Description

CogTax classifies bash commands covered in a course by two integrated dimensions: "cognitive complexity (C)" and "operational impact (O)". Levels run from information query/observation (L1, read-only commands such as ls and cat) through basic modifications (L2), structural understanding (L3, pipelines and permissions), to advanced system management (L4). Integration follows L = max(C,O), so a command's level is set by whichever dimension is higher, ensuring instructors and students must address both conceptual mastery and operational awareness.

Design Implications

Context

Requirements

  • Each examination question must be tagged with its taxonomy level so agreement can be analysed as a function of question complexity

Constraints

  • The article notes the formula requires only at least level-L understanding or at least level-L effects, not necessarily both

Target Learners

  • second-year undergraduate Computer Engineering students in an Operating Systems course

Learning Goals

  • Linux/bash command-line proficiency across information retrieval, file manipulation, structural operations, and advanced system management
