Concepts of Validity: Bridging Concepts and PracticesUBC-Paragon Webinar Series 2021-3

Much of what travels under the umbrella of validity theory and validation practices is 
the methodology of measurement (testing, assessment, and surveys).

How should one go about doing and evaluating measurement validity? 
How should one go about doing and evaluating measurement, testing, and assessment?

Nonparticipation (Unit Nonresponse) in Surveys Webinar

Woitschach, P., & Zumbo, B.D. (2021, March). Nonparticipation (Unit Nonresponse) In Surveys: A Practitioner’s Guide to the Conceptualization, Impact of, and Adjustment for Unit Nonresponse [webinar]. Vancouver, B.C.: British Columbia Patient-Centred Measurement.     To view the videos and access the supplementary materials please click the tab on this website or click [SURVEY NONRESPONSE]

Nonparticipation (Unit Nonresponse) In Surveys: A Practitioner’s Guide to the 
Conceptualization, Impact of, and Adjustment for Unit Nonresponse -- 3-Part Webinar 

A three-part webinar that aims to take data analysts and applied researchers with 
little background in statistical survey science through the conceptualization,impact 
of, and statistical methods for the adjustment for nonparticipation (unit nonresponse) 
of statistical surveys. Either see the tab [SURVEY NONRESPONSE] 

The webinar reports on simulations of the impact of unit  nonresponse as well as a 
description and demonstration of adjusting for unit nonresponse using propensity score 
weighting- including example data, R code using Twang, and SPSS syntax using the 
Complex Survey module.

Embedding IRT in Structural Equation Models – UBC-Paragon Webinar Series 2021-1

Common research questions in assessment and validation studies that use regression are:
–   Which of the variables is most predictive of the criterion measure?
–   What variable(s) is most explanatory of our test scores?

Assembled Validity- Connections to Validity, Language Testing, and Student Evaluation of Teaching

Zumbo, B.D. (2020, November). On “Assembled Validity”: Connections to Validity, Language Testing & Student Evaluations of Teaching. Invited address hosted by the University of East Anglia, School of Education and Lifelong Learning, Norwich, UK. [Online Virtual Address].  To view the video, please click here.

Drawing on Kane's argument-based approach to validity and Toulmin's later work on 
cosmopolitanism and diversity, this work asks whose validity arguments and evidence 
are being presented. 
Remarks about and broader implications of Addey, Maddox, and Zumbo's 'Assembled 
Validity': With connections to Validity Theory and Validation, Language Testing, 
and to University/College Uses of Student Evaluations of Teaching. (November 30, 2020).
