- Currently, DORA (English version) and ADAM (English verision) are supported on iPad/iOS or Android devices. These 2 assessments will either use a non-Flash or Flash version depending on the device used. Our other assessments currently require the use of Flash and thus will not work on tablet or mobile devices. We are working to expand our other assessments to work on non-Flash supported devices.
- IPad/IPhone IOS and Android does not support Flash which our LGL Edge instruction currently requires. We are in the process of converting our system to support these devices and will keep our customers posted when this is available. If you are unsure of a supported browser, please use our flash test here for compatibility
- Any IOS or Android smartphone or tablet requires the "Aug That" application to augmented reality videos and activities. Go to the Apple app or the Android "Google Play" stores to download this free application.
- Augmented Reality Activity sheets are stored as PDF files and can be printed by either Adobe Acrobat or a PDF viewer built into many web browsers.
NETWORK/BANDWIDTH REQUIREMENTS (School/District use)
Overview: Internet bandwidth needs are based upon the number of users who are taking assessments concurrently from your site. The initial start-up of assessments uses the most bandwidth. Once students are in the middle of an assessment, bandwidth needs decrease. Network quality must be sufficient to avoid packet loss when multiple computers are assessing students. Generally, modern network equipment (<3 years old) should be adequate.
Check your bandwith at this site (choose the San Francisco Server): http://www.speakeasy.net/speedtest/
Internet connection requirements:
- DSL, Cable, Satellite, or WiFi Broadband internet connection.
- Internet connection speeds of 1.5M/256K or higher are recommended, though this requirement may vary based on your overall network needs.
Local Area Network requirements:
- LAN, including routers, switches, and network cards, should be 100mBit or greater.
- All labs using the assessments must be on switches, not hubs.
- Chaining a switch into a single port of another switch is not advised unless both switches have 100mBit capacity and are running at full duplex.
- Any old or unusual network configurations may cause network collisions and result in packet loss. This will make the assessment seem as if it is freezing, when in reality, packet loss is preventing the data from reaching the computer running the assessment.
Standard Bandwidth Guidelines:
Single Lab Usage (assuming 30 computers) Mbits/sec
- Normal usage 0.36
- Normal-High usage 0.56
- Spike peak usage* 1.16
Multiple Lab Usage (assuming 100 computers) Mbits/sec
- Normal usage 1.28
- Normal-High usage 2
- Spike peak usage* 2.92
* Labs do not have to meet spike usage needs. This spike may happen if all students start an assessment at once. You may experience a pause of 2 to 10 seconds if your network bandwidth isn't large enough; however, this is considered acceptable at start-up.
Final note: Not conforming to the guidelines above doesn't mean the assessment will not run smoothly. Each network configuration is unique and may need to be assessed further if performance is affected. If there is suspicion of weakness in any area, we suggest you run our online flash test to identify any weaknesses before conducting multiple assessments.
