Bendrai nuotolinio švietimo sistemos analizei buvo naudojami norminių aktų, Lietuvos ir užsienio šalių mokslininkų darbų, publikuotų periodinėje spaudoje, ir įvairių Internetinių šaltinių, bibliotekinio tyrimo ir lyginamosios analizės metodai. Virtualioms mokymosi terpėms analizuoti buvo naudojami lyginamosios analizės ir eksperimentiniai tyrimo metodai. Virtualių universitetų koncepcijų tyrimui buvo taikoma sisteminė analizė, o virtualaus universiteto informacinei sistemai projektuoti, buvo naudotas koncepcinio modeliavimo metodas. Sistemos testavimui taikytas eksperimentinis metodas, o rezultatams apibendrinti – vertinamasis tyrimo metodas. / Modern Internet technologies have allowed new learning methods to appear for the realisation of which e-learning information technologies are created.

Šiuolaikiškas pasaulis su kiekviena diena keičiasi, tobulėja, pateikia vis naujus problemų sprendimo būdus. Švietimas įsipareigoja neatsilikti nuo naujovių, priimti besikeičiančio pasaulio iššūkius. Tokia padėtis daro įtaką ne tik ugdymo procesui ir jo organizavimui, bet žinoma ir visos švietimo įstaigos valdymui. Informacinės technologijos leidžia pateikti informaciją visuomenei apie jų vadovaujamą mokyklą internete, leidžia sudominti tuos, kurie nori mokytis jų ugdymo įstaigoje. To pasekoje atsiranda galimybės modernizuoti švietimo valdymą, gerinti mokyklų bendruomenių bendravimą. Besikeičiant švietimo įstaigoms, organizacinis ir administracinis darbas turėtų taip pat tapti šiuolaikiškesnis, kuriame būtų taikomos elektronin÷s priemonės ir metodai. Švietimo įstaigų vadovai tampa pagrindiniais dalyviais, iš kurių tikimasi naujovių diegimo ir palaikymo strategijos įgyvendinimas. Kitaip tariant mokyklai tampa reikalingas toks vadovas, kuris turi įgūdžių, sugebėjimų, žinių ir supratimą, kurių reikia įgyvendinant valstybinę strategiją mokykloje ir gerinant švietimo kokybę. Taip pat atsiranda būtinybė skatinti tobulinti informacines kompetencijas mokyklos vadovą, pagrindžiant informacinių technologijų galimybes, jų įtaką švietimo sistemai. Atsižvelgiant į tai, buvo iškelta problema – kokios yra bendrojo lavinimo mokyklų vadovų IT kompetencijos, kokie jų gebėjimai taikyti jas vadybinėje praktikoje, kokie galimi šių kompetencijų tobulinimo būdai. Tyrimo tikslas - ištirti bendrojo... [toliau žr. visą tekstą] / The modern world is changing every day, improving, give the new challenge. Education must keep pace with innovation, accept the challenges of a changing world.

Lietuvoje informacinių technologijų nuotolinėms studijoms teikiamą naudą tyrinėjo daug mokslininkų, tačiau apie pačias jų panaudojimo nuotolinėse studijose sutinkamas problemas, užsimenama nepakankamai. Siekiant išsamesnių duomenų šia tema, darbe iškelta tyrimo problema – kaip informacinės technologijos įtakoja nuotolinių studijų kokybę. Taip pat iškeliama hipotezė – informacinių technologijų plėtojimas skatina švietimo įstaigų teikiamų nuotolinių studijų kokybės gerinimą. Darbo tikslas – atlikti informacinių technologijų įtakos nuotolinių studijų kokybei tyrimą, atskleisti ir pagrįsti informacinių technologijų plėtros svarbą. Darbo tikslui pasiekti, įgyvendinti šie uždaviniai: 1) pagrįstos informacinių technologijų, nuotolinių studijų, studijų kokybės sampratos; 2) panaudojant statistinius duomenis, aptarta ir išanalizuota informacinių technologijų įtaka švietimui; 3) apibrėžta informacinių technologijų teikiama nauda nuotolinių studijų kokybei, atskleistos jų integravimo į švietimo procesą problemos; 4) panaudojant anketinę apklausą, atlikta informacinių technologijų įtakos nuotolinių studijų kokybės gerinimui analizė. Uždaviniams atlikti, pasirinkti metodai: 1) Dokumentų, statistinių duomenų pagal temą analizė (Lietuvos informacinės visuomenės plėtros strategija 2011- 2013 m, valstybės pažangos strategijos „Lietuva 2030“ projektas, Lietuvos ir užsienio mokslinių tyrimų statistika, Lietuvos statistikos departamento ir Pasaulio banko duomenys); 2) Edukologijos...

Informacinės technologijos ir Interneto tinklas įsiterpė į mokslą, gamybą, ekonomiką ir valstybės valdžią bei pakeitė mūsų pasaulėžiūrą – tai kas buvo neįmanoma dar prieš dešimtmetį, tapo realybė. Sąskaitų apmokėjimas Internetu, sutarčių pasirašymas, paslaugų užsakymas ir apsikeitimas kita informacija tarp privačių asmenų, valstybės institucijų ir verslo organizacijų vyksta „online“ (tiesioginio laiko) režimu. Tačiau kuo daugiau atsiranda naujų galimybių siunčiant duomenis Internetu, tuo sparčiau auga elektroninių nusikaltimų skaičius. Elektroniniai nusikaltėliai siekiant savanaudiškų tikslų gali pasinaudoti konfidencialia informacija, pakeičiant tik vieną simbolį, pavyzdžiui, sąskaitos numeryje ar kitaip iškraipant informaciją, gali atnešti nuostolių asmenims ir organizacijoms. Tačiau nepaisant visų grėsmių Interneto tinklas yra iki šiol greičiausiais, patogiausias ir populiariausias, tačiau nepatikimiausiais būdas siųsti duomenys , todėl reikėtų naudoti informacijos apsaugos priemones. / Information technologies and internet has interfered into science, production and government. Our world-view had definitely changed – what was impossible just a few years ago now became a reality. Paying bills by the internet, signing contracts, ordering services and exchanging information between private clients, governmental institutions and business organizations and other operation are making online. Number of electronic crimes rises directly proportionally to opportunities increasing in sending information by internet. Electronic criminals to suit their own aims can use confidential information by changing single symbol, for example in account number, or by distorting information in any other way may cause incur losses to users and organizations. However, despite of all the disadvantages, internet is the fastest, the most comfortable and popular, but the most insecure way to send information, that is the reason why we should use secure means of communication. The main object or this graduation thesis is explore digital signature as one of the newest secure means of communication . The main functions, usage singularity are analyzed in this work. Author direct attention to digital signature legal power which has been accepted by government. Digital signature is equivalence to hand-made signature. Also, have made an observation on cryptography’s (data coding) scientific methods for digital signatures functions ensuring. Separate part of work is divided to projects and... [to full text]
