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.

    English is the international language of business and a foundational skill for many roles. The right level of English proficiency is key for individuals and businesses to excel.

    But what is the “right” level?

    English is not a one-size-fits-all skill. Customer Service Representatives need different English skills to IT Systems Managers. Senior staff will often need more advanced English skills than junior staff.

    Forgetting to remember – What active recall is all about

    By Heath Pulliam
    Reading time: 5 minutes

    Heath Pulliam is an independent education writer with a focus on the language learning space. He’s taught English in South Korea and various subjects in the United States to a variety of ages. He’s also a language learning enthusiast and studies Spanish in his free time.

    Almost everyone has studied for a test at some point in their life. Have you ever studied a lot for a test and still not received a great grade? Probably so. This is because not all study methods are created equal. Just because you’ve ‘studied’ doesn’t necessarily mean that the material has stuck in your brain.

    Some common study methods don’t do as much as you might think. One technique, however, stands out for its efficiency and effectiveness. It’s called active recall, and it’s regarded by many as the best way to study.

    What is active recall?

    In short, active recall is the process of pulling information from your brain without prompts. The idea is that when you force yourself to remember something, you memorize it much faster than you would by only reading material or passively studying.

    When you’re taking a test and you’re not sure about an answer, you search your brain for the answer; that’s active recall. The action of trying to remember is what essentially crystallizes the information in your head for the long term. Multiple study methods use active recall or the action of searching your brain for an answer.

    Active recall forces you to pull information from your mind. It’s not just for doing well on tests but also for long-term retention.

    Active recall is praised for its effectiveness, but it is also mentally taxing. Attempting to recall things that are not in the front of your mind is tiring, which is part of why some opt out of using it.

    Dr. Cal Newport, author of Deep Work, says:

    “It’s almost like you have a pseudo-photographic memory when you study this way.”

    Passive and active study

    Most people are taught to study, but less about how to study. People end up using passive study techniques, like rereading material or rewatching lectures. Although not particularly effective, studies show that reading and rereading notes remains university students’ most common study method. (Dunlosky, 2013).

    These methods might feel like effective studying but aren’t really helping much. Yes, passive study methods such as reading, highlighting, or watching can help, but can also give you a false sense of understanding.

    With these methods, when the time comes to retrieve the information, you struggle to recall it because it is not in your long-term memory.

    The first step to becoming excellent at studying is understanding how important active study methods are, such as flashcards, practice testing, or practice teaching – all methods that use active recall.

    Spaced repetition

    If you’re researching study methods, you’ve probably encountered the term spaced repetition. This technique can be incorporated into active recall study methods, primarily flashcards.

    Spaced repetition involves reviewing information at increasingly longer intervals in order to improve long-term memory. You are using this technique when you learn something, so review it a day later, then a week later and then a month later. It helps fight your brain’s natural process of forgetting things.

    Combining spaced repetition with active recall is always a recipe for successful study.

    So, what methods can you use to employ active recall in your study sessions?

    Summarize what you know

    The simplest way to practice active recall is to try to remember the material actively. To do this, read or reread some material, then take some time away—take a walk, snack break, or whatever you like to do to take a break.

    During this break, try to replicate in your mind as much about the topic from scratch as if you had to teach about it. Don’t be discouraged if you have trouble remembering; part of the learning process is forgetting material and then remembering it.

    When using this for language acquisition, make up relevant sentences and translate them into your target language. What type of vocabulary were you learning? What grammatical structures were new to you?

    Take a mental note of which elements you were able to remember and which ones gave you trouble.

    When finished, go back to the material and review. Were you able to remember things? Whether you could or not, you’ve helped yourself. Your attempt to remember is you practicing active recall.

    When you do successfully remember something, you’ll realize that it is locked in your long-term memory. This method is as simple as it is productive.

    Teach a friend

    Similar to mental summarizing, after studying, find a friend and do your best to explain the topic to them. Language learning could involve explaining how a new grammar pattern works in your target language or taking sentences and phrases and translating them to a friend.

    As a teacher, your best lessons are the ones where you know the material inside and out. If you can effectively explain and teach someone about your target language, you are that much closer to mastering the information yourself.

    Flashcards

    Flashcards, especially when combined with spaced repetition, are the king of study methods for language acquisition.

    Between all that they can be used for, they are especially good for language learning, no matter what part of the language you’re studying. This is one of the best ways to learn sentence structure that does not mirror your native tongue, conjugations for speedy use and general vocabulary.

    I have found that using a spaced repetition-based flashcard program is the best way to study a language. This way, you don’t have to schedule a bunch of paper flashcards manually.

    Among the most popular programs for language learners is Anki. Anki is a spaced repetition flashcard program. With it, you create your cards and the program schedules them at increasingly longer intervals. It is also used widely among students studying for large tests, like medical and law exams.

    To make the best flashcards, make them yourself. Downloading a big set of flashcards for your target language is tempting but not particularly helpful. Instead, after each study session, make a few flashcards yourself covering the new vocabulary/grammar you’ve just learned about.

    One more thing: do not use multiple-choice answers for your cards. Active recall happens when you produce information without prompts or assistance.

    Personally, I use flashcards every day to learn Spanish through . This program has a learning curve, but the payoff makes it worth it.

    Test yourself

    The goal of studying for a test is to be able to answer questions about a topic or, even better, know the material for real-world application. As stated earlier, active recall happens during testing, so why not use this form of active recall before testing?

    Use your materials to make a mock exam in this method, then take it. Through actively remembering to answer each question, the ones you get right will stick in your brain. Review the questions that you couldn’t remember and retake the test focusing on them.

    While not particularly complicated, these tips and methods’ effectiveness comes from their use of active recall. As you forget information and pull it from the depths of your memory, you solidify it for yourself.

    Forgetting plays an important role in learning something for long-term memory.

    Now, get to studying; how are you going to use the power of active recall in your routine?
