In a longitudinal study, researchers were able to examine the significance of the COVID-19 pandemic on the professional well-being of math teachers. On a scale of 1 to 4, the mean emotional exhaustion of teachers increased from 1.89 in 2019 to 2.41 in 2021. At the same time, enthusiasm for teaching decreased on average, from 3.52 in 2019 to 3.21 in 2021.
