This study aims to review the instruments of perceived usefulness (PU) among secondary school technology design (RBT) teachers utilizing the use of smartphones in teaching and facilitation (PdPc). A total of 125 RBTs teachers were involved as respondents in this study. The data were analyzed descriptively by access to Alpha Cronbach's reliability and EFA analysis using SPSS software. The results of the analysis show that the Alpha Cronbach value was 0.782 for perceived usefulness, which was greater than 0.60. Results from the EFA show perceived usefulness with Eigenvalues above 1.0. Perceived usefulness construct with a KMO value (Kaiser-Meyer-Olkin) 0734 > 0.5 showed that the items were adequate for inter-correlation and that Bartlett's test was significant (Chi-Square 441.43, p <0.05), anti-image value (Measure of Sampling Adequacy - MSA) for a correlation of more than 0.5 items with four items D7, D8, D9, D10 and D11 to be excluded because the value obtained is less than 0.50 and the total variance value explained is 63.54 percent. The overall findings indicate that items for perceived usefulness can measure and answer the objectives of the study.
