Our Expertise
The LexFizz Team brings together practitioners with complementary specialisations in English language education. Our content is produced and reviewed by people who have taught English at classroom level — not by generalists or content agencies without language teaching credentials.
Core areas of expertise include:
- ESL and EFL teaching: Classroom experience at A1–C2 levels, across general English, business English, and exam preparation contexts.
- CEFR framework application: Thorough familiarity with the Council of Europe's Common European Framework of Reference — including the 2020 Companion Volume — and its practical application to level assignment, vocabulary selection, and task design.
- Vocabulary research and pedagogy: Working knowledge of high-frequency word lists (Oxford 3000, NGSL, AWL), corpus linguistics, and evidence-based approaches to vocabulary instruction including spaced repetition and deliberate vocabulary learning.
- Grammar instruction: Ability to explain grammar rules clearly at the appropriate level, identify and address common learner errors, and provide natural, contextualised examples aligned with exam expectations.
- Digital learning design: Experience designing interactive exercises that apply communicative language teaching (CLT) principles and motivational design to digital environments.
What We Create
The LexFizz Team is responsible for all original content on this platform, including:
- Interactive exercises: 30 browser-based English exercises across vocabulary, grammar, spelling, listening, and reading categories. All exercise content — word lists, example sentences, question stems, and answer keys — is written and reviewed by the team.
- Grammar guides: In-depth blog articles covering core English grammar topics at CEFR levels A1–C1, with structure explanations, example sentences, common error analysis, and links to practice exercises.
- Vocabulary resources: Topic-based and frequency-based vocabulary articles, including thematic word lists, collocations, and usage notes grounded in Oxford and corpus references.
- Teaching articles: Practical guides for ESL/EFL teachers on topics including classroom game-based learning, exercise design, and English learning methodology.
- Exam preparation content: IELTS-specific vocabulary and writing guides cross-referenced with Cambridge Assessment CEFR descriptors.

Use the contact page at lexfizz.com/contact/ to reach the team. We welcome error reports, topic suggestions, questions about content, and feedback from teachers using LexFizz in the classroom. We aim to respond to all substantive feedback within 7 working days.
Does the LexFizz Team follow editorial guidelines?
Yes. All content produced by the team is governed by the LexFizz Editorial Policy (lexfizz.com/editorial-policy/), which covers fact-checking requirements, CEFR level assignment procedures, the annual content review cycle, and the platform's independence from sponsorship and affiliate arrangements. No content is published without review against these standards.
Is LexFizz content written by AI or by humans?
Content is produced by the human ESL specialists on the LexFizz Team. Any AI-assisted drafting tools are subject to the full editorial review process — fact-checking, example verification, CEFR level-checking, and clarity review — before publication. No content goes live without human expert oversight and sign-off.
What is the LexFizz Team's approach to grammar teaching?
The team follows a communicative language teaching (CLT) approach, presenting grammar rules in context with natural example sentences drawn from authentic English use. Rules are verified against authoritative references (Cambridge Grammar of English, Swan's Practical English Usage) and common learner errors are addressed directly. Explanations are written at the level of the intended CEFR audience — not in overly academic metalanguage.
How does the team handle disagreements in grammar guidance between sources?
When authoritative sources differ — for example, on prescriptive vs. descriptive usage, or British vs. American English conventions — the team notes the variation explicitly in the content and recommends the form most appropriate for the learner's likely goal (often exam preparation). We do not pretend grammar is more clear-cut than it is, and we cite our references so learners can investigate further.
Can teachers request specific exercise topics or article subjects?
Yes. We actively welcome topic requests from teachers who use LexFizz in the classroom or recommend it to students. Use the contact page to submit a suggestion, including the target CEFR level and the grammar or vocabulary topic you would like covered. We prioritise topics that address genuine learner needs and are not already well covered on the platform.
