DISTANCE LEARNING & COMPUTER BASED

1. VIa Interactive Television Classes 

2. Via the Internet

2 methods in Distance learning

Distance learning

Also called as distance education, e-learning, and online learning

Interactive TV classes

a form of education  in which the main elements include physical separation of teachers and learners during instruction and the use of various technologies to facilitate student-teacher and student-student communication

IVT Classroom

• teaching podium with a control panel for the cameras & monitors microphone for a teacher; computer hookup; document camera & fax machine

• in front of the room

• Back of the room

• Each student’s desk

Types of IVT classroom

In front of the room

• large TV monitor capable of showing several remote sites at one time orshowing the teacher to the remote sites 

• teacher wears a tracking device so the camera follows him or her around the front of the room

IVT classroom

Back of the room

• several monitors that enable the teacher to see students at the remote sites

IVT classroom

Each student desk

• Microphone & control pad that moves the camera toward the student when he/she activates the microphone

IVT classroom

To provide an effective alternative path to wider opportunities in education especially in higher education

Purposes and uses of ITV classes

earn at one’s own time frame

Advantages of ITV classes

Used even learners & educators are not able to meet in one place for learning

Disadvantages of ITVclasses

Via the internet

 “online or Web-based classes”

1. Synchronous classes

2. Asynchronous Classess

3. Development of Web based Course

Via the internet ; HOW

Synchronous Classes

Via the internet

• learning occurs when people interact in real time electronically via the internet or intranet

Asynchronous classes

Via the internet

• materials are located on a Web page that can be accessed at any time at the learner’s convenience

Development of Web based course

Via the internet

•  requires instructor content expert, Instructional designer or educational technologist

• Home-bound learning is achieved

• Consumes less time

Purposes of “VIA THE INTERNET”

• Mimics normal conversation

• Discussion in “real time”

• involve professional growths

• log on at any time

• adequate time to think through responses

Advantages of “VIA THE INTERNET”

• learners must be available at the same time

• Discussion progresses quickly and depth of ideas may suffer

• Slow typists may not participate as much

• Procrastination may not get involved in some of the discussion

• Postings may become very lengthy and time-consuming to read

Disadvantages of VIA THE INTERNET

1. Computer assisted Instruction ( CAI) 

2. The internet 

3. Virtual reality

Types of COMPUTER BASES teaching Stratehy

Computer assisted Instruction ( CAI)

instruction or remediation presented on a computer or computer systems

• Drills and practice

• Tutorials

• Computer fames

• Computer Simulations

• Multimedia presentations

Types of Computer assisted Instruction

Drill and practice

simplest level

• students have already learned certain information and are now presented with repetition & application of information

• teaching mathematical calculations

CAI

tutorials

• teaches a student a body of knowledge by presenting information &asking questions,giving hints if the student get stuck

• most useful in teaching material at the rule & concept level

CAI

Computer games

• _______________ can be good but they are not easy to devise

CAI

Computer Simulations

• _____________ may provide students with all the details about a particular patient situation & then ask them to assess the patient, arrive at diagnoses, plan interventions and evaluate care

• Students can take risks & make mistakes with no danger to the patient

CAI

Multimedia presentations

• hypermedia may incorporate text, sound tracks, graphics,still photos, animation,video clips, material from WWW

• programs can be saved on a laptop computer & shown to an audience with a computer projector Interactive VideoDisc (IVD)

CAI

To allow learners to progress at their own pace and work individually or problem -solve in a group

Purposes and Uses of CAI

the internet

a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols

• email

• New groups / discussion forum

• World wide web

The internet types

e-mail

• a method of exchanging digital messages from an author to one or more recipients

NewS groups/ discussion forum

• electronic version of corkboard;  a repository usually within the  Usenet  system, for messages posted from many users in different locations

WWW

• • A computer network consisting of a collection of internet sites that offer text and graphics and sound and animation resources through the hypertext transfer protocol (HTTP)

To provide global access to data and communications

Purposes/ uses of “ the internet”

1. Information

2. Accessibility

3. Communication

4. Entertainment

5.  job opportunities

6. online education

Advantages of “ the internet”

• Learners could be exposed to various forms of vulgarities such as violence and pornography. 

• It may be extremely addictive to learners

• Not every content posted on the internet is from reliable sources.

• Using devices for a prolonged period of time could contribute to various physical problems such as neck pain, back pain and eye pain.

Disadvatages of “the internet “

Virtual reality

computer-based, simulated three- dimensional environment in which the participant interacts with a virtual world

HOW:

 unique opportunity to practice complex & dangerous skills in a safe environment

Purposes / uses of Virtual reality

: learner does not just watc or read a simulation but participates in it as if this were a real world actually Experienced

Advantages of Virtual reality

• expensive

• people assume that they will automatically perform well in a real setting

Disadvantages of Virtual reality
