Abstract

    The purposes of this study were to: 1) develop and test the efficiency of Auto-mechanic Precision Measurements Job Instructional Package Subject Code 20101-2009 2) test the effectiveness index of the developed instructional package 3) compare pretest and posttest learning achievement with the developed instructional package, and 4) study the satisfaction of the students toward an instructional package. This research implementation divided into 3 steps.1) Study of learning management problems of Auto-mechanic Precision Measurements Job Subject Code 20101-2009, for Certificate Level Curriculum, BE 2019 2) Create and develop the instructional package stage with practice teaching techniques. 3) Teaching Stage by using the developed instructional package. The sample consisted of 2 groups, the group of the instructional package development stage were 32 of 1^st year certificate students in Auto Mechanic group 1-2 at Mahasarakham Technical College for 2^nd semester of academic year 2020. And the group for Teaching Stage were 42 of 2^nd year certificate students in Auto Mechanic group 3-4 who enroll in Auto-mechanic Precision Measurements Job Subject Code (20101-2009) in 1^st semester of academic year 2021, using simple random sampling method. The research instruments to test the efficiency of the developed instructional package and test the effectiveness index of the developed instructional package were: 1) the developed instructional package, and 2) the satisfaction assessment students who used this instructional package. The used statistics in data analysis were percentage, mean, standard deviation and t-test dependent. Research findings were as follows: 1) the instructional package was appropriate at the highest level, and the instructional package have efficiency on a defined criteria; E1=82.89 and E2=80.92 the results for using the instructional package were found that: 2) the effectiveness index of the developed instructional package was 0.7730, the students had increased of knowledge 0.7730 or 77.30% 3) the achievement of students after using the developed instructional package was significantly higher than before at the .05 level, and 4) the satisfaction of the students found that the students have satisfied.    Additional research results from the use of developed instructional package for data analysis were found that: 1) the students who study with the developed instructional package, the learning behavior was high, 70.74% 2) the students who study with the developed instructional package, attitude and desirable characteristics were high, and 3) the experimental group who taught with this package was found that the developed instructional package is high quality.
