Dynamic assessment (DA) has been implemented to diagnose language-related issues and to promote second language (L2) learners' development through intervention (Poehner, 2008). The goal is to evaluate not only what a learner can do on his or her own but also how far he or she can go with instructional intervention. Recently, scholars have conducted L2 DA research in a computerized format (C-DA) in which preprogrammed mediational prompts are integrated into the online testing procedures. This breakthrough has yielded promising findings for the scalability of this dynamically administered assessment method. However, due to the fact that it is an emerging field, the possibility of using C-DA to assist in L2 learning requires further examination. This article centers on two projects in which C-DA was used to assess university-level learners' performance in an L2 context. In the first, a listening and reading C-DA project was employed to assess reading and listening comprehension, while the second involved using C-DA to evaluate pragmatic comprehension. We specifically bring into focus how the two approaches address topics including definition of constructs, determination of tasks, design of mediation, scoring procedures, interpretation of scores/performances, and evidence of transfer. Through identifying what has been achieved and what needs to be explored further, we provide a critical analysis of L2 C-DA research and propose future directions for applying this unique technology for helping L2 learners develop language skills. We also examine the pedagogical applications of C-DA in terms of interpreting student performance and developing tailored instruction for individuals with diverse learning needs.

In view of the ambiguity and randomness of the assessment of earthquake scene rescue performance, this paper proposes an integrated assessment method considering quantitative and qualitative influencing factors from three levels: search, rescue and medical treatment. Firstly, this study constructs an assessment index system of rescue performance at the earthquake scene based on the International Search and Rescue Advisory Group (INSARAG) guidelines set by International Search and Response. Secondly, the subjective weights and objective weights of each index were calculated using the hierarchical analysis process (AHP) and cloud model, respectively. The comprehensive weights were calculated using weighted analysis, and the performance assessment results were visually expressed by cloud model images. Finally, the study was applied to an earthquake rescue case with an initial assessment of 4.0065, and its performance was improved by 4.36% when the rescue process was optimized. The assessment results show that earthquake rescue performance can be estimated, and the rationality and effectiveness of the method was validated.

<p class="1"><span lang="X-NONE">Dynamic assessment (DA), as a pro-learning style of assessment, has been investigated in the educational literature for three decades or more. DA has been encouraged by the dearthof conventional static tests to prepare precise information about the individual’slearning abilities, change processes, specific deficient functions, and mediationalstrategies that are in charge for cognitive modifiability. DA, strongly rooted in Socio-cultural Theory (SCT) and Zone of Proximal Development (ZPD), is essentially defined as an approach which takes into account personal differences and their uses for teaching which accepts intervention in the assessment method.</span><span lang="X-NONE">As stated by Lantolf and Poehner (2011), both collaborative functioning and interaction with others in DA differentiates it from traditional assessment. In DA processes, the emphasis is on the process rather than the products of learning. The important point is that dynamic assessment, as opposed to non-dynamic assessment (NDA), does not separate teaching from testing but instead takes them into account as two aspects of the same thing. Many authors have offered that DA could be used in all language skills, while others postulated that it cannot be useful in the ordinary classes. Regarding the significant contributions of DA in EFL/ESL contexts, the present paper, therefore, aims to review some important studies that have implemented DA on different language skills and the process of their research. It brings to the fore different theories underlying DA, including SCT and ZPD. It then elucidates two approaches to DA, namely interactionist and interventionist. It finally suggests some strands of research and emphasizes the implications of other studies conducted on the interplay between language skills and DA. </span></p>

Reasoning skills of students may be improved through a sort of feedback constructed in the dynamic assessment. The research aims to analyze the effect of dynamic assessment on high school biology students' reasoning skills. The research employs a quasi-experimental method with a pretest-posttest control group design. The participants were students of grade X Science Program (N=61), which were selected purposively. Data on reasoning skills was collected by pretest and posttest focused on the concepts of bacteria. with dynamic assessment method. The data analysis technique employs an Independent sample t-test. The research result indicate that Dynamic Assessment provides better effect on students’ reasoning skills in Bacteria material.

Although creating a high-quality urban green space (UGS) is of considerable importance in public health, few studies have used individuals’ emotions to evaluate the UGS quality. This study aims to conduct a multidimensional emotional assessment method of UGS from the perspective of spatial quality. Panoramic videos of 15 scenes in the West Lake Scenic Area were displayed to 34 participants. For each scene, 12 attributes regarding spatial quality were quantified, including perceived plant attributes, spatial structure attributes, and experiences of UGS. Then, the Self-Assessment-Manikin (SAM) scale and face recognition model were used to measure people’s valence-arousal emotion values. Among all the predictors, the percentages of water and plants were the most predictive indicators of emotional responses measured by SAM scale, while the interpretation rate of the model measured by face recognition was insufficiently high. Concerning gender differences, women experienced a significantly higher valence than men. Higher percentages of water and plants, larger sizes, approximate shape index, and lower canopy densities were often related to positive emotions. Hence, designers must consider all structural attributes of green spaces, as well as enrich visual perception and provide various activities while creating a UGS. In addition, we suggest combining both physiological and psychological methods to assess emotional responses in future studies. Because the face recognition model can provide objective measurement of emotional responses, and the self-report questionnaire is much easier to administer and can be used as a supplement.
