Validating survey instruments

30-Jun-2020 05:52

The instrument, basically a three way slider, was validated using a simple preference study based on a comparison to an identical survey using a radio button selector.

In the study, pre-service teachers indicated classroom management, technology skills, use of concrete models in teaching, course management, assessing student understanding and meeting state standards as issues of prime importance.For the questions and tasks together, the sensitivity estimates were 100% for parkinsonism (n = 21), 96% for peripheral neuropathies (n = 22), 96% for stroke (n = 22), and 96% for epilepsy (n = 22), while the specificity estimate was 86% (n = 21).Analogous estimates were computed for the set of questions, for the set of tasks, and for each question and task individually.The literature is void of the assessment of pre-service preferences toward various aspects of their teaching mission with respect to the tripod of pedagogy, content knowledge and course management, and other triples of applicable teaching elements.

In this work, a solution to measure a teacher's views toward such a triple is offered by way of a three-way slider embedded in an equilateral triangle.

In the colors example this may be reflected by the subject preferring red to blue, blue to green, and then green to red.
