“…There are diverse mixed methods models, which may be applied to the alternative assessment (Zhang, 2007b;Zhang, & Zhang, 2020). Creswell and Plano Clark (2018) introduced six mixed methods designs, which were applied to the research designs and data collections of the cognitively diagnostic assessment (Zhang, 2007a(Zhang, , 2007b: a) convergent parallel design, b) explanatory sequential design, c) exploratory sequential design, d) embedded design, e) transformative design, and f) multiphase design. Among these mixed methods designs, the exploratory sequential design is the best candidate to apply to the cognitively diagnostic assessment.…”
