The Statistical Analysis and Evaluation of Examination Results of Materials Research Methods Course

The statistical analysis and evaluation of examination results provide the theoretical basis for teaching quality and management. Materials research methods course is the key course for the undergraduates major in materials science and engineering. Based on the examination results of inorganic nonmetal materials engineering specialty students in the first term of 2011-2012 school year of Wuhan University of Science and Technology, the quantitative analysis for several parameters including difficulty, discrimination and reliability were investigated. The results indicate that the distribution of examination scores approximate to normal distribution. Difficulty of the exam paper belongs to median level, and discrimination of this is qualified as well as reliability. Thus it was concluded that the design of the examination paper was good and dependable.
