A Peek Into the Standard Many in the e-Learning industry know that “AICC” is not only a standard… but also the committee that defines it. The AICC, Aviation Industry Computer-based training (CBT) Committee, was formed in 1988 by aviation manufacturers such as Boeing, Airbus, and McDonnell-Douglas to standardize the delivery of CBT at a time when multimedia training was becoming increasingly popular. And over the years, AICC implementations have spread to many other industries. AICC originally focused on local file-based operations. But in 1998, it expanded to include an HTTP/web-based interface known as HACP (pronounced “hack-P,” and which stands for HTTP-based AICC/CMI Protocol). Soon after, the standard was again updated to include a JavaScript run-time interface. And as a result, AICC courses worked in the growing number of e-Learning projects that operated across the web. Today, HACP is the most common type of AICC course in LMS e-Learning systems. Technically, AICC courses are defined using several files, which describe their content and structure. The files are generally known by their file extensions: CRS—This file contains information about the course as whole, such as its creator, title, description, and total number of lessons. AU—This file describes the course’s Assignable Units, which correspond to lessons in a non-AICC course. This data includes the names of the files that launch the lessons, each lesson’s mastery score, and the maximum time that students are allowed to take and pass the lessons. This file includes a file_name item that is actually a URL. See AICC Strengths for Today (below) for more about that. CST—This Course Structure file holds basic structural data, including a list of all AUs. And this list usually determines the order in which lessons are given to students. DES—ThisDescriptor file contains information about all course elements. The AICC standard defines three additional file types, but they aren’t used as often as the above. They are: Objectives Relationships (ORT), Prerequisites (PRE), and Completion Requirements (CMP). Installing an AICC Course Before students can take an AICC course through an LMS, the course must be installed on the LMS. The method differs between LMS systems, but typically goes like this: (1) The CRS course file is located and parsed. (2) A definition or shell is created in the LMS database for the course that’s listed in the CRS file. Any required course properties are also populated with values from the CRS file. (3) Similarly, course lessons are created in the LMS and the lesson properties are populated from the AU file. These lesson properties include the path to the lesson file, the lesson’s passing grade, and so on. It’s very important that the LMS system be able to overwrite an existing AICC course. Then, whenever the course is updated, simply re-installing it will deploy those changes on the LMS. AICC Strengths for Today Perhaps the AICC standard’s strongest feature for today’s e-Learning applications is its implementation of “Cross Domain Course Content.” This allows a course definition to exist on an LMS server, while the course content sits on a different (often remote) machine… even one located outside the LMS home network. This lets content providers keep their content on their servers, content that a remote LMS can call-up and display when students take the AICC course. The AICC standard accomplishes this by using a signed Java applet. Signing is critical because the web domain the course is launched from (the domain of the LMS) usually differs from the domain that the course content comes from. And an unsigned Java applet would see this difference as cross-site scripting, and reject it as a web attack. Here’s how Cross Domain Course Content works: (1) When a student launches an AICC lesson, the filename/URL in its AU file points to another internet (content) server. (2) Call-back information is sent to that remote content server, so that it knows which LMS server needs to communicate with it during the AICC course. (3) The remote content server then attempts to open a communication channel back to the LMS server that launched the lesson. (4) And once two-way communications are established, course content is can be pulled from the content provider’s location, through the LMS server, to the student PC. A Tool for Our Times and You The AICC standard has taken a number of years to reach today’s robust state. And Cross Domain Course Content makes it an ideal tool for distributed, global, training applications. But there have been so many revisions to the standard, that it’s still hard to know what an AICC-compliant LMS really is. LMS products can claim to be AICC-compliant, even when they support only the standard’s core features. As a result, it’s wise to delve into details when acquiring an AICC-compliant LMS! Another industry standard (SCORM) has also experienced strong growth. [See my article “SCORM and the Learning Management System (LMS)” (at http://www.syberworks.com/articles/scorm-and-the-lms-article.htm.] And as a result, AICC actually went out of vogue for a while. But it’s enjoying a resurgence, and its ability to support Cross Domain Course Content is largely responsible. So if you don’t need or want your LMS vendor to also host your course content, AICC may be just the tool for you. Aicc: Still A Viable Course Standard? A Peek Into the Standard

strong zavirite Standard / strong Mnogi u e-učenje industriju zna da je "AICC" nije samo standardni ... ali i odbor koji ga određuje. AICC, / strong viation I / strong ndustry C / strong omputer temeljene trening (CBT) C / strong ommittee, osnovana je 1988 od strane zrakoplovstva proizvođača kao što su Boeing, Airbus i McDonnell Douglas-standardizirati isporuku CBT u vrijeme kad multimedijske treninga je postajao sve popularniji. I tijekom godina, AICC implementacije koja su se proširila mnogim drugim industrijama. AICC izvorno fokusirana na lokalnim fascikl-baziran poslovanje. Ali u 1998, ona proširena na HTTP / web-temeljen sučelje poznato kao HACP (izgovara se "hack-P," a koje se zalaže za H / strong TTP-temeljen / strong ICC-a / C / strong MI P / strong rotocol). Ubrzo nakon toga, ponovno je standardni obnovljeno za uključiti JavaScript run-time sučelje. I kao rezultat toga, AICC tečajevi radio je u sve većem broju e-learning projekata, koje djeluju diljem weba. Danas, HACP je najčešći tip AICC tečaja u LMS e-Learning sustava. Tehnički, AICC tečajevi su definirani pomoću nekoliko datoteka, koje opisuju njihov sadržaj i strukturu. Datoteke su općenito poznati po svojoj ekstenzije datoteka: CRS- / strong Ova datoteka sadrži podatke o tijeku u cjelini, kao što njegov tvorac, naslov, opis, i ukupan broj sati. / strong AU- / strong Ova datoteka opisuje tijek / strong ssignable U / strong gnjide, koje odgovaraju sati u ne-AICC tečaja. Ovi podaci uključuju imena datoteka koje lansirati sati, svaki sat vještina bodova, a najviše vremena da se studenti smiju odslušati nastavu. Ova datoteka sadrži file_name predmet koji je zapravo URL. Vidi AICC prednosti za danas (dolje) za više o tome. CST- / strong Ova datoteka Struktura kolegija drži osnovnih strukturnih podataka, uključujući popis svih AUS. I ove liste se obično određuje redoslijed kojim se daju nastavu za studente. DES- / strong ThisDescriptor datoteka sadrži informacije o svim programskim elementima. AICC standard definira tri dodatne vrste datoteka, ali oni se ne koriste toliko često kao prije. To su: Ciljevi Odnosi (ORT / strong ), Preduvjeti ( PRE / strong ), a završetak Zahtjevi ( CMP / strong ). Instaliranje AICC Tečaj Prije nego što učenici mogu uzeti AICC pravac preko LMS, naravno, mora biti instaliran LMS. Metoda razlikuje između LMS sustava, ali se obično ide ovako: (1) / strong Datoteka CRS tečaj se nalazi i raščlaniti. (2) / strong definicija ili ljuska je kreirana u LMS bazu podataka za predmet koji je naveden u datoteci CRS. Bilo je potrebno naravno prostori su također naseljena s vrijednostima iz HRB-datoteku. (3) / strong Isto tako, naravno, lekcije su stvorene u LMS i sat prostori su naseljeni iz AU datoteke. Ti sat svojstva uključuju put do datoteke sat, sat je prolaznu ocjenu, i tako dalje. To je vrlo važno da LMS sustav biti u stanju prebrisati postojeće AICC tečaja. Zatim, kad god tečaj je obnovljeno, jednostavno re-instalacija će rasporediti one promjene na LMS. AICC prednosti za danas Možda AICC standardni je najjača osobina današnjih e-učenje programa je njegova implementacija "Cross Domena Tečaj sadržaja." Ovo omogućuje tečaj definicija postojati na LMS poslužitelju, a tečaj sadržaja sjedi na različitim (često udaljenog) stroj ... još jednom nalaze izvan mreže LMS kuće. To omogućuje pružateljima sadržaja držati njihov sadržaj na svojim serverima, sadržaj koji udaljenim LMS može nazvati-gore i prikazati kada učenici preuzimaju AICC tečaja. AICC standardni ostvaruje ovaj korištenjem Java applet potpisan. Potpisivanje je izuzetno važno jer domena tečaj je pokrenut od (domena LMS) obično se razlikuje od domene koje dolazi iz sadržaja kolegija. I nepotpisani Java applet će vidjeti tu razliku što je cross-site scripting, i to odbaciti kao web napada. Evo kako križ Domain Tečaj Sadržaj djela: (1) / strong Kada student pokreće AICC sat, ime datoteke / URL u svojoj datoteci AU ukazuje na još jedan Internet (sadržaja) poslužitelj. (2) / strong Call-Back podaci šalju tom udaljenom poslužitelju sadržaja, tako da se zna koja LMS poslužitelju treba komunicirati s njim tijekom AICC tečaja. (3) / strong udaljeni sadržaja Server potom pokušava otvoriti komunikacijski kanal natrag na LMS poslužitelju koji pokrenula sat. (4) / strong i jednom dvosmjerne komunikacije utemeljene, naravno, sadržaj može se izdvajali iz sadržaja davatelja lokaciji, putem LMS poslužitelju, kako bi učenik računalo. Alat za današnja vremena, a Vi AICC standardni je poduzela niz godina doći do današnje robustan stanje. I križ Domena Sadržaj kolegija čini ga idealnim alatom za distribuirane, globalno, trening programe. No, bilo je toliko revizijama standardu, da je još uvijek teško je znati što AICC-popustljiv LMS stvarno je. LMS proizvodi mogu tvrditi da AICC-popustljiv, čak i kad se podržavaju samo standardne jezgre značajke. Kao rezultat toga, svoj 'mudar to zadubiti u detalje pri stjecanju AICC-popustljiv LMS! Drugi industrijski standard (SCORM) također je doživio snažan rast. [Vidi moj članak "SCORM i sustava za upravljanje učenjem (LMS)" (na http://www.syberworks.com/articles/scorm-and-the-lms-article.htm / strong .] I kao rezultat toga, AICC zaista ode iz Voguea za neko vrijeme. Ali to je uživajući preporod, a njegova sposobnost to podrška križa Domena Sadržaj kolegija je u velikoj mjeri odgovoran. Dakle, ako ne trebate ili želite da se vaše LMS dobavljača da također ugostiti svoje tečaja sadržaj, AICC svibanj biti samo alat za vas.
