Data on use of a computer-marked on-line assessment in engineering education over the course of five years

This fileset presents the data obtained though implementing an on-line computer-marked assessment in a second-year core civil engineering course in an Australian university. The data is gathered on-line in five years from the first year of implementing this quiz in 2011 to 2015. Students were allowed to attempt the quiz multiple times over a certain period of time, longer than a week. A large question bank was constructed with several variants for each question. Students faced randomly selected variants of questions in each attempt. At the end of assessment period, the best score of each student was recorded as their mark for the quiz. An anonymous on-line survey was conducted every year after the end of the assessment period in which students were asked to answer a number of questions and provide their opinion about the quiz.<br> The data presented here includes students’ marks in each attempt, the time they spent on each attempt, and anonymous survey results.<br>

本数据集文件集收录了澳大利亚某大学二年级核心土木工程课程中，在线计算机评分测评所采集的数据。该数据的在线采集周期为五年，自2011年该测验首次实施起至2015年。学生可在为期一周以上的特定时段内多次参与该测验；项目组构建了涵盖每道题多种变体的大型题库，学生每次参与测验时，系统将随机为其分配对应题目的变体。测评时段结束后，每名学生的最高得分将被记为该测验的最终成绩。每年测评时段结束后，项目组都会开展匿名在线调查，邀请学生回答若干问题并分享对该测验的看法。
本数据集涵盖学生每次参与测验的得分、单次测验耗时以及匿名调查结果。
