Human Practices

Accessible Science


We have a moral duty to remove the barriers to participation, and to invest sufficient funding and expertise to unlock the vast potential of people with disabilities...

— Stephen Hawking —

Although equality is a universal human right, prejudice and perceived disabilities too often exclude people with special needs from many opportunities. Especially active participation in Natural Science is much disrupted.

We decided to challenge this status quo. To have a lasting impact, and due to the complexity of this topic, we had to focus our efforts on the needs of one group of disabled people in particular: Visually impaired people.

According to the World Health Organization (WHO), 253 million people worldwide live with vision impairments. 217 million have a moderate to severe visual impairment and 36 million are blind. In Germany, 1.2 million blind people lived in 2002. Of these, 600 live in Marburg and 150 of them are students of the Philipps University.

That is a third of all blind students in Germany!

Marburg has taken many steps to make the city more livable for blind people. You can find talking bus stops and elevators, shopping aids in nearly every supermarket and special rooms in the library of the Philipps University. One of the reasons why Marburg has become this hub for blind people is the BLISTA. It is a nationwide competence center for the blind and visually impaired. It established the first high school for visually impaired students worldwide. Nowadays, this Carl-Strehl-School is the only high school in Europe preparing blind students for higher education. Despite these ideal conditions, visually impaired students are only rarely found in fields like biology or chemistry. We intended to show that anyone believing blind people incapable of doing well in these fields is mistaken.

Therefore, the crucial role in our Human Practices project fell towards public engagement and close cooperation with the BLISTA (engl.: German Institute of the Blind) to facilitate equality and accessibility in Science. In the following paragraphs, you can see for yourself.

Self-experiment - Dinner in the Dark

Since Marburg is known as the “capital for blind people,” the bar Caveau is offering a dinner in the dark named “Finstaverne” (engl.: Sinistavern). Here you get the opportunity to experience one evening in total darkness, enjoying some food and drinks with your friends or colleagues. Compared to other such evenings the only difference is the complete absence of visual impressions. The iGEM Marburg 2018 team used this opportunity to get a feel for how everyday situations, like having a dinner, in the absence of visual impressions is affecting us.

In small groups, a waiter guided us into a room without any light sources. The first challenge was to find your place on the table without pushing anyone or anything. Because we all often rely exclusively on our eyes, the first moments without them were unfamiliar to us. Once we were sitting, we started to wonder, how big the room could be, how many people were there and which team members were sitting on the tables next to us. All these questions we tried to answer by acoustic and haptic clues alone.

Then it was time to order food and drinks. Therefore, most of us had to ask more than once what food selection was available. Some of us decided to order something that could be easier to eat without seeing it rather than soup or spaghetti. They thought eating a sandwich could be more manageable. We realized that eating any kind of food was the key challenge of this evening for most members of our team. The ones who ordered sandwiches were wondering how they lost all the toppings while eating.
After several hours, it was time to leave. Here comes the last challenge of this evening. How to pay without knowing how much money you have in your hands? Some Members were well prepared and assorted the money bills in their wallet, beforehand. Most of us did not think about that before entering the dark room and had to guess if they had picked the right bills and coins. Fortunately, the waiters were very kind and trustworthy. Being more experienced than us they were kind enough to help us with the payment.

We had a lot of fun and enjoyed our dinner on that evening. At the same time, it was impressive how you experience basic things like your food and drinks differently, if your only judge is what you feel, smell or taste. Your perception of a bar changes if you cannot see all the people around you and are limited to hear a lot of voices and conversations mixing from different directions.

It was difficult to adapt to this new situation but we all managed to eat, drink and to pay. However, this experience gave us a small insight into challenges for the visually impaired. Although we know that this experience is not equivalent to real everyday situations for people with visual impairment, it still gave us an idea of the challenges some people have overcome day by day.

Interviews: Studying Science with Visual Impairment
Interview with the Dean of Biology Astrid Brandis-Heep

Our hometown Marburg is known as “the capital of blind people” but visually impaired students can only rarely be found in fields like biology or chemistry. What could be the reasons for this? We used the opportunity to talk to Dr. Brandis-Heep, the dean of students in the department of biology.

iGEM Marburg 2018: "Are biology students with visual impairment in our department?"

Dr. Brandis Heep: “From time to time there are students with visual impairment in the department of biology. The practical work in the lab is more challenging for them”

iGEM Marburg 2018: “Are there special lab spaces for students with special needs? How do they manage to do the practical work?”

Dr. Brandis Heep: “If students need special support they can get help from assistants and besides that all our lab courses are done in groups of two or more students. The big advantage is that students can help each other. So both sides learn from each other. This would not be possible if students have to pass the courses alone.”

iGEM Marburg 2018: ”Are there special safety instructions for students with visual impairment?”

Dr. Brandis Heep: “They should be able to follow the safety instructions given to all students who work in the lab. Sometimes special instructions are necessary depending on the grade of visual impairment.”

iGEM Marburg 2018: “Are students with handicap allowed to provide a replacement if they are not able to complete a course?”

Dr. Brandis Heep: “In our department, usually every student is free in choosing the modules he or she wants to take. Students with a handicap will choose lectures and courses in the way they are able to take part. This means not all practical courses may be possible. Sometimes they need an assistant to do the practical work and so they do not need to provide replacements. They always need intensive advices before choosing a module.”

iGEM Marburg 2018: ”Are there special features that must be taken into account during the application procedure for students with visual impairment?"

Dr. Brandis Heep: “The application procedure is the same but in our experience the students get in touch with us before they start as a student at the faculty of biology. We talk about their disability and the possibilities we can offer. This gives us the opportunity for individual arrangements. For example, the lecturer can give them the PowerPoint slides, so they can follow the lecture on their laptops.”

The fact, that some students with visual impairment successfully completed their biology studies has strengthen our motivation to bring science closer to pupils of the Blista School. In a conversation with a student of the Blista School, he told us that he sometimes thinks about breaking up the high school diploma because he thought there was no way for him to study biology. He told us that he is very interested in science and especially in microbiology. However, after we told him about our conversation with Dr. Brandis-Heep and he had worked with us in the lab for one day, he gained new courage, that graduating and finding a job in this field is possible for him. It made us very happy that we were able to show people new ways to realize their dream.
We are very thankful that Dr. Brandis-Heep gave us the opportunity to ask these questions and supported us with our human practices project.

Interview with our PI Gert Bange

For several years, our PI Prof. Dr. Gert Bange mentors the iGEM Teams of Marburg. In Marburg, he is known as one of the pioneers in including students with visual impairment in scientific research. We used the opportunity to talk to him and could benefit from his experience in cooperation with visually impaired students. He told us, that he had visual impaired students working on their own project in his department. We had many questions to ask about daily lab situations.
One of our questions was, if this student was focused on doing bioinformatics or if he also did practical work in the lab. Prof. Dr. Gert Bange said that he was performing practical experiments like everyone else in his lab. We told him that some people are precarious if visual impaired students are able to work in a laboratory where they are confronted with many chemicals and different sources of dangers.Our PI answered us that of course, it is important to label some bottles and equipment in braille or with other haptic marks. In addition, it is necessary to have a well-structured and organized workspace with clearly defined places for the equipment. According to him, it did not cost much effort to prepare a special workspace for a visual impaired student because anyway lab spaces should be well organized.
He never had the feeling, that visual impairment was a barrier in daily lab work for his student. He confirmed that his students was working independent, efficient and was reliable. Prof. Dr. Gert Bange strongly believes that no matter if, someone has a handicap, everyone should get the same opportunity to show his or her expertise and knowledge.

The complete scientific community would benefit of all those talents, if we start encouraging people with disabilities to study STEM-fields. In order to do so we would like to lay the foundation stone for a scientific world without hindrances for visually impaired people with our barrier-free Wiki.
We thank Prof. Dr. Bange for sharing his impressions and experience with us and supporting our ideas.

Visit of chemistry lesson in the Carl-Strehl-School for the Visually Impaired
Students are working in groups with their customized laptops.
In the context of our human practices project, we had the opportunity to visit the chemistry lessons of a 12th grade from the Blista School for pupils with visual impairment. About 15 students were taught about the nomenclature of alkanes. The teacher catered for students with different needs using various methods. One of these methods attracted our attention when we entered the classroom. Every student possesses his or her own laptop. Asking the students, we figured out, that the school is providing laptops for each student.
Dr Tobias Mahnke explaining the content of the lesson in one-on-one conversation.
The teachers upload worksheets on their intranet and using their laptops, the students are able to use these worksheets by scaling them up or using a screen reader. Additionally, he printed the worksheets in normal print with a big font size and in braille depending on their individual handicap. Another haptic method is the usage of magnets or models in different shapes, to give the students an idea of atomic bonds and orbitals. Additionally, auditory methods were used to distinguish between different chemicals in tubes.

After the lesson, we had some time to talk to the teacher and he confronted us with a very interesting question: “How do you explain to a blind student how a flame looks and behaves like?”

This is a very difficult task because they, of course, can neither touch the flame nor hear it. Tobias Mahnke showed us how they solved this problem. With a kind of heat formable piece of paper, he is able to emulate the shape of a flame and now the students can feel where the hottest position is.

We were impressed by the different methods of teaching students with visual impairment and could learn many techniques to prepare their visit to our lab. In general, we thought back to our chemistry lessons in school and wished that our teachers also used a variety of methods and not the only visualization by sketches. It would have been a lot easier to imagine and understand the configuration of molecules and other complex topics.

It would be a big win for everyone if there could be more communication and exchange between schools teaching students with special needs and regular schools because both could benefit from each other and learn a lot, as we did during our human practices project.

Excerpt: Study Perspective for the Visually Impaired.

Governments throughout the world can no longer overlook the hundreds of millions of people with disabilities who are denied access to health, rehabilitation, support, education and employment, and never get the chance to shine.

— Stephen Hawking —

With the knowledge from our Open Laboratory Days we knew that most experiments could be adapted to remove barriers, the next logical step for us was to find out why there weren't more disabled students at our departments. What was the university politics regarding equal access to education and how were they implemented? Our university has an office of disability issues which is also responsible for blind and partially sighted students. That was the first address for us to get answers. Contacting them was easy and already in the return e-mail, it turned out that they were eager to hear about our project and the planned cooperation with the Carl-Strehl-School.

We met with them in a relaxed setting and got to ask as well as informing them that, actually, we were neither the first iGEM Team in Marburg, nor the first one to collaborate with the School for the blind and visually impaired.

The main service they provide for students is to know regulations and, even more importantly, the people in the different departments responsible for their implementation. Consequently, it is their job to provide disabled students contacts and guidance while being not directly involved. But they had a lot of useful information for us. For example, about state-funded aids for students who need assistance or additional time during exams. They also told us that the Philipps-University is the center of higher education in Germany with the highest quota of visually impaired students. We found out that the people responsible for how visually impaired students were dealt with in actuality were the same that also coordinated the whole education program in the departments.

Thinking back to our own time as newcomers at the university, knowing whom to contact is a valuable thing. Since we now knew the contact details interesting to the students, we put them together in one comprehensive list, which we provided them with. To further encourage the pupils to choose their path without fear that they stood no chance, we arranged interviews with visually impaired researchers in the middle of a Natural Science course, or that have successfully obtained a degree in their respective field. We had a bioinformatic student present, that was eager to answer questions of interested pupils.

We hope those measures will prove helpful in diminishing their concerns, since such personal reports are a bit more compelling than just our word for it. Some of us bonded with our aspiring researchers and we became personal contacts for future questions and study subjects. We hope that our efforts will start their respective science careers and that we remain a source they can rely on. Our initiative lay the groundwork for a lasting, sustainable interaction of future iGEM Teams with new generations of BLISTA pupils.

Accessible Webdesign

“The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect.”

Tim Berners-Lee (inventor of HTML and founder of the World Wide Web)
Logo for Webaccessibility

Accessibility in science does not end at providing a barrier-free lab. When getting into contact with Victor Kratz one of the topics we discussed was accessibility in the digital space. In the past years globalization and digitalization have shaped the world as we know it. Globalization is accelerated by digitalization and the internet is more important than ever before. The web has the ability to work for all people regardless of language, location, gender, age, income or ability. It removes barriers in communication and interaction that many people with disabilities face in the physical world. Yet, badly designed websites and applications can create barriers which lead to the exclusion of possible users. At this point in time e.g. a lot people with visual impairment need to adjust web pages to make them accessible to them. Barrier-free web design provides accessibility to all people regardless of ability or interface. In our conversation with Victor Kratz he mentioned that a lot of websites still are not suited to be accessed via a screen reader.

As scientist, we use the web a lot basically everyday nowadays. We’re having access to scientific publication, are doing bioinformatic analysis and can order e.g. oligos through online shops from science companies. It generally plays a huge role. Because of this, it is crucial to provide access to all those applications to everyone regardless of their abilities. A huge part of iGEM is the presentation of our work. We hold presentations, make posters and design a wiki. Habitually, we should always ask ourselves this one question: Is everyone able to access the data I’m presenting? We decided to design our wiki in an accessible manner to tackle this question. Through this, we aim to make the results of the iGEM competition accessible to everyone. And by this taking a step towards a more inclusive scientific community.

But how do you design an accessible wiki? We did some research and put together a guide for you!

Accessible Wiki - The guide
  • Navigation

    Many users rely on a keyboard for navigation. All elements of your wiki should be accessible when using only a keyboard as the navigation device. This means that you can focus on every relevant elements using the Tab key.
  • Colour and Contrast

    A high contrast between background and e.g. text should be used. This is especially important for buttons and symbols since they can’t be modified by the user. Additionally, red and green should not be used as contrasting colours since people with colour blindness can’t distinguish between those two colours. Additionally, for symbols and buttons, use a combination of colour, shape and text instead of only using colour to distinguish
    Figure showing an example graphic on how to use contrast.
  • Scalability

    Font sizes, distances,areas etc. should be set relatively so that they can be adjusted. This can be achieved by using % or em as units instead of pt or px.
    Don't:
    body {font-size: 14px}
    body {font-size: 14pt}
    Do:
    body {font-size: 14%}
    body {font-size: 14em}
    Distances should not be created using transparent pictures. Instead, distances should be formatted using HTML or CSS.
    Don't:
    Do:
  • Headers

    Headings should be defined as headings instead of defining them as . Heading should be descriptive. Instead of “Welcome”, your heading should contain important search keys.
    Don't:

    Do:


  • Lists

    List should be formatted as lists instead of using wordwraps and hyphens.
    Don't:

    List




    ...
    Do:




  • Text

    Color or font style should not be used as the sole distinctive feature. Instead use e.g. bold styles to let it stand apart.
    Don't:
    This is a text in which this word is important.
    This is a text in which this word is important.
    Do:
    This is a text in which this word is important.
    Animated text can also cause problems and should be described by an alternative text in the source code. (See Figures and Videos)
  • Frames

    Information that belongs together like navigation and content should always be shown in one frame. Otherwise, users have to switch between those frames. Frames should be named with titles like “navigation” or “content” for better orientation.
  • Figures, Videos and Audio

    Don’t only convey information using images, audio or videos. To better accommodate people using a screen reader, it is possible to add an alternative text to the source code of figures. By this, the screen reader reads the alternative tags instead of reading the filename you uploaded. This is crucial for obtaining information about the graphic.

    If graphics do not convey any information and their sole purpose is to accessorize the website you should still put a blank alt tag in the source code. By this the screen reader skips this graphic. Without any alt tag, it would read the filename.

    It is possible to check for accessibility of your wiki. In the settings of most browsers, graphics can be turned off. Image Maps should not be used, as they are only accessible using a computer mouse.

    This is an example picture of a cell.
  • Tables

    Tables should be arranged, so that they can be read row for row from left to right. Additionally, a description containing a summary that is not shown but can be read using a screen reader is helpful for understanding the content.
  • Links

    Links to other sites should be in form of a descriptive text instead of non-descriptive links, such as “click here”. If a graphic is used as a link symbol, the alternative text in the source code should point to the information the link leads to. External links should be labeled.
