dETECT (Evaluating TEaching CompuTing) is a model for the evaluation of the quality of instructional units for teaching computing in middle school based on the students’ perception collected through a measurement instrument.
The objective of the dETECT model is to analyze instructional units in order to evaluate the quality in terms of quality of the IUs, computing experience and the perception of learning, from the learners’ perspective in the context of teaching computing in middle school.
The measurement is operationalized by the development of a questionnaire to be answered by the students at the end of the instructional unit, in order to obtain their perception about the quality of the instructional unit.
The dETECT model was systematically developed and evaluated based on data collected from 16 case studies in 13 different middle school institutions with responses from 477 students. Our results indicate that the dETECT model is acceptable in terms of reliability (Cronbach’s alpha α=.787) and construct validity, demonstrating an acceptable degree of correlation found between almost all items of the dETECT measurement instrument. These results allow researchers and instructors to rely on the dETECT model in order to evaluate instructional units and, thus, contribute to their improvement and to direct an effective and efficient adoption of teaching computing in middle school.
