Proofing – Automated Spell‑Check and Its Limitations
Learning Objective (AO2, AO3)
Know and understand that automated suggestions given by spell‑check software do not always give the correct response. Be able to combine spell‑check with other validation and manual proof‑reading techniques to produce error‑free ICT‑based solutions (AO2) and evaluate the suitability of the proofing process (AO3).
1. Purpose of Spell‑Check and Why It Can Be Misleading
How it works: compares each word with a built‑in (or user‑defined) dictionary.
What it does not do: analyse meaning, context, or logical consistency of a sentence.
Typical limitations
Proper nouns, brand names, acronyms and technical terms may be absent from the dictionary.
Homophones (e.g., their / there) are spelled correctly but can be used incorrectly.
Words with multiple meanings may be replaced by a synonym that changes the intended sense.
Formatting issues such as hyphenation, apostrophes or numeric separators can trigger false errors.
Dictionary‑based checks ignore data‑validation rules (range, length, format) that are crucial in spreadsheets and databases.
In ICT, proofing also includes checking that data entered into a document, spreadsheet or web form meets specific criteria. The table below summarises the four core checks and shows the typical menu path for the most common exam software (Microsoft Excel / Google Sheets).
Check Type
What It Verifies
Typical Tool
How to Set It (Excel → Data Validation)
Example
Range check
Value lies between a minimum and maximum
Data‑validation dialog
Data → Data Validation → Allow = Whole number → Data → between 5 and 120
Age must be between 5 and 120.
Length check
Number of characters or digits
Form‑field properties (HTML, Access)
Data → Data Validation → Allow = Text length → between 6 and 6
Postcode exactly 6 characters.
Format / pattern check
Specific pattern such as date or email format
Regular‑expression validation
Data → Data Validation → Allow = Custom → Formula = =AND(ISNUMBER(A1),LEN(A1)=10)
Read the text aloud – helps catch missing words and homophone errors.
Peer review – a second set of eyes can spot context‑related mistakes.
Double‑data entry (for numeric tables) – enter the same data twice and compare.
Use a checklist (e.g., “Proper nouns? Acronyms? Hyphenation? Numeric format?”).
Print a hard copy – visual scanning on paper often reveals errors missed on screen.
4. Other Automated Proofing Tools (Exam Relevance)
Grammar‑check: detects subject‑verb agreement, article misuse and some punctuation errors. Useful for AO3 questions that require clear communication.
Style‑check: flags passive voice, overly long sentences and inconsistent heading formats. Relevant when the exam asks you to improve the readability of a document.
Accessibility check: ensures alt‑text for images, sufficient colour contrast and logical heading order. Often appears in AO3 tasks that ask you to evaluate an ICT artefact for a diverse audience.
All these tools are supplements; their suggestions must always be verified manually.
5. Spell‑Check Limitations – Common Error Types
Error Type
Example in Text
Typical Spell‑Check Suggestion
Correct Action
Proper noun not in dictionary
We visited the Alhambra yesterday.
Alhambra → Alhambrae
Ignore suggestion; add “Alhambra” to the personal dictionary.
Homophone misuse
Their going to the market.
Their → There
Identify grammatical error; replace with “They’re”.
Technical term / acronym
The server uses IPv6 addressing.
IPv6 → I·P6
Accept original; add “IPv6” to the custom dictionary.
Hyphenation
A well known author.
well → well‑
Insert hyphen where appropriate: “well‑known”.
Apostrophe misuse
Its a great day.
Its → It’s
Determine meaning; if possessive, keep “its”.
Numeric formatting (spell‑check blind spot)
The total is 12,34 dollars.
No suggestion – flagged as correct spelling
This is a format error, not a spelling error. Apply a format/decimal‑separator validation and correct to “12.34”.
6. Steps to Verify Spell‑Check Suggestions (Quick‑Reference Checklist – AO2)
Read the sentence aloud to confirm the intended meaning.
Ask: Is the flagged word a proper noun, acronym, or specialised term?
Identify the grammatical role (noun, verb, adjective, adverb).
Check numeric or date entries against the required validation rules (range, format, data‑type).
Consult a reliable reference (dictionary, subject glossary, style guide) if unsure.
Update the personal dictionary with correct specialised words for future use.
Record the decision (accept, reject, modify) – this demonstrates AO3 evaluation of the proofing process.
Students work in pairs to proof a mixed‑media document that includes a short paragraph of text, a simple spreadsheet table, and a slide title.
Text paragraph – contains at least three proper nouns, two homophone errors, one technical term, and one hyphenation mistake.
Spreadsheet table – includes a numeric entry with an incorrect decimal separator and a date entered in the wrong format.
Presentation slide – title uses inconsistent capitalisation and a missing apostrophe.
Each pair will:
Run the paragraph through the spell‑check and grammar‑check features of a word processor.
Apply data‑validation tools (range, format, length, data‑type) to the spreadsheet.
Record every suggestion made by the software.
Using the checklist from section 6, decide whether to accept, reject or modify each suggestion.
Produce a corrected document that meets the following specification:
All spelling, grammar, hyphenation and punctuation errors removed.
All numeric and date entries conform to the given format (e.g., “dd/mm/yyyy”, decimal point “.”).
Slide titles follow title‑case style and include required apostrophes.
Present the original and corrected versions, explaining why particular suggestions were inappropriate and how validation checks were applied (demonstrates AO3).
8. Key Points to Remember
Spell‑check is a useful tool but not a replacement for human proofreading.
Always consider context, grammatical role and any required data‑validation rules before accepting a suggestion.
Maintain and regularly update a personal dictionary for recurring specialised terms.
Combine spell‑check, grammar‑check, style‑check, accessibility‑check and manual techniques for the most reliable proofing.
Proofing is required for all ICT artefacts – documents, spreadsheets, presentations and web pages.
9. Assessment‑Style Questions (Mapped to AO)
AO3: Explain why a spell‑check program might flag the word “Google” as an error.
AO2: Give an example of a homophone error that spell‑check would not detect, and show how you would correct it.
AO2: Describe the steps to add the term “IoT” (Internet of Things) to your spell‑check personal dictionary.
AO3: Identify the flaw in the following suggestion: “The committee’s decision was final.” → “committee’s” changed to “committees”.
AO2: In a spreadsheet, the cell contains “12,34”. Spell‑check does not flag it. Which validation check would you apply and what correction is required?
