Dodger how was ill and hanging hi everyone my name is hanging Liang i am
everyone my name is hanging Liang i am
everyone my name is hanging Liang i am professor in computer science and today
professor in computer science and today
professor in computer science and today i’m going to talk about something I’m
i’m going to talk about something I’m
i’m going to talk about something I’m very passionate about today I’m going to
very passionate about today I’m going to
very passionate about today I’m going to talk about why today in this society you
talk about why today in this society you
talk about why today in this society you want to explore with technology what it
want to explore with technology what it
want to explore with technology what it means to explore with technology and how
means to explore with technology and how
means to explore with technology and how you can explore technology so let me
you can explore technology so let me
you can explore technology so let me first begin with this question so why
first begin with this question so why
first begin with this question so why exploring with technology in today’s age
exploring with technology in today’s age
exploring with technology in today’s age as you know technology is very pervasive
as you know technology is very pervasive
as you know technology is very pervasive everywhere you can see technology just
everywhere you can see technology just
everywhere you can see technology just look at yourself who doesn’t have a
look at yourself who doesn’t have a
look at yourself who doesn’t have a moral device in his or her hands in this
moral device in his or her hands in this
moral device in his or her hands in this room most of you would have one right
room most of you would have one right
room most of you would have one right technology has changed the past
technology has changed the past
technology has changed the past dramatically and it will change the
dramatically and it will change the
dramatically and it will change the future in a very very significant way
future in a very very significant way
future in a very very significant way most likely you you you are listening to
most likely you you you are listening to
most likely you you you are listening to the talk about the astronomy you know
the talk about the astronomy you know
the talk about the astronomy you know the professor from astronomy without
the professor from astronomy without
the professor from astronomy without technology it would be very difficult to
technology it would be very difficult to
technology it would be very difficult to explore astronomy in this way so now
explore astronomy in this way so now
explore astronomy in this way so now having said this how then we can explore
having said this how then we can explore
having said this how then we can explore with technology my answer is actually
with technology my answer is actually
with technology my answer is actually quite straightforward and quite simple
quite straightforward and quite simple
quite straightforward and quite simple so let’s say you want to study English
so let’s say you want to study English
so let’s say you want to study English culture with English English speaking
culture with English English speaking
culture with English English speaking people so the only way to do this is if
people so the only way to do this is if
people so the only way to do this is if you learn English so the same thing
you learn English so the same thing
you learn English so the same thing applies to technology if you want to
applies to technology if you want to
applies to technology if you want to explore with technology you have to know
explore with technology you have to know
explore with technology you have to know how to communicate with technology or at
how to communicate with technology or at
how to communicate with technology or at the very least know the process through
the very least know the process through
the very least know the process through which you can communicate with
which you can communicate with
which you can communicate with technology right so then the demyx what
technology right so then the demyx what
technology right so then the demyx what is further a little bit let me let me
is further a little bit let me let me
is further a little bit let me let me borrow this quote from Steve Steve
borrow this quote from Steve Steve
borrow this quote from Steve Steve before he died he said this everyone
before he died he said this everyone
before he died he said this everyone that means including you actually should
that means including you actually should
that means including you actually should learn how to program so why he said this
learn how to program so why he said this
learn how to program so why he said this so when I first read the first part
so when I first read the first part
so when I first read the first part thinking why this is the case and so if
thinking why this is the case and so if
thinking why this is the case and so if you read further he says because it
you read further he says because it
you read further he says because it teaches you how to think I said wow
teaches you how to think I said wow
teaches you how to think I said wow that’s quite interesting because I
that’s quite interesting because I
that’s quite interesting because I thought I knew how to think right so why
thought I knew how to think right so why
thought I knew how to think right so why is no Steve saying this that we should
is no Steve saying this that we should
is no Steve saying this that we should learn how to program in order to think
learn how to program in order to think
learn how to program in order to think so what is the relationship between how
so what is the relationship between how
so what is the relationship between how to program and how to think if Stevie
to program and how to think if Stevie
to program and how to think if Stevie saying this he must have something in
saying this he must have something in
saying this he must have something in mind I taught myself so explore this
mind I taught myself so explore this
mind I taught myself so explore this further so what is the relationship
further so what is the relationship
further so what is the relationship between this and the relationship within
between this and the relationship within
between this and the relationship within these to a large extent I think is what
these to a large extent I think is what
these to a large extent I think is what is called computational thinking
is called computational thinking
is called computational thinking computational thinking is a set of
computational thinking is a set of
computational thinking is a set of approaches that you can use so most of
approaches that you can use so most of
approaches that you can use so most of you have done as a rate writing right so
you have done as a rate writing right so
you have done as a rate writing right so to do essay writing you need critical
to do essay writing you need critical
to do essay writing you need critical thinking computational thinking is
thinking computational thinking is
thinking computational thinking is similar but in the context of Technology
similar but in the context of Technology
similar but in the context of Technology you apply computational thinking to
you apply computational thinking to
you apply computational thinking to solve problems what I mean by this let
solve problems what I mean by this let
solve problems what I mean by this let me explore this further with you so
me explore this further with you so
me explore this further with you so computational thinking is closely
computational thinking is closely
computational thinking is closely related to Poland solving it’s a set of
related to Poland solving it’s a set of
related to Poland solving it’s a set of skills and approaches that you can take
skills and approaches that you can take
skills and approaches that you can take to look at a problem and try to find
to look at a problem and try to find
to look at a problem and try to find solutions to that particular problem as
solutions to that particular problem as
solutions to that particular problem as a computational thinker you will need to
a computational thinker you will need to
a computational thinker you will need to have a few things you need to know how
have a few things you need to know how
have a few things you need to know how to recognize patterns how to decompose
to recognize patterns how to decompose
to recognize patterns how to decompose things into smaller chunks how to do
things into smaller chunks how to do
things into smaller chunks how to do things a step by step how to do Roy
things a step by step how to do Roy
things a step by step how to do Roy logical reasoning and more importantly
logical reasoning and more importantly
logical reasoning and more importantly how to analyze problems are different
how to analyze problems are different
how to analyze problems are different levels at the macro level and also at
levels at the macro level and also at
levels at the macro level and also at the micro level so let me let me look at
the micro level so let me let me look at
the micro level so let me let me look at this one of these in more detail so the
this one of these in more detail so the
this one of these in more detail so the composition the idea of the composition
composition the idea of the composition
composition the idea of the composition is very important because right now we
is very important because right now we
is very important because right now we are facing problems that are bigger and
are facing problems that are bigger and
are facing problems that are bigger and bigger and bigger so if you are able to
bigger and bigger so if you are able to
bigger and bigger so if you are able to break the problem down into smaller
break the problem down into smaller
break the problem down into smaller chunks you should and you will be able
chunks you should and you will be able
chunks you should and you will be able to understand the problem and solve the
to understand the problem and solve the
to understand the problem and solve the problem in a better way so the other
problem in a better way so the other
problem in a better way so the other aspect computational thinking is that it
aspect computational thinking is that it
aspect computational thinking is that it forces you to have a clear way of
forces you to have a clear way of
forces you to have a clear way of England

England ending your solution many times we have
ending your solution many times we have
ending your solution many times we have a solution to a particular problem but
a solution to a particular problem but

sometimes we don’t know how to implement
sometimes we don’t know how to implement or make operational the steps that you
or make operational the steps that you
or make operational the steps that you need to do so with computational
need to do so with computational
need to do so with computational thinking you will have to have a

specific set of steps that you want to
specific set of steps that you want to follow to solve that particular problem
so let’s look at the code again this is
