Hello and welcome to my short lecture today on an introduction to critical thinking at university.

So just to begin, I think I should say

that critical thinking is a huge area and to cover all elements will take a significant amount of time,

so I'm just going to look at the basic key aspects associated with reading and writing at university.

Now I've divided my lecture today into five key parts.

I'll begin by defining critical thinking, then I'll use recent research to discuss alternative thinking styles.

I'll then use Bloom's Taxonomy to highlight higher order thinking skills,

which leads into a simple approach to help activate your critical thinking.

And finally, I'll demonstrate critical thinking questioning on this lecture.

OK, so let's begin with a definition.

Thank you.

Critical thinking is a systematic evaluation of the arguments, ideas and theories of others.

The basic premise of critical thinking involves asking critical questions to form an educated opinion of whether

or not those resources are credible.

On a basic level, we are questioning the things we read and hear to see if they are objective

truthful and supported by appropriate evidence.

However, one of the main challenges is

that each of us carries a set of beliefs and opinions that may interfere with our willingness to alter these beliefs,

even when faced with concrete evidence that refutes them.

Generally, everyone has an opinion about most things, but of course these opinions can be founded in unreliable and invalid information.

OK, so moving on to my second point, which is alternative thinking styles.

I'm going to refer to the research by Brown

and Keely 2013 as in my opinion their analogy provides a clear explanation of thinking types.

So, according to them, there are two distinct thinking styles: the sponge and panning for gold.

So, the sponge involves the basic premise of passively absorbing information without the use of critical thinking.

The two benefits of this style are

that the person can absorb large amounts of information to view the world from different perspectives

and it does not require huge amounts of mental exertion.

However, this process of thinking offers no dependable procedure for determining which opinions or information to trust and which ones to reject.

The second approach which is referred to as panning for gold

uses the river mining metaphor of separating particles of gold from soil by washing in a pan with water.

It highlights that critical thinking is carefully inspecting and examining the information you read.

This process is beneficial as it asks active readers

and listeners to frequently ask critical questions and take time to contemplate whether the information is reliable and factual.

Obviously, this type of thinking is challenging and often repetitive,

but failure to do this will lead to a passive acceptance of ideas without critical analysis.

Okay, this leads nicely into Bloom's taxonomy.

This is a classification pyramid of learning levels which maps the way we think and process information.

The lower levels of learning are remembering, understanding and applying.

These can be seen as the sponge or lower order thinking skills, where information is given and absorbed.

The higher order thinking skills are analysing, evaluating and creating.

These are planning for gold or your critical thinking skills.

So let's focus on the higher order thinking skills starting with analysing.

So, analysing is breaking the information down into separate components and looking for relationships between ideas and overall structures.

Through analysing content, you will recognise unstated assumptions, logical reasoning and relevancy of data.

So, at this level, you can answer questions like why, how and what if.

Moving on to Evaluating.

Evaluating is judging, assessing and criticising information through using what you know to make a decision and support your views.

To be successful at this, you need a profound understanding of the topic or idea you are evaluating.

At this level you can answer questions like "So what?" and "What's next?"

Creating is the highest level where you combine all elements of the taxonomy to produce new or original work.

It requires inventiveness and originality to form new opinions and structures.

At this level you can answer questions like: How can it be improved or how can it be changed or adapted?

Now, there are many critical thinking question sheets and resources on the internet

and in your universities that are all very beneficial and helpful.

But, I find it more productive to focus on analysing

and evaluating rather than going through a whole list of questions

every time I find a point in a text I want to question.

So, my advice is this: when starting out with critical thinking, just use the simple question tools of analysing which are why,

how and what if.

and evaluating which are 'so what' and 'what's next'.

This keeps your critical thinking strategies simple, focused and effective.

And more importantly, Analysis and evaluation are key components of university assessment criteria.

However, it is important to remember that critical thinking is a higher level skill and needs time to develop and mature.

It is not something you will become good at overnight as it can take months

or even years of practice to fully develop this skill.

In fact, recent research by Stanford University 2018 states that critical thinking is a lifelong process.

Okay.

So now I'm going to demonstrate how you may apply the critical thinking questioning of analysing and evaluating to this lecture today.

So let's start with analysing and the why questions.

The kind of questions you may ask could be, why did he do this lecture?

Why did he choose the Brown and Keely research and Bloom's taxonomy?

Why were only three sources used?

And then you go on to the how questions.

Possible questions are: How do we know this is reliable?

How is this similar to other critical thinking concepts?

How does this apply to me and my university study?

And then the what if questions.

Examples are: What if these concepts are wrong?

And what if it is too simplistic?

Then we move on to the evaluating questions.

And examples of so what would be Is this significant to me?

Is this convincing?

Do I agree?

What's wrong with it?

And then the what's next questions such as, will I use what I have learnt today?

How can it be improved?

And has this been disproved?

Okay, let's move on to the summary.

So today I have provided a basic definition of critical thinking.

I've used recent research to highlight the two alternative thinking styles of the sponge and panning for gold.

I focused on Bloom's taxonomy pyramid and drawn attention to the top three levels of higher thinking skills.

And in this part, I have focused on the importance of questioning words like Why,

How, What If, So What and What's Next to aid critical analysis.

The last part was to apply the higher thinking skills to today's lecture.

So, I hope today's lecture has been really beneficial in simplifying critical thinking skills for use in reading and writing at university.

My final point today is that I'd like to finish with something that was mentioned earlier.

It is to try to be consciously aware of our own beliefs and preconceived opinions, as these are the thoughts that prevent true criticality.

Thank you for listening to my lecture today.

100

Goodbye.

101

Thank you.

102

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
