Project presentation


As the readers of this blog may remember I had chosen MS Excel as the technology for using in my Mathematics class.

I had a three pronged logic for using this technology with the primary reason being using something different to perform mathematical operations.

Excel was used by the students to learn how to do Numerical Differentiation. Traditionally we had taught this topic using pen and paper. My assumption was that the students would find the usage of technology beneficial as it will help them in doing the calculations plus the convenience of making any changes in the formulae without losing any work as well as eradicating any incorrect uses of formulae.

Once I introduced the idea to my class about using something different to solve these differentiation problems, most of the students were enthusiastic about it. However there were a small minority who still preferred the pen and paper method. However by the conclusion of the topic they too were convinced that Excel did make the solution of these problems easier.

To record the success, or otherwise, I asked one of my students, Khalifa, to give a crash course to his peers. One of the students then made a video of this presentation using his cell phone and it is available at


This is another example of using a technology in class as the students can view the video of any learning or teaching at their leisure for after hours help.

Looking back, I think the experiment was a success it made the students' learning easier and hence my job too.

I am so convinced of using Excel for such problems, that in the upcoming semester I would use it to teach the whole of the Numerical Techniques learning outcome, of which Differentiation was just a part.

21st Century Learner


The article “Teaching the 21st Century Learner” brings out some valid points about the difference between the learners of the present and those of yesteryears. It points out the technological developments that have taken place in the recent years and how it has impacted on the lives of the younger generation. It also discusses the changes that can be made to make learning more attractive for the modern student.

“Authentic Learning for the 21st century” focuses on how learning can be enhanced by focusing on real life problems and how the knowledge gained can help with their solution. The method to incorporate these lifelike scenarios in the preset learning scheme is by using technology. The author then further elaborates on how various forms of technology is being used at different institutions around the globe to amalgam these concepts into their teaching process. Lastly the article discusses the effectiveness and importance of such learning methodology.

 I do tend to agree with most of the points raised in these two articles. It is indeed true that learners and their perceptions towards learning have changed and hence it is imperative for educator to adapt to the mode of delivery of learning. Educational technology has become as integral part of the learning-teaching process and it is found to be utmost beneficial for the learner in the 21st century.

Gamification - An interesting read

The article by Rick Raymer makes interesting reading as it compares educating to game play in video games. I find this comparison amusing for two reason. Firstly, for most of our studying at home competes for time with lots of other activities, video games being one of them. Hence we are taking inspiration from one of the competitors. Secondly, I myself am a gameaholic so i could relate to almost all the terminology and scenarios that the author mentions.

Couple of ideas that I found worth using are as follows

The non linear progression of courses can provide students with flexibility and will give them more control over their learning ability.

The measurement of progress using graphics or character upgrades is something that will catch on with the students very easily and I think they would be able to relate to it better.

Literature discussion

Amongst the three articles that I had short-listed, I found the research done by Abbasi and Iqbal to be interesting enough to share. Their research was conducted to find out the ratio of mathematics educators at post/under graduate level in Pakistan, who make the mathematics courses livelier for their students.

They chose three criteria namely dedication, logical reasoning and concrete examples and use of technology to measure the interest a course can generate amongst the students. The reasoning for using dedication as a criterion, given in the research is also very interesting. The researchers have concluded that if the educators proclaim their passion and dedication towards the subject in front of their students, it has a positive effect on the students’ motivations levels and moral.

In conclusion they researchers have shown that the correlation of using technology in class to the students’ perception of the educators’ attempt to make their course interesting is just about 99%. It is closely followed by the logical reasoning and concrete examples at about 98%.

A few questions though remain unanswered from this article. For example the authors have not defined the terms "interesting", "dedication", "logical reasoning" etc. Secondly the authors do not show a correlation between making the course interesting and it enhancing the understanding of the students. We can assume it has proportionality but yet a deeper insight into it would have been beneficial.

I tend to agree with their research in general since I am a strong believer in making “boring” courses to be more “student friendly”. This helps to catch the students’ attention and somehow it can help the learners to see the same content from a different, more interesting vantage point hence creating a genuine curiosity, ultimately leading to a better understanding.

Mobile technologies


The article “Role of mobile digital technology in fostering the construction of pedagogical and content knowledge of mathematics” by Mohan Chinnapan discusses the findings of a research conducted on the uses of smartphones for sharing mathematics concepts and pedagogies with a peer. It also looks at the types of representations and models that can be constructed using a smartphone.

Although the research was conducted with teacher at a primary school level, the facts hold true for higher education too. Smartphones can be used not only as a tool to discuss and share material with fellow educators as well as the students. The biggest advantage I can see in this regard is the capturing of visuals (still or moving) of real-life engineering mathematical phenomena. One example that I can think of in this regard is the mixing of two streams of a fluid which are represented in mathematics by a tangent hyperbolic function. Another good example is the rate of change of volume of an inflating balloon which is an application of partial differentiation.

Smartphones can only be used to make videos of peer tutoring that takes place between students informally in a classroom. These videos can then be shared with the rest of the groups and peers for future referencing and access.

Students can also use smartphones to take audio snippets, images and videos of how certain complicated mathematical problem are solved in class. This can save the student the time spent copying and he can concentrate on the understanding of the solution. Again sharing and retrieving these files are as easy a click of a button.

The email and messenger facilities on the smartphones provide instant sharing opportunities with all the stakeholders and the extended memories of these handsets can store data which can be used throughout the study period.

MS EXCEL and EGEN N301


I am teaching Engineering Mathematics IV (Code EGEN N301). This is the final course of mathematics that engineering students take during their under graduate studies. The course introduces concepts of statistics, probability and three dimensional geometry. It also builds upon the calculus knowledge of students from their previous courses by teaching the applications of calculus. Lastly this course covers topics involving numerical techniques.    

The assessments for this course include 3 CR exams worth 25%, 25% and 30% each. The remaining 20% grade is available for quizzes, assignments and homework and it is up to the prerogative of the teacher.

I would like to use MS EXCEL in this course for teaching the numerical techniques more specifically teaching numerical differentiation. For numerical differentiation the students have to find the values of the function at specific interval for a particular value of the function and then to compare its value with by finding the derivate of the function and then replacing the given value of the variable.

There are three methods that are taught during numerical differentiation namely forward difference, backward difference and central difference and the student has to employ all three along with the normal differentiation to find the values of the function.

Although the three methods are fairly similar, the complexity of the function makes it into a cumbersome process and the students tend to struggle in doing these four calculations correctly all the time.

In my opinion it would be a case of learning with technology rather than learning from technology. As Jonassen mentions, technologies should function as a tool kit which support the required intellectual functions of the course.  

The biggest advantage of using MS EXCEL would be the eradication of memorizing and introduction of understanding. I think this will enhance their deeper understanding of the content. It will also improve their problem solving and critical thinking skills since helping them in finding their mistakes more quickly and efficiently, saving them time they would have otherwise spent if they were solving it using the conventional pen and paper method.

The students will be expected to work in groups of three. They would be taught how to progam formulae and functions in MS EXCEL. I intend making a video of this session so it can be used for any students who miss the class or would like extra help. This video can also be used for future teaching of this topic.

MS EXCEL and Calculus - What do the others say?

While searching for educational uses of MS EXCEL, I came across many interesting articles and papers.

Here's a sneak peek of what the most interesting ones talk about.

Abbasi and Iqbal did some research on the proportion of mathematics educators at post/under graduate level in Pakistan, who make the mathematics courses more livelier for their students.

How and why


The course where I intend using technology is the final engineering mathematics for semester students.

The last learning outcome of the course involves numerical techniques which involve solving differential equations and derivatives numerically, amongst other sub learning outcomes.

My biggest reason for using technology is to give the students a taste of something different. Traditionally these topics are covered using pen and paper but with the usage of technology, I am sure the students will find it more interesting.

Secondly, number crunching plays a major part in solving numerical technique questions and there are always chances of hitting the wrong button on the calculator. These kind of mistakes be reduced as EXCEL with do most of the arithmetic operations.

One powerful help that EXCEL provides is prompting for incorrect formulae input which otherwise the students will not be able to find out easily.

Typically I would give a mini test to the students on these topics which would last 45 minutes or so and most of that time is spent by the students on calculators. Using EXCEL will reduce the time consumed in this regard too.

In conclusion, using EXCEL will test the students’ understanding of the concept of these numerical techniques with them not getting penalised for their lack of proficiency with a calculator.

Learning networks


I can consider myself blessed that I have been a part of a learning network throughout my engineering career. That goes to show that a) Engineers are a helpful lot. And b) that that field is so vast we need help from each other, always.
My informal learning network was actually formed during the student days at UNISA and it has had additions with passing time. It became international as I studied in Europe and even more diversified as I found employment here in Dubai.

The level of contact with this bunch of people is varied and dependent. My colleagues at wotk are always there to help, advice and support. I am still in touch with my chief engineer from my previous employer, an expert in fluid mechanics, both socially and professionally. Other members of the network are contacted professionally as need arises.

The tools used for keeping are the usual social media and email although I love the face to face interaction with the colleagues.

Lastly the importance of these informal groups cannot be denied. You always have someone to lean on or to share your knowledge and experiences.

MS EXCEL - Can it do it??

I have been told by a lot of experts that MS excel is a very powerful tool when it comes to performing complex mathematical operations.

My own expertise in Excel is limited to adding up the grades of the student every semester and calculating the averages.

So I would like to use MS Excel to teach numerical techniques including differentiation & solving differential equations, perhaps even more.

The experts better be right!!

Teaching Engineering Mathematics: The new fashioned way

Traditionally mathematics at the higher end of the engineering matrix is still taught and assessed in the good old way. Pen, paper, whiteboard, etc etc.

I want to use technology in teaching (& not only assessing) at least one learning outcome.

My hypothesis is that the students will find this approach to be different and hopefully will enhance their learning experience.  

Re-Introduction

My fellow PGCTHEians

I must say it feels good to be back.

Module one was very informative and here's to hoping that module 2 is even more.

My brushes with educational technologies as an educator have been varied with sharepoint and BB vista being the usual suspects.

As a learner I also had interaction with on-line assessment and assignment submissions and accessing tutoring videos (from MIT) and course material.

Talking about "The Ten Fundamental Reasons for technology in education", I concur with all the reasons mentioned there. In my opinion the biggest benefit technology provides is the flexibility to a student's learning.
