![]() ![]() In this case at Wenzao University, “offline mode was mistakenly chosen which meant that with hundreds of students all starting a large download at the same time the system became slow.” Clearly, 500 test takers all starting a 30MB download at the same time is going to challenge the most robust of systems. If you have a large number of students doing the test together and you choose offline mode, it is essential that they download the test in advance. Practical details Organising offline mode download This will happen either immediately (if the device is connected) or as soon as a connection is re-established. The test taker can leave their WiFi connection on, or turn it off: the internet now plays no part in the test until the upload of the final result. The test will go live at the time specified by the Administrator in the Admin Panel setup. In the case of naval installations or prisons, devices can be prepared offsite.Īs soon as the download is complete, it is ready to go and no further action is required. The download can be done at a time of lower internet traffic, in a coffee shop, library, or anywhere else that the student can get wifi or data. The download is about 33.6MB, a little less than the average iOS app file size (34.3MB in January 2020), so by no means large. This means that students must download the test in advance. The quality of connections was therefore difficult to gauge, so it was safer to choose offline mode. This was during the lockdown, so there was exceptionally high internet usage in the apartment blocks: some people were working from home, others were binge watching movies. Brunel University Admissions required students to take the test at home in the evening. ![]() In this case, however, there were other factors at work. Much is made of the Great Firewall of China, but at Clarity we have not found that it has an impact on our delivery of testing and learning materials. They will not have to start again from the beginning, and data will not be lost. Note that even if there is an unexpected internet outage, test takers will be able to continue as soon as the connection is re-established. This means that students do not have to remember to download the test in advance, and it means a smaller overall download (offline mode requires a download of all items from A1 to C2, whereas online mode only downloads what is required for a given student’s test path). If your internet connection is robust, it is better to opt for the default online mode. Scenario 1: Good internet connectionĮxample: Testing at Universitas Indonesia Let’s look at a couple of scenarios, and then move on to some practicalities. But if you don’t have a good connection, you can download the whole thing in advance and it will run with no internet connection at all, uploading results for the administrator to see in the Admin Panel the next time you connect. ![]() What does this mean in practice? In essence, if you have a good internet connection, you can run it online and the test items and media will download as they are required. This meant building it with both online and offline modes. Most people have unstable internet at home.īack in 2015 when we first visualised what the Dynamic Placement Test might look like, one guiding principle was that it had to be democratic: these groups had to be catered to it was not going to be a test restricted to those with high-speed broadband. ![]() For other groups, internet connections may be intermittent, unreliable, or simply weak. At Clarity, we still provide CD-ROMS to remote schools in Afghanistan and Ethiopia, and to learning communities which can’t go online for security reasons, such as correctional facilities or naval installations. For many students internet access is no more than a dream. ![]()
