1. Distinguishing words by meaning
Another method to address spelling errors is by helping students understand the exact meanings of words. Understanding the meaning of a word is crucial. Knowing its meaning is one of the foundations for correct spelling. This is an important feature of Vietnamese orthography, aiding students in overcoming spelling mistakes caused by regional pronunciations. Thus, we can say that Vietnamese spelling, also known as semantic spelling, relies on this understanding.
Explaining word meanings often occurs during reading or vocabulary lessons, but it can also be an effective strategy in spelling lessons when students cannot distinguish difficult words based on pronunciation or word structure analysis.
There are several ways to explain meanings: teachers can ask students to read definitions, create sentences (if students use the word correctly, they understand its meaning), identify synonyms or antonyms, describe characteristics, or use real objects, models, or pictures.
For example: Distinguishing between 'bàn' and 'bàng' (in single words):
- 'Bàn' = a table
- 'Bàng' = the 'bàng' tree
Or distinguishing between:
'Bác' and 'bát':
- 'Bác' = your father’s brother, or Uncle Ho
- 'Bát' = a rice bowl
For multi-syllable words or words with multiple meanings, teachers must place them in specific contexts to help students recall or deduce the word's meaning.

2. Memorizing key spelling rules and tricks
Some common spelling patterns that apply to groups of words can help students effectively improve their spelling. Starting in first grade, students are introduced to simple spelling rules, such as the fact that the consonants 'k', 'gh', and 'ngh' can only combine with the vowels 'i', 'e', 'ê', 'iê', and 'ie'.
The tone rule: The rule of tonal markers (question mark, tilde) in reduplicated words (e.g., 'mát mẻ', 'vui vẻ', 'sạch sẽ'). In reduplicated words with identical initial sounds, the tone (or accent) of the two elements must match either in a high tone (flat, acute, or question mark) or in a low tone (grave, tilde, or heavy). To remember this, teachers can simply teach the principle: High tones = question mark; Low tones = tilde.
This means that for most reduplicated words, if the preceding element has a low tone (grave, tilde, or heavy), the following element will carry a tilde. Conversely, if the preceding element has a high tone (flat, acute, or question mark), the following element will carry a question mark (or vice versa).
Examples:
- Flat + question mark: 'Nhỏ nhoi', 'trẻ trung', 'vui vẻ'
- Acute + question mark: 'Mát mẻ', 'sắc sảo', 'vắng vẻ'
- Question mark + question mark: 'Thỏ thẻ', 'hổn hển', 'rủ rỉ'
- Grave + tilde: 'Mỡ màng', 'lững lờ', 'vồn vã'
- Heavy + tilde: 'Đẹp đẽ', 'mạnh mẽ', 'vật vã'
- Tilde + tilde: 'Dễ dãi', 'nghễnh ngãng', 'nhõng nhẽo'
Additionally, teachers can introduce other mnemonic rules such as:
- To distinguish 'tr' vs. 'ch': Most words referring to household items or animals start with 'ch', for example: 'chăn', 'chiếu', 'chảo', 'chổi', 'chai', 'chày', 'chén', 'chum', 'chạn', 'chõ', 'chĩnh', 'chuông', 'chiêng', 'choé', 'chồn', 'chí', 'chuột', 'chó', 'chuồn chuồn', 'châu chấu', 'chào mào', etc.
- To distinguish 's' vs. 'x': Most plant names and animal names begin with 's', for example: 'Sả', 'si', 'sồi', 'sứ', 'sung', 'sắn', 'sim', 'sao', 'su su', 'sầu đâu', 'sa nhân', 'sơn trà', 'sặt', 'sậy', 'sấu', 'sến', etc.
- To distinguish similar sounding syllables: Most words indicating instability or shakiness contain the syllable 'ênh', such as: 'Gập ghềnh', 'khấp khểnh', 'chông chênh', 'lênh đênh', 'bập bềnh', 'chếnh choáng', 'chệnh choạng', 'lênh khênh', etc. Similarly, words ending in 'ng' or 'nh' are often onomatopoeic, such as: 'oang oang', 'đùng đoàng', 'loảng xoảng', 'đoàng đoàng', etc.

3. Reinforcing learning with spelling exercises

4. Guide students to identify and correct errors

5. Acknowledge and reward students who show progress in their studies
- For students who are doing well or excelling, with neat and error-free work, teachers should leave positive comments in their notebooks and praise them in front of the class.
- For students with frequent spelling mistakes, teachers should spend time helping them correct their errors in class. Every semester, select the top 5 students who have made the most progress to reward them. Rewards could include two notebooks with the teacher’s signature and careful labeling, a refillable pen, or a cap.

6. Actively practice correct pronunciation

7. Differentiate spelling through analysis and comparison
- 'làng' = l + ang + low tone
- 'làn' = l + an + low tone

8. Investigating, identifying, and summarizing common spelling mistakes among students
- Confusing initial consonants (v/d/gi; r/g; x/s; tr/ch).
- Mixing up vowel sounds (o/ô; ă/â).
- Confusing syllables (iu/iêu; in/inh; ui/uôi; un/uôn; êu/iêu; in/iên).
- Mixing up final sounds (n/ng; t/c; i/y; o/u).
- Confusing tone marks (question tone vs. tilde tone).
