Increased Interest in Radiation and Radioactivity

The Hokkaido University Faculty of Engineering
began developing OER to help teach the basics ofradiation and radioactivity - B roa dcasted on
Hokkaido University OpenCourseWare (OCW).

The course "Effects of Radiation" was released on edX(i m p ro v e m e n t s i n c l u d e: t h e a p p l i c a tion o f
instructional design, the addition of supplementary
content as needed, etc.)

Students would prepare using the OER produced forthe edX course before class. Using the online learning
platform ACE, students could watch both the videos
made as OER and previous lectures. In class, students
used'PBL'to think through issues.

General education

Using Shin Godzilla

Because the class was offered to students from boththe humanities and the sciences, there was no
guarantee that all participants would have even abasic grasp of Physics.

Motivation

It was necessary to help students acquire thenecessary basic knowledge while still increasing theirmotivation to participate in the class.

Afte 『 Fukushima

It was necessary to think about how to create acourse on radioactivity and radiation that could
appeal to students after the disaster that had
occurred in Fukushima.

---------------------------Cou『se Developmentthrough P『acticeUsing the movie Shin Godzilla as the course theme as an
example that depicts how modern Japanese society
would respond when faced with a monster (Kaiju, 怪獣）
that emits radiation.

G 編i醤Instead of merely trivializing complex problems from thereal world, instructors are able to create cla s s
assignments using a fictional object.This helps theinstructors adjust the level of difficulty of theseassignments, which in turn makes it possible to create
problems for students who are not used to making
calculations in physics.

Inst『ucto『The theme of Shin Godzilla was provided to help
course inst 『uctors utilize OER and effectively
develop a class on radiation. He 『e, you can see an`―-------------------------'example of how this theme helped students learn

about 『adiation and 『adioactivity.

PBLExampleA

Out o f the fo l l o w ing
options, which would be
the one which offe 『s the lowest
exposu『e to Godzilla's 『adiation?
Assume that Godzilla is 1 km
away and has a radiation dose『ate of 1 mSv/h.

j\ Tamotsuf(...

1 Evacuate below ground:

Distance of 0.1 km; 1 meter thick concrete barrier
between you and Godzilla.
1 mSv/h + (0.1) 2 箕 (4.14 算 10-8)=

こ：-------------｀＿-====こ＿ ―-山4.14 算 10 - 6 mSv/h = 0.004µSv/h

2 Just『un away!:
Distance of 2 km.

1 mSv/h + 2 = 0.25 mSv/h
2---- --------------

3 Hide inside of a car:Distance of 1 km; steel plate barrier between youand Godzilla

Kozaki

1 mSv/h 箕 (0.74)= 0.74 mSv/h

OER Use and Improvement●The use of Godzilla in this course has also helped make the classappealing to students and has led to high course evaluations.

• By using a fictional work as course material, students were able
to better learn how to use the scientific knowledge they had
already acquired to form hypotheses.
●竺Improvements are continuously being made to the course based on student feedback
concerning the course and the educational materials used.

Improvements include re-editing preparatory educational resources, changes to course content from theinstructors, and changes to how group-work is conducted.

Next Steps

Students evaluated one another based on whether
their pee 『s had correctly utilized their knowledge ofradiation and radioactivity.

• We are aiming to achieve a cycle in which continually'la ■•■ i 曇 11

more feedback for further improvements.

• We will be aiming to offer a MOOC on the subject ofradiation and radioactivity domestically in Japan inthe future as well.

These activities have been performed in part within the Japanese Ministryof Education, Culture, Sports, Science and Technology's project; Nuclear
Power Training and Education Support Program (Nuclear Education
and Research ln1t1ative). We would like to express our gratitude for thesupport we have received from them here.
