基于粗糙集的程序设计实践课程形成性评价研究

The Formative Evaluation of Computer Programming Experimentation Course Based on Rough Set

形成性评价是一种新型评价方式,相对于传统的教学评价,形成性评价更能合理客观地评价程序设计实践课程的教学效果及学生的实践能力。构建了以教师、实验小组、学生本人、第三方专家为评价主体;以语法熟练程度、算法应用能力、算法设计能力、实验报告质量为评价指标的程序设计实践课程形成性评价体系。并对C++实验课开展了形成性评价研究,教学实践表明,对形成性评价学生满意度高达90%,实施形成性评后学生实践能力优秀率提高了18%。

At first the shortcomings of the evaluation methods of computer programming experimentation course is analyzed, the formative evaluation is a new evaluation method, compared with the traditional evaluation, it is more reasonable and objective. Teachers, students, the experiment group and the experts are the subject of the formative evaluation. The index of the formative evaluation includes 4 aspects： grammatical proficiency, algorithm application ability, algorithm design capability and quality of experiment report, the weight of the indexes is 16%, 30%, 30%, 24% in turn. The teaching practices show that the satisfaction degree to formative evaluation of student reaches 90 percent and the practical ability is improved by 18 percent after formative evaluation executed.
