Conditional relationship

This page owns the teacher's role during a lesson: what share of the work of making sense of the content the teacher does by presenting it, and what share the learners do while the teacher mediates. The relationship: for learners whose goal is understanding they can use (a concept, principle, a communicative or writing skill, a value or attitude) rather than recall of delivered content, a teacher who (a) states the goal and why it matters, (b) organizes a task or materials the learners act on, (c) questions, challenges and helps contingently while they work instead of supplying answers, and (d) has learners express what they understood in their own words and carry it to a new situation, is expected to produce more engagement and more usable understanding (conceptual-understanding, near-transfer) than presenting the same content for learners to receive.

Three conditions bound it. Prior knowledge: for a novice on the target, "facilitating" that leaves the essential content to be discovered does worse than explicit instruction, so the mediator still explains, models and gives feedback; what changes is that the explanation serves the learners' work instead of replacing it. What the teacher actually does while learners work: guidance (prompts, feedback, worked examples, teacher-led steps) is what the stronger evidence credits, not the label "facilitator". Outcome and horizon: the recorded comparisons are end-of-course exams, concept tests and reported engagement; delayed retention is not established here.

No claim in this wiki compares a mediating teacher with a content-disseminating teacher directly. Most claims the earlier page cited are theoretical arguments or a single source's assertions (q1–q2, one study each, no effect size): MLE theory, Piaget, Mead, social constructionism in composition, constructivist reform in China, and a second-language acquisition argument that grammar knowledge cannot be directly taught. The nearest tested comparisons are neighbouring ones: active-learning courses against lecture in undergraduate STEM, teacher-led against student-led inquiry in school science, contingent against fixed support in one-to-one tutoring, and unassisted against explicit or guided discovery. One historical case runs the other way (a constructivist mathematics reform in Taiwan was stopped after its students underperformed). So the default below is a labelled proposal built from the earlier guidance.

How the converted siblings sit beside this: Active Learning owns what learners are asked to do with the content and its course-level evidence; Direct Instruction owns explicit explanation, modelling and the comparison with discovery, which this page's mediator still uses for novices; Scaffolding and Fading owns how help is raised, lowered and withdrawn; Inquiry-Based Learning owns investigation around a question. This page adds the teacher's side of those designs: which moves the teacher keeps, which pass to the learners, and how that division shifts across a unit. It does not repeat their models.

Default design, while the relationship is untested

The earlier page and the six pages folded into it, kept as a concrete default. Each step is a design proposal with its evidence status beside it. Minutes assume a 50-minute session and are untested proposals; scale them to the time available.

  1. Open with the goal and why it matters (about 5 minutes). Arouse curiosity with a material, object or question, then state the learning goal and what it is for, and check that learners can say it back. Untested proposal; from MLE's intentionality and meaning (the five-stage MLE lesson opens this way).
  2. For learners new to the target, explain or model it briefly first (up to 10 minutes). Do not leave the essential idea or procedure to be discovered: show it, with one worked example, then hand the task over. Minimal guidance is less effective for novices than explicit instruction [~S]; Unassisted discovery produces less learning than explicit instruction, while discovery enhanced with guidance outperforms other instruction [~S]. Skip or shorten for learners who can already begin the task.
  3. Give learners something to act on (about 20 minutes). A structured task, problem, text, materials or a communicative situation with a clear product, introduced simply and, for young children, one variable at a time. The teacher stays responsible for structure, order and progress; "facilitator" does not mean letting learners do whatever they choose. Untested proposal; from the Piaget handbook and the constructivist-classroom page folded in here. The argument that a method of thought must be gained through the learner's own abstractions is theoretical (Mead holds that a method of thought cannot be transferred but must be gained through the learner's own abstractions [+W]).
  4. Mediate while they work: question, challenge, help contingently. Circulate; ask "why" and "how" questions, offer a counter-suggestion when an answer is unexamined, and when a learner is stuck give the least help that lets them continue (a question, then a hint, then a demonstration of the step), less after a success. Hold back the answer: wait for the learner's next move before supplying it. Note how explicit the help had to be before the learner could go on: two learners with the same score can need very different levels of help, and a learner who corrects their own error after a less explicit prompt is further along (Learners placed at the same CEFR level differ in their ZPDs, which a non-dynamic test does not capture [+W]; Sarah needed less explicit help than Dena [+W]; two adult L2 learners in online chat, one case study). Spread visits by need, not by which groups invite them: in one study of collaborative science inquiry, teachers' guidance went to groups they saw as willing to collaborate, not to groups by outcome level or prior competence (Teacher guidance distribution tracked perceived willingness to collaborate [~W]). Contingent help: Contingent scaffolding improves learning more than fixed or absent support. [+S] (one-to-one tutoring, mostly; its table counts 20 distinct studies); questioning and holding back the answer as the teacher's role are untested proposals from the earlier page (MLE critical questions, Piagetian counter-suggestion, studio faculty who "had to work against always jumping in to provide the right answer").
  5. Have learners express and check their understanding (about 10 minutes). Learners summarize in their own words, pose a critical question, or explain to a partner; in pairs or groups they take turns as explainer, evaluator and judge of each other's work against stated criteria, while the teacher acts as coach, co-worker and referee. Untested proposal; from the communicative-competence packet (teacher as coach, students moving "in and out of roles such as evaluator, judge, or instructor"), the composition paper (If writing and thinking are forms of conversation, collaborative learning is an extension of social constructionism into the composition classroom [+W]) and the constructivist-classroom page.
  6. Close with a transfer task (about 5 minutes in class, or as follow-up). Ask learners to use the idea in a situation beyond the lesson (a poster for a real issue, a new problem, their own text) and say how it connects. Untested proposal; MLE's transcendence stage. Reported engagement after one such English lesson: Students reported greater engagement, motivation and language use after MLE-mediated English lessons [+W] (7th graders, interviews, no comparison group).
  7. Ask the learners how it is going, and adapt. At the end of each week or project stage, collect two or three lines of learner feedback (what helped, where they were stuck) and change the next session's task or support accordingly. Untested proposal; from the studio-course page (a flexible course structure, instructors "proactively seeking learner feedback throughout the course").
  8. Shift the division of labour across sessions. Early sessions of a unit: the teacher explains and models each new idea (steps 1–2 take up to a third of the time) and asks most of the questions. Middle sessions: explanation shrinks to a short framing, learners run the peer-check roles in step 5 and pose some of the questions. Late sessions: learners plan or choose part of the task and the teacher acts as consultant, reviewing work at agreed check-ins. Move a group to the next stage when most learners can explain the idea in their own words and complete a changed task unaided in two consecutive sessions; move an individual back to more explanation when they cannot start a task. Untested proposal; the endpoint (teacher as "designer of teaching environment, the guider for students' learning, and the academic consultant") is from the basic-education reform page folded in here. One qualitative account fits this arc: in an online networked learning community the experienced teacher's involvement fell across the middle and end phases and concentrated on tutoring, while he took part "as a learner, on an equal basis" (Both teachers remained peripherally active and concentrated their contributions on tutoring [+W]; describes one course, does not test the fading).

When a condition is not met: if learners are novices and the class is large, keep step 2 and make step 4 a whole-class scan of answers rather than circulation; if learners are already competent, drop step 2 and move straight to the late-session division of labour.

Fitting the design to a situation

The three facts that most change the decision:

  • How much the learners already know about this target. A novice needs the teacher to explain and model before handing over the work; a learner who can already start needs the teacher as questioner and consultant. If unstated, ask: can these learners begin a representative task now, unaided?
  • What the learners must be able to do, and when it is checked. Explaining an idea, using a language in conversation, holding a value, and recalling content for an exam call for different shares of teacher presentation. If unstated, ask: what will learners do, with what aids, at what point, to show they have it?
  • How much of each learner's work the teacher can see and respond to. Mediation by questioning is contingent help, and most of that evidence is one-to-one. If unstated, ask: during the task, how many learners can the teacher reach, how often, and who else (peers, software, a checklist) can respond to a learner's work?
If the brief says… Then change… Basis
Learners are novice on the target and cannot begin a representative task Keep a short explanation and one worked example before the task; give prompts and feedback during it; do not leave the key idea to be found Minimal guidance is less effective for novices than explicit instruction [~S] (its table counts 13 distinct studies)
Learners already succeed on the first task unaided Drop the opening explanation; start at the late-session division of labour, with the teacher as consultant and questioner Minimal guidance is less effective for novices than explicit instruction [~S] (a review in it says the advantage of guidance recedes once learners have enough prior knowledge; no crossover point is given)
Learners are child in preschool to grade 3 Use concrete materials they can act on, introduce one variable at a time with ample repetition, and question rather than tell; keep the routine and the choice of activity with the teacher; model an action a step beyond what the child does alone and let them imitate it; use pretend and role play as a context where children attempt more than they do in routine tasks untested; from the Piaget handbook folded into this page. Mead's argument (method of thought cannot be transferred [+W]) is theoretical, as are the Vygotskian claims that children can imitate actions beyond their independent capabilities and profit from instruction [+W] and that in pretend play the child behaves beyond her average age and daily behaviour [+W] (one review paper restating Vygotsky, no data)
An undergraduate STEM course taught mainly by lecture Replace a large share of lecture time with tasks learners do in class with feedback on what they produce; a short lecture can stay Active learning improves exam performance [+S] (STEM undergraduates, end-of-course exams); most active-learning conditions kept a substantial lecture component [~M]
School science, and the brief asks for inquiry or discovery Keep the inquiry, but teacher-led: the teacher structures the question, prompts, monitors and leads the synthesis of findings Teacher-guided inquiry outperforms student-led [+S] (a between-study moderator, not a head-to-head trial; its table counts 5 distinct studies)
The goal is communicative use of a second language Spend most time on meaningful input and communicative tasks rather than repetitive drill; where accuracy on a grammar form counts, teach the rule explicitly and then have learners use it in tasks Drill: A 1982 bilingual-education teacher-training packet asserts, citing Krashen, that repetitive drill and grammar-focused instruction are ineffective for second language acquisition [+W] (an assertion, no data). Explicit rule: Explicit L2 grammar instruction leads to larger learning effects than implicit instruction [~S] (meta-analyses; its table counts 7 distinct studies). Input alone leaves grammar weak: Comprehensible input alone is insufficient for acquisition of high levels of grammatical proficiency [~M] (a review of immersion and communicative programmes: good listening and reading, low grammatical accuracy; its table counts 12 distinct studies); informal evidence that adults do not automatically process input to develop competence [~W] (an annotated bibliography, citing Terrell). Input over drill, as theory and narrative review: structured input alone, without explicit information, is sufficient to cause changes in learner knowledge [+W] (a review of processing-instruction studies, no effect size printed); skill develops through engaging in the target activity, not drill of isolated components [+W] (theoretical). Whether explicit-rule gains reach competence is disputed: see Evidence and qualifications
The goal is a value or attitude (value education, citizenship, ethics) Build the value into subject activities learners discuss and act on, not into separate lecture classes Lecturing on values does not transact values effectively to children [+W] (reported second-hand, no study design given)
College writing or composition Make drafts the object of peer conversation (response groups, peer criticism); the teacher acts as co-worker, resource and referee, not as lecturer on writing Collaborative learning is an extension of social constructionism into composition [+W] (theoretical argument)
A project- or studio-based course in higher education Teacher as mentor and consultant: guide the design process (brainstorm, prototype, test), meet each group at fixed check-ins, push on ideas and user needs, help obtain resources, and let groups try and sometimes fail before stepping in untested; from the studio-course page folded in here (students rated the instructor as "a mentor and a consultant more than a typical teacher" at 4.17 of 5, a survey, not a comparison)
Learners will use generative AI tools in the task Keep the teacher between the tool and the learner: check AI output, restate correct AI feedback in curriculum terms learners understand, model and require marked, verifiable AI use; budget extra teacher time Teacher mediation, institutional support and responsible use were what successful AI use depended on [+M] (review of 11 studies, Arab university English classes); AI-mediating orchestration [+W] (one teacher, 46 episodes); instructor roles shift from exclusive information source toward orchestrating and regulating AI-mediated activities [+W] (conceptual synthesis, higher education; instructors keep task design and validation of AI output); teachers as ethical supervisors of AI use [+M]; AI integration increased staff workload [~M]
online-self-paced or web-based course, teacher not present in real time Provide the task, tools and criteria up front; mediate through written questions on submitted work and scheduled feedback rather than live circulation; in a discussion forum, post as a participant and tutor at the edges rather than answer every thread, and post less as groups begin to run the discussion themselves E-teachers reported shifting toward a facilitator role online [+M] (one teacher's interview; describes the shift, does not test its effect); both teachers remained peripherally active and concentrated their contributions on tutoring [+W] (one networked learning community, content and network analysis, no comparison)
Online synchronous mediation (text chat, video call) with one learner or a pair Mediate an error with graded prompts, from implicit (highlight the place, "look again") to explicit (name the error, give the form); record the level each learner needed and start the next session one level less explicit; place learners by that record rather than by a static test level Interactionist mediation in synchronous chat revealed learners' movement toward responding to less explicit help [+W] (two adult EFL learners, with backsliding; the form was not fully internalized); learners at the same CEFR level differ in their ZPDs [+W]
Mixed mode: some learners remote, some in the room, or phone-only Same task for both groups; every learner posts their answer or product to one shared space the teacher can see; alternate the teacher's questioning between remote and room learners; phone-only learners get a task completable in short text or voice replies untested proposal
One teacher with a large class Have every learner show an answer at once (cards, mini-whiteboards, a poll), mediate the commonest misunderstanding for the whole class, then go to those still stuck; peers check each other against stated criteria untested; contingent-help evidence is one-to-one (Contingent scaffolding improves learning more than fixed or absent support. [~S], cited for its limit)
Scarce facilitator time (volunteers, a busy shift, one tutor checking in briefly) Put the mediation in the materials: a printed question card for each stage, a self-check against a worked answer, and one fixed question the facilitator always asks at a check-in ("show me how you got this") untested proposal
Single session only Run the six steps in one session (goal 5, explanation 10, task 20, expression 10, transfer 5 minutes); record what learners could explain at the end and do not claim retention untested proposal
Learners with low confidence, low literacy, special educational needs or disadvantaged backgrounds Mediate more, not less: more explicit goals, more frequent short questions and success on early items; let learners express understanding orally or by doing before writing MLE mediation is reported as beneficial despite barriers [+W] (authors' assertion, no test); the SES gap in elaborated talk appeared only in the low-mediating classroom [~M] (early childhood classrooms, association only); in the same three classrooms high teacher mediation went with more children talking, in both elaborated and restricted talk [+W] (observation, association only, no effect size), and more children who could shift between elaborated and restricted talk were in the highest-mediating teacher's classroom [+W] (same study)
Learners work in small groups while the teacher circulates (collaborative inquiry, lab or project groups) Plan the round: visit every group on a fixed rotation, keep a tally of visits, and give extra time and socio-emotional support to quiet or low-confidence groups rather than to the groups that call the teacher over Teacher guidance distribution tracked perceived willingness to collaborate, not group outcome level or prior science competence [~W] (four school science classrooms, computer-supported inquiry, network analysis, not found for every teacher; shows where help went, not what reallocating it would do)
adult learners in a work setting Ask what they already do on the job; set tasks from their own work; the teacher acts as resource and consultant, explaining only what the work shows they lack untested proposal
A product or performance for a real audience Keep the product whole and real; the teacher consults on drafts at check-ins; the audience sees the product, not the learners' working or the teacher's comments untested proposal
The brief names its own routine (a rubric, check-in, prompt or template) Keep it; change only what this model says matters: add one moment where learners explain in their own words, and hold back answers during the task untested proposal
The brief supplies its own categories, criteria or rubric Use them as the criteria for peer checking and for the teacher's questions; do not substitute new ones untested proposal
The material is private or sensitive (personal experience, values, health) Learners decide who sees what they write; the teacher mediates through questions to the whole group and private, opt-in conversation, not by reading entries untested proposal
A fixed short time budget (for example 20 minutes) Keep the goal (2), task (12), and one learner explanation (6 minutes); drop the separate transfer step and set it as a later prompt untested proposal
A whole-task performance the brief wants kept whole (a project, a conversation, a full essay) Do not split it into exercises; mediate inside it at decision points, with questions and check-ins untested proposal
Stakes are high on content coverage (a national exam, a mandated syllabus), or a large-scale reform Keep explicit explanation for content the exam requires and use mediation for practice and application; check exam-like performance before widening the change Taiwan's constructivist mathematics reform was stopped in 2003 after its students underperformed [-M] (a historical account, no statistics)
The teacher is new to facilitating Script three or four questions per stage in advance, decide when to step in (after the learner's second unsuccessful attempt), and review one session with a colleague untested; from the constructivist-classroom and studio-course pages (teachers who believed in constructivism "often did not know how to use it in practice")

Thirteen of the twenty-seven rows cite a claim as the basis for the move; two more cite one only for its limit or as theory. Of the thirteen, five rest on tested comparisons carried from neighbouring designs (explicit guidance for novices, twice; STEM active learning; school-science inquiry; explicit L2 grammar instruction); the language, value, writing, disadvantage, AI, online, synchronous-mediation and small-group rows rest on assertions, reviews of perceptions, associations or single qualitative accounts, and each says so. The rest are untested proposals.

Observation, state and explanation

What can be observed: who talks and for how long, what learners produce during the task, the help asked for and given (at what level), what learners say when asked to explain in their own words, and how they do on a changed task without help. "Has constructed the meaning", "is dependent on the teacher" and "is engaged" are inferred states. Learners producing more talk or saying they enjoy the lessons is engagement, not yet understanding.

Response Plausible explanations Observation that could change the interpretation
Learners are busy and talkative during the task but cannot explain the idea afterwards The task could be done without the idea; the key content was never made available; explanation in words is the barrier, not the idea Ask for the idea on a changed case and accept a demonstration or drawing; check whether the task's product required the idea.
Learners wait for the teacher to give the answer They are novices who cannot start; earlier lessons rewarded waiting; the goal was unclear Give a matched task with one worked example; ask a learner to say the goal; withhold the answer for one more move and see whether they continue.
Learners do well in class tasks but poorly on the course exam Tasks were not aligned to what the exam asks; the exam tests recall the tasks did not practise; gains fade by the exam Compare task items with exam items; give one exam-like item unaided at the end of a session.
A few learners dominate peer checking, others stay silent Low confidence; language level; roles not assigned Assign rotating roles; give silent learners a written or private channel; compare their written explanations with their spoken ones.
Second-language learners' accuracy on a taught form rises in exercises but not in free speech The exercise affected performance only; the form is not yet acquired; time pressure in free speech Check the form in a later unprompted task; record exposure in between. Second-language theorists argue that taught-form gains often stay at performance: form-focused input manipulation is said to affect performance, not competence [~W]; learners were sensitive to untaught syntax but not to agreement they had been taught and practised [~W].
Two learners with the same test level or score respond very differently to the same help They differ in how close they are to managing alone (a placement test records only unaided performance); one has misread the prompt; one is less confident Give both the same graded prompts, implicit first, and record the least explicit prompt after which each self-corrects and whether they can say why; repeat on a new item next session. In one online case study the learner who corrected after a less explicit prompt was read as further along (Sarah needed less explicit help than Dena [+W]).
A group keeps returning to its first explanation, however the teacher questions it The idea is held in place by the way the materials are laid out and used, not only by belief; the learners lack the idea that would replace it; the question did not reach the point of difference Change the material set-up (separate, hand out or reorder the objects) and see whether new reasoning appears. In one physics tutorial the arrangement of strips held the group's initial pattern of attention and talk, and a new pattern followed when a strip was lifted and its motion enacted (Material arrangement affords and stabilizes the initial pattern of activity; later decentralization enables new patterns [+W], one group, qualitative).

These rows are proposals, untested as diagnostics. A question that probes understanding also teaches, so record each probe.

Evidence and qualifications

Neighbouring comparisons that bear on the teacher's role (tested, but not of the role itself):

  • Active learning improves exam performance [+S]: undergraduate STEM courses; across 158 studies, exam and concept-inventory scores were 0.47 SD higher under active learning than traditional lecturing, largest in classes of 50 or fewer; in 15 studies only high-intensity active learning narrowed gaps for underrepresented and low-income students. Its table counts 5 distinct studies. It shows that changing what learners do in class changes exam results; it does not isolate the teacher's mediating moves. Qualified by Most active learning college science conditions contain a substantial lecture component [~M]: 79.5% of 88 active-learning conditions in a systematic review kept lecture, so "mediator" in practice usually includes some presenting.
  • Teacher Guided Inquiry Outperforms Student Led [+S]: in a meta-analysis of 37 studies of inquiry-based school science, studies with teacher-led activities had mean effects about .40 larger than studies with student-led ones (a between-study contrast); a synthesis of 138 studies found a positive trend for inquiry over more passive instruction. It supports the teacher as active guide inside learner work, not a teacher who steps back.
  • Contingent scaffolding improves learning more than fixed or absent support. [+S]: mostly one-to-one tutoring (fourth and fifth graders on long division, eighth graders on the circulatory system); a meta-analysis of dynamic assessment ranked explicit strategy training above scaffolding. Its table counts 20 distinct studies. It supports the questioning-and-help part of mediation; generalizing it to whole classes is not shown.

Limiting claims:

Second-language acquisition: the argument that grammar cannot be taught directly (from the VanPatten and Young-Scholten pages folded in here; one essay or review each, no effect sizes). The argument runs that the language faculty works only on input, so explicit rules, drill and correction do not change what learners actually know (Mental representation is not amenable to direct explicit instruction because UG and parsers operate only on input data [~W]; Applying skill theory to grammar conflates constructs [~W]; Instruction shows little or no effect on route of L2 acquisition [~W], reported second-hand), and that form-focused gains are performance only (Successes of form-focused manipulation of input are illusory with respect to linguistic competence [~W]; A 1999 conference paper reports, citing White (1991) and Schwartz and Gubala-Ryzak (1992), that explicit negative evidence on English adverb placement produced only superficial change in French learners [~W], reported second-hand; learners acquired untaught syntactic properties but not the agreement they had been explicitly taught and practised [~W], the authors' own processing study reported in an essay). What it recommends instead is designed input and use: Structured input alone is sufficient to cause changes in learner knowledge [+W] and skill develops through engaging in the target activity itself [+W]. The input-only position is itself disputed from the other side: a review of immersion and communicative programmes reports good comprehension but low grammatical accuracy (Comprehensible input alone is insufficient for acquisition of high levels of grammatical proficiency [~M]), and an annotated bibliography reports informal evidence that adults do not automatically process input into competence (as reported by the bibliography, citing Terrell [~W]). For this page that supports step 3's "something to act on" in a second language, but it is set against the explicit-instruction meta-analyses above, which measure performance on tests; the two disagree about what the outcome should be (test performance or unprompted use), so the L2 row keeps both and the observation table checks the form in unprompted use.

The theoretical and single-source claims the earlier page rested on (each one study, no effect size): MLE holds that unmediated experience cannot yield meaningful learning (Feuerstein argues learning through direct, unmediated experience cannot yield meaningful learning or full modifiability [+W]); Qiong Jia argues that learning is the learner's own construction from old and new knowledge (Learning is an initiative construction of meanings completed by the interaction of learners' old and new knowledge [+W]); and 7th graders interviewed after one MLE-mediated English lesson reported more enjoyment and purpose (Students reported greater engagement, motivation and language use after MLE-mediated English lessons [+W]). These state the rationale; none compares conditions.

Learners, settings and outcomes differ across these claims (STEM undergraduates, school science, one-to-one tutoring, Taiwanese mathematics, adult L2), so do not rank them by effect.

The evidence by question

Further evidence, not yet read against this model

Claims and theory pages cited by the earlier page, its folded pages or later linking that are not used above. Each was read against the model on 2026-10-19; each says what it is and why it does not change the model. (Eleven claims listed here before that reading now sit in the model: the material-arrangement, mediation-responsiveness, input-sufficiency, Vygotskian, code-shifting, guidance-distribution and online-tutoring claims.)

Theory pages, not claims (they hold the rationale for steps 3 and 4; no marker, since a theory page carries no recorded evidence of its own): - Mle Theory Human Mediator Cognitive Modifiability - Piaget Three Types Of Knowledge - Piaget Four Factors Stage Progression

Objective and learner-valued goal

The designer's objective is usually that learners can explain and use the idea unaided on a new task, by a stated point. Ask separately what the learners want from the lessons: to pass the exam, to be told clearly what is right, to use the language with real people, to have a say in what they work on. These can diverge sharply from the mediating design. Learners who value being told may read the teacher's questions as withholding, and their frustration is an observation, not resistance to learning; learners who value autonomy may disengage under heavy explanation. Record both the objective and what learners say they value, and when they diverge, say so to the learners and show how the task serves their goal.

For example, adult language learners may want to pass a grammar-heavy placement test, while the designer's objective is conversational use. A mediated communicative task serves the designer's objective; one explicit rule review followed by test-format items serves the learners'. Do both, and report them separately.

What would revise this model?

The model should weaken if comparisons of teachers using the mediating moves (questioning, holding back answers, learner explanation, transfer tasks) against teachers presenting the same content, with comparable learners and aligned unaided outcomes, show no advantage; or if the gain on reported engagement does not appear on understanding or a delayed test. If the active ingredient turns out to be what learners do, whoever prompts it (software, peers, materials), then this page's model reduces to Active Learning and the teacher's role is a matter of logistics. If explicit instruction followed by practice matches the mediating design on transfer and use, the model should say so for that domain (second-language grammar is the likeliest). Do not protect the model by calling every failure "not real facilitation" after the fact.

Reported engagement, end-of-unit understanding, exam performance, delayed retention and use outside class are separate claims. The present evidence in this wiki sets no ratio of teacher talk to learner work and no rule for when to step in.

title Educators should act as mediators and facilitators of learning rather than content disseminators
description For learners working toward understanding they can use, a teacher who states the goal, organizes a task learners act on, questions and helps contingently while they work, and has them explain and transfer what they understood is expected to yield more engagement and usable understanding than presenting the content, provided novices still get explicit guidance; no claim in the wiki tests the teacher's role directly, only neighbouring comparisons (active learning against lecture, teacher-led against student-led inquiry).
