ABSTRACT: 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.
