NEVER talk during a loud burst of background noise. Your class will not be able to hear you. NEVER use distracting mannerisms, such as tug- ging your ear or playing with a ruler or a pen. The  class  will  pay  more  attention  to  what  you are doing than to what you are saying. NEVER  “talk  down”  to  the  class.  It  will  cause animosity  toward  you,  and  you  will  lose  the attention and interest of the class. NEVER  lose  control  of  the  class.  They  will  be distracted and will not learn. Keep  your  presentation  interesting,  accurate,  and to the point. Toss in a comment on personal experience when  you  want  to  emphasize  a  certain  point,  or  ask questions if you are losing the interest of the class or of  an  individual.  The  object  is  to  keep  your  class working and receptive to the information you are pre- senting. Training  Topics A  wide  variety  of  topics  are  appropriate  to  a  combat systems/weapons  division.  In  addition  to  combat  sys- tems/weapons,  you  should  have  lesson  plans  and training  for  other  topics,  such  as  safety,  use  of  test equipment,  electronics  casualty  control,  general  military subjects,  and  basic  electronics. Chapter 1 discussed four standards that you can use as  a  basis  for  your  training  program:  (1)  naval  stan- dards,   (2)   occupational   standards,   (3)   personnel qualification standards, and (4) equipment standards. Use  the  applicable  naval   and   occupational standards to tailor your training program to cover the professional   and   technical   requirements   of   your personnel. Use the applicable  equipment  standards  when you  train  personnel  on  new  equipment  or  equipment with which they may not be familiar. Stress the impor- tance of equipment standards to personnel before they begin  maintenance  on  equipment  to  emphasize  the importance and quality of the equipment performance. Training  Publications The training chapter of Standard Organization and Regulations  of  the  U.S.  Navy,  OPNAVINST   3120.32, discusses the quarterly forecast, weekly schedules, and various personal and group training records that must be kept. The  Catalog  of  Nonresident  Training  Courses, NAVEDTRA 12061, lists training manuals and corres- pondence  courses.  The  Personnel  Qualification  Stan- dards   Catalog,   NAVEDTRA   43100-5,   contains   an alphabetical listing of PQS packages. Some  other  sources  of  information  are TYCOM  directives  and  work-center  directives; Manual of Navy EnlistedManpower and Person- nel Classification and Occupational Standards, NAVPERS   18068;   and Catalog of Navy Training Courses (CANTRAC), NAVEDTRA   10500. TRAINING  SCHEDULES  AND  RECORDS The scheduling of shipboard training requires the careful  attention  of  the  training  officer,  the  department heads,  and  the  division  officers  to  minimize  conflict with the activities of the ship and to ensure that the time allotted to training is used to the best advantage. The only  justification  for  a  record  of  training  is  that  it provides continuity to the training program by indicat- ing what training has been done. When  developing  a  training  schedule,  you  must consider the ship’s operating schedule and yard overhaul periods  assigned  by  the  TYCOM.  A  yard  overhaul  takes place approximately every 3 years.
