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