2. Perspectives that define educational technology

   • Educational technology is viewed as both processes and tools
     • It is important to begin examining four different historical perspectives
       • Perspective #1: Educational technology as comunications media
         • In this perspective, instructors proposed that media delivered information in concrete and effective ways
           • The view of educational technology as delivered media has dominated areas of education
       • Perspective #2: educational technology as instructional systems and insrtuctional design
         • Due to World War II military and industrial trainers needed personnel quickly so they advocated using media to develop effective materials, procedures, etc. with technology
           • This perspective has evolved into human performance technology to improve human productivity and competence
       • Perspective #3: Educational technology as vocational training
         • They believed that an important function of school learning is to prepare students for their work and vocational training can be a practical means of teaching content
           • This view brought a shift in vocational training getting K-12 schools away from industrial arts curricula centered in woodworking printing shops
       • Perspective #4: Educational technology as computer systems
         • As computers began to transform, teachers began to see that computers also had the potential to aid instruction, this perspective encompassed both instructional and administrative support applications
           • Educational computing became educational tecnology

3. How the past has shaped the present

   • Era 1: the pre-microcomputer era
     • teachers began using computer systems only since microcomputers came into common use, but before this universities were using systems to develop computer assisted instrucrion via long distance connections
   • Era 2: The microcomputer Era
     • Integrate circuits made computers smaller and portable so teachers began to bring them into the classrooms, they were called microcomputers
       • Districts began to purchase networked integrated learning systems , three other technology initiatives were, the computer literacy movement, videodisc-based curriculum and the logo movement
   • Era 3: The internet Era
     • Internet open the doors to the first browser softer designed to allow users to use hyperlinks, with this interest for technology sprang to life again.
       • Websites became a primary form of communication for educators, this use of internet created virtual schools wew students and teachers are separated by time interacting via computers
   • Era 4: Mobile Technologies, social media, and open access Era
     • In early 2000's when portable devices made internet access, some constant connectedness transformed educational practice, the ease of access to online resources drove several moments
       • Distance learning
       • Electronic books
       • Mobile access
       • Open acces

4. Today's educational technology resources: systems and applications

   • Technology Facilities: Hardware and configurations for teaching
     • Microcomputers
       • Sometimes reffered to as desktops or laptops, remain a mainstay of classroom computing
     • Handheld technologies
       • even smaller devices that mke easier to teachers and students to view communicate and share information
     • Display technologies
       • Devices that support whole-class demonstrations or information from a computer
     • Imaging technologies
       • these devices allow the development and ise of images ranging from still photos to full-motion videos
     • External storage
       • Sometimes a device is needed to hold large files that won't fit easily on storage media or made a backup copy
     • Laboratories of networked computers
       • These are easier to maintain and secure; networking software can monitor individual performance in groups
     • Computer arrangements in classrooms
       • These are more convenient and accessible to both teachers and students, but teachers may stretch available units when there are not enough for each student to have one
     • Peripherals
       • Input devices, such as keyboards that make microcomputers more functional

5. Conditions that shape practice

   • Social issues
     • Privacy issues
       • GPS technologies can pinpoint the exact location of someone, so it is dangerous to expose personal information without user's knowledge
     • Health-related concerns
       • problems such as hearing loss from headphones, or time spent at videogames can affect physical health of people
     • Malaware, viruses, spam, and hacking
       • Malaware are malicious software can damage, destroy, distrupt operations or spy on the operation of computers
   • Educational Issues
     • Lack of technology funding
       • Recent economic downturns have meant decreased education funding, this downturn comes at a time when technology expenses are on the rise
     • Reliance on online learning
       • Increasing numbers of virtual courses are being offered, and virtual schools are becoming mainstream part of U.S. education, but not all students have skills needed to use them
