Diagnosing L2 Receptive Vocabulary Development Using Dynamic Assessment: A Microgenetic Study
Authors
Abstract:
The present study is an attempt to shed light on the effect of Dynamic Assessment (DA) on diagnosing and developing the receptive vocabulary abilities of upper-intermediate learners learning English as a foreign language. Fifty L2 leaners participated in the First Certificate in English test and completed Vocabulary Knowledge Scale. Out of 50 students, ten learners who were identified as being homogenous and were not familiar with the new vocabularies volunteered to participate in individualized tutoring sessions. Reading texts were used to make learners familiar with the target words and cloze passages were administered to assess learners’ receptive vocabulary. Mediation was provided using the interactionist approach to DA and learners’ responsiveness to mediation were studied in a microgenetic approach. The qualitative data were then coded in terms of task completion along with errors and struggles and transformed into quantitative data for analysis. The actual, mediated and transfer scores were reported to analyze learners’ Zone of Actual Development (ZAD), and the degree of the internalization of mediation. Findings of the study revealed that to have a complete picture of learners’ abilities, actual scores are not self-sufficient. Mediated scores are vital to diagnose learners’ areas of difficulties and to promote learners’ receptive vocabulary knowledge. The information from transfer scores also uncovers evidence of learning and data from Learning Potential Score (LPS) predict how learners probably respond to future instruction. Findings of the study indicate that DA is promising in presenting a fine-grained diagnosis of learners’ receptive vocabulary development while also suggesting information related to future teaching and learning.

dynamic assessment according to vygotskys sociocultural theory, states that instruction and assessment are interrelated. using static forms of assessment with second and foreign language students could do more harm than good. many teachers neglect to take account of the complexity involved in learning a second or foreign language and often wonder why learning of a language take so long. thi...
Beyond static assessment of children's receptive vocabulary: the dynamic assessment of word learning (DAWL).
BACKGROUND Children's low scores on vocabulary tests are often erroneously interpreted as reflecting poor cognitive and/or language skills. It may be necessary to incorporate the measurement of word-learning ability in estimating children's lexical abilities. AIMS To explore the reliability and validity of the Dynamic Assessment of Word Learning (DAWL), a new dynamic assessment of receptive v...

The objectives of this study were (a) to examine the writing performance of L2 learners on the level-specific tasks based on Common European Framework of Reference (CEFR) and (b) to study the likely difference between students' self-assessed level of writing and those reported by raters. The study was conducted with 138 Iranian students at BA and MA levels in Alborz Institute of Higher Educatio...

Cochlear implants (CIs) provide children with profound hearing loss access to sounds and speech. Research on the effects of CI on speech and language development in mainland China is scarce due to the lack of standardized tests. This study aims at developing a vocabulary measure, the Mandarin Expressive and Receptive Vocabulary Test (MERVT), for pre-school children with CIs. Using responses fro...
