Existing cognitive taxonomies classify learning objectives by mental operations but do not account for system impact, leaving a critical gap in commandline education where conceptually simple commands can have severe consequences. This work presents CogTax, a four-level cognitive taxonomy that integrates two dimensions: cognitive complexity, derived from Bloom’s Revised Taxonomy, and operational impact, which distinguishes observational, reversible, structural, and administrative operations. The four progressive levels range from safe read-only inspection to advanced system management requiring integration of multiple abstract models. Then, the taxonomy level is defined as the maximum of these dimensions, ensuring that both conceptual understanding and operational awareness are addressed. CogTax gives instructors a principled framework for sequencing course material and calibrating assessment difficulty, and gives students an explicit reference for self-assessment and gap identification. To demonstrate that taxonomy levels are automatically assignable, making the framework scalable without manual expert annotation, a classifier that combines syntactic representations derived from abstract syntax trees with semantic embeddings is trained. Evaluated on 585 expert-annotated Linux/bash commands, this combined approach achieves 89% accuracy, outperforming either representation alone, and demonstrates cross-language extensibility through structural equivalences across command languages.  \nKeywords: Cognitive Taxonomy, Constructivist Education, Bloom’s Taxonomy, Computing Education, Abstract Syntax Trees, Linux/bash, Cross-language Generalization, Command Classification, Embedding  \n∗ Corresponding author.  \nEmail addresses: [manuel.alonso.carracedo@uvigo.gal](manuel.alonso.carracedo@uvigo.gal) (Manuel Alonso-Carracedo), [ruben.fernandez.boullon@uvigo.gal](ruben.fernandez.boullon@uvigo.gal) (Ruben Fernandez-Boullon), [pedro.celard.perez@uvigo.gal](pedro.celard.perez@uvigo.gal)[ ](pedro.celard.perez@uvigo.gal)(Pedro Celard), [franjrm@uvigo.gal](franjrm@uvigo.gal) (Francisco J.

Introduction  \nTeaching command-line computing presents a distinctive pedagogical challenge: instructors must simultaneously balance the mental operations required to understand a command (cognitive complexity) and the potential consequences of executing it (operational risk) . In courses covering system administration, Linux/bash scripting, database query languages, or network configuration, students encounter commands ranging from safe read-only queries to operations that can irreversibly alter system state. Without a principled framework for organizing this complexity, instructors face three related difficulties. First, sequencing course material becomes ad-hoc, potentially introducing high-impact operations before foundational concepts are consolidated, imposing unnecessary cognitive load on learners (Sweller, 1994) . Second, designing examinations with calibrat","cbCais16jB22W4LH","https://ap.wps.com/l/cbCais16jB22W4LH","pdf",3073889,1,35,"English","en",105,"# Introduction\n## Core teaching challenge\n## Existing taxonomies and the identified gap\n## CogTax framework overview\n# Abstract (Taxonomy design and evaluation)","[{\"question\":\"What problem does CogTax address in command-line computing education?\",\"answer\":\"It addresses a gap in existing pedagogical frameworks by accounting for the real-world consequences of learner actions, not just mental operations.
