1. Preview of Teaching Resources
Hello teachers! I am sharing a public lesson I taught in the 8th-grade information technology class – “Unveiling Electronic Tags”. This lesson revolves around the real project of “Smart School Uniform Manager”, integrating hardware operation, programming practice, AI assistance, and ethical reflection, making it a project-based learning example that combines technical depth with humanistic warmth.
2. Teaching Philosophy
Design Philosophy: Start from real problems to make technology learning meaningful.
This lesson introduces the common school issue of “uniform confusion” by playing a student interview video to resonate with the audience. Students transition from being troubled by the problem to using technology to solve it, naturally leading to the core technology of electronic tags. This design, which combines real situations with project-driven learning, makes technology learning no longer abstract but truly serves life.
3. Teaching Highlights
Highlight 1
✅ Highlight 1: Multimodal integration makes abstract principles “visual”.
Concepts like “electromagnetic induction” and “wireless communication” in RFID principles are very abstract for middle school students. I break through these difficulties in the following ways:
Physical Observation: Students use flashlights to illuminate ID cards and campus cards to perceive the existence of electronic tags;
Animation Breakdown: Use PPT to dynamically demonstrate the five steps of RFID operation: identity assignment → inquiry → energy response → reception and translation → decision execution; and decompose the complete story of swiping the ID card at the entrance into five steps.
Life Analogy: Compare the reader to a “teacher”, the electronic tag to a “student ID”, and the computer system to a “homeroom teacher” to help students understand the system collaboration mechanism.
This multimodal, multidimensional, and multi-representational teaching strategy truly realizes “making technology visible”.

✅ Highlight 2: AI Empowerment + Hardware-Software Integration, Making the Classroom “Broader”.
This lesson not only teaches technology but also teaches students how to learn technology:
AI-Assisted Exploration: Students act as “AI detectives”, using AI tools to search for application cases of RFID in logistics, healthcare, agriculture, etc., expanding their cognitive boundaries;
Hardware Practice: Students connect the RFID module to the main control board and write Python code to read tag numbers, experiencing the complete process from physical connection to data processing;
Project Closure: Establish a mapping between tag numbers and student names using a “dictionary” data structure, ultimately achieving the function of “swiping the uniform → displaying the name”, completing the project closure.
Highlight 3
✅ Highlight 3:Skill Enhancement: Ethical Reflection, Making Technology Education “Deep”.
Technology education should not stop at “how to use”, but also consider “why to use” and “how to use it wisely”. At the end of the class, I organized a mini-debate among students:
If we are tagged with electronic labels without our knowledge, do the benefits outweigh the drawbacks or vice versa?
Students discussed from the perspectives of “convenient management” and “invasion of privacy”, ultimately reaching a consensus: technology itself is neither good nor evil; the key lies in how it is used. This segment truly elevates teaching to the level of “information society responsibility” literacy.
“Unveiling Electronic Tags” is not only a technical lesson about RFID but also a literacy lesson on how to learn technology, how to think about technology, and how to use technology wisely. I look forward to exploring new possibilities in information technology education with more teachers.
