Kasetsu-Jikken-Jugyo(Hypothesis-Experiment Class)

What is Kasetsu-Jikken-Jugyo(Hypothesis-Experiment Class)?

*Hypothesis-Experiment Class(HEC)*, is an excellent Japanese class format originally established by Dr. Itakura in 1963 as both a general method of science education and a set of specific implementations of that method.
Original Japanese name of *Hypothesis-Experiment Class* is *Kasetsu-Jikken-Jugyo*.
Abbreviation for Kasetsu-Jikken-Jugyo we often use Kasetsu. ( HEC is also available for Hypothesis-Experiment Class.)
In essence, the Kasetsu process is multiple sequential cycles of Problem > Expectation > Discussion > Experiment based on Itakura’s theory, in which recognition of scientific truth is established only through experiment. The Classbook used in Kasetsu is unique among traditional textbooks. It includes tasks for teachers as well as for students, and guides the class with specific instructions,so we call it the Jugyo-sho(HE-Classbook) in order to distinguish its function from conventional textbooks.
Almost all classes run with the Jugyo-sho demonstrate good reproducibility of class performance independent of teachers and students. Additionally, around 80-90% of students report that they “liked” or “really liked” classes run using these Jugyo-sho classbooks.
Attractive Jugyo-sho classbooks in various fields have been developed and utilized in all grades from primary education to university liberal arts education. And recently, several Kasetsu classes have been put into practice in international settings, so we expect and hope for further adoption and expansion of Kasetsu.
