Investigating the differential effects of formative and summative assessment on efl learners’ end-of-term achievement

Abstract

In this study, an attempt has been made to highlight the importance of summative assessment in conjunction with teacher-based (formative) assessment on the learning. 107 advanced EFL learners in 3 classes were selected and grouped based on the type of assessment they received. Participants in this study were given tests for two main reasons. First, a general test of proficiency was administered in order to place the learners in different proficiency levels. Second, in an attempt to compare learners’ improvement based on different types of assessment within a 4-month learning period, an achievement test of the course was given two times, as pre and post-tests. The data obtained through learners’ scores on achievement tests were analyzed and then compared using ANOVA, ANCOVA and t-test. In light of the results of this study, it can be argued that a combination of formative and summative assessments can lead to higher achievements of EFL learners than either formative or summative assessment separately.
