Post-It Note!

 My blog consists of daily journal entries. The newest journal entries are the main questions first. As for the other journal entries consists of problems/solutions and ideas/issues ( the older posts). Due to the blog being from latest to oldest , the oldest post, would be my very first blog entry and would be the introduction to the assignment!

Another Note:


Update: I just want to note something. Since we already submitted our website on the 1st of July 2011, our Prezi presentation was also submitted. For none of the transmission media, were we unable to find the 'security' part of the question. So before our blog was due, I was looking on the useful links on our student net and I actually found the answer. So I thought I would reference it here:

Security -  Wired (twisted pair, coaxial cable, optic fibre):
  • For wired Local Area Networks - firewalls are the main security. They can be installed on the computer.
  • Thus as the wired transmissions are connected to the computer, they are then connected to the Internet, with firewalls acting as security.
Security- Wireless (microwave, satellite, radio, infra-red):
  • Less secure than wired.
  • Signals "travel through the air and can be easily intercepted."
  • Yet there is Wired Equivalent Privacy (WEP)  encryption standard, which protects data of Wireless Local Area Networks.

Discussion of file formats used in your information system. Justify your use of these formats

Discuss: Identify issues and provide points for and/or against.
There were various file formats that were used within the information system for the multimedia presentations that were created. This included:
  • jpeg: This format was used for most of the images on the hypermedia website. It was easy to manipulate and edit without the actual quality of the image being affected (pixelated).Furthermore the "degree of compression can be adjusted allowing a selectable tradeoff between storage size and image quality". Moreover this format was also used for the background images on the web pages, which were clear. This format was also used for the images which matched the corresponding information, and when it came to adjusting the images to the same size, it stayed clear and was easy to adjust. In terms of file size, jpeg images did not take too much storage space, enabling more storage space for the web pages and videos. Yet a disadvantage to this is, as JPEG loses quality and information every time it is saved.
  • png (portable network graphics image): This was used for the logo used within our newsbroadcast video. The logo was created on Microsoft Publisher. As it was used within the newsbroadcast video in every slide, it had to be adjusted to a smaller size. Once done, the image was still clear and the image quality was left unaffected.


  • m4a: This is an audio file, that was on iTunes. It was the original format for the background music use for the web pages. When the background music (with this format) was originally placed on the web page, it did not work. Thus it had to be converted to another appropriate file format. The songs required were only in this file format, and so it was vital that they were converted if used. Yet a problem had occurred, as it was converted online, the converting of a file did not work, so the song had to be looked up on Youtube, and converted accordingly.
  • wav: This is an audio file. The background music used on the first web page was converted from m4a to wav. Even though the .m4a file was renamed to .wav, obviously this still did not work. So it was converted online by media converter to .wav file ( using a youtube video of the same song). The reason that it was converted to this particular file format, was because in a previous website created by the team, the background music was in this particular file format. 
  • m4v: This is a video format, which was used for the welcome video, the newsbroadcast video and the bloopers video. This was the default format for the video when edited on iMovie (Apple application). The video worked and was clear & of good quality, even when it was uploaded onto Sharepoint Designer (which is a Microsoft application). Furthermore when uploaded onto the web page, the video was using Quick Time player to display the video.
  • ppt: This is a powerpoint presentation. It is the format used for the p.p. on the question of emerging trends (blogs), for the storyboards (website and video on Google Documents) as well as for the Network Topologies question. As the powerpoint presentation was unable to be viewed on the web pages, SlideShare which used the same file format ,uploaded the presentation, and was able to be embedded within the web page. 
  • doc: This is a word document. The downloadable links for the question on transmission media page, is a word document ( for the crossword questions and answers). It enables the student to print out the document. Any person with a computer, who clicks on the downloadable link, will be able to save or open the file and view the document. It is an extremely common file format.
  • html: This is web page. It was the default/common format, for the web pages created on Sharepoint Designer. All the web pages were saved in this file format and opened up in any web browser (Internet Explorer, Safari, Firefoz etc….).

Discussion of environmental factors (as defined by ISC) that influenced the design of this multimedia system for the given context, and ways your team addressed them

Discuss: Identify issues and provide points for and/or against.
 The information system's environment,  influences and is influenced by the school environment. In saying this within this environment are year 12 students, teachers and parents . As for outside the school environment is also web designers. Thus they pose as environmental factors that have influenced the design of the multimedia system. Furthermore there were a number of ways, our team had addressed such factors.
  • Year 12 students (part of the school environment): The design of the information system- the website was catered for the educating of year 12 students studying Communication Systems according to the syllabus. As the main objective of this assignment was to "create a hypermedia tutorial that could be used to instruct year 12 students on various aspects of Communication Systems as outline in the year 12 syllabus", the website had to cater to the needs of the students. It had to include a number of tools that not only allowed students to learn effectively but enhance their knowledge accordingly.It had to be user friendly and enable them to navigate through each page with ease, gaining knowledge from each resourceful tool. Thus the way that year 12 students learnt and understood was taken into account and influenced the design of the multimedia tutorial.     Furthermore, my team and I addressed this, by creating a multimedia website, that did not have only summarised text on each page, that didn't satisfy the various learners (such as visual learners). Instead we had multimedia aids that were entertaining and allowed for the students to easily understand the content of the question. For example, instead of creating a powerpoint and providing a downloadable link, we used Prezi. Which was an enhanced version of a powerpoint, but was a 'zooming presentation'. It incorporated multiple features such as zooming in on images, text and video rather than the simple transitions on Microsoft Powerpoint. We also embedded the presentation so students were just a click away from viewing it. Also another example, was the news broadcast video we created for the question on error detection, which had summarised information on the bottom of the webpage ( in bullet points). The video, was not only entertaining but gave a case study on where error detection can occur. Other various aspects that our team had applied, included background music and the background image on the welcome page. Which gives immediate attraction to the website making the student wanting to enter. Moreover we also included activities, such as the crossword for the question on transmission media, to allow students to gain knowledge from different ways of learning. The storytelling animation is another way that our team had addressed the environment factors. Another key feature was the tips and tricks page which caters for year 12 students, giving tips on coping with the HSC using appropriate study techniques. Overall, through the use of images, videos, colourful text was the way our team had addressed the needs year 12 students. Thus they had a great influence on the designing of the hypermedia tutorial.
  • Teachers (part of the school environment): The information system- the website was also designed in such a way so as to provide tools for teachers to educate year 12 students on Communication Systems according to the syllabus. As the hypermedia tutorial was created for use by year 12 students studying Communication Systems, teachers are also an indirect source of receiving the information. In saying this, if teachers find the website effective and helpful in teaching their students about the topic, then they can not only use the website to teach the students but also recommend them to the website. Through the various aids such as videos, activities, colourful text and image, our team has addressed this environmental factor.
  • Parents (part of the school community): The information system- the website was designed in such as way so as to enable parents to know their child is learning the specific topic according to the year 12 IPT syllabus. Once again, through the various learning aids that encompasses aspects of multimedia, our team had addressed the expectation of parents. In saying this, if parents are reviewing the work being done by their child, through looking at the resources they are using, the hypermedia tutorial in the form of a website, can meet their expectations  and show that their child is learning effectively.
                                            Prezi- The Zooming Presentation.
                                           Videos- a helpful learning tool.
     A storytelling animation ( uploaded on Youtube by one of the team members)- a helpful learning tool.
                                          A powerpoint presentation- just a click away.
                                          Colourful text- a useful aid.
  • Web designers: Have also influenced the designing of the information system- the website as they ensure the social and ethical factors of developing the multimedia tutorial website. That is not only effective in teaching year 12 students, but is also relevant to the use by teachers. In saying this, our team ( being the web designers) have addressed this, through the inclusion of a terms and conditions page. Which requires the users to agree ( or disagree) to the use of the website and its content. Moreover, if users have no internet access at home (equality) to view the hypermedia tutorial, particular aspects of the website have downloadable links to open to documents (crosswords, tips and tricks which are printable, a study timetable template ) and powerpoint presentations. In saying this, another person can give the student without internet access a copy of the documents, allowing them to utilise some of the aids by the website. Yet as they are year 12 student, internet access can be available at their school, allowing them to then utilise all of the aids provided by the website.
                                Terms and Conditions of using the website.

                  A link that can be downloaded, saved on a USB and given to a student without internet access.

Critical evaluation of the effectiveness of a similar multimedia package within the context for which it has been designed

Evaluate: Make a judgment based on criteria; determine the value of.
 Betts Computers- A similar multimedia package which is within the context for which it has been developed. This site covers all the topics of the year 12 IPT syllabus. Thus including a comprehensive description on Communication Systems. Below is an evaluation of the website- weighing the positives and negatives of this multimedia package.
                   Betts Computer- Clear links ( a pro) but there is too much happening on one page ( A con).

 The Pro's

  •  Covers all areas of the year 12 IPT syllabus ( can be seen from the navigational menu).
  • A webpage dedicated to an introduction to communication systems. This is a great way in establishing the content of the topic. Thus allowing the user to gain knowledge on the basics of communication systems. It also has useful images/diagrams.

A useful labelled diagram.
  • There is also a page called the 'Communications Glossary'- which can be extremely helpful in allowing the users to looks up certain words they don't understand . Yet this webpage is a broken link, and cannot be accessed!
  • Clear links to each page- a good navigational menu. Furthermore it is colourful, which is appealing to the user.
  • On most of the webpages that can be accessed, there is a little box with keywords in it. This is a helpful tool for the user to remember the keywords when it comes to learning the content.
  • The use of images/diagrams to support information: Allowing the users to understand the information more, and useful for visual learners.
                                                                 Diagrams help support information.
  • Examples are provided. This can enable the user to understand the information more, if they have examples to apply the information to.

The Con's

  • The main webpage is too cluttered. Meaning that it is not too appealing to the visitor initially, there is too much text and links (image above).
  • Broken links. Some of the webpages do not display. Thus can effect the user's impression of the website. Especially if the user relies on the website for their information and part of it is unable to be accessed.
  • There are no videos, powerpoint presentations, or downloadable links: These are quiet helpful learning tools, which summarises and provides a new way to display information and allow users to gain knowledge. Thus the website lacks such helpful learning aids.
  • There are no activities: Such activities could include a find-a-word, or a crossword, anything that would make the content more fun to learn about and understand.
  • Some of the webpages, have too much text and no images/diagrams at all. This can bore certain users, who learn effectively through images/diagram as well. Furthermore the text is not in bullet points, which can help summarise information and allow users to understand more effectively in short, concise sentences.
                                              Too much text.

 Overall Betts Computers - a multimedia package, is quite an informative and good source of information for the year 12 IPT syllabus- more specifically on Communication Systems. Yet if some of the broken links are fixed, this would be increase the usefulness of the website!

Outline the information technology used in creating digital content for the information system

Outline: Sketch what may happen based on available information.
 Within this assignment, there were a number of software and hardware devices that were used in creating digital content for the information system.

Software:
  • Microsoft Sharepoint Designer 2007: This was used for the creation of the website. It enabled multiple web site pages to be created, with the associated content ( music, text, videos, downloadable links).
  • Microsoft Publisher: This was used for the creation of the RSS logo, which was included within the news broadcast video. 
  • Microsoft Powerpoint/ Microsoft Word: M.P was used for the creation of the powerpoint on the question of emerging trends (blogs). It allowed for the creation of multiple slides which included text and images.
  • Inkscape: This was used for the editing of the background image on the emerging trend (blogs) question. It allowed for the modification of the brightness/contrast of the image. Thus as the original background was too dark, and the associated text would not be seen, this software allowed for the a lighter background.
  • Prezi: This was used for the creation of the 'zooming presentation', for the question on Transmission Media. It allowed a new way, for the understanding and learning of information.
  • iMovie: This was used for the editing of all the videos, created by the team. It was used for the welcome video, the news broadcast video, and the bloopers video.It allowed music to be added, transitions and other various aspects to be added to the video.
  • Windows Movie Maker: This was used for the creation of the video, which was used within the News broadcast video itself.
  • Audacity: This was used for the editing of sound in the Network Topologies video. It allowed for the modification of the tone of the speaker voice within the video.
  • Media Converter: (online) was used for the converting of m4a audio files to wav audio files. As the original audio files (for the background music) were unable to be played on the web page, media converter enables a Youtube URL to be entered, a specific file format to be selected and converts it to that file format.It also allowed for an audio file to be selected and converted, but this unfortunately did not work.
  • Quizlet: This was used for the creation of flashcards online, for the tips and tricks website page. It allowed for the screenshots of each flashcard on the page. Furthermore the website (Quizlet) was placed as a link on the Hypermedia website, for the student to visit and print out the flashcards for their own use.
  • Google Docs: This was used as an extremely helpful tool for each of the group members, to share various documents on the assignment ( for example: the storyboard for the website) and communicate with one another. 
Hardware:
  • Computer: Without this piece of hardware, there would be no assignment! It was essential for everything, right from the creation of the website, to the sharing of documents ( through accessing of the Internet) to the editing of the videos and so on. 
  • Camera ( iPhone): This piece of hardware was used for the recording of all the videos ( the welcome video and the news broadcast video. It gave clear resolution and sound for the video.
  • Speaker: This enabled sound to be heard in the videos and for the background music. 
  • Microphone: This was used for the recording of the sound for the Network Topologies video.
  • Headphones:This was used for hearing the sound for the videos, and the background music during class time.
  • Projector: This was used during the news broadcast video, as it enabled the video behind the news reader to be displayed. 
  • USB: This was an essential piece of hardware. As it allowed for all the work within the assignment to be saved and used anywhere at any time.

Screen Capture Video

 As mentioned in one of the previous posts,  we had decided not to complete the interactive video. Instead we decided to complete a screen capture video. This involved creating a powerpoint presentation and adding audio over it. The audio was recorded by one of our group members- Reshma. Then this audio file was edited on Audacity, in order to change the tone of the voice. Then being converted into a video- a .wmv file.
 There was a slight problem with this video when embedded onto the website.  The video was originally sent to my email address. When it opened, it only went for 4 seconds and stopped abruptly. Even though the whole length of the time written was around 4 minutes. So, as one of our team members, already had an account with Youtube, the video was uploaded. Then the embedded Youtube video was placed on the website, and it ended up working !
