We elaborate on a new approach of assessing content-based epistemic clarity of college physics students in terms of their ability to discriminate between different epistemic warrants for propositions in a chained argument in physics. A threefold classification (nominal, physical, and mathematical) of warrants is used, with each class split into a…

A valid and reliable measurement tool has been developed to measure the teaching-learning process self-efficacy of instructors in higher education institutions. During the scale development stage, the scale form was e-mailed to 305 instructors, who were selected through purposive sampling method, working at the faculties of health, social,…

Validity of a measurement refers to appropriate test score meanings, uses, and interpretations (Messick, 1989; Kane, 1992). There are different approaches to validity: an evidentiary aspect of validity is one requiring gathering statistical evidence to evaluate test score meaning. A common approach to validation is comparisons of test score equity…
