Postgrad Engineering - online course design and experience

Today Yousef Amer will be talking to us about his course redesign experience for a postgraduate course, Supply chain management.

When I started designing this online course my aim was to have my students (class size of ~70) to be engaged and to get to the point that they were interacting and sharing knowledge. To do this I used Gilly Salmon’s 5 stage model of teaching and learning online as described in these books – e-moderating and e-tivities.

The web site was simplified as much as possible. We separated the web site into two sections - Teaching and Learning. The Teaching section contained e-readers, journals, books, solutions and PowerPoint presentations. The Learning side contained the interactive elements –the discussion groups and quizzes.

Addressing Stage 1, “Access and motivation” the front page was welcoming and outlined all the main folders and features of the course site. Students were reassured and encouraged to take time to become familiar with the site and information available on it. There was one face to face lecture that demonstrated the online environment to the students. I walked them through the different components of the web sites, highlighting the critical components – 3 discussion boards. One was a lectures notice board, one was a group discussion board where students could only access their own group (~10 students) and the final one was a general discussion board. Students were shown where regular communication occurred. I also provided a consultation time for those who needed one-on-one support mostly for technical support.

Stage 2 is “Online socialization”. The first activity was to ask students to introduce themselves online and provide some background in relation to work experience and qualifications and what their aspirations were. The communication rules were also spelt out.

In Stage 3 “Information exchange” the students were required to respond to another’s post in their discussion group. This gave them the opportunity to access work from at least one other student or the entire group if they wanted to, and the chance to peer review. I used weekly online quizzes to allow the students to self-assess their knowledge of the topic and become aware of where the gaps were in their knowledge and opportunities for development. To build up and establish the groups online e-tivities were assigned two weeks apart.

Stage 4 relates to “knowledge construction” – and this is where the students were working in groups. Most groups were communicating quite well and some were already tackling the group assignment in an organised fashion.

This sense of “development’ relates to Stage 5. Students spoke more freely and expressed themselves more openly online as compared to in lecture and tutorial setting. Communication was also more immediate with some students checking the discussion board daily.

As a online teacher it was an interesting experience. You could see the groups forming through the discussion board to become active and supportive of each other – finishing by exchanging telephone numbers and meeting times. For me it was important to keep track of their contributions so that the ‘quieter’ students didn’t get left behind. This was a bit tricky at times, especially as some students have similar names. Those students who weren’t making postings were encouraged by other students and if they disappeared for too long were emailed by myself. Concerns about their expression of English was common – but after I reassured them that they were not being assessed on spelling and grammar, that they became more active in the discussion.

The student evaluations of these learning experiences has been very positive particularly the way that this learning can be applied in real situations.

Wikis in Engineering

Today we have Liz Smith, from the School of Advanced Manufacturing and Mechanical Engineering, to share some of her experiences using wikis to support student project work in different courses.

We have used wikis in Engineering for the past couple of years. A couple of examples include....

In 2008 we used PBwiki with the common first year course Sustainable Engineering Practice. The students used the wiki as a place to create an online portfolio of assigned tasks. The tasks were focussed on developing the student's understanding of the engineering profession. This included collecting three on-line news articles on engineering and sustainability and commenting on each article and how it related to sustainable practice; collecting two on-line job advertisements for graduate engineering positions and summarising the attributes for which the employer was looking; developing a career plan map and discussing how the student planned to manage their ongoing professional development; reporting on the industry speakers who presented throughout the course and preparing a resume. Each of these tasks was approximately 200 word equivalents.

For more information on how we used PBwiki and what the students thought about it, check out our paper:
http://www.ojs.unisa.edu.au/index.php/atna/article/viewFile/378/288

And here are our presentation slides from the ATN Assessment conference 2008:


In 2009 we used PBwiki for the second year course Mechanical Engineering Practice. The major assessment task for this course is the Weir Minerals Design and Build Challenge. This challenge is for nominally second year mechanical engineering students working in groups. To assist in working collaboratively, each group were required to use a wiki to simulate an engineering design file. In their wiki, students collated information related to the project, such as drawings, calculations, and meeting minutes.

It was hoped the wiki would help students work collaboratively. Here is a link to our example wiki http://meng2009-coordinator-2009.pbworks.com/

The benefits of using the wiki, as identified by the students include: the flexibility of uploading information at home, sharing and storing files in one location, displaying images and videos, and the ability to provide feedback on each other’s contribution. However, even with the wiki, the preferred channels of communication between group members were via phone and email, where email was the preferred method to share documents between group members. The benefits of using the wikis, as identified by the teaching staff include: indication of group progress, avenue for providing formative feedback and identification of group members who are not contributing.

Course Coordinators regularly checked each group’s wiki and provided formative feedback on its content. Students then used this formative feedback to further improve their wiki site. Although the formative feedback was appreciated, students’ comments suggest they would prefer regular summative assessment tasks based on their wiki to keep them on track.

Overall, I really like using wikis. I particularly like using PBwiki as you can create private wikis for free. Other wiki tools such as Wikispaces require you to pay a monthly amount to keep the wiki private.

After using PBwiki in 2008, I declared that I would never use PBwiki as my wiki tool again. But, since then they have updated the software so that it has more functionality and easier to use (it also has a new name PBworks). So when deciding on which wiki to use in 2009 I chose PBwiki – better the devil you know...

This is not an advertorial for PBwiki, it is just my wiki of choice. There are plenty of wiki tools availble, a good comparison of the different wikis available can be found here:

How wikis work?

Wikis can be a fast and easy way for students to work collaboratively and be more active in their learning.

Wikis have been available for a few years now as free software, some of which that have been supported by LTU's Online Education Support Team. However, wikis are also embedded in the e-Portfolio learning tool, PebblePad (webfolios), and they will become 'mainstream' from 2010 within our new UniSA Learning Management System, (LMS), Moodle.

A UniSA research project is looking at how UniSA staff have been using wikis in their classes and would like to know why academics have selected wikis, how they prepare, support and assess students, and what the students experienced within the wiki learning environment. They aim to create a framework that can be applied generally to help staff use wikis to support student collaboration.

The research is being conducted by Tangi Steen, Dale Wache, Jo Hanisch and Kirstin Wache primarily using short (10 min) anonymous online surveys. If you are planning to use wikis in your teaching in 2009 then please consider contacting Kirstin Wache to register your interest.
