Evaluation is a purposeful, cyclical process of collecting, analyzing and interpreting relevant information in order to make qualitative judgments and take decisions concerning to certain performances, materials, activities, courses or programs in the light of certain aims, goals or objectives.
There are two types of evaluation:
1. Formative which is concerned mainly with forming and enhancing the process of learning. It is the ongoing assessment that teachers do into the classroom in order to decide to what extent they achieve their objectives or goals with the aim of making modifications for bringing about improvements.
2. Summative which is concerned with evaluating the whole knowledge of the learner and his/her progress & proficiency.
Evaluation has two sides: Measurement and assessment.
Measurement is the process of using certain tools, criteria and skills in order to make quantitative judgments of students’ achievements. Therefore measurement is impersonal and objective.
Assessment is the act of collecting information on individual learners’ performance proficiency and achievement in the light of certain objectives. Therefore assessment is personal and specific.
