Development and Validation of an Attitude Assessment Scale for the Use of 3D Printing in Education

The purpose of this study was to develop and validate a scale aiming to assess pre-service teachers’ attitudes towards 3D printing for teaching and learning processes. The data were collected from 250 pre-service teachers in different departments at a public state university. In order to test the validity of the scale, the exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were carried out. As a result of EFA, the scale included three factors; perceived ease of use, perceived usefulness, and intention to use, with 18 items in 5 point Likert type. The fit values from the CFA confirmed the three-factor structure of the scale. The correlations among the factors were positive, and collinearity among the factors was not calculated. The scale and the factors demonstrated a satisfactory level of internal reliability, ranging from 0.68 to 0.94. The findings of this study showed that the scale was valid and reliable, and could be used by researchers interested in technology integration in teaching and learning environments.
