実証済み英語学習メソッド48選

"Comprehensible Input (CI)"

Listening or reading at a level just above your current ability (i+1) so you acquire language naturally.

"Watching YouTube videos with subtitles at B1 when you are A2 is classic CI."

"Language Immersion"

Surrounding yourself with English as much as possible, mimicking how children acquire their first language.

"Switching your phone and social feeds to English is a low-cost immersion strategy."

"Extensive Reading"

Reading large quantities of easy, enjoyable texts without looking up every word.

"Reading one graded reader per week at your level builds fluency faster than grammar drills."

"Narrow Reading / Listening"

Consuming many texts on the same topic so vocabulary repeats and context becomes clear.

"Spending a month reading only tech news in English rapidly builds domain vocabulary."

"Shadowing"

Speaking along with a native audio recording simultaneously to improve rhythm and pronunciation.

"Shadowing a podcast episode for 15 minutes a day noticeably improves your accent within weeks."

"Pleasure Reading"

Choosing books or articles you genuinely enjoy so motivation stays high over months of study.

"Harry Potter in English is a popular first pleasure-reading book for intermediate learners."

"Dictation Method"

Listening to a sentence, pausing, and writing it out to sharpen both listening and spelling.

"Dictating BBC radio news clips trains you to distinguish minimal pairs like "ship" and "sheep"."

"The Natural Approach"

Krashen and Terrell's pedagogy that delays speaking, prioritises comprehension, and lowers anxiety.

"A Natural Approach classroom fills the first weeks with storytelling and pictures before asking students to speak."

"Spaced Repetition System (SRS)"

Reviewing flashcards at algorithmically calculated intervals—soon after learning, then increasingly later.

"Anki shows you a word again 1 day, then 4 days, then 10 days after you first learned it."

"Retrieval Practice"

Actively recalling information rather than re-reading it, which strengthens memory traces significantly.

"Closing the textbook and writing everything you remember about a grammar rule is retrieval practice."

"The Testing Effect"

The finding that taking a test—even a self-quiz—improves retention more than additional studying.

"Quizzing yourself with flashcards outperforms rereading notes for long-term vocabulary retention."

"Interleaving"

Mixing different types of practice in one session instead of blocking all one type together.

"Alternating listening, writing, and speaking exercises in 15-minute blocks beats three hours of grammar alone."

"Elaborative Interrogation"

Asking yourself "why?" and "how?" about new material to create richer memory networks.

"For the word "procrastinate", asking yourself why people do it links the word to real emotions."

"Self-Explanation"

Pausing while reading and explaining the material in your own words before continuing.

"After each paragraph of an article, summarising it aloud in English deepens comprehension."

"Keyword Method (Mnemonics)"

Linking a foreign word to a vivid mental image involving a similar-sounding word in your native language.

"To remember "library" in English you picture a lion reading a "libre" (Spanish: free) book."

"Spaced Practice vs. Massed Practice"

Studying in multiple short sessions spread over days beats one long cramming session for long-term memory.

"Three 20-minute vocabulary sessions over three days retains far more than one 60-minute cram."

"Communicative Language Teaching (CLT)"

An approach where the goal of every activity is meaningful communication, not just grammatical accuracy.

"Debating a real news topic in class is a CLT activity; filling in blanks is not."

"Task-Based Language Teaching (TBLT)"

Learners complete real-world tasks (booking a flight, writing an email) and language is the tool, not the focus.

"Planning a fictional trip to London and presenting it to the class is a classic TBLT lesson."

"Content-Based Instruction (CBI)"

Learning English through academic or professional subject matter, so language acquisition is a by-product.

"Studying biology entirely in English at university is CBI in its purest form."

"Language Exchange (Tandem)"

Pairing with a native English speaker who wants to learn your language, so each party practises the other's tongue.

"A 30-minute Zoom with an American learning Spanish: 15 minutes in English, 15 minutes in Spanish."

"Output Hypothesis (Swain)"

The idea that producing language—speaking and writing—pushes learners to notice gaps and improve accuracy.

"Writing a blog post in English forces you to look up words you know in a receptive but not productive way."

"Interaction Hypothesis (Long)"

Negotiating meaning during conversation—asking for clarification, rephrasing—accelerates acquisition.

"A learner asking "Do you mean the big building?" when confused triggers exactly the kind of repair Long described."

"Dogme ELT"

A materials-light approach where conversation and learner-generated language are the primary teaching resources.

"A Dogme teacher might ask students to talk about their weekend and build the lesson from the language that emerges."

"Role Play & Simulation"

Acting out realistic scenarios (job interviews, phone calls) to practise language in low-stakes contexts.

"Practising a doctor's appointment role-play before travelling abroad reduces real-life anxiety enormously."

"Grammar-Translation Method"

Learning grammar rules explicitly and translating sentences between English and your native language.

"The Grammar-Translation Method dominated classrooms for 200 years and is still widely used in East Asia."

"Lexical Approach (Lewis)"

Treating multi-word chunks and collocations as the building blocks of language, not individual words.

"Instead of learning "make" and "decision" separately, you learn the chunk "make a decision" as one unit."

"Grammar in Context"

Studying grammar rules through authentic texts so you see how structures function in real use.

"Noticing how journalists use passive voice in BBC articles is more memorable than a textbook exercise."

"Noticing Hypothesis (Schmidt)"

The claim that you can only acquire a feature if you consciously notice it in input—attention is key.

"Underlining every example of the present perfect in a text forces noticing and speeds acquisition."

"Word Formation Rules"

Learning prefixes, suffixes, and roots to decode and produce thousands of new words systematically.

"Knowing the suffix "-tion" lets you convert "communicate" → "communication" instantly."

"Collocation Training"

Studying which words naturally go together in English, since wrong collocations sound unnatural to native speakers.

""Make a mistake" sounds natural; "do a mistake" is grammatically possible but collocationally wrong."

"Corpus-Based Learning"

Using databases of millions of real English sentences to discover how words are actually used in practice.

"Checking a corpus confirms that "take a shower" is ten times more common than "have a shower" in American English."

"Vocabulary Notebook System"

Recording new words with definition, example sentence, collocation, and image to build a personal reference.

"A well-kept vocabulary notebook with 5 words added daily compounds to over 1,800 words in a year."

"Active Listening"

Engaging fully with audio content—predicting, visualising, and asking questions—rather than passive exposure.

"Before playing a podcast, reading the title and predicting three things you might hear is active listening prep."

"Dictogloss"

Listening to a short text twice, taking notes, then reconstructing it with a partner from memory.

"A teacher reads a newspaper paragraph twice; students piece it back together, noticing any grammar gaps."

"Shadowing (Prosody Focus)"

Specifically imitating the rhythm, stress, and intonation of a speaker, not just individual sounds.

"Shadowing a TED talk speaker's pitch changes and pauses polishes your prosody faster than pronunciation drills."

"Minimal Pairs Drilling"

Practising pairs of words that differ by one sound (ship/sheep, bad/bed) to sharpen perception and production.

"Drilling "bit" vs. "beat" for five minutes a day eliminates a common vowel confusion for Spanish speakers."

"Think Aloud Protocol"

Speaking your thoughts out loud in English while doing everyday tasks to build fluency through constant production.

"Narrating your cooking in English — "Now I'm chopping the onions…" — adds speaking practice to daily life."

"Prepared Speech Practice"

Writing and rehearsing a short speech on a topic, then delivering it several times to build fluency and confidence.

"Giving the same 2-minute speech about your job five times to different partners drastically reduces filler words."

"Tongue Twisters & Articulation"

Repeating phonetically challenging sequences to improve muscle memory for difficult English sounds.

""She sells seashells by the seashore" targets the /ʃ/ and /s/ distinction challenging for many learners."

"Transcription Practice"

Writing out exactly what you hear in a recording, then comparing to the script to catch every word.

"Transcribing a 60-second clip and checking your version against the transcript reveals pronunciation blind spots."

"Affective Filter Hypothesis (Krashen)"

The idea that anxiety, low motivation, and poor self-image block language acquisition even with good input.

"A relaxed, encouraging classroom lowers the affective filter and dramatically speeds up acquisition."

"Growth Mindset for Language"

Believing that language ability is not fixed but develops through effort and good strategy, after Dweck's research.

"Reframing "I made a grammar mistake" as "I'm learning a grammar pattern" is a growth mindset shift."

"Deliberate Practice"

Focused, targeted practice at the edge of your ability with immediate feedback, modelled on Ericsson's research.

"Recording yourself speaking, listening back critically, and practising the specific errors is deliberate practice."

"Time Blocking"

Scheduling fixed, distraction-free slots for English study rather than studying "whenever you have time".

"Blocking 7:00–7:30 AM daily for English produces more progress than irregular 2-hour weekend sessions."

"The Monitor Hypothesis"

Krashen's claim that conscious grammar rules only "monitor" (edit) output, not drive fluency.

"Over-using the monitor makes you pause and self-correct constantly—great for writing, damaging for conversation."

"Input-Output Balance"

Ensuring you consume enough English (reading/listening) to fuel quality production (speaking/writing).

"Most teachers recommend at least 3–4 hours of input for every 1 hour of speaking practice at intermediate level."

"Acquisition vs. Learning (Krashen)"

Krashen's distinction: acquisition is subconscious fluency built from input; learning is conscious rule knowledge.

"A child acquires grammar through play; an adult learner learns grammar from a textbook—Krashen argues only acquisition produces real fluency."

"Accountability System"

Using partners, coaches, public commitments, or tracking apps to maintain consistency over months.

"Posting a daily "30-day English challenge" update on Instagram keeps you accountable through social pressure."
