Network Administrator

  • Data Analyst: Cleans, processes, and interprets complex data sets to discover insights and guide operational decision-making.

  

Data Analyst

  • IT Support Specialist: Assists users with hardware and software issues, offers technical troubleshooting, and maintains helpdesk infrastructure.

  

IT Support Specialist

Learning Activities

  • Activity 1: Spot the Computing System

  

Spot the Computing System

  • Goal: Identify the five core components of a computing environment (hardware, software, data, people, procedures) within a real, everyday computing system.

  • Allocated Time: 12–15 minutes.

  • Group Structure: Small groups of 3–4 students.

  • Step-by-Step Procedure:

    1. Form small groups consisting of 3 to 4 students.

    2. Assign each group a familiar system to analyze: ATM, smartphone, self-checkout station, or online class portal.

    3. Small groups map out the exact hardware, software, data, people, and procedures that make up that assigned system.

    4. Each group delivers a 2-minute oral presentation summarizing their 5-component breakdown to the class.

    • Activity 2: CS or IT? Career Sort

  

CS or IT? Career Sort

  • Goal: Practice differentiating computer science roles from information technology roles and recognize areas of professional overlap.

  • Allocated Time: 10–12 minutes.

  • Group Structure: Student pairs transitioning to whole-class discussion.

  • Step-by-Step Procedure:

    1. Distribute or display job title/scenario cards (e.g., "writes a mobile app," "fixes a broken office network").

    2. Working in pairs, students categorize each card into Computer Science, Information Technology, or Both.

    3. Pairs share and justify at least two of their sorting decisions with the entire class.

    4. The class engages in discussion regarding cards that caused disagreement, examining why CS and IT fields frequently overlap in practice.
