Back to ex-cathedra teaching

Here am I, back from winter lectures. I have been quite busy, giving lectures in three different towns! Recently, I restructured a course completely which I have held about ten times during the last three years. The last course evaluation was the last straw that broke the camel's back.

It was a well-designed course where each participant during these two days treated two out of six topics twice actively and consumed the rest twice by the presentations of their colleagues. So, if someone was with us mentally the whole time, (s)he was well prepared for the exam in the end. However, the students disliked the course. I was accused of being lazy and incompetent. This never happens to me in the other courses which are less interactive and less demanding. In fact, it is much easier for me to come with a powerpoint presentation and talk for two days through. There can be no surprises, no difficult questions, no discussions about why this student's solution is wrong or maybe not.

I can talk for days, and talk and talk and talk. But in the pedagogic course, we learned that we must not do this. We must make the course participants work. They must do exercise after exercise and discover the knowledge themselves.

Finally, it did not work. I will forget everything I learned in this course. The students want ex-cathedra teaching. It is less risky. When they do an exercise, they assume that it is wrong anyway. And if their colleagues present something, they, too, assume that it is wrong and not worth being listened. And when they come to a course, they do not expect to learn something there. They expect that they can write their emails there and plan for the exam preparation some days later.

So, in the completely revised version, I did my presentations most of the time and a very short case study exercise in addition, to have some change. That was completely OK and they liked listening to me and taking notes and all this school-like setting.

End of the story: I am back at ex-cathedra teaching. I do not know on which weak scientific basis trainers are taught to torture their participants by making them work. When the participants do the exercises, this is mainly out of mere politeness, not because they love it. Doing an exercise creates stress for them, like an exam. There is always the risk they do something wrong and loose their face in front of the whole group. Who loves this?

I do not completely give up hope to find some really genial, innovative trick for teaching. But for the moment, it is OK for me to stand and talk all day.

Reverse mentoring

Mentoring usually means that a young person learns from someone with more experience. More experience means that there is more knowledge, and this knowledge can then flow to the person who has less.

Reverse mentoring, instead, works the other way round: The experienced person learns from the younger one. How is this possible? In German, we know the word "Betriebsblindheit" which can be translated as "routine-blinded". This means that experts have learned to see things in only one way. New, unexperienced persons see things differently. Of course, a new or different sight is not always better. But it might. And the discussion about why things are as they are, can be helpful to assure whether you really know what you are doing and whether it still makes sense, whether it makes sense in any case etc.

The term of reverse mentoring, however, is regularly used in cases where older people learn from younger about topics where the young persons really have more experience, for instance about new media.

The usefulness of gender studies: avoid traps!

I am currently implementing some key learnings from my own gender studies performed 2013. For instance, in gender studies it is found that women in informatics work on "soft topics" preferably. This might sound nice, because women have a natural gift for soft topics. But this is nonsense. I am more talented for hard facts, statistics, numbers, formulas. The soft topics are fascinating me because they are even more complex than mechnical research questions because soft skills and emotions are more difficult to measure and enhance the complexity of statistical treatment.

The harm that is done by women moving to soft topics is in that these topics have a low prestige. Producing code is valued most in informatics. This means that people who do this have a higher prestige, this work is better paid and it is easier to get funding for such work as a freelancer or as a scientist.

I wondered why this could happen that during my 20 years of work life I drifted from hard topics like programming, simulations and numerical calculations to requirements engineering. Was it a completely free choice? No. I remember jobs where suddently I was told to keep my hands from the code, in order not to damage anything. When I asked to get programming tasks, I was told this was not possible because I had never written any code before and it is too difficult for me to learn. This was not true, but prejudice beats facts. When the boss says programming is too difficult for me, I must not touch the code.

Why I write this is the following: I kept my eyes open. The world is full of opportunities and we can choose. Currently, I am preparing for a programming course, a course about IT security and for a Matlab Simulink course. Welcome back, my good old friends! Differential equations, vehicle models, graphics, DOS attacks! I am feeling like in the good old times of my studies when colourful formulas were telling me their secrets and I calculated air planes in the flight or cold metal falling into warm liquids. I am on my way back to hard topics...

Privacy Captcha: How to ecrypt optically your data

Privacy captcha is an image that can hide your data when you transfer it on an open channel. "To hide" means that it can not be read automatically (e.g. by hackers or other listeners), but only by humans. It might be a photo of your dear cat or your banc account number. Listeners will not know.
You can produce your own captcha online at https://privacy-captcha.com and then download your own captcha (by rightclicking on the image) or by downloading the software to your computer.
This service is a gift by the well-known German club digitalcourage and by The Digital Native (don't ask me who they are!).
Enclosed, you see an example:

I didn´t find it at YouTube

No, I did not leave Internet. I just was busy with the lecture start. Right now, I was verifying whether I really defined an unsolvable task when I asked a student to prepare a presentation about JAutoDoc. He said that he found nothing about it. It was not a YouTube. Ehm? In fact, there is ONE YouTube video about JAutoDoc. And finally, there are even more possibilities to do online research about JAutoDoc than YouTube. YouTube is neither a search machine nor a university library. Not all the world's knowledge is documented at YouTube, you know?
He said that if I find more than he did, then I am quite good at research. Oh yes, I am quite good at this! *grin*

Edupunks

"Don't study, teach yourself." This is the message of the edupunks movement. And my heart sais "yes" and "no" to this.

No: Before you start doing something new and creative, you should learn about what there is already. Problems, solutions, problems of the solutions, rules, alternative methods and tools. And only after you know this all, you can start developing your own solutions.

Learning the old stuff is more efficient when you trust an expert to summarize it for you and give you an overview about it. This is what your studies are for.

Yes: Of course, you are always responsible for yourself. The university can only deliver you part of the knowledge you will need for the rest of your life. This can not be otherwise because universities can only deliver basic knowledge which they believe will be useful for most of the students. When you were a professor, you would know what a small fraction of this expert`s knowledge fits into one lecture. It is frustrating for the professor, but he must make an educated choice. Especially, practical trainings and exercises take so much time. You can present UML in one hour, but really teaching it until everyone is a UML master would take several weeks of full-time teaching. And will all of them need it in this detail later-on?
So, the better you already know what job you want to do afterwards, the better you can teach yourself additionally what you will need and can focus during your studies on these topics, for instance by choosing the right lectures, seminars and internships.

I think that studies are a good basis for everything. You gather basic knowledge and learn working and learning strategies. And you get professional feedback about your performance, weaknesses and strengths. The professor has seen hundreds or thousands of students, he can compare.
But you will never stop learning anyway!

I understand that the demanding young generation who expects perfection from others, is not satisfied with their professors. I hope they will get more modest when they start working and see that they are not perfect neither and overestimated their knowledge and performance. When they start to see how much work it is to prepare a really good presentation and to give objective and competent feedback to 40 students.

My advice is: Go and trust the good old education system, but do not lay all responsibility on your professors. You are the one who knows where you want to go and what you want to learn. Set your own focus and teach yourself, too. And do not expect the professor to be responsible for your future. He has so many students!
And, by the way, it is the same for professionals: The boss and the company, they do not feel responsible for your learning and your future, neither. They are responsible for profit. So, they use you for producing profit. That`s it. Take the responsibility for your learning and future in your hands, too! This is the reason why I am able to earn my living now. While I was employed, I invested a lot of spare time and private money on learning. And now it is mainly these extra job activities that earn my bread and butter. Because in a company, you often learn to use very specific technologies not relevant elsewhere and follow company-specific work processes. Each company is a little universum on its own and knowledge from one universum might not be useful in the rest of the world. So, never stop learning!
