Abstract
ObjectiveTo describe the validation and reliability assessment of a rubric designed to assess the participants’ teaching portfolios and identify teaching excellence among teaching and learning curriculum (TLC) program participants. MethodsFollowing focus groups with program leadership at a single TLC program, an initial rubric was developed, consisting of criteria mapped to 5 domains, to be rated on a 4-point scale. The rubric was then redistributed to the TLC program leadership and external stakeholders for evaluation of face and content validity. The rubric was piloted using teaching portfolios from 3 cycles of the program. Cronbach αwas used to measure internal consistency and a 2-way random-effects model was used to assess the inter-rater reliability. ResultsA total of 18 portfolios were independently evaluated by 4 raters. The overall mean Cronbach α for internal consistency was 0.90 and ranged from 0.65 to 0.84 by domain. The overall mean intraclass correlation coefficient for inter-rater reliability was 0.95 and ranged from 0.57 to 0.91 by domain. ConclusionThe rubric evaluates characteristics of teaching portfolios important to internal and external stakeholders and had good to excellent internal consistency and inter-rater reliability. It can be adapted and applied by TLC programs to identify teaching excellence.
