LinkedIn Learning – Change

The definition of the word change says: “an event that occurs when something passes from one state or phase to another”, other words that could be used are adjustment, development and modification. These are all words used daily in our vocabulary and are words that reflect what is happening within the university as a whole, but mainly within our roles.

Who else looks at their original job description and specification and can only see a few responsibilities that look similar to the work that you’re carrying out now? For me, some areas have disappeared altogether, whilst others have been replaced by new processes and procedures. People are all different, some seem to embrace change easily, whilst others stick their heads in the sand and hope it doesn’t affect them or their role. I’m one of those people who like to digest (in my own way) what’s been said and then find out more information e.g. Where do I fit into the change?  What part will I be expected to play in making the change happen? What knock on effect will it have elsewhere? Is there training that I’ll need to undertake? etc. etc.  

During this period of adjustment when we find our responsibilities have changed and we’re expected to ‘step up to the mark’ and embrace whatever is required to make these changes happen, this is described by Elizabeth Kubler-Ross as a ‘Change Curve’.  Kubler-Ross ‘Change Curve’ explains the emotions that most people go through when change is in the offering, although the original theory was in relation to the grieving process and describes 5 stages (see image below).  In business it is now applied to any kind of change.  

Stage 1, Denial were we blame others, which is preceded by blaming ourselves, “What have I done wrong?” and “Why me?”  

Stage 2, Doubt follows quickly afterwards causing self-doubt, uncertainty and confusion, this happens normally when you’re at your lowest ebb.  

Stage 3, Acceptance, the turning point, when you start to accept the change, think more rationally about everything and can start to work to solve problems that may arise to make the change work for you and others in your team. 

Once you’re through the ‘Change Curve’ it’s only then that you can start to move on, and it soon becomes the norm.  The length of time it takes for an individual to experience the ‘Change Curve’ varies from person to person and can depend on what the change is and how much this change is going to affect the person.

The diagram explains the stages of the Kubler-Ross model

I bet you’re wondering what all this has to do with LinkedIn Learning?  Well I’m not talking about the change from Lynda.com to LinkedIn Learning, although that has happened (see blog post Goodbye Lynda, hello LinkedIn Learning) but about the courses that may be of benefit that provide an insight into the processes that happen when change occurs. The courses (or individual videos if you’re short on time), look at change from different angles and perspectives, giving you the techniques to help you cope with change, before it happens, while it’s happening and how to come out the other end and to keep altering and growing until the process produces the end results. 

When you have time, just type ‘change’ into the search box, you’ll see a list of over 48,000 items will appear, this can be filtered down by using the block on the left-hand side, to make it more manageable and tailor made to your requirements. Of course the university hold workshops on this subject as well, but we don’t always have the time to attend. 

In case you were interested in the courses that I looked at, here they are:
Building Resilience by Tatiana Kolovou
Embracing Change by Todd Dewett
Managing Stress for Positive Change by Heidi Hanna
Leading Change by Gary Bolles

So go on, have a go, log into LinkedIn Learning today!

Three Useful Apps for Teaching/Learning

In this blog, I want to introduce a couple of apps that could be very useful additions to any lecturers’ teaching toolbox.

Screencastify

The first is Screencastify.  Screencastify is a lightweight screen recorder that can be used to capture your desktop and webcam allowing you to create videos that can be uploaded directly to YouTube and, at the same time, saved to your Google Drive. Being a Chrome extension means that there is no heavy weight software to download and it can also be used offline. There is a free version that limits the number of videos you can make to 50 per month with a maximum length of 10 minutes per video. However, you can upgrade to a paid for version, approximately £20 (it comes priced in dollars), which has no such limits.

Anyway, enough reading, here is a short demo of Screencastify in action

https://youtu.be/VwU-kwFzVHk

https://youtu.be/VwU-kwFzVHk

It does lack the functionality of a product like Camtasia, but if all you need is a quick easy screen recording it is well worth a go. You can also keep the videos on YouTube private by setting them to unlisted so they cannot be found in searches or as recommendations, students would just need the URL which can be made available via your Moodle pages.

Once you’ve made your video using Screencastify, you can have it as a stand alone resource available via YouTube or you could use it to produce an enhanced learning object by combining it with Adobe Spark.

I can see this having a variety of uses from giving video/audio feedback to forming part of a set of flipped learning sessions.

Screencast-O-Matic

An alternative to Screencastify is Screencast-O-Matic. As with Screencastify, this app also comes in free and licensed versions. The free version of Screencast-O-Mantic will record videos of 15 minutes which can then be saved as MP4 files, this version also comes with some limited editing functionality but does require a software download and does not work quite as seamlessly with YouTube or Google Drive.

Brainscape

The third app, useful as a revision aid, is Brainscape . Brainscape is an online flashcard system, you can either create your own flashcards or use a pre-made set. Unlike other ready made flashcard systems I’ve seen, Brainscape does have resources suitable for HE and not just in traditional academic disciplines. This system is free (though you can pay to release a larger number of cards) and can be accessed through your Google account.

As students work through the set of cards, they can rate how confident they are in their knowledge and understanding. Staff can create classes to which they can invite students, thus allowing you to view how many cards the students used and how they themselves rate their learning.

Brainscape says that its system is grounded in proven techniques that help improve learning and understanding. Not having used this particular platform myself with learners I can’t comment on the veracity of the claims made but as flashcards are a popular learning technique this online system is worth looking at, especially given the range of topics it covers.

LinkedIn Services to Support University of Portsmouth Students and Staff

On Friday October 25th we had a visit from Ralph Blunden the Relationship Manager for LinkedIn. Since 2017 the University has been using Lynda, an online resource with thousands of courses on business, creative and technical skills. Lynda had been owned by LinkedIn for sometime and this summer, Lynda moved over to the LinkedIn Learning platform. Ralph offered to present on how LinkedIn Learning and LinkedIn could be used to support both students and staff and we had a great turnout from all around the University willing to listen.

People sitting in a room facing Ralph the person from LinkedIn Learning

There are now over 30,000 courses on LinkedIn with up to 40 new ones being added every week. The new platform personalises learning by making recommendations a lot more relevant, these are based on previous learning, on what is popular in the University and if a LinkedIn account is connected – recommendations are based on the skills shown on the user’s account. When courses are completed a badge can be added to a LinkedIn profile, which is particularly useful for students in order to show employability skills to potential employers.

LinkedIn have 23 million accounts in the UK, while only around 10% of these are active at any time it represents a significant section of the working population. Around 70% of employers recruit using social media showing a professional presence for employability and making connections is essential. With Industry 4.0 and changes about to happen because of emerging technologies like AI –  skills requirements are increasingly fluid – Linkedin data shows the average skill having a shelf life of 5 years. While hard skills are still important, the most in demand skills for employers is creativity along with other soft skills such as critical thinking, being able to learn, teamwork and adaptability.

LinkedIn are aiming for their services to compliment learning for students and staff in HE. LinkedIn Learning can supplement in class learning, allow opportunities for flipped classrooms, support accreditation and professional development for staff. It can promote employability and placement skills for students and encourage engagement with alumni, allowing students to make important professional connections. 

There a number of ways we could leverage LinkedIn Learning to target certain areas by packaging courses and creating collections/playlists or utilising the existing learning paths. Teaching excellence could include blended learning, flipped classrooms, instructional design and VLE training. Digital capabilities can be packaged, staff development and employability for students also. LinkedIn offer a mapping service, where if we supply the competencies we’re looking to develop they will map the appropriate courses against them, allowing the creation of collections/playlists.

Accessibility: Investigating Automatic Media Transcription

Background

Accessibility is now an important aspect of digital learning. We need to take accessibility seriously both to satisfy the needs of an increasingly diverse student body and the requirements recently brought into law. Of course, digital learning often encompasses a wide variety of resources in a range of media. The challenge of bringing all these resources in line with regulations is considerable, both on a technical and organisational level. Fortunately technology can help to ease the burden, with a number of integrations available to help examine and fix content-related accessibility issues.

One particularly large challenge, and one that is particularly helped by the use of technology, is video. While it is possible to watch and transcribe a video manually, when faced with a library of nearly 8000 hours of video, the challenge becomes insurmountable! This is where technology can step in: it can automate the process and reduce the number of person-hours required.

For quite some time, YouTube has been able to automatically caption videos. In the past, however, the transcriptions produced by the algorithms have often been the subject of ridicule for the sometimes bizarre and hilarious interpretations. Thankfully things have moved on considerably, with increasingly advanced AI and machine learning helping to increase the reliability of computer transcription.

For the majority of our video content, we rely upon a home-spun system composed of a Wowza Streaming Media server and a custom-built front-end to manage content and metadata. While this system has the facility to allow subtitles to be added, it does not feature any way to automate the process of creating transcriptions. For this reason, we are currently investigating our options, with a view to either hosting our video content elsewhere or improving our current provision by implementing auto-transcription facilities.

The contenders

We have been investigating a few services to judge the accuracy of the transcription. We have tried each service with the same videos to see how accurately they can transcribe a variety of media content. Below are some details of three services we are currently examining.

Mozilla Deepspeech

An open-source option that can be run on-premises, Deepspeech requires a certain amount of technical skill in deploying and managing Linux servers. Being open-source and community driven, the more effort you put in, the better the output will be. It allows you to train your own neural network to increase the accuracy of transcriptions, so theoretically it would be possible to improve your transcription accuracy, although it may require a large investment of time and effort. As we are simply testing the out-of-box abilities, we have used the default models provided by the developers.

Google Speech to Text Engine

This is an API made available through the Google Cloud Platform. The service itself is used by YouTube to provide auto-transcriptions of uploaded videos. While using it through YouTube is free at the point of upload, utilising the API in your own projects can cause costs to rack up quickly (and remember that we have 8000 hours of video sitting on our servers, waiting to be transcribed). The pricing options are transparent, however, so we can easily calculate the cost of transcribing all of our existing content.

Amazon Transcribe

This cloud service is utilized by Amazon’s virtual assistant “Alexa” and works in a similar way to Google’s offering, with transcription charged based upon the number of seconds of content transcribed. The service is used by the content capture service Echo 360 to transcribe material. By our rough calculations, transcribing our 8000 hours of content through Amazon would be a little cheaper than through Google. 

The results

Here are some example transcriptions of one short piece of video content

Mozilla Deepspeech

so wee al seend apisode of the dragon tf dend where the ontroprenel holks in with a really great idea good looking numbers the dragons e recing out their hands and then one of the dragons pipes up let see your contract and os soddenly ontrepenelox exposed because they thought they had a contra they don’t what they have iser some verbal understanding your colercial contracts are really important to you business mey should be kept clear concise so the point to add value when seeking in bestment wor in ed if you come to sellin a business also commercial contracts areningportant to the void conslote because both sides of the contract should now wot their obligations are a more their rights are

Google Speech to Text (through youtube)

so we’ve all seen episodes of the Dragons Den where the entrepreneur walks in with a really great idea good-looking numbers the Dragons are eating out their hands and then one of the Dragons pipes up let’s see your contract and all the sudden the entrepreneur looks exposed because they thought they had a contract they don’t what they have is a some verbal understanding your commercial contracts are really important to your business they should be kept clear concise to the point to add value when seeking investment or indeed if you come to sell the business also commercial contracts are really important to avoid conflict because both sides of the contract should know what their obligations are and what their rights are

Amazon Transcribe

So we’ve all seen episodes of the Dragon’s Den, where the entrepreneur walks in with a really great idea, good looking numbers that dragons reaching out their hands. And then one of the dragons pipes up. Let’s see your contract over something. The entrepreneur let’s exposed because they thought they had a contract. They don’t. What they have is a some verbal understanding your commercial contracts of really important to your business. They should be kept clear, concise to the point. Add value when seeking investment, or indeed, if you come to sell the business. Also, commercial contracts are really important to avoid conflict because both sides of the contract should know what their obligations are, what their rights on.

Conclusion

As you can see from the output above, while the Mozilla software makes a good guess at a lot of the content, it also gets confused in other parts, inventing new words along the way and joining others together to form a rather useless text that does not represent what has been said at all well. I’m sure its abilities will improve as more time is spent by the community training the neural network. However, Google and Amazon clearly have the upper hand – which is not surprising, given their extensive user base and resources. 

While Amazon Transcribe makes a very good attempt, even adding punctuation where it predicts it should appear, it is not 100% accurate in this case. Some words are mis-interpreted and others are missing. However, in the main, the words that are confused are not essential to the understanding of the video.

Google Speech to Text makes the best attempt at transcribing the video, getting all words 100% correct, and even adding capital letters for proper nouns that it clearly recognises. There are options to insert punctuation when using the API, but this feature is not available in the YouTube conversion process.

From this (preliminary and admittedly small) test, it seems you get what you pay for: the most expensive service is the most accurate and the cheapest is the least accurate. Also, the headline cost of using Google Speech to Text on 8000 hours of video is not necessarily accurate. We need to remember that not all of this content is actively used: this is an accumulation of 8 years of content, and it’s possible that only a small fraction of it is still actually being watched. We now need to spend some time interrogating our video statistics to determine how much of the old content really needs to be transcribed. 

The best value compromise, if we choose to continue to host video ourselves, may be to transcribe all future videos and any that have been watched at some point in the last year. In addition, it should be possible to provide an ‘on-demand’ service, whereby videos are flagged by users as requiring a transcription at the click of a button. Once flagged, the video is queued for transcription and a few minutes later a transcription is made available and the user alerted.
