Answers for finals-educational technology

1. We always hear the word blackboard when all we see is green chalkboard in the classroom. Can you find out why?

Ans.

 Research done in the early sixties revealed that green was easier on the eyes of students, because there was lower contrast than on a blackboard.

2.  What is project based multimedia learning? What principles of teaching are very much illustrated by project based multimedia learning?

Ans.

 Project-based multimedia learning is a method of teaching in which students acquire new knowledge and skills in the course of designing, planning, and producing a multimedia product.

Project-based learning is an old and respected educational method. The use of multimedia is a dynamic new form of communication. The merging of project-based learning and multimedia represents a powerful teaching strategy that we call “project-based multimedia learning.”

3.What are the elements of project-based multimedia learning?

Ans.

The elements used in multimedia have all existed before. Multimedia simply combines these elements into a powerful new tool, especially in the hands of teachers and students. Interactive multimedia weaves five basic types of media into the learning environment: text, video, sound, graphics and animation. Since the mode of learning is interactive and not linear, a student or teacher can choose what to investigate next. For example, one does not start on the first page of a linear document and read to the end. Interactive multimedia learning mode is more like constructing a spider’s web, with one idea linked to another, allowing choices in the learner’s path.

4. Why use project-based multimedia learning?

Ans.

Project-based multimedia learning can add value to your teaching. In economics, value is added to a product when it is somehow made better or more useful to the consumer. Although we don't use the term much in everyday life, we are surrounded by examples. Our cereal has vitamins that are not part of the basic grains. The bottle of “one step” shampoo in the shower includes a conditioner.  You already have strategies for teaching your curriculum.

5. What are the disadvantages of the use of project-based learning and    multimedia project?

Ans.

Misuse or overuse of media:  Many multimedia programs are basically a technological remake of an existing technology.  Oftentimes this "remake" consists of "bells and whistles" simply for the sake of having "bells and whistles," rather than improving the learning potential.

Limited structural guidelines: Because multimedia is a relatively new field, it is difficult to measure or compare new multimedia programs to any standard, as none exists (Hasebrook, 1997).   As a result, distance education providers have limited structural guidelines upon which to base their operations.

Limitations of technology:  Multimedia that transmits across networks between the supporting organization and the personal computer takes up bandwidth.  A user with an older modem or a slower processor may not have access to the video, audio, or graphics required in a particular module. 

Limited support: When multimedia technology is implemented, technical support for learners and faculty is often non-existent.  This can result in the misuse of the technology.

Difficult adaptation:  Not all learning styles easily adjust to multimedia learning.  For example, Gregorc’s Abstract-Random (AR) learners are capable of adapting to other teaching methods, but the long-term "style flexing" can be stressful (Ross, 1997).

Cost:  The price of upgraded technology, as well as costs of hardware and software, can be substantial to the supporting organization when implementing and operating a multimedia instruction program.  Learners incur costs as well.  They must have access to advanced technology (e.g., upgrade their home computers or purchase a new computer in order to participate in the course).  The cost of training instructors in the new technology must also be considered

6. What are the steps involved in the use of project based multimedia learning strategy?

Ans.

* The teacher-coach sets the stage for students with real-life samples of the projects they will be doing.

* Students take on the role of project designers, possibly establishing a forum for display or competition.

* Students discuss and accumulate the background information needed for their designs.

* The teacher-coach and students negotiate the criteria for evaluating the projects.

* Students accumulate the materials necessary for the project.

* Students create their projects.

* Students prepare to present their projects.

* Students present their projects.

* Students reflect on the process and evaluate the projects based on the criteria established in Step 4
