Abstract:
The purposes of this research were; 1) to development a project based blended learning in science and technology subject on design and technology for grade 10 students to meet
the E1/ E2 efficiency criteria, 2) to determine the effectiveness index of the developed project based blended learning in science and technology subject and, 3) to study the students satisfaction towards the learning. The population consisted of 40 students in grade 10 which was obtained by cluster random sampling using the classroom as a random unit. The research instruments were project based blended learning in science and technology subject on design and technology, learning achievement test, and a questionnaire on satisfaction. The statistics used for the data analysis were percentage, mean, and E1/ E2. The results were that;
1. The project based blended learning in science and technology in subject on design and technology for grade 10 students was developed with the efficiency at 81.25/ 84.34.
2. The effectiveness index was at 0.7253.
3. The students satisfaction towards the project based blended learning was found at a highest level (Mean = 5.52, SD = 0.56).
