Equipment need for online classes

A functionning computer

A good internet connexion

A visioconference software

A microphone

A earphone or earbud

A webcam
A table lamp / light

You are registered on an online tutoring platform. You are more motivated to take the plunge than you have never been before. And you just found THE ideal teacher for you!

However, in order to be entirely ready to begin et so your classes are as efficient as they can be, you need the right equipment.

Here is everything you need to learn at best from home.

A functioning computer

It can seem obvious and you may already have one, but a functioning computer or a tablet a must.

Whether it is a desktop or a laptop, any computer will do and will allow you to take your classes in good conditions.

Nevertheless, prefer one with Windows rather than iOS. Indeed, you will have a larger choice of the software to download for the videoconference.

If your computer has Windows, getting an advanced version is recommended. Classgap only works with devices from Windows 7 and Mac OS Yosemite onwards. These browsers’ updates are mandatory!

A good Internet connexion

The next thing you absolutely need is a good Internet connexion. A video conversation that cuts off all the time, where you can only hear every second word is not really ideal to follow distance courses. It is a waste of time, it can impair patience and you will not be efficient. It obviously does not help to stay motivated to learn.

Therefore, an internet connexion via optical fibre is the best. Thus, you will, have a smooth conversation with your teacher, making the exchanges easier and so the learning process. For this reason, it is necessary to have a minimum data rate of 5MB.

In order to know if you Internet connexion is enough, you can do a test online to check your debit speed or directly call you supplier.

However, it is possible that your connexion is to low and that you do not have access to Internet. Therefore, You can get an Ethernet cable if you are to far from the bow. Otherwise, here are other available options, such as coffee shops, coworking spaces, individual rooms in libraries etc… Where you can easily have access to Internet without connexion issues.

A videoconference software

Some online tutoring platforms have their own videoconference system on their website. For example, Classgap has a virtual classroom at its users’ disposal. It contains all the necessary gear to take lessons on the Internet: video, chat, text editor, excel sheet, digital board, share screen option, different views… Anything you might need for a quality class.

Thus, there is no software to have, everything is provided already.

Nevertheless,sometimes, downloading a videoconference software is mandatory. There are many alternatives. You can opt for a free one, such as Skype, Google Hangouts, Talky etc… These ones will enable you to have a very basic and easy to use chat and videoconference. 

However, they might not be the most adapted software to follow classes, you may soon be limited. But, it is also possible to download a chargeable one or to create an account on a chargeable platform. For example, GoToMeeting or Webex are more advanced alternatives than the free ones mentioned before. They present more features and options.

A microphone

Being able to communicate smoothly with your teacher is more than important when taking classes online. Indeed, a course does not only go in one way, it is a dialogue between the teacher and the student, the later must be able to express himself, ask questions etc…

Therefore, a microphone functioning properly is mandatory. If the one on your laptop does not work, use a headset. It is quite affordable and ideal. You can easily find one from 20€, which is enough.

A webcam 

Finally, is being able to hear the teacher is necessary, seeing him is not mandatory but is highly recommended. It allows a better grip between the student and the teacher and to develop a real human relationship. In addition, they can understand each other better, show things physically and not only digitally etc… For these reasons, it is important to see your teacher.

Therefore, the webcam is one of the necessary equipment for an online course. Most of the recent computers already have one within the device. But if yours does not work or if you computer does not have one, then you can get a webcam, individually, to add on your device, for 15€ on the Internet. It is a small investment which will improve the quality of your learning.

To conclude, before starting your distance lessons, make sure you check that the camera and the microphone are properly configured as predetermined. It is possible to do it from the Google Chrome parameters. Sometimes it is the reason why it may not work.

Only These Two Things…

You actually just need two things.

1.    An online screen recording software tool. I use screencast-o-matic, and with it, you can record everything you do on your computer. So you can record yourself doing a power point presentation on your computer while narrating it, and that would be the video. Or you could record yourself going through a software tool and explaining how to use it. Or you could go through a website and show people how to use that. So for example, let's say that you're teaching Photoshop, you could open up Photoshop and show them exactly step by step what to do, how layers work, how all this stuff works. And then there you have a video that you can use in your online course.

2.    The other thing you might need is a good microphone, and you can get a good microphone for about $40 to $60 or a higher-end mic for $100 to $200. But really all you really need is a decent quality microphone ,or even a microphone headset like some of the video gamers use that has good quality sound. And like I said, you can get that for about $60. The screencast tool that allows screen recording is about $18, so all told for about $70 you're in business.

Most important components of a virtual classroom are:

·         Visual: You may increase the visuals by using a good webcam and not relying on the integrated webcam which comes with your laptop. anything similar to

·         Audio: The entire session is a disaster if either one of you can’t hear each other properly. My advice would be to use a noise-cancelling headfone or earphone (preferably the former) for easy and smooth flow of communication

·         Pen Tablet: In order to use the whiteboard provided to you for writing purposes you could use a pen and touch tablet. It’ll give you good control over the board so you could write effortlessly and teach complex things.

Thanks for asking. You need a desktop/laptop/iPad to access the virtual classroom. If you want to use the video then a webcam too. Many desktops/ laptops have webcam embedded like I have in mine. Then I seldom use the video as it requires very high bandwidth. If you are teaching Science or maths which involves a lot of writing on the board then you need a pen tablet ( i use Wacom Bamboo). It is connected to the computer.

That depends on what type of teaching you will be doing and where.

For most colleges and universities require only a computer and Internet access. Some do expect that you will do live sessions (like webinars), and a headset or microphone is a great option and better than built-in microphones.

If you are creating your own courses for Udemy or another site, then you might want a camera. The microphone is still the important investment. You can record voice over PowerPoint as an easy way to create a video. Personally, I think the world is moving towards more informal video and a phone/tablet or webcam should be sufficient for most audiences.

To be an online tutor, here are the technical requirements:-

1.    Stable Broadband Internet connection, Preferably 512kbps and above

2.    Headphone with Microphone

3.    Pen-Tablet used for writing easily on the board

The 6 Best Microphones For Online Teaching

While most headsets that are designed for chat or online teaching come with a built in microphone, what if you want to use a pair of headphones that do not have a microphone?

Your built-in internal microphone on your laptop should be acceptable in most instances, but just like getting a decent webcam allows you to upgrade your video – getting a dedicated microphone will do the same for your audio which is just as important if not more important.

So what should you look for in buying an external microphone for online teaching? Here is what we here at Teach and GO suggest:

Low price

Microphones that are designed for voice recording are actually quite affordable. With the more premium options being over $100, you can find a decent microphone for a fair price and we’ve tested out quite a few different options.

There is no need to spend an excessive amount on something as simple as a USB microphone for a laptop unless you tend to do more advanced things like voice over work or YouTube videos.

Plug and play usability

Microphones can come with various advanced options to pair with a DSLR camera or be something as simple as a USB connection with a laptop. As we are only looking at quality microphones for voice recording, more expensive and complicated options are not included on this list.

We want something simple that just works out of the box. You plug it into your laptop or computer, your device recognizes it and all you have to do is select it as the audio option when in your online class.

Small, portable size

Some external microphones designed for laptops and professional voice recording are big. The popular Blue Yetti microphone comes to mind. While it does produce high quality audio, it’s way to big to use for an online class. Only small, portable and easy to use microphones made our list.

Another reason is that we also don’t want the microphone to appear in the video, so small is the way to go.

The Best Microphones for Online Teaching

So with that short buying guide out of the way, here are the best, most affordable and practical microphones that are ideal for online teaching. These microphones are the right mix of small size, low price with high quality audio:

·         Blue Snowball

·         Fifine Mini Goose Neck

·         CMTeck USB Computer Microphone

·         Fifine USB Microphone

·         Samson Meteor Mic

·         Jounvio Desktop USB Microphone

·         Zoom H2N

Blue Snowball – Best price and performance microphone

Small, good price.

The Blue Snowball is the little brother of the more premium Blue Yetti. It rose to prominence as a microphone of choice for aspiring pod-casters due to it’s surprisingly good audio quality.

For strictly voice work (not singing or recording instruments) the Blue Snowball opens up a wide variety of options for the online teacher. You can now improve the audio for your online class, online courses all for a low price. The only issue with the Blue Snowball is the build quality of the wire that connects it to your laptop.

Pros:

·         Low price, excellent audio.

·         Small and portable.

·         Easy to position as needed.

Cons:

·         Build quality could be better.

Fifine Mini Gooseneck microphone – The tiny option for laptops

Very small, ideal for an online teacher.

This little gooseneck microphone is very small and ideal for anyone who teaches English online using a laptop (which is most of us). It’s small, no frills microphone that plugs into your laptop via a USB connection and gives you much improved audio over your internal audio.

This is the budget microphone to get if all you’re looking to do is get something that will improve the audio of your online class. It has no advanced features as you should expect but it does allow you to use a headset of your choice and still have quality audio without pickup too much background noise.

Pros:

·         Small. Seriously, this thing is perfectly paired with any laptop for improved audio.

·         Good build quality and it’s portable.

·         Much improved audio quality over your laptops built in audio.

Cons:

·         Not for professional voice recording or YouTube videos.

CMTeck USB Computer Microphone – The Noise cancelling option for Desktops

Made for desktop.

This is a good (not great) USB noise cancelling microphone. Perfect for any laptop or desktop. With it’s low price, long cable and small size, this is an excellent option for any type of video call.

While this particular model is designed for online gaming, it doubles quite well for the online teacher. With it’s small body and long goose neck design, this microphone is easy to setup and position out of sight of your webcam while conducting class.

Pros:

·         Noise cancelling audio recording.

·         Goose neck design so you can position the microphone as needed.

Cons:

·         Small, but not as small as other options on the list.

·         As it’s a cheap microphone, the audio recording is good for video calls but not much else.

·         Designed more for a desktop than a laptop

Fifine USB Microphone – The low priced premium option

A solid mid range that is a step up from the Blue Snowball.

This is a high quality USB condenser microphone that is designed for online content creators that won’t break the bank so to speak. While it’s made for individuals who want to get into streaming, voice over work or YouTube videos it’s actually quite a nice microphone for the online teacher.

As a condenser microphone, it will produce better quality audio than a cheaper desktop microphone like the CMTeck. It will also do a fine job of isolating your voice and cancelling out background noise.

Pros:

·         This microphone is designed for prosumers and online content creators in need of quality microphone.

·         USB plug and play design makes this microphone an easy to use option.

Cons:

·         Bigger than the Blue Snowball but it has a more professional design.

Samson Meteor Mic – The Blue Snowball Competitor

Another affordable, little microphone.

This is a well designed, premium looking little microphone that pairs well with any laptop for better audio. It’s the main alternative to the more popular Blue Snowball.

It comes with a built in tripod that is also removable and it connects to your device via a USB like all the other microphones. This particular model does not have any pro features like a mic gain control or ability to change the direction of the sound pick up.

But if you’re looking for a more premium microphone compared to the Blue Snowball. One that has better build quality, then consider the Meteor Mic from Samson.

Pros:

·         Good voice quality recording.

·         Nice build quality.

·         Small portable size.

Cons:

·         This is still a mid range phone microphone and lacks various pro features.

Jounvio Desktop USB Microphone – The cheap option

Cheap, expendable microphone.

Making the bottom of the list, this is the best cheap microphone you can get. It’s designed for a desktop but you can use it with any device that allows for a USB connection.

A no frills, adjustable neck microphone designed primarily for a desktop setup that does not have an internal mic. This microphone provides a very mediocre upgrade if you already have an internal microphone on your laptop.

If you teach with a laptop I would skip on this microphone. But if you’re a teacher who uses a desktop and you need a microphone for online class this is a great cheap option.

Pros:

·         Excellent price

·         Small size with a long cord

Cons:

·         Mediocre audio, on par with the built in audio of a laptop.

Zoom H2N – The most flexible microphone you can get

For online content creators.

The Zoom H2N is an impressive little microphone. It’s the best microphone on this list but also the most expensive. It combines all the pros of all the other microphones with none of the cons (the main con being it’s price).

This is a very small microphone that you can plug into your laptop or desktop via USB for some high quality audio. It also has a mic gain control as well as the ability to record audio from any direction as it has numerous microphone built into it.

That means you can turn off one side or turn on all sides. Last, you can use it with a DSLR camera or as a stand alone recording device due to it’s battery powered nature. However, when plugged in via USB it does not use battery power. The accessory kit is sold separately.

Pros:

·         Small, high quality microphone.

·         Advanced pro features for recording in multiple situations.

·         Perfect device for teaching, online courses, YouTube videos or a microphone for your camera.

Cons:

·         Price, this is quite expensive and excessive if all you’re looking to do is have better audio for online class.

·         The accessory kit that comes with a mini tripod, wind filter and blue tooth remote is not included.

Best Microphones for Online Teaching

So that is it for Teach and GO’s best microphones for online teachers. If you already have a headset that has a built in microphone I would skip on getting an external microphone.

If however you wind a pair of headsets you really like but they don’t have a microphone then consider getting a cheap external microphone. Our favorites on the list for teachers are the Blue Snowball as you can use it for more than online teaching and the amazingly small Fifine gooseneck microphone.

The 7 Best Webcams For Online Teaching

Laptops today have integrated HD web cams of varying quality (most are at 720p). When you’re starting out as an online teacher, it’s fine to rely on your built in webcam but over time if you start teaching a lot of classes you may want to consider upgrading your camera as it’s your most important tool.

Your company may ask you to upgrade your camera as well if you become a popular teacher. Lastly, you may just want to upgrade because you’re a dedicated teacher who want’s to provide an excellent classroom experience.

If you’re looking for a way to step up your video quality for cheap then you may want to consider getting a small, inexpensive, dedicated webcam. Webcams perform much better than a built in webcam in regards to low light performance, depth of field, video quality, colors and on screen space. You can also move an position a webcam with ease.

This is not only helpful for teaching online classes, it is also helpful if you ever want to create YouTube videos, do live streaming or hold a conference call.

So what should you look for in a webcam for teaching English online? We suggest the following:

1080P webcam

Most integrated webcams in laptops record at 720P. 720P is fine for most online teaching companies. But if you’re buying an external webcam, why not get an webcam that is a significant improvement over what your laptop has?

Integrated microphone

Some webcams are strictly webcams, but the ones that are actually worth buying come with a built in microphone. While your laptop has a microphone built into it as well, the audio from an external webcam with a microphone will be much better and is worth purchasing.

The 7 Best Webcams for Online Teachers

So here is Teach and GO’s guide to the best webcams for online teaching and sort of working professional looking to upgrade their camera for a good price.

·         Logitech C922 Camera

·         Logitech C270

·         Razer Kiyo Streaming Webcam

·         Microsoft Lifecam HD-3000

·         Logitech BRIO

·         Vitade Webcam

·         Jelly Comb 1080P webcam

Logitech C922 – The Best Price and Performance

Get it today on Amazon.

This is the webcam we suggest getting here at Teach and GO. It has excellent audio and records at 1080P. Your field of view will be much wider, colors more vibrant, video more crispy and clearer, improved low light performance for those early mornings and it sound better.

This camera is a massive improvement over any integrated webcam and allows you to do all sorts of other fun things you previously could not do. Want to create YouTube videos? You can now. Need a camera to create a video introduction? This can do that too.

Pros:

·         This web camera has much improved video clarity, low light performance, sound, colors and field of view over the previous C920.

·         Designed for working professionals. This webcam was made for online teachers.

Cons:

·         The only con is the price. It’s not too expensive but it is going to cost more that a “cheap webcam.”

Logitech C270 – The Budget Option

Marginally better than an integrated webcam.

This camera is your cheap webcam option. It is better than your integrated webcam because is has a wide angle field of view and it has better low light performance than a web camera. It came out a few years ago and is known to have a few compatibility issues with Windows 10.

If you’re set on getting a good cheap webcam this is it, but it’s not without it drawbacks.

Pros:

·         Cheap

·         Better low light performance than your built in web cam

Cons:

·         It’s known to not work well on Windows 10 as it’s an older webcam

·         The video tends to be a bit cropped in when recording.

Razer Kiyo Streaming Webcam – LED Light Built In

Bright white light.

This camera is the main alternative and competitor to the Logitech C922. The Logitech has a more natural color profile but the Razer Kiyo has a built in LED light which is quite helpful for online teaching. We prefer the Logitech as most teachers have some sort of video lighting.

If you’re looking for a webcam that can record in 1080P and has a built in LED light this camera is an excellent choice.

Pros:

·         1080P recording

·         Built in LED light to brighten your face

Cons:

·         A bit expensive, but the quality is there

·         Colors are not as vibrant as the C920

Microsoft Lifecam HD 3000 – The Better Budget Option

Mediocre but still better than most built in webcams.

Microsoft makes various, quality accessories that are quite affordable and the Lifecam HD 3000 is no different. If you’re looking for a wide angle webcam that works with Windows without issues then consider getting the Lifecam.

It’s an improvement over your built in webcam due to the wide angle and better low light performance. This webcam however only records up to 720P.

Pros:

·         Wide angle

·         Works with Windows 10 as it’s from Microsoft

Cons:

·         720P recording. It’s acceptable for online teaching however but not for YouTube videos or live streaming.

Logitech Brio – 4k Webcam

Best webcam money can buy.

This is a 4k webcam. 4k is a video size that is the next step up from 1080P. This webcam has auto-focus, facial recognition, can record at 4k at 30 frames a second or 1080p at 30-60 frames a second, dual mics built in for good audio, has a wide angle lens built in and 5x digital zoom.

This is an expensive, feature rich webcam designed for professional content creators. It makes the list because this is the best webcam on the market currently.

Pros:

·         Excellent video and audio quality.

·         4k recording capabilities

·         Wide angle field of view

·         Excellent low light capabilities

Cons:

·         As it’s the best webcam, it’s expensive.

Vitade 1080P Streaming Cam -The Mid Range Option

A step up from your internal web camera, not as expensive as other options on the list and it has a built in LED light? Yes please. The Vitade streaming webcam is a great option for those who want a significant improvement in terms of lighting, field of video and picture quality.

While designed for let’s play game bros who want to stream online, this camera is a surprisingly good option for online teaching. The 1080P is a significant upgrade in quality to your internal webcam, has a wide angle lens, good audio and has a light.

Pros:

·         1080P recording.

·         Built in light.

·         Works out of the box.

Cons:

·         Build quality of the device is low. Feels cheap and fragile.

·         Not a wide angle. For teaching, it’s helpful to have a wide field of view instead of the video being cropped in.

Jelly Comb 1080P Webcam – The Budget C920

The Jelly Comb webcam is a nice alternative to the more premium Logitech C920. It’s a well built webcam that offers 1080P recording, excellent audio, automatic light adjustment and a wide angle lens. What’s also great about this camera is that it’s plug and play. No need to download drivers. Works out of the box.

Pros:

·         All the features of the C922

Cons:

·         Video quality and colors are not as sharp as the C922.

Top Video Conferencing Systems eLearning Professionals Should Know About

On occasions when face-to-face communication is essential, but in-person meetings are out of the question, video conferencing systems are a valuable asset. The challenge is to find the best video conferencing system for your specific eLearning needs and budget, especially when there are so many options available. Here are the top 10 video conferencing systems that every eLearning professional should know about.

1.    Google Hangouts
Google Hangouts offers a free version that is one of the top video conferencing systems available today. However, if you plan on including more than 20 people in your chat, then you may want to consider their upgraded subscription. Hangouts Pro is just at $9 a month and can accommodate up to 50 users at once. It also boasts other great features, such as email reminders, so that you can boost your attendance rates. 

2.    ClickMeeting
If you’re looking for a video conferencing system that allows you to brand your virtual meeting space and waiting room, as well as hold moderated Q&A sessions and private chats, then ClickMeeting should be at the top of your list. They offer a 30-day free trial, and plans start at just $30 per month after that.

3.    Citrix GoToMeeting
This video conferencing system is packed with features, ranging from meeting scheduling and easy-to-create invitations to participant identification and built-in screen sharing capabilities. It is $24 per month up to 5 attendees simultaneously, or $39 per month up to 25. The convenient invitation links are a big plus, as attendees can simply click on the hyperlink to access the chat on any device.

4.    Adobe Connect
Adobe Connect offers a user-friendly interface and boasts a wide range of features such as breakout rooms, private chats, and slide sharing. You can even carry out polls throughout the eLearning course of your virtual meeting to get immediate feedback, or share documents to work on online projects collaboratively with your team members. Their subscriptions start at $45 per month. They also offer Adobe Connect Webinars for $1250 a year and Adobe Connect Learning for $3500 per year.

5.    Skype Premium
Skype is one of the most popular free chat tools. However, they also have a paid version, Skype Premium, which is $9.99 per month. Their Premium option features group calls that can accommodate up to 10 users, as well as a screen sharing tool that boosts its collaboration factor. If you already use Skype for one-on-one online meetings and want to add more participants into the mix, then Skype Premium is the natural choice. The low price point also makes it ideal for small businesses or eLearning development teams.

6.    eVoice
From conference calling to call routing, eVoice provides a wide selection of features that make it a great video conferencing system for eLearning professionals who need an all-in-one solution. Their plans start at $29.99 per month, which includes 1000 minutes of calling and 5 extensions, as well as 15 phone numbers. Their basic packages only cover voice, but their premium subscriptions include video and web conferencing. If you want to convey a more professional image, but simply don’t have the budget to set up a physical office, eVoice is definitely worth considering.

7.    Cisco WebEx
The free version of WebEx only includes voice calling, but their Premium package features voice conferencing that supports up to 8 users simultaneously. It is $24 per month or $228 annually, and boasts screen sharing tools, document sharing, and a whiteboard where every member of your team or audience can jot down their opinions and ideas.

8.    Join.Me

You just download it onto your computer and start your first meeting in a matter of minutes. They offer a 14-day trial for all of their plans, but also have a free option that features VoIP conferencing. After the trail is over, you can carry on with the plan for just $19.99 per month, which covers phone numbers and video conferencing system.

9.    StartMeeting
This option is ideally suited for webinars and online presentations, as you can host up to 1,000 users at a time. They also offer a 30-day free trial that gives you the chance to try before you buy. After that, it is $19.95 per month. However, if you want to add in video support, StartMeeting must be paired with a variety of other video conferencing systems, such as Adobe Connect, to add in the video support.

10.           Yugma
Yugma offers a free version that allows for up to 2 participants and limits the virtual meetings to an hour. They also have 6 different paid plans that start at $24.50 per year. The platform features screen sharing, audio conferencing, private chats, Skype support, and whiteboards that streamline collaboration with your team. You can also poll your audience during the meeting and add annotations.

11.                       Shooting your class in a real class scenario along with audio. This type of recording needs high sound proofing or something like a studio setup that could cost you more (although there are videos that are taken in normal classrooms, the audio will not be clear and it will be boring for your students to get them follow you)

12.                       Use a whiteboard app for your smartphone (Educreations for iOS and Explain Everything for Android or iOS). You can now use this whiteboard provided, for teaching your lesson. You can easily export it out. After exporting your teaching video from the teaching apps, you can upload as it is in the social network or you can do post effects in Adobe After Effects and mixing them with a pure audio or music in Adobe Premiere Pro. Visit an Example video

For the second method, you don’t need a camera but a good microphone (Blue Microphones Snowball), so that you can clearly record the audio after recording the visual thing in a really quiet room.

In case of first method, a dslr camera is needed to satisfy your quality. Surf for Canon or Nikon dslrs (Canon EOS 700D or Nikon 5300D). Along with the dslr you’ll need a microphone ( Samson Q1U (dynamic, $50), Samson Meteor Mic (condenser, $70), Blue Microphones Snowball (condenser, $100), Samson C01U (condenser, $120), Blue Microphones Yeti (condenser, $150), Audio Technica AT2020 USB (condenser, $150), Blue Microphones Spark Digital (condenser, $200), Rode Podcaster (dynamic, $230)), a sound card box (PreSonus AudioBox USB $150)), a good lighting (CowboyStudio 220 Watt Photo Studio Monolight Strobe Kit) and a decent sound proofing in the room your shooting.

After recording your video sesssion, you have to edit your video footage. Get a decent workstation for it (I suggest a Macbook Pro). For simple editing of your video and audio, you can try Adobe Premiere Pro. It is the simple standard video editing software and it is easy to learn and quite easy to master too.

When you get well trained in the same, you probably may think about color grading or some cool effects for making your video look professional. Then you must switch over Adobe After Effects, which is a video compositing software. You can add intro brand animations using this software.

Ofcourse, there are equivalent software in open source also quite powerful as that of the paid version. Openshot - equivalent to Adobe Premiere Pro Natron - equivalent to Adobe After Effects.

Please be aware of your resolution settings and audio quality as it will play really a massive role in gaining audience from your social networks.

I wish you still need some help.

I would like to suggest you following.
