Justification for Interview v. Self-Report Instrument (Austin)

This particular instrument would be an interview instrument. An interview instrument would allow for less bias than a self-reporting instrument. A highly trained professional would administer the instrument to measure motivation and would record observations in the notated boxes. An interview instrument would allow for some structure; meaning that the responses are rigid and allow for little open-ended responses. However, interview instruments also allow some open-ended responses (Cohen & Swerdlik, 2018) that will allow for a deeper look into processes.

Number of People Participating

Characteristics of Respondents

Whom the Instrument would be Generalized (Austin)

The instrument would be used to measure motivation of students to learn within a public school in the United States. The instrument would be generalized to fit the general psychological development stage of growing children. The instrument would also be generalized to ensure that it does not appeal more favorably to urban versus rural populations. Furthermore, the instrument would not be culturally biased to influence responses based on ethnicity or race, as well as socioeconomic background. The instrument would be used to measure school aged children, ages 8-13, in terms of motivation to learn, taking into account the varying disorders that are present in public schools across the nation.
