Last week I was called in at short notice to record a video to promote the university internationally. Our award winning filmmaker set this up in a lecture theatre, as it was raining outside. The camera was pointing out the door into the open plan area to provide some atmosphere. So I was looking to the front of the room. We did not have an autocue, so I brought up the script on the large screen at the front of the room. I could see this over the camera operator. If I did not have an electronic copy of the script, I could have used the document camera on the lectern to project from paper. Might be useful for ad-hoc recording.

Sitting in a meeting discussing ways to provide audio for team teaching and events at universities. Rooms are normally equipped with a couple of microphones for teaching. But for more active classes, and events, there may be a half dozen people speaking. Buying professional grade microphones gets expensive.

There are Bluetooth lapel microphones for around $100. But other small units designed for making ordinary headphones wireless, at about $20.
The output from multiple Bluetooth microphones could be received by a laptop, or tablet computer and combined using a mixer app (with no additional hardware required). Anyone know of such a setup, please let me know.

ANU Techlauncher Learning to Reflect Introduction
Today I had the delight of being in a classroom with the Australian National University's Techlaucher students, as well as those joining online (video available). Normally I stick to the mechanics of how the "Learning to Reflect" module I supervise is run. The staff of ANU Careers provide the actual content, running students through exercises to help them think about a career. However, after reading Becoming by Michelle Obama, I was inspired to talk a little about my own career. The point wasn't big-noting myself (well not entirely), it was to show a career is rarely a straight linear path. I happened to join ABS, just as they had millions of dollars for IT training I joined the DoD computer division only to have it abolished ending up in the nation's military HQ. I nominated for VP of the ACS, but ended up President. I joined ANU to do research and ended up teaching. The latest coincidence is that I went to an ACS meeting last night, and it was the launch of the new version of a computer job analysis used in Techlauncher. The person launching it happened to have an interest in training computer people in Indonesia, as do I ...

Tools for Creating Educational Videos With No Video Editing
From my arrival in academia, 20 years ago, I have been looking for a way to create multimedia educational content without having to record and edit video. In the early days video took a lot of bandwidth. The networks have become faster and the compression technology better, but this can still be a problem for some students (and staff). Also video take considerable time and skill to produce. I don't lack the skill (I learned video production for training at the Canberra Institute of Technology, back when it was ACT TAFE). But I do not want to spend my time lining audio up with video clips. What I have aimed for was something like slides with an audio commentary.
As an early attempt I used a system which would play an audio file and synchronize this with HTML content. That works but was not really stable enough to be usable.
For the last two years I have been using Vidnami, which appears to have been developed more for marketers, than educators. With this I provide a script in the form of plain text and the system finds suitable stock video and images, creates synthetic audio, an option music track and makes a video. Normally I would substitute my own presentation slides for most, or all, the stock footage (which can be a bit silly at times).
I use the synthetic voice videos to supplement text based notes and live events. This works well for the flipped classroom. I can easily produce a video to accompany the notes for students to study before a live class (be it face to face, online or a hybrid of both). A video recording is also made of the live class for later review by students and for those who could not attend.
However, Vidnami has been sold for integration into GoDaddy Studio. So I have been looking for an alternative. Vidnami helpfully provided a list of video product suggestions, but as they say, these don't quite do the same thing.
There are many text to speech systems available, some which integrate into Powerpoint, but most sound like robots. And with standalone systems, you still have to manually add the images, which is very tedious.

Temporary Webinar Studio
The mattress is queen size and resting on two chairs. The chair I sit on is between them. This keeps the mattress in place and also curves it slightly, providing extra absorption of background noise from the side. I use a headset microphone to further reduce noise.
This worked fine for the first webinar in my new series "Engaging students in the online environment" in the Microlearning Series at Maskwacis Cultural College, Canada.
There are specially designed booths used for podcasting from offices, using sound absorbent foam. However, a simpler setup, with an acoustic panel of the type used for office partitions, curved and mounted on wheels might work well in a shared office.

Learning to Reflect Module Version 3.0 the 2020 COVID-19 Pandemic Edition
"Learning to Reflect" is a module for the ANU TechLauncher program developed in late 2018 and first run in semester 1, from February 2019. This was designed for blended delivery, with the option of easy conversion to full online delivery. That option was needed for Semester 1, February 2020 due to COVID-19,. The two face to face workshops were replaced with Zoom video conferences. The online content and activities were unchanged.
The assessment was removed from two online quizzes and forums, leaving just two assignments to provide 20% of Techlauncher assessment. This was done in an attempt to reduce the burden on students, and staff, who were suddenly required to change from face-to-face to online learning. The students still had their tutors at Zoom video-conferences, to help them keep up with their studies.
About 90% of students still completed the quizzes, despite them not counting towards assessment. In contrast, about 90% of students did not post regularly to the online forums. The difference may be because the quizzes were quick and easy to complete, being multiple choice, whereas the forum posts required composing text. Also the quizzes returned instant feedback in the form of connect/incorrect and a numeric score, whereas there was no automated feedback in the forums. When the forums are assessed, there is feedback from students (which is also assessed). However, some form of tutor-bot might be useful to give instant feedback.
A paper on the design and blended delivery of the module is available:

It should also be possible to offer both classroom and online real-time (synchronous) sessions for students. This would use the same software as for distance education, but tied into the classroom's audio-visual system. There should be no need for any special additional hardware or software.

Problems with Using Flipped Classroom a Programming Course
![]() |
| Hrafn Loftsson, Reykjavik University |
"Abstract— The use of the flipped classroom (FC) approach and team-based learning (TBL) has gained popularity in recent years by instructors in introductory programming courses (CS1), due to increased emphasis on student success and active learning. In this paper, we present an experience report about using FC and TBL in a CS1 course. We present the motivation for restructuring the course, the specific implementation, the results of two student surveys, and the outcome of several exams. We discuss the results, present what actions were taken during the course period, and what changes will be carried out in the future. The results from the surveys show that 47% of the students were pleased with the organization of the course, whereas up to 33% of the students were displeased (in particular the female students). About 60% of the students liked the TBL in class, but about half of the students felt that the course lacked traditional lecturing. Finally, it was surprising that 44% of the students never or seldom read the textbook before class, while 74% watched the videos."The results were surprising, in that students admitted they tended not to read the textbook (not surprisingly, they did watch the videos). Many students did not like the elimination of lectures (even though many students do not turn up when lectures are offered). The satisfaction level and completion rate was lower than previously. In response the externally sourced videos where replaced with ones featuring the instructor and shown at the start of each face-to-face session, and the number of programming exercises the students have to hand in was reduced. This restored the student satisfaction ratings, and the successfully completion rather also went up to around the university average.
At question time, I suggested that the in-class individual quizzes be administered before the face-to-face class, rather than during it. This is to encourage the student to read the materials provided and watch the video. In contrast another delegate suggested having the quiz at the next face-to-face class, to give the student more time.

A wall of screens is not the classroom of the future
![]() |

HD screens and cameras are now not reasonably inexpensive, so it is tempting to fill classrooms with them. However, we should use the technology to overcome the limitations of physical classrooms, not perpetuate them.
If each student is displayed on screen life size, then this is only going to work for a small class, of less than one hundred students. For hundreds of students you would need a huge wall, and the instructor would not be able to clearly see any of them. Also the students in the room can't easily see the remote ones, even in a small room for a hundred students (in Colorado State's example, the screens are behind the students). This would accurately emulate a large lecture theater, where the instructor can't see most of the students clearly, and students can't see each other, but is that a good thing?
| Plan of Jeremy Bentham's panopticon prison, drawn by Willey Reveley 1791. From Wikipedia |
The obvious solution is not to try to mimic the bad features of a physical classroom. Rather than dozens of screens, just have one on each wall, with the image of whoever is speaking enlarged, and everyone else reduced to thumbnails. This is what readily available, cheap or free, videoconferencing software already does. It is what most of the students in “Room of the Future” see anyway, as they do not have a wall of screens at home.

Learning to Reflect Module Version 2.0
Introduction
The notes and videos contain content intended for instructors, as well as students, to be used in conjunction with online exercises, and face-to-face workshops. Students will be prompted by the Moodle Learning Management System, as to which parts to read, and when to read them.
1. Learn
In this first of two parts, you will investigate what you need to learn for your project, and long term for your career. In scope here, are both technical skills and also professional and teamwork skills. The aim is to prepare you to be a professional in your field, which includes the ability to take charge and responsibility for your future professional development.
2. Report and reflect
In this second and last part, you will reflect on what you have learned. The assignment task is to select a real position to prepare an application cover letter for, and revise the responses to selection criteria prepared in assignment 1.

Learning to Reflect Videos
Having revised the "Learning to Reflect" module notes for ANU TechLauncher students, it was time to revise the video. This is a time-consuming and exacting process, even for someone with training in video production.
Last semester I produced this by first making a slideshow presentation, which was also used live in the classroom. I prepared a script based on what was in the module notes, rearranged to match the sequence in the video. I then turned each slide into an image, and the script into synthetic speech. The slides and audio were then imported into a video editing package and timed to match the audio. The results were not perfect, but like Samuel Johnson's piano playing dog: "It's not done well; but you are surprised to find it done at all." ;-)
This time I decided to try Content Samurai, after it was demonstrated at PitchEd NSW. This is a web based tool which takes a script, and searches for suitable video clips, or still images, based on the key phrases. The service will then turn the script into synthetic speech timed to the video. This process works remarkably well. The Australian accented male voice provided is much better than those I have used previously. I did have to slow down the narration to 80% of full speed, and lower the volume of the background music to 5%.
I then changed the settings, to use only still images, and have one per paragraph, with no animation, or scene transitions:
One problem was that rendering was very slow (but video rendering is always slow). I found it could be faster by using still images, rather than video clips. The rendering took about six minutes for a six minute video. Also I created a plain black template for the slides, with no shaded pattern.
One option I would like is to reduce the bit-rate of the audio. For an educational video you need only low quality mono sound.
One tip is to set your slide maker (I use LibreOffice) for 16:9 format slides, to match a modern widescreen TV. Then generate the slides images at the resolution required. Full HD TV is 1,920x1,080. Content Samurai produced the lower resolution 1,280x720HD TV format typically used for broadcast TV, but down sampled my higher resolution slides very cleanly.
I could not find a way to prepare closed captions within Content Samurai, so I uploaded the video to YouTube, and then downloaded the VTT file it produced. I then uploaded this to the Moodle website, for the students.

Learning to Reflect Course Module Worked
This is the tenth of a series of posts, on how to provide students with help when preparing a reflective portfolio. A class of 78 graduate computing students completed the module, as part of ANU Techlauncher. The flipped, blended, peer assessed approach worked well, and produced outcomes comparable to conventional lectures with instructor assessed assignments. A copy of the updated course notes are available. I can also provide a Moodle backup file including all course materials, and quiz questions, to instructors.
In 2008 I decided to stop using lectures as part of university courses. I then spent 2009 to 2018 designing and delivering purely online courses. In February 2019 the Australian National University unveiled the Marie Reay Teaching Centre, a flexible teaching building. I was able to use the building to try out the approach of an online course supplemented with face to face workshops. This I suggest could be generally applied in higher education. I have submitted a paper on this to an international computer education conference.

Audio Slideshow for Job Application Reflection Module
This is the ninth of a series of posts , on how to provide students with help when preparing a reflective portfolio. This is an audio slideshow. The slides are based on the course notes and the audio is computer generated.
This is intended to be a demonstration of how to produce multi-media for education, quickly, and easily. The slides were produced using LibreOffice "Impress" (a free alternative to Microsoft Powerpoint). To generate slides suitable for HDTV, the presentation was exported as PNG images at 1280×720 pixels. These slides were copied into the KDEinLive digital video package, and adjusted to fit with the audio commentary. The video was rendered as 720p MPEG 4, at 200 kbps, 24 frames per second, with 64 kbps audio.
The computer generated audio is monotonous, and the text based slides not very interesting. However, this is a good start before trying anything more ambitious. Also students are not undertaking study to be entertained, but to be educated.
ps: This is for students of ANU Tech Launcher.

How to Blend and Flip a Course for a Flatpack Classroom
In 2008 I ended my last lecture for the year at ANU by announcing it would be my last lecture, ever. Having become disillusioned with the lecture format, I have been teaching online for the last ten years, with an award winning course offered by three institutions, in Australia and North America. During that time I looked at alternative classroom designs in Australia and around the world.
In February 2019 the Australian National University unveiled the Marie Reay Teaching Centre, a flexible teaching building. So this year I am going back to the classroom, to apply what I have learned, with a blend of online and classroom teaching in the new building. This is intended to be a model for how academics can easily convert conventional courses to new interactive ways of learning, and allow each student to choose the blend of online and classroom learning to suit their needs.
Overview of the Learning Module
I produced slides, and a video for the revised learning module, on how to provide students with help when preparing a reflective portfolio. This is for students of ANU Tech Launcher, but intendeds to be able to be used more widely. The module has two parts, with the same format: read the notes, do an online quiz, participate in an on-line forum with peer assessment, then a face-to-face workshop, lastly do an assignment with peer feedback.
New Flexible Teaching Spaces at ANU

In contrast, the Marie Reay Teaching Centre has only flat floor classrooms, for 30, 60, or 120 students. The flexibility here is provided by retractable walls, furniture on wheels, and electronic screens on multiple walls.

In contrast, the ANU Kambri complex has two buildings with specialized seating for specific pedagogy. The ANU Cultural Centre Building has high density tiered theater fixed seating for lectures. Opposite is the Marie Reay Teaching Centre with low density flat floor movable seating and tables for group work. This has the advantage that both format rooms can be used simultaneously. and offer a greater overall seating capacity, than would general purpose lecture/group rooms.

Top Down Course Design
The learning is designed top down: start with the learning objectives, or externally set requirements. These set, in broad terms, the knowledge and skills the student must have on completion of the course. Often these objectives are not provided to the educational designer, or are so vague they are of little use, so they have to be found, or invented.
"Upon completion of this module, students will be able to:
From the skill "Learning and Development" (ETMG), Level 6, SFIA, Version 7, 2017. As used in "Learning to Reflect" (Version 0.1), February 4, 2019.
- Determine their own learning needs and possible sources, to develop individual skills for a project and for their career development.
- Identify appropriate accreditation and qualification paths.
- Manage the learning, and evaluate its effectiveness through through reflection."
"The module is aligned with two of the outcomes for the course:
3. 'learn any specific technical skills required by their topic, and apply them to project work.4. apply and deepen skills in oral and written communication, and apply these in a project context.'From Computing Project, Course COMP8715, ANU, 2019. URL https://programsandcourses.anu.edu.au/course/comp8715" as cited in "Introduction", of Learning to Reflect, Version 1, February 13, 2019.
Aligning Assessment with Leaning
Chunky Blended Learning
Designing learning takes time. I started designing the learning module in late 2018. At that time I was not sure if the new classrooms would be completed for first semester 2019. Even the week before semester started in February 2019, there was construction equipment around the building. However, this was quickly cleared away and the building opened on time, with the classroom equipped.However, in late 2018 I could not be certain everything would be ready. So I used a conservative approach to blended course design, using what Fleck (2012) refers to as "chunky" blended learning:
'The term "blended learning" usually refers to a mix of conventional face-to-face elements combined with on-line elements. However, this is at too general a level for in depth analysis, while the term "blend" perhaps suggests too homogeneous a mix: in practice the mix is more "lumpy", more a chunky fruit salad than a blended smoothie. At one extreme it is becoming routine for campus-based virtual learning environments (VLEs) to be used to provide additional notes and materials supporting conventional lectures.'
From Fleck (2012).The design is essentially a distance education course, with face-to-face workshops added. The learning management system (LMS), in this case Moodle (part of ANU's Wattle system) is used for providing students with course notes, videos, podcasts and other materials. The LMS is also used for routine announcements to the class, and individual communication with students. Small assessment tasks (quizzes and forum posts) are provided via Moodle's quiz and forum modules. Assignments are similarly done using the workshop module of Moodle.
The same format is used for all workshops, so that staff and students can become familiar with it. This avoids limited class time being taken up with explanations of complex exercise formats.
- Announcements: General announcements while students set up the room.
- General Questions: Students can ask for clarification on administrative, content and assessment questions. Groups first discuss the question and if they are not sure of the answer it can be put to the whole room.
- Forum Questions: Discuss your answers to this week's forum questions.
- Assignment Master Class: Bring along your draft assignment, ask for feedback from your group. Be prepared to put it up on the big screen for group feedback.
- Wrap-up: Any concluding remarks by students and instructors.
Chunky Online Learning
As well as the blended and online learning being chunky, the online component is in large chunks. The student is provided with a package of material for two weeks. This has notes, suggested readings, a quiz, discussion questions, workshop, and assignments. While the student is expected to undertake the work in this order, exactly what they do when in the two weeks is left largely to the individual.This contrasts with tightly scripted online learning modules which give the student a few paragraphs to read and perhaps a video, then an automatically marked question they have to answer before proceeding to the next item. Such packages require considerable design and testing if they are not to hold up and frustrate students. Also these tend to require a high speed reliable network connection to function. In contrast the chunky approach allows students to download material, and use it offline.

Shorter Learning Module for Teaching Students to a Write Job Application
Previously I provided three parts (1. Plan, 2. Learn, & 3. Report and reflect). However, that was far more work than a student could do in the available four hours study. So I have deleted part 1. Some of the content on learning has been moved to the next part "Learn", but the rest has been deleted. Also I have made all readings "suggested", not required. The SFIA learning objectives have been replaced with two from ANU Techlauncher (which the module is part of).
Also I have added a video with commentary to introduce the module, and audio podcasts for parts 1 & 2. The audio is text-to-speech, using Animaker's Australian English voice "Russell". I am not that good a speaker, and it would take a long of time to come up with a good narration. As it is, I can copy the notes to a text file. I then insert pauses at the ends of paragraphs, and replace abbreviations (such as "ANU", which would be pronounced as "Arrnoo"). I can simply edit the text and regenerate the audio, in a few minutes.
