a hybrid model for assessing student mathematical skills

Student assessment is a very important process in education, because it helps the instructor to determine student mistakes and to improve their performance by reforming his/her teaching plans. a hybrid assessment method using qualitative grades for evaluating student mathematical skills is presented in this work. the paper starts with the mathematical background which is necessary for the understanding of its contents. this includes basic information about fuzzy, neutrosophic and soft sets, and about grey numbers. it also includes a description of the use of the center of gravity (cog) defuzzification technique for assessing a student group’s quality performance. the cog technique is compared with the classical method of calculating the gp a index. the hybrid assessment method, which is based on all the previous concepts and processes, is developed next and the article closes with the final conclusion and some recommendations for future research.
