As assessment plays an important role in the process of teaching and learning, this research explored the impacts of formative and summative assessments on academic motivation, attitude toward learning, test anxiety, and self-regulation skill of EFL students in Iran. To fulfill the objectives of this research, 72 Iranian EFL learners were chosen based on the convenience sampling method assigned to two experimental groups (summative group and formative group) and a control group. Then, the groups took the pre-tests of test anxiety, motivation, and self-regulation skill. Then, one experimental group was trained by following the rules of the formative assessment and the other experimental group was taught according to the summative assessment. The control group was instructed without using any preplanned assessment. After a 15-session treatment, the post-tests of the test anxiety, motivation, and self-regulation skill were administered to all groups to assess the impacts of the instruction on their language achievement. Lastly, a questionnaire of attitude was administered to both experimental groups to examine their attitudes towards the impacts of formative and summative assessment on their English learning improvement. The outcomes of one-way ANOVA and Bonferroni tests revealed that both summative and formative assessments were effective but the formative one was more effective on academic motivation, test anxiety, and self-regulation skill. The findings of one sample t-test indicated that the participants had positive attitudes towards summative and formative assessments. Based on the results, it can be concluded that formative assessment is an essential part of teaching that should be used in EFL instructional contexts. The implications of this study can help students to detect their own weaknesses and target areas that need more effort and work.

Student-centered learning assessment (SCLA) constitutes a major component of current educational initiatives at the University of Technology and Applied Sciences (UTAS). However, little research has been conducted on English teachers’ understanding and practices of SCL assessment. Therefore, this study seeks to explore English teachers’ understanding and practices of SCL assessment at UTAS in Oman. The findings could provide information regarding teachers’ understanding and practices of SCLA. The findings may contribute to how English teachers define SCLA, what SCL-related activities they conduct, and how often these are conducted. Sixty-one teachers participated in the study with an average of 24 years of experience. A series of interviews and questions were used to elicit data from the participants. A questionnaire was used to explore teachers’ understanding of SCLA. Interviews were used in conjunction with the questionnaires to obtain more detailed information from the participants. The findings of this study showed that each of the English teachers has their definitions and understandings of SCLA; however, it was difficult to understand teachers’ definitions of SCLA due to the lack of a common definition for this term in the literature. Teachers should be encouraged to empower students by working in mixed groups on the basis that the advanced students each head up separate groups. The implication is to allow less able students to mimic and imitate their peers and improve their comprehension, pronunciation, and vocabulary in and out of the classroom. Future research could be enhanced by other stakeholders, such as students and administrators, involvement.
