Critical thinking is a 21st century skill that has been around for thousands of years. There are records of Socrates using critical thinking skills in his teaching in 4th century BC Greece. In recent years though, critical thinking has again become more prominent in education.

What is critical thinking?

Critical thinking requires students to do more than remember and repeat information. Instead, it encourages them to analyze, examine, evaluate and use their problem-solving abilities through questioning, theorizing and rationalizing to have a deeper understanding of the world around them, both inside the classroom and beyond.

Why is critical thinking so important?

In the past, success in education was largely based on the ability to remember facts and figures. However, the skills which our students need today go further than memorization. With our rapidly evolving technology, the internet, and the bewildering amount of information online, it is essential that our students can use higher-order thinking skills to analyze and assess the information they are presented with.

How can you incorporate critical thinking into your classes?

Devising long-term goals

We all know the importance of looking ahead and planning for the future. We can encourage this skill in our students and directly relate it to their learning.

At the start of the course, take a moment to chat with each student individually and ask them to identify an objective for the first part of the year. You may like to brainstorm possible objectives as a class first, but it’s important for students to determine their own personal objectives, rather than imposing objectives on them.

During the first half of the year you can talk to each student about their progress and ask them to assess to what extent they’re achieving their goals.

The key point comes at the end of the semester when students evaluate their progress and set a new objective for the following one.

Analyzing

The ability to analyze options, risks and opinions will help your students in the future in many situations, including when they decide which course to take at university or which job to take.

You can practice this skill by providing students with relatable situations and asking them to analyze and compare the options.

For example:

Imagine you are taking a trip with some friends this summer. You have a number of different options and want to discuss them before finalizing your plans. Talk to a partner about the different trips and decide which would be best:

  • Traveling around Europe by train for a month ($1,000)
  • A weekend hiking and camping in the countryside ($200)
  • A weekend break in a big city, with shopping, sightseeing and museum trips ($500)
  • A week-long trip to the beach in an all-inclusive resort ($650)

Anticipating consequences

Students also need to have an awareness of the consequences of their actions; this is a skill which is transferable to making business decisions, as well as being important in their everyday lives.

To practice this skill, put students into small groups and give them the first part of a conditional sentence. One student completes the sentence and then the next student adds a consequence to that statement.

For example:

Student A: If I don’t study for my English exam, I won’t pass.

Student B: If I don’t pass my English exam, my parents won’t let me go out this weekend.

Student C: If I can’t go out this weekend, I’ll miss the big football match.

Student D: My coach won’t let me play next year if I miss the big match.

Rearranging the class menu

By giving students more responsibility and having them feel invested in the development of the lesson, they will be much more motivated to participate in the class.

Occasionally, let students discuss the content of the day’s class. Give them a list of tasks for the day, including how long each will take and allow them to discuss the order in which they’ll complete them. For larger classes, first have them do it in pairs or small groups and then vote as a whole class.

Write on the board:

  • Class discussion (5 minutes)

The following tasks can be done in the order you decide as a class. You have five minutes to discuss and arrange the tasks as you choose. Write them on the board in order when you’re ready.

  • Check homework (5 minutes)
  • Vocabulary review (10 minutes)
  • Vocabulary game (5 minutes)
  • Reading activity (15 minutes)
  • Grammar review game (5 minutes)
  • Speaking activity (10 minutes)

Take this one step further by asking your students to rate each activity out of 10 at the end of the class. That way, you’ll easily see which tasks they enjoy, helping you plan more engaging lessons in the future.

    5 STEAM myths debunked

    By Sarah Hillyard
    Reading time: 4 minutes

    STEAM (Science, Technology, Engineering, Art and Maths) sounds like an overwhelming combination of subjects to teach – and only suitable for expert educators. But the reality is doing STEAM is simpler than you think. Here are 5 common STEAM myths and the truth behind them. We also outline a number of simple activities you try with your students.

    1. STEAM requires a lot of time

    STEAM projects encourage curiosity, creativity and collaboration in the classroom – but they have a reputation for being preparation-heavy and for requiring a lot of teaching time and energy.

    But to get the full benefit of STEAM, there’s no need to plan out a full-blown project that lasts a whole month. In fact, you might integrate just one STEAM lesson into your syllabus. Or a lesson could contain a one-off 10-minute STEAM challenge.

    Here are some easy, low-preparation challenges your classes can take part in:

    10-minute STEAM challenges:

    • Winter unit: How tall can you build a snowman using paper cups?
    • Shapes theme: Using five toothpicks make a pentagon, two triangles, a letter of the alphabet.
    • Bug project: Can you create a symmetrical butterfly?

    2. You need fancy materials to do STEAM

    The biggest misconception is around technology. When you think of STEAM, you might imagine you need apps, computers, tablets and robots to teach it successfully. It’s true that you will certainly find STEAM challenges out there that involve extensive supply lists, expensive equipment, knowledge of programming and robotics.

    However, in reality, you probably have everything you need already. Technology doesn’t have to be expensive or complicated. It can refer to simple, non-electronic tools and machines, too. Think funnels, measuring cups and screwdrivers, for example. You can use low-cost regular classroom or household items and recyclable materials that learners' families can donate. Toilet paper rolls and cardboard boxes are very popular items in STEAM.

    Here is a low-tech activity you can try:

    Combine engineering, art and math using cardboard and a pair of scissors

    This challenge involves creating 3D self-portrait sculptures in the using only cardboard. First, teach about parts of the face by observing and analyzing some Cubist portraits (eg, explore Georges Braque and Pablo Picasso). Then have learners cut out cardboard shapes and make slits in them to attach together. They create their self-portrait sculptures by fitting the pieces together using the slits so that the final product will stand by itself. Display the self-portraits and talk about them.

    3. STEAM is targeted to older learners

    Young children are naturally curious about the world around them, and STEAM experiences begin very early in life. They explore with their senses and test their hypotheses about the world, just like scientists do. Much of their play is based on engineering skills, such as building houses with LEGO® bricks. They learn to manipulate tools while they develop their fine motor skills and their awareness of non-electronic technology. They use dramatic play and enjoy getting their hands full of paint while engaged in art. They learn about maths concepts very early on, such as size (big and small toys), quantities of things, and even babies start using the word “more” if they’re still hungry.

    Check out this simple STEAM experiment to learn about plants and their needs.

    How do plants eat and drink?

    Have students put water and food dye in a pot. Put a white flower in the water. Ask students to guess what will happen.

    After a few days, students should check their flowers and observe how it has changed color. They must then record their results. Extend the experiment by asking if they can make their flowers two colors.
