Radio-frequency identification in schools

Radio-frequency identification in schools is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Radio-frequency identification in schools rather than just read about it. In short: Various schools have been using radio-frequency identification technology to record and monitor students. United States It is thought that the first school in the US to introduce RFID technology was Spring Independent School District near Houston, Texas.

Key takeaways

Radio-frequency identification in schools belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Radio-frequency identification in schools to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Radio-frequency identification in schools from memory before moving on to harder problems.

Reference excerpt

Various schools have been using radio-frequency identification technology to record and monitor students.

United States It is thought that the first school in the US to introduce RFID technology was Spring Independent School District near Houston, Texas. In 2004, it gave 28,000 students RFID badges to record when students got on and off school buses. This was expanded in 2008 to include location tracking on school campuses. Parents protested in January 2005 when Brittan Elementary School issued RFID to the students. Administrators at a school in Sutter, California, were offered money to test RFID from InCom and issued RFID-chipped ID tags to students. Students and parents felt they were not fully informed about the RFID and questioned the tactics the school used to implement the program, and the ethics of the monetary deal the school made with the company to test and promote its product. Parents quickly squashed the program with help from the American Civil Liberties Union. In 2012, Northside Independent School District, San Antonio, Texas introduced active RFID, worn on a lanyard around the student's necks. One student refused to participate in the program and was expelled from school, after a court case. The school eventually dropped the RFID program and started tracking students with cameras instead.

UK In 2007, Hungerhill High School, Doncaster, UK, tried RFID chips sewn into students' blazers. Ten children tested the RFID for attendance. There were privacy concerns, and the trial was stopped. West Cheshire College integrated active ultra wideband (UWB) RFID into their new college campuses in Chester in 2010, and Ellesmere Port in 2011, to tag students and assets using a real time location system (RTLS). Students wore the active RFID tags around their necks. West Cheshire College stopped RFID tagging students in February 2013. A series of Freedom of Information requests were sent to the college about the RFID tracking of students. Specifications of the active RFID at West Cheshire College:

Ultra wideband RFID tags emit brief radio frequency signals across the entire 6.35 to 6.75 GHz frequency band. Average battery lifespan of a RFID tag is seven years. Receivers, which can receive tag signals up to 328 feet away, are located throughout the campus buildings, in order to ensure that the tags can be pinpointed regardless of where within the school a student might be. RFID tags provides accuracy to within 1 meter (3.3 feet). RFID Tag transmission rate of once per second. West Cheshire College uses RFID with a real time location system. The real time location system enables observation of student and staff in peer groups.

Germany After a school shooting in Germany in 2009, which claimed 16 lives, the Friedrich-von-Canitz School implemented a real-time location technology over Wi-Fi. The solution was developed by the German company How To Organize (H2O) GmbH in cooperation with teachers and the local police force.

India A.B.Patil School, Sangli, Maharastra implemented UHF technology to keep track of student in school premises.

Passive RFID Passive RFID is used routinely in schools to register teachers and students and to provide access to services such as photocopying and door access.

Worked examples

Example 1 — a first encounter with Radio-frequency identification in schools

Start with the simplest possible case. Write down what Radio-frequency identification in schools claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Radio-frequency identification in schools before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Radio-frequency identification in schools ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Radio-frequency identification in schools

In research: Radio-frequency identification in schools appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Radio-frequency identification in schools in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Radio-frequency identification in schools is common in secondary-school and first-year university syllabi. It links to neighbouring topics Child safety, Radio-frequency identification, School and classroom behaviour, so understanding it makes those chapters shorter.
In everyday life: Look for Radio-frequency identification in schools outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
