Oh, it was an honor to be allowed in the experimental class, his mom kept telling him.

The experimental class was a success and quickly grew.

Since 2007 there have been experimental classes of the last two primary school grades (7th and 8th grade).

"Minotaur is the first unit of a new, experimental class," she told them.

At the private school, students in the experimental class received the cooperative learning program for 90 minutes each day, twice a week, for four weeks.

Many of the boys made fun of the experimental classes when left to their own devices.

At the public school, students in the experimental class received the Jigsaw program for an hour a day, five days a week, for three weeks.

The experimental classes worked in jigsaw groups for 45 minutes a day, three days a week, for six weeks.

All the students in the experimental classes are enrolled into universities upon graduation without having to take the entrance examinations.

In 2000, experimental classes were set up with the purpose of enhancing high-level personal teaching of the most able students.
