批判的思考と評価に関連する一般的な神話がいくつかあります。多くの人は、特に言語が限られているクラスでは、批判的思考を評価することは不可能だと考えています。しかし、それは可能です!ここで成功の鍵となるのは、言語スキルと認知スキルを分離できるタスクとルーブリックを作成することです。結局のところ、言語レベルが低いからといって、必ずしも生徒の批判的思考能力を反映しているわけではありません。

では、生徒が何を知っているかだけでなく、 どのように知っているか を測定するにはどうすればよいでしょうか。

批判的思考を測定する方法

まず、公式評価と非公式評価の2種類の評価を検討する必要があります。正式な評価は、タスク、レッスン、またはスキル構築活動の終了時に行われる傾向があり、通常は生徒が作成した作業に焦点を当てます。その後、非公式の評価を行います。これらは、その場でのやり取りを含む評価です。これらのタイプの評価は、批判的思考を測定する上で重要な役割を果たします。

正式な評価

評価は、生徒が生み出す最終的な作品にのみ焦点を当てるべきであるという誤解がよくあります。最終的な「製品」は紛れもなく重要であり、多くの場合、言語能力の理想的な尺度です。しかし、最終的な作品を作成するプロセスでは、生徒の批判的思考スキルが実際に発揮されているのを見ることができます。

言語的思考と批判的思考の両方を測定するルーブリックを設計する際には、言語的思考と批判的思考のどちらか一方だけに焦点を絞るようにしましょう。これらの異なるスキルを念頭に置くことで、言語スキルと批判的思考スキルを区別し、正式な評価に関してはそれらを別々に評価することができます。

言語スキルを測定するときは、ブルームの初期または基本的な認知領域をモデルとして使用します。

これらの項目を測定すると、実際には言語スキルを測定していることになります。たとえば、読書活動では、次のような質問をすることがあります。

  • 誰についての話ですか?
  • 物語の舞台はどこで?
  • ストーリーの主なアイデアは何ですか?

彼らは全体的な組織と主要な語彙を理解できますか?これらのタイプの質問は、学生の言語能力を評価します。

そして、批判的思考に関しては、ブルームの認知領域のより高度なレベルが有用なガイドを提供します。

これらのタイプの質問は、学生のメタ認知または批判的思考を評価します。

  • ストーリーにとって最も重要なキャラクターは誰ですか?
  • なぜでしょうか。
  • キャラクターの行動に同意しますか、それとも同意しませんか?
  • なぜですか、なぜそうでないのですか?

評価における言語と批判的思考の明確な分離は、各学生の両方のスキルの進歩を測定するのに役立ちます。

非公式の評価

これらの非公式の評価はどうですか?その場での評価では、批判的思考と言語スキルを明確に描写するのが難しい場合があります。

たとえば、グループワークを割り当てている場合は、学生同士のやり取りのチェックリストを保管することを検討してください。チェックリストの項目には、次のようなものがあります。

  • 誰が推論したのか?
  • 他の学生のアイデアの理由を提供したのは誰ですか?
  • 誰が比較したのか?
  • 誰が結論を出したのか?

また、生徒にチェックリストを保管してもらい、これらの質問を電子掲示板に投稿するように依頼することもできます。自己評価と同様に、これらのピアツーピア評価は、生徒に反省と気づきを促すことができます。

ルーブリックは、非公式の評価にも役立ちます。例えば、学生にエッセイの準備や執筆を依頼したとします。批判的思考を測定するために、各学生がエッセイに取り組んでいるときのアイデア出しプロセスを見ることができます。

  • 学生は考えられるすべてのトピックを見ていますか?
  • 学生が選択したオプションを選択する要因は何ですか?
  • 彼らは他のアイデアを認識していますか?

これらの質問に対する答えは、生徒が批判的に考えているかどうかを教えてくれます。

他のスキルと同様に、批判的思考の評価は公式にも非公式にも行う必要があります。プロセスと最終製品の両方を考慮する必要があります。そして、その際、言語スキルとメタ認知を区別するルーブリックを慎重に設計する必要があります。

    How to encourage your teenage students to become independent learners
    投稿者 Nicola Pope
    所要時間: 5 minutes

    Learning is a lifelong activity regardless of age, position or ambition. Many teachers embody this philosophy themselves, and would like nothing more than for their teenage students to develop strategies to become independent learners. But teachers often feel frustrated when their students rely on them too much or show a lack of motivation and focus in the classroom.

    Let’s look at how to start a project that holds your students’ attention. We’ll also go into how you can help your students practise and develop a range of English language skills at the same time.

    The benefits of starting a project that interests your students

    Group projects are motivating because they give students a common objective to work towards. The need to work as part of a team teaches teens collaboration skills such as accountability. When learners decide on roles within their groups it soon becomes apparent just how important it is for them to be responsible and do their part.

    Project work also often encourages students to push themselves beyond their comfort zones as they try and test new skills. This is often true when learners are required to present on a topic or learn how to do something practical (like using PowerPoint or Google Slides for presentation design).

    In addition, projects can test a variety of English language and 21st-century skills such as:

    • Critical thinking skills (for planning and development of ideas)
    • Topic/subject-specific vocabulary
    • Reading and listening comprehension (for researching)
    • Speaking skills (for group work)
    • Creative skills (for project development and production)
    • Presenting skills (for the final delivery of the project)

    Furthermore, when projects take place over several classes, students often eventually get into a routine and seek less direction from the teacher. They know what needs to be done and get on with it in their groups. Of course, you will still need to monitor and offer guidance throughout the project.

    The key elements of an independent learning project

    Find a meaningful subject matter

    First, you’ll need to start with a topic that engages your students. To discover this, put students in groups (online in breakout rooms or in the classroom) and have them work together and mind map some local, national or global problems they would like to solve.

    For example:

    • The local theater has closed down and they want to set up a new drama club.
    • There is a lot of pollution in the capital city and they want to help reduce it.
    • The rainforest is being deforested and they want to create awareness.

    After they have a good-sized list, instruct each group to pick something they would like to learn more about. Alternatively, if your students are unlikely to find interesting problems to solve themselves, provide them with several short, level-appropriate reading materials about topics you think will catch their attention. That way they can learn about local or international issues and choose a project focus.

    Balancing guidance and instruction

    A vital goal of this project-based approach is to encourage students to be independent. That does not mean they should have no boundaries or objectives, however.

    You’ll need to set deadlines, tell them what you expect of them and explain how they should present their projects at the end. And depending on their levels, your students will also need a certain amount of scaffolding. You can do this using a set of questions. For example:

    1. What is the main problem you want to solve?
    2. Who does it affect?
    3. Why is it important to change?
    4. What steps could you take to solve the issue?
    5. Who could help you do this?
    6. How could we do this as a group?
    7. How can we present the issue to make people care about it?

    These questions can form the basis of the project, which can last from one to several weeks, depending on their age, level and time constraints. Adapt the questions to suit your students and the specific needs of their projects.

    Facilitating teamwork

    Encourage students to work together to plan, research and present their ideas. Set days or classes by which certain project elements must be completed. This helps ensure that the students make progress and encourages them to ask you questions if they are stuck.

    Decide whether you want to give set times during your classes to work on the project, or whether you want to dedicate entire classes to their work. Also, think about how much work should be completed in your student's own time. Their workload, level of English and access to technology will all impact your decision.

    For example:

    • Class one: Define the problem you want to solve. Consider what you need to find out, decide on individual roles and develop an action plan. Show the teacher your progress.
    • Class two: Research your project questions and share what you find with the group. Is there anything else you need to know? Show the teacher your progress.
    • Class three: Come up with a presentation outline and begin to work on it.
    • Homework: Each work on your individual presentation section.
    • Class four: Show the teacher your progress. Practise your presentations.
    • Class five: Practise and then deliver your presentations.

    You may wish to allow students the freedom to choose how they would like to present it. Give instructions on how long you expect the presentation to be. If working remotely, collaboration tools such as Google Docs, Padlet and Trello are excellent for facilitating teamwork.

    Here are some ways you might ask them to present:

    • A poster and presentation
    • An online presentation (e.g. using PowerPoint)
    • A website (on paper or online)
    • A video presentation
    • A theatrical production
    • A podcast episode

    Keep in mind that the objective is to help them research, present and deliver a project in English. Check in regularly on progress and provide feedback and help whenever needed.

    While it’s important to monitor and guide them in English as they work, it’s also crucial to let students make their own decisions.

    Do English test results ever show the full picture?
    投稿者 Alice Bazzi
    所要時間: 3 minutes

    For admissions teams, English test results are more than just a number. They are a key indicator of whether a student is ready to succeed in an academic environment. But a common concern remains: can a test truly reflect a candidate's full language ability?

    The answer lies in how the assessment is designed.  

    PTE Express moves beyond traditional testing approaches by focusing on integrated, real-world language skills. Instead of evaluating skills in isolation, it measures how candidates use multiple skills together, reflecting the way English is applied in university settings.

    For example, test candidates may be required to listen to information and respond in writing, or read content and communicate their understanding verbally. These tasks reflect real academic activities, such as attending lectures, participating in discussions and completing written assignments.

    Halloween idioms and expressions in English
    投稿者 Charlotte Guest
    所要時間: 3 minutes

    Halloween is a great time to watch scary movies, tell ghost stories and learn new English expressions. But did you know that many English phrases are connected to fear, ghosts and the supernatural?

    Some of these expressions are used all year, not just at Halloween. Learning them can help you understand conversations, books, movies and everyday English.

    Here are some Halloween-related idioms and expressions, with simple meanings and examples to help you use them.

    1. Scared to death

    This expression means being extremely frightened. It does not mean that someone actually dies. 

    Example: The sudden noise scared me to death.

    You can use this phrase when something gives you a big fright, such as a scary movie or an unexpected noise.

    2. Give someone the creeps

    If something gives you the creeps, it makes you feel uncomfortable or afraid. 

    Example: That old doll gives me the creeps.

    You might use this expression to describe an unusual place or something that makes you feel uneasy.

    3. Make your blood run cold

    This expression describes something that makes you feel very frightened. 

    Example: The story about the haunted house made my blood run cold.

    It is often used when talking about frightening news, stories or experiences.

    4. A ghost town

    A ghost town is a place where very few people live or go. It can also describe a place that is unusually empty. 

    Example: The shopping mall was a ghost town on Sunday morning.

    Although this phrase sounds like it belongs in a scary story, people use it in everyday conversations.

    5. Come back to haunt you

    This expression means that something from your past causes problems for you later.

    Example: If you do not study for your exam, your decision could come back to haunt you.

    The phrase is often used when talking about mistakes, poor decisions or things people wish they had done differently.

    6. Skeletons in the closet

    This idiom means having secrets that someone does not want other people to discover.

    Example: The politician was worried that reporters would find the skeletons in his closet.

    The phrase is connected to Halloween imagery, but it is often used when discussing personal secrets or hidden problems.

    7. Like a bat out of hell

    This expression describes someone or something moving extremely fast. 

    Example: When the teacher said the lesson was over, the students ran out like bats out of hell.

    It is an informal phrase, so it is best used in casual conversations rather than formal writing.

    8. Witching hour

    The witching hour traditionally refers to a late-night time when supernatural events are believed to happen.

    Today, people may also use it humorously to describe a time when strange things happen or when someone becomes unusually active or difficult to manage. 

    Example: The baby always wakes up around midnight, so we call it the witching hour.

    The exact time associated with this expression can vary depending on the story or tradition.

    9. Dead tired

    If you are dead tired, you are extremely tired. The word dead adds emphasis to the expression. 

    Example: I was dead tired after working all day.

    This is a useful everyday expression, especially when talking to friends or family.

    You don't need to wait until Halloween to use them. Many of these idioms are common in everyday English, so practise them throughout the year to build your vocabulary and feel more confident when speaking.
