The Impact of Covid-19 On Higher Education in Poland – Study Based on Polytomous Item Response Analysis

The outbreak of the coronavirus has become a major disruption to colleges and universities all over the world, with most institutions canceling in-person classes and moving to online-only instruction. The pandemic also threatens to significantly alter nearly every aspect of college life, from admissions and enrollment to collegiate athletics. These concerns extend to the financial future of higher education institutions in a time of considerable financial instability, both in the form of unexpected costs and potential reductions in revenue.

In this paper we present results of own research in sudent`s satisfaction from on-line learning in Poland. We use polytomous item response analysis for item analysis. We compare graded response and generalized partial credit model, we also present item characteristic curve and item response category curve as an interesting and powerful tool for visualization. All calculations are carried out in R.
