Week Seven

Chapters Five & Six

Question 1: What is the Internet? What value does it hold for educators?

According to our text by Lever-Duffy & McDonald, the Internet is “a collection of interconnected individual networks” which has adopted a common communication format called TCP/IP and is not “owned or operated by any one entity.” The seeds of the Internet began to sprout when government agencies and research universities devised ways to share information with one another by networking their computers over long distances. With the advancement of computing power and telecommunication, the Internet grew organically as more organizations were linked to the existing networks. Internet service providers sprang up to provide Internet access to local schools and average citizens. Although relatively slow by today’s standards, data transmission via phone lines made the internet available in homes and school libraries across the nation. Now, the wealth of the internet is brought to us at much greater speeds by DSL service, cable modem, satellite, and even cellular technology. Just in the last 10 years, the Internet has paved the road for an information explosion which has changed the world as profoundly as did the invention of the printing press. Think about all the rapid communication tools used by many millions of people each day: email, internet forums, discussion boards, list-serves, instant messaging, online chat, remote desktop, file sharing, newsgroups, blogs, twitter, etc.

Before I studied chapter 7, I was unclear about the difference between the Internet and the World Wide Web (or just “the Web”). The term Internet refers to the complex interconnection of thousands of servers using the TCP/IP communications protocol to make digital information available to billions of individual users throughout the world. The Web refers to the digital content of the Internet arranged into accessible websites comprised of individual web pages residing on the servers which are the backbone of the Internet. Truly, the advent of the Internet is one of the most significant developments of modern civilization.

The Internet and the resources of the Web hold tremendous value for educators in three aspects: instant access to a vast knowledge base, global communication, and web-enhanced learning.

The Internet is the world’s largest knowledge base. Search engines, directories, and portals allow teachers to find resources for a variety of needs such as subject area content, professional enhancement, and classroom management. Examples of resources for subject area content include government and non-profit websites for public information, online encyclopedias, and public domain materials. Teachers can also take advantage of resources for professional development found on the Web. Professional organizations maintain websites or portals containing research articles and publications. ERIC is a free, online collection of articles relating to educational research and issues maintained by the U.S. Department of Education. Education stakeholders share best practices and various tools with one another via the Internet. Examples include grade book applications, lesson plans, templates, worksheet and quiz generators, and diagnostic surveys.

Educators should definitely tap into the Internet’s capacity to facilitate communication. For example, teachers can maintain current communication and promote parental cooperation by means of email and class websites. By posting homework assignments, schedules, weekly lessons, and even grades; parents and teachers can work together more effectively to make sure students are staying on track. Another example is students in a French language class corresponding via email and voice/video chat with students in a French-speaking country. These are opportunities that would have been unthinkable just 20 years ago.

Finally, creative educators can use the Web to enhance teaching and learning. As bandwidth and computer storage both have become less expensive, more and more rich multimedia and virtual reality learning experiences are available on the Internet. We see wonderful examples of web-enhanced learning in this IT645 course: podcasts, streaming video, e-book, blogs, web-based learning management system, and file-sharing (slideshows, syllabus, examples, etc.). In addition, the developing Web 2.0 phenomenon is making it possible for students to collaborate across schools, states, and even nations with text, video, and audio communication and group editing rights for project documents.

Today I finished the third part of the assignment on using productivity software. Even though I have used Word, Excel, and PowerPoint extensively for many different purposes, I wanted to push myself to use new features of the software whenever possible and make my designs as attractive as I could. I have always enjoyed using these applications, and I have learned all that I know by trial and error. For me this is a good way to learn because I enjoy the challenge of figuring out how to do things on my own. Of course, it is always important to know when to ask for help, especially in teamwork situations.

My scenario for these assignments is a 6th grade math class, and this is not too far from my actual experience teaching 7th grade math for one year.

I enjoyed working on the flyer because I was trying to incorporate the design principles I have been studying in my desktop publishing class IT 567. The most challenging part was creating the math-themed background to spice up the open area of the flyer. I used Microsoft Equation editor to make several formula objects which I resized, recolored, and rotated. The panther logo is a free proof from iStockphoto. I have purchased graphics from this source for previous projects. In order to post my flyer to this blog, I needed to save it as a PDF file. Microsoft has an add-in for Word 2007 which I downloaded from their website and installed. Then I uploaded the pdf file to Google Docs. Finally, I set the document to be shared with everyone and obtained Google's URL for the document. For best viewing, I suggest you click the download button on the Google Docs page so you may see the flyer in Adobe Acrobat Reader. The Google preview is low quality.

In this assignment I learned a great deal about graphs in Excel. Until now I had only rarely used the graphing capability of Excel, but I found Excel 2007 to be flexible and intuitive in creating graphs. Can anyone guess where I got the names for my "students"?

PowerPoint is one of my favorite applications. I love using animation, but I'm not a fan of sound effects. You will notice my limited use of sound only in places where I felt the animation was small and might otherwise not be noticed. This short quiz was not a problem for me since I had done something similar in IT 636. Again, I tried to use what I have learned about design including complementary color scheme and repetition of shapes.

I appreciate your feedback and suggestions. If you have any difficulty opening the project files please post a comment or email me at greenderry@gmail.com
Thanks for looking!

Question 3:
What are authoring systems? What is the difference between drill-and-practice software and tutorial software? When is it appropriate to use each in teaching and learning?

Rather than rely on off-the-shelf products, teachers often would like to create customized multimedia lessons that are tailored to their instructional plans and their student’s needs. This is why teachers should consider learning to use an authoring system. According to the Dictionary of Computing an authoring system is “a special application that allows you to create multimedia titles. Authoring software lets you design the pages of the multimedia book and place video clips, images, text and sound on a page.” Teachers can use authoring systems to make learning modules for use on classroom computers and for access from the World Wide Web. Authoring systems are designed to produce hypermedia format in which the user can control the path of the presentation by clicking on buttons or links on each page. Web authoring systems generate output in HTML code which is the standard for using on the internet. There are many authoring software systems to choose from ranging from inexpensive and simple to use all the way to advanced applications which can produce professional-looking websites and learning modules. Some authoring systems are even simple enough for students to use. Teachers may choose to produce a multimedia or web-based lesson to address a specific learning objective, to target a certain learning modality, or to provide differentiated instruction. These lessons can be used in large groups, small groups, or by individual students. Authoring systems can also be used to produce a class website or student portfolios. A commonly used authoring system is HyperStudio for Windows. PowerPoint includes hyperlink capabilities that transform it from a mere slideshow maker to an easy-to-use authoring tool.

The biggest difference between tutorials and drill-and-practice programs is in their use. Tutorials are used to present new material, whereas drill-and-practice programs are intended to reinforce material that has already been taught.

Compared to other forms of computer-based learning such as simulation and games, the presentation of material in tutorials is more structured and managed. However, tutorials don’t have to be strictly linear in their path; often they contain hyperlinks to allow the user some control over the experience. Good tutorials will incorporate effective use of instructional strategies as well as multimedia content. Advantages of tutorials include the student progress tracking and individualized pacing. A high-quality tutorial can be a valid choice for communicating new content to students. Tutorials also can be valuable for learning support, such as when a student needs more time on a topic or has been absent.

Drill-and-practice software is all about practice and feedback. Students use this type of software to apply skills and knowledge they have already learned and receive immediate feedback about their performance with the goal of improving the skills and reinforcing knowledge. Some educators worry that drill and practice programs will be boring for students and thus turn them away from the importance of the content. However, good use of multimedia components can go a long way to make drill and practice more interesting and engaging. Many drill-and-practice programs include automatic student progress tracking. High quality drill-and-practice applications may also include a diagnostic feature which designs a program of practice based on student needs. Drill-and-practice software is recommended for review, supplemental activities, and studying for formal evaluations.

Question 2: Why is it advantageous for educators to share resources and programs on a network? What concerns are associated with program sharing?

When schools invest in computer networks, they are gaining a productivity tool that is both powerful and cost-effective. The power of a computer network is that it allows users to share hardware, software, and data.

Networks allow many users to share hardware, thus saving costs. For example, a classroom equipped with a dozen computers only needs one networked printer which can be shared by all users in the classroom. All teachers in the school can easily share one centrally located color laser printer if it is networked. A teacher could simply send the job to the printer from her classroom computer and pick it up at the office when convenient. Networking allows maximum utilization of hardware resources.

When software is installed on a network server, it can be easily shared among a large number of workstation, which brings several advantages. Once installed on the server, new software is instantly available to specified workstations on the network. This saves the time-consuming process of going around to individual computers to install new software on each one. Maintaining and upgrading software is also simplified because the server can “push” upgrades out to workstation in a matter of minutes. Another advantage of network software is lower cost. Often vendors offer site licenses for software applications at a substantial savings over the total cost of an equivalent number of standalone packages.

One of the biggest advantages of networking for educators is data sharing. Teaching and learning generates a large amount of information (data). By storing much of this information in the server, it can be readily available to all parties who need access to it. For example, mathematics teachers may store a bank of worksheets, handouts, or masters on the server to be shared among themselves. Templates for lesson plans, attendance sheets, and other frequently used forms can be easily accessed on the server. By storing interdisciplinary project files on the server, students can access their project from workstations in any of their classes. Teachers have instant access to student records and basic information when that data resides on the server. A final example involves teacher collaboration. Recently there has been a push to integrate vocational education with academics by creating assignments which are evaluated by both a vocational teacher and the associated academic teacher. By storing the assignment in electronic form on the server, both teachers could easily access that assignment, grade it on their own criteria, and then release it to the student for viewing and/or printing from a workstation.

Without networks there could not be the phenomenon called “groupware”. Groupware is classification of software that allows connected groups of people to share information which makes the group more productive. Examples include group-accessible calendars, address books, and facility scheduling. A teacher, his students, and their parents could use groupware to share information such as a calendar of homework assignments or upcoming class activities. Other groupware applications allow teachers to monitor activity while students are working on computers anywhere in the school. New forms of communication have grown with the advent of network computers. Email, e-newsletters, and instant messaging are some examples of new tools for parent-teacher-student communication.

The major concerns associated with sharing of information and programs on a network revolve around issues of privacy and security. It is important that students do their own work and not access other students’ files for the purpose of stealing work. Also, teacher materials must be kept separate from student materials. These issues are addressed through the use of good network administration. User accounts are structured to give specific levels of access to students, teachers, and administrators. Each user is given a unique username and password. Network administrators must institute a good password management procedure so that passwords are changed periodically and are difficult to crack. Malicious users and hackers are a concern for network security, and the network administrator should have reliable firewalls and other measures for protecting against these threats.

While the sharing of information, data, software and hardware is the power of networks, it can also pose vulnerability. If so much of value resides on the server, what happens if it malfunctions or “goes down” as they say? Good network management calls for continuous backup and/or redundant systems so that data will not be lost and network down time will be minimized. Normally, teachers need not be involved in the technical aspects of server maintenance, but it is important for every teacher to have his or her own “Plan B” for those times when the server is down, the data has to be restored, or the hardware gets a glitch. From experience, I can say it’s a matter of when, not if. Always be prepared.
