Procedures for Assessing the Quality of Electronic Learning Resources Using Petal Diagrams

Abstract

The concept of visualization of the results of expert evaluation of the quality of electronic learning resources is considered. Much attention is paid to petal diagrams and their use in the visualization process. The algorithm for calculating the area of the petal diagram and the influence of the order of parameters on the area of each petal are described. The criteria for assessing the quality of e-learning resources and their weights for each of the experts are presented. The roles of experts with weighting factors are shown. Complex indicators of quality of electronic educational resources for each expert are defined and the complex indicator for all experts is generalized. An algorithm for calculating the areas of sector petals, which can be used to calculate and evaluate the relative quality of ELR according to the relevant criteria is given. GeoGebra dynamic mathematics system was used to implement the method of determining a comprehensive assessment of the quality of ELR. The process of construction of the petal diagram in the system of dynamic mathematics GeoGebra with the given instructions is shown.
