Trials for computer science education at elementary schools in Japan
Informatikos mokymo tyrimai Japonijos pradinėse
mokyklose

Do you know
Computer Science Unplugged,
(CS Unplugged)?
CS Unplugged is
• Originally proposed by prof. Tim Bell in NZ
• A method for children easy to understand computer science WITHOUT COMPUTER (= Unplugged)
• http://csunplugged.org/
Anyway
Please experience CS Unplugged first!
Today’s Activity is
Magic Trick!
• I am going to show you a magic!
• Please find how trick is done!
• However you find the trick, please do not tell the people around.
1. Lay out the cards in a 5 × 5 square, with a random mixture of sides showing
2. Add another row and column, just to make it a bit harder
3. Please flip over ONE CARD ONLY while I cover my eyes
4. I shall identify the changed card.
Can you find how trick is done?
Who found the trick?
Shall I play it again?
Let’s try in some group!
Make some groups who is included the
at least person who knows the trick
It’s informatics!
Letter “C“?
Letter “C” in computer graphics
Letter “O” in computer graphics
During transmission
NOISE
0 1 ↓↓
→”bit”
3 bits
2 1
2 3
0 5 2 4 0
In this case
Added a line and a column to be even numbers of bits
“Parity” bits (“paritetas bitai”)
0 6 2 4 0 4
4 2 2
2 4 2
0 6 2 5 0 4
4 2 3
2 4 2
Real life examples?

Last digit called “check digit”
like parity bits
CS Unplugged Activities in Japan
• “Fujitsu Kids Event”
– held by Fujitsu Ltd
– with The Japanese Committee for the International Olympiad in Informatics
– since 2008
– for 4th – 6th grade primary school children
– 90 children (30 children x 3 times) were recruited on Fujitsu Web
However
• There are quite few CSU at primary school class!
• I would like to do the computer science learning at primary schools
• To introduce children Computer Science
• How?
School Education System in Japan
• The kind of School – Primary : 6 - 11 years old
– Secondary : 12 – 14 years old
– High : 15 – 17 years old
• School subjects (at Primary School) – Japanese, Arithmetic, Science, Social studies,
Music, Drawing and crafts, Home economics, Physical Education, Health education, Moral education, Calligraphy, Special Activities, Period for Integrated studies
the course of study
• All teachers must educate under the course of study
• Revised every 10 years
• The latest revision is 2008 and 2009
– Fully started in 2012 at primary and secondary school, and in 2013 at high school
History of Information Education in Japan (in 1980s)
1983 1985 1989
OECD reported that PCs in classroom in Japan was lowest among the developed countries
MEXT Budget for buying PC at school (limited)
Primary
Secondary “Information Basics”(elective) in the subject “Technical home economics”
High
In 1990s 1997 1999
GOV Millennium project ・Internet connection by 2001 (fy) for all schools ・All teacher can use computers ・PC in all classroom by 2005 (fy)
MEXT Target for Information Study ・Practical Skill of Information Utilization ・Scientific Understanding of Informatics ・Attitude to Participate in Information Oriented Society
Primary Information Study (One of the regions of Period for integrated study, elective)
Secondary “Information Basics”(required) in the subject “Technical home economics”
High New Subject “ Information Study”
In 2000s 2008 2009
MEXT Revised course of study for primary and secondary school, stated that Information education should be done in the existing subjects
“Guidance on the informatization of education“ was published
Revised course of study for primary and secondary school
"Guidance on the informatization of education" by MEXT of 2010
School Practical Skill of Information Utilization
Scientific Understanding of Informatics
Attitude to Participate in Information Oriented Society
Primary
28 teaching examples in 5 pages
NO teaching examples in 0.5 pages
8 teaching examples in 2 pages
Junior High
23 examples in 3.5 pages
7 examples in 2 pages
20 examples in 3.5 pages
High 23 examples in 4 pages
11 examples in 2 pages
18 examples in 3 pages
So
• I would like to do the computer science learning at primary schools
• To introduce children Computer Science WITH FUN!
• How?
Why NOT CS in Primary school
1. There is no clear description for Computer Science in the course of study
– Even if teacher wants to teach CS, he/she think there is no legal basis
2. Can teacher teach CS?
– Most of the primary school teachers think they are NOT good ad CS
– Teacher will not teach CS if he/she think it is not effective for children
Solution for 1
• I have checked the textbook (all subjects) of the elementary school
• Matching percentage of school activities and CSU activities
• 57-100% (average 80%) of CSU activities was done in primary school one
Solutions for 2 (My latest task)
2. Can teacher teach CS?
– Most of the primary school teachers think they are NOT good ad CS
If I could show the examples of the CS study, they could do (TEACHERS ARE PROFESSIONALS TO TEACH)
– Teacher will not teach CS if he/she think it is not effective for children
If we could show that CS study is effective, they would do
