The frame. Direct Instruction (DI) has an unusually large research base for a school program, including the federal Project Follow Through study. It is also one of the most-often run the wrong way. DI programs, Reading Mastery, Corrective Reading, Connecting Math Concepts, use tight scripts. They are fast. They have set steps for fixing errors. A para who knows DI and runs it the same way each time can drive big learning gains. A para who treats DI like a general reading or math task gets little.
Direct Instruction (capital letters) means the programs built by Siegfried Engelmann and his team. The core idea: if a lesson is built well, put in the right order, and said clearly, almost any student can learn almost any skill. DI programs put that idea to work.
DI is not the same as direct instruction (lowercase). Lowercase direct instruction is a general term for clear, teacher-led teaching. DI is a set program with a copyright. It has an exact lesson format. The research goes back to Project Follow Through: one of the biggest school studies in US history.
Every DI lesson is scripted, not as a suggestion, but as a requirement. The script says what you say. It says what the student should say back. It says what to do when the student gets it wrong. Stepping away from the script, even to add a story, breaks the careful order of the program.
Most DI lessons use unison (group) responding. All students answer together on a signal, not one at a time. Group responding gets more answers in each lesson. It cuts wait time. It lowers the shame of getting it wrong alone. It tells you right away if the group gets it. The signal is usually a hand drop, a clap, or a set word ("go").
The signal must be clear and the same every time. Students answer together when the signal comes, not before, not after. Pacing should be brisk. DI lessons are built to be lively and fast. Slow pacing means fewer chances to learn. It also invites off-task behavior.
DI has a set order for fixing errors that you must follow:
Do not just repeat the question. Do not praise a fixed answer the same way you praise an answer the student got on their own. The error-fixing steps are not a punishment. They are teaching. They should feel calm and matter-of-fact.
Reading Mastery is now published as Reading Mastery Transformations. You may still see the older Signature Edition in use. Either way, it is a full reading program for K-5. It covers decoding, comprehension, and language. It is often used for students with reading delays. Key parts:
Corrective Reading is for students in grades 3-12 who read below grade level. It has two strands: Decoding and Comprehension. Key parts:
Connecting Math Concepts (CMC) is a DI math program. It covers basic skills through fractions, ratios, and getting ready for algebra. Like Reading Mastery, it uses scripted lessons with group responding and set error-fixing. A para running CMC should:
DI programs usually come with fidelity checklists (running it the same way every time). The checklists cover use of the script, pacing, signal, group responding, error-fixing, and lesson length. If your school has DI coaches, you may get formal check-ins. Take these seriously. In DI, running it the same way every time has been linked to student results in research.
If there is no formal fidelity system, check yourself: after each lesson, ask: Did I follow the script? Did I use the same signal every time? Did I use the error-fixing steps every time? Did I keep the pace brisk?
A para is running Reading Mastery with a group of four students. The lesson brings in a new sound. The script says to point to the letter and say the sound. Students answer together. The para, wanting to help, adds her own words: "This letter makes the same sound as the one in 'cat.' Cats are fun!" The students smile and tune in. But the extra talk slows the pacing. It breaks the careful order. It brings in a word ("cat") that has not been taught yet in the program. The script was not random. What the para added broke it.
A para runs a Corrective Reading Decoding lesson. She follows the script word for word. She gives a clear hand-drop signal. She asks for group responding. When two students say a word wrong on the word list, she stops right away: model ("the word is 'stride'"), lead ("say 'stride' with me"), test ("your turn, everyone"), delayed test (she comes back to "stride" after three more items). The error-fixing takes 20 seconds. The lesson goes on. By the end of the week, all four students have that word down. This is what DI fidelity makes.
| Try this | Watch out for |
|---|---|
| Follow the script: including the exact words of corrections and the order of items | Adding your own words, stories, or examples to fill in the script |
| Practice your signal before the first lesson so it is clear and the same from day one | Skipping error-fixing because the student almost got it right |
| Use error-fixing every time, even for small errors; the program is built to catch and fix all errors | Using a signal that changes, which makes students answer at different times and breaks group responding |
| Keep the pace brisk: if a lesson keeps taking twice as long as it should, talk to the teacher | Letting the lesson slow down because going slow feels more kind |
Bottom line. DI is not a teaching style. It is a product with directions. The directions come from years of research and careful design. Your job is to run the product the way it was built. Watch what happens. Tell the team what you see. When DI is run the same way every time, it works very well.
How to run a Direct Instruction script with fidelity
For paraprofessionals assigned to deliver Direct Instruction programs
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 (currently published as Reading Mastery Transformations; the earlier Signature Edition is still in use in many buildings) is a comprehensive reading program for K-5 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 -- Signature Edition and earlier use a unique alphabet (modified orthography), while Transformations uses ordinary print, so check which edition you have
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 |
