In this study, a collocation method based on the truncated orthonormal Bernstein polynomial was adopted to obtain an approximate solution for the generalized pantograph equations with proportional delay under some initial conditions. The adopted method is based on transforming both of the generalized pantograph equations and the adopted conditions into matrix equation which corresponds to a system of linear algebraic equation. The reliability and efficiency of the proposed scheme are demonstrated by some numerical experiments and then validated by Math lab 15 package

This study aimed to use the factor analysis, which is a scientific method for analyzing multivariate data and reducing it to a smaller number of factors.. The researcher depend on data obtained through a questionnaire whose paragraphs were inspired by a student’s opinions of the College of Administration and Economics / University of Basra for the academic year 2019 -2020, with whom they were contacted electronically to find out the reasons for students' reluctance to electronic education and accept it as an alternative to classical education in light of the pandemic conditions of Corona.The researcher relied on the questionnaire of (22) questions as variables for the study.Results were obtained using the statistical program spss v.19The study concluded that the variables were reduced to (8) basic factors, which explained a variation of (72,221%) of the total variance.And the most important factors are that e-learning leads to introvertedness and that it is an innovation that must end and the interruption of the Internet and the electrical current and the lack of knowledge in the use of electronic platforms and the lack of students' possession of smart phone devices and their own computers that make the process of e-learning difficultand tiring
