<P> Some educational software is designed for use in school classrooms . Typically such software may be projected onto a large whiteboard at the front of the class and / or run simultaneously on a network of desktop computers in a classroom . This type of software is often called classroom management software . While teachers often choose to use educational software from other categories in their IT suites (e.g. reference works, children's software), a whole category of educational software has grown up specifically intended to assist classroom teaching . Branding has been less strong in this category than in those oriented towards home users . Software titles are often very specialized and produced by various manufacturers, including many established educational book publishers . </P> <P> With the impact of environmental damage and the need for institutions to become "paperless", more educational institutions are seeking alternative ways of assessment and testing, which has always traditionally been known to use up vasts amount of paper . Assessment software refers to software with a primary purpose of assessing and testing students in a virtual environment . Assessment software allows students to complete tests and examinations using a computer, usually networked . The software then scores each test transcript and outputs results for each student . Assessment software is available in various delivery methods, the most popular being self - hosted software, online software and hand - held voting systems . Proprietary software and open - source software systems are available . While technically falling into the Courseware category (see above), Skill evaluation lab is an example for Computer - based assessment software with PPA - 2 (Plan, Prove, Assess) methodology to create and conduct computer based online examination . Moodle is an example of open - source software with an assessment component that is gaining popularity . Other popular international assessment systems include Assessment Master, QuestionMark, EvaluNet XT and QuestBase . </P> <P> Many publishers of print dictionaries and encyclopedias have been involved in the production of educational reference software since the mid-1990s . They were joined in the reference software market by both startup companies and established software publishers, most notably Microsoft . </P> <P> The first commercial reference software products were reformulations of existing content into CD - ROM editions, often supplemented with new multimedia content, including compressed video and sound . More recent products made use of internet technologies, to supplement CD - ROM products, then, more recently, to replace them entirely . </P>
