LESSON 9: Computer Teaching Strategies

• Why is computer use increasing greatly?

  1. hardware costs decrease
  2. software proliferates
  3. internet and WWW expand
  4. changes in HCDS
  5. make education cost-effective
• Learning with Computer Technology

  1. time-saving
  2. teach critical thinking and problem solving
  3. provide simulations of reality
  4. educate from a distance
  5. supports mastery learning
  6. minimize time on task
  7. provide instant feedback
  8. cognitive effects
• Advantages of Computer Instruction

  1. interactivity
  2. increased student motivation
  3. increased access to information
  4. instructional consistency
  5. reduction of teacher's repetitive tasks
  6. individualized instruction
  7. time efficiency
  8. cost effectiveness
• Greatest Advantages of Computer Instruction

  1. allows a person to interact in the learning situation
  2. can find information
  3. respond to questions
  4. manipulate variables
  5. solve problems
  6. create plan strategies
• Disadvantages

  1. many educators do not feel comfortable enough with CAI
  2. effect on personal and professional communication
  3. time investment needed to learn how to use the technology
• computer-assisted instruction - applications can be used in classrooms and lab, clinical units or homes
• drill and practice - simplest level of CAI; teaches mathematical calculations
• tutorials - second mode in which CAI must be written

  • most useful in teaching material at the rule and concept level
• computerized testing - used to evaluate student learning, for remediation purposes, or to assess student preparedness for licensing exam
• games - like board and card; not easy to devise
• simulations - student is functioning in a controlled environment

  • one of the most exciting and available
  • help to solve clinical problems and make sound decisions
  • may branch into tutorial mode
• multimedia presentations - sometimes called hypermedia

  • incorporate texts, sound tracks, graphics, still photos, animation, video clips, WWW materials
  • interactive videodisc - older form
• Criteria for Evaluating Software

  1. accuracy
  2. ease of use
  3. design
  4. appearance
  5. feedback
  6. cost effectiveness
• computer-managed instruction - used to manage, prepare, organize and evaluate educational experiences

  • programs designed to construct examinations
  • authoring systems (writing computer programs)
• internet - mammoth collection of computer continents, connecting many millions of computer

  • modem
• email - used to provide greater collaboration between teachers and students and students to students

  • listservs
• news group - similar to listservs

  • message appear in a general mailbox that everyone views
• world wide web - collection of millions of documents found on web pages that interface to internet
• WWW searches - has millions of sites affiliated with it

  • surf
  • search engines
  • URL
  • metasearch engines - aggregators
• 12 Best Search Engines

  1. Google
  2. Bing
  3. Yahoo
  4. Baidu
  5. AOL
  6. Ask.com
  7. Excite
  8. DuckDuckGo
  9. WolframAlpha
  10. Yandex
  11. Lycos
  12. ChaCha.com
• URL - uniform resource locator

  • http: protocol
  • www: world wide web
  • facebook.com: domain name
  • .com: top level domain (commercial site)
• Metasearch Engines

  1. Dogpile
  2. Ithaki
  3. Polymeta
  4. SearchSalad
  5. Seekz
• dogpile - when you want a compilation of results from all the major search engines
• ithaki - when you want your aggregated results to be ranked by an internal algorithm
• polymeta - when you want a superintelligent metasearch engine that can recognize colloquial language and uses an algorithm to organize results
• searchsalad - when you want a combination of search engine results and information from all the major review sites
• seekz - when you want a metasearch engine that produces the most relevant results and removes all duplicates
• Criteria for Evaluating WWW

  1. purpose
  2. currency
  3. credibility
  4. content accuracy
  5. design
• virtual reality - computer-based, simulated 3D environment in which the participant interacts with a virtual world
