Educational data mining - traditional vs. online learning

The six data sets were created for an undergraduate course at the Babes-Bolyai University, Faculty of Mathematics and Computer Science, held for second year students in the autumn semester. The course is taught both in Romanian and English with the same content and evaluation rules in both languages. The six data sets are the following:<br> - FirstCaseStudy_RO_traditional_2019-2020.txt - contains data about the grades from the 2019-2020 academic year (when traditional face-to-face teaching method was used) for the Romanian language<br> - FirstCaseStudy_RO_online_2020-2021.txt - contains data about the grades from the 2020-2021 academic year (when online teaching was used) for the Romanian language<br> - SecondCaseStudy_EN_traditional_2019-2020.txt - contains data about the grades from the 2019-2020 academic year (when traditional face-to-face teaching method was used) for the English language<br> - SecondCaseStudy_EN_online_2020-2021.txt - contains data about the grades from the 2020-2021 academic year (when online teaching was used) for the English language<br> - ThirdCaseStudy_Both_traditional_2019-2020.txt - the concatenation of the two data sets for the 2019-2020 academic year (so all instances from FirstCaseStudy_RO_traditional_2019-2020 and SecondCaseStudy_EN_traditional_2019-2020 together)<br> - ThirdCaseStudy_Both_online_2020-2021.txt - the concatenation of the two data sets for the 2020-2021 academic year (so all instances from FirstCaseStudy_RO_online_2020-2021 and SecondCaseStudy_EN_online_2020-2021 together)<br><br>Instances from the data sets for the 2019-2020 academic year contain 12 attributes (in this order):<br> - the grades received by the student for 7 laboratory assignments that were presented during the semester. For assignments that were not turned in a grade of 0 was given. Possible values are between 0 and 10<br> - the grades received by the student for 2 practical exams. If a student did not participate in a practical exam, de grade was 0. Possible values are between 0 and 10.<br> - the number of seminar activities that the student had. Possible values are between 0 and 7.<br> - the final grade the student received for the course. It is a value between 4 and 10.<br> - the category of the final grade: <br> - E for grades 10 or 9<br> - G for grades 8 or 7<br> - S for grades 6 or 5<br> - F for grade 4<br><br>Instances from the data sets for the 2020-2021 academic year contain 10 attributes (in this order):<br> - the grades received by the student for 7 laboratory assignments that were presented during the semester.

- SecondCaseStudy_EN_online_2020-2021.txt：包含2020-2021学年（采用在线授课模式）的英语课程成绩数据
- ThirdCaseStudy_Both_traditional_2019-2020.txt：为2019-2020学年两份数据集的合并集，即FirstCaseStudy_RO_traditional_2019-2020与SecondCaseStudy_EN_traditional_2019-2020的全部样本
- ThirdCaseStudy_Both_online_2020-2021.txt：为2020-2021学年两份数据集的合并集，即FirstCaseStudy_RO_online_2020-2021与SecondCaseStudy_EN_online_2020-2021的全部样本

2019-2020学年数据集的样本包含以下12个按顺序排列的属性：
1. 学生本学期完成7次实验作业所得的成绩，未提交的作业记为0分，成绩取值范围为0至10
2. 学生2次实践考试所得的成绩，未参加实践考试的学生记为0分，成绩取值范围为0至10
3. 学生参与研讨课活动的次数，取值范围为0至7
4. 学生该课程的最终成绩，取值范围为4至10
5. 最终成绩等级分类：
- E：对应最终成绩为9或10分
- G：对应最终成绩为7或8分
- S：对应最终成绩为5或6分
- F：对应最终成绩为4分

2020-2021学年数据集的样本包含以下10个按顺序排列的属性：
