eric.ed.gov har udgivet: The aim of this research was to examine university students’ anxiety about mathematics, teaching mathematics in the 21st century and the views on mathematics teachers. A total of 100 students studying in 10 different departments of the Faculty of Economics and Administrative Sciences of a private university in the 2018-2019 academic years participated in this study. The data were collected by demographic questions, semi-structured open-ended questions consisting as well as questions about mathematics teaching in the 21st century prepared by the researchers and through the ‘Mathematics Anxiety Scale’. According to the results, there were significant differences in terms of the mathematics anxiety level of students who graduated from high school those have low average maths grades. Meanwhile, an average level of anxiety was observed data collected from… Continue Reading →

Item response theory (IRT) models are applied to these tests to estimate the ability of students (as latent variable in the model). In order for quality IRT parameters to be estimated, especially ability parameters, it is important that the appropriate number of dimensions is identified. Through a case study, based on a statistics exam for students in higher education, we show how dimensions and other model parameters… Continue Reading →
