d. Instructional Media Selection
Among  many  types  of  media  which  are  available,  teachers  should carefully choose the most appropriate one based on some considerations. Strauss
and  Frost  1999  in  Seth  2009:  26  propose  nine  key  factors  which  should  be considered in selecting media. They are:
a  institutional resource constraints b  course content appropriateness
c  learner characteristics d  professional attitudes and skill levels
e  course learning objectives f  learning relationship
g  learning location h  time synchronous vs. asynchronous
i  media richness level Furthermore, Reiser and Dick 1996 in Seth 2009 state three criteria in
selecting the good instructional media. They are: 1 Practicality
The practicality includes the availability of the media, cost efficiency, and time efficiency.
2 Students appropriateness It  is  about  to  see  whether  the  intended  media  are  appropriate  for  the
developmental and experimental levels of the students or not.
3 Instructional appropriateness It includes three main points, which are:
a  the appropriateness of media for the planned instructional strategy; b  the efficiency and effectiveness manner offered by the media;
c  whether  the  media  will  facilitate  the  students  acquisition  of  specific learning objective or not.
6. Interactive Multimedia
a. The Definition
Richards  and  Schmidt  2002:  345  explain  multimedia  as  the  use  of several  different  types of media for a single purpose, e.g.  as in  a video that uses
film, audio, sound effects, and graphic images. They also add that multimedia is a collection of computer controlled or computer mediated technologies that enables
people  to  access  and  use  data  in  a  variety  of  forms:  text,  sound,  and  still  and moving  images.  Vaughan  2008:  1  says  that  multimedia  becomes  interactive
when the users of multimedia application can control what and when some parts of  the  application  contents  will  be  delivered.  Added  to  this,  lesson  on  CAI
Computer-Assisted  Instruction  materials  may  involve  a  question  on  the computer,  a  response  from  students,  the  feedback  from  computer  telling  the
students  if  the  answer  is  “correct”.  In  CAI,  such  activities  are  said  to  be “interactive” Richards and Schmidt, 2002: 265
