The comparative effect of group dynamic assessment (GDA) and computerized dynamic assessment (C-DA) on Iranian upper-intermediate EFL learners’ speaking complexity, accuracy, and fluency (CAF)

Abstract

This study attempted to check the impact of two dynamic assessment (DA) models on speaking CAF. DA, as opposed to static assessment, is conceived as an interactive approach to assessment that integrates teaching and testing into a unified instructional engagement. To achieve the goals of this research, a convenience sample of 90 upper-intermediate male EFL learners that were randomly assigned into GDA, a C-DA, and a non-DA control group participated in the study. Before carrying out the treatment, a speaking pretest was administered to all three groups and their CAF scores were collected. Following that, the treatment using the aforementioned DA and non-DA conventional models was completed in 16 sessions. To check the impact of the treatment, a speaking post-test was given to the groups at the end of the study. Data analysis using ANOVA showed that C-DA and G-DA could significantly increase speaking CAF than the conventional non-DA instruction with C-DA being significantly better than G-DA. The results of this research propose that implementing DA, especially C-DA by the teachers, can enhance the speaking CAF of the L2 learners.

Formative vs. summative assessment: impacts on academic motivation, attitude toward learning, test anxiety, and self-regulation skill

“…The main goal, thus, is to overcome barriers to learning. Assessment is then used to interpret the performances of students, develop learning, and modify teaching (Aouine, 2011 ; Ghahderijani et al, 2021 ).…”

Technology-integration experiences in ELT classrooms as an effective tool: a theoretical study

“…Technology integrations may be characterized as "technology learning, the use of technology in the education process" and "technology integration that enhances learning among students" (Dockstader, 1999). First of all, instructors must gain their technological skills, and this achievement should be integrated into the instructional process and delivered to the students (Ghahderijani et al, 2021;Gorder, 2008). When it comes to integrating technology into the classroom, the focus should be on the education of students (Khan et al, 2021).…”

Dynamic vs. diagnostic assessment: impacts on EFL learners’ speaking fluency and accuracy, learning anxiety, and cognitive load

“…DigA is the other type of assessment that aims at recognizing a student's strengths and weaknesses in the parts the instruction and assessment are founded, later on applying the data gained to aid in the student's learning and conduct the teaching (Jang & Wagner, 2014). It is a type of assessment that relied on feedback that gives pupils the information they want to monitor their development so as to get remedial instruction (Ghahderijani et al, 2021;Kazemi, 2018). Alderson et al (2015) stated that there are some major variances between the diagnostic test and other kinds of language tests: (1) changing the teaching procedure is the primary goal of the test.…”
