Online Video Presentations
Presentation programs for preparing and delivering online video presentations have a place in educational instruction. They enable presentation of teaching materials in the form of a slide show or as a screencast. Among such packages Microsoft PowerPoint is the most widely used in instructional contexts. The live instructor retains a vital role in delivering the presentation. Features of MS PowerPoint MS PowerPoint has become the dominant presentation tool because it is both readily available and easy for instructors to use (Grabe & Grabe 2007). It allows instructors to create and manipulate presentations in a wide variety of contexts that can enhance student’s interest and engagement (Mills & Roblyer, 2006). In addition, it helps instructors clearly identify the main points of a topic or activity while still providing the details through presentation (Loisel & Galer, 2004). Instructors can incorporate multiple types of media formats (e.g., diagram, photo, drawing, sound and vid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Presentation Program
A computing, a presentation program (also called presentation software) is a software package used to display information in the form of a slide show. It has three major functions: * an editor that allows text to be inserted and formatted * a method for inserting and manipulating graphic images and media clips * a slide-show system to display the content Presentation software can be viewed as enabling a functionally-specific category of electronic media, with its own distinct culture and practices as compared to traditional presentation media (such as blackboards, whiteboards and flip charts). Presentations in this mode of delivery have become pervasive in many aspects of business communication, especially in business planning, as well as in academic-conference and professional conference settings, and in the knowledge economy generally, where ideas are a primary work output. Presentations may also feature prominently in political settings, especially in workplace politic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Education
Education is a purposeful activity directed at achieving certain aims, such as transmitting knowledge or fostering skills and character traits. These aims may include the development of understanding, rationality, kindness, and honesty. Various researchers emphasize the role of critical thinking in order to distinguish education from indoctrination. Some theorists require that education results in an improvement of the student while others prefer a value-neutral definition of the term. In a slightly different sense, education may also refer, not to the process, but to the product of this process: the mental states and dispositions possessed by educated people. Education originated as the transmission of cultural heritage from one generation to the next. Today, educational goals increasingly encompass new ideas such as the liberation of learners, skills needed for modern society, empathy, and complex vocational skills. Types of education are commonly divided into formal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slide Show
A slide show (slideshow) is a presentation of a series of still images (Presentation slide, slides) on a projection screen or electronic display device, typically in a prearranged sequence. The changes may be automatic and at regular intervals or they may be manually controlled by a presenter or the viewer. Slide shows originally consisted of a series of individual reversal film, photographic slides projected onto a screen with a slide projector. When referring to the video or computer-based visual equivalent, in which the slides are not individual physical objects. A slide show may be a presentation of images purely for their own visual interest or artistic value, sometimes unaccompanied by description or text, or it may be used to clarify or reinforce information, ideas, comments, solutions or suggestions which are presented verbally. Slide shows are sometimes still conducted by a presenter using an apparatus such as a carousel slide projector or an overhead projector, but now ...

Screencast
A screencast is a digital recording of computer screen output, also known as a video screen capture or a screen recording, often containing audio narration. The term ''screencast'' compares with the related term ''screenshot''; whereas screenshot generates a single picture of a computer screen, a screencast is essentially a movie of the changes over time that a user sees on a computer screen, that can be enhanced with audio narration and captions. Etymology In 2004, columnist Jon Udell invited readers of his blog to propose names for the emerging genre. Udell selected the term "screencast", which was proposed by both Joseph McDonald and Deeje Cooley. The terms "screencast" and "screencam" are often used interchangeably, due to the market influence of ScreenCam as a screencasting product of the early 1990s. ScreenCam, however, is a federal trademark in the United States, whereas screencast is not trademarked and has established use in publications as part of Internet and computi ...

Microsoft PowerPoint
Microsoft PowerPoint is a presentation program, created by Robert Gaskins and Dennis Austin at a software company named Forethought, Inc. It was released on April 20, 1987, initially for Macintosh computers only. Microsoft acquired PowerPoint for about $14 million three months after it appeared. This was Microsoft's first significant acquisition, and Microsoft set up a new business unit for PowerPoint in Silicon Valley where Forethought had been located. PowerPoint became a component of the Microsoft Office suite, first offered in 1989 for Macintosh and in 1990 for Windows, which bundled several Microsoft apps. Beginning with PowerPoint 4.0 (1994), PowerPoint was integrated into Microsoft Office development, and adopted shared common components and a converged user interface. PowerPoint's market share was very small at first, prior to introducing a version for Microsoft Windows, but grew rapidly with the growth of Windows and of Office. Since the late 1990s, PowerPoint ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LCD Projector
An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector. To display images, LCD (liquid-crystal display) projectors typically send light from a metal-halide lamp through a prism or series of dichroic filters that separates light to three polysilicon panelsone each for the red, green and blue components of the video signal. As polarized light passes through the panels (combination of polarizer, LCD panel and analyzer), individual pixels can be opened to allow light to pass or closed to block the light. The combination of open and closed pixels can produce a wide range of colors and shades in the projected image. Metal-halide lamps are used because they output an ideal color temperature and a broad spectrum of color. These lamps also have the ability to produce an extremely large amount of light within a small area; current projectors average ...

Presentation Slide
A slide is a single page of a presentation. Collectively, a group of slides may be known as a slide deck. A slide show is an exposition of a series of slides or images in an electronic device or in a projection screen. Before the advent of the personal computer, a presentation slide could be a 35 mm slide viewed with a slide projector or a transparency viewed with an overhead projector. In the digital age, a slide most commonly refers to a single page developed using a presentation program such as MS PowerPoint, Apple Keynote, Google Slides, Apache OpenOffice or LibreOffice. It is also possible to create them with a document markup language, for instance with the LaTeX class Beamer. Lecture notes in slide format are referred to as lecture slides, frequently downloadable by students in .ppt or .pdf format. Slide producing software Presentation slides can be created in many pieces of software such as Microsoft PowerPoint, Apple Keynote, LibreOffice Impress, Prezi, ClearSlide ...
