7-14. In which of the following steps in the teaching  process  should  the  instructor spend the most time and effort in correcting  students’  errors? 1. Warmup 2.  Presentation 3.  Application 4.  Testing 7-15. Learning Objective: Identify the various  types  of  audiovisual  (AV) aids  normally  used  in  the  CRP activities;  determine  the  value and uses of AV materials. Aids  that  are  used  by  instructors  to  help communicate  their  ideas  to  their  students would  be  identified  as  what  type(s)  of aids? 1. Teaching 2. Instructional 3.  Audiovisual 4. Each of the above In  answering  questions  7-16  through  7-18,  select from  column  B  the  type  of  nonprojected  aid  that would  be  the  most  appropriate  for  the  purpose or use given in column A. A. Purposes/Uses       B. Type of Aids 7-16. Used to show the     1. Graphs organization  of a firm 2. Illustrations 7-17. Used to show 3. Brochures increases  and decreases  over 4. Charts time 7-18. Used  for  review purposes Learning Objective: Recognize the various  types  of  projected  aids used  by  CRP  personnel  and  determine the proper use of each type. 7-19. Which of the following AV tools would NOT  be  classified  as  projected  aids? 1. Overhead   transparencies 2. Filmstrips 3. Slides 4. Graphs 7-20. 7-21. 7-22. 7-23. 7-24. 7-25. What  is  the  main  disadvantage  to  the  use of  filmstrips  in  CRP  teaching  and  presen- tations? 1. They  cannot  be  repaired  without  losing some  of  the  information 2. They are too expensive 3. They are too difficult to operate and  maintain 4. They cannot be easily repaired 16mm  motion  pictures  are  not  widely  used in  CRP  presentations  because  of  which  of the  following  characteristics? 1. They are-too expensive 2. They are too general in the nature of films 3. The material may become obsolete due to  policy  changes 4. Each of the above ALL EXCEPT which of the following properties  of  8mm  films  make  it advantageous  to  use  that  type  of  film? 1. They are less expensive to produce 2. The equipment is less expensive 3. The equipment is easier to operate 4. It is easier to present a single concept  with  them One  of  the  advantages  to  video  cassettes is that they can be erased and reused after  the  material  has  served  its  purpose, making  them  less  expensive  than  other types. 1. True 2. False Learning Objective: Determine the importance  of  audiovisual  aids  in training  and  presentations;  determine the  correct  procedures  for  the  care and  maintenance  of  AV  materials. One of the major advantages to the use of  audiovisual  aids  in  CRP  training  is that  practically  all  of  the  training  can be  accomplished  by  the  audiovisual  aids themselves  making  it  possible  to  use fewer  instructors. 1. True 2. False If  an  audiovisual  (AV)  presentation  is being  prepared  for  distinguished  people, at least how many dry runs should be made before  the  actual  presentation? 1. One 2. Two 3. Three 4. Four 45
