Validation of the Teacher Decision-Making Inventory: Measuring Data-Based and Intuitive Dimensions in Teachers' Decision Process
Fri, April 22, 8:00 to 9:30am PDT (8:00 to 9:30am PDT), Manchester Grand Hyatt, Floor: 2nd Level, Harbor Tower, Harbor Ballroom DAbstract
It is assumed that teachers use both intuition and data in decision-making. To our knowledge, no valid scales are available to measure both dimensions during the teachers’ decision process (problem definition, data collection, sense making, evaluation of alternatives). Building on the integrated framework we constructed in earlier research, the main aim of this study was to develop and validate a Teacher Decision-Making Inventory (TDMI). 101 teachers in adult education participated voluntarily in a web-based survey. Based on the good EFA factor loadings, the CFA fit indices and the internal consistency (Cronbach’s alpha), we conclude that the TDMI is a valid psychometric tool that can be used to assess the intuitive and data-driven dimensions of teachers’ decisions in large-scale quantitative research.
