Understand how English is built before optimising IELTS performance
The foundation programme no longer stops at pronunciation. It connects written symbols and sounds to word formation, phrase structure, finite clauses and complete academic sentences.

Subject + Finite predicateKN Language Construction Model
English is assembled hierarchically, not as a flat string of words
Each output becomes the input of the next layer. A sentence is complete only when the clause core is structurally closed; modifiers and additional clauses are then attached without breaking that core.

Signal control
Can the learner recognise and produce the form?
Structural control
Is the clause complete, and are its components connected correctly?
Task transfer
Does the sentence express the intended academic relation clearly?
Foundation principles
Control the hierarchy before increasing linguistic complexity
The same engineering logic is applied from sound to sentence: identify the governing element, distinguish required from optional components, observe the output and correct one variable at a time.
01Locate the governing element
02Build the minimum complete structure
03Attach optional information by rule
04Verify the output in a real task
P01SIGNAL
Written form and spoken form are related but not identical
English spelling encodes historical and morphological information as well as sound, so one letter is not guaranteed to represent one phoneme.
Use letter names for spelling, phonemes for pronunciation and word patterns for prediction.
P02PHRASE
Every phrase is organised around a head
The head determines the phrase type and controls number, complementation and the main reference of the phrase.
Find the head before analysing modifiers; otherwise long phrases appear structurally opaque.
P03CLAUSE
A complete sentence is anchored by a finite clause
The finite operator carries tense or modality and establishes the grammatical relation between subject and predicate.
Before adding detail, verify that the sentence already contains a subject and a finite predicate.
P04CLAUSE
The main verb selects the clause pattern
Different verbs license different complements: no object, one object, two objects, a complement or an obligatory adverbial.
Do not translate a Vietnamese word order directly; check the English verb frame first.
P05SENTENCE
Complexity comes from controlled relations, not sentence length
Coordination, subordination, relative clauses and non-finite clauses each create a different structural and logical relation.
Name the intended relation first, then choose the linker and punctuation that encode it.
P06TRANSFER
Learning requires observable output and corrective feedback
A rule is not mastered when it is merely recognised; it must be produced, tested in context, diagnosed and re-tested.
Every lesson links explanation, model decomposition, controlled practice and an explicit verification boundary.
KN English Foundations Course
From acoustic signal to controlled academic sentences
The course now has two coupled systems: sound–spelling control and sentence architecture. Each stage contains a small set of lessons, then opens a full-width theory and lab workspace below.

F01 · Signal system
Alphabet & spelling
Master letter names, spelling sequences and high-risk contrasts used in names, addresses, codes and Listening answers.
F01.01 · A1Alphabet & spelling
Letter names are not word sounds
Separate the spoken name of a letter from the sound or sounds that the spelling can represent inside a word.
Lesson instrument
Observe first, then adjust one variable at a time
01 Input02 Listen03 Compare04 Correct
Grapheme–sound inspection lab
Separate the letter symbol, its name and its sound behaviour inside words
A letter name is a label for the written symbol. It is not a universal pronunciation rule for every word containing that letter.

Practice targets
In this lesson, you will practise
Each target is linked to an observable task later in the lesson.
- 01Say all 26 letter names accurately.
- 02Explain why A in age and A in cat are different.
- 03Avoid using Vietnamese letter names when spelling in English.
Core mechanism
Identify the variable that changes the output
Treat examples as observations of the mechanism: compare what changes and what remains constant.
Letter name
The conventional name used when spelling, such as A /eɪ/ and R /ɑː/ or /ɑːr/.
A /eɪ/J /dʒeɪ/R /ɑː, ɑːr/Sound value
The sound represented inside a word. One letter may represent several sounds.
cat /kæt/cake /keɪk/about /əˈbaʊt/Spelling function
Letter names are used to transmit exact written forms such as names, codes and email addresses.
K-Nroom B-14kim@example.comError diagnosis
Trace the error from observed form to controlling cause
Observed form
A = /a/ in every wordTarget form
A has several sound valuesEnglish spelling is not one-letter-one-sound.
Observed form
R = Vietnamese 'rờ'Target form
UK /ɑː/ · US /ɑːr/Use the English letter name, not the Vietnamese alphabet name.
Verification gates
A lesson is complete only when the learner can explain, construct and transfer the form
G1
Explain
State the governing rule and identify the controlling element.
G2
Decompose
Separate the observed form into sound, phrase and clause components.
G3
Construct
Produce a complete form without copying a Vietnamese structure directly.
G4
Transfer
Use the controlled form in listening, speaking and an IELTS Academic task.
