Unit 7 Educational Multimedia Educational multimedia Unit 7 Unit 7 Educational multimedia What is multimedia? Multimedia can mean many different things. Taken literally, the term multimedia really only means to communicate in more than one way. Jumping up and down while singing praise for the winning rugby team is providing onlookers around you a multimedia presentation (movement + sound). In education multimedia might be the presentation of line graphs with an overhead projector to support the oral delivery of an economics lesson. It could be using e- mail to supplement communication in a face-to-face group-work activity. Students downloading and revisiting audiotaped lessons on their iPods are using a form of multimedia to reinforce what they have been assigned to read in their course textbook. According to Wikipedia, „multimedia is the use of several different media (eg text, audio, graphics, animation, video, and interactivity) to convey information.‟ Educational multimedia is understood to be multimedia which provides learning resources by using a variety of media in an integrated way for the purpose of instruction. By doing so we provide resources to students in ways that best suit their learning needs and capture their interest. This chapter will provide: An overview of the main types of educational multimedia A rationale for the use of multimedia in teaching including examples and Good practice guidelines. 1.0 Why use multimedia? Incorporating multimedia into teaching requires extra time and effort – so, really, why even bother? The case for multimedia in education is quite simply an enhanced learner experience. If implemented thoughtfully multimedia can facilitate a richer learning experience and promote deeper understanding. Using multimedia also supports students with different preferences for how information is presented. In other words two formats for presentation are better than one (Mayer, 2009). Pictures convey information more quickly than words. Virtual worlds enable learners to actively participate in authentic tasks, empowering them to do things in an environment that provides a level of complexity and information representative of the actual setting rather than be passive onlookers. Interactive animations can create more exciting and captivating learning experiences. Students can choose, start and stop simulations at their own pace. They can view and scrutinise images as often as they like, repeat practice quizzes or audiotaped lessons for clarification of topics. Presenting information by using more than one format © Edinburgh Napier University 105 Unit 7 Pedagogy and learning technology: a practical guide caters to the different ways in which students learn. In addition by providing more than one way for students to gain information we are improving accessibility. Unfortunately, the past has seen many inappropriate uses of multimedia in teaching due to a preoccupation with the technology rather than with the learner. Technologically dazzling multimedia has rarely lived up to the expectations of its creators and has hardly influenced the learning process or transformed practice or effectiveness of teaching. When considering multimedia for teaching the aim must not be to showcase cutting-edge technology, but rather to adapt technology to enhance the student learning experience. A range of stunning animations created to deliver vast quantities of information can easily become distracting, whereas one semi-interactive tutorial has the potential of maintaining attention while helping consolidate knowledge and skills introduced to the learner elsewhere. 1.1 When to use multimedia Some subject areas lend themselves seemingly naturally to the incorporation of multimedia. Contemporary lessons in art design have never been only text-based, of course. Chemistry students benefit hugely in their spatial understanding from building and manipulating 3D computer graphic models of molecules (eg Figure 19) and are better prepared for actual quantitative analysis by calculating appropriate concentrations of reactants in virtual lab experiments. The health field sees everything from heart sound tutorials to digestion video clips support understanding and provide opportunity to practice key skills. But how might English as a second language, history, law or business studies benefit? Let‟s explore just a few examples which might give you an idea or two of your own. Case Study Doris, a French studies tutor, is frustrated by the poor aural comprehension skills of her students. She feels limited in what she can do to support them better given the sheer number of students and a bare minimum of contact hours with them. After consulting the faculty‟s online learning adviser she feels encouraged to create weekly audio- introductions to lessons online in addition to uploading written lecture notes. Using freely available audio recording software she records weekly lesson outlines but soon adds announcements and „phrases of the day‟ to the VLE for students to correctly translate in the following face-to-face lecture. Doris has not only incorporated multimedia meaningfully into her teaching but has managed to link online activity directly to the face-to-face lecture adding relevance and purpose to both. Her students are pleased about the additional and flexible opportunity to refine their listening skills. Now is the time to reflect on your teaching and ask yourself: Is there a complex process you would like your students to see? Are there problem-solving skills your students need more opportunities to practice? 106 © Edinburgh Napier University Educational multimedia Unit 7 Do your students need to become better prepared for labs or for workplace related assignments? Have you considered the benefits of engaging your students in an otherwise inaccessible authentic environment (such as on the moon, at the bottom of the ocean)? Would your students benefit from more interactive self-assessment opportunities? Have you been thinking about making your students feel more comfortable learning online? If your answer to only one of the questions above was yes, then you may very well find that a form of multimedia could enhance your students‟ learning experience. 2.0 Educational multimedia technology Let‟s take a look at some of the most frequently used technologies and review key educational benefits of incorporating these into your teaching. Through examples you will see how each might be used to accomplish a specific learning outcome defined beforehand for that particular multimedia application. The main elements of multimedia applications include graphics, video, audio, animations and interactive technologies, which are described below. Also find a short introduction to the emerging technologies of m-learning, wireless technologies, podcasting, augmented realities and educational gaming.

Object analysis is enabled. 2.1.2 Teaching example Writing composition students are sent to pick one painting of their choice by Paul Cezanne at http://www.ibiblio.org/wm/paint/auth/cezanne/ and describe it in a written essay. 2.1.3 Web resources for graphics SCRAN at http://www.scran.ac.uk/ (Edinburgh Napier subscription) JISC BIO Science Image Bank at http://www.bioscience.heacademy.ac.uk/imagebank/ Flickr at http://flickrcc.bluemountains.net/ 2.1.4 Implementation tips To save an image, right click on it with your mouse and click on „save image as‟ Download Picasa from http://picasa.google.com/ to find and organise all your pictures on your PC. Use Picnik at http://www.picnik.com for easy editing 2.2 Video Video refers to the „technology of capturing, recording, processing, transmitting, and reconstructing moving pictures‟ (definition in Wikipedia at http://en.wikipedia.org/wiki/Main_Page). 2.2.1 Benefits of video Portrays authentic learning situations enhancing the authenticity of computer- based learning environment; presents scenarios otherwise inaccessible to traditional classroom (operating theatre, historic landmark etc). 2.2.2 Teaching example Link a descriptive video clip to a written paragraph about the shortage of potable water in Lesotho (eg countries around the world video clips at http://www.peacecorps.gov/wws/multimedia/videos/ 2.2.3 Web resources for video Visit the Moving Image Gateway (MIG) for educational video and audio resources at http://www.bufvc.ac.uk/gateway/ 108 © Edinburgh Napier University Educational multimedia Unit 7 HERMES is the British Universities Film & Video Council‟s (BUFVC) central database at http://www.jisc- collections.ac.uk/catalogue/coll_hermes EMOL (Education Media Online) database with over 300 hours of film related to every subject area at http://bufvc.ac.uk/ (completion of licence agreement required) 2.2.4 Implementation tips Use Viddler (http://www.viddler.com/) or Vimeo (http://vimeo.com/) to create video presentations yourself.

  • Network Requirements for High-Speed Real-Time Multimedia
    NETWORK REQUIREMENTS FOR HIGH-SPEED REAL-TIME MULTIMEDIA DATA STREAMS Andrei Sukhov1), Prasad Calyam2), Warren Daly3), Alexander Iliin4) 1) Laboratory of Network Technologies, Samara Academy of Transport Engineering, Samara, Russia 2) Department of Electrical and Computer Engineering, Ohio State University, Ohio USA 4) HEANet Ltd, Dublin, Ireland 4) Russian Institute for Public Network, Moscow, Russia Abstract High-speed real-time multimedia applications such as Videoconferencing and HDTV have already become popular in many end-user communities. Developing better network protocols and systems that support such applications requires a sound understanding of the voice and video traffic characteristics and factors that ultimately affect end-user perception of audiovisual quality. In this paper we attempt to propose an analytical model for the various network factors whose interdependencies need to be modeled for characterizing end- user perception of audiovisual quality for high-speed real-time multimedia data streams. Towards validating our theory presented in this paper, we describe our initial results and future plans that consist of conducting a series of experiments and potential modifications to our proposed model. As the portion of middle and high-speed RTP (Real-Time Protocols) applications in the total communication over the Internet grows, it is important to understand the behavior of such traffic over the TCP/IP networks. The impetuous growth of traffic volumes and the rapid advances in the technologies of new-generation networks like IPv6 have made it possible for use of such high-speed applications, but with new demands on the network to deliver superior Quality of Service (QoS) to these applications. Our research focuses on the area of quality criteria for middle and high-speed network applications like • Video Conferencing / Streaming • Grid applications • P2P applications Audio- and Videoconferencing are two major multimedia communications that are defined by various international standards such as H.320, H.323 and SIP.

Education is at the confluence of powerful and rapidly shifting educational, technological and political forces that will shape the structure of educational systems across the globe for the remainder of this century. Many countries are engaged in a number of efforts to effect changes in the teaching/learning process to prepare students for an information and technology based society. Multimedia provide an array of powerful tools that may help in transforming the present isolated, teacher-centred and text-bound classrooms into rich, student-focused, interactive knowledge environments. The schools must embrace the new technologies and appropriate multimedia approach for learning. They must also move toward the goal of transforming the traditional paradigm of learning. Teacher education institutions may either assume a leadership role in the transformation of education or be left behind in the swirl of rapid technological change. For education to reap the full benefits of multimedia in learning, it is essential that pre-service and in-service teachers have basic skills and competencies required for using multimedia.

  • Lecture 11 : Discrete Cosine Transform Moving Into the Frequency Domain
    Lecture 11 : Discrete Cosine Transform Moving into the Frequency Domain Frequency domains can be obtained through the transformation from one (time or spatial) domain to the other (frequency) via Fourier Transform (FT) (see Lecture 3) — MPEG Audio. Discrete Cosine Transform (DCT) (new ) — Heart of JPEG and MPEG Video, MPEG Audio. Note : We mention some image (and video) examples in this section with DCT (in particular) but also the FT is commonly applied to filter multimedia data. External Link: MIT OCW 8.03 Lecture 11 Fourier Analysis Video Recap: Fourier Transform The tool which converts a spatial (real space) description of audio/image data into one in terms of its frequency components is called the Fourier transform. The new version is usually referred to as the Fourier space description of the data. We then essentially process the data: E.g . for filtering basically this means attenuating or setting certain frequencies to zero We then need to convert data back to real audio/imagery to use in our applications. The corresponding inverse transformation which turns a Fourier space description back into a real space one is called the inverse Fourier transform. What do Frequencies Mean in an Image? Large values at high frequency components mean the data is changing rapidly on a short distance scale. E.g .: a page of small font text, brick wall, vegetation. Large low frequency components then the large scale features of the picture are more important. E.g . a single fairly simple object which occupies most of the image. The Road to Compression How do we achieve compression? Low pass filter — ignore high frequency noise components Only store lower frequency components High pass filter — spot gradual changes If changes are too low/slow — eye does not respond so ignore? Low Pass Image Compression Example MATLAB demo, dctdemo.m, (uses DCT) to Load an image Low pass filter in frequency (DCT) space Tune compression via a single slider value n to select coefficients Inverse DCT, subtract input and filtered image to see compression artefacts.

The field of digital images compression becomes an important field of digital images processing fields due to the need to exploit the available storage space as much as possible and reduce the time required to transmit the image. Baseline JPEG Standard technique is used in compression of images with 8-bit color depth. Basically, this scheme consists of seven operations which are the sampling, the partitioning, the transform, the quantization, the entropy coding and Huffman coding. First, the sampling process is used to reduce the size of the image and the number bits required to represent it. Next, the partitioning process is applied to the image to get (8×8) image block. Then, the discrete cosine transform is used to transform the image block data from spatial domain to frequency domain to make the data easy to process.

  • An Overview of Multimedia Content Protection in Consumer Electronics Devices
    An overview of multimedia content protection in consumer electronics devices Ahmet M. Eskicioglu* and Edward J. Delp‡ *Thomson Consumer Electronics Corporate Research 101 W. 103rd Street Indianapolis, Indiana 46290-1102 USA ‡ Video and Image Processing Laboratory (VIPER) School of Electrical and Computer Engineering Purdue University West Lafayette, Indiana 47907-1285 USA ABSTRACT A digital home network is a cluster of digital audio/visual (A/V) devices including set-top boxes, TVs, VCRs, DVD players, and general-purpose computing devices such as personal computers. The network may receive copyrighted digital multimedia content from a number of sources. This content may be broadcast via satellite or terrestrial systems, transmitted by cable operators, or made available as prepackaged media (e.g., a digital tape or a digital video disc). Before releasing their content for distribution, the content owners may require protection by specifying access conditions. Once the content is delivered to the consumer, it moves across home the network until it reaches its destination where it is stored or displayed. A copy protection system is needed to prevent unauthorized access to bit streams in transmission from one A/V device to another or while it is in storage on magnetic or optical media. Recently, two fundamental groups of technologies, encryption and watermarking, have been identified for protecting copyrighted digital multimedia content. This paper is an overview of the work done for protecting content owners’ investment in intellectual property. Keywords: multimedia, copy protection, cryptography, watermarking, consumer electronics, digital television, digital video disc, digital video cassette, home networks. 1. INTRODUCTION In the entertainment world, original multimedia content (e.g., text, audio, video and still images) is made available for consumers through a variety of channels.
