Dynamic Assessment (DA) is theoretically derived from Vygotsky's Zone of Proximal Development (ZPD). This study seeks to investigate the effect of Computerized Dynamic Assessment (C-DA) on assisting learners to realize their latent potential in learning reading comprehension. A group of 32 adult EFL students studying English as their BA major in a University in Iran participated in the study. In order to measure the students' potential for learning, Kozulin and Garb's (2002) formula which is called the Learning Potential Score (LPS) was used. The LPSs represented how much mediation was likely required for an individual or a group of individuals to develop or move forward. The results showed that learners with the same pretest scores might turn out to have different or even drastically different DA posttest scores and hence different LPSs. On account of the LPS obtained through the C-DA principles at-risk students are provided with opportunities that might result in overcoming some of the challenges they faced in traditional testing.

Dynamic Assessment (DA) is the integration of Assessment and instruction into a unified activity which derives from Vygotsky’s (1978) theory of the ZPD. An important strand of research that will solidify a central place for DA in the L2 domain is Computerized DA (C-DA) that can be used to assess a large number of students simultaneously while observing the psychometric properties of testing. The present study aimed at designing and validating a test battery of C-DA of grammar for EFL learners named Computerized Dynamic Grammar Test (abbreviated as CDGT). The software reports three scores for a test taker: a non-mediated score, a mediated score and a learning potential score. A pool of 122 homogeneous BA and MA students from different universities participated in this study. The results obtained from the test takers’ scores showed that C-DA is effective in helping students increase their performance and promote their learning development. Data analysis also indicated that C-DA is more effective for low achievers than for high achievers. A major implication of the study is that C-DA can be incorporated in informal and formal testing situations.

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.

The present study reports the results of a dissertation aimed at consolidating Assessment and instruction of L2 pragmatics comprehension by drawing on an interventionist Computerized Dynamic Assessment (C-DA) through which the test was embodied by providing graduated hints (from the most explicit to the most implicit) which were standardized for all test takers. To do so, a web-based software, called a Computerized Dynamic Assessment of Speech Acts, Routines, and Implicatures (CDASRI), accessible at http: //da-pragmatics. com, was developed. Then, 137 upper-intermediate or advanced high school and university students ranging in age from 16 to 36 from two provinces of Khorasan Razavi and Golestan, Iran, were selected based on convenience sampling, who voluntarily took part in the study. Based on how many hints or mediations were used by each test-taker, the CDASRI provided three scores: actual score (traditional score), mediated score, and learning potential score (LPS). The results of the study indicated that the test could improve test takers‟ pragmatic comprehension competence. Moreover, the significant difference between the mediated (using hints) and actual (without hints) scores of learners accounted for the fact that because of test-takers‟ different Zone of Proximal Development (ZPD) levels, their level of responsiveness to mediation was significantly different from one another. Hence, it can be concluded that traditional non-Dynamic test loses sight of a big part of learners‟ abilities through neglecting learners‟ potentialities and putting emphasis only on their preliminary performance. The study concludes with some pedagogical implications for language teachers and instructors who seek an effective perspective for their Assessment and instruction.

Framed in Vygotskian sociocultural theory, this study intends to examine whether Computerized group Dynamic Assessment (GDA) through software has affected Iranian male and female learners’ listening comprehension ability. Data were collected through administration of listening comprehension pre-and post-tests among 140 participants divided into male and female learners in the experimental and control groups. There were 35 male and 35 female learners in each group of the study. Participants in the experimental groups were exposed to GDA in order to interactively work on the selected tasks of listening comprehension, and the teacher provided the necessary support as well. Quantitative analysis of the pre-and post-tests of listening comprehension among male and female groups was conducted through two-way analysis of variance and covariance. Results revealed that both male and female learners in the experimental groups significantly outperformed the learners in the control groups. However, there were not any significant differences between the gender groups’ listening comprehension ability in the experimental groups. Findings contributed to the effective employment of GDA through software in order to improve the learners’ listening comprehension ability, denoting that teachers are recommended to be aware of technological devices in paving an interactive way for learners to develop their language skills and subskills.

In favor of Vygotsky`s Socio-cultural theory and Dynamic Assessment (DA) investigations, the study sought to introduce a novel method to evaluate English-Persian translation proficiency level of translation trainees. Namely, the students` level of independent translation competence and their potentiality for learning were regarded as two factors contributing in the students` classification. Developing a computer-based translation placement test, and using interventionist approach of DA, the translation students participated in this study were categorized into three different levels, moving through two phases. Furthermore, considering the students` proficiency in every translation sub-competence defined in the test, students were narrowly reclassified. The results revealed the newly-made instrument is a valid and reliable scale for evaluating translation trainees` actual as well as potential development. The analysis of the pilot test clearly demonstrated that besides assessing the students` current translation abilities, evaluating their learning potential has a profound impact on providing more thorough classification. The information yielded can be particularly beneficial in the translation students` future instructional planning.

This study investigates the impact of Computerized Dynamic Assessment (C-DA) on grammar learning among Iranian EFL learners, focusing on the moderating role of working memory (WM). A nonrandomized pretest-posttest control group design was employed, with 60 male learners aged 17 to 18 divided into experimental and control groups. The participants were assessed using the Oxford Quick Placement Test (OQPT) to determine language proficiency and a researcher-made test to measure knowledge of past perfect tense. The intervention involved C-DA sessions conducted via the Google Meet platform for the experimental group, while the control group received traditional teacher-fronted lessons. Results from independent-sample t-tests and one-way between-groups ANOVAs revealed a significant improvement in grammar learning among the experimental group compared to the control group. However, no discernable difference was found in the performance of high and low WM learners in response to C-DA. These findings highlight C-DA's potential as a practical instructional approach for grammar learning in EFL contexts. They underscore the need for further research to explore its utility across different learner profiles.

Dynamic Assessment (DA) is theoretically framed within Vygotsky‟ s Socio-Cultural Theory (SCT) and relies on reunification of Assessment and instruction. This process-oriented study of reading comprehension aims at investigating the impacts of applying Computerized Dynamic Assessment (C-DA) which is an ongoing strand of DA on promoting at-risk advanced Iranian EFL students‟ reading skills. The sample of this study comprised of 32 advanced BA students selected based on convenience sampling from Teaching English as a Foreign Language (TEFL) undergraduates from a university in Iran. In this study, the DIALANG software and the Computerized Dynamic Reading Test (CDRT) were utilized to identify the individuals‟ proficiency level and to examine the effectiveness of the enrichment program (EP) in DA respectively. Upon completion of the CDRT, the learners were presented with two mediated and unmediated scores. The formula called Learning Potential Score (LPS) was also utilized in order to measure the students‟ potential for learning. Analysis of the results showed that a pretest (unmediated) score was a sufficient indication neither for measuring individuals‟ ability nor for preparing an effective lesson plan for them. The findings of this investigation may prove to be significantly useful for those who are concerned about individuals requiring a lot of attention, that is, at-risk or retarded learners within the realm of DA.

In the response phase the most important step is to assess disaster after occurrence. By disaster Assessment, we can obtain all the needed information for controlling, decision-making and also disaster planning. Lack of disaster Assessment causes you to make unsuitable decisions based on limited or inadequate data which leads to imperfect disaster response. According to IFRC, disaster response operation will have an unsuitable function without disaster Assessment. This paper presents the principles and concepts of disaster Assessment.

Background & Aims: The aim of this study was to evaluate the accuracy of Cone-beam Computerized Tomography (CBCT) linear measurements in dry mandibles by comparing them with direct measurements.Methods: Two human dry mandibles were used in this study. Thirteen sites were selected on each mandible. Specimens were scanned by CBCT and linear measurements were made using Planmeca Romexis 2.3.0.R software. Mandibles were cut into sections at marked locations and the same distances were measured by a digital caliper. Differences between two methods were assessed using paired t- test.Results: The mean differences for bone height, bone width and the crest-canal distance between CBCT and digital caliper measurements were -0.47±1 mm, -0.14±0.78 mm and 0.00±0.76 mm respectively. The differences were only, significant for bone height measurements (P<0.05). There was a high carreltion between the result of CBCT and gold standard.Conclusion: The results of this in-vitro study on mandible indicate that, although there is a statistically significant difference for bone height measurements between the two methods, the difference is not significant in clinical applications. Thus, CBCT was shown to be a useful technique for preoperative dental implant planning.
