1. UMG "St. Ivan Rilski"1 Possibilities for Implementing Contemporary IT Achievements in E- learning Systems assoc prof. K. Ivanov PhD Eng. K. Tcholakov B. Stoineva UMG St Ivan Rilski

2. UMG "St. Ivan Rilski"2 Classics, E-learning, M-learning Old school style Teacher (almighty) Student (it’s all about him) e–learning Teacher (consultant, expert, mentor) Knowledge database (courses, tutorials, tests) Student (it’s all about him) m–learning accessible information and knowledge, any place, any time = e–learning + mobility

3. UMG "St. Ivan Rilski"3 See, touch, try experience SCADA and HMI (industry classics ) Simulation software (tools currently available) Telemetry and emulation of processes – all connected laboratories, available for real- time remotely controlled experiments

4. UMG "St. Ivan Rilski"4 Laptops in M-learning FeaturesPowerful CPUs, big HDD capacity, 3D Video acceleration, network connectivity trough 802.11a, 802.11b, 802.11g, IRDA, USB, Firewire, Ethernet, telephone modem, upgradeability trough industrial standard bus technologies, build in several pointing devices etc, etc. FlexibilityEvery advantage of a desktop PC is brought to the mobile user. Often in a laptop there are features that the owner never uses. PriceLaptop $ = Desktop PC $ * (1,5 up to 2,5)

5. UMG "St. Ivan Rilski"5 OLPC – bare necessities 500MHz CPU, 1G Flash storage, inexpensive LCD technology, network connectivity trough mesh routing, free software, external power independence (wind-up power), robust design… Total: $100

6. UMG "St. Ivan Rilski"6 PDAs in M-learning FeaturesPocket size design, touch-screen display handwriting recognition, Internet ready trough various optional network interfaces. FlexibilityIntuitive interface, software extensibility, multimedia functionality. Moderate next to no hardware upgrade possibilities PriceStill suffering from high standard image device.

7. UMG "St. Ivan Rilski"7 Networking in the mobile world To be truly wired, you must be wireless. — Wired, October 1997. WPANs: Wireless Personal Area Networks WLANs: Wireless Local Area Networks WMANs: Wireless Metropolitan Area Networks WWANs: Wireless Wide Area Networks

8. UMG "St. Ivan Rilski"8 WPANs: Wireless Personal Area Networks UseWireless networking for devices in small (10m) radius StandardsBluetooth 802.15.1 ZigBee 802.15.4 Features10m radius, up to 723.1 kbit/s, 2.5mW-100mW, 8 devices connected in a piconet 10m radius with mesh routing, up to 250 kbit/s Special power saving techniques, 65k devices on one network

9. UMG "St. Ivan Rilski"9 WLANs: Wireless Local Area Networks UseWireless networking for devices in close (n.100m) radius Standards802.11a, 802.11b, 802.11g, 802.11n Features Widely available technology Relatively inexpensive hardware, Speeds up to 11 Mb/s – 108 Mb/s Reverse compatibility trough standards (except for a) Improved security since first introduction.

10. UMG "St. Ivan Rilski"10 WMANs: Wireless Metropolitan Area Networks UseWireless networking for devices in up to 50km radius Standards802.16 (line of site), 802.16a (mesh) (Last mile solutions) Features Point to multipoint, QoS, operates at 10-66GHz, (2- 11GHz - a), 70Mbits/s, Solution supposed to offer inexpensive alternative to wired communications – some highly urbanized locations could benefit from it too.

11. UMG "St. Ivan Rilski"11 WWANs: Wireless Wide Area Networks UseCellular phone communications networks (2G, 3G…) Standards GSM, GPRS, D-AMPS, UMTS, CDMA2000… Features Sophisticated encryption and authentication methods. Data transfers trough Packet-switched Data Networks (GPRS) or Circuit-switched dial-up connections. Speeds from 9.6 Kbps (GSM) up to 3.1 Mbit/s (CDMA2000)

12. UMG "St. Ivan Rilski"12 Conclusion? Only some questions from a young teacher How come my students are extremely active Internet users and do not want to know what the basics of Internet are? Why can’t I make them learn simple techniques in word processing in today but tomorrow they use a scanner, OCR software, and a spell checker in Bulgarian to print a reduced size text book for cheating at exams? How do I treat a person who takes pictures of the blackboard with his cellular telephone and distributes them among some others with a Bluetooth and IRDA? Why would anyone want to memorize anything since all he needs is a pocket-sized device?
