The effect of Blended Learning on Achievement of Career and Technology 4 for Grade 11 students

Abstract

Blended instruction in Career and Technology 4 is a combination between a conventional instruction focusing on classroom participation and a media technology assisted instruction by integrating advantages of both approaches in designing a blended instruction with higher efficiency. The objectives of the study were 1) to develop and examine efficiency of an e-learning instruction on Career and Technology 4 subject and 2) to compare learning achievement between Grade 11 students who learned with blended instruction and the conventional approach. The samples in this study were Grade 11 students in 3 classrooms (40 students each) from a total of 7 classrooms who enrolled Career and Technology 4 subject at Sriboonyanon School in the academic year 2014, selected by using cluster random sampling method. The 3 samples were used for courseware efficiency examination, blended instruction, and conventional instruction, respectively. The research instruments included a blended e-learning instruction on Career and Technology 4, an instruction evaluation form and a 20-item learning achievement test with the Item Objective Congruence Index (IOC) = 1.00, difficulty Index = 0.38-0.80, discrimination = 0.25-0.65 and reliability = 0.89. The data were analyzed by using t-test.

The results showed that efficiency E₁/E₂ of the instruction was at 92.92/94.38, and learning achievement in Career and Technology 4 of the students learning with the blended instruction was significantly higher than the students learning with the conventional instruction at 0.05.
