How to dismantle a radio

Type of workshop: “How to dismantle a device”

Integrated methodologies: brainstorming, cooperative learning, Metacognitive problem solving,CLIL.

Students involved:6th class. Total number of students:16

Interaction of school subjects:ICT,Science,History.English.


  • Dismantle a radio and see how it works.
  • Make a video with English subtitles.


Learn about circuits and computers.

Learn about radio.

Learn about teamwork and problem solving.

Interact and collaborate by developing their views during the course.


First step: Brainstorming. Students entered the classroom and saw a radio. They were asked about any prior knowledge they might have about the radio or inventors .As a warm-Up activity students were shown images of radios from across history and asked them to attempt to put them in order. What did the first radios look like? What did they look like as they evolved?  In this way we could find out what they already know.

Second step: group work. The students, after they had been divided into small , mixted  ability groups, started their research. Collected information from the internet about  radios throughout history, how radios are used today, found out what “AM” and “FM” stand for and how those bands are different, what the frequencies on our radio dial represent, investigated the different inner parts of a radio. They researched why the size of radios has gotten smaller through advances of technology…from large radio tubes through transistors through microchips. Students also explored how advances in radio communications have impacted society. Finally they shared observations with their classmates.

Third step: From theory to practice.In the third phase,the students worked together,explored and discovered the operation and safe use of the tools that were about to use for the dismantle of the radio.Next, students (under the supervision of their teacher)dismantled a radio to find out how it works. We tried to have speculative discussions with the kids about what the various wires and other parts might do, including drawing connections between what we see on the outside of the machine and what we're seeing on the inside. The whole process was recorded by the students.

Tools: various kinds of screwdrivers, pliers and cutters.

Final step: make a video with English subtitles using media tools(windows movie maker, google search engine, youtube ,power point presentation)

Evaluation. Through this activity students had the chance to combine manual (using tools) and digital skills(make a video).They were given the opportunity to actively participate into something new. They did not only use their imagination, but also use computer research and library research skills. They also made predictions, analyzed, drew conclusions. It also helped them  expand their knowledge about the radio and where it came from.Finally,they developed their creative thinking  and critical ability through the solving of a problem.
