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.

    Being bilingual can help keep your brain in good condition

    By Steffanie Zazulak

    Learning and understanding a new language is one of the most challenging things that your brain can do. But as well as the advantage of acquiring another language, it appears that the effort of giving your brain a good workout today by being bilingual could keep it in better condition in later life.

    Research led by Dr. Daniela Perani, a professor of psychology at in Milan, found that people who speak two or more languages seem to weather the ravages of Alzheimer’s disease better compared to people who have only mastered one language. Alzheimer’s is a progressive mental deterioration that can begin in middle or old age due to generalized brain degeneration.

    The study involved 85 people with Alzheimer’s – half of whom spoke both German and Italian and half who spoke only one language. The researchers found that bilingual patients had greater connectivity in key brain areas. This was especially in the part of the brain that governs “executive control” – a set of necessary behavioral cognitive processes that include problem-solving, working memory, reasoning and attentional control. The study also noted that the bilingual Alzheimer’s patients showed less severe symptoms of the disease.

    The study concluded: “Our findings suggest that the effects of speaking two languages are more powerful than both age and education in providing a protection against cognitive decline.”

    Bilingualism and the brain

    Although Alzheimer’s disease is currently incurable, the study supports a popular theory that people who have higher levels of education function longer with little manifestation of the illness. Part of the reason why bilingual brains may be better at resisting Alzheimer’s could be due to a lifetime of switching between languages daily.

    Learning and speaking more than one language changes how the brain carries out tasks that require focus and concentration on a certain piece of information without being distracted. It can also increase the density of white matter (connections) in the brain, meaning that there are more connections between brain parts, thus making this part of the brain more resistant to degeneration.

    This is supported by a study conducted by a team led by Professor Ana Inés Ansaldo at the , which suggests that bilingual people have more robust and more efficient brains compared to those who only speak one language. This is one of the reasons why a bilingual brain can be a buffer against aging and dementia.

    They recruited elderly people, half of whom spoke only one language and the other half who had learned a second language between the ages of 11 and 18. All performed equally well on a task that involved focusing on an object's color while ignoring its position, but brain scans revealed a big difference in how they processed the task.

    “While bilinguals were recruiting very specific brain areas and a small number of areas to perform the task, monolinguals were recruiting a much larger number of areas that were consuming much more resources. And the networks they were using were very, very complex,” says Professor Ansaldo. “That led us to think that the bilingual brain was more efficient in terms of the amount of resources that bilingual people require to do complex tasks as opposed to the monolingual brain.”

    The study concludes that bilingualism shapes the brain in a different way or how people approach complex tasks. It could be because bilinguals must inhibit the language they are not using to focus on the one that they are using.

    5 of the strangest English phrases explained

    By Steffanie Zazulak

    Here, we look at what some of the strangest English phrases mean – and reveal their origins…

    Bite the bullet

    Biting a bullet? What a strange thing to do! This phrase means you’re going to force yourself to do something unpleasant or deal with a difficult situation. Historically, it derives from the 19th century when a patient or soldier would clench a bullet between their teeth to cope with the extreme pain of surgery without anesthetic. A similar phrase with a similar meaning, “chew a bullet”, dates to the late 18th century.

    Use it: “I don’t really want to exercise today, but I’ll bite the bullet and go for a run.”

    Pigs might fly

    We all know that pigs can’t fly, so people use this expression to describe something that is almost certain never to happen. It is said that this phrase has been in use since the 1600s, but why pigs? An early version of the succinct “pigs might fly” was “pigs fly with their tails forward”, which is first found in a list of proverbs in the 1616 edition of John Withals’s English-Latin dictionary, A Shorte Dictionarie for Yonge Begynners: “Pigs fly in the ayre with their tayles forward.” Other creatures have been previously cited in similar phrases – “snails may fly”, “cows might fly”, etc, but it is pigs that have stood the test of time as the favored image of an animal that is particularly unsuited to flight! This phrase is also often used as a sarcastic response to mock someone’s credulity.

    Use it: “I might clean my bedroom tomorrow.” – “Yes, and pigs might fly.”

    Bob’s your uncle

    Even if you don’t have an uncle called Bob, you might still hear this idiom! Its origin comes from when Arthur Balfour was unexpectedly promoted to Chief Secretary for Ireland by the Prime Minister of Britain, Lord Salisbury, in 1900. Salisbury was Arthur Balfour’s uncle (possibly his reason for getting the job!) – and his first name was Robert. This phrase is used when something is accomplished or successful – an alternative to “…and that’s that”.

    Use it: “You’re looking for the station? Take a left, then the first right and Bob’s your uncle – you’re there!”

    Dead ringer

    This phrase commonly refers to something that seems to be a copy of something – mainly if someone looks like another person. The often-repeated story about the origin of this phrase is that many years ago, people were sometimes buried alive because they were presumed dead – when actually they were still alive. To prevent deaths by premature burial, a piece of string would supposedly be tied to the finger of someone being buried – and the other end would be attached to a bell above ground. If the person woke up, they would ring the bell – and the “dead” ringer would emerge looking exactly like someone buried only a few hours ago! Other stories point to the practice of replacing slower horses with faster horses – “ringers”. In this case, “dead” means “exact”.

    Use it: “That guy over there is a dead ringer for my ex-boyfriend.”

    Off the back of a lorry

    This is a way of saying that something was acquired that is probably stolen, or someone is selling something that’s stolen or illegitimate. It can also be used humorously to emphasize that something you bought was so cheap that it must have been stolen! “Lorry” is the British version – in the US, things fall off the back of “trucks”. An early printed version of this saying came surprisingly late in The Times in 1968. However, there are many anecdotal reports of the phrase in the UK from much earlier than that, and it is likely to date back to at least World War II. It’s just the sort of language that those who peddled illegal goods during and after WWII would have used.

    Use it: “I can’t believe these shoes were so cheap – they must have fallen off the back of a lorry.”

    11 ways you can avoid English jargon at work

    By Steffanie Zazulak

    From “blue-sky thinking” to “lots of moving parts”, there are many phrases used in the office that sometimes seem to make little sense in a work environment. These phrases are known as ‘work jargon’ – or you might hear it referred to as ‘corporate jargon’, ‘business jargon’ or ‘management speak’. It’s a type of language generally used by a profession or group in the workplace, and has been created and evolved over time. And whether people use this work jargon to sound impressive or to disguise the fact that they are unsure about the subject they are talking about, it’s much simpler and clearer to use plain English. This will mean that more people understand what they are saying –both fluent and second-language English speakers.

    The preference for plain English stems from the desire for communication to be clear and concise. This not only helps fluent English speakers to understand things better, but it also means that those learning English pick up a clearer vocabulary. This is particularly important in business, where it’s important that all colleagues feel included as part of the team and can understand what is being said. This, in turn, helps every colleague feel equipped with the information they need to do their jobs better, in the language they choose to use.

    Here, we explore some of the most common examples of English jargon at work that you might hear and suggest alternatives you can use…

    Blue-sky thinking

    This refers to ideas that are not limited by current thinking or beliefs. It’s used to encourage people to be more creative with their thinking. The phrase could be confusing as co-workers may wonder why you’re discussing the sky in a business environment.

    Instead of: “This is a new client, so we want to see some blue-sky thinking.”

    Try saying: “This is a new client, so don’t limit your creativity.”

    Helicopter view

    This phrase is often used to mean a broad overview of the business. It comes from the idea of being a passenger in a helicopter and being able to see a bigger view of a city or landscape than if you were simply viewing it from the ground.Second-language English speakers might take the phrase literally, and be puzzled as to why someone in the office is talking about taking a helicopter ride.

    Instead of: “Here’s a helicopter view of the business.”

    Try saying: “This is a broad view of the business.”

    Get all your ducks in a row

    This is nothing to do with actual ducks; it simply means to be organized. While we don’t exactly know the origin of this phrase, it probably stems from actual ducklings that walk in a neat row behind their parents.

    Instead of: “This is a busy time for the company, so make sure you get all your ducks in a row.”

    Try saying: “This is a busy time for the company, so make sure you’re as organized as possible.”

    Thinking outside the box

    Often used to encourage people to use novel or creative thinking. The phrase is commonly used when solving problems or thinking of a new concept. The idea is that, if you’re inside a box, you can only see those walls and that might block you from coming up with the best solution.

    Instead of: “The client is looking for something extra special, so try thinking outside the box.”

    Try saying: “The client is looking for something extra special, so try thinking of something a bit different to the usual work we do for them.”

    IGUs (Income Generating Units)

    A college principal alerted us to this one – it refers to his students. This is a classic example of jargon when many more words are used than necessary.

    Instead of: “This year, we have 300 new IGUs.”

    Try saying: “This year, we have 300 new students.”

    Run it up the flagpole

    Often followed by “…and see if it flies” or “…and see if anyone salutes it”, this phrase is a way of asking someone to suggest an idea and see what the reaction is.

    Instead of: “I love your idea, run it up the flagpole and see if it flies.”

    Try saying: “I love your idea, see what the others think about it.”

    Swim lane

    A visual element – a bit like a flow chart –  that distinguishes a specific responsibility in a business organization. The name for a swim lane diagram comes from the fact that the information is broken up into different sections – or “lanes” – a bit like in our picture above.

    Instead of: “Refer to the swim lanes to find out what your responsibilities are.”

    Try saying: “Refer to the diagram/chart to find out what your responsibilities are.”

    Bleeding edge

    A way to describe something that is innovative or cutting edge. It tends to imply an even greater advancement of technology that is almost so clever that it is unbelievable in its current state.

    Instead of: “The new technology we have purchased is bleeding edge.”

    Try saying: “The new technology we have purchased is innovative.”

    Tiger team

    A tiger team is a group of experts brought together for a single project or event. They’re often assembled to assure management that everything is under control, and the term suggests strength.

    Instead of: “The tiger team will solve the problem.” 

    Try saying: “The experts will solve the problem.” 

    Lots of moving parts

    When a project is complicated, this phrase is sometimes used to indicate lots is going on.

    Instead of: “This project will run for several months and there are lots of moving parts to it.”

    Try saying: “This project will run for several months and it will be complicated.”

    A paradigm shift

    Technically, this is a valid way to describe changing how you do something and the model you use. The word “paradigm” (pronounced “para-dime”) is an accepted way or pattern of doing something. So the “shift” part means that a possible new way has been discovered. Second-language English speakers however, might not be familiar with the meaning and might be confused about what it actually means.

    Instead of: “To solve this problem, we need a paradigm shift.”

    Try saying: To solve this problem; we need to think differently.”
