In this study, a mobile learning adoption scale (MLAS) was developed on the basis of Rogers ' (2003) Diffusion of Innovations Theory. The scale that was developed consists of four sections. These sections are as follows: Stages in the innovation-decision process, Types of m-learning decision, Innovativeness level and attributes of m-learning. There is one question at the level of classification regarding the investigated characteristics of the participants in the first three sections of the scale. The last section of the scale is composed of 18 items and 5 sub-dimensions in the 7-item Likert type. MLAS was developed in three stages. In the first stage, a detailed review of literature was performed and an item pool was formed. In the second stage, explanatory factor analysis was performed to determine the factor structure of the scale while confirmatory factor analysis was performed to test whether the factors formed confirmed the theory or not. In the final stage of the study, the reliability of the scale was determined through item, test-retest reliability and internal consistency (Cronbach Alpha) analyses. In conclusion, the scale developed within the scope of this study was shown to yield valid and reliable scores.
