding lesson. She follows the script word for word, delivers a clear hand-drop signal, and requires unison responding. When two students respond incorrectly on a word list item, she stops immediately: model (the word is stride), lead (say stride with me), test (your turn -- everyone), delayed test (she returns to stride after three more items). The error correction takes 20 seconds. The lesson proceeds. By the end of the week, that word is mastered by all four students. This is what DI fidelity produces.

| Try this | Watch out for |

| Follow the script -- including the exact wording of corrections and the specific sequence of items | Adding your own explanations, examples, or stories to supplement the script |

| Practice your signal before the first lesson so it is clear and consistent from day one | Skipping error correction because the student almost got it right |

| Apply error correction every time, even for small errors -- the program is designed to catch and correct all errors | Using an inconsistent signal, which causes students to respond at different times and reduces unison responding |

| Keep the pace brisk: if a lesson regularly takes twice the allotted time, discuss with the teacher | Allowing the lesson to slow down because slow pacing feels more supportive |

| Bottom lineDI is not a style of teaching -- it is a product with instructions. The instructions are the result of decades of research and careful design. Your job is to deliver the product as designed, observe what happens, and report what you see. When DI is delivered with fidelity, it works remarkably well. |
