Be Inspired by Successful Teen Role Models

Be Inspired by Successful Teen Role Models

For students whose parents are engineers, scientists, or who have friends or family friends in these roles, it is easier to picture themselves in that role. When students have good role models of scientists, problems solvers, and engineers as a part of their daily life, they see that as a path they can follow to do the same. When most people you know have gone to college, you also assume that you will go on to college.

Be Inspired by Successful Teen Role Models

But what about those students who don’t have those role models in their everyday lives?

Many of our students are from a poorer demographic, don’t have friends and family who are very educated, don’t speak the dominant language etcetera, and may have a more difficult seeing themselves in this role. As they grow up they may not even think that being an engineers, scientists, or other type of educated professional, having a patent, or being a ‘leader’ in this sense is an option or a possibility for them.

How do we fix this problem?

As teachers, I believe that part of our role in education is to show students examples of people similar to them who have been successful as engineers and scientists, even through non-traditional paths. Several scientific inventions have been made through hard work on a different path, or even through an accidental discovery that led to a greater invention.

Sometimes this can be through being that role model, as outlined in this article. It also helps build connections. The author states that “Students can sense that I understand their experiences, that I’m rooting for them, and that success in whatever field they choose is within their grasp.” There are several articles, such as this one, and this one that emphasize this idea of students benefiting from having teachers whose background is more similar to their own.

What if we are not from a minority group?

If this is not our personal story, however, we can help present students with success stories, even if they are not our personal story. I don’t believe it is only minority teachers who can help bring this benefit to a classroom of minority students. It has been shown that “Good Teachers Embrace Their Students’ Cultural Background.” In fact, in a study of high achieving urban environments, some of the deciding factors were the “development of a belief in self, supportive adults, interaction with a network of high-achieving peers, extracurricular activities, challenging classes such as honors classes, personal characteristics such as motivation and resilience, and family support” as cited in this article. As teachers, we can help support these skills and qualities. When we bring examples of pictures of scientists into class, it is critically important that they look like our students. This idea is further explored in this article, the authors state that reading acts as both a window and a mirror…. “mirrors in that they can reflect on children’s own lives, and windows in that they can give children a chance to learn about someone else’s life.” Additionally, “while it may be ideal for children to actually meet people from different backgrounds [or from a similar background, but with a different ending] in person, if that isn’t possible, books can serve as a first introduction to an outside world.” The article does a great job of explaining the importance of introducing students to these examples. This is the idea behind the book Wonder Woman, by Sam Maggs, explored in this article “Why it’s so important for girls to find role models in female scientists.

This is all a part of being a teacher too. We need to help students see that science is more than the type of science in the textbook for which they are graded and tested, and that it is something accessible to them. We can do this by showing them examples. As you bring in famous scientists to talk about in class, new articles to use, or other examples in class, make an effort to showcase people of various backgrounds. It adds value to both the students, and to the class as a whole!  Some great examples are William Kamkwamba, Deepika Kurup, and Trisha Prabu, but there are many more out there! Utilize them in your class with your students!  See how they react!

Can I Really Be a Scientist?


You may think of your students as ‘scientists’ and you may even refer to them as scientists.  But what do they think a scientist is?  Do they consider themselves scientists? 

Reflection on How Students View Scientists; and Themselves

Draw a Scientist

Many of you may have done or seen the ‘draw a scientist’ activity.  If you haven’t heard of it, it is an activity where students draw their idea of "a scientist doing science." The exercise surfaces students' prior understandings of the nature of science and the demographics of scientists.

Unfortunately, the results show that many students don't see themselves as scientists. According to an article written in 2018, students are still primarily drawing white males as scientists. Over the past 50 years the number of female scientists being drawn has greatly increased, but is still only 28%.   The authors of this article stated that “stereotypes of scientists not only shape ….perceptions of who is a scientist, but also influence their perception of who can be a scientist.”  The researchers also mentioned that these stereotypes go beyond gender, 79% of the scientists drawn were white.

This is a problem.  This is a especially a problem for minorities, females, foreign students, etc.

When we are teaching students who don’t match this image (who are female, darker skin colored, etc) it is even harder for them to see themselves as scientists.

Why is this important?  

This puts students one step farther away from what we are trying to teach them.  This is yet another way that they feel disconnected from school, and feel that it doesn’t apply to them.
We are teaching students science, and we want them to see themselves as part of science, and the scientific process.  However, many students don’t see science as relevant to their own lives. They science as only a subject in school that they need to pass, but they are, in fact, not part of it.

This couldn’t be farther from the truth.  Science should be relevant to students’ lives. Science involves problem solving from everyday life, their own bodies, and the world around them.  However, this is not always what students see.

As educators, part of our role ideally is to help bring students to a place where students can see the connections to their own lives.

Your Challenge

I challenge you to try the “Draw A Scientist” lesson with your own students. It can be a quick activity that takes 10 minutes at the end of class, or a full blown lesson.  I’d love if you’d report back with the results. Are your students drawing white male scientists? Are they drawing scientists that look like them?  It would be really cool to have some discussion or reflection to go along with this.  Lastly, what if you showed some other examples of minority or female scientists and then had them draw?  Would you get different results?

If I taught elementary I would absolutely read them this book first and see if it changed my results.  Maybe I would read it to high school too?

Try it out!

Five Evidence-Based Study Strategies Your Students Should Be Using

Five Evidence-Based Study Strategies Your Students Should Be Using

Spring and early summer brings tests and exams for many students and teachers. If you’ve managed to cajole your kids into putting in some time outside of lessons, congratulations!

The bad news, though, is that left to their own devices, most students will be using ineffective study methods, meaning they will fall short of the marks and grades they could otherwise have hit.

The good news is that there are some simple evidence-based strategies that can transform how effectively your students study, and the grades they are therefore able to achieve. Read on to find out how.
Five Evidence-Based Study Strategies Your Students Should Be Using

  1. Retrieval practice: memory training

After almost a century of research, the results are in: there is now broad consensus among learning science researchers that the best study techniques are based on “retrieval practice” (see here or here for reviews). Most students study by pushing information into their brains – re-reading, highlighting, summarising, making notes – retrieval practice flips that on its head, and says they should be spending as much time as possible trying to pull information out of memory, trying to remember it.

There are plenty of options for using retrieval practice to study for tests:
  • Training with flashcards
  • Answering “quiz” questions
  • Writing down all you can remember about a topic on a blank sheet
  • Having a friend / family member test you
The key is to move on from the “pushing information in” stage sooner than feels comfortable, and spend as much time as possible studying by trying to remember what you know. It feels like harder work, but it’s far more effective.

Formative assessment is also a great discipline to use in your classroom as starter or exit activities: Science In The City has plenty of assessment resources available to life a bit easier.

      2. Spaced learning: conquer “forgetting”

Over time, we all forget what we once knew – even if we used retrieval practice to learn it! Spaced learning is the solution: for every new occasion on which your students revisit a fact or concept, their memory of it gets stronger and more permanent.

Try and get your students in a “little and often” habit: rather than cramming all the day before a test, far better to spread that same amount of study time out (or even do slightly less!) over a longer time, e.g. 10 minutes a day for a couple of weeks, rather than two hours the night before.

They will not only perform better on that test, but their knowledge will be much more secure, helping them build on it in future, rather than having to start seemingly from scratch in each new school year.

     3. Chunking: data compression for memory

“Chunking” is the act of grouping a larger number of units of information – letters, words, phrases, numbers – together in meaningful ways to create a smaller number of units, making the information easier to remember. It’s your brain’s version of data compression algorithms that make files smaller for storage in computer memory.

Here’s an example of chunking in action: 18 random letters are very hard to remember, but re-order and add some grouping, and it becomes much easier.

An example of chunking content to remember it more quickly and easily

You probably remember your own phone number by “chunking” the digits into groups. When someone else groups the digits differently, it can be hard to recognise even your own number!

Chunking is at the root of a many mnemonic techniques, such as:

Acronyms: making a new word from the first letters of the words you’re trying to remember, e.g. “HOMES” for the five Great Lakes (Huron, Ontario, Michigan, Erie, Superior)

Acrostics: making a memorable phrase from the first letters of words you’re trying to remember, e.g. “My Very Excellent Mother Just Made Us Nine Pizzas” for planets

Chunking numbers with patterns: look for arithmetic relationships to make digits more memorable. Thulium was discovered in 1879: you can derive the “7” and “9” by subtracting and adding the “1” to the “8”, respectively.

You could spend a moment in lessons working with your students to come up with a novel chunking strategy, which not only helps them learn the content, but trains them in how to use chunking for themselves. See here for an in-depth guide to using a number of useful chunking strategies, with more inspiration on how to apply the technique to a range of information types.

     4. Dual coding: we are all visual learners

Have you heard of “learning styles” – visual, auditory, kinaesthetic? You may also have heard that there is very little scientific evidence that teaching in each individual’s preferred style helps them learn.

However, it seems while we all have our preferences, we all have a bit of every “learning style” in us, and that appealing to multiple styles at once can help us to learn.
The idea of dual coding is that by taking in information as both words AND a diagram / picture, you’re more likely to remember it – perhaps because you’ve got two different ways to remember that information when you get into the test.

If your students are making summaries ahead of an upcoming test, they might like to use a picture AND a description in words for key concepts, to help solidify their understanding and memory.

     5. How to read (no, really…)

OK, so this is more about test-taking than studying: but how many times have you seen students throw away marks by not reading the question accurately?

When we read, our eyes move in jumps called “saccades”, with a focus point every few words. The brain fills in the words in peripheral vision based on word shape and context. That makes it very easy to miss things, especially under the pressure of a test!

Example of how to read most effectively for studying. Can you spot the error?

If you know what you’re looking for, it’s painfully obvious, but if you don’t, a lot of people won’t spot the two “As” before “single step”.

In one example where students were taking test questions, researchers found that emphasising a key command word in a question by switching to a bold typeface increased the proportion of correct answers from 8% to 31%. That’s huge!

You may not be able to change the test papers, but there’s a simple solution: train your students in the disciple of reading questions slowly, deliberately and methodically, using their pen to underline key words in the question to add emphasis for themselves – to make sure they pick up every mark they deserve.

Wishing you and your students every success in any upcoming tests and exams!
