Assalamualaikum warahmatullahi
0:03
wabarakatuh On this occasion
0:05
I will explain the material related
0:07
to the 9th grade Informatics lesson
0:11
still in chapter 1 This material is contained on
0:14
pages number 5 to number
0:17
8 which are in class 9 just go ahead
0:26
the material well first of all this is a
0:30
continuation of the previous video Inah ee
0:32
second video for learning in class
0:36
9 what is learned in the
0:39
subject of Informatics SMP well this is
0:42
the continuation namely C through this chapter
0:45
you learn to connect the experience of
0:47
learning informatics in the past to be
0:50
knitted with what will be learned
0:53
1u years ahead this chapter is a
0:56
road map of learning Informatics for
0:58
SMP students Do you remember the
1:01
Informatics building Well so we can
1:04
conclude for this first CHAPTER is a
1:08
students who are in class 9
1:12
Informatics in the future well Let's
1:15
see this is the building of the pillars of
1:18
informatics on the roof there is a
1:21
cross-field practice tik there is SK JKI ad ap
1:24
dsi computational thinking Well does anyone
1:28
know the abbreviation of these words Let
1:30
's look beside it tik that means
1:33
information and communication technology
1:35
next there is sk sk that is a
1:39
computer system JKI computer and
1:42
internet network Aad data analysis ap algorithm
1:45
and programming and then and then
1:48
dsi social impact Informatics those are
1:52
important abbreviations that are often
1:53
used in the future in the discussion of the
2:03
computational thinking Well, what is e
2:08
computational thinking Let's see Let's
2:11
remember in grade 7 You have
2:13
known the basics of problem solving
2:15
and the four foundations of
2:19
computational thinking through examples of
2:20
everyday life, namely
2:23
decomposition, abstraction, algorithms, and
2:27
pattern recognition, you learned to think about how
2:30
algorithms are executed so that they
2:33
get results that are in accordance with
2:35
the sequence of instructions and applicable conditions, the
2:39
done include the following,
2:41
namely one is looking for the
2:44
most optimal solution to a problem,
2:47
for example through the case of the shortest time
2:50
needed to fill water into a
2:52
bucket, the second is getting to know the
2:54
link kit list data structure through
2:58
the game of arranging letters, the third is
2:59
modeling simple problems so that
3:02
problem solving runs efficiently
3:05
modeling problems that have
3:08
bolean or binary properties and logical operations
3:12
Or so computational thinking Sin we
3:17
remember the ee material that
3:19
we have learned in grade 7 because there is a
3:21
connection that we will learn in
3:24
grade 9 when So try to remember the
3:27
basic material that has been studied
3:29
previously while sitting in the
3:35
next this is the continuation of the previous
3:38
computational thinking is still about
3:40
computational thinking Let's remember while the
3:42
previous one let's remember in the 7th grade
3:45
now let's remember in the 8th grade you
3:48
have studied the concept of input process
3:51
output functions and executing
3:54
a series of steps consisting of
3:56
several calls to the same function
3:58
you are asked to determine the
4:01
right steps to produce
4:03
an output that has been determined by
4:05
the algorithm You also learned several
4:08
data representations, namely sets and
4:11
number systems Binary octal and decimal
4:16
involving sets that require
4:18
logical reasoning You have known
4:21
and used the stack data structure to
4:23
change infix expressions to positive Do
4:26
you realize that with
4:28
these provisions you will be familiar with
4:31
any number system and expressions
4:33
in any form well Let's
4:37
remember the material in the
4:40
8th grade because in the 8th grade you
4:43
have studied related to input
4:46
process and output so in the 9th grade
4:49
there is another connection related to the material
4:54
What's next Well after
4:56
we remember back from the 7th grade
4:58
to the 9th grade Well what is next
5:01
that we will learn in the 9th grade in the
5:03
9th grade you will practice
5:05
solving problems that involve
5:08
more complex data structures, namely graphs
5:10
and trees or Tri data structure
5:14
is a structure that is the
5:15
basis of data representation for chapter 1
5:19
related to Informatics
5:21
SMP 7 modeling various
5:25
daily problems you will solve
5:27
pattern recognition problems based on
5:32
oror You will also learn algorithms
5:35
in unflack, namely designing
5:38
robot steps through this problem you will
5:41
implement the concept of repetition
5:43
efficiently because it needs repetition the
5:46
plan where the robot steps too
5:50
composed to bring up the
5:52
parts of the plan that are repeated well in
5:56
ee here you will practice namely
6:00
solving How is it related
6:01
to more complex data structures
6:04
related to trees or Tri
6:15
communication technology the second if the first one was
6:19
computational thinking Well the
6:24
second is technology ee
6:27
information and communication technology Let's remember
6:30
in grade 7 Well let's remember again in
6:33
grade 7 approximately what we have
6:35
learned in grade 7 because it is related
6:37
to grade 9 you learn ICT
6:44
used to help complete
6:49
learn to operate applications You
6:54
problems and support assignments Well so
6:59
ee before discussing related to
7:02
because in chapter 3 in grade 9 there is also
7:06
learning related to ICT so it is
7:09
related to information or
7:11
The knowledge that you have gained in grade
7:13
7 will be related to grade 9 and in
7:17
grade 9 we will also discuss the
7:23
daily work later what are the
7:31
because it is hoped that after e
7:34
experienced can use the application
7:37
and also after that can also
7:39
reflect the concept so that it can be
7:44
other applications or
7:45
similar that's the goal Ah Let's remember
7:50
again approximately in class
7:53
if earlier Let's look at earlier in grade
7:54
7 now in class Del in class Del
7:59
approximately what we have
8:03
you not only use one application
8:05
you have learned to use several
8:07
tools or tools at once to
8:10
produce integrated content
8:12
Well so in this class you have also
8:15
remembered again Eh have
8:18
used one application and using in
8:22
one application there are also how many tools
8:26
or equipment at once to
8:28
produce integrated content ee
8:30
later in grade 9 there is also a connection
8:35
ee next this is a continuation of earlier
8:41
EE colleagues or teachers
8:45
or students can read again
8:52
this information and communication technology because we remember again
8:57
we have learned well eh next after
9:01
eh tick earlier what we learned in
9:04
9th grade Well in 9th grade you are invited
9:06
to analyze various contents in
9:11
everyday environment then determine the
9:14
most appropriate tools to produce
9:15
a computational artifact by
9:17
using word processing applications,
9:19
spreadsheet processors,
9:22
presentation processors and document processing applications
9:24
Well, in more depth, more specifically, the
9:27
material is studied in 9th grade because
9:30
this material is the same as in 1st grade there is
9:32
ICT, 2nd grade there is ICT, 3rd grade also has
9:35
that topic but the material is more
9:37
in depth, more specifically
9:40
related to ICT because here
9:43
the participants will be invited to
9:45
analyze various kinds of content
9:53
document creation, maybe for later we will
9:57
learn related to using
9:58
applications, ah, what words are
10:01
contained in word processing applications,
10:03
worksheets, how to process
10:05
presentations and document processing applications
10:07
Well here we will learn
10:09
everything in 9th grade more in depth and in
10:19
e Okay Ladies and gentlemen,
10:22
that's all I can say,
10:25
hopefully it's useful ee I end,
