Self-Discipline Practices Inventory in Learning Mathematics: Instrumentation Process
Self-discipline is necessary to keep everything in order and motivated while learning. This paper designs an instrument that measures student’s self-discipline practices in learning mathematics. The researcher used the measure approach introduced by Michael T Kalkbrenner last 2021. Measure is an acronym comprising: a) make the purpose and rationale clear, b) establish empirical framework, c) articulate theoretical blueprint, d) synthesize content and scale development, e) use expert reviewers, f) recruit participants, and g) evaluate validity and reliability. Self-discipline practice inventory, a ten item scale has been developed and validated. The results show that the newly created instrument possesses internal consistency reliability and construct validity.
