The student experience with different aspects of online instructional settings has been the focus educational practitioners and researchers in many studies. However, concerning technology-enabled formative assessment, little is known about satisfaction regarding possible e-assessment strategies students are involved in. Using a 5-point Likert scale questionnaire, web-based survey was developed to examine students’ within an enriched virtual blended course. results show that, general, were...

Purpose This paper aims to explore the perspectives of university students on learning management system (LMS) and determine factors that influence user experience outcomes e-learning. Design/methodology/approach employs a mixed-method approach. For qualitative data, 20 semi-structure interviews were conducted. Moreover, for quantitative short survey was developed distributed among potential respondents. Findings The results showed students, particularly in programs where courses are mainly...

To identify factors associated with client perceptions of the quality primary care services in Afghanistan. Cross-sectional survey outpatient health facilities, workers, patients and caretakers. Primary facilities every province Numerical scale service quality. Clients report relatively high levels perceived Most variation that is explained relates specifically to patient's interaction worker not other facility characteristics, such as cleanliness, infrastructure, capacity presence equipment...

Human epidermis, as the largest organ on body, has become a new design platform for wearable computing. The availability of miniature electronics makes more possibilities on-skin designs. In this paper, we present AnimSkin, thin-film interface, which will emit dynamic color animations directly skin. This is done by using thermochromic material embedded with transparent electrode acting capacitive sensor. Moreover, an accessible and low-cost fabrication method introduced. Individuals could...

Generative AI (GenAI) provides new opportunities for creativity support, but the phenomenon of GenAI design fixation remains underexplored. While human typically constrains ideas to familiar or existing solutions, our findings reveal that similarly experience fixation, limiting its ability generate novel and diverse outcomes. To advance understanding we propose a theoretical framework includes definition, causes, manifestations, impacts creative design. We also conducted an experimental...

Airflow is recognized as an effective method for inducing the illusion of self-motion (vection) and reducing motion sickness in virtual reality. However, quantitative relationship between airflow perceived consistent with it has not been fully explored. To address this gap, study conducted three experiments. In Experiment 1, we carried out a series cross-modal matching tasks to establish speed it, revealing strong linear correlation. 2, introduced concept "Airflow Gradient" simulate bodily...

This paper analyses the effect of wealth status on care-seeking patterns and health expenditures in Afghanistan, based a national household survey conducted within public facility catchment areas. We found high rates reported care-seeking, with more than 90% those ill seeking care. Sick individuals from all quintiles had although wealthiest quintile were likely to seek care poorest (odds ratio 2.2; 95% CI 1.6, 3.0). The nearest clinic providing government's Basic Package Health Services...

More and more social Q&A platforms are launching a new business model to monetize online knowledge. This monetizing process introduces complicated cost benefit tradeoff users, especially for askers' concerns. Much of the previous research was conducted in context free‐based platform, which hardly explains triggers that motivate pay intention. Based on theories exchange capital, this study aims identify examine antecedents intention from perspective cost. We empirically test our...

Abstract This report presents a case study of the development an interface for novel and complex form document retrieval: searching texts written in foreign languages based on native language queries. Although underlying technology achieving such search is relatively well understood, appropriate design not. A involving users from beginning process described, it covers initial examination user needs tasks, preliminary testing components, building, testing, refining interface, and, finally,...

Afghanistan has used several approaches to contracting as part of its national strategy increase access basic health services. This study compares changes in the utilization outpatient curative services from 2004 2005 between different for contracting-out non-governmental service providers, contracting-in technical assistance at public sector facilities, and facilities that did not use contracting. We find both are associated with substantial double difference increases compared...
