| # Dataset Overview |
|
|
| This dataset captures detailed interaction logs from 781 students in the Department of Computer Science at VNU-HCM University of Technology (Vietnam) over the 2023 and 2024 academic years. It covers two courses: |
|
|
| - **Programming Fundamentals (PF)** – first-year course; prerequisite: Introduction to Computing |
| - **Data Structures & Algorithms (DSA)** – second-year course; prerequisite: PF |
|
|
| Both courses run for six weeks, each week concluding with an exam on the previous week’s material. |
|
|
| ## Student Section Grouping |
|
|
| Students are divided into three groups: |
|
|
| - **L (Regular):** 572 students across 15 classes, standard admission scores |
| - **CC (Credit-Constrained):** 184 students across 3 classes, lower entrance scores with higher tuition |
| - **DT (Deferred/Repeat):** 25 students retaking the course or improving prior grades |
|
|
| ## Weekly Topics & Assignments |
|
|
| 1. **Week 1:** |
| - Object-oriented programming (OOP) |
| - Recursion |
| - ArrayList |
| - Singly linked lists |
| 2. **Weeks 2–5:** |
| - Doubly linked lists |
| - Stacks & queues |
| - Sorting algorithms |
| - Binary trees & AVL trees |
| - Search algorithms |
| 3. **Week 6:** |
| - Hash functions |
| - Graph theory |
|
|
| Each week’s assignment has multiple programming questions (396 total), each with 1–10 unit tests (3,312 total). |
|
|
| ## Logging & Actions |
|
|
| In our interactive coding environment, we record: |
|
|
| - `start_attempt` |
| - `precheck` (public test cases; gives immediate feedback) |
| - `save` |
| - `check` (private test cases; more stringent, may incur penalties) |
| - `finish_attempt` |
|
|
| On private checks, students see only a numerical score. |
