PTF Connections:

Questionnaires: Thank you all for answering our questionnaires for the school in February! We are grateful to receive answers from many parents and guardians! The questionnaire results showed that many parents and guardians are satisfied with OCSI school events. We also appreciate your gratitude and comments to the school! OCSI will make the best use of your answers to school events.

IMG_20180224_115310_resized_20180312_103250869Korean Cooking Class: Mrs. Kuboyama (grade 6 mother) demonstrated Korean cooking on Saturday, February 24.  She made Korean pancakes and japchae (Korean bean noodles).  They are so yummy.  All of parents and kids enjoyed learning how to cook and to eat.  Thank you so much, Mrs. Kuboyama. We will plan another cooking class in April. Please check it out!

Reading Night: The Reading Night on March 1st was a blast with many participants! Everyone enjoyed a storybook performed by teachers, craft-making, and receiving a present of a picture book! PTF also provided drinks and popcorn for the students, and donated the gifted books. We hope this event helps our children learn to love reading. It was such a great time filled with our children’s happy smiles.

We want our students to create ideas, products, solutions

At OCSI we want all of our students to create. Sometimes people hear that word create and think that it is only for artists. Or it is only about the real standouts, like Einstein and Thomas Edison. Or it is only about the sudden “ah-ha!” moments, like the apple on Sir Newton’s head or the lightening bolt on Benjamin Franklin’s kite. Or that it’s something some people have and some don’t.

However, recent research contradicts all of these common myths. We now know that all children have a capacity to create, and that we can nurture that capacity at all levels and in all classes by cultivating curiosity, flexible thinking, imagination, persistence, discipline, collaboration, and self-evaluation.

At OCSI we want our students to create ideas, products, and solutions. And we’re excited that middle school students are doing just that:

  • 6th grade readers responded to a story by creating comics, slideshows, drawings, or inventions.
  • 7th grade geographers taught classmates about the Indian subcontinent. To do this, they created their own lessons plans and solutions to problems they came across as they prepared to teach.
  • 7th grade mathematicians created a work proposal to repaint the basketball courts at Sera-en. They used composite figures and geometry to calculate surface area for paint, and then considered labor and overhead as well.
  • 7th and 8th grade scientists used research to find an unanswered question they are interested in. Next they will create a science fair project to answer it.
  • 8th grade Bible students created a timeline of the book of Acts, visualizing events and drawing them.

In high school…

  • Computer apps students created a new website for Keystone Nazarene Church that addresses each of the needs of the client in creative ways.
  • PE students learned the basics of line dancing and then worked in groups to create their own line dance, which they performed for and taught to their classmates.
  • 10th grade readers and writers created another “book” of The Odyssey where Odysseus lands on Okinawa and the ancient Greeks meet the ancient Ryukyuan people, which is a way to connect local culture into our reading and writing.
  • Biologists created booklets to process their learning about cell structure and function.
  • Bible students created ideas connecting music and Biblical themes. They did this by listening to a series of symphonies and responding in writing and drawing to the question “What effect does music have on inspiration, reflection, joy, or sorrow?”
  • Computer scientists have been combining different sensors (light, temperature, touch) and actuators to create useful tools for automation.
  • 12th grade economists brainstormed a product to create for the market.

Students develop skills related to creating

Elementary Connections:

The ability to create new ideas and philosophies, design and revise products, and think critically to find solutions to real world problems is what makes us as humans so uniquely and wonderfully created by God. In the changing world economy, these same skills are also increasingly in demand by employers. At OCSI, we start helping children develop these skills from a very young age:

  • IMG_1002Children are working together to figure out how far to move a box from a ramp in order to have their match box cars land in the box and how to reinforce bridges on train tracks with blocks (PreK).
  • Children created their own version of the famous pigeon book series and entitled it “Don’t Let the Pigeon Be the Teacher” (1st grade writing).
  • Children created mini ecosystems/biomes in science class (3rd grade science).
  • Children designed their own inventions on paper and then made them out of 3D materials (3rd grade art).
  • Children used Little Bits technology to create a display that read the classroom temperature to help them decide when to turn on the air conditioner and are now creating and designing their own droid (5th grade science).
  • Children are writing personal memoirs after analyzing the comings and goings, major points, themes, and connections in their own lives (5th grade writing).

Little Bits Droid Creators

We’re looking forward to the OCSI Elementary Week of Reading next week! We hope that your child will have fun as we celebrate and inspire a love of reading! We hope that you will join us for Family Reading Night as well on Thursday, March 1 from 5-6 p.m.

What encourages growth?

OCSI Connections:

At OCSI, we value growth:
  • We want students to grow. We want our students to increase their understanding of God, His world, and their place in it. We want our students to enhance their skills for thinking, collaborating, communicating, and creating.
  • We want staff to grow—staff are pursuing their own professional development goals, participating in book discussions, and reading publications from over 15 professional organizations.
  • We want OCSI to grow. Our Schoolwide Action Plan targets culture, communication, key performance indicators, curriculum, and organizational stability and sustainability.
One way we encourage growth is by participating in the board-mandated ongoing improvement process (B2.4.7) that includes accreditation (B2.4.8). The focus of the process has been on 3 key steps that encourage growth: sharpening vision, assessing practice, and planning growth:
  1. Sharpening our vision helps us know what our goal is. So, staff have been reviewing OCSI’s mission, vision, and expected student outcomes; and parent newsletters have included a focus on the expected student outcomes.
  2. Assessing practice helps us see what we currently do and how effective it is. So, students, parents/guardians, and staff completed surveys. Next, high school student council, a PTF Committee, and staff used survey data as they assessed how OCSI is doing on 8 accreditation standards.
  3. Planning for growth is based on our assessment of practice. ACSI requires that we use assessment results to identify (only) 2-3 strengths and 2-3 growth areas. The Steering Committee and Leadership Team identified key strengths and growth areas (which were then used to update the ongoing Schoolwide Action Plan).
To learn more about…

What’s next? 
  • We are now preparing for the March 13-16 accreditation visit. A team of 5 educators will review our report, visit classes, study documents, hold meetings (with students, parents/guardians, staff, and the board), identify our strengths and growth areas, and report their findings to us and OCSI’s 2 accreditation agencies: the Association of Christian Schools International and the Western Association of Schools and Colleges. We will use the team’s findings to refine our Schoolwide Action Plan.
  • We are working to further involve students and parent/guardians in our ongoing improvement process.
Did you know…?
  • The College Board provides college and SAT prep materials?
  • Part of OCSI’s vision is students using their learning to serve God and others?
  • OCSI started in 1957, used to be located in Urasoe, and moved to Yomitan in 1996?
  • That dates for next school year are posted on our community calendar? School begins on August 21, 2018 and ends on June 12, 2019. The schedule is similar to this school year, except that Christmas vacation is longer.
  • OCSI publishes a variety of informative blog posts each month?
Focus on others first

Key dates:
  • 3/13-16: Accreditation visit: A team of 5 educators (led by Dr. Mohler of ACSI) will read our accreditation report, visit classrooms, look at documents, hold meetings, and identify OCSI’s overall strengths and growth areas.
  • 3/21: Conferences
  • 4/2-6: Spring vacation
  • 5/4: Golden Week Holiday – no school
  • 5/28: Memorial Day – no school
  • 6/13: Last day of classes
  • 6/21: Summer school begins
  • 7/4: Independence Day – no school
  • 7/17: Summer school ends
  • 8/21: Classes begin (see the community calendar for key dates for next school year)

Thank you for the privilege of assisting you with the education of your child(ren)! Please contact us with your questions and concerns.

Students serve others

February 19th, 2018|

Thanks for being involved in God’s work in Okinawa

Through daily devotions, we’ve been encouraging our students to focus on others first. To put this into action, our students were involved in service projects:

  • Ministering to homeless people by providing food and fellowship.
  • Using the arts (drama, music, art, and dance) to present the Gospel at 5 different locations.
  • Cleaning up local beaches and a local zoo.
  • Supporting the outreach of a church in Saipan.
  • Visiting several nursing homes, where they met the residents and played games with them.
  • Doing odd jobs for 2 churches.


Please continue to pray for God’s work in Okinawa, Japan:

  • Praise God for providing opportunities for students to use their learning to serve others.
  • Praise God for providing an elementary teacher for next year.
  • Ask God to provide 3 bus drivers and 5 bus monitors.
  • Ask God for the health, energy, and wisdom staff need as they serve at OCSI.

Thanks for being involved in God’s work in Okinawa, Japan!
