Computerized Dynamic Assessment of Incidental Vocabulary Learning: A Case of Iranian ESP Learners(مقاله علمی وزارت علوم)
حوزههای تخصصی:
Dynamic assessment (DA) has been widely researched in different linguistic areas, but there is paucity of research on its incorporation into English for Specific Purposes (ESP). Accordingly, this study investigates the effectiveness of DA on incidental vocabularies emerging in technical reading textbooks with a focus on electronic engineering students. The research method is a quasi-experimental research design focusing on an intact group of 25 Bachelor of Science students of electronics from the University of Zanjan, Iran. The instruments used are Preliminary English Test (PET), a vocabulary knowledge scale, and a mediation test (a 13-item multiple-choice test). The mediation test was delivered through the researcher-developed website, designed for this purpose. As a triangulation, participants’ evaluation of computerized dynamic assessment (CDA), too, was elicited using a survey adopted from Nirmalakhandan (2007). The results of the qualitative and quantitative phases indicated that Electronic students’ incidental vocabulary learning promoted dramatically using target CDA, employing structured prompts for the mediation process. The results of this study can inform both teachers and learners by providing a step by step procedure for both teaching and assessment of ESP learners' vocabulary.
