Materials evaluation involves measuring the potential value of learning materials using judgments about their effects on users. It considers criteria like appeal, credibility, validity, ability to interest and motivate learners, and value for short and long-term learning. Effective materials also align with principles of second language acquisition, such as achieving impact, making learners feel at ease, developing confidence, perceived relevance, self-investment, developmental and psychological readiness, attention to linguistic features, communicative opportunities, and accounting for differences in learning styles and attitudes.

2. WHAT IS MATERIALS EVALUATION?
•Materials evaluation is procedure that
involves measuring the value (or potential
value) of a set of learning materials.

3. It involves making judgments about the effect of the materials
on the people using them and it tries to measure some or all of
the following:
1. The appeal of the materials to the learners.
2. The credibility of materials to learners, teachers, and
administrators.
3. The validity of the materials.
4. The reliability of the materials.
5. The ability of the materials to interest the learners and
the teachers.
6. The ability of the materials to motivate the learners.
7. The value of the materials in terms of short-term
learning (important, for example, for performance on
tests and examinations.

4. 8. The value of the materials in terms of long-term learning
(of both language and communication skills)
9. The learners’ perceptions of the value of the materials.
10. The teachers’ perceptions of the value of the materials.
11. The assistance given to the teachers in terms of
preparation, delivery, and assessment.
12. The flexibility of the materials.
13. The contribution made by the materials to teacher
development.
14. The match with administrative requirements.
It involves making judgments about the effect of the materials
on the people using them and it tries to measure some or all of
the following:

5. Second Language Acquisition (SLA) Principles
Some of these principles are summarized below:
1. Materials should achieve impact.
2. Materials should help learners to feel at ease.
3. Materials should help the learners to develop
confidence.
4. What is being taught should be perceived by learners as
relevant and useful?
5. Materials should require and facilitate learner self-
investment.
6. Learners must be ready to acquire the points being
taught both in terms of linguistic, developmental
readiness and of psychological readiness too.

6. 8. The learners’ attention should be drawn to linguistic features
of the input.
9. Materials should provide the learners with opportunities to
use the target language to achieve communicative purposes.
10. Materials should take into account that the positive effects
of instruction are usually delayed.
11. Materials should take into account that learners differ in
learning styles.
12. Materials should take into account that learners differ in
affective attitudes.
13. Materials should maximize learning potential by
encouraging intellectual, aesthetic and emotional involvement
which stimulates both right and left brain activities.
