Ultimately, this is not a technological problem but a cultural and pedagogical problem.

The problem with technological solutions is that they set up an "arms race" with the students, in which you will certainly lose. Electronics are constantly getting smaller and obtaining more means of communication, so a student who really wants to cheat will likely have a means that you won't be readily able to distinguish. Consider, for example, the recent emergence of smart watches: are you going to ban watches from the classroom? What about low-tech but still effective forms of cheating like scraps of paper? If you get a frequency scanner, will you be able to catch somebody using non-standard communication bands?

The best defense against cheating students is other students who understand that it cheats them out of the value of their well-earned grades. If you can inculcate a school culture where most students are not just not cheating but actively opposed to cheating, then it will be much harder for cheaters to prosper.

The second best defense against cheating is to design exams that are more about process than product. Think "show your work" and "essay question." Yes, it's possible that a cheating student will outsource their work and render themselves a puppet of an expert whispering guidance in their ear, but that's a lot harder to do than secretly googling for information about Kirchoff's laws. I am, in fact, a big fan of open-book tests, which tend to push students to focus on synthesis instead of memorization. This, I believe, has much more value to students in the long run, and also has the nice side effect of rendering high-tech cheating much less valuable as well.

It is a hopeless task trying to prevent cheating for standard exams.

The suggestion of jakebeal will not work. While I personally never cheated, I would never snitch on someone which cheats. You are working together as a group which builds social cohesion and teachers/professors are an outgroup. You simply do not do that. Apart from that it is not my business to prevent cheating.

The other thing is that the impression of "lazy" cheaters is often wrong. I often wondered why cheaters do often a staggering amount of work for cheating which they could have used for learning. They are getting all possible exams, write down the core questions, prepare their cheating sheets, build groups... There are people out there who are so good that you even do not see cheating in the exam from the next table behind although you know that they are cheating.

My electronics professor in the university solved the problem for himself: He allowed that students bring everything into the exam. Calculators, sheets, lexika, laptops. The students were divided in space, if necessary, he took two rooms.

So he designed the question in advance to be not solvable with pure knowledge approaches. He designed tasks, modified them so people who did read and learned the stuff understood what the design was doing (if they were not sure, they knew easily where exactly the necessary information can be found) and made the design so extensive that it takes time to read and solve the question sequentially. Only five questions for two hours.

The cheaters were stuck. Because the tasks were unique, they could not use old exams (If similar tasks were mentioned, you could bet that the professor modified them so that old approaches were useless or even traps). Information did not help, they had information, but not the knowledge to use it. Because the tasks were so extensive, the time penalty for smuggling out the questions, let them solve frantically by an expert outsider, smuggling them back and write them down was so prohibitive that it was not an option.

The spacing out was intended to make communication not impossible, but simply an ardous and easy to spot task. Even if someone who knew the stuff would help he simply was not able to tell the solution because it needed too much explanation.

Open book exams and speed

Some types of exams are rather immune to such cheating, namely exams designed to be taken with "open book" (i.e., any and all reference material allowed) with a rather strict time limit.

If questions are designed to test skills obtained during the course instead of memorization, then preparation of any extra "cheating" materials helps the learning process (as it's well known that transcribing material helps you also remember it better).

Another approach is that question time limits can be designed so that you can finish them all in time only if you know the answers right away - where you possibly could look up some answer (or ask it to someone else), but if you have to look up multiple answers would mean that you simply run out of time before even reaching half of the questions. I have had a bunch of subjects with such open book exams, and they were surprisingly effective at revealing differences between mastered/not mastered areas of study.

Ho risposto a una domanda simile tempo fa. Questa risposta potrebbe essere interpretata come un'estensione della precedente.

Lo stesso identico problema accade anche nella mia università e la mia opinione su questo argomento è solitamente accolta da commenti molto negativi.

Penso che la ragione della disonestà high tech non sia l'etica degli studenti. Riguarda il sistema di esame stesso. Mentre la tecnologia cresce in modo esponenziale quasi quadraticamente, gli studenti continuano a sostenere gli esami con carta e penna. Anche i compiti a casa sono progettati per consentire a uno studente di "leggere il libro del corso" mentre lui / lei può chiaramente usare Internet.

Quando uno studente utilizza alla lettera un articolo su Internet, si parla di plagio . Ma quando parafrasa, si chiama un buon compito .

Gli studenti dovrebbero essere in grado di utilizzare qualsiasi dispositivo desiderino. Telefoni cellulari, laptop, qualunque cosa vogliano. Le domande dovrebbero essere preparate di conseguenza. Gli studenti devono lottare per trovare la risposta corretta a una domanda.

Se una domanda è come "quanto è alto il Monte Everest", gli studenti imbrogliano. O uno potrebbe aver memorizzato la risposta e non esitare a aiutare un amico o semplicemente dare un'occhiata alla risposta digitandola nel suo cellulare.

Tuttavia, se la domanda è del tipo "per favore discuti i motivi per non scalare l'Everest", allora (i) non esiste un'unica risposta giusta, (ii) anche se i laptop possono essere usati gratuitamente durante l'esame, il lo studente dovrebbe fare una piccola ricerca per spiegare le ragioni e (iii) aiutare un amico diventa essere un idiota .

A proposito, ho non ho mai barato agli esami e non sto difendendo l'inganno Ma al momento un bambino è in grado di sbloccare e scegliere un gioco da giocare su uno smartphone, aspettarsi che adolescenti o adulti si tengano lontani dalla tecnologia non è molto ragionevole.

I metodi di esame devono stare al passo con la tecnologia solo come ogni altra cosa nella vita.

Cattive notizie: Google Glass viene utilizzato da sempre più persone e non possiamo farci nulla.

Some universities have taken to disabling the WiFi in classrooms to deal with the laptop use "problem". That doesn't get you around cellular data use on phones, and you can't legally jam cellular signals (in the US) as keshlam noted in their comment.

I am aware of several commercial products that can detect phones in areas they are not supposed to be used (typically used by the financial markets to spot inside trading). Such as those from AirPatrol, BV Systems and Libelium. Some of these you buy multiple sensors to work out which "zone" the mobile device is being used in.

Then I suppose to detect electronics generally (that are not connected to a network) you could go down the whole route of metal detecting. Unless they are using tiny mobile phones that are alleged to defeat metal detectors but as the devices are so small reading a vast sum of information off them discretely would be somewhat difficult.

Depends really how far you want to go (full airport style pat-downs?) and how much money you have.

La soluzione è molto più complessa di "Fai x per smettere di barare".

Stiamo entrando in una fase come società in cui la capacità di conservare una grande quantità di fatti non è importante quanto essere in grado di elaborare i fatti e trarne conclusioni. Con la ricchezza della conoscenza umana a portata di mano, cosa è più importante?

La capacità di ricordare un miliardo di fatti a volontà, o la capacità di elaborare un dato fatto in modo logico e intelligente insieme al capacità di scoprire fatti correlati?

Se non ottieni nulla da questa risposta prendi questa cosa:

Non vincerai mai questa battaglia. Gli imbroglioni saranno sempre un passo avanti.

The best way to counter cell phone use is to not allow cellphones.

In the "most strict" exams I have ever taken (the Canadian/U.S. Government recognized tests for knowing the English language), each person had their own bin in which they emptied their pockets into. No sweat shirts or hats allowed. A gentle pat-down was done, mostly just making sure pants pockets were empty, and one of those metal-detection or electronic detection wands briefly waved over me. All the exam preparation takes place in a different room from the room the exam was taken in, so you can't just leave stuff there before-hand.

During the exam, we were only allowed to use the tools given to us. There was very strict monitoring. Some portions were on a computer, but the short time limit on those sections meant that even if you could get around to the internet or whatever without getting caught, by the time you managed to look anything up the question would be over.

For my own school, there is an official "testing center" in which very similar procedures take place, though not quite as strict with the pat-down and metal detector - it is where all midterm and final exams are taken for every course. I suspect any student who puts enough thought into it and has the courage could cheat in this setting, but the consequence for being caught is very severe - an automatic failing of the entire class and possibly being expelled.

In the case where the exam is going to be taken in your every-day classroom, exam preparation for the previous strategy could be unfeasible, especially depending on the number of students. You'd need lockers, or bins, and some way to keep each person's stuff separate. And the time to sort all that stuff out. There's a couple other ways to enforce a "less strict" version of this policy:

• If the exam is going to be taken first thing in the morning, collect everyone's cell phone at the door before they enter the room. They can have it back when they are finished with the exam. (In some cases, you could collect all the phones in one bin - when everyone gets their phone back any missing piece of property should readily be apparent, but you'd have to keep everyone in the room until everyone is done and has their phone back. Even then, some issues could arise - there needs to be trust by all parties if they are going to share one "bucket" to put all their phones into - There probably isn't going to be that trust in a room of 25-40+ students.)

• Have each student place their cell phone on their desk/area in an easily visible spot. Keep extra attention on those who do not appear to have a cell phone, but be sure to still watch everyone.

Questa è una questione relativamente facile,

Dite loro di non usare telefoni cellulari, fategli firmare un pezzo di carta con scritto in caratteri grandi "NESSUN CELLULARE / DISPOSITIVO MOBILE, capisco che usando un cellulare / dispositivo mobile (inclusi ma non limitati a: ipad, iphone e / o altri tipi di dispositivi elettronici) FARLO FALLIRE AUTOMATICAMENTE IL TEST "firmato e datato. La minaccia e il seguito della punizione di ricevere effettivamente una F per l'esame, si diffonderanno a macchia d'olio in tutti i corridoi della scuola (il problema più grande con il completamento della punizione, molto probabilmente, sarà l'amministrazione scolastica, che ha bisogno di studenti di alto livello per motivi politici ...)

E / O

Hai un gruppo di volontari (potrebbero essere altri studenti di una classe diversa, genitori preoccupati, ecc. l'immaginazione è il limite ...) , che stanno dietro gli studenti e li osservano.

La combinazione di entrambe le tecniche garantisce un modo a bassa tecnologia di informare sulle conseguenze e rimuovere gli imbroglioni, combinandoli fa una forte presa di posizione.

Inoltre, se consentito, una stanza leggermente oscurata può dare a te stesso / ai volontari il vantaggio di individuare i classici schermi luminosi di un dispositivo mobile ...

Noterò che sono d'accordo con Amagii, almeno in parte , che cambiare i test da quello di pura memoria a quello di testare l'elaborazione del pensiero logico, può cambiare il modo in cui vengono effettuati i nostri test, riducendo il peso della "logica stupida", anche nota come ricompensa per avere una buona memoria, per ricompensare invece coloro che hanno la capacità di comprendere l'argomento (dopotutto anche gli accademici più grandi e qualificati tengono libri di riferimento, quindi perché costruire test su false premesse che non ne abbiamo bisogno?), che a lungo andare sarà molto più gratificante. Non solo per le attuali impostazioni accademiche, ma nel mondo reale.

Best of Luck.

Crea un'app per smartphone / tablet attraverso la quale viene somministrato l'esame stesso. Questo potrebbe essere semplicemente un browser ridotto al minimo, senza funzioni speciali come il supporto JavaScript, senza controlli di navigazione e che non persisterà se perde il focus, ad esempio, lo studente passa a un'altra app per imbrogliare. (Puoi consigliare agli studenti di abilitare la modalità aereo, quindi accendere il WiFi e connettersi alla tua speciale rete di test, che non fornisce l'accesso generale a Internet, per evitare il rischio di una telefonata inaspettata che ripristini il loro test.) per interrogare un server hardcoded sulla rete per l'indirizzo di una pagina di destinazione, da cui gli studenti possono selezionare il loro test, che viene fornito in un semplice formato HTML con controlli del modulo di base. Se l'esame è più lungo di un'ora circa, potresti anche fornire punti di ricarica.

Se uno studente non ha (o non desidera utilizzare) uno smartphone / tablet, può comunque fai il normale test cartaceo, ma in una piccola stanza separata, il che renderà banale individuare un dispositivo di contrabbando.
