6.1 Coursebook Evaluation, Adaptation, and Supplementation
Key Takeaways
- Coursebook evaluation requires systematically analyzing macro factors (syllabus structure, methodology, level) and micro factors (task design, cognitive load, linguistic authenticity).
- Commercial coursebooks rarely fit a specific classroom context perfectly, necessitating adaptation due to mismatched proficiency, unappealing topics, cultural inappropriacy, or timing constraints.
- Teachers have four strategic options for materials modification — Replacing, Omitting, Adapting (modifying, extending, reordering), and Supplementing — abbreviated in this guide as ROAS.
- Effective coursebook adaptation tailors global coursebook content to local learner needs, interests, and cultural realities while preserving core syllabus objectives.
6.1 Coursebook Evaluation, Adaptation, and Supplementation
The Role of the Coursebook in ELT
In English Language Teaching (ELT), the published coursebook (or textbook) serves as the primary structural spine for many language programs worldwide. A well-designed coursebook provides a coherent syllabus, graded linguistic progression, professional design, audio/visual components, and structured practice tasks. For teachers, it reduces lesson planning pressure and ensures coverage of essential grammatical, lexical, and functional targets. For learners, it offers a predictable learning path, a reference guide, and a record of academic progress.
However, commercial coursebooks are produced for mass global markets. Consequently, no single published coursebook can perfectly accommodate the specific needs, cultural backgrounds, interests, learning styles, and linguistic levels of every individual classroom. Relying blindly on a coursebook without professional intervention can result in disengaged learners, mismatched difficulty levels, or culturally inappropriate content.
Cambridge TKT Principle: A coursebook is a proposal for learning, not a dogmatic script. Effective teachers use coursebooks as a flexible resource to be critically evaluated, adapted, and supplemented rather than followed passively page by page.
Coursebook Evaluation: Macro vs. Micro Criteria
Before selecting or utilizing a coursebook, educators conduct coursebook evaluation. Evaluation occurs at two distinct analytical levels:
-
Macro-Evaluation (Global Analysis):
- Syllabus Design: Is the syllabus structural, functional, task-based, lexical, or multi-layered?
- Target Audience & Level: Is the language level accurately calibrated to the Common European Framework of Reference (CEFR)? Is the visual presentation age-appropriate (e.g., young learners vs. business adults)?
- Methodological Approach: Does the textbook promote communicative language teaching (CLT), inductive discovery, or traditional PPP (Presentation, Practice, Production)?
- Package & Resources: Does it include essential components such as a teacher's book, audio/video downloads, workbook, digital interactive tools, and assessment tests?
- Practicality & Access: Is the coursebook affordable, locally available, and culturally accessible?
-
Micro-Evaluation (Unit and Task Analysis):
- Task Authenticity & Cognitive Load: Do tasks engage real-world communicative skills or rely solely on mechanical drill patterns?
- Language Balance: Is there an equitable integration of receptive skills (reading/listening), productive skills (speaking/writing), grammar, vocabulary, and phonology?
- Clarity of Instructions: Are rubrics concise and clear for learners at the target proficiency level?
- Flexibility: Can individual exercises be modified or reorganized easily during a lesson?
Reasons for Coursebook Adaptation
Teachers adapt coursebook materials when they detect a mismatch between the published content and their actual classroom environment. Primary reasons for adaptation include:
| Rationale for Adaptation | Classroom Reality & ELT Example |
|---|---|
| Mismatched Proficiency Level | The target reading passage contains low-frequency vocabulary or complex syntax that overwhelms lower-intermediate learners, or an exercise is too easy for fast finishers. |
| Unsuitable or Outdated Topic | A reading text features an outdated technology (e.g., using dial-up internet) or a topic with zero interest for teenage learners (e.g., retirement planning). |
| Cultural Inappropriacy or Taboo | Textual or visual references conflict with local cultural norms, religious sensitivities, or social conventions (e.g., references to alcohol consumption or specific dating practices). |
| Inappropriate Interaction Patterns | The coursebook relies heavily on individual silent reading when the lesson objective requires collaborative pair work or communicative interaction. |
| Grammar or Lexical Gaps | The coursebook introduces a complex grammar point (e.g., Present Perfect Continuous) with insufficient controlled practice exercises. |
| Timing & Institutional Constraints | A coursebook unit is designed for 6 hours of instruction, but the institutional schedule allocates only 2 hours per unit. |
Four Options for Materials Modification (ROAS)
To systematically modify coursebook content, teachers choose among four broad options: Replacing, Omitting, Adapting (Modifying/Extending/Reordering), and Supplementing. This guide abbreviates them as ROAS purely as a memory aid — it is not official Cambridge terminology, so expect the exam to name the individual options rather than the acronym.

1. Replacing
Replacing involves discarding an unsuitable coursebook element and substituting an external item that fulfills the exact same pedagogical objective.
- Example: A coursebook unit on public transport features a map and timetable of the London Underground. The teacher replaces the London map with a local metro system map, allowing students to practice directional language using familiar real-world geography.
2. Omitting
Omitting involves cutting out activities, texts, or entire sections that are redundant, overly complex, or irrelevant to class needs.
- Example: In a mixed-ability class short on time, the teacher omits a lengthy, repetitive grammar fill-in exercise on page 42 because students have already demonstrated mastery of the structure during the oral practice phase.
3. Adapting (Modifying, Extending, Reordering)
Adapting alters the internal structure, task demand, or sequence of published material without replacing the core content:
- Modifying (Task Format Change): Changing how a task is executed. For instance, turning an individual silent reading comprehension exercise into an interactive jigsaw reading activity where students exchange missing information in pairs.
- Extending (Adding Depth): Expanding an exercise to provide extra challenge or language production. For instance, after completing a coursebook listening gap-fill about vacation disasters, the teacher extends the task by asking students to role-play a phone call between the traveler and a hotel manager.
- Reordering (Sequence Change): Changing the order of activities within a unit to improve lesson flow. For instance, moving a speaking discussion task from the end of the unit to the beginning to serve as a warm-up and lead-in for schema activation.
4. Supplementing
Supplementing means bringing external materials (worksheets, authentic articles, flashcards, digital games) into the lesson to fill diagnostic gaps in the coursebook syllabus.
- Example: The coursebook provides only five fill-in-the-blank items for practicing past simple irregular verbs. The teacher supplements the lesson with a communicative board game that requires students to form full past simple sentences under time pressure.
Tailoring Materials to Learner Needs and Local Context
Successful materials adaptation aligns coursebook content with learner-centeredness and local contextualization:
- Personalization: Modifying abstract coursebook prompts so that learners talk about their own lives, families, preferences, and local environment. Instead of discussing a generic coursebook character named 'John', students write about their classmate or a local public figure.
- Differentiated Learning: Adapting coursebook tasks to support diverse proficiency levels within a single class. Fast finishers receive extension activities (e.g., creating open-ended questions), while struggling learners receive scaffolded word banks or sentence starters.
- Cultural Sensitivity: Ensuring that adapted or replacement texts respect local socio-cultural norms without stripping away authentic exposure to English-speaking cultures.
By evaluating coursebooks critically and applying the ROAS framework, teachers transform rigid commercial textbooks into dynamic, engaging, and contextually relevant learning experiences.
A teacher notices that a coursebook reading text about skiing in the Alps is completely unappealing and culturally unfamiliar to a class of adult learners in a tropical region. The teacher decides to remove the text and use an authentic article about local eco-tourism instead, while keeping the original reading comprehension questions.
