OASYS is a multi-platform and multi-device digital testing and assessment system built around <strong>state-of-the-art web-technologies<\/strong>. In close collaboration with the University\u2019s Human-Computer Interaction (HCI) research group, OASYS has been carefully <strong>designed around business processes, following a research-based HCI approach<\/strong>, thus ensuring optimized user experience. To assure secure data collections and best-possible service, OASYS offers powerful live monitoring for test administrators. Every response is communicated and logged instantaneously on LUCET servers, which minimizes the loss of data even during potential client side computer crashes. Speaking of security, OASYS developers undergo regular security training, and OASYS underwent state-of-the-art <strong>penetration testing and code review by external security consultants<\/strong>. OASYS collects timestamps of every action, thus making the platform an ideal choice for behavioural analysis and data mining. A load balancing solution allows for around 20K simultaneous client connections in the current server setup. Notably, all OASYS <strong>servers are hosted in-house<\/strong>, thus facilitating <strong><a href=\"https:\/\/commission.europa.eu\/law\/law-topic\/data-protection_en\" target=\"_blank\" rel=\"noreferrer noopener\">GDPR compliance<\/a><\/strong>. Although OASYS has been designed primarily as an online assessment system, the client can also run in an app with a server installation on a laptop and a mobile Wi-Fi access point, thus allowing for digital testing in areas with poor or no internet connection. Since 2010, OASYS is <strong>used successfully in the Luxembourg school monitoring programme <a href=\"http:\/\/www.epstan.lu\/\" target=\"_blank\" rel=\"noreferrer noopener\">\u00c9pStan<\/a><\/strong>. Moreover, since 2014, OASYS is also the platform of choice for student course evaluations and various in-house surveys at the 91短视频.<\/p>\n<\/div>\n<\/div>\n<\/div><\/section>\n\n\n\n<section class=\"wp-block-unilux-blocks-free-section section\"><div class=\"container xl:max-w-screen-xl\">\n<p><\/p>\n<\/div><\/section>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":221,"featured_media":0,"parent":2825,"menu_order":1,"template":"","meta":{"featured_image_focal_point":[],"show_featured_caption":false,"ulux_newsletter_groups":"","uluxPostTitle":"Luxembourg Centre for Educational Testing (LUCET)","uluxPrePostTitle":"Research groups","_trash_the_other_posts":false,"_price":"","_stock":"","_tribe_ticket_header":"","_tribe_default_ticket_provider":"","_tribe_ticket_capacity":"0","_ticket_start_date":"","_ticket_end_date":"","_tribe_ticket_show_description":"","_tribe_ticket_show_not_going":false,"_tribe_ticket_use_global_stock":"","_tribe_ticket_global_stock_level":"","_global_stock_mode":"","_global_stock_cap":"","_tribe_rsvp_for_event":"","_tribe_ticket_going_count":"","_tribe_ticket_not_going_count":"","_tribe_tickets_list":"[]","_tribe_ticket_has_attendee_info_fields":false},"field-of-interest":[],"organisation":[170],"authorship":[89,221,301],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.3 (Yoast SEO v22.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Labs - Luxembourg Centre for Educational Testing LUCET - FHSE research group I 91短视频<\/title>\n<meta name=\"description\" content=\"LUCET\u2019s mission is genuinely interdisciplinary, and so is the centre\u2019s expertise.
