Introduction (Original excerpt)

Welcome! Before we even write a line of code, you get to know someone: Linus Torvalds.

Didactic classification

Subjective objective

In the center of this module is the introduction to sequential processing of program instructions. It is made clear that programs are interpreted and executed as uniquely structured sequences of commands. Learners model a movement sequence through a linear arrangement of elementary control commands. The need for precise instructions is highlighted, as each individual instruction has immediate effects on the further course of the program. The connection between modeled action and its technical implementation becomes immediately tangible. This creates a basis for understanding algorithmic structures in later teaching phases.

Competence development

Understanding the sequential processing of program commands
Development of basic algorithmic thinking
Modeling simple action sequences through structured command sequences
Awareness of the importance of order in programs
Implementation of movement logic in elementary program structures
Analysis of cause-and-effect relationships within a program

Didactic added value in teaching

Structured progression when entering programming concepts
Clearly defined task assignment to focus on basic principles
Promoting systematic and step-by-step problem-solving
Transparent goal orientation through clear action goals
Differentiation possibilities through variation of command sequences

Course of the lesson unit

Move Linus

Create a sequence of elementary movement commands to direct a figure through an environment in a goal-oriented manner. The focus is on the correct order of individual instructions without using more complex control structures, thereby introducing and solidifying the principle of linear program execution.

Didactic Focus: Sequential Processing
Typical Challenge: Planning the Correct Sequence of Commands

Work Assignment (Excerpt)

Create a sequence of commands that leads Linus to the exit.
Use one instruction per step.
Pay attention to the correct order of the commands.

Hints for Classroom Practice

Short use as an introduction to algorithmic thinking possible
Differentiation through additional route variants or alternative solutions
Result verification by comparing different command sequences
Extension by introducing repetition structures subsequently possible
Connection to topics such as control structures or modeling of processes

This module connects fundamental algorithmic concepts with a clear, step-by-step implementation in the form of simple program flows.

The clear task structure supports transparent lesson organization and facilitates result verification; differentiation is possible through alternative solution paths.
