Critical thinking is a term often thrown around the teacher’s lounge. You often hear, “Of course, teaching critical thinking is essential.” However, in that same space, we may also hear the question, “But how?”

Teaching students to think critically involves helping them to develop a critical mindset. What exactly does that mean, and how can we do that?

What does it mean to think critically?

Critical thinking is a complex process that involves students reflecting, analyzing and evaluating ideas. Building a community of critical thinkers in our classrooms involves going beyond the cognitive domains and building the affective domains.

The cognitive domain concerns subject knowledge and intellectual skills, whereas the affective domain involves emotional engagement with an idea or learning material.

This deliberate teaching of critical thinking needs to be part of our teaching toolkit. We need to develop a mindset around it in and out of our classrooms.

How can teachers develop a critical-thinking mindset?

Consider all the questions we pose to students during our classes. Do we expect a yes or no answer, or have we established a classroom environment where students offer considered reasons for their responses?

By following some guiding principles, we can get into the practice of naturally expecting deeper answers:

  1. Students need to engage in critical thinking tasks/activities at all levels.
  2. Teachers need to provide space/time in the classroom to build critical thinking learning opportunities.
  3. Practicing critical thinking must be incorporated throughout the course, increasing complexity as students improve their critical thinking ability.
  4. Students must be given opportunities to practice transferring critical thinking skills to other contexts.

Activities to foster critical thinking in the classroom

Activity/Strategy #1: Categorizing

Provide a set of vocabulary terms or grammatical structures on the board (or pictures for true beginners). Ask your students to gather in pairs or small groups and have them categorize the list. Ask them to be creative and see how diverse the categories can be.

Example:

Desk, computer, pencil, stove, dishes, forks, novel, cookbook, sink, shelf

  • Made from trees: pencil, novel, cookbook, desk.
  • Made from metal: fork, stove, sink, etc.

Activity/Strategy #2: What’s the problem?

Provide students with a short reading or listening and have your students define a problem they read or hear.

Tomas ran up the steps into Building A. The door was closed, but he opened it up. He was very late. He took his seat, feeling out of breath.

  • Determine why Tomas was late.
  • Underline verbs in the past tense.
  • Create a beginning or ending to the story.

Activity/Strategy #3: Circles of possibility

Present a problem or situation. Consider the problem presented in strategy #2 above: Ask the students to evaluate the situation from Tomas’ point of view, then, from the teacher’s point of view, and then from his classmate’s point of view.

This activity generates many conversations, and even more critical thinking than you can imagine!

Activity/Strategy #4: Draw connections

Provide students with a list of topics or themes they have studied or are interested in. Place one in the center, and ask them to draw connections between each one.

Afterward, they should explain their ideas. For example:

“Energy and environment are affected by sports. Most sports do not harm the environment, but if you think about auto racing, it uses a lot of fuel. It can negatively impact the environment.”

Activity/Strategy #5: What’s the rule?

Play students an audio clip or provide them with a reading text. Draw students’ attention to a particular grammatical structure and ask them to deduce the rules.

Activity/Strategy #5: Establishing context

Show your class an image and put your students in small groups. Give each group a task. For example:

The Jamestown settlement in the United States
“A famous historic site is the Jamestown Settlement in Virginia. People from England were the first people to live in Jamestown. When did they arrive? They arrived in 1607. They built homes and other buildings. They looked for gold, silver and other materials. They sent the materials back to England. It was a hard life. Jamestown wasn’t a good place to settle. The winters were cold, and the settlers didn’t know how to protect themselves. After some time, they traded with the Native Americans, including tools for food. This helped the hungry settlers. Did many people die? Yes, many of the first settlers died. Later, more settlers arrived in Jamestown. It wasn’t easy, but in the end the settlement grew.”

Ask questions like this:

  • If this were in a movie, what would the movie be about?
  • If this were an advertisement, what would it be advertising?
  • If this were a book, what would the book be about?

There are many other wonderful strategies that can help build a classroom of critical thinkers. Getting your students accustomed to these types of tasks can increase their linguistic and affective competencies and critical thinking. In addition to these on-the-spot activities, consider building in project-based learning.

How can you incorporate project-based learning into your classroom?

Project-based learning often begins with a challenge or problem. Students explore and find answers over an extended period of time. These projects focus on building 21st Century Skills: Communication, Creativity, Collaboration, and Critical Thinking.

They also represent what students are likely to encounter when they leave our English language classes.

An example project

Consider this project: Our cafeteria is outdated. It does not allow for food variety, or for guests to sit in groups of their desired size and activity level. Survey students who use the cafeteria. Follow up the survey with interviews. Determine how your group can reimagine the cafeteria. Prepare a proposal. Present your proposal.

You can imagine the amount of language students will use working on this project, while, at the same time, building a critical mindset.

Teaching critical thinking is all about building activities and strategies that become part of your teaching toolkit, and your students’ regular approach to problem-solving.

    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.
