The Creating and Efficiency of Teaching Materials on Basic Machine Tools. Subject Code 20100-1007, Base on the Vocational Certificate Curriculum in 2019, Office of Vocational Education Commission.

Abstract

     The  purposes  of  this  research  were  1)  to creating  a  Teaching  Materials  on  Basic  Machine Tools,  Subject  Code  20100 - 1007. Base  on  the Vocational  Certificate  Curriculum in 2019, Office of  Vocational  Education  Commission. 2)  to  find the efficiency of Teaching Materials to the standard criterion of 80/80 3)  to  compare  the students’ learning  achievement  before  and  after  learning  with  the  Teaching  Materials  and 4) to study the students’ satisfaction  to  the  Teaching   Materials  on  Basic  Machine  Tools, Subject  Code  20100 - 1007. The  sample   random purposive sampling in this study were 52 students, 37  students   from  the  1^st  year certificate  students  group  1  and  group  5  in Machine  Shop  field  and  15  students  from  the 1^st year certificate students group 5 in Auto Mechanic  field  at  Nong  Khai  Technical  College in first semester 2020 Academic year. The research instruments ware 1) the Teaching Materials  on  Basic  Machine  Tools,  Subject   Code 20100-1007  2)  the  learning  achievement  test 3) students’  satisfactory  evaluate  questionnaires. Statistical  analyses  used  in  this  research  were  descriptive  statistics  and t - test  dependent. To  study  the  learning sample  group  was  taken  to  perform  Pretest, then  the  theory  was  instructed  by  using  the Teaching Materials and the exercises were conducted  after  each  lesson  completion.  The Posttest  was  used  at  the  end  of  course.  the score form the exercises and tests were calculated  to  evaluate  the  efficiency.  Finally, the  students’  are  satisfaction  to  the  Teaching Materials  The  result  of  this  research  found  that : 1)  Teaching  Materials  on  Basic  Machine  Tools, Subject  Code  20100 - 1007  was  at  80.69/80.63 in  the  efficiency,  that  determine  of  selected efficient  standard  criterion of  80/80.   2)  The learning  achievement  of  students  in experimental  group,  after  practiced  with  the lessons  ware  significantly  at  the  .05  level  and  3)  The  students’  satisfaction  on  the  teaching  materials  was  at  high  level
