Mastering Literacy Assessment: A Deep Dive into Letrs Unit 5 Session 4 Check for Understanding

Effective literacy instruction is not a one-way transmission of knowledge; it is a dynamic cycle of teaching, assessing, and responding. At the heart of this cycle lies the critical practice of Check for Understanding (CFU), a formative assessment strategy that moves beyond simple recall to probe the depth of a student’s cognitive processing. In the Language Essentials for Teachers of Reading and Spelling (LETRS) framework, this practice is elevated to a precise, intentional art, particularly within Unit 5, which delves into advanced phonics, morphology, and the complexities of the alphabetic principle. Session 4 of this unit is dedicated entirely to honing this skill, providing educators with the tools to discern not just if a student can perform a task, but how and why they are thinking. This article explores the philosophy, techniques, and transformative power of the LETRS Unit 5 Session 4 approach to checking for understanding, equipping teachers to make every instructional minute count.

The Philosophy Behind the Probe: Why "Check for Understanding" is Non-Negotiable

Traditional quizzes or end-of-unit tests provide a summative snapshot—a final grade. Formative assessment, exemplified by the CFU, is its vital counterpart: a continuous, in-the-moment dialogue that informs instruction as it happens. In the context of advanced literacy, where students must integrate phonemic awareness, phonics patterns, morphological rules (like suffixes and roots), and etymology, surface-level correctness is dangerously misleading. A student might correctly decode a multisyllabic word using a faulty strategy, or spell a word by memorization without understanding the underlying pattern. The LETRS approach insists that we must "catch thinking in the act." This means designing probes that reveal the mental pathways a student is using. Are they applying a learned phonics rule? Are they relying on visual memory? Are they confused by an irregular pattern? The goal of Session 4 is to shift the teacher’s role from evaluator to detective, using carefully crafted questions and tasks to uncover the architecture of a student’s literacy knowledge.

Core Techniques from LETRS Unit 5 Session 4: Probing for Depth

Session 4 moves beyond generic "Do you understand?" questions. It provides a toolkit of specific, actionable probes tailored to the advanced content of Unit 5.

1. The "Explain Your Reasoning" Probe

After a student decodes a word like "photograph" or spells "decision," the follow-up is not "Good job." It is: "How did you know that?" or "What part of that word told you the /f/ sound?" This forces the student to externalize their cognitive process. A proficient student might point to the "ph" digraph for /f/ or identify the Latin root "cid" (meaning "fall, cut") and the suffix "-sion" indicating the action. A student who is struggling might say, "It just looks right," or misattribute the sound to the "o." This single question differentiates between applied knowledge and guesswork.

2. The "Change One Letter" or "Word Sorter" Task

To assess understanding of phonics patterns and morphology, present a word and ask the student to transform it. For example:

• "Here’s the word "jump." Change the /j/ sound to /h/. What’s the new word?" (Answer: "hump"). This probes understanding of initial consonant substitution.
• "Take the word "teach." Change it to mean 'a person who teaches.' What do you add and where?" (Answer: Add "-er" to make "teacher"). This assesses morphological awareness and suffix application.
• Provide a set of words with a common morpheme (e.g., "predict, dictionary, predictably") and ask, "What is the same in all these words? What does that part mean?" This directly assesses morphemic analysis skills.

3. The "Is It a Real Word?" and "Why/Why Not?" Challenge

To combat overgeneralization of phonics rules, use non-words or irregular words. After teaching the rule "Ck follows a short vowel," show the word "back" (correct) and then "bakk" or "bake". Ask: "Which one follows the rule? Why is the other one not following it?" This probes whether the student understands the rule's application and its exceptions. For morphology, ask if "happiest" or "happyest" is correct and demand an explanation involving the comparative/superlative suffix rule ("-ier" and "-iest" after a final y).

4. The "Nonsense Word" Decoding with a Purpose

While nonsense words ("blarf," "stropt") are often used for pure decoding assessment, Session 4 emphasizes using them to test specific taught patterns. After instruction on the "ough" pattern, present "through," "cough," "though," and a nonsense word like "throug". Ask: "How would you say this nonsense word based on what you know about 'ough'? What makes you unsure?" This reveals if the student recognizes the pattern’s inconsistency and can apply probability based on context clues within the word structure.

5. The "Spelling Dictation with a Twist"

Instead of a simple dictation, frame it as a challenge. Say: "I’m going to say a word that uses the suffix '-ive'. Listen carefully: 'The movie was very active.' Now, spell 'active' and tell me why the 'c' is soft (says /s/)." This combines transcription with metalinguistic explanation, ensuring the student connects the spelling to the phoneme and the morphological rule (the '-ive' suffix often follows a soft c or g).

Interpreting the Data: From Answer to Instructional Decision

The value of a CFU is nullified without skilled interpretation. LETRS Session 4 trains teachers to listen for specific error patterns:

• **Phonological Errors

• Phonological Errors: Listen for substitutions (e.g., saying "/f/" for "/th/" in "think" → "fink"), omissions (saying "poon" for "spoon"), additions (saying "black" for "back"), or reversals (saying "gril" for "girl"). These indicate gaps in phoneme awareness or phonics application, signaling a need for targeted phonemic manipulation practice or reinforced grapheme-phoneme correspondence drills focusing on the specific problematic sound or pattern.

• Orthographic Errors: Note misspellings that reflect overgeneralized rules (e.g., spelling "jumped" as "jumpt" after learning "-ed" for past tense, or "cait" for "cate" when learning silent e), incorrect letter sequences for known sounds (e.g., "fone" for "phone" when aware of /f/ but not the ph digraph), or failure to apply learned patterns (e.g., spelling "knight" as "nite" despite instruction on silent k and gh). These reveal whether spelling rules are understood conditionally or rote-memorized, guiding instruction toward rule flexibility and pattern recognition in varied contexts.

• Morphological Errors: Observe errors like "happyly" instead of "happily" (misapplying the -ly suffix rule after y), "runned" instead of "ran" (overgeneralizing regular past tense), or "unhappyer" instead of "unhappier" (incorrectly stacking affixes or misapplying comparative rules). Such errors show incomplete understanding of morpheme meaning, spelling changes, or syntactic function, indicating a need for explicit instruction on suffixing rules, base word identification, and how morphemes combine to alter meaning and part of speech.

• Semantic/Pragmatic Errors: Identify instances where a student decodes a word correctly but uses it inappropriately (e.g., defining "bark" only as a tree covering when the sentence context clearly refers to a dog's sound, or reading "lead" as /liːd/ in "The pipes are made of lead" but not grasping the meaning). These highlight a disconnect between decoding and comprehension, suggesting the student may lack vocabulary depth, contextual awareness, or the ability to integrate word knowledge with sentence-level meaning—prompting instruction focused on multiple meanings, context clues, and verbal reasoning.

The true power of these CFUs lies not in tallying correct/incorrect responses, but in diagnosing the why behind the response. A student who spells "jumped" as "jumpt" isn’t just "wrong"; they demonstrate emerging knowledge of the past tense morpheme but haven’t yet internalized the spelling convention for voiced consonants before -ed. This specific insight directs the teacher to provide contrasting examples (jumped/jumped vs. hopped/hopped), engage in sound-sorting activities for voiced/voiceless endings, and explicitly link the phonetic reality to the spelling pattern. Similarly, a student accepting "happyest" as correct reveals a morphological gap requiring direct instruction on the y → i spelling change before -est, not just more spelling practice.

Ultimately, Session 4’s approach transforms fleeting classroom checks into precise diagnostic tools. By training teachers to listen for the signature of specific misunderstandings within student responses—whether in a nonsense word attempt, a morphology challenge, or a spelling explanation—educators move beyond generic reteaching. They gain the clarity to deliver just-in-time, just-enough instruction that targets the exact cognitive hurdle preventing progress, ensuring every interaction fuels meaningful growth in literacy proficiency. This is the essence of assessment informing instruction: turning observation into insight, and insight into action.
